    摘要: A composition for absorption refrigeration which comprises a fluorinated hydrocarbon refrigerant, an amide or glycol ether solvent serving as an absorption liquid, and a phosphite stabilizer. The stabilizer is used in an amount of 0.05 to 0.5 wt % of the absorption liquid calculated as phosphorus, within which range the phosphite stabilizer can suitably protect the refrigerant and the absorption liquid from deteriorating and decomposing at high operation temperatures.

    摘要: A level convertor is provided between circuits, which act with different power supply voltages, respectively, and converts a first voltage level of an output of a circuit to a second voltage level, which corresponds to an operational voltage level of another circuit. The level convertor comprises a level shift circuit, which receives the first voltage level and outputs an output of the second voltage level, and a buffer circuit, which receives the output of the second level and a control signal, and fixes the output of the second voltage level to a low logic level, when the control signal is a low logic level. The control signal may be used to set a timing for registering the data to a register, avoiding data in an instable state when power is supplied, from being registered to the register.

    摘要: In the method for making the magnetic recording wherein a first magnetic layer is formed on a substrate and a second magnetic layer is formed on the first magnetic layer, before forming the second magnetic layer, accelerated ions are irradiated onto a surface of the first magnetic layer. Thereby, naturally formed oxidized layer and adhered impurity on the first magnetic layer are removed from the surface of the first magnetic layer by ion etching action by the irradiation of ions, and hence a preferable condition of an interface between the first magnetic layer and subsequently formed second magnetic layer is obtained.
