摘要： PURPOSE:To prevent freezing of a primary cooling system without eliminating the need for additional consumption of a power and through sharp reduction of a consumption power by a method wherein by using a temperature detector, the motion of a secondary cooling system is controlled while the water temperature of a primary cooling system is controlled. CONSTITUTION:A device is provided with a temperature detector 13 adapted to detect the water temperature of a primary cooling system and a control circuit 14 to receive temperature detected by the temperature detector 13 and turn ON and OFF the motion of a pump 9 and a fan 12 for cooling of a secondary cooling system. The control circuit 14 detects the water temperature of a primary cooling system and stops the fan 12 for cooling when a water temperature is decreased and further stops the pump 9 when it is further decreased, and prevents the occurrence of freezing due to lowering of a water temperature. This constitution enables sharp suppression of consumption of a power for prevention of overcool through control of the motion of the secondary cooling system according to the temperature of cooling water of the primary cooling system.

摘要： PURPOSE:To improve the operational property of an electron tube and realize a stable operation for a long period of time, by furnishing a low reflection layer with a black surface at the inside of an anode. CONSTITUTION:At the inner surface of an anode 1 of an electron tube, a low reflection layer is furnished. This low reflection layer is composed of two layers, a metallic layer 22 and a metallic oxide layer 23, formed on a nonoxygen copper layer 21 which composes the anode 1. Although a black low reflection layer is formed with the looking at the surface, it is not necessary restricted to such a layer, but any antiheat layer to absorb heat rays will do.
