    摘要: A fuel cell device individually has an electrolyte layer which is connected, in an ion conductive manner, to the electrolyte layer of a fuel cell and a half cell formed by a single electrode and a gas chamber.An electrochemical circuit for the purpose of transferring electrolyte is provided by using the single electrode of the half cell, the electrolyte layer of the corresponding fuel cell and the half cell, and either of an oxidant gas side electrode or a fuel gas side electrode. With this circuit, quick and quantitative replenishing electrolyte can be performed.

    摘要: A television receiver comprising a first printed circuit board having a helical resonator filter, an adjacent channel trap circuit and an impedance converter circuit for providing a reduced output impedance, the first printed circuit board being secured to the tuner casing, and a second printed circuit board having first and subsequent i-f amplifier stages, the two printed circuit boards being connected to each other, whereby good skirt characteristics can be simply obtained. Also, no overall adjustment is required but the tuner and i-f amplifier may be adjusted separately, thus providing improved serviceability.
