Abstract: A transmission ratio control apparatus for a friction-wheel CVT requires no feedback of the offset of a friction wheel and performs stable transmission ratio control. A control circuit is provided for controlling the offsetting of the friction wheel to change transmission ratio. A first unit of the control circuit determines a target input rotational speed based on the throttle valve opening and the vehicle speed. A second unit determines target transmission ratio corresponding to the target input rotational speed. A third unit determines an rotational angle instructional value for a motor to achieve the target input rotational speed. A fourth unit determines a changing rate of actual transmission ratio based on the input rotational speed and the vehicle speed. A fifth unit corrects the motor rotational angle instructional value to reduce changes in transmission ratio as the transmission ratio changing rate increases, and outputs the corrected instructional value to the motor.

Abstract: To produce a time-base signal for timekeeping, an oscillator circuit generates an oscillator clock signal, which is counted cyclically with a programmable cycle length to establish a time-base cycle. The time-base signal is set and reset once in each time-base cycle. The oscillator clock signal is also counted with a fixed cycle length to establish an adjustment cycle, which is longer than the time-base cycle. In each adjustment cycle, the length of one or more time-base cycles is altered by a total amount determined by adjustment data stored in a non-volatile memory, then the time-base cycle length is restored to its nominal value. The average frequency of the time-base signal can be adjusted by writing appropriate adjustment data in the non-volatile memory.

Abstract: Sensors (20, 21) provide a degree of throttle valve opening (TVO) and an output shaft revolution speed (No) to CPU (10), respectively. CPU (10) carries out a fuzzy inference for each gear position based on two kinds of parameters referring to a driving force deviation (Ef(i)) and a fuel consumption ratio (Qf(i)), and selects a speed change ratio which makes the appraisals for the driving force deviation and the fuel consumption ratio best, as a mark speed change ratio for the next gear position (NextGp), according to a predetermined program. Thus the shift control system selects a gear position corresponding to the speed change ratio by which the deviation between the driver's requiring driving force and the driving force after shifting becomes few, while the fuel consumption ratio becomes good.

Abstract: In a closed type thermal power generation plant, the fuel is supplied in the combustor and burnt therein in the presence of oxygen, instead of air. The combustion gas mainly including water and carbon dioxide is delivered from the combustor into the turbine. A turbine exhaust gas is fed into the waste heat boiler to carry out heat exchanging operation therein and an exhaust gas mainly including water component and carbon dioxide from the waste heat boiler is fed into the condenser. The gas component mainly including the carbon dioxide is separated from the condensate in the water-gas separator and may be fed into the combustor in a compressed state, or the separated gas component may be recovered externally to the plant without emitting the same into the atmosphere. The separated condensate is fed into the waste heat boiler to be subjected to heat exchanging operation therein to generate superheated steam which is to be fed into the combustor, or may be recovered externally.

The system also includes a road surface condition detector which detects a condition of a road surface on which the vehicle is running on the basis of a change of the damping force of the shock absorber. Further, the system includes a damping force adjustment correcting unit which corrects the adjustment reference value by learning the adjustment reference value on the basis of a parameter related to the damping force of the shock absorber which reflects the condition of the road surface.

Abstract: A ratio control for a continuously variable transmission is disclosed. In this control, a speed sensor detects a wheel speed of a driving road wheel drivingly coupled with the continuously variable transmission, and the sensor output, namely a speed indicative signal indicative of the wheel speed detected, is used in conjunction with an engine load indicative signal in deriving a target value in a predetermined reduction ratio dependent variable, such as a turbine speed. Then, an actuator effects a shift in reduction ratio in such a direction as to bring an actual value in the predetermined reduction ratio dependent variable into agreement with the target value. During braking condition, the speed indicative signal may drop to zero or a small value owing to a wheel slip, resulting in a change in target value which causes a shift toward the maximum reduction ratio.

Abstract: The present invention relates to a method of and a system for controlling a reduction ratio in a continuously variable transmission. An actuator for controlling the reduction ratio is controlled in response to an output signal. Normally, there is set as the output signal a sum of a feedback value of a deviation between a target value and an actual value of a turbine revolution, i.e., a revolution speed of an input shaft of the continuously variable transmission, and a feedforward value of the deviation. However, in the present arrangement, the feedback value is neglected and the feedforward value only is set as the output signal when there is a demand for a downshift with power.

By the action of a switch in accordance with the detected state, when the device is in the playback state, the manually input data is directed to the operation controller and is used for controlling the video signal recording and playback unit and the travel speed controller. When the device is in the stop state, manually input data is directed to the memory timer and stored in the memory timer as the preset data.
