    • An explosion preventing device for a refrigerating machine using a flammable refrigerant according to a first embodiment of the present invention comprises a mesh member which covers a part or component or a control section. The mesh member has a mesh size which is equal to or smaller than a quenching distance for the flammable refrigerant used. By covering the part or the like which may generate electric sparks, with the mesh member having the mesh size equal to or smaller than a quenching distance, as described above, even if the sparks are generated to produce flames, when the refrigerant is leaked, the flames cannot be propagated to the outside of the mesh member. Therefore, even if the sparks are generated when the refrigerant is leaked, a serious explosion or fire cannot be caused.
    • 根据本发明的第一实施例的使用可燃性制冷剂的制冷机的防爆装置包括覆盖部件或部件或控制部的网状部件。 网状构件的网眼尺寸等于或小于所使用的可燃性致冷剂的淬火距离。 如上所述,通过覆盖可能产生电火花的部件等,网格尺寸等于或小于淬火距离,即使产生火花产生火焰,当制冷剂泄漏时, 火焰不能传播到网状构件的外部。 因此,即使在制冷剂泄漏时产生火花,也不会引起严重的爆炸或火灾。

    • In a non-contact type IC card, a re-access inhibition time setting circuit 12 sets a re-access inhibition period of time for inhibiting the re-access for a fixed period of time after an operation of a main circuit 16 is finished. This prevents a double write operation of history in the card due to the re-access in a short period of time. Moreover, two areas 321 and 322 are disposed in a memory 32 to write data alternately in these areas. In a read operation, when data of one of the areas is destroyed, the normal data in the other area is read; whereas, when each data is normal, the data last recorded is read. Consequently, the disabled state of the read operation due to wrong data can be prevented.
