Title: Grinding method and device
Inventor: SATO SHUZO
IPC: H01L21/304
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To make a surface to be ground flat with high accuracy by grinding a surface to be processed while applying bias voltage between the surface to be processed and a grinding tool surface, using conductive processing fluid including grinding particles chargeable to positive or negative. SOLUTION: When an electric field is given to grinding fluid including silica particles S, an electrophoresis phenomenon of silica particles S occurs, and silica particles S are electrically-attracted to a conductive film 34 of positive pole. The silica particles S attracted toward the conductive film 34 is attracted to the surface of the conductive film 34 to form a silica particles layer, so that grinding is conducted under this condition. It is thus possible to attain flat grinding by means of a semifixed abrasive grinding method, and make the ground surface of a wafer 9 flat with high accuracy by means of a synergistic effect of mechanical grinding by semifixed abrasive and chemical grinding by grinding fluid.

Filed: 1984-02-04
Abstract: PURPOSE:To enable a strong frame article to be molded without wasting material and obstructing workability by mixing glass fiber or carbon fiber by a method wherein the nozzle of an extruder is moved along the frame cavity grooved on the bottom force to fill the groove with melted string form resin. CONSTITUTION:When the press C is opened at the beginning of molding, in the extruder B, the nozzle 9 approaches down to the frame groove 2 of the bottom force 1 of the matched metal die A to begin injecting plasticized thermoplastic resin 8 and goes round along the upper part of the groove 2 as it injects the resin. The melted resin 8 injected from the nozzle 9 of the extruder B in the form of a string is put continuously in the groove 2 and when the nozzle has gone round along the groove 2 for one round, the resin is cut. The instant the nozzle 9 leaves the press C, the forces are closed to press the resin. In this manner, the cavity 6 is charged with heated and fluidized resin 8.

Filed: 1980-02-20
Abstract: PURPOSE:To ensure an effective reduction of the noise caused by fading and when the received input is lowered, by breaking the DC signal in the demodulating phase synchronous loop of a gain control signal when the received signal becomes less than the value set previously. CONSTITUTION:The lincompex received signal is converted into the base band signal by the SSB receiver 1 with the subcarrier signal separated and then applied to the phase comparator 4 for a comparison with the output of the variable frequency oscillator 5 in terms of the phase. Then the error signal is applied to the oscillator 5 via the loop filter 6 and the analog switch 10. The output of the loop filter 6 is applied to the expander 7 as a gain control signal to obtain a restored voice signal at the terminal 8. On the other hand, the level of the received signal is detected by the level detector 7. Then the analog switch 10 is opened when the level of the received signal becomes lower than the prescribed value. Thus the control voltage of the oscillator 5 is held at the value immediately before the opening of the switch 10 by the capacitor 11.
