Title: Manufacture of contact material of vacuum valve
Inventor: MIYAMOTO SEIICHI
IPC: H01H33/66
Filed: 1992-01-10
Abstract: PURPOSE:To reduce the fusion breaking force of a material of a contact of a vacuum valve manufactured by an infiltration method. CONSTITUTION:When a material of a conductive component 3 is infiltrated into a gap of a skeleton 2 of a refractory component, a quantity of the conductive component is made not exceeding a quantity of the gap so as to make blowholes 5 exsisting in an infiltrated material. Thereby, a vacuum valve having the small operation force can be realized by reducing the fusion breaking force.

Title: Controller for electric railcar
Inventor: KAWAZOE YUJI
IPC: H02P7/298
Filed: 1985-01-11
Abstract: PURPOSE:To eliminate a contactor for switching power drive/brake circuit by using a resistor and a contactor for controlling a field weakening and further a field weakening controller and a brake circuit at power drive time in the same manner. CONSTITUTION:A field exciter 6 is not operated in a full field range at power drive time, and a main circuit current is flowed only through a bypass diode 10. As the speed of an electric railcar rises, the resistance of a main resistor 1 is sequentially shortcircuited. A field contactor 8 is closed in a field weakening control range at power drive time, and the exciter 6 starts operating. A regenerative brake current IB is flowed to all induction branches 3 similar to the field weakening control range. A field current IF is supplied from the exciter 6 to flow a closed loop of the branches 3 and the field winding 2.

Title: Charging equipment
Inventor: MURAI TOSHIO
IPC: H01M50/574
Filed: 1987-01-10
Abstract: PURPOSE:To surely prevent dry cell from undergoing fault charge by detecting the presence of conducting current between contact parts allocated in a charging circuit, to discriminate between dry cell and rechargeable cell so that charging current does not flow even if a dry cell is mounted by mistake. CONSTITUTION:A rechargeable cell B is charged by collector current from a transistor Q1. A contact part 7 is connected with a constant voltage circuit 13. The contact parts 7, 8, a little extruded from a window part 16 formed on the bottom surface of installation part 3, make contact with a conduction part 20 of the rechargeable cell B mounted on the installation part 3. The conduction part 20 is allocated at forward or backward position deviated from the center in axial direction of rechargeable cell B. By the arrangement, if the cell B is adversely set on the installation part 3 facing the rate side in place of the front side, the situation is the same as that a dry cell having no conduction part 20 is mounted on the installation part 3 so that the contact part 7 does not conduct with the contact part 8, therefore, a charging circuit does not work and no charging current flows in the dry cell.
