AIDA-Tech Vol. 2 Hydraulic Overload Protection HOLP Volume Two Hydraulic Overload Protection The Silent Sentinel Author: Steve Overly, Vice President Domestic Sales, AIDA-America Corporation Where can I find it? What is HOLP? HOLP is nearly always located near the Hydraulic Over Load Protection (HOLP) lower end of each connection. The upper is a system that senses an overload portion of the HOLP system remains condition in a mechanical press and stationary during activation while the releases hydraulic pressure in a collapsible lower portion is free to push upward with cylinder, thereby allowing the slide to be the slide, thus relieving the overload. (See pushed upward by the overload force. The Figure#1) primary purpose of the system is to prevent damage to the press in the event of Why do I need it? overload. It is a standard feature on Your press is a major long-term modern, well-designed general-purpose investment and often is operated by presses. someone without extensive training. Overload can happen through What else does it do? unintentional error or by unnoticed In addition to protecting the press change in the die or material. Without components, HOLP can at times: HOLP, press overload can result in • Help protect a die damage to the press structure, bearings, • Stop operation in a dangerous gears or clutch. At a minimum, condition uncorrected overload results in reduced • Release a press that is stuck on press accuracy and service life.

The inclusion of • Sense extreme off-center loads an effective HOLP in the press design provides an automatic protection that helps to keep the press in service. Additionally, HOLP provides a quick and easy method to release a press that has been stuck at the bottom of the stroke. This can happen easily if the shutheight setting is not correct for the die, occurring most frequently during die setup. Figure #1 Copyright © 2000 AIDA-America Corporation.

While simple • Setting the shutheight too low in design, it has performance drawbacks. • Loading a die that requires too much (See Figure #3) tonnage • Slugs or foreign material lodging in the die • Misfeed or buckling of the material • Wear in a die • Improper positioning of a die • Using incorrect material • Changes in material hardness or thickness It is important to remember that a press overload can occur on one side of a multi- Figure #3 point press and not the other. In fact, this is the most common overload condition. • It is difficult to adjust accurately The total tonnage requirement of the die is • It is slow to react • It must relieve the oil cavity through a small opening • It can be difficult to actuate HOLP units simultaneously in a multi-point press • It is prone to leakage as it nears the actuation point, causing sponginess Figure #2 not the only measure. For example, a 400- ton die will overload a 400-ton press if more than 200 tons of the load are under one connection. (See Figure #2) What types of HOLP are there? HOLP systems can be easily differentiated by the type of actuation mechanism utilized. There are several basic methods: Figure #4 CHECK VALVE – This is the oldest, SOLENOID VALVE – The most most inexpensive triggering method in common method of actuation, this system uses a solenoid valve to open a drain line when the oil pressure limit is exceeded.

What happens in overload if I don’t have HOLP? Without HOLP, an overloaded press will give at its weakest point. This can cause a stretched tie-rod or upright, bent crank or eccentric shaft, crushed bearing, broken connection pin or adjustment screw, cracked bed, slide or crown, or a slipping or damaged clutch. Even if the press survives overload without breaking, its Figure #5 clearances can be increased and parallelism destroyed.

  • Introduction
    Notes All translations from the Japanese are mine unless otherwise indi- cated. I cross-reference citations from Genji monogatari to their location in the complete English translation by Royall Tyler listed below and cross-reference to complete English translations of works other than Genji monogatari where possible. Introduction 1 The term “real-and-imagined” is borrowed from Soja, who develops the concept in dialogue with Lefebvre’s analysis of how space is produced via (1) spatial prac- tices, (2) representations of space, and (3) representational spaces. Lefebvre’s “representational spaces” provide key elements of Soja’s notion of the real-and- imagined. Both concepts emphasize a dialogic relationship between material/ historical spatial productions and imaginary or representational ones: “The repre sentational space . overlays physical space, making symbolic use of its objects. Representational spaces . need obey no rules of consistency or cohesiveness. Redolent with imaginary and symbolic elements, they have their source in history—in the history of a people as well as in the history of each individual belonging to that people.” Lefebvre, Production of Space, 33–42; Soja, Thirdspace, 74–82. 2 Ueshima, “Daikibozōei no jidai,” 15–94. The “mid-Heian period” refers roughly to 900–1050, when heads of the northern house of the Fujiwara consolidated their hold on imperial marriage politics and came to wield nearly hegemonic author- ity over the imperial court as regents and chancellors. 3 TheGenji narrator makes this comment in describing the first round of illustrated tales assembled in the picture contest in chapter 17 (Eawase).

  • Yosano Akiko's Princess Saho and Its Multiple Speakers
    WASEDA RILAS JOURNAL NO. 8 特集 5 特集 5 RILAS 研究部門「創作と翻訳の超領域的研究」 Yosano Akiko’s Princess Saho and its Multiple Speakers Janine BEICHMAN Abstract To translate is to interpret, and this is especially so for a difficult poet like Yosano Akiko. The translator con- fronting the task of interpreting the stupendous number of poems that Yosano Akiko (1878-1942) published over the course of her career begins, of course, by looking into the biographical background and reading as many com- mentaries as possible, but often that is not enough. Then come such avenues of inquiry as comparing iterations of the same themes within the corpus of the poetry itself, picking up echoes of Japanese classical and other litera- tures, and noting connections to Western literature, art, and ideas. In working with the poems here, I have used all these avenues. There is also one other approach, and that is to cycle between Akiko’s prose and her poetry. She often touched on the same topic and themes in both genres, sometimes using the prose to explain the poetry and even vice versa. The essay “Bosei Henchō wo Haisu” (I oppose the glorification of motherhood, 1916) is usually considered only in terms of its role in the public debate on the protection of motherhood (bosei hogo ronsō) that Akiko car- ried on in the media between 1916 and 1919, but it also provides a good background for reading her poetry. This is because Akiko explains her criticism of the glorification of motherhood by eloquently articulating her concep- tion of the self as multi-focal, a conception which in a certain sense is the philosophical counterpart of the multiple speakers that populate her poems.

  • The Exchange of Power and Cultural Attitudes As Authentic Practice in Japanese EFL
    1 The Exchange of Power and Cultural Attitudes as Authentic Practice in Japanese EFL Pedagogical Spaces John Clayton Phase III Part C: Dissertation Submitted to Doctoral Program Committee: Dr. Virginia Gonzalez (Chair) Dr. Susan Watts-Taffe (Co-Chair) Dr. Annette Hemmings Dr. Mary Benedetti As a partial fulfillment of the requirements for the Doctor of Education Degree (Ed.D) in Literacy and Second Language Studies: TESL Specialization University of Cincinnati Spring, 2011 2 ABSTRACT: This is a study of how EFL teachers’ cultural and linguistic backgrounds and attitudes are articulated as authentic and powerful practices in pedagogical spaces (Presence.) Presence is defined using a poststructuralist framework as the production of meaningful interactions between teachers and students in classroom settings. Using a qualitative research design, three case studies of Japanese EFL teachers at a rural Japanese High School were used, collecting data on- site from interviews, observations, lesson plans, and school reports. The results showed Presence when teachers articulated authentic and powerful language pedagogy directly connected to their attitudes and cultural and linguistic backgrounds, and not simply through the automatic delivery of the prescribed lesson. Theoretically, results critically rethink EFL pedagogy; authentic language practice is a continuum of multiple, site-specific relationships demanding mutual intelligibility, not the application of a decontextualized curriculum. Educational implications offer evidence for integrating

  • Characteristics of Group Oral Interactions Performed by Japanese Learners of English
    Characteristics of Group Oral Interactions Performed by Japanese Learners of English A doctoral dissertation submitted for the degree of Doctor of Education Graduate School of Education Waseda University Junko Negishi 2011 Abstract Group oral test formats have recently been added to the types of oral performance tests. This is because the assessment of second language (L2) learners’ authentic conversational competence is considered important in the current era of globalization. However, only a few studies dealing with group oral interaction have been carried out to date. This study aimed to identify some characteristics and developmental phenomena of Japanese learners of English by investigating what happened when they underwent group oral interactions in groups of three. Participants comprised of 145 students from junior high schools, senior high schools, and universities. Ten Japanese raters assessed the participants utilizing criteria of the Common European Framework of Reference (CEFR; Council of Europe, 2001) which is currently being used throughout the world. In order to explore the feasibility of employing Japanese raters and adopting the CEFR criteria, first, three facets—the severity of raters, the difficulty of rating categories, and participants’ speaking ability—were examined by means of multi-faceted Rasch measurement, which analyzed sources of variation and estimated “measures” from the raw scores given by raters. Secondly, the participants’ discourse was investigated from various points of view based on five subcategories in the CEFR criteria: Range, Accuracy, Fluency, Interaction, and Coherence. The analysis was carried out ii on 82 discrete items that might have the potential to explain speakers’ development. Next, participants’ characteristics which exhibited developmental features and had relationships to the CEFR criteria were identified and further explored.

  • Common Feelings of Survivors of Sexual Assault
    Common Feelings of Survivors of Sexual Assault Emotional responses of survivors will vary from individual to individual. Sexual assault can be extremely traumatic and life-changing. It’s important to remember that your responses are not crazy; they are normal reactions to a traumatic situation – sexual assault. Our goal is to offer support, options and resources that encourage empowerment and healing. Below are some common questions and feelings survivors of sexual assault may experience but it is not necessarily an exhaustive list. Why did this happen to me? You didn’t do anything wrong. It’s not your fault. Your power was taken away by someone else. Sexual violence can happen to anyone, regardless of age, gender, race, religion, etc. One in three women and one in six men are sexually assaulted at some point in their lifetime. When will I be okay? When will this be over? When will I stop feeling so bad? It is hard to understand that someone would do this to you and that there would be so much pain. It isn’t fair but you did survive. You are strong and courageous. There is no blueprint for healing. It is on your own time schedule and in your own way. There are people who can help you if you need it. How do I get over this? No one was taught how to heal from a trauma, so it’s scary. There are no simple 10 steps to healing but healing is happening. Talking about it is a very important healing tool. Sexual assault is not something that any individual will ever “get over” in their lifetime, more, it becomes an experience that makes up the character and being of the victim/survivor that has no more or no less impact on the individual than any other life experience.

To my committee members: Mimi Long, René Lysloff, Jonathan Ritter, and Christina Schwenkel, I had the privilege of taking seminars with each of you that inspired me deeply and prepared me to embark on my fieldwork and research. Thank you to all for your vital input and advice on this project. At UCR, I am also grateful to supportive colleagues, mentors, and staff who helped make my overall graduate studies experience a very positive one. This project would also not have been possible without support from the UCR Graduate Research Mentorship Program award (2014-2015) and the Japan Foundation Doctoral Fellowship (2015-1016), which made it possible for me to spend a generous two years conducting fieldwork in Japan for this project.
