Title: Oscillation detection and automatic control of speed loop gain in servo system
Inventor: IWASHITA HEISUKE
IPC: H02P29/00
Filed: 1989-07-15
Abstract: PURPOSE:To detect the oscillation of a system by setting a position command to zero, giving a velocity command provided with an offset value corresponding to a variation value in a position, and obtaining a point suddenly increasing the maximum amplitude when an actual speed variation at the time of oscillating the servo system is analyzed. CONSTITUTION:A proportional clause 1 amplifies a difference between a position command Pc and an actual position Pr of a servomotor by a gain Kp, and a speed command Vc(in) is outputted. In case of a normal position loop, the Vc(in) is inputted to a speed loop as the speed command, and in case of speed loop gain adjustment, the Vc(in) outputted to the speed loop as a speed command Vc(out) by a function generator 2. In the speed loop, a difference between an actual speed Vt of the servomotor and the speed command Vc(out) is integrated 3 or amplified 4 to generate a torque command. Until the resonance of a mechanical system generates, gains K1 and K2 boost successively, and when the mechanical resonance generates, the amplitude becomes suddenly large. According to the constitution, the oscillation of the servo system is easily detected and, at the same time, the speed loop gain is automatically decided easily.

Abstract: PURPOSE:To remove attached substances on electrode surface and oxidation film and determine exactly the concentration of ions in the water to be tested by moving with sliding a member that is slidable all over the surface on which electrode reaction is conducted. CONSTITUTION:A rotor 13 is mounted on the end face 11 of a cylinderical column, and the rotor 13 is covered with a wear resistant material.

Title: Insulation resistance measurement
Inventor: MATSUNO TATSUJI
IPC: G01R27/02
Filed: 1985-08-20
Abstract: PURPOSE:To always enable accurate measurement of insulation resistance regardless of increase in the floating capacitance, by shifting the frequency so that one of leakage components of two low frequency signals to be applied to an electric circuit is equal in the frequency to the other thereof. CONSTITUTION:Ground leakage currents of two low frequency signals which differ from the commercial power source frequency applied to an electric circuit through the earth wire of a transformer T are separated and extracted with a zero-phase current transformer ZCT connected to the earth wire and a band pass filter BPF2-3 connected thereto to shift the signal frequency of one of the two leakage components to that of the other thereof. In other words, the frequencies of two low frequency signals shall be expressed by f1 and f2 (f1<f2) and the signal of f2 of the two low frequency signals to be fed back to the ground wire is mixed with a signal of the sum (f1+f2) of two low frequency signals applied to the electric circuit. Then, component f1 lone is extracted from the mixed outputs and is subtracted from the leakage component of the f1 signal to cancel the invalid component. Thus, the valid component alone adversely proportional to the insulation resistance value of the electric circuit is derived thereby enabling the detection of the insulation resistance irrelevant to the invalid component.
