The MUSASHI confined more than 1 × 107 of antiprotons and extracted them as ultra-slow antiproton beams with energy of 250 eV and var- ious bunch lengths.

The magnetic 04 Hadron Accelerators 4188 T01 Proton and Ion Sources Proceedings of IPAC’10, Kyoto, Japan THPEC058 field strength was chosen to set 2.5 T for better trapping efficiency and at the same time for better focusing of low energy beams from strong magnetic field to non magnetic field region. The uniformity of the magnetic field in the UHV bore was designed and achieved to less than 0.1% for stable confinement. The UHV bore made by nonmagnetic stainless steel clad by Cu strips was kept at around 4 K by also two GM-type cryocoolers which thermally connected through oxygen- free high thermal conductivity copper mesh. The tempera- ture difference between the center and the both ends where GM-cryocoolers were connected was 0.2 K. Since the p¯s spent a long time in the trap, more stringent vacuum conditions were required there to avoid annihila- tion on residual gas atoms [5] than in the RFQD, through which they passed only once. Two 90 μg/cm2 (0.65 μm thickness) polyethylenterephtalat (PET) foils located 70 cm upstream of the MRT were therefore used to isolate the trap and RFQD vacuum systems, at 10−12 mbar and 10−9 mbar, respectively. Since these foils were some 800 times thinner than those used at the entrance of the traps described in Ref.[4, 6, 5] of 99.9% in total stopping direct beam from the AD at 5.3 MeV by thick degrader foils, only 30-40% of decel- erated p¯s were lost at the foil.

  • The Development of Japanese Cotton Weaving Industry in Edo Period
    Takeshi Abe Osaka University [email protected] The Development of Japanese Cotton Weaving Industry in Edo Period Introduction Prior to the Japanese industrialization which began in the late 1880s, manufacturing such as weaving, silk reeling, brewery, and the related commerce had already highly developed around the farming villages in the Edo period (1603-1868). We have many Japanese books and articles that argued about the Japanese manufacturing in the period, especially after the latter half of 18th century1. However, most of them argue about only one industry at a specific narrow area, and neglected the development of the industry in the whole Japan. In addition, such basic facts as the starting period of the respective local industries, the transition of their production, and so on, are not necessarily known, although the literature well elucidated the differences of production forms (i.e., putting-out or manufactory). There were lots of manufacturing industries in the Edo period. Table 1 shows the production values of the important industries in 1874, which reflect the approximate situation at the end of the Edo period. According to this table, brewery and weaving were most important, and in weaving, cotton and silk were overwhelming. This paper focuses on the cotton weaving industry, and confirms quantitatively the transition of production volumes, further considering about some aspects of its development all over Japan. 1 Ichikawa (1958) is an excellent survey about them. 1 1. Basic Data In the Edo period, with the penetration of market economy, cotton cloth, which was the material of popular kimono and the other wear, came to be woven in the many local areas, closely related to the production of raw cotton and hand-spun yarn.

  • Himeji – (2 Hours) Dinner and Overnight in Himeji
    Travelling the path of Musashi *Note: This itinerary doesn’t follow Musashi’s life in chronological order due to travel logistics. It does however, begin and end at his place of birth and death. The trip begins with a flight to Osaka, Japan. Depending on when flights arrive (day or evening) will dictate on which day the true itinerary begins. Day 1: Mimasaka Visit Musashi museum/shrine; believe to be the birthplace of Musashi. (About an hour visit) Depart Osaka by train [Japan Railways Limited Express operates a train from Osaka to Mimasaka, every 4 hours. Tickets cost $30 - $45 and the journey takes 1 h 37 min.] It is ten minutes on foot from Chizu railroad Miyamoto Musashi Station. Taxi to Hirafuku – 30 min ride from Mimasaka to Hyogo Sayo-cho in Hirafuku. At the age of 13 years old, Musashi challenged Kihei Arima who practiced Katori Shinto Ryu. Musashi attacked with a staff, and Kihei defended with a Wakizashi. Masashi threw Kihei to the ground with his hands, and then beat him to death as he tried to get up. Train to Himeji – (2 hours) dinner and overnight in Himeji Day 2: Himeji In his 30’s; Musashi helped in the construction of Akashi Castle and helped organize the layout of the town of Himeji. During his stay, he taught martial arts, particularly kenjutsu and shuriken throwing, and he perfected his Enmei-ryu kenjutsu style. Visit castle and local sites. Train to Sekigahara 2.5 hours. (0vernight in Sekigahara town) Day 3: Battle of Sekigahara Sekigahara was the biggest, the bloodiest, the most violent and most important of all samurai battles, fought between the factions of a nation divided in two, East and West.

  • Shimonoseki: a Town with a 1000 Year-Old History
    Shimonoseki: a town with a 1000 year-old history Shimonoseki, situated on the westernmost end of the mainland of Japan has prospered as a gateway to Eurasia as well as a strategic stop for land and sea transport in the area. The town, boasting attractive scenery along the Kanmon Strait, has witnessed so many important events in Japan’s history that it forms an integral part of its culture. As the location of a famous naval battle in the War between the Genji and the Heike clans in 1185, Shimonoseki played a key role in the transition from aristocratic to warrior rule in Japan. The city has places of natural beauty and historical interest typical of a castle town, such as ancient samurai residences and clay walls. Visitors will enjoy the distinctively Japanese atmosphere they exude. With its wealth of historical sites, ethnic ambience, beautiful scenery and Japanese food, Shimonoseki is a town that will capture your heart.

Instead of presenting literary representations of prevailing Meiji ideological positions such as risshin shuss. (rising in the world) entrepreneurism and success scenarios for men or ry6sai kenbo (good wives, wise mothers) domestic scenarios for women. S6seki focuses on erotic triangles which expose gender difference and gender inequalities of Meiji-Taish6 Japan. Investigation of fictional erotic triangles also reveals the possibility of homosocial desire in an age when discourse was increasingly antithetical to non-nonnative expressions of male-male desire. Soseki's gender representations frequently invert conventional gender expectations with his depictions of passive males and women desiring mastery over the male, and these depictions in tum are mapped and analyzed throughout the novelist's brief ten-year career as a novelist.
