Title: Load support structure of superconducting magnet, load supporter and magnetic levitation train
Inventor: HATTORI TOSHIO
IPC: B61B13/08
Filed: 1990-10-24
Abstract: PURPOSE:To reduce the intrusion of heat to an internal tank, and to obtain strength sufficiently by forming the external shape of the side face of a supporter supporting the internal tank in a shape that the external shape is constricted gradually extending over approximately a center from both ends. CONSTITUTION:An internal tank 2 held at the temperature of liquid helium and an external tank 6 sustained at an atmospheric temperature are connected by one hourglass type load supporter 3, and floating force, driving force, etc., working to a coil 1 are received by the load supporter. A thermal anchor 4 is installed to an hourglass- shaped intermediate section, and the thermal anchor 4 is coupled thermally with a shield plate 5 held at the temperature of liquid nitrogen, thus reducing the intrusion of heat from the external tank 6 to the internal tank 2. When the position of the thermal anchor 5 is brought near to the external tank 6, the penetration of heat to liquid nitrogen is increased, and the penetration of heat to liquid helium is decreased. The load supporter 3 is positioned at the center of the internal tank 2, and the internal tank 2 is supported on the truck 7 side, and is not supported on the outside (the guide rail (atmospheric) side). Accordingly, the abnormal vibrations of the internal tank 2 with vibrations at the time of travelling are prevented, and the damage of the load supporter 3 is also obviated.

Title: Method for molding water tap apparatus with synthetic resin
Inventor: FUKATSU KO
IPC: B29C45/00
Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To mold a main body of a water tap apparatus without using a sand mold or the like by a method wherein a running water hole of the tap apparatus is formed by blow molding by an injection molding process of resin. SOLUTION: A mold of a mixing tab body (a main body) 2 is fitted to an injection molding machine equipped with a gas injection molding apparatus. Modified polyphenyleneoxide resin is injected into the mold, and nitrogen gas is injected therein to form a hollow shape. When the mold is opened to take out a molded product after suitable cooling time, the main body 2 can be formed. A surface appearance of the molded main body 2 is very smooth, and a process for improvement of a raw material appearance is not required. An inner wall of the hollow part formed by injection molding of the resin is very smooth to reduce water flow resistance, and the propagation of various germs or the like can be prevented. Further, since synthetic resin is very low in a cost per unit volume and light in weight, in comparison with metal, its costing down and making light in weight can be achieved.

Title: Method of manufacturing multi-channel ion chamber radiation detector
Inventor: TAKEMURA SATOSHI
IPC: G01T1/185
Filed: 1989-10-31
Abstract: PURPOSE:To make a simple and inexpensive production possible by processing electrode support grooves in one side of the insulating board formed in a specific size by integrating a plurality of small insulating plates to make an insulating boards of a specific size. CONSTITUTION:After small insulating plates 11' are connected to integrate, electrode support grooves are processed. In addition, the small insulating plates 11' are connected before the grooves are processed and the other grooves provided in the connected parts are also processed simultaneously. Accordingly, the error of the position and the direction of local and discontinuous grooves at the connected part produced in the case where they are processed by a conventional method do not occur. Furthermore, because the work for matching the position and the direction of the grooves 12 to connect them is needed, the error in the process does not occur. Accordingly, electrode plates can be arranged at regular pitches and a multi-channel ion chamber radiation detector of a uniform space resolution can be obtained.
