Title: Vacuum valve
Inventor: YOKOKURA KUNIO
IPC: H01H33/66
Filed: 1990-10-01
Abstract: PURPOSE:To obtain an excellent large current shutting function and suppress regenerated arc generation owing to the surge voltage generated by shutting small current to prevent generation of a large surge voltage by installing a coil, which generates a magnetic field in the same direction as the axial direction of a fixed shaft and a movable shaft in the space between the fixed side contact point and the movable side contact point owing to shutting current, only a fixed shaft side. CONSTITUTION:A coil, which generates a magnetic field in the same direction as the axial direction of a fixed axis 7 and a movable axis 8 in the space between the fixed side contact point 2 and the movable side contact point 3 owing to shutting current, is installed only in the fixed axis 7 side. Consequently, at the time of shutting large current, a magnetic field in the axial direction is provided to the arc generated between the fixed side and movable side contact points 2, 3 and the arc is dispersed uniformly to be stabilized and the melting of a contact point is suppressed to shut current excellently. Also, the total mass of the movable axis 8 becomes small and the pole opening speed is increased, so that the pole opening is carried out within a short time. Consequently, regenerated arc generation owing to the surge voltage generated by small current shutting can be suppressed to prevent progress to large surge voltage generation.

Title: Positioning pin
Inventor: SASAKI YOSHIO
IPC: F16B19/02
Filed: 1990-10-01
Abstract: PURPOSE:To obtain a positioning pin excellent in wear resistance, sufficiently resisting the mechanical impact in time of insertion and pulling out of a sheet metal and capable of drastically prolonging a life by inserting the axial part of a metallic introducing member into the through hole of a ceramic positioning member and screwing down a metallic introducing member and a metallic fixing member with a soldered screw part provided on that axial part. CONSTITUTION:The ceramic positioning member 2 is positioned on the upper surface of the fixing member 1, the axial part 4 of the introducing member 3 into the through hole of the member 2 is inserted to screw down the member 3 and the member 1 with the soldered screw part 5. In this way, the looseness of the screw part due to mechanical impact given in time of insertion and pulling out of the sheet metal is made difficult to occur. Solid solder is considered as solder but since pasty solder made by mixing metallic powder and flux can coat the screw part uniformly and is excellent in workability, it is more suitable than solid solder. Organic series binder and fixing by welding are considered other than a soldered screw part but the organic series binder is carbonized by heat and does not express locking effect. On one hand, in the welding. the fixing force in the screw part is as strong as solder but when a large torque is given and looseness occurs once, the fixing force lowers rapidly and locking effect can not be exhibited.
