Title: Superconductive wire rod and superconductive coil
Inventor: TADA NAOFUMI
IPC: A61B5/055
Filed: 1989-07-21
Abstract: PURPOSE:To reduce quenching at the time of high-speed float transit while improving reliability by specifying a sectional area ratio of (Cu + Al)/NbTi, and a sectional area ratio of Al/Cu. CONSTITUTION:A sectional area ratio of (Cu + Al) NbTi 3 of a superconductive wire rod having the finest multi core of NbTi coated with Al 4 built in the cross-sectional central part of a superconductive wire rod 1 and Cu formed on a cross-sectional peripheral part of the superconductive rod 1 shall be 0.5 to 3.0, while a sectional area ratio of Al/Cu shall be 0.05 to 0.5. Accordingly, even when a matrix ration of the wire rod is small, coil current density can be increased so that float force can be increased due to the small size and light weight of a superconductive coil for a magnetic leviation train. Thereby, provided the leviation force is constant, high-speed leviation transit becomes possible by means of the superconductive coil of the smaller magnetomotive force while reducing manufacturing cost of the coil increasing the number of passengers per vehicle as well preventing quenching of the superconductive coil on the car.

Title: Forming method of center cap
Inventor: KAWABATA ISAMU
IPC: H04R7/12
Filed: 1980-12-25
Abstract: PURPOSE:To prevent generation of a defective, by pressing so that the surface of a dome part is not flawed. CONSTITUTION:A spherical projecting part of an upper metallic mold is pressed against a material from the tip side, and a dome part is formed on the material. In this case, it is formed so that the dome part does not contact with the inside of the hollowed part of a lower metallic mold. Even in case when there is a vapor-deposited film on one surface of the material, damage of the surface of the dome part is prevented by directing said film to the lower metallic mold side. Also, distortion of the dome part is prevented by placing and supporting the material by the circumferential edge between the upper and lower metallic molds.

IPC: B29C48/92
Filed: 1988-07-29
Abstract: PURPOSE:To improve the energy efficiency as high as is equal to that achieved by a purely electrically controlling system, by allowing a controller to receive a position signal from a projecting position sensor indicative of the projecting position of a pressuring shaft such as a rod or the like and a pressure signal from a pressure sensor which detects a speed signal from a pressuring shaft projecting speed sensor and an output liquid pressure from a liquid pressure pump, thereby to generate a control signal. CONSTITUTION:A controller 1 indicates a servo amplifier 2 to control the rotating speed and torque of a servo motor 5. At the same time, the controller 1 also controls the discharge amount of a variable capacity pump 4 of a two-way type. Detectors 9, 10 detect the liquid pressure of an A boat of a cylinder 8 and the projecting degree and speed of a rod 12 of a cylinder 6, respectively. The detected values are fed back to the controller 1. By the above circuit structure, the projecting shift of the cylinder rod 12 can be controlled by time and also the projecting speed and projecting force (pressure) can be controlled corresponding to the shift by a program loaded in advance into the controller 1. Therefore, the protruding volume and pressure of a material can be freely controlled if the material is protruded by this rod 12.

Filed: 1990-07-17
Abstract: PURPOSE:To eliminate the need for subjecting all products to the inspection of defective and to reduce the inspection cost for quality control by outputting a 1st alarm when a work is detected by a work detecting means and outputting a 2nd alarm when an inspection signal is not outputted and the work is not detected by the work detecting means. CONSTITUTION:Whether the output of an IR temp. sensor 32 is on or not is discriminated when the result of the discrimination of a controller 30 is affirmative and a tracking signal is outputted (on). If the result is no, this result means that the product is not detected in the final stage and that the forged blank material having the possibility of including a joint part is correctly expelled at the point of the time when the material is cut out by a cutting machine 10. The controller 30 lights a blue lamp 38a in this case. If the result of the discrimination is yes, this product is worked from the blank material ought to be expelled in the cutting out stage and, therefore, the controller 30 decides that this product is defective. The red lamp 38c of an alarm device is then lighted.
