摘要:
A first step where a computer performs press forming analysis based on a shape of a formed product or a shape of a member, a blank holder force, a friction coefficient, a tensile strength of a material, a yield strength, a stress-strain relation, and a sheet thickness, as press forming conditions, to calculate sheet thickness distribution and post-formation strain distribution of the formed product; and a second step where the computer performs performance analysis based on the sheet thickness distribution, the post-formation strain distribution, and the shape of the formed product or the shape of the member, as state amounts of the formed product, to calculate performance of the member are included, in which the computer repeats the calculations performed in the process from the first step through the second step a predetermined number of times, with at least one of the press forming conditions being changed, to output an optimum press forming condition that gives a maximum value or a target value of the performance.

A membrane electrode assembly is constituted of a solid electrolyte membrane 1 made of a polymeric material, and a fuel electrode 2 and an air electrode 3 which are disposed on both sides of the solid electrolyte membrane 1. A porous membrane 8 is attached to the back surface of the fuel electrode 2, and a fuel tank 12 is formed between a casing 16 of the fuel electrode 2 side and the porous membrane 8. The fuel tank 12 is filled with liquid-retaining sheets 14. An air chamber 13 is formed on the back surface of the air electrode 3, and the air chamber 13 is filled with moisture-retaining sheets 15. A casing 17 of the air electrode 3 side is provided with a number of inlet ports 21. Further, fins 22 are formed on an outer surface of the casing 17 of the air electrode side.

The control apparatus for a movable robot comprises: environment information acquisition means (such as video camera 3 and microphone 4); a current position detecting means (15); a map storage (7); a control parameter storage (9) for storing control parameters adjusted to different environments; and control means (11, 12) for determining a current position of the robot on the map data based on a signal from the current position detecting means, retrieving control parameters suitable for the current position from the parameter storage, and controlling the environment information acquisition means or actuators for moving the robot by using the retrieved control parameters.
摘要:
When neither recording nor replaying of information upon a hard disk recording medium is being performed, empty regions are searched for upon said hard disk recording medium; and, also when neither recording nor replaying of information upon said hard disk recording medium is being performed, said empty regions which have been found are monitored.

A remote controller for a biped robot is of a simple arrangement capable of remotely controlling movement of the biped robot while taking into account the stability of the attitude of the robot. A manipulation unit 23 outputs, to a robot A, signals representative of manipulated positions of manipulator levers 26, 26 which correspond respectively to both legs 2, 2 of the robot A. A control unit 19 mounted in the robot A generates a motion command (desired gait) for determining motions of the legs for at least two steps of a walking action of the robot A depending on the manipulated positions of manipulator levers 26, 26 which are represented by output signal data from the manipulation unit 23, and controls motions of the legs 2, 2 based on the motion command.

摘要:
In a vehicle seat containing an airbag apparatus in a seat back, a cover member for covering a side portion storing the airbag apparatus is constituted by a plurality of cover elements. The cover elements are made of material having different elongation percentages in a length direction and a width direction and sewn together to constitute the cover member. The cover element located on a front surface of the side portion is obtained by cutting the material such that the less extendible direction corresponds to a width direction of the seat back, and the cover element located on a side surface of the side portion is obtained by cutting the material such that the less extendible direction corresponds to a back-forth direction of the seat back. The cover elements are sewn together in a sewing portion extending in a vertical direction. The sewing portion is cut, when the airbag is expanded.
摘要:
Disclosed is an acidic cleaning aqueous solution for aluminum and aluminum alloy and a process for cleaning the same, intended to execute acidic cleaning without using harmful fluoride and chloride ions.The oxidation-reduction potential of a cleaning bath is controlled to be at 0.5 to 0.8 V (vs. Ag-AgCl). The cleaning bath is obtained by diluting an acidic cleaning aqueous solution for aluminum and aluminum alloy to a predetermined volume. The acidic cleaning aqueous solution contains specified amounts of at least one of inorganic acids, Br.sup.- ions and oxidized metal ions, with the addition of a surfactant and oxidizing agent if necessary.It is thus possible to present a uniform etching effect irrespective of low temperature (below 60.degree. C.) without containing fluoride ions and chromic ions within the acidic cleaning aqueous solution. Br.sup.- also has an effect of inhibiting the oxidation-decomposition reaction of the surfactant arising from the oxidizing agent and oxidized metal ions, thereby obtaining a long-life acidic cleaning aqueous solution.
