Abstract: A welding jig for holding a motorcycle fuel tank when the fuel tank is welded includes a plurality of attachments for holding said fuel tank through resilient bodies. The plurality of attachments have springs hold the outer plate of a fuel tank, and an inner jig positions an inner plate. The attachments are attached to clamp arms which are opened/closed by cylinders. When the overlap portion between the outer and inner plates is welded, the thermal deformation caused by welding is accommodated by the springs. The attachments are spaced from the fuel tank in the order in which the welding point is approached.

Abstract: A fuel cell separator is provided which has in a peripheral part (30) gas passages (31, 31) for guiding reaction gases and reaction product passages (33) for guiding a reaction product. The separator (20) is made up of a central part (22) made of metal, a peripheral part (30) made of a resin material, and an elastic member (40) connecting the central part and the peripheral part together. As a result of the peripheral part being made of a resin material, the gas passages and product passages are resistant to corrosion.

Abstract: A fuel cell stack 1 in a fuel-circulating fuel cell system is supplied with fuel and an oxidizing agent to generate electricity. The fuel discharged from the fuel cell stack 1 is supplied to the fuel cell stack 1 again through a fuel-circulating passage 6. In the fuel-circulating passage 6 is provided a fuel pump 3 powered from an outside source to circulate the fuel through the fuel-circulating passage 6 at a predetermined circulation rate. An ECU 4 transmits an output instruction value to the fuel cell stack 1 and regulates a circulation rate of the fuel in the fuel-circulating passage 6 according to the output instruction value.

Abstract: An element such as Cr is caused to dissolve sufficiently in a base-material metal (Cu) in a solid solution state at a high temperature and a material in a supersaturated condition is obtained by performing quenching. After that, a strain is applied to this material and this material is subjected to aging treatment at a low temperature simultaneously with or after the application of this strain. As a result of this, it is possible to obtain a copper alloy having properties desirable as an electrode material, for example, a hardness of not less than 30 HRB, an electrical conductivity of not less than 85 IACS %, and a thermal conductivity of not less than 350 W/(m·K).

Abstract: A genetic design method and apparatus in which desired profiles, such as of an automobile, are broken down into concepts, including the local concepts of surface segments and glue segments, and in which a genetic algorithm is used to evolve parent profiles to produce offspring profiles based on merit values of the concepts. The genetic algorithm includes a probabilistic recombination algorithm which selects for each of the attributes of the concepts at least one of a random value and a value of the attribute associated with one of the parent profiles depending on a non-linear importance function based on the merit values. The combination of the merit values, as represented by the non-linear importance function, reflects the preferences of the designer as the design progresses through various modifications and generations of evolution. A family tree is maintained to identify successive generations of the parent and offspring profiles.

Abstract: A control device for a hybrid vehicle prevents a decrease in the total amount of regenerated energy in the entire vehicle while ensuring the stability of the vehicle when the vehicle decelerates. When the vehicle decelerates and regenerated energy is recovered by the regeneration operation of front motor and rear motor, the ECU sets the amount of regeneration, which is transferred from front wheels to rear wheels, depending on the steered angle of the front wheels and on the deceleration state of the vehicle. In addition, the ECU subtracts the amount of regeneration to be transferred from regeneration torque command value for rear wheels demanding from the rear motor, and adds the same amount of regeneration to regeneration torque command value for front wheels demanding from the front motor.

Abstract: A reference electrode is provided adjacent to an anode of a membrane electrode assembly. The potential difference between the reference electrode and the anode is measured by a control unit. The control unit compares the measured value and a map of the anode potential difference stored in the control unit. When the measured value indicates a relation line which is different from a reference line indicating that the fuel gas is sufficient, it is judged that shortage of the fuel gas occurs.

The parts table database includes a parts list which stores a state data and a part number data. The state data indicates a progress state of a part. And the part number data includes a number of the part as an identifier. The parts list controller inhibits change of the part number data, when the state data indicates prohibition of the change of the part number data.

Abstract: An object of the present invention is to provide a three-dimensional CAD-system for adding data about a drafting direction of a die to three-dimensional data about the part to be formed by that die, and a cost calculation system for calculating the cost of the part based on that drafting direction data. A three-dimensional model generation unit of a CAD system generates: a three-dimensional shaped model of a given part based on information coming from an input operation unit. A drafting direction data setting unit establishes drafting direction data when the input operation unit is operated to designate the drafting direction of the die for press molding, injection molding or the like of the part in question. A projected area calculation unit calculates a projected area S of the part on a plane perpendicular to the drafting direction of the applicable die on the basis of the three-dimensional model of that part and the drafting direction data involved.
