Abstract: PURPOSE:To carry out a duty correction apart from the compensation of a spark advance on the sudden change of a car speed so as to improve the responsibility of the control of a constant speed, by adding a corrected duty which increases with a passed time to an output duty when an acceleration exceeds a prescribed value. CONSTITUTION:An acceleration DELTAV is calculated by differentiating a traveling car speed Vn which is obtained from a car speed signal through a car speed filter, and a spark advance car speed Vs is calculated by adding the acceleration DELTAV to the traveling car speed Vn. And the control valve of an actuator adjusting the opening of a throttle is on-off controlled by an output duty D which is obtained from the conversion characteristics of the spark advance car speed Vs and a duty, and a real traveling car speed Vn is approached to a stored target car speed VM. In this case, whether the acceleration DELTAV is in a certain range or not is judged by a judging portion. And when the acceleration DELTAV exceeds the range, a corrected duty which increases with a passed time is added to the output duty from a correcting portion.

Inventor: TANAKA OSAMU
IPC: F25B1/00
Filed: 1987-11-26
Abstract: PURPOSE: To widen the operating range of a compressor by regulating the lowest stage capacity of a compressor at a high level under such a situation as the compressor is operated in the vicinity of lowest stage when the refrigerant evaporation temperature is extremely low at the time of multistage capacity control of the pressor. CONSTITUTION: The protector comprises means 50 for regulating the refrigerating capacity by controlling the capacity of a compressor 1, means 51 for detecting the condensation temperature of refrigerant in a refrigerant circulation system Z, means TH7 for detecting the evaporation temperature of refrigerant or a signal corresponding thereto, and means 52 for regulating the lowest stage in the capacity control of the compressor 1 through the means 50 depending on the condensation and evaporation temperatures of refrigerant. Since the lowest stage capacity of the compressor 1 can be regulated to a high level when the outer air temperature is extremely low and the condensation temperature of refrigerant 15 high, circulation of refrigerant is increased in the system Z and temperature rise of the coil and lubricant in the compressor 1 is suppressed.  Consequently, the plant can be operated continuously without triggering a protector.

Abstract: PURPOSE:To surely prevent loosening of a valve holder by applying micro- capsules including binding agent to a thread part, containing a delivery valve, etc., in an element holder, and then threading a valve holder, and installing the element holder by a bolt. CONSTITUTION:A cylinder 16 of a pump element 12 is stopped to a step part 18 in an inner wall of a sleeve part 5 of an element holder 4. A cylindrical valve seat, a valve element and a valve spring 14 for a delivery valve 13 are inserted. Micro-capsules enclosing binding agent are applied to facing surfaces of the sleeve 5 of the element holder 4 and a valve holder 15. The valve holder 15 is tightened to the element holder 4 at a position where a resiliency of the valve spring 14 becomes a predetermined value while measuring the resiliency of the valve spring 14 is measured by a torque wrench or the like. The micro- capsules are broken by a tightening torque, so the binding agent inside is released and fixed to fix the valve holder 15 to the element holder 4. Loosening at a thread part can thus be prevented.

Abstract: PROBLEM TO BE SOLVED: To perform stable reversing operation by providing a control means to move a jogger fence to register a paper sheet in a staple tray up to a guide position of the paper sheet when the paper sheet is switched back and is reversely discharged. SOLUTION: When paper is reversely fed, the size of a paper sheet is confirmed when the paper sheet is carried to a postprocessing device, and a stepping motor 24 is driven by a pulse quantity necessary to move a jogger fence 11 up to a standby position fit for the respective size. When the paper sheet is switched back, the stepping motor 24 is driven in the inverse direction this time to return the jogger fence 11 up to a former home position, and when a home position sensor S5 detects the jogger fence 11, the stepping motor is stopped. Since the above-mentioned operation is repeated every time when the paper sheet is carried, a skew of the paper sheet at reversing time can be prevented.

Title: System and method for step track follow-up, and recording medium for program thereof
Inventor: KATO KATSUHIKO
IPC: G05D3/10
Filed: 1998-10-21
Abstract: PROBLEM TO BE SOLVED: To realize a step track follow-up system wherein the one step angle variation is avoided to operate normally. SOLUTION: When the rotational driving direction of a motor to be driven does not match the rotational driving direction just before driving it, the driving time per step of motor rotation is increased (S11, S12, S13). This driving time is the time of the step size Scv plus a backlash correction value. This compensates the one-step driving angle when the driving direction changes to generate the backlash, and hence the one-step angle variation can be avoided to realize a normal operation.

Filed: 1988-11-28
Abstract: PURPOSE:To thin the thickness of a mechanism part and to make the subject device compact by adjusting the height of a guide part in the widthwise direction of a tape at the time of mounting the tape completely on a head drum with a tape guide positioned in an end of a guide means. CONSTITUTION:A pin 27 and a guide 28 on a slider 25 have no upper flange, but the lower flange is formed by the slider 25 itself. And, members 27 and 28 cannot be changed in height against the slider 25 but are fixed. Then, a screw hole is formed in a bent part of a guide rail 23, and by turning a screw 39 screw-fitted in this hole, a tip part of the rail 23 is moved up and down. Consequently, the slider can also be moved up and down, and a tape path is adjusted in height in a position on the side of a tip of a guide groove 31. Therefore, drawing members 27 and 29 can hardly interfere with a front lid 19 of a tape cassette 10. By this method, the thickness of the mechanical part of the tape mounting device is thinned so that the device can be compact.
