Abstract: A fuel cell system supplies a reacting solution from a liquid storage section to a reaction section to generate a reacting gas. A gas storage section stores the reacting gas and supplies it to a solid polymer membrane fuel cell which generates electricity using the reacting gas as fuel. The reacting solution is supplied from the liquid storage section to the reaction section when the pressure in the liquid storage section is higher than the pressure in the reaction section and the supply of reacting solution is stopped when the pressure in the liquid storage section is lower than the pressure in the reaction section. In this manner, the supply volume of the reacting solution is controlled in accordance with the driving state of the fuel cell.

Abstract: An electric equipment has a battery and an electric condenser that has an internal resistance lower than that of the battery and accumulates therein an electric power of the battery. A charge control circuit controls a charge current originating from the electric power of the battery and flowing from the battery to the electric condenser. The charge control circuit controls the charge current in accordance with a self-discharge rate of the battery. A load is driven with the electric power accumulated in the electric condenser.

Abstract: A fuel cell system comprises a liquid storage section for storing a reacting solution, a reacting section for generating reacting gas from the reacting solution, a gas storage section for storing the reacting gas supplied from the reacting section, and a fuel cell for generating electricity while the reacting gas is being used as fuel. A reacting solution supply volume adjusting device supplies the reacting solution from the liquid storage section to the reacting section when the pressure in the liquid storage section is higher than the pressure in the reacting section and stops the supply of the reacting solution when the pressure in the liquid storage section is lower than the pressure in the reacting section.

The electronic equipment includes: a first battery such as a battery or a secondary battery, having a high internal resistance; an electric condenser having an internal resistance lower than that of the first battery for accumulating therein an electric power of the first battery; a charge control circuit for controlling a charge current, for the electric condenser, originating from the electric power of the first battery; and a load driven with the accumulated electric power of the electric condenser.

Abstract: A structural body material layer is formed directly on a base substrate or via a sacrificing layer or a peeling layer, a groove is fabricated electrochemically along an outer configuration shape of a part constituting an object at the structural body material layer and thereafter, only the sacrificing layer or the base substrate is selectively removed or the part is mechanically separated from the peeling layer to thereby separate the part and the base substrate and provide the part constituting the object or fabricate a part having a movable portion by partially restricting a portion to be separated.

Abstract: A pump comprises a first substrate having a fluid inlet port for receiving a fluid, a fluid outlet port for discharging the fluid, a first pumping section for pumping the fluid from the fluid inlet port to the fluid outlet port, a first inlet valve section disposed between the fluid inlet port and the first pumping section, and a first outlet valve section disposed between the fluid outlet port and the first pumping section. A second substrate has a second pumping section, a second inlet valve section, and a second outlet valve section. An intermediate substrate is disposed between the first and second substrates to form a first fluid feeding path and a second fluid feeding path for feeding the fluid pumped by the first and second pumping sections. The first fluid feeding path extends from the first inlet valve section to the first outlet valve section through the first pumping section.

Abstract: A micropump comprises a first substrate, a pumping section formed in the first substrate, a second substrate connected to the first substrate and having an inlet port and an outlet port, and at least two valve sections formed in the first substrate for controlling the flow of fluid from the inlet port to the outlet port through the pumping section. The pumping section has a piezoelectric element and a diaphragm for undergoing deformation upon application of a voltage to the piezoelectric element to control the flow of fluid into and out of the pumping section. Each of the valve sections has a piezoelectric element and a diaphragm for undergoing deformation upon application of a voltage to the piezoelectric element. A flow passage is formed in the first substrate for connecting the pumping section and the valve sections in fluid communication.

Abstract: An actuator comprises a base, a guide assembly mounted on the base, a first displacing unit mounted on the base for displacement into engagement with the guide assembly to place the first displacing unit in a fixed state and for displacement in a moving direction along the guide assembly when the first displacing unit is not in a fixed state, and a second displacing unit integrally connected to the first displacing unit and mounted on the base for displacement in the moving direction along the guide assembly. A holder is mounted in contact with the guide assembly for movement with the second displacing unit and for supporting the second displacing unit on the guide assembly with a frictional force weaker than a force with which the first displacing unit is maintained in the fixed state to thereby allow the second displacing unit and the holder to move in the moving direction while the holder contacts the guide assembly and while the first displacing unit is in the fixed state.

Abstract: A method of correcting a missing defect of a patterned film formed on an icle is carried out by steps of providing an operative vacuum chamber having a pin hole, positioning an area of the missing defect outside the vacuum chamber in registration with the pin hole, operating the vacuum chamber to cause therein cold cathode discharging to generate particles, and directing a stream of the particles through the pin hole onto the area of the missing defect to deposit thereon a corrective film of the particles.
