Abstract: PURPOSE:To secure the safety, maintain a mildew-proofing effect for a long period of time and simply and inexpensively carry out the application by spraying a metallic film in specific thickness onto a wall surface, etc., at a low temperature and forming a mildew-resistant film. CONSTITUTION:The pseudo-alloy or alloy of zinc, copper or aluminum and zinc is sprayed at a position, where mold is easy to propagate itself, onto a building in thickness of 30-120mum through low-temperature spray application, thus forming a metallic film 3. When spray application is conducted onto a wall surface, etc., on which a spray-coated film is difficult to be formed directly, a surface is coated previously with a surface roughening agent, and a surface roughening agent layer is shaped onto a coated surface. The surface roughening agent is manufactured by mixing ceramic particles having a diameter of 10-150mum into a thermosetting or thermoplastic liquid resin. The metallic film 3 in thickness of 30-120mum is formed through the same low-temperature spray application after drying. Accordingly, the specified metallic film 3 intercepts moisture and a nutrient required for the propagation of mold while metallic ions work to the spores and mycelia of mold, thus preventing mold.

Title: Load responsive control and method of the same
Inventor: RANDOORU SHII GUREI
IPC: H02P9/30
Filed: 1990-09-05
Abstract: PURPOSE: To protect a generator against overloading by providing a regulator with a time lag through a regulation loop thereby limiting response of the generator to the fluctuation in the steady state of a load. CONSTITUTION: A regulator 16 has an input 20 connected with the positive terminal of a battery which applies a supply voltage VBAT to the input of a level shifter 22 generating a reduced voltage V22 at the first input of a summing junction 23. Second input of the summing junction 23 is connected with the first output of an oscillator 24 generating a saw-tooth voltage VOSC. The voltage VOSC must have a period shorter than the time constant of the inductive field winding of a generator 14 and since it is generally in the range of 200-300mS, the oscillator 24 is set to operate generally at a frequency of 200Hz (5mS). Consequently, a control signal from the regulator 16 emerges in real time for the response time of the generator 14.

Title: Filter
Inventor: OTANI TETSUYA
IPC: F01N3/02
Filed: 1988-09-20
Abstract: PURPOSE:To suppress the deterioration of a filter by its clogging and enable its long-term use by forming the filter of a ceramic filter, a ceramic mount, and an oxidizing catalyst. CONSTITUTION:A filter 10 is entirely formed into a rectangular plate by a porous ceramic filter 11 having one surface used as a filter face 20, a ceramic mount 12 integrally bonded to the other surface, and an oxidizing catalyst 13 supported within the ceramic filter 11. Hence, the soot accumulated within the ceramic filter 11 is burnt at an exhaust gas temperature by the oxidizing catalyst 13, and the heat by the burning of the soot is transmitted to the ceramic mount 12 to suppress the burning of the ceramic filter 11. Thus, as the exhaust gas temperature is increased in a high load running of an engine, the burning of the soot is accelerated to suppress the deterioration of the ceramic filter 11 by its clogging. The frequency of washings by the reversed air flow is reduced, and the filter can be used for a long time.

Title: Dielectric isolation method
Inventor: MATSUO ICHIRO
IPC: H01L21/76
Filed: 1984-11-08
Abstract: PURPOSE:To form a fine and flat dielectric isolation region easily without photomasking process by a method wherein a semiconductor substrate formed of an insulating film inside an isolating groove is rotated on a plane in parallel with the surface thereof while polycrystalline silicon thin film is obliquely evaporated on the surface to close an opening of isolating groove for thermooxidation of the polycrystalline silicon thin film. CONSTITUTION:Inside of an isolating groove 13 is selectively oxidized forming an SiO2 film 14 to form an isolated island region. A silicon substrate 11 is rotated in a plane in parallel with the surface of silicon substrate within a vacuum chamber while evaporated particle bundle of polycrystalline silicon enters meeting the surface of substrate 11 at an angle alpha preferably less than 15 degree. Elapsing specified period of time, an opening of groove 13 is closed by a polycrystalline silicon film 23 to form a cavity 131. The polycrystalline silicon film 25 is oxidized to be converted into an insulating film from an SiO2 film 24. Through these procedures, the groove width may be minimized for high integration since a dielectric isolation region with flat surface may be formed without additional photomasking process.

Title: Manufacture and treatment of semiconductor device, laser beam device therefor and semiconductor device obtained by using same
Inventor: OKAMOTO YOSHIHIKO
IPC: H01L21/768
Filed: 1988-09-19
Abstract: PURPOSE:To prevent the development of cracks when wiring is being formed by performing wiring formation while repeating laser beam scanning in the orthogonal direction to the extension direction of wiring when wiring is formed on the surface of a sample. CONSTITUTION:Wiring formation is performed by making a laser beam LB scan in the orthogonal direction to the extension direction of jumper corrective wiring 94. In such a case, scanning of the laser beam LB in the orthogonal direction (direction X) is realized by a modulation unit 16, that is, amplitude formed with an AO modulator. On the other hand, the movement of the laser beam LB to the direction Y is realized relatively by moving an XY stage 7 on which a sample 13 is placed in the direction Y at low speed. When jumper corrective wiring 94 is formed, the high strength of coupling in metal molecules in the orthogonal direction to the extension direction of wiring is obtained by causing the laser beam LB to scan in the above direction. Consequently, the development of cracks is prevented when wiring is being formed and a highly reliable wiring correction is obtained.

Title: Printing head
Inventor: UCHIKAWA TADAYASU
IPC: B41J2/295
Filed: 1986-10-02
Abstract: PURPOSE:To obtain a high reliable small sized printing head of a high speed without failure of a piezo-electric element, by a method wherein a second plate spring is provided between a first plate spring having a printing wire as an output terminal and the piezo-electric element as a drive source, and the piezo-electric element is compressed with the second plate spring. CONSTITUTION:When a voltage is impressed on a piezo-electric element 4, the piezo-electric element 4 causes a displacement motion of a high speed and the displacement is transmitted to a second plate spring 3. Further, the motion is simultaneously transmitted from the second plate spring 1 to the first plate spring 2, and the plate spring 2 carries out free flying motion. Therefore, a printing wire 1 kept by the plate spring 2 strikes paper 9, and an ink ribbon 10 and a character is drawn by a dot matrix. Thereafter, the printing wire returns to the original position by the repulsion of printing motion and the restoring force of the spring. Then though the plate spring 2 flies free, the piezo-electric element 4 is always compressed by the plate spring 3 and the tensile stress of the piezo-electric element 4 generated at a time point when the plate spring 2 flies free is pressed thereby. Therefore, the rupture of the piezo-electric element 4 vanishes.

Title: Method and apparatus for treating clinker ash for coal combustion furnace
Inventor: KINOSHITA TAKESHI
IPC: F23J1/02
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To achieve a removal of a solid component in circulation water and a lowering of the water content of clinker ash to be taken out by improving a continuous clinker ash discharge method using a submerged conveyor. SOLUTION: Clinker ash discharged continuously from a submerged conveyor 3 is turned to a slurry and transferred into a filtering/dehydration tank 7 having a filtered water leading port 13 with a screen mounted on a bottom part using a centrifugal type ash pump 5 to be stored. This facilitates the transferred even when the filtering/dehydration tank is located at a distant point. The slurry is filtered using the clinker ash 12 settling in the filtering/dehydration tank as filter bed to separate the clinker ash from water. An agitation is performed by blowing water in the filtering/dehydration tank oppositely and then, the clinker ash is settled again to make a filter material thereby improving the filtering efficiency preferably.  The concentration of a solid component in circulation water is reduced to about several ppm thereby decreasing loss in pumps, heat exchangers, valves and pipings significantly.

Title: Tape carrier
Inventor: HARA KAZUMI
IPC: H01L21/60
Filed: 1991-09-17
Abstract: PURPOSE:To remove a runner and gate without adding a force to a tape carrier by a method wherein a resin which is not closely adhered to an epoxy resin to be used for transfer-molding is applied to a contact part with the runner and gate. CONSTITUTION:A resin 3 which is not closely adhered to a thermo-setting epoxy resin to be used for transfer-molding is applied to a contact part or a region containing the contact part, or a region of a part of the contact part between a runner and gate 4 which is formed at transfer-molding and a tape carrier 1a. Thus, when the runner and gate 4 is removed from the tape carrier 1a by a jig or manually, as the runner and gate 4 comes into contact with the resin 3 which is not closely adhered to the epoxy resin, the tape carrier 1a can be removed without distorting it by adding a force thereto. Accordingly, damages such as a distortion, a lead curve, a lead cutting, or the like are not caused to the tape carrier.
