A fuel cell system includes an anode electrode to which fuel is to be supplied; a cathode electrode to which an oxidant containing air or oxygen is to be supplied; an electrolyte membrane disposed between the anode electrode and the cathode electrode; a catalyst section configured to accelerate a chemical reaction of at least a portion of a material discharged from the cathode electrode and a material discharged from the anode electrode; an oxidant supply unit configured to supply the oxidant to the cathode electrode; and a control unit configured to control an amount of the oxidant to be supplied to the cathode electrode. The control unit controls the oxidant supply unit to increase the amount of the oxidant to be supplied to the cathode electrode when the oxidant supply unit starts to operate.

An electronic device has an operating panel. A through-hole penetrating the operating panel is provided at a part of the operating panel. A partition board includes a board part and a partition part, and a step is provided between the board part and the partition part. In an area where the through-hole and the board part of the partition board are to be formed, a metal mold can be thickened. In an area where a narrow gap on a surface side of the operating panel is to be formed, the length of the metal mold can be reduced. Therefore, the strength of the metal mold can be maintained. Also, the step of the partition board, which separates the board part and the partition part, prevents visual recognition of the through-hole by a user.

An engine unit includes a valve driving mechanism in which a cam having its cam profile axially varying continuously is slid along the axis of the cam shaft to control continuously a lift characteristic of an intake valve to be steplessly variable. In the control device of the engine, when the engine is, determined to be in a idling state by an idling-state determining unit, a target cam position is obtained according to a target valve lift amount calculated based on the cooling water temperature by a target cam position calculated unit, and the target cam position is corrected according to atmospheric pressure, an engine oil temperature, an ATF temperature, and an intake temperature, so that an engine rotation will be stabilized in the idling state.

It is desired to adopt gamut mapping using a color appearance space in the processing system of an ICC profile. Upon generating an LUT complying with the ICC profile format, when CIEL*a*b* values are converted into CIEXYZ values, and the XYZ values are converted into color appearance space values using color appearance conversion formulas, a point which can be converted and becomes a nearest neighboring point for a point that satisfies a predetermined condition is retrieved, and corresponding color appearance space values are calculated. The obtained color appearance space values are mapped on a predetermined device gamut.

A method of manufacturing a positive electrode foil of an aluminum electrolytic capacitor is provided in which anodizing conditions are optimally determined and automatically set to minimize the loss of production and to produce a constant quality of the positive electrode foil. The method comprises an etching process and an anodizing process. An etched foil produced in the etching process is subjected to a constant current inspection, and then, the anodizing conditions are determined from the result of the constant current inspection. The anodizing conditions are transferred to a control panel in the anodizing process where they are automatically registered as its settings. Also, an apparatus for manufacturing the positive electrode foil is provided which has a voltage sensor connected between an output running roller and cathode electrodes in an anodizing tank. A voltage measured by the voltage sensor is fed back to a direct-current source for controlling its output voltage.

A plug hole pipe 79 has thread grooves 81 formed on an outer circumferential surface thereof and causes a spark plug 11 to be pressed against a cylinder head 51 when the plug hole pipe is fixedly attached to the cylinder head 51 through screw engagement. The spark plug 11 is configured such that no thread grooves are formed on the outer circumferential surface of a front end portion 25 of a metallic shell 19, and can be vertically inserted into a plug disposition hole 51a formed in the cylinder head 51. By vertically inserting the spark plug 11 into the plug disposition hole 51a while the orientation of a ground electrode 21 is set beforehand in relation to the cylinder head 51, the ground electrode 21 can be oriented in a specific direction.

When an electric appliance unit functions as an electric motor, a rotary shaft is rotated by electric current supplied to the electric appliance unit. When the electric appliance unit functions as a generator, the generator generates electricity as the rotary shaft rotates. A first rotation permitting mechanism is located between the rotor and the rotary shaft to permit the rotor and the rotary shaft to rotate relative to each other. A one-way clutch is located between the rotor and the rotary shaft. The one-way clutch permits the rotary shaft to rotate in one direction relative to the rotor and prevents the rotary shaft from rotating in the other direction relative to the rotor. A second rotation permitting mechanism is located between the housing and the rotor. The second rotation permitting mechanism permits the rotor to rotate relative to the housing. Power transmitted from the external drive source to the rotor is transmitted to the rotary shaft via the one-way clutch. The rotor is supported by the housing with the second rotation permitting mechanism.

A pressure sensor-incorporating spark plug including a groove 17e for accommodating an output cable 27 formed on a side surface of a hexagonal portion 17a. A U-shaped member is bent into a tubular shape to obtain a fixing member 31. After the fixing member 31 and the output cable 27 passing through the fixing member 31 are placed in the groove 17e, the fixing member 31 is crimped in the direction of the arrow shown in FIG. 5(a), so that the fixing member 31 is deformed to fit the wall surface of the groove 17e. Thus, the output cable 27 is nipped by the fixing member 31, and the fixing member 31 is held within the groove 17e of the hexagonal portion 17a. As a result, the output cable 27 is fixed to the hexagonal portion 17a.
