Abstract: A fuel cell in which fuel gas is more uniformly distributed to each power generation cell and irregular deformation of an interconnection section is reduced. A fuel gas channel (17) formed in a fuel arm section (22) of a separator (19) has a smaller cross-sectional area than an oxidation agent gas channel (18) formed in an oxidation agent arm section (21). Further, the fuel arm section (22) and the oxidation agent arm section (21) are formed so that their section moduli are substantially the same.

Abstract: The objective of the invention is to prevent plastic deformation of separators in a heat cycle of the fuel cell, to thereby prevent damage to the power generation cell. A laminated body is formed by alternately laminating power generation cells (5) and separators (8) having reactant gas passages (11 and 12) inside thereof, and a fuel gas manifold and an oxidant gas manifold, which are in communication with the reactant gas passages (11 and 12) of each separator (8) and extending in the laminating direction, are located at a periphery of the laminated body, and a load is applied to the laminated body in the laminating direction. The separator (8) includes: an interconnect section (8a) at a center of which the power generation cell (5) is located; and a pair of arm sections (8b) with an elongated strip shape, each arm section (8b) extending from a rim of the interconnect section (8a), and an end (8c) of each arm section (8b) being connected to the fuel gas manifold or the oxidant gas manifold.

Abstract: A switch capable of individually switching two circuits through a double action of an actuator. The switch comprises: an actuator adapted to slide in a casing by a given stroke; a spring for energizing the actuator toward an initial position; a locking mechanism for preventing the actuator from returning toward the energizing direction by the spring at an intermediate position in the stroke; primary-side contacts adapted to be switched by means of the actuator in the course of movement thereof from the initial position to the intermediate position in the stroke; and secondary-side contacts adapted to be switched by means of the actuator in the course of movement thereof where the actuator further reciprocates against the spring from the locked state at the intermediate position.

Abstract: A power supply control apparatus for a television receiver has a manually-actuable power switch for switching the power supply of the television receiver between its ON and OFF states, a digital timer for generating a time code representing the current time, a key input for generating a start-time code and an end-time code respectively representing programmable start and end times, a memory for storing the start-time and end-time codes, first and second coincidence detectors for generating first and second coincidence outputs whenever there is coincidence between the generated time code and the stored start-time and end-time codes, respectively, and a conditioning circuit for conditioning the power switch in response to the first and second coincidence outputs, so that the power switch is enabled and disabled, respectively, following the occurrence of the start and end times when the outputs of the timing circuit and the first memory coincide, a second coincidence detector for detecting the coincidence of the

Abstract: An indicator is responsive to a gain control voltage applied to an amplifier for indicating the gain of the amplifier irrespective of amplitude of the signal being amplified. The amplifier may be an audio amplifier in a television receiver which also contains an electronic tuner tuned by a tuning voltage, in which case, the indicator may alternatively indicate the tuning voltage while a television channel is being preset and the gain of the audio amplifier at other times.
