Inventor: YOSHIMURA HIRONORI
IPC: C23C16/26
Filed: 1988-03-07
Abstract: PURPOSE:To aim at prolonging the life of a cutting tip by setting the content of Co in a tungsten carbide group ultrahard alloy base to a value between 0.5-3.5%, by forming a diamond coated layer on the surface of the base, and by setting the rake angle of the breaker to an angle between 20-35 deg.. CONSTITUTION:The content of Co in a tungsten carbide group ultrahard base in a cutting tool is set to a value between 0.5 and 3.5, and the rake angle of a breaker formed on the rake surface of a cutting blade of the tool is set to an angle between 20 deg. and 35 deg.. A diamond coated layer is formed on the outer surface of the cutting tool by a chemical evaporation process. With this arrangement, it is possible to remarkably restrain Al or Al alloy chip from being fused to the rake surface of the cutting blade so as to prevent occurrence of microchipping, thereby it is possible to enhance the life of the cutting tool.

Title: Energy conversion system
Inventor: TOMITA TSUTOMU
IPC: F01K25/00
Filed: 1985-03-19
Abstract: PURPOSE:To provide for oneself a considerable part of the enthalpy increase in a Rankine cycle heating caporization process by the heat transfer between a Rankine cycle and the cooling and heating cycles installed outside the Rankine cycle. CONSTITUTION:In cooling and temperature raising cycle, the fluid which flows in a circulation passage is pressurized by a compression pump P-2 and jetted out of the nozzle of a jet pump JP-1. Therefore, the low-pressure gas which recovers heat from the fluid on a Rankine cycle side by a low-pressure heat exchanger E-1 and is heated by a superheater E-5 is inhaled through a conduit connected to the low pressure side, and mixed with the high-pressure liquid jetted out of the nozzle and forms high-pressrue liquid. Since heat is transferred to the Rankine cycle side fluid by high-pressure heat exchangers E-3 and E-2, the input calorific heat of the external energy by a heat exchanger E-4 for temperature rise can be reduced.

Title: Rotary compressor
Inventor: OZU MASAO
IPC: F04C29/02
Filed: 1982-03-31
Abstract: PURPOSE:To raise the compression efficiency of a rotary compressor, by forming oil grooves in sealing surfaces of a compressor section, leading lubricating oil from an oil sump to the oil grooves by use of difference of pressure in an enclosed container and that in a cylinder chamber, and preventing leakage of gas from the clearances formed at sealing surfaces by the lubricating oil delivered to the oil grooves. CONSTITUTION:In operation of a compressor, pressure of gas in an enclosed container 1 is raised. Therefore, if even a small clearance is formed between a cylinder 8 and respective sealing surfaces 9a, 10a of a main bearing 9 and a subsidiary bearing 10, pressure in oil grooves 13 formed along the outer peripheral portions of the sealing surfaces 9a, 10a becomes equal to the pressure in the enclosed container 1 and higher than the pressure in a cylinder chamber 11, so that lubricating oil in an oil sump 15 is carried into the oil grooves 13 from through-holes 14. Here, since the oil grooves 13 are formed along the entire circumference of the sealing surfces 9a, 10a, leakage of gas from the cylinder chamber 11 is prevented completely. Thus, it is enabled to raise the compression efficiency and to reduce the power consumption.

Title: Region-selective crystal growth method
Inventor: MOCHIZUKI YUSHI
IPC: H01L21/20
Filed: 1991-02-27
Abstract: PURPOSE:To form a fine structure directly inside a compound semiconductor crystal from a growth stage. CONSTITUTION:When a compound semiconductor crystal is formed by an atomic layer epitaxial(ALE) method, a laser beam is irradiated parallel to a face immediately on a growth face and the electron state of medium molecules 12 inside the passage region 14 of the beam is changed. Thereby, the adsorption of the growth medium molecules 12 to the growth face is controlled, and a fine structure is formed. As different from a case where a posterior treatment such as an etching operation or the like is executed repeatedly to a uniformly grown crystal and a fine structure is formed, the fine structure can be obtained with good efficiency and with good accuracy.

IPC: C10N40/30
Filed: 1983-03-31
Abstract: PURPOSE:To provide a lubricating oil for a rotary compressor of a refrigerator consisting mainly of a specified diol, in which Freon solvent is difficultly soluble and which increases the efficiency of the compressor and reduces power consumption.

Patent JP-S59183113-A (JP)
Title: Pivot pin assembly
Inventor: DEEBITSUDO JIYOSEFU IISUTON
IPC: F16C11/06
Filed: 1984-03-21
Abstract: A pivot pin assembly is disclosed which eliminates the need for a high pre-load torque to be applied in order to fix a friction-reducing element relative to the pivot pin. The pivot pin assembly includes a pivot pin having a shoulder formed on a central cylindrical portion thereof which is received in the bores of a forked member and in the bore of an intermediate member located therebetween. The pivot pin, has a conical surface at one end and is held fast in the bore of the other forked member by a collet which also has a tapered surface. The tapered surfaces of both the pin and the collet are mateable with the surfaces of the bores in the forked members as the collet is physically bolted to the pivot pin. A friction reducing element, having an inner and an outer race, is positioned about the central portion of the pivot pin such that the outer race is press-fitted into the bore of the intermediate member while the inner race is slidably received on the pivot pin and abuts against the aforementioned shoulder. An axial force is applied to the inner race by a compression spring which is positioned about the periphery of the pivot pin between the collet and the friction reducing element. The spring takes up slack between the collet and the pivot pin shoulder such that the conical surfaces can tightly interact. The spring also permits the friction reducing element to be held fixed relative to the pivot pin without requiring a high pre-load torque to be applied to the attaching bolt.

Title: Both polarized wave transmission system
Inventor: KANEKO ICHIRO
IPC: H04J11/00
Filed: 1991-01-31
Abstract: PURPOSE:To provide both polarized wave transmission systems by which a system gain can be easily calculated in a radio system design. CONSTITUTION:A frequency band width B1, radio channels 11, 31, 12 and 32 of center frequencies (f)1 and (f)3, frequency band width B2, and radio channels 21, 41, 22 and 42 of center frequencies (f)2 and (f)4 are respectively arranged on a vertical polarized wave face and a horizontal polarized wave face. Signal having the same capacities are transmitted by using 16 QAM and 64 QAM transmission systems respectively at the radio channels of the band widths B1 and B2, so that the frequency band width B2 can be narrower than the frequency band width B1. Therefore, received input electric field threshold values of the radio channels on both the horizontal and vertical polarized waves having the same center frequencies, are equal, and the system gain can be easily calculated only by searching the threshold values of the radio channels on the one side polarized wave face.
