Title: Control device for inverter
Inventor: HIRATA YOSHINOBU
IPC: H02P27/06
Filed: 1987-03-04
Abstract: PURPOSE:To allow a motor to continue its operation without stopping an inverter in case large systematic oscillation is caused to a power source, by giving small oscillation speed command to an inverter control circuit as the speed command of an induction motor when an AC power source is in oscillation. CONSTITUTION:Oscillation detecting signals of an AC power source oscillation detection circuit 23 are given to a command discrimination circuit 24 and a speed command circuit 25. When the oscillation detecting signal is inputted, the command discrimination circuit closes (b) of a changeover switch 26. On the other hand, with the oscillation detecting signal the speed command circuit 25 adds the speed command value in oscillation SL to a voltage-frequency command circuit 10 with which a motor 3 can stably be operated even if there occurs voltage fluctuation to the input power from the AC power source 2.

IPC: E02D3/12
Filed: 1985-03-12
Abstract: PURPOSE:To prevent flow-out of a hardener caused by an air lift effect, by a method wherein a fresh water diffusion injection hole for forming high pressure water curtain is formed between a hole for injecting the air through an injection rod and fresh water and an underlaying hardener injection hole. CONSTITUTION:After an injection rod 1 is inserted into a soft ground down to a given depth, fresh water, the air, and a hardener are injected through a first injection hole 6, a second injection hole 8, and a third injection hole by means of flow passages 2, 3, and 4 respectively. In which case, excavated soil containing viscous soil is discharged to a ground surface by an air lift effect, and the ground is filled with the hardener through the third injection hole 9. In this case, formation of high pressure water curtain by means of fresh water injected through a diffusion injection hole 7 formed between the first injection hole 6 and the third injection hole 9 prevents flow-out of the hardener caused by air lift.

Title: Dry etching method
Inventor: SEKINE MAKOTO
IPC: H01L21/3065
Filed: 1986-03-05
Abstract: PURPOSE:To vertically etch a groove having a large aspect ratio at a high speed by disposing a magnetic field generator on a second electrode side opposed to a first electrode for placing a sample, and setting gas pressure to a predetermined value. CONSTITUTION:First and second electrodes 11, 12 are oppositely disposed in a vessel 10. High frequency power is applied from a high frequency power supply 15 through a substrate 13 to be etched to the upper surface of the electrode (cathode) 11 and through a matching circuit 14 to the electrode 11. A magnetic field generator 20 on the upper surface of the electrode 12 forms a predetermined magnetic field between the electrodes 11 and 12 out of the vessel 10, and reciprocates in a direction of an arrow P by a moving mechanism 21. Since a distance between a magnet and a wafer is provided in this system, a high density plasma is formed in a wide range from the vicinity of the anode toward the cathode. When the pressure of the etching gas (Cl2) is 5X10<-3>(Torr) or lower, the etching speed decreases, the etching velocity is decelerated. To effectively vertically etch it without undercut, the gas pressure is preferably 8X10<-3>(Torr) or lower, and may be set to a range of 2-8X10<-3>(Torr).
