    • A fuel cell having an oxygen-containing gas flow field and a fuel gas flow field, an oxygen-containing gas supply apparatus for supplying an oxygen-containing gas to the oxygen-containing gas flow field, a fuel gas supply apparatus for supplying a fuel gas to the fuel gas flow field, a scavenging gas supply apparatus for supplying air as a scavenging gas to the fuel gas flow field, and a controller are provided. The controller includes a voltage detection unit for detecting the voltage of the fuel cell after operation of the fuel cell is stopped and a scavenging control unit for starting scavenging in the fuel gas flow field by the scavenging gas supply apparatus after the detected voltage is decreased temporarily, increased, and decreased again to become a preset voltage or less.

    • An improved telephone set of the type including a telephone body and a handset adapted to be placed on the former wherein the telephone set includes features which prevents displacement of the handset from the telephone body. The telephone body has a pair of engagement blocks incorporated therein of which part is projected outwardly of the telephone body and they are fitted into engagement recesses on the handset whereby the latter is firmly placed on the telephone body. At least the one engagement block has an engagement face which is adapted to come in contact with the engagement portion in the corresponding engagement recess, wherein each engagement block includes a pawl portion. Displacement of the handset occurs by displacing one of the pawl portions out of its respective engagement recess followed by displacement of the handset in a second direction which is different from the first direction which causes the displacement of the other pawl portion out of its respective engagement recess. Thus, the handset is reliably held on the telephone body.
    • 一种类型改进的电话机,包括电话机和适于放置在前者上的手机,其中电话机包括防止手机从电话机构移位的特征。 电话主体具有一对结合在其中的接合块,其中一部分从电话主体向外突出,并且它们装配在手持机上的接合凹部中,由此将其牢固地放置在电话机上。 至少一个接合块具有适于与相应的接合凹部中的接合部分接触的接合面,其中每个接合块包括棘爪部分。 手柄的位移是通过将棘爪部分中的一个从其相应的接合凹槽中移位,随后手柄在与第一方向不同的第二方向上的位移而发生的,该第二方向导致另一棘爪部分从其相应的接合凹部 。 因此,手机被可靠地保持在电话机身上。
