Title: Rotary compressor
Inventor: TSUCHIYA KOICHI
IPC: F04C29/02
Filed: 1989-12-05
Abstract: PURPOSE:To prevent lubricating oil from flowing into a refrigerant circuit by installing a partition plate with an opening at the opposite rotational side of a motor element, in an inlet part of a refrigerant discharge pipe piercing through a closed case at the side of a compressor element. CONSTITUTION:Lubricating oil 5 is drawn out of an oil feeding spring, flowing into a compressor element 4, and its part is discharged to a closed case 2 from a refrigerant discharge port 6a together with a refrigerant gas after being turned to an oil mist. This misty lubricating oil 5 receives the effect of rotation of a motor element 3 in the closed case 3, whereby it turns in the same direction as the rotational direction. This swirling oil mist is changed of its flow at a refrigerant discharge pipe inlet by a partition plate 11, and since in this partition plate 11, the opposite rotational side of the motor element 3 is opened, only the refrigerant gas separated from the lubricating oil 5 is discharged out of a refrigerant discharge pipe 7. Therefore various problems due to an inflow of the lubricating oil into a condenser are thus solvable.

Filed: 1993-12-16
Abstract: PURPOSE:To quickly dissolve an insulating film on a semiconductor wafer in high purity by supplying the high-purity vapor of a reagent to the surface of a sample through a filtering member by heating a larger amount of chemical as compared with the case where the chemical is naturally vaporized. CONSTITUTION:A vapor phase treating device for semiconductor wafer is basically divided into a gas generator (right side) which generates a high-purity refined gas, reaction vessel 16 which houses a sample and dissolves a dielectric film on the surface of the sample by causing the sample to react with the refined gas, and exhaust gas processing vessel 10. The vessel 2 having an opening 1 houses a liquid-like reagent 3. The opening 1 is covered by putting a hydrophobic porous film 4 on the opening 1. A heating means 5 is positioned near the vessel 2 so as to heat the inside of the vessel 2. The amount of the vapor of the reagent 3 contained in the vessel 2 is increased by heating the reagent reagent 3. The vapor of the reagent 3 thus generated is supplied to a gas supplying system 8 through the film 4. When the vapor of the reagent 3 is passed through the film 4, mists having large diameters contained in the vapor are intercepted by the film 4.

Title: Hollow chisel
Inventor: MUTOU EISUKE
IPC: B27F5/10
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To eliminate the clogging of cutting chips even if the feeding speed of a double threaded drill type hollow chisel is increased. SOLUTION: The central angle for coupling the front and rear sides of a marking blade to the axial center is in a range of 20 to 50 deg. as seen from the end face of the end blade 22 of a hollow chisel drill 20. The maximum thickness tmax of the drill body 21 in the section in the direction perpendicular to the shaft is in a range of 0.1 to 0.3d. The twist of the cutting chip discharge groove of the body is 1.5 to 4.0d in terms of lead L. The circular arc-like marking blade extended along the outer periphery of the end blade is fallen in a small specified range to thereby increase the sectional area of the cutting chip discharge of the end blade. Particularly, the central angle of the opening of the outer periphery of the groove is increased to make it possible to scrape the chips cut by the drill and hollow blade to the groove of the end blade without difficulty. Further, the groove of the body is formed in the shape to make it possible to smoothly discharge large quantity of the chips fed in the groove at a high speed in a short time to make it possible to smoothly convey the chips without clogging in the groove, thereby making it possible to discharge from the window.

Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To cope with a load even when the load applied to a coil spring is heavy by compressing a spring held by claws provided on arms in response to the pressurized oil from a hydraulic unit. SOLUTION: During the period of compression stroke, when highly pressurized oil is introduced into an oil chamber 26B to return the oil in an oil chamber 26A to a tank, a piston rod 23 contracts. In this case, when a spring 13 is loaded between arms 6 in state where the spring is engagingly locked to claws provided on the arms 6, the spring 13 is compressed to be deflected. When the spring 13 is held in an optional position, the piston rod 23 can be contracted up to a specified position to stop a pump to lock the oil pressure. Then, the spring 13 can be assembled to a strut-ass'y, or removed in compressed state.

Patent JP-H024174-A (JP)
Title: Heat pump
Inventor: OSAWA SEIICHI
IPC: F02G1/045
Filed: 1988-12-16
Abstract: PURPOSE:To control the output of low temperature water over a wide range and improve operation efficiency by allowing a motor to operate and a rotary shaft to increase its rotary speed when a rotary speed required from a load side exceeds a rotary speed of self operation, and forcing a brake to operate and the rotary shaft to reduce its rotary speed inversely when a required rotary speed fails to exceed the rotary speed of self operation. CONSTITUTION:When a rated output of cooled water is excessive to, say, a cooling load, the cooled water outlet temperature of an endothermic heat exchanger 12 drops below a predetermined temperature. A comparison means 33 compares a required rotary speed calculated based on the differential temperature with a rotary speed nn of self operation and issues a command that the required rotary speed should be below the rotary speed of self operation, thereby actuating a brake means 35. As a result, a signal transmitted from a controller 32 forces a brake 29 to act so that the rotary speed of a rotary shaft 24 may be reduced to the required rotary speed. On the contrary, when the output of cooled water is insufficient to the cooling load, the comparison means 33 issues a command that the required rotary speed should exceed the rotary speed of self operation, thereby actuating a back up means 34. As a result, a signal transmitted from the controller 32 forces a motor 28 to operate so that the rotary speed of the rotary shaft 24 may be increased up to the required rotary speed.

The area is outline-traced so as to divide it into an external outline and an internal outline. The outline whose original picture density is lower or the outline with higher density is set to be the real edge line of the object.
