Title: Curable resin composition
Inventor: TAKIYAMA EIICHIRO
IPC: C08F290/00
Filed: 1989-10-19
Abstract: PURPOSE:To obtain a resin composition which can give a molding having sufficient hardness, elongation and boiling resistance and an excellent marblelike pattern by using an acid anhydride polymer and a vinyl ester resin having epoxy and (meth)acryloyl groups. CONSTITUTION:A curable resin composition comprising a polymer having at least one acid anhydride group in the molecule (e.g. a polymer comprising a combination of 99mol of styrene with 1mol of maleic anhydride) and a vinyl ester resin having 0.5-1.5 epoxy groups and 0.5-1.5 (meth)acryloyl groups in the molecule (e.g. a resin obtained by reacting methacrylic acid with an epoxy resin having an excess of epoxy groups and shown by the formula). This composition generates heat gently during curing, is resistant to cracking, and can give a cured resin which is hard but is extensible and tough. In has a good boiling resistance, can easily give a molding having a transparent and marblelike appearance and can be used for the production of bathtubs, washbowls, etc.

Title: Magnetron
Inventor: IDE TETSUYA
IPC: H01J23/04
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent a work function change (decrease in emission current), discharge break down of an emitter, and the like, accompanying an increase in gate current, by adopting two electron emission sources, an electron emission source to be used at a lower voltage than a positive electrode voltage and a secondary emission source with a secondary-emission ratio larger than a specific value under the magnetron operating conditions. SOLUTION: Two kinds of electron emission sources are adopted, an electron emission source, such as a triode-structured field emitter array 32 integrated by micro machining techniques, to be used at a lower voltage than a positive electrode voltage, and a secondary emission source 35. The emitter array 32 supplies electrons to a magnetron until it starts operation, and the secondary emission source 35 with a secondary-emission ratio of its negative electrode surface larger than one in an interacting space, supplies electrons while the magnetron operates. Because an insulating layer 34 is formed on a gate electrode 33 of the emitter array 32 and the secondary-emission film 35 is formed thereon, when an output is increased, most of reverse-impact electrons collide with the secondary-emission film 35, and breakage, etc., of the emitter array 32 can be prevented.

Title: Working method by using fluid
Inventor: TAKASHITA JUNJI
IPC: B24C3/32
Filed: 1986-11-12
Abstract: PURPOSE:To make accurate grinding and polishing in fluid work for a lens or the like, by swinging a jet nozzle of working fluid according to a derivative of a normal line of X directional and Y directional movement of a table. CONSTITUTION:When a nozzle 18 moves along the major toric line 16a of a work piece 16 by a moving amount of a Y table 2 by a motor M1, a control unit 30 detects derivatives of curvature per a unit moving amount by a position signal of the Y table, drives the fifth motor in a nozzle case 20, and controls the nozzle 18 to keep always a constant against the normal line. And also in a moving amount of the nozzle 18 toward X direction, the angle is corrected in the same way. Besides, the nozzle 18 is pressed onto the surface of the work piece 16 by a air cylinder 14, then the distance from the working surface is kept constant by a reaction force of the jet pressure. In this way, the accurate grinding and polishing can be accomplished.

Title: Vertical semiconductor device controllable by field effect and its manufacture
Inventor: TIHANYI JENOE
IPC: H01L29/417
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To control a vertical semiconductor device by such an electric field effect that a gate electrode is insulated from a whole semiconductor substrate by providing a source terminal on the rear surface side of a wafer and a drain terminal and a gate terminal on the front surface side of the wafer. SOLUTION: When a gate voltage is applied across gate electrodes 4, an electric current flows to an n<+> -doped source area 3' from a source terminal S on the rear surface side 12 of a wafer through a bulk area 10 and a vertical trench 13. The electric current further flows to a drain area 2, therefore, to a drain terminal D from the source area 3' through a channel formed below an intermediate cell area 6. On the rear surface side 12 of the wafer, the source terminal S is fixed to a cooling body or a device case 9 without through any insulating layer. Therefore, the earth potential at the source area 3' becomes equal to that at a device. When a copper block is used as the cooling body 9, the heat of a semiconductor substrate 1 can be discharged quickly, because copper has very high thermal conductivity.

A winch 3 is mounted on the outside of the ceiling section 1a, and a wire 6 from a drum 5 of the winch 3 is mounted at the top end of the sleeve 2c. A liquid level detector 7 which detects level of liquid is mounted, and a liquid level signal is sent to the winch 3 to control the position of a BOG take- out pipe 2. A float 10 which follows liquid level may be mounted at the lower end of the BOG take-out pipe 2 instead of the winch 3.

Filed: 1986-11-13
Abstract: PURPOSE:To obtain a semiconductor laser oscillating with high efficiency at a low threshold and having a large optical output by strengthening an optical guide mechanism while forming not only saturable absorbers but also window regions near both reflecting surfaces. CONSTITUTION:Currents injected to a P-type electrode 24 pass through a Zn diffusion region 23 in a cap layer 21 and a third clad layer 20 and flow into the layer 20, but currents are blocked by an n-type GaAs current block layer 15 in the presence of the current block layer 15 being adjacent to the layer 20 and having different electrical polarity, and finally currents pass through a P-type guide layer 14 and a P-type second clad layer 13 from a striped groove 16 bored to the layer 15 and are injected into an active layer 12. Carriers injected into the active layer 12 are diffused in the horizontal and cross direction of the active layer, and gain distribution is formed and laser oscillation is started. In this case, beams oozing out of the active layer 12 and the clad layer 13 are pulled into the guide layer 14 adjacent to the layer 13, and limited by the block layer 15 being adjoined to the layer 14 and having a narrow band gap. Accordingly, fundamental transverse mode oscillation is stabilized.

Abstract: PURPOSE: To make it possible to execute more precise matching of such patterns which vary in the number of repeating points in two patterns and with which the prediction of the probability of the number of these points is not possible by using a contrast probability calculator, contrast point selector and similarity calculator. CONSTITUTION: The respective patterns in, for example, three kinds of first to third plane point patterns are composed of 8 pieces of points 1 to 8. The contrast probability calculator is first used and the contrastable pair is selected by an approximate matching method in order to start the matching of the first pattern and the second pattern. A fuzzy relaxation method is used for calculating the probability that the points 1 to 8 in the first pattern contrast with all the points 1 to 8 of the second pattern is used in the contrast point selector. The contrast probability, average contrast probability, the average distance between the contrast points and radix numeration are used in order to determine whether the two patterns are based on the same origin or not in the similarity calculator.

Title: Catalyst for purification of exhaust gas
Inventor: SUZUKI SHIGEHARU
IPC: B01J23/56
Filed: 1994-11-07
Abstract: PURPOSE: To prevent the deterioration of the purifying performance of a catalyst and to improve the heat resistance by forming the catalyst with an alumina carrier, Pt deposited on the carrier and a cerium oxide layer coating them. CONSTITUTION: Pt 11 is deposited on powder of aluimina 10 as an alumina carrier and the surface is coated with a layer of CeO2 12 to obtain the objective catalyst. Since the alumina 10 is excellent in heat resistance, the Pt 11 on the surface is hardly sintered. Since the carried Pt 11 is surface-coated with the CeO2 layer 12, before it turns into Pt oxide in a lean atmosphere, etc., the CeO2 12 stores oxygen and the formation of Pt oxide is inhibited. Even if Pt oxide is formed, the vapor phase transfer of Pt oxide is blocked by the CeO<2> layer 12. The sintering of the Pt 11 is inhibited because of inhibited aggregation.
