Abstract: PURPOSE:To enable to correct the fuel increasing and decreasing rate always appropriately in an internal-combustion engine in which the reference fuel injection rate is corrected according to the operational conditions of the engine, by making the recovery speed of a correction factor after it is decreased at the time of deceleration lower than the attenuation speed of the correction factor after it is increased at the time of acceleration. CONSTITUTION:In controlling an injection valve 30 by determining a datum fuel injection rate from a signal relating to the pressure in an intake pipe, given from a sensor 23 for detecting the pressure in the intake pipe, and an engine-speed signal given from a crank angle sensor 44 in a control circuit 54, fuel supply rate is increased at the time of acceleration by use of a correction factor that is increased according to the speed, detected by a throttle sensor 20, at which the opening of a throttle valve 18 is increased. The above correction factor is attenuated to zero at a prescribed attenuation speed. At the time of deceleration, on the other hand, fuel supply rate is decreased similarly by use of the correction factor that is decreased according to the speed at which the the opening of the throttle valve 18 is decreased, and the correction factor is recovered to zero at a prescribed speed. Here, the recovery speed is selected to be lower than said attenuation speed.

IPC: H04B1/16
Filed: 1985-02-15
Abstract: PURPOSE:To suppress the consumption of a battery to the minimum, and also to confirm the time at the time of necessity by constituting a titled radio receiver so that the time is displayed only for a prescribed time at the time of the operation of a specified switch. CONSTITUTION:A titled radio receiver is constituted so that the power source of a display driver 15 is not supplied from the power source supply path of a radio by a relay 23 but is supplied from a display system power source supply path by a relay 24. When Recall SW is turned on, a display power source port R2 of a controller 12 becomes 'H' for a prescribed time (for instance, 5sec), and the relay 24 becomes on. At the same time, the controller 12 sets a clock display data to an output buffer, etc., and gives it to the display driver 15. As a result, when 5sec elapse, the controller 12 sets the display power source port R2 to 'L' and turns off the relay 24, and simultaneously, brings the data in the output buffer to blanking.

Title: Resistance seam welding machine
Inventor: FUJIOKA TADASHI
IPC: B23K11/06
Filed: 1989-02-09
Abstract: PURPOSE:To exactly detect the position of an anchor piece and to maintain continuity of nuggets by providing a micro displacement gage to detect micro displacement between a couple of arms for traveling wheels between the arms. CONSTITUTION:When the traveling wheels 3a and 3b are rotated and a welding machine main body is made to travel, flat folding part 11 is subjected to resistance seam welding by an electrode ring. When the traveling wheels 3a and 3b approach the anchor piece, the arms 17a and 17b for the traveling wheels are opened slightly as the thickness of the flat folding part 11 is changed. This movement appears as displacement of a cantilever 24 in contact with a stator 27 elastically at all times via a contactor 25 and the electric output is changed by a strain gage 23. By this method, since the position of the anchor piece 12 is detected exactly, its detected signal is sent to a welding controller and the nuggets at an inlet and an outlet of the anchor piece 12 are continued with the prescribed width.

Title: Coiled wave spring and its manufacture
Inventor: SHIBUYA MINORU
IPC: F16F1/02
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To provide a compact spring which has a characteristic of small friction. SOLUTION: A coiled wave spring is prepared by winding a corrugated wire. The superposed tops and bottoms of the spring abut each other. Specified clearances are formed at tapered portions between the tops and bottoms. The first winding of the spring, that is, an upper loop 1 abut the second winding, that is, a lower loop 2 only at their tops and bottoms. Clearances are formed between the windings at their tapered portions. When the spring receives a load and is deformed, the above-mentioned tops and bottoms are in contact with each other causing little friction. The clearances are formed between the windings, so that no friction is generated here.
