Title: Motor controller
Inventor: KITAMURA ATSUSHI
IPC: H02P25/026
Filed: 1991-11-12
Abstract: PURPOSE:To obtain a good characteristic of a motor controller, which is resistant to the change of the voltage of a power supply too, and enable the optimum control gain of the controller to be set, without adding any circuit to the controller, by controlling increase of power supply voltage utilizing ON-OFF control signal of a regenerative control circuit to correct the control gain. CONSTITUTION:In a motor controller, for controlling increase of a DC voltage, caused by the regenerative energy fed from a motor 5, a regenerative control circuit 70 is additionally provided. The regenerative control circuit 70 is so operated that the increase of DC voltage is sensed by a DC voltage sensor 24, and the current application to a regenerative resistor 25 is performed by ON-OFF controlling a transistor 27 for regenerative control, and thereby, the regenerative energy is emitted in the form of thermal energy. A photo-coupler 26 performs the sensing/insulating transfer of the ON-OFF state of a regenerative operation, and is used for sensing the failure of the transistor 27 for regenerative control, under short-circuit state. The binary signal sensed by the photo- coupler 26 is converted into an analog signal by a filter 28, and the analog signal corrects a desired current value 11 by regulating a current control gain.

Title: Electron-density measuring apparatus
Inventor: NINOMIYA HIDEKI
IPC: G01N21/21
Filed: 1989-11-14
Abstract: PURPOSE:To obtain a simple, compact measuring apparatus which has general- purpose applications and can measure electron density readily by providing a constitution wherein laser light is split into two beams, one beam is modulated with a constant frequency, and the other beam is modulated by the change in the refractive index caused by plasma electron density. CONSTITUTION:The laser light emitted from one laser light source is split into two beams through a half mirror 2. One split laser beam is modulated by a constant frequency by using an optical modulator 4. The other split laser light is reflected from a total reflecting mirror 3 and guided to a plasma device 7 through a half mirror 6. The light is modulated based on the change in refractive index caused by plasma electron density. The light which has passed the plasma device 7 is reflected from a total reflecting mirror 8 and reflected from the half mirror 6 again through the plasma device 7. This light and the light which is reflected from a total reflecting mirror 5 through the optical modifier 4 form interference light which is guided to a photodetector 10. The interference beat signal outputted from the photodetector 10 is guided to a demodulator 12 through an HPF 11 and demodulated. Thus the electron density in the plasma is obtained.
