Title: Apparatus for measuring frequency characteristics of stepping motor
Inventor: KURAMOTO KAORU
IPC: G01R31/34
Filed: 1991-04-09
Abstract: PURPOSE:To instantaneously measure the characteristics of the max. self-exciting frequency and the max. response frequency with high accuracy by providing a drive part changing the repeated frequency of the drive pulse of a stepping motor to be measured and a control part detecting and outputting the average value or effective value of the drive current of the stepping motor corresponding to the frequency. CONSTITUTION:A stepping motor 1 to be measured, a control part 2, a drive part 3 and a DC power supply 4 are provided. When the repeated frequency of the drive pulse applied to the motor 1 is gradually raised, the DC current A flowing to a resistor 4a is reduced by the effect of the inductance of the winding of the motor 1. When the DC current A reaches a certain point f2, the motor 1 becomes out-of-phase conditions wherein the motor can not rotate in response to the repeated frequency and the inductance of the winding of the motor suddenly lowers and the current A suddenly increases. When the repeated frequency of the pulse is gradually lowered, the motor again starts normal rotation at a certain point f1 and current characteristics show hysteresis characteristics. The point f1 is the max. self-starting frequency and the point f2 is the max. response frequency.

Title: Input system for analog signal
Inventor: NAKAZAWA TSUTOMU
IPC: H03M1/12
Filed: 1985-05-14
Abstract: PURPOSE:To simplify the peripheral circuits of a microprocessor by inputting plural reference comparison signals successively for comparison with respective analog signals while inputting the analog signals to one comparator successively, and specifying the level of each analog signal on the basis of its comparison result. CONSTITUTION:When resistance values of resistances R0-Rn are so set that R0<R1<...<Rn and ports A0-An falls to the earth level in order, the plus input of the comparator 13 rises successively. When the input is lower than the minus input of the comparator 13 which is determined by the resistance value of a sensor S0, the output of the comparator 13 is at a low level, but when the input becomes higher, the output is inverted to a high level. The microprocessor 10 monitors an input port I and obtains resistance value data of the sensor S0 through the ports A0-An held at the earth level at the time of the level inversion, thereby specifying its resistance value. Then, the microprocessor 10 holds a port B1 at the ground level and places other ports B0, Bn, etc., in a high resistance state. Similarly, the ports A0-An are held at the earth level successively and the resistance value of the sensor S1 is specified simultaneously by the data inversion of the input port I. This processing is carried out as to all of sensors S0-Sn.
