A solid polymer electrolyte membrane fuel cell electrode catalyst layer comprises Pt particles carried on a carbon carrier and a solid polymer electrolyte, wherein a center-to-center distance dimension (Lpt−pt) between the Pt particles carried on the carbon carrier is made to substantially coincide with the sum of a double of a total dimension resulting by adding the length (Lpes) of a side chain having an ion-exchange group to the diameter (Dpem) of a main chain of the solid polymer electrolyte and the diameter (Dpt) of the Pt particle.

An indicating instrument includes a dial plate, a casing disposed behind the dial plate, a drive control section disposed in the casing and a rotary shaft driven by the drive control section. The rotary shaft is comprised of a pair of thin shafts respectively supported by a pair of bearings and a thick shaft connecting the pair of thin shafts. Each thin shaft has such a length and an outside diameter that the ratio of the length to the outside diameter provides a sufficient bending strength. Therefore, the rotary shaft rotates smoothly and a pointer carried by the shaft indicates accurate values of a vehicle operating condition.

A fuel cell stack has a plurality of fuel cells, separators sandwiching each of the fuel cells, and first and second end plates disposed on respective opposite ends of the plurality of fuel cells. A fastening structure incorporated in the fuel cell stack has a liquid chamber disposed on an outer surface of the first end plate, a silicone oil filled in the liquid chamber, and a pressurizing mechanism disposed on an outer surface of the second end plate, for pressing the fuel cells toward the first end plate. The plurality of fuel cells is given a uniform surface pressure, and can be reduced in weight and made compact.

Disclosed is a fuel cell system and a draining method for the same based on the use of a reformer, a fuel cell, a methanol tank for storing methanol, a water recovery tank for storing water discharged, for example, from the fuel cell, an aqueous methanol solution tank for mixing methanol and water, and a changeover valve connected under the water recovery tank and capable of draining all of water contained in the water recovery tank and a water passage. Accordingly, no water remains and freezes in the fuel cell system when the system is stopped. It is possible to reliably start the system, and it is possible to improve the reliability.
摘要:
A data processing system which executes pipeline processing that decodes a subsequent instruction in an execute phase of a current instruction in response to a clock signal. The data processing system includes a CPU and a mode management block. The CPU supplies an address bus with at least one predetermined address in an execute phase of a clock supply stop instruction. The mode management block produces a clock stop signal if the predetermined address agrees with a self-address assigned to the management block in advance, thereby halting the supply of the clock signal. This makes it possible to solve a problem of a conventional data processing system in that it executes the instruction next to the clock supply stop instruction in spite of execution of the clock supply stop instruction because the clock stop signal is actually output when the clock supply stop instruction shifts from the execute phase to the write back phase, in which case the next instruction proceeds in the execute phase.

A device for measuring concentration of a constituent in blood includes: an irradiation unit for irradiating light toward a living body, the light having a wavelength disposed in a light absorption band of the constituent in the blood; a light receiving unit for receiving light, which is reflected in the living body or transmitted through the living body; and a concentration measurement unit for measuring the concentration of the constituent in the blood based on variation of light intensity of light received by the light receiving unit, the variation attributed to a pulse wave of the living body.

A meter unit for indicating a physical quantity includes an indication part and a control part. The indication part memorizes a first indication deviation data, which provides a deviation between a detected value detected by a physical quantity sensor and a raw value indicated by the indication part without compensating the deviation. The control part memorizes a second indication deviation data, compensates the detected value on the basis of the second indication deviation data, and controls the indication part on the basis of the compensated detected value. The second indication deviation data is rewritable so that the second indication deviation data coincides with the first indication deviation data.

A speed meter unit has a magnetic pointer position detector, including an output coil, a detection coil and a magnetic piece. The output coil generates magnetic flux. The detection coil is for detecting the magnetic flux from the output coil. When a pointer has returned to an initial position, the magnetic flux generated in the output coil can reach the detection coil through the magnetic piece, so that a microcomputer can detect the initial position of the pointer. Such the magnetic pointer position detector is resistive to the soil or the oxidization, so that the speed meter unit can detect the initial position of the pointer accurately and securely.

A meter such as a speedometer for use in an automobile instrument panel includes a pointer driven by a stepping motor. A pulse voltage having a wider pulse width is supplied to the stepping motor to obtain a higher induced voltage to be compared with a threshold voltage for detecting the pointer-zero-position. After the pointer-zero-position is detected, the stepping motor is driven by a pulse voltage having a narrower pulse width to obtain a quicker response of the pointer. In this manner, the pointer-zero-position is accurately adjusted without sacrificing the quick response of the meter pointer.
