Title: Operation control system of galvanometer for scanner
Inventor: TORII NOBUTOSHI
IPC: G02B26/10
Filed: 1990-06-22
Abstract: PURPOSE:To accurately control an oscillation angle over the whole operation angle and to usefully and effectively execute measurement based upon laser beams by providing the galvanometer (GM) operation control system with a memory for storing the waveform data of a GM driving command current, an address circuit, a D/A converter, a GM driving circuit, and an oscillation mirror. CONSTITUTION:The GM driving command current is obtained by synthesizing a constant speed command current and an accelerating/decelerating command current. The memory 43 stores the waveform data of the GM driving command current, the address circuit allows the memory 43 to output the waveform data at prescribed intervals, the D/A converter 44 receives the output, converts the received data into an analog value, the driving circuit 45 drives the GM 22, and the GM 22 oscillates the oscillation mirror 23 to retrieve a welding line. Thereby, the GM 22 is driven at a constant angular speed at points other than an oscillation angle folding point in accordance with the waveform of the GM driving command current and driven at a constant angular acceleration at the oscillation angle folding point. Consequently, the oscillation angle can be accurately controlled over the whole operation angle and measurement based upon laser beams can be usefully and effectively executed.

Title: Deciding method for insulation deterioration of cable
Inventor: KASAHARA TOSHIO
IPC: G01R31/12
Filed: 1981-10-16
Abstract: PURPOSE:To exactly decide insulation deterioration, by compensating a voltage dropped portion due to a leakage current from a terminal part of a cable, and always maintaining normal residual charge. CONSTITUTION:Between a electric conductor 2 of a cable 1 to be measured and a shielding layer 3, DC voltage 4 of high voltage is applied through a high voltage switch 5 for a specified time, by which the cable 1 is charged. When charging voltage has reached a specified value, the switch 5 is opened, and after that, self-discharge is executed by residual charge of the cable. When the measurement is being executed, if a part of residual charge drops residual voltage in  the cable by a leakage current flowing through the outside surface of a bushing  7 constituting a cable terminal part 6, by its portion, the measurement becomes  incorrect. Therefore, a dropped portion of the residual voltage is compensated by feeding back an output of an amplifier 9 connected between the electric conductor 2 and a guard electrode 8 provided on the terminal part 6 by separating from its tip part by necessary length, to the DC voltage 4. In this way, the insulating deterioration can be decided exactly.

Title: Method for operating membrane module
Inventor: SASAKI MITSURU
IPC: B01D61/22
Filed: 1985-07-25
Abstract: PURPOSE:To continuously operate the titled module at a low level and to concentrate to a high degree by sending a part of the liq. concentrate at the outlet of the membrane module directly to a booster pump without passing through a tank when the liq. level in the tank reaches the specific level at the vicinity of a tank bottom. CONSTITUTION:A level switch 8 is provided at the minimum level Lmin in a tank 1 at which the air sucked by a pump 2 is not mixed. When the raw soln. concentrated by a membrane module 4 is returned into the tank 1 and again concentrated and the process is repeated, the liq. level in the tank 1 lowers and reaches the liq. level Lmin. At this time, a valve V3 is appropriately opened by the operation of the switch 8, a valve V4 is slightly opened and a part of the raw soln. is directly sent to the inlet side of the pump 2 from the outlet side of the module 4. Consequently, the flow rate in a pipeline 3 for discharging the soln. from the tank 1 is reduced as compared with the time when the valve V3 is fully closed, the rapid current due to the suction at the bottom of the tank is moderated and the concentration can be continued beyond the liq. level Lmin.
