Patent JP-H06314657-A (JP)
Title: Manufacture of optical semiconductor element
Inventor: KURODA NAOTAKA
IPC: H01S5/20
Filed: 1993-03-17
Abstract: PURPOSE:To deposit a polycrystal when a growing temperature is low, when a growing pressure is high or a mask area is large in an MOVPE if SiO2 or SiNX heretofore used is used as a selectively growing mask and to further extend selective growing conditions without depositing the polycrystal. CONSTITUTION:When a conventional mask is used, a film has an uncoupled hand, it is coupled to an adsorption species of group III, V materials flown over the mask to cause deposition of a polycrystal. When a mask 21 made of MoSe2 by an MBE growth is used, no uncoupled hand exists on a surface of a film, and hence coupling to adsorption species of group III, V materials on the film do not occur to expect to improve selectivity. An MOVPE can selectively grown even under higher growing pressure and selectively grows at 300Torr or more thereby to extend a wavelength change of am MQW structure due to a mask width as compared with prior art. A loss is reduced in an element in which a DFB laser formed at the selective growth and a semiconductor optical modulator are integrated thereby to increase a modulation band.

Title: Radio communication equipment
Inventor: IGUCHI MASAHIRO
IPC: H04L12/801
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To attain efficient communication at all times even under various communication qualities of a radio transmission channel. SOLUTION: In this radio communication system, a re-transmission control section 8a allows a signal processing unit 3 to transmit a re-transmission request packet when a reply with respect to a packet transmitted by the signal processing unit 3 is not received until a reply wait time expires. A radio communication quality measurement section 5 and a communication quality state notice section 6 in such a communication state obtain a radio communication quality value denoting communication quality of a radio transmission channel quantitatively. A reply wait time expiration time setting section 8c variably sets a reply wait expiration time used by the re-transmission control section 8 on the basis of the radio communication quality value obtained by the radio communication quality measurement section 5 and the communication quality state notice section 6.

Abstract: PURPOSE: To obtain a 1,3-dioxole useful as a monomer for preparation of a fluoropolymer by reacting a dioxolane with a dehalogenating agent.  
     CONSTITUTION: A dioxolane of formula I (X 1  and X 3  are each F or H; X 5  and X 6  are each F or CF 3 ; X 2  and X 4  are each Cl or Br) is reacted with a dehalogenating agent (e.g.; metallic zinc) in the presence of sodium iodide or potassium iodide and sodium carbonate or potassium carbonate in a solvent (e.g.; DMF) at 50-100°C, to obtain a dioxole of formula II. The dioxolane of the formula I is obtained by reacting a bis(fluorooxy)perfluoroalkane with a halogenated olefin at -140 to 60°C. If two halogens to be removed, that is, X 2  and X 4 , are present at anti-positions in the compd. of the formula I, the dehalogenating reaction is proceeded in a high yield.

Title: Surface acoustic wave resonator
Inventor: KANDA TADASHI
IPC: H03H9/25
Filed: 1992-02-12
Abstract: PURPOSE:To provide a small-sized small-capacitance surface acoustic wave resonator by arranging an interdigital transducer with a metal whose specific gravity is large on the surface of a rotation Y cut LiTaO3 piezoelectric substrate and exciting Love wave type surface acoustic waves in the direction of an X axis. CONSTITUTION:The interdigital transducer 2 provided with terminal 4 and 4' is provided on the surface of the rotation Y cut LiTaO3 piezoelectric substrate 1 cut by a prescribed angle within a range where a rotation angle from a Y axis is -10 deg. to +50% on a Y-Z plane with the Y axis as a normal line. The electrode of the interdigital transducer 2 is not an electrode having a uniform thin film and is sufficiently thickened by the metal whose specific gravity is large such as gold, platinum and silver, so that an effect equivalent to the uniform film can be obtained and pseudo surface acoustic waves can be transformed to the Love wave type surface acoustic waves. Thus, a Love wave type surface acoustic wave resonator much smaller than the surface acoustic wave resonator utilizing a LiTaO3 piezoelectric substrate for not largely depending on the accuracy of cut rotation angle whose capacitance ratio is small can be obtained.

Title: Extractor of gas dissolved in oil, fault diagnostic apparatus and oil filled electric equipment
Inventor: KAWAMURA KENICHI
IPC: H01F27/12
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To extract promptly and easily gas dissolved in oil without upsizing the apparatus. SOLUTION: An extractor 10 of gas dissolved in oil is submerged in insulating oil 2 in an extracting container 11 and is provided with two polymer membranes 12a and 12b which allow the gas dissolved in the insulating oil 2 to pass through and extract it in a gas storing chamber 13. When compared to a conventional technique in which the insulation oil passes through only one polymer membrane for extraction, the area of the polymer membranes becomes larger though they are not upsized. Additionally, though the gas storing chamber 13 is formed by the two polymer membranes 12a and 12b, it is not so thick that the extracting container 11 becomes thicker. The apparatus accordingly can be as small-sized as ever.

Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To prevent accidental separation of a rear side electrode by performing back-etching which cleans the rear surface of a substrate and after that, plasma-processing a silicon surface. SOLUTION: A silicon substrate 11 is provided, and a base area 14 is formed on the surface of an epitaxial layer 12.

After formation of a contact hole and electrode 20, in order to clean the rear surface of the substrate 11 polluted in the process, wet etching is performed. On the silicon surface which is mirror-finished by wet etching, irregularities are formed again by plasma treatment, so that a back surface electrode 21 is formed.

Title: Catalyst burner
Inventor: MATSUMOTO IKUO
IPC: F23D14/18
Filed: 1984-03-26
Abstract: PURPOSE:To prevent an oxidation catalyst body from being cooled from the outside, to maintain a uniform heat throughout the whole surface of the oxidation catalyst body, and to prevent slip of fuel as much as possible, by a method wherein an outer peripheral frame in contact with the oxidation catalyst body is heated by an electric heater. CONSTITUTION:Fuel gas is uniformly dispersed through a fuel dispersion pipe 10, flows through a diffusion mat 4 and an oxidation catalyst body 1, and is ignited at its surface, and flame is formed throughout the whole surface. After several tens seconds elapsed, the oxidation catalyst body 1 itself is heated by the flame, and is naturally shifted to catalyst combustion. During shifting to catalyst combustion, a surface heater 9 is energized, an outer peripheral frame 3 itself is heated, and the outer peripheral part 2, in contact with the outer peripheral frame, of the oxidation catalyst body 1 is also heated. When no surface heater 9 exists, the heat in the outer peripheral part 2 of the oxidation catalyst body 1 is more apt to escape to the outside as compared with the central part 2, and slip of fuel gas is susceptible to occur. However, location of the surface heater 9 causes almost uniformization of the temperature of the oxidation catalyst body 1, and fairly decreases slip of the fuel gas.

Abstract: PURPOSE:To make uniform the recorded density, by a construction wherein an individual conductor having a bonding terminal end face effectively shortened to the side of a central part of an IC is provided with a conductor resistance correcting region longer than that of an adjacent individual conductor having an effectively longer bonding terminal. CONSTITUTION:In the conductor resistance correcting regions (n) of the individual conductors L1-Lm connected respectively to heating resistors R1-Rm, the length of the ragions (n) is not sequentially monotonously decreased in the direction from the bonding terminal T1 or Tm toward the bonding terminal Tp or Tg, but is locally increased in some areas, and the lengths of the bonding terminals T1-Tm connected to the individual conductors L1-Lm corresponding to the areas are gradually or monotonously reduced to the side of the center of the IC. Accordingly, resistances of the conductors L1-Lm can be made uniform, whereby the density of images recorded by the thermal head can be made uniform, and the size of the head can be reduced.
