  • Anti-skid brake control system with variable pressure increasing rate
    Patent number: 4660896
    Abstract: An anti-skid brake control system comprises a detector for detecting the peak value of wheel acceleration in each cycle of skid control. Braking pressure is increased in step-wise fashion by alternately operating a pressure control valve between an application mode in which working fluid is supplied to a wheel cylinder to increase the braking pressure and a hold mode in which the wheel cylinder is blocked from fluid communication to a hydraulic brake circuit to hold the braking pressure constant. The duration for holding the pressure control valve in the application mode is adjusted depending upon the detected peak value of wheel acceleration, whereby an average increasing rate of braking pressure is variable depending upon the peak value of the wheel acceleration.

  • System and method for controlling ignition timing of an internal combustion engine
    Patent number: 4660535
    Abstract: A system and method for controlling an ignition timing of an internal combustion engine. In the system, an accumulated value of a deviation or a value corelative to the accumulated value is calculated as an error amount whenever the deviation between a crank angle value at a time when pressure in a combustion chamber has reached its maximum and a target value thereof, whether the error amount exceeds a predetermined allowable limit value is determined whether the error amount is calculated, a corrective amount of ignition timing is calculated when the error amount exceeds the predetermined allowable limit value. Consequently, the correction of ignition timing can be carried out in a quick response during the ransient driving state of engine and engine drivability can be improved.

  • Apparatus for throttle valve control
    Patent number: 4660520
    Abstract: An apparatus responsive to a change in the position of an accelerator pedal for controlling movement of a throttle valve situated within an induction passage. The apparatus includes a control circuit which determines new and minimum values for the position of the accelerator pedal and determines a demand value corresponding to a setting of the position of the throttle valve as a function of the difference between the new and minimum values. The control circuit substitutes the new value for the minimum value when the accelerator pedal remains released and placed at the same position for a predetermined time.

  • Method of automatically measuring blood pressure, and apparatus therefor
    Patent number: 4660567
    Abstract: Method and apparatus are disclosed for linearly pressurizing a cuff, affixed to the limb of a patient, with gas from a liquified gas tank, monitoring Korotkoff sounds that appear and disappear during cuff pressurization to ascertain approximate systolic and diastolic blood pressures as cuff pressurization is in process, halting pressurization at a point slightly higher than the approximate systolic blood pressure and then immediately depressurizing the cuff at a regulated rate to actually measure and determine true systolic blood pressure. Following the determination of systolic blood pressure, the cuff is depressurized at a rapid rate down to a point slightly higher than the approximate diastolic blood pressure and is then depressurized again at the regulated rate again to actually measure and determine true diastolic blood pressure.

  • Anti-lock brake control system including a procedure of sampling of input time data of wheel speed sensor signals and method therefor
    Patent number: 4660146
    Abstract: An anti-skid control system takes a procedure for sampling input time data of every given number of sensor signals, which given number is adjusted so as to a difference of period of time measured with respect to mutually adjacent signal-to-signal intervals is great enough to perform the anti-skid control operation based thereupon. The anti-skid control system processes sampling operation as a job to be performed by interrupting main job for deriving control signal for increasing, decreasing or holding the fluid pressure to be applied to the wheel cylinder. The occurrences of interruption are counted up whenever it occurs and counted down upon each cycle of main job is completed. The job for sampling the input time data a performed at each time of inputting of the every given number of sensor signals.
