Title: Dielectric separation semiconductor substrate and its manufacture
Inventor: NOMOTO SATORU
IPC: H01L21/762
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To reduce the cost of a dielectric separation semiconductor substrate by reducing the peripheral section of the substrate on which no rotating element can be arranged, and to improve the degree of integration of rotating elements on the substrate and, at the same time, to make the substrate usable at a middle of withstand voltage by vertically digging separating grooves which separate semiconductor crystals from each other by dry etching, etc., regardless of the faces of the crystals. SOLUTION: A single-crystal Si wafer 10 carrying an N<+> buried layer 11 on its surface is separated into many single-crystal Si chips 18, by closely adhering a masking material 14 for trench having separating groove forming windows 12 to the upper surface of the wafer 10, and digging separating grooves 16 into the wafer 10 by dry etching. After an oxide film 20 is formed on the internal surfaces of the grooves 16 and surfaces of the chips 18, the grooves 16 are filled up by depositing Si 22 by the low-pressure CVD method. Then, the surface of the poly-Si 22 is polished to a flat surface, and the wafer 10 is stuck to a supporting substrate 26 composed of a single-crystal Si wafer carrying an oxide film 20 on the surface with the polished surface on the downside by turning over the wafer 10. Therefore, each single-crystal semiconductor chip 18 has a bottom face composed of the defective surface resulting from the formation of the separating grooves and top face composed of an active surface on the opposite side of the defective surface.

IPC: F16H57/04
Filed: 1985-01-19
Abstract: PURPOSE:To prevent oil temperature rise caused by oil agitation by providing the partition of a transmission mechanism case with an oil chamber with an opening to accommodate splashed oil, and also lubricating oil feeding paths to communicate the oil chamber to a radial oil path. CONSTITUTION:The lubricating oil feeding device 1 of a transmission mechanism has an oil chamber 1A, a radial oil path 1B, and oil paths 1B, 1C, and comprises oil paths 1D, 1E formed in a rear transmission mechanism case 75, an oil path 1G forming an opening 1F, and an oil path 1H formed in the second output shaft 52.

A bracket is fixed by screwing screws in tapped holes provided at the end sections of the struts 5. Therefore, a product which has a strong strength and in which winding defects hardly occur can be easily assembled.

Title: Temperature test method for electrical machinery and apparatus
Inventor: MURAYAMA SHIGERU
IPC: H02K11/00
Filed: 1986-01-17
Abstract: PURPOSE:To reduce the draft volume, step up the raise in temperature of a coil and the like and shorten the test time by stopping up a part or whole of the opened area of an inlet of exhaust port with a blocking plate in a fixed time. CONSTITUTION:Prior to the operation of a motor 30 an inlet port 11 an exhaust port 14 are all stopped up with blocking plates 16 and 18. Under the circumstances where a generator 40 is directly connected to a motor 30, the motor 30 is rotated by lowing the current from an AC power source to a stator coil 4 of a motor 30. When a switch 33 is closed and a resistor, which is a load 34, is connected to the generator 40, the motor comes to get loaded. However, as an air inside the motor 30 is stirred by the rotation of a fan 9, the temperature of a coil 4 and the like rises more rapidly than the one in conventional tests. The temperature value of the coil 4 is taken into a control unit 37 from a temperature detector 31, where the surrounding temperature value from a temperature detector 41 is decreased and the value of temperature rise is worked out. Thus, the temperature test time can be shortened through rise is worked out. Thus, the temperature test time can be shortened though a long time has so far been required by the temperature test.

CONSTITUTION:Diethoxymagnesium is suspended in an alkylbenzene (e.g., toluene) in the presence of a Ti-Cl linkage-containing alkoxytitanium compound (e.g., dibutoxytitanium dichloride) and is then brought into contact with TiCl4 whose volume ratio to the alkylbenzene is 1 or below. Then phthalic acid dichloride is added to the mixture at 40 deg.C or above, and the mixture is reacted at a temperature ranging from 80-150 deg.C to give a solid material. The solid material is washed with an alkylbenzene, and reacted with TiCl4 whose volume ratio to the alkylbenzene is 1 or below in the presence of the alkylbenzene to produce the title solid catalyst component. When the solid catalyst component is used together with organometallic components of an organoaluminum compound and a specific silicon compound for polymerization of an organoaluminum compound and a specific silicon compound for polymerization of olefins, the solid catalyst component exhibits high activity and can reduce the catalyst residue in the produced polymer extremely.

Abstract: PURPOSE:To make a low voltage operation at a large power stable by setting pinch-off voltages V1, V2 of 1st and 2nd switching elements employing a gallium arsenide FET so that the voltage V1 is higher than the voltage V2.

Title: Transmission power control circuit
Inventor: IWATA HIROKAZU
IPC: H03G3/30
Filed: 1994-01-28
Abstract: PURPOSE:To reduce failures by lowering a transmission output at the time of mismatch of an antenna and preventing the overheat of a power amplifier part and an output coupling circuit. CONSTITUTION:Because a standing wave is generated when the matching of an antenna 5 and the output impedance of an output coupling circuit 2 is not taken, standing wave voltage is different at least three points A, B and C where reactance is different. The standing wave voltage is rectified by the three detection circuits 1a, 1b and 1c of a detection circuit 1, respectively, and detection voltage is made to be outputted. The detection voltage is synthesized by a synthesis circuit 1d and the voltage is outputted as detection voltage to a voltage comparison circuit 3. Because of the phase deviation of the standing wave voltage of each of the points A, B and C, the phase of detection voltage is also deviated and either one of the three detection voltage is higher than prescribed voltage. As a result, the detection voltage is always higher than the prescribed voltage. In the voltage comparison circuit 3, the detection voltage and the prescribed voltage are compared, control voltage is outputted because the detection voltage is higher and the output of a power amplifier part 4 is lowered.

Title: Manufacture of heat insulating pipe
Inventor: YAMAMOTO YUKIO
IPC: B29C48/09
Filed: 1986-01-17
Abstract: PURPOSE:To improve the adhesion between a coated layer and a metal pipe and prevent only the coated layer from separating from the metal pipe by a method wherein foamed polyethylene with high extent of foaming is directly covered onto the outer peripheral surface of the metal pipe with an extruder after the metal pipe is preheated up to a predetermined temperature in advance in the manufacturing method of a heat insulating pipe. CONSTITUTION:A copper pipe 10 is preheated with a preheating mechanism up to a temperature of 50-60 deg.C. The well-known nipple 40 and die 42 are arranged radially outside the copper pipe 10 so as to feed expandable polyethylene resin 44 through a first step screw and a second step screw to an annular passage made between the nipple 40 and the die 42. The expandable polyethylene resin 44, which is extruded at about 140 deg.C onto the outer peripheral surface 10a, contacts the outer peripheral surface 10a and consequently the inner peripheral surface 46 of the expandable polyethylene resin 44 is once cooled so as to form an inner peripheral layer 48. Because the inner peripheral layer 48 solidifies quicker as compared with a bubble layer 50 at the center of the resin 44, no bubble 52 enters in the inner peripheral layer 48.
