Title: Electric vehicle controller
Inventor: KIMURA AKIRA
IPC: B60L9/12
Filed: 1979-02-02
Abstract: PURPOSE: To smooth control in deceleration, by detecting that the output of a magnetic phase shifter which receives a current command and the output of a direct current transformer becomes zero and by resetting again a flip-flop which receives the outputs of a maximum and a minimum current feeding ratio detecting circuits.  
     CONSTITUTION: To start an electric vehicle, a current command P is applied to a magnetic phase shifter MPS. When the electric vehicle is accelerated, the counter electromotive force of an electric motor MO increases and the output of the magnetic phase shifter rises. When the rise in the output of the phase shifter is detected by a maximum current feeding ratio detecting circuit MAX, a flip-flop is set and a gate signal is applied from a pulse transformer PT to a rectifier Re 1  to turn it on to generate a voltage on the DC side of the rectifier. When the elctric vehicle is decelerated due to an upward gradient, the output of the magnetic phase shifter decreases. This decrease is detected by a minimum current feeding ratio detecting circuit MIN to reset the flip-flop again. As a result, the rectifier Re 1  is turned off and the voltage on its DC side becomes zero. The current control of the electric motor is thus effected by the magnetic phase shifter.

Abstract: PURPOSE:To improve reliability by providing a failure-time rotation detecting means for obtaining the rotating speeds of input side and output side pulleys at the time of the failure of the rotating speed detecting sensors of these pulleys based on other detected values corresponding to the rotating speeds thereof. CONSTITUTION:At the time of the failure of a sensor 94 for detecting the rotating speed of an input side primary pulley, the control unit 91 of a continuously variable transmission obtains the rotating speed of the input side primary pulley by a failure-time rotating speed detecting means, e.g., based on the output signal of an engine speed sensor 96. At the time of the failure of a sensor 95 for detecting the rotating speed of an output side secondary pulley, the rotating speed of the output side pulley is equally obtained by a failure-time rotating speed detecting means, e.g., based on the output signal of a vehicle speed sensor 98. Thereby, the control of belt tension or speed-change control can be properly carried out even at the time of the failure of these sensors, improving the reliability of the continuously variable transmission.

Title: Reduction gear
Inventor: HASEGAWA KANEMITSU
IPC: H02K7/116
Filed: 1986-01-22
Abstract: PURPOSE:To shorten a reduction gear in its longitudinal dimension along the shaft, by setting a cam part, inside of the center part of a rotor supported by a body through a bearing, and engaging the tooth surface of a flexible cylinder fixed to said body and having a gear on its central inner surface, with the gear of a rotary shaft. CONSTITUTION:When rotative force is transmitted from the outside to a rotor 3, a contact point 11 between a cam part 2 and a cylinder 5 makes turning movement. Therefore, a point of engagement between the flexible gear 4 of the cylinder 5 and the gear 6 of a rotary shaft 7, makes turning movement, according to said movement. For example, when the rotor 3 makes one complete turn in the direction indicated by an arrow 17 in the figure, the rotary shaft 7 rotates in the direction indicated by an arrow 18, by the angle corresponding to the difference between the number of teeth of the gear 4 and that of the gear 6. That is, the rotation of the rotor 3 is transmitted to the rotary shaft 7, as reducing its speed in the ratio of the number of teeth of the gear 4, to the difference between the number of teeth of the gear 4 and that of the gear 6. In other words, the input rotation transmitted to the rotor 3, is reduced on the principle of differential gears, and the rotary shaft 7 placed in the direction of the concentric circle, is made to be an output shaft. Accordingly, this reduction gear is shortened in its dimension along the input/output shaft.

Title: Compensation circuit for crystal fault
Inventor: NAGUMO FUMIO
IPC: H04N5/335
Filed: 1979-02-02
Abstract: PURPOSE: To remove the picture distortion and to avoid the deterioration of picture quality, by interpolating the crystal fault noise with the average signal of the bit outputs before and after.  
     CONSTITUTION: The circuit consists of the pick up element 1, delay circuits 5, 6, average value circuit 10, and control circuit 3. The bit signal SO being the output of the element 1 is delayed by one bit with the circuit 5 to output the signal S 1 . Further, the signal S 2  is outputted from the signal SO through the circuit 6 by 2-bit delayed. This signal S 2  and the original signal SO are synthesized in the synthesizer 7 and this synthesized output is fed to the variable resistor 8 for weighting for average. The switching circuit is subject to the control with the control pulse P c  of the control cicuit 3. If no crystal fault is present, the signal S 1  is used as final synthesized bit. When the pulse P c  enters, since the switch is selected to the average signal S 3  side by the section, the signal S 3  is outputted. Thus, the compensation of crystal failure position can be made.
