摘要:
A fuel cell system which prevents the deterioration of the fuel cell stack when feeding of the oxidant gas is paused under a load to perform a fuel conservation operation. Controller shuts down oxidant gas compressor and cooling water circulating pump to execute fuel conservation operation at a low fuel cell system load. The controller gives a current draw instruction to electric power controller. In the fuel conservation operation, electric power controller draws a current larger than zero from fuel cell stack, and keeps the total charge drawn per unit time constant or substantially constant.

This adhesive for electroless plating can be produced without causing dust explosion and is excellent as an interlaminar resin insulating layer and is obtained by mixing an organic solvent dispersion of cured particles of heat resistant resin soluble or decomposable in an acid or an oxidizing agent with an uncured resin. The dispersion of the cured particles of the heat resistant resin in the organic solvent is obtained by dispersing cured particles formed in the production of heat resistant resin cured particles into the organic solvent without drying, and the uncured resin is a resin becoming hardly soluble in an acid or an oxidizing agent through curing treatment and capable of forming a heat resistant cured resin.

There is provided a data processing device able to surely eject a recording medium out of a main body of the device even when the recording medium is received in a case while a locking member having adherence and elasticity of the case is locked with a center hole of the recording medium.A CD player includes: a main body of the device 3; a carrying unit 5 for ejecting and retracting a CD 2 from the main body of the device 3; a clamping and reading out unit 6 for reading out data recorded on the CD 2; and a microcomputer 4. The carrying unit 5 includes: a disc guide 17; and a roller arm 18 having a carrying roller 20. The microcomputer 4 makes the turntable 26 of the clamping and reading out unit 6 rotate while the CD 2 is held between the disc guide 17 and the carrying roller 20 when the carrying unit 5 fails to eject the CD 2 out of the main body of the device 3.

A terminal joining structure includes a terminal having a tubular barrel portion and a flange portion that is integrally formed at the axis-direction end of the barrel portion, a conductor substrate on which is opened a through-hole for inserting the barrel portion, and a ring that fits on the barrel portion on the opposite side of the conductor substrate. On the barrel portion is formed a taper that increases in diameter toward the flange portion. The diameter of the larger-diameter portion of the taper is larger than the inner diameter of the through-hole. The terminal is caulked to cause radially outward expansion of an end part of the barrel portion, which passes through the ring, on the opposite side of the conductor substrate and is fixed to the conductor substrate together with the ring.
