Title: Actuator controlling method
Inventor: NISHIGUCHI NOBUYUKI
IPC: G05D3/14
Filed: 1983-12-08
Abstract: PURPOSE:To prevent overshoot of an actuator by controlling the controlled variable of the actuator in such a way that positional information is made to correspond to a target controlled variable converted into a cycloid function. CONSTITUTION:The deviation DELTAtheta between a target stopping position thetaref and currently detected position theta of the actuator 1 of a motor, hydraulic cylinder, etc., is converted into a cycloid function at a function converting means 2 and the target value omegaref of a control variable is calculated. The actuator 1 is driven by a servo-amplifier 3 so that the target controlled variable omegaref and a detected speed omega can coincide with each other. To move the actuator 1 from a prescribed position theta0 to the target stopping position thetaref, the speed change is controlled by using the cycloid function as a parameter to prevent abrupt change of the moving speed when the movement is started and stopped.

Abstract: PURPOSE:To correct difference in air-fuel ratios at every cylinder and make a real air-fuel ratio close to a target air-fuel ratio by determining a cylinder to be learned by means of the difference in feedback compensated values and the air-fuel ratio detected at each cylinder. CONSTITUTION:Oxygen sensors 16 are provided at the exhaust collection part of two cylinder groups of which exhaust strokes are not close to each other in an exhaust manihold 8, and an air-fuel ratio of air-mixture sucked into an engine 1 via oxygen concentration in the exhaust air is detected. In the case deviation in the air-fuel ratios of a specified cylinder is at a specified level or more, a feedback compensated value is set by a control unit 12 based on an average level of the detected air-fuel ratios at every cylinder. A learning compensation quantity of the cylinder of which air-fuel ratio is deviated in the same direction as the deviated direction of equalized value of the feedback compensation value is corrected and rewritten. Consequently, since the difference in the air-fuel ratio at every cylinder is corrected, a fuel injection quantity is feedback-controlled so that the real air-fuel ratio comes close to the target air-fuel ratio.

Filed: 1995-09-11
Abstract: PURPOSE: To perform temp. compensation of a liquid crystal element using a ferroelectric liquid crystal without a problem practically by adjusting both of a drive pulse width and a drive voltage and performing the temp. compensation.

When the time constant of the pixel farthest from the input terminal is calculated, it is 35μsec, and then, the drive voltage is corrected by a circuit performing temp. detection by a thermistor, and the correction is adjusted so that the drive voltage becomes the maximum drive voltage 25V of a driver in the temp. range of 5-26 deg.C, and the drive voltage changes in the range of 25V-5V in the temp. range of 26-40 deg.C.  In such a manner, by adjusting the drive pulse width and the drive voltage so that the change width of the drive voltage changes small in a low temp. area, and it changes large in a high temp. area, the characteristic of the liquid crystal element for temp. is compensated.

Filed: 1991-09-12
Abstract: PURPOSE:To avoid dirt in picture images even when the outer walls of microcapsules remain on a picture image area of an image receiving paper by forming the outer wall of microcapsule from a thermoplastic resin. CONSTITUTION:This microcapsule 1 consists of an outer wall 2 comprising a thermoplastic resin and an inner content 3 comprising a mixture of photosensitive material and dyestuff such as dye, pigment or dye precursor sealed in the wall 2.
