Title: Manufacture of semiconductor device
Inventor: KOYAMA HIROSUKE
IPC: H01L21/8242
Filed: 1993-03-01
Abstract: PURPOSE:To ensure a high reliability in forming trenches via RIE by forming the trenches in a semiconductor substrate, forming a semiconductor film on their inner faces, and annealing the substrate to getter and trap metal impurities in the semiconductor film. CONSTITUTION:Trenches 14 are formed in a semiconductor substrate 11, and a semiconductor film 15 is formed their inner faces. The substrate is then annealed under specific conditions to getter and trap metal impurities in the semiconductor film 14. For example, a silicon oxide film 12 and silicon nitride film 13 are formed on a semiconductor substrate 11, and after patterning trenches 14 are formed in the substrate 11 by RIE. A semiconductor film 15 is formed on the side and bottom faces of the trenches 14, and the substrate is annealed at approx. 600 deg.C for approx. 300min. Thus metal impurities implanted in the sidewall and bottom faces of the trenches 14 is gettered and trapped in the semiconductor film 15. The semiconductor film 15 is then converted into an oxide film 16 by wet oxidation, so that the metal impurities in the semiconductor film 15 is taken in the oxide film 16.

Filed: 1979-04-03
Abstract: PURPOSE:To enhance the fixing property of toner images on recording paper by disposing a light transmittable electrode to one portion of the flash light radiation region of a flash discharge tube and a counter electrode interposing recording paper  between and applying high-frequency voltage between the both electrodes. CONSTITUTION:NESA glass 5 coated with a tin oxide thin film 5a is disposed at the opening of the reflecting plate 4 covering a flash discharge tube 1 and a guide plate 6 to become a counter electrode is disposed in opposition to this and is grounded. Then, when recording paper 7 is detected by a photo transistor 8b, a switching circuit 12 conducts and high-frequency pulses are applied to a high- frequency switching circuit 10, by which the high-voltage plus voltage having been high-frequency chopped is applied to the thin film 5. Hence, energy is given to the recording paper 7 and the evolution of heat occurs in that portion. With the recording paper 7 having been preheated in this way, the flash of the discharge tube 1 is absorbed and the toners of a molten state fit well, thus good fixing is accomplished.

Title: Forming method for resin film on inwall surface of pipe or vessel in metal, glass, paper or wood
Inventor: MIDORIKAWA YOSHIO
IPC: B29C63/00
Filed: 1980-03-31
Abstract: PURPOSE: To form a uniform resin film on an inwall surface of a pipe or a vessel easily by a method wherein a hollow molding in synthetic resin is inserted to the inwall surface of the pipe or the vessel, and expanded and attached on the inwall surface by hot air.  
     CONSTITUTION: A molding pipe 2 in synthetic resin is inserted into a pipe 1 in metal, glass, paper or wood. An opening port of one end is sealed by a plug 3, and an opening port of the other end is sealed by a plug 4 into which an air introducing pipe 5 is penetrated. When air having a temperature, at which the synthetic resin of the molding pipe 2 extends and expands, is sent into the molding pipe 2, the molding pipe 1 contacts with an inwall surface of the pipe 1. Air pressure is increased to some extent, and a temperature of the air is elevated up to a temperature, at which the synthetic resin of the molding pipe 2 is plasticized and softened. Thus, the molding pipe 2 closely adheres on an uneven surface of an inner surface of the pipe 1 by the viscosity. When the molding pipe 2 is cooled, a film 2a is formed. Lastly, the film as an object is obtained when air is extracted together with the plug.

Abstract: PROBLEM TO BE SOLVED: To provide a coated layer having excellent long-term adhesion in sea water by heating, before adhering, a part corresponding to a curved part of a steel sheet pile of a corrosion-resistant polyolefin sheet. SOLUTION: A heavy corrosion-resistant coated steel sheet pile is composed by forming a modified polyolefin layer 3 on a sheet pile 1, where blasting and formation treatment, and pretreatment of a primer layer 3 are applied, and adhering a sheet composed of a corrosion-resistant polyolefin layer 4 thereon. Before coating the corrosion-resistant polyolefin sheet, hot air is blasted to a part to be heated, that is, a sheet part to be adhered to a curved surface part of the steel sheet pile 1, using a heat source such as an infrared heater or the like. Heating temperature is (mp-60)<=T<=(mp-5), where in mp ( deg.C) is melting point of a resin composing the corrosion-resistant polyolefin sheet, and T ( deg.C) is a maximum temperature of the sheet heated part. If the heating temperature is over (mp-5), the sheet melts before the adhering process.  If the temperature is lower than (mp-60), improving effect of long-term adhesion developed by heating is smaller.

Title: Endless belt coating and releasing mold and cleaning and removing method
Inventor: MATSUO MINORU
IPC: B29C41/04
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To ensure the releasability of coated film and prevent the coated film from breaking and a peeling residue from remaining by a method wherein a releasing layer is formed with a fluorine-based resin on the inner surface of a coating and releasing mold. SOLUTION: By forming a releasing layer made of a fluorine-based resin on the inner surface of a cylindrical coating and releasing mold 1, a favorable releasability is obtained between a coated film 3 and the mold 1. Since the coated film 3 bonds to the coating and releasing mold 1 and does not break, the reuse of the coating and releasing mold becomes easy. When a peeling residue has remained, a coating liquid made of the same material as that of the peeling residue is coated thicker than usual on the peeling residue and heated and hardened. The peeling residue and the top coated thick recoated film 4 turn into an integral body since the residue and the film 4 have the same material. Simultaneously with the removal of the recoated film 4, the peeling residue is also removed.

Abstract: PURPOSE: The titled medicine containing a specific reduced glycylrrhetinic acid as a main constituent without side effects of the glycylrrhetinic acid.  
     CONSTITUTION: A medicine containing olean-12-ene-3β, 30-diol expressed by formula I as a main constituent. The glycylrrhetinic acid of formula II is effective  against peptic ulcer, inflammation and allergic diseases clinically; however, has an  Na storing and K diuretic action by the electrolytic action thereof, and particularly  exhibits so-called pseudoaldosteronism, e.g. hypertension, hypokalemia or edema,  by the abnormal electrolytic metabolism. The abnormality is believed to inhibit the  activity of reductase conducting the metabolism of aldesteron by carrying out the Δ 4 - 5α and 5β-reduction of the aldesteron in the liver. The examination on the glycylrrhetinic acid derivative of formula II showed that the compound of formula I had a  drug action equal to or more than that of the glyclrrhetinic acid without causing the  side effects thereof.
