Title: Fuel injection quantity control device for internal combustion engine
Inventor: HIYOUDOU YOSHIHIKO
IPC: F02D41/04
Filed: 1988-05-02
Abstract: PURPOSE:To optimally control the fuel injection quantity at the time of accelerating the engine speed by calculating a fuel injection lag time relative to a fuel injection time determined by the air volume and the engine speed of an internal combustion engine based on a time lag element whose magnitude corresponds to the difference between a target air-fuel ratio and an air fuel ratio of the engine. CONSTITUTION:The air volume passing through the upstream side of a throttle valve is detected by a sensor A. An engine speed is then detected by a sensor B, and an air fuel ratio is detected by a sensor C. On the other hand, a time lag factor whose magnitude corresponds to the difference between the air fuel ratio detected by the sensor C and a target air-fuel ratio is calculated by a means D. Further, a fuel injection time relative to the fuel injection time determined by the air volume and the engine speed respectively detected by each sensor B, D is calculated by a means E based on the time lag factor calculated by the means D. The fuel injection quantity is then controlled by a means F based on the fuel injection lag time calculated by the means E. The fuel injection quantity at the time of accelerating the engine speed is thus optimally controlled regardless of the variation, etc., in the operation of a fuel injection valve.

Title: Chair for theater hall
Inventor: SAKAI TAKESHI
IPC: A47C7/62
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To control reverberation characteristic by joining a film to an external woven fabric covering the cushion body of a chair, thereby adjusting sound absorption characteristic such as the frequency characteristic of sound absorption power, the degree of the sound absorption power. SOLUTION: Only the sound absorption power of high compass can be reduced with the reduction of the thickness of a film, and the sound absorption power of low compass can be reduced with the increase of the thickness of the film. At the time of joining the thin film 18 to a wide area, the sound absorption power of a medium and high compass can be reduced larger. When joining the thick film 18 to a narrow area, the sound absorption power of a low compass can be reduced larger, and at the time of joining the thick film 18 to a wide area, the sound absorption power can be reduced in whole compass.  For example, by using polyurethane foam as the respective cushions 15, 16 of a back and a seat, a vinyl chloride film 18 of 70 μm thickness is force-fitted to both of the right and left side surfaces of an woven fabric 17 covering the seat cushion 16 through the use of an adhesive and the film 18 is joined to an area equal to or larger than about 30% of the total area of the fabric 17. Thus, a chair 10 for a small theater hall having small sound absorption power over the whole compass of 125 Hz to 4 kHz is obtained.

Title: Robot control device
Inventor: KAMIYA KOJI
IPC: B25J9/18
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To perform regulation of a press reaction force when a work to press a work against a designated surface is carried out and to eliminate a fear of a press reaction force being excessively increased, in a robot. SOLUTION: When the press reaction force of a robot tip detected by a press reaction force detecting part 18 exceeds given magnitude, a position correction amount corresponding to the press reaction force is computed by an impedance correction track calculation part 20 and added to a target position given by a position track production part 11. Thereby, since the robot tip is moved in a direction in which the press reaction forced is decreased, a robot provides flexibility following the press reaction force. When the press reaction force of the robot tip is too increased due to some cause, a switch element 22 is closed and a switch element 23 effect change-over operation, and the virtual position of the robot tip is determined by a deceleration stop position calculating part 24 such that the press reaction force forms a set limit value.  Since the virtual position forms a target position, the press reaction force exerted on the robot tip is controlled to a preset limit value.
