Title: Plasma processing device and control thereof
Inventor: TAKAHASHI NUSHITO
IPC: H01L21/302
Filed: 1994-09-19
Abstract: PURPOSE: To prevent variation in plasma processing characteristics and to enhance availability by heating and controlling the wall and the window of a plasma processing device by infrared radiation. CONSTITUTION: For example, in a μ-wave etching device, the temperature of a semispherical bell-jar 1 consisting of quartz is previously heated to about 200 deg.C, using a far infrared radiation heater 7. Starting plasma processing at this point of time permits etching under the condition similar to a steady state from the beginning. Temperature control is made by turning off the heater 7 or by decreasing its output when excessive temperature rise is observed. Thus a variation in the temperature of the bell-jar 1 is depressed to enhance the availability and the yield of the device. In addition, plasma screening for removing a stuck fragments is applied by setting the temperature of the bell-jar 1 higher than for etching.

Title: Dc motor
Inventor: SAITO FUMITOSHI
IPC: H02K23/04
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To use a DC motor in a narrow space, to suppress the increase of noise when the load of the motor increases even when the thickness of the motor is reduced, and to suppress the increases of vibrations and noise even when the thickness of the motor is further reduced. SOLUTION: A short-circuiting coil 6 is provided so that the coil 6 can be interlinked with a magnetic flux which is generated when a load is applied to a DC motor and an electric current flows to the armature winding 11 of the motor. Since the armature current (secondary current) is generated by the load, the generated magnetic flux changes with time and a voltage is induced in the coil 6. Because of the induced voltage, an electric current flows through the armature winding 11 in the direction opposing to the magnetic flux. Since the thickness of the motor is reduced, the opposite magnetic flux suppresses the variation of the magnetic flux passing through the narrow part 13 of a magnetic circuit between the N and S poles of the motor.  Therefore, the noise and vibration of the motor can be suppressed even when the thickness of the motor is reduced, because the electromagnetic force generated by the variation of the magnetic flux can be suppressed.
