  • Patent number: 4313840
    Abstract: Freon stable heat transfer oil comprising polyol ester containing tris-(alkylphenyl) phosphite and benzotriazole ##STR1## or benzotriazole derivative ##STR2## in which R.sub.1 and R.sub.2 each represents a hydrogen atom or an alkyl group. It is desirable to add tris-(alkylphenyl) phosphite or tris-(phenyl) phosphite in an amount in the range between 0.02-5% by weight and to add benzotriazole or its derivative in an amount in the range between 0.02-1% by weight to the heat transfer oil.

  • Patent number: 4129678
    Abstract: In a self-bondable insulated wire comprising a conductor and three resin insulating layers, the first resin insulating layer is formed with a resin selected from the group consisting of polyimide resins, polyamideimide resins and polyesterimide resins, the intermediate resin insulating layer is formed with a resin selected from the group consisting of polyvinyl formal resins and epoxy resins, and the outermost resin insulating layer is formed with a self-bondable resin of phenoxy series. Thus, a self-bondable insulated wire which is excellent in both oil resistance and heat resistance is obtained.

  • Patent number: 4106557
    Abstract: An apparatus for cooling a heat generating member by utilizing the latent heat of vaporization of a boiling refrigerant, having a cooling vessel including an evaporator section containing the boiling refrigerant and adapted to transmit the heat generated by the heat generating member to the refrigerant, and a condenser section for liquefying the gasified refrigerant; a liquid refrigerant reservoir open at its upper end and adapted to store a body of the refrigerant which does not directly take part in a cooling operation while the cooling operation is being performed; and a communication means for communicating the cooling vessel with the liquid refrigerant reservoir, the cooling vessel and the communication means being filled with the boiling refrigerant.
