Title: Control device of idling revolution in engine
Inventor: UEDA CHIYUUICHI
IPC: F02D31/00
Filed: 1981-10-09
Abstract: PURPOSE:To prevent an engine from overshooting by increasing the amount of suction air gradually when the number of revolutions of the engine is over the first fixed value but lowered under the second fixed value. CONSTITUTION:In an idling state where a throttle valve 7 is at an idling position and a number of revolutions N of an engine is under a fixed value, a CPU 22c obtains a target number of idling revolutions NSET in accordance with a temperature of cooling water and a load of a cooler, and a temporary target throttle opening T1. Then, the first correction term of a target throttle opening T2=(NSET-N) and the second correction term T3 to correct a rapid lowering  of revolutions are calculated for obtaining the target throttle opening TSET= T1+T2+T3. When the number of revolutions N is under the first fixed number  of revolutions Ne, T3 is selected as the first fixed amount T3'. When N is over  Ne and under the second fixed number of revolutions Nm, the second fixed  amount T3'' is added, that is, a calculation is successively carried on as T3= T3'+T3''+.... This construction permits to prevent the engine from overshooting  or stopping.

Abstract: PURPOSE:To provide a DC gas discharge type display device adapted to be driven with a pulse-memory system, which gives a practical level of luminescence brightness with small cell pitches, has a sufficient pixel density for OA and exhibits a high luminescence brightness. CONSTITUTION:Grouped cathode members 2 are disposed on a rear panel 1 and intra- cathode spaces are sectioned by long-sized partition-wall strips 3 to provide discharge spaces. Further, several mutually adjoining cathode members of the grouped cathode members 2 are collectively regarded as one block, and a block partition wall 4 is installed, in parallel with the cathode members, between each two adjacent of the blocks. On the partition-wall strip group 3 there is adhered a glass plate 7 on which grouped anodes 5 and fluorescent materials 6 are coated and burned, so that the anodes 5 and cathode members 2 may oppose while intersecting each other at right angle, whereby the glass plate 7 is hermetically sealed with respect to the strip group 3. Scanning of the cathode members is not sequentially performed, but is conducted so that simultaneous discharge may not occur in two or more discharge spaces each having a cathode member included in the same block. By so doing, a panel with small cell pitches necessary for OA has a high luminescence brightness and has no display error.

Abstract: PURPOSE:To attain a short-time stop of a traveling object such as a rotary shaft, etc., by delivering a low speed command after a switch of position control and giving stop control to the traveling object by a position deviation signal after moving the traveling object when the traveling object is positioned with speed and position controls. CONSTITUTION:A main shaft mechanism 6 attached with a tool 8 is driven by a DC motor 4 via a gear 9 of a main shaft 7. When a switch SW1 is closed, a speed command CV given from a speed command circuit 1 and a real speed AV given from a rotary speedometer 5 are supplied to an adder 3a. Then the speed deviation voltage is delivered. The firing angle of a thyristor circuit 3d is controlled by a voltage/phase converter 3c in response to said deviation voltage. Thus the voltage to be applied to the motor 4 is increased and decreased to control the speed AV of the motor to obtain coincidence with the speed CV. When the cutting work is over, an orientation command ORCM is supplied to the circuit 1 from a constant position command circuit 2. At the same time, the command CV is set at 0 to set the speed AV at 0. Then a switch circuit 11C opens and closes switches SW1 and SW2 to perform position control.

Title: Air conditioner
Inventor: MIYATA KENJI
IPC: F25B1/00
Filed: 1989-06-23
Abstract: PURPOSE:To improve an actuation of a compressor in an air conditioner for communicating a discharged side with a suction side and making a uniform pressure when the compressor is stopped by a method wherein a gas line between a condensor of an outdoor device and a closing valve is provided with a liquid-gas separator. CONSTITUTION:When a compressor 1 is stopped, its discharged side and its suction side are uniformed in their pressures by a uniform pressure pipe 1c, resulting in that a motor load ot the compressor 1 when energized is reduced. In this case, bubbles are generated in the liquid refrigerant due to a rapid reduction of high pressure, its volume is increased and even if the liquid refrigerant within. the condensor 12 or a liquid receiver 13 of the outdoor device B is apt to move toward the compressor 1, the liquid refrigerant is stopped by a gas-liquid separator 18 in the gas line 22b between a gas side closing valve 15 and the condensor 12 so as to prevent the liquid refrigerant from being accumulated at the discharging side ot the compressor 1. Accordingly, a closing caused by an accumulation of the liquid refrigerant of the oil separator 2 is prevented and the liquid refrigerant accumulated at the discharged side is heated by the hot discharged gas from the compressor 1 and the compressor 1 is prevented from being over-loaded due to a rapid increasing of pressure and further the compressor can be positively energized.
