摘要： A novel contact electrode material for vacuum interrupters is disclosed, by which the chopping current value inherent in contact material can be reduced so that it is possible to stably interrupt small lagging current due to inductive loads without generating surge voltages. The material is equivalent or superior to the conventional Cu-0.5Bi material in large current interrupting capability and dielectric strength. The material consists essentially of copper, chromium, iron or molybdenum and chromium carbide or molybdenum carbide. The metallographical microstructure is such that copper is infiltrated into a porous matrix formed by mutually bonding chromium powder, iron or molybdenum powder and metal carbide powder in diffusion state. In its manufacturing process, firstly copper is placed onto a powder mixture of chromium, iron or molybdenum, and chromium carbide or molybdenum carbide, and then the copper and the powder mixture is heated within a nonoxidizing atmosphere at a first temperature lower than the copper melting point and thereafter again at a second temperature higher than the copper melting point.

A stationary rod enters the envelope through the first disk in such a manner as to provide a seal therewith. A movable conductive rod movably enters the envelope through the second disk. A bellows is fixed at its one end to the movable rod and at its other end to the second disk in such a manner as to provide a seal about the movable rod to allow for movement thereof without impairing the vacuum inside the envelope. Stationary and movable electrodes are connected to the stationary and movable rods respectively in such a manner as to engage and disengage with each other according to the movement of the movable rod.

摘要： A process for bonding a copper or copper-chromium alloy body and a ceramic body of components of an electrical or electronic device to each other includes a step of directly sandwiching a layer of chromium oxide between the ceramic and copper or copper-chromium bodies, a step of heating a temporary assembly of the ceramic and copper or copper-chromium alloy bodies and the layer of chromium oxide, under an atmosphere which can oxidize chromium without oxidizing copper, at a temperature of at least 900.degree. C. but below the melting point of copper or the alloy, and then a step of slowly cooling the resulting bonded assembly. In particular, in a process for bonding the alloy body to the ceramic body, the chromium oxide sandwiching step is performed concurrently with the temporary assembly heating step. The bonding process can produce a hermetic envelope, particularly a vacuum envelope of a vacuum interrupter. The process for bonding the copper or alloy body to the ceramic body of this invention is more advantageous than bonding processes employing the so-called Telefunken method, in terms of cost and steps.
