Filed: 1995-06-01
Abstract: PURPOSE: To obtain a joining method having good joint strength approximate to the strength of a copper-base metallic material in friction pressure welding of a tungsten-base metallic material and the copper-base metallic material. CONSTITUTION: The joint having the good joint strength to cause rupture near the base metal part of the copper-base metallic material in tension test is produced if the tungsten-base metallic material and the copper-base metallic material are subjected to friction press welding by interposing a niobium-base metallic material as an insert material (a method of using a foil material or of forming a film by an ion plating method, plating method, etc., is equally well) between the groove faces to be joined. The joint strength (the tensile strength is fairly lower than the tensile strength of the copper-base metallic material and the joint ruptures mainly near the press welding face) in the friction press welding of the tungsten-base metallic material and the copper-base metallic material without using the insert material is improved in the friction press welding method.

Title: Braking control for windmill power generator
Inventor: EGUCHI NORIO
IPC: F03D7/06
Filed: 1981-10-07
Abstract: PURPOSE:To enable a windmill to be stopped in a short time with a large brake power when the revolution speed of the windmill power generator increases close to the breakdown limit in case of a strong wind, by installing a mechanical brake, and to reduce the grade of the breakage of the apparatus even if the power generator is started with brake application. CONSTITUTION:When a windmill power generator 28 is brought closely into the hait state by application of an electromagnetic brake 24, the electromagnetic brake 24 is released, and a mechanical brake 29 is applied. Said brake 29 is operated in the friction system with the spring force, and an electromagnetic solenoid is energized in case of both setting ON and OFF of the brake 29, but the brake 29 does not require supply of the energy in case of locking revolution. As the revolution power generated by a Dalius-type windmill in stop state is remarkably small, the windmill power generator can be kept in the hait state for a long time by the friction system 29 with a spring force having a relatively small brake power even in a strong wind range. Further, even if the power generator is started with the erroneous application of brake, water-out of brake shoe can be reduced.
