The insulating base material is composed of aluminum oxide and/or aluminum hydroxide and mica power. The zinc borate hydrate is composed essentially of 2ZnO.3B.sub.2 O.sub.3.3H.sub.2 O. The arc resistant insulator is prepared by mixing the insulating base material with a zinc borate hydrate forming material composed of normal boric acid, boric acid anhydride and zinc oxide and heating and compacting the mixture thus obtained in a closed system at a temperature of at least 155.degree. C. under pressure of at least 50 kg/cm.sup.2.

摘要： The present invention is a heat treatment jig for use in the baking process, the frit seal process, and the evacuation process during the manufacture of cathode-ray tubes. It comprises a base and one or more support members formed from a novel material comprising mica, talc, orthoboric acid, boric acid anhydride, and zinc oxide molded under heat and pressure. This novel molded material is superior in its mechanical properties to the substances (asbestos tape, asbestos cement, or boron nitride) used for the support members of conventional heat treatment jigs. In addition, it does not pose a danger to health like asbestos products and it is far lower in cost than boron nitride.

摘要： A switch containing a switch case, contacts adapted to be opened and closed, an arc extinguishing chamber disposed in the vicinity of the contacts, and an arc extinguishing material capable of reducing the amount of metal particles and free carbons to be scattered from components disposed within the switch by an arc generated when the contacts are opened or closed or capable of insulating the metal particles and the free carbons to convert into an insulator, thereby inhibiting a decrease in arc resistance expected to occur upon the generation and extinction of the arc and a decrease in insulation resistance expected to occur within and around the arc extinguishing chamber and at inner wall surfaces of the switch case upon and after the extinction of the arc. The switch is applicable to a switch expected to generate an arc upon interruption of electric current flowing therethrough such as a circuit breaker, current-limiting device or electromagnetic contactor and is capable of immediately extinguishing the arc and inhibiting the decrease in insulation resistance within and around the arc extinguishing chamber and at inner wall surfaces of the switch case.
