Title: Manufacture of dielectric isolation substrate
Inventor: TSUKAGOSHI TSUNEO
IPC: H01L21/76
Filed: 1986-09-03
Abstract: PURPOSE:To obtain a dielectric isolation substrate using a bonding material for preventing it from being deformed due to warpage by sufficiently smoothly polishing the surfaces of two semiconductor substrates, and directly contacting the polished surfaces in sufficiently clean atmosphere. CONSTITUTION:After a separating V-shaped groove is formed approx. 50 microns deep with an alkaline etchant which mainly contains KOH on an N-type single crystal silicon substrate 1 of surface index (100), a thermal oxide film 2 is formed approx. 1 micron in an oxidative atmosphere, and a polycrystalline polysilicon 3 is deposited approx. 80 microns thereon. Then, a polycrystalline silicon side is so chemically or mechanically polished as to be sufficiently smoothly to form a polished surface 4 of polycrystalline polysilicon to complete the polishing before exposing the film 2. Further, the mirrorpolished sides of the surfaces opposed to another single crystal silicon substrate 5 of the substrate are directed to be contacted, and heat-treated at 200 deg.C or higher to be bonded. Accordingly, semiconductor devices having different thicknesses of islands of the single crystal silicon can be easily manufactured to ignore the warpage of the substrate.

Title: Diaphragm for speaker
Inventor: IIMURA KATSUHIKO
IPC: H04R7/02
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To enhance the reproduction capability of medium and high pitch sound components in spite of a speaker thin and long in a broadwise direction to cope with a saved space for a speaker system for an AV device. SOLUTION: In the diaphragm for an elliptic or oval speaker, a cross sectional shape in the major axis direction satisfies the following conditions. At a position being a half of a length from an end of an open hole 2 of the diaphragm 1 till an end of the major axis, a height (h) of a passing point of the cross sectional shape in the major axis direction is selected to be within the following range. H/2+H×(a0.05-1)<=h<=H×5/6, where (a) is the aspect ratio of the major axis L1 to the minor axis L2 and H is the total height of the diaphragm. Through the configuration above, the strength around the center of the diaphragm is much enhanced to extend a reproduction band of a high pitch sound component.

Filed: 1982-11-26
Abstract: PURPOSE:To prevent scattering of captured particulates and to reduce the pressure loss, by disposing a filter made of a roughly woven fabric of ceramic fiber on the upstream-side surface of a fine filter in an exhaust-gas purifying apparatus. CONSTITUTION:An exhaust-gas purifying apparatus 3 is disposed in an exhaust manifold 2 of a Diesel engine 1.

Title: Suspension device for vehicle
Inventor: TAGAWA SHINJI
IPC: B60G17/015
Filed: 1992-08-03
Abstract: PURPOSE:To prevent the rise of oil temperature in an active suspension device. CONSTITUTION:A suspension device is provided with an ACS controller 17S and an EAT controller 17T for controlling automatic transmission 105. The ACS controller 17S monitors oil temperature by a temperature sensor 92, and when the oil temperature reaches the specified value or more, the ACS controller 17S operates an electric fan 90 to lower the oil temperature. When the oil temperature is not lowered even with the rotation of the fan 90, the ACS controller 17S communicates with the EAT controller 17T so as to change a speed change line onto the low vehicle speed side. When the speed change line is changed onto the low vehicle speed side, engine speed is lowered, and the oil temperature is lowered. In the case of the oil temperature still being unlowered, regulation is applied to active suspension control.

IPC: H04N7/00
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To easily distinguish respective recorded materials even when the plural materials are recorded in a video/audio material recorder. SOLUTION: In a data base(DB) 6, the auxiliary information of the materials scheduled to be recorded is registered beforehand. The materials are supplied from plural input lines a1 -a2 to a device 1, the device 1 selects one line from the lines a1 -an by the instruction of the device 3 and connects it to the input channel ch1 of the device 2, the input line is connected to the device 2 and the material is recorded. The selection information of the actual input line in the device 1 and the actual recording start time of the material in the device 2 are automatically registered in the DB 6 as the auxiliary information of the material. The plural materials are never recorded in one input line at the same time and the materials whose input line title and recording start time are the same do not exist.  Thus, even when the information of the recording schedule of the material is omitted in the auxiliary information of the certain material, the material is easily uniquely obtained.

Filed: 1988-08-22
Abstract: PURPOSE:To uniformly modulate incident beams by means of a compact optical modulator by arranging shielding plates having slits between a relay lens for converging luminous flux into parallel luminous flux and convergent luminous flux and vibrating the shielding plate. CONSTITUTION:A relay lens 4 for converging luminous flux into parallel luminous flux and a relay lens 5 for converting the parallel luminous flux into convergent luminous flux are arranged between an objective lens 6 and a pyroelectric element 3.
