IPC: F25B1/00
Filed: 1993-11-17
Abstract: PURPOSE:To eliminate a phenomenon of bubble formation of lubricant oil in a compressor caused by a rapid reduction in low pressure and protect the compressor by a method wherein an upper limit in operating frequency of the compressor is set in the case of an energization of long period of sleeping or an energization of a long piping and then the upper limit of the operating frequency of the compressor is eliminated after a circulation of lubricant is stabilized. CONSTITUTION:A discharging temperature of a compressor is detected by a discharging temperature sensing thermistor 1 and then a detected temperature N is inputted to a micro-computer 2. At the microcomputer 2, the discharging temperature N and a set value ND are compared to each other and calculated. In the case that a relation of N>ND occurs, a compressor 4 is driven up to a specified frequency f2 under an operation of a frequency variable device 3. In turn, in the case that a relation of N<ND occurs, a compressor operating frequency fn and an upper limit value f1 of the compressor operating frequency are compared to each other and calculated. the compressor 4 is operated in such a manner that a relation of fn<f1 may be attained, the upper limit value is eliminated after a circulation of the refrigerant is made stable and then the operation is transferred to a normal driving control. With such an arrangement as above, a phenomenon of generating bubbles of lubricant oil of the compressor caused by rapid reduction in low pressure is prevented in the case of energization at a long period of sleeping or in the case of energization in a long length pipe.

IPC: H01H35/14
Filed: 1987-11-16
Abstract: PURPOSE:To simplify the mechanism and circuit configuration and ensure sensing of vibrations by accommodating all mechanisms in a box, and taking but the condition that the box has received vibrations in the form of electric signals from dislocation of a light sensing part of a reflex type photo-sensor with respect to the mating surface with light reflex plate.

Title: Microwave plasma film forming apparatus
Inventor: AZUMA KAZUFUMI
IPC: H01L31/04
Filed: 1989-11-08
Abstract: PURPOSE:To obtain an apparatus having high reproducibility of a thin film to be formed on the surface of a substrate without influence of propagation of a microwave in a vacuum chamber even if the film is formed on the inner wall of the chamber by covering the inner wall of the chamber with an electric insulator film. CONSTITUTION:When a microwave is generated by a magnetron and guided to a plasma generator 1 by a waveguide 2, the generator 1 is formed in a cavity resonator structure, and a standing wave of the microwave is formed. A magnetic coil 9 mounted on the periphery of a plasma generator 11 generates a magnetic field satisfying an electron cyclotron resonance condition, thus inducing an electron cyclotron resonance. In this case, since the inner wall of a plasma generating chamber is coated with an insulator, even if a semiconductor film is formed on the inner wall, a boundary between conductive metal and the semiconductor is not formed. Thus, even if the semiconductor film is formed on the inner wall of the chamber, loss of the microwave on the inner wall can be reduced, and the film can efficiently be formed with high reproducibility on a substrate 6 to be processed.

Abstract: PURPOSE:To enable operation for high speed rotation by using an electrostatic capacity type position detector having pole plates, which can be disposed in the interior of a bearing. CONSTITUTION:A magnetic bearing is installed in a rotary shaft system of a rotor. The displacement of the rotary shaft system is detected without applying an electric current for detection to the rotary shaft system. An electrostatic capacity type position detector 53 having a pair of pole plates 23 is disposed in the interior of the magnetic bearing 21. Therefore, in case of a radial bearing, the electrostatic capacity type position detector 53 can be disposed in the very narrow interior of the radial bearing. Accordingly it is possible to coincide the position of the radial bearing with the position of the position detector to enable operation for high speed rotation.

Inventor: TATSUMI TETSUYA
IPC: H01L21/302
Filed: 1991-10-09
Abstract: PURPOSE:To perform anisotropy etching with polycide film without using chlorofluorocarbon(CFC) gas. CONSTITUTION:With a wafer temperature controlled below a room temperature, a WSix layer 4 which exists on the upper layer side of polycide film 5 is anisotropically etched, with a side wall protecting film 7 of S(sulfur) being formed, by using S2F2. A polycrystalline silicon layer 3 of the lower layer side is etched by using S2F2/H2 mixed gas under the condition where S/F ratio of etching reaction system is raised. Since S deposition is promoted and the absolute quantity of F* is reduced, abnormal shapes such as undercuts, etc., will not occur on the polycrystalline silicon layer 3. If the polycrystalline silicon layer 3 is etched under the condition with lower incident ion energy or wafer temperature than that of WSix layer 4, anisotropy, base material selectivity, resist selectivity, etc., are further improved.
