Title: Speed controller for motor
Inventor: TACHIKAWA MAKOTO
IPC: H02P29/00
Filed: 1983-04-04
Abstract: PURPOSE:To improve the speed controlling accuracy of low speed by increasing the sampling period inversely proportional to the detected value when the speed detected value is less than the specified value, and exponentially reducing the proportional constant of the proportional integration in correlation to the increase in the sampling period. CONSTITUTION:A DC motor 1 is driven by a thyristor converter 2 and controlled in response to a speed control signal 104. The speed of the motor 1 is detected by a speed detector 4, and inputted to a microprocessor 7 through a sampler 5, and compared with speed instruction value NR101. It is also supplied through a sampler 21 to a sampling period setter 22, which outputs a signal inversely proportional to the speed detected value from a sampling period to a sampling period signal generator 11 when the detected speed is less than the specified value, and simultaneously outputs the altered sampling period signal to a speed controller 20. The controller 20 exponentially reduces the proportional constant of the proportional integration in correlation to the increase in the sampling period.

Abstract: PURPOSE:To prevent wasteful battery consumption in a controller which controls the outputs of an electric driving system according to changes in a human leg force by detecting increase or decrease in the measured value of leg force, and comparing the period of that change with a predetermined value to identify any failure. CONSTITUTION:This bicycle has a controller 54 which controls motor current according to a leg force F detected by a potentiometer and generates motor torque so as to control driving of a motor 22.

Title: Detecting device for electromagnetic induction line
Inventor: YAMAKI MASARU
IPC: G05D1/02
Filed: 1986-03-20
Abstract: PURPOSE:To detect the position of an electromagnetic induction line with good accuracy without deviation in the detected position due to various conditions by making the outputted induced voltages pass through the same zero cross point even when the AC currents of the electromagnetic induction line sensed by a first and second sensors are changed. CONSTITUTION:At the same time with the passage of a 1st sensor 4 by the electromagnetic induction line 3, the second sensor 5 approaches the electromagnetic induction line 3, outputting an induced voltage, and the deviation from an induced voltage of the first sensor 4 is obtained to calculate a zero cross point 0. The zero cross point 0 comes to be the central position of a distance l1 between the first and second sensors 4 and 5, and the electromagnetic induction line 3 is seen to be located beneath the zero cross point, and therefore, the position of the zero cross point 0 becomes the position of the electromagnetic induction line 3. Even when the size of the AC currents of the electromagnetic induction line 3 sensed by the first and second sensors 4 and 5 are changed, the induced voltage outputted always passes through the zero cross point 0, and therefore, the detecting position is not deviated and the position of the electromagnetic induction line can always be detected correctly.
