Abstract: A heat pump and hydrogen compression apparatus includes a heat exchange chamber through which a heating medium source circulates, a pair of hydrogen chambers formed on both sides of the heat exchange chamber, and hydrogen storage alloy pipe groups, one end portion of which imports into the pair of hydrogen chambers, and whose other end portion extends in a free state into the heat exchange chamber, and that form a pair whose one end portions that are on the side of the pair of hydrogen chambers are each fixed on that side, wherein the hydrogen storage alloy pipe groups have hydrogen storage alloy pipes provided a hydrogen storage alloy inside, the free end portion on the heat exchange chamber side of the hydrogen storage alloy pipe is closed off, and hydrogen circulation holes are opened in the end portions on the hydrogen chamber sides of the hydrogen storage alloy pipe.

Abstract: A protective member, which covers a sensor portion, is positioned on a slider so that this sensor portion is in close proximity to the slider flying surface. Furthermore, a step is formed on the surface of this slider on the side opposite the flying surface at a location separated from the protective member. Then, an actuator is either mounted on the flat portion which was made thin by the formation of the step, or an actuator is stored and affixed within a slot created in line with the formation of the step. Furthermore, a suspension is bonded to a surface of this actuator on the side opposite the slider, and a head assembly is configured.

Abstract: The present invention provides a thermoelectric conversion apparatus having a thermoelectric conversion module and a temperature restoration module. The thermoelectric conversion module comprises hydrogen storage and release devices provided with circulating heating medium changeover valves and containers in which are formed inside a plate cassette laminate or a pipe aggregate provided with a hydrogen storage alloy in the form of a thin film on the outer surfaces of the plate cassettes or pipes, a pump device for an working liquid provided with a liquid piston, an electronic control device that controls the changeover valves, and an electric power generation device that converts the flowing force of the actuator liquid into electricity.
