Abstract: PURPOSE: A coating agent that contains a water-insoluble polymer or monomer giving a water-insolble polymer by polymerization as an active ingredient, thus preventing the elution of mercury into spittle, when coated on the surface of the amalgam filled in a tooth to form a water-insoluble coating film.  
     CONSTITUTION: The objctive agent contains a water-insoluble polymer or monomers forming a water-insoluble polymer to form a water-insoluble coating film, when it is coated on the surface of the amalgam filled in a tooth. An example of solution of water-insoluble polymer is an ethanol solution of polyvinyl acetate and of monomer type is an α-cyanoacrylate monomer, which polymerizes in the  presence of water to form a water-insoluble polymer film. Further, the coated  films are dried by air blowing or polymerized by light irradiation to form the  water-insoluble film in a short time.

Abstract: PURPOSE:To enhance a heat-resistant by a method wherein, after a nitride of a high-melting- point metal has been formed, a first heat treatment at a comparatively low temperature of a specific temperature or lower is executed before a high-temperature heat treatment at a specific temperature or higher is executed in order to improve a film quality of the nitride of the high-melting-point metal. CONSTITUTION:A p-type silicon substrate 1 in which phosphorus ions have been implanted into a desired region and which has been heat-treated in an atmosphere of N2 is prepared; SiO2 is formed by a vapor growth method; in succession, an insulating film 3 on which phisphosilicate glass containing P2Q5 has been piled is formed. Then, this assembly is heat- treated in the atmosphere of N2; after that, a pattern of a photoresist is formed; a window is opened by making use of this pattern as a mask by a dry etching method. The surface is treated with a diluted-HF-based aqueous solution; after that, a TiN film 4 is vapor-deposited by a DC sputtering method; W is vapor-deposited on it. The laminated W/TiN layers 4, 5 are processed by making use of the photoresist as a mask by a dry etching method; after that, the photoresist is removed. Then, this specimen is heat-treated at 650 deg.C for 30 minutes, and, after that, is heat-treated at 700 deg.C for 30 minutes in the atmosphere of N2. Then, it is heat-treated at 900 deg.C for 30 minutes. Thereby, a reaction of a metal with Si during the high-temperature heat treatments is suppressed by the TiN film; a strain by a stress can be reduced.

Title: Temperature controller for heated indoor in solid fuel type hot air generator
Inventor: KUNIMUNE JIYUNJI
IPC: F24H3/06
Filed: 1980-02-16
Abstract: PURPOSE: To improve a precision of hot air temperature control which is employed to a vinyl house culture or the like, by a method wherein hot air exhausted to a room to be heated is bypassed to a combustion gas exhaust pipe for solid fuel to regulate a hot air amount supplied to the room to be heated.  
     CONSTITUTION: With a blower 2 and a timer 9 actuated, hot air is generated with the heat of briquet stoves 4 and is fed to a culture room through an exhaust pipe 3. With a thermostat actuated resulting from rise of temperature in the culture room, a damper 19 actuates to close an inlet of the exhaust pipe 3, to open a flow path to a bypass line 16, and to exhaust exhaust gas to an exhaust cylinder 13. On the contrary, if temperature falls, the bypass line 16 is closed through the working of the thermostat to increase an exhaust gas amount to the culture room. This enables a hot air temperature control to be performed in a reliable and rapid response manner, and the improvement of temperature management precision for the culture room.

Title: Exhaust pressure control device for internal combustion engine
Inventor: ONISHI HIDEKAZU
IPC: F02B27/06
Filed: 1989-01-27
Abstract: PURPOSE:To make it possible to lower exhaust pressure in a wide operating range by selectively communicating a large or a small resonator chamber with exhaust passages in response to operating conditions. CONSTITUTION:In an operating range in which the engine speed is less than a specified value, the change-over valve 8 of a large volumetric resonator chamber 4 is opened via a controller 14 by means of a drive motor 13, the change- over valve 9 of a small volmetric resonator chamber 5 being closed. And in the engine operating range in which the engine speed is equal or more than the specified value, the change-over valve 8 is closed, the change-over valve 9 being opened. Thus, when each exhaust passage 3a or 3b is communicated with each resonator 4 or 5 through a communicating passage 7, the pressure of exhaust gas exhausted to each exhaust port 2a or 2b is absorbed so as to be damped by means of the resonance interaction of each resonator 4 or 5 in the corresponding revolution range in particular. This therefore permits exhaust pressure to be lowered in a wide operating range, thereby making it possible to contrive to improve an reduction in exhaust noise and also to improve exhaust efficiency.

IPC: B29C37/00
Filed: 1983-02-07
Abstract: PURPOSE:To enable to obtain a high-quality molded article in a comparatively short period of time, by a method wherein a large number of slits is provided in an axial direction by machining on the inside of an end of a heating cylinder, where feed of resin is commenced, a double flight screw is provided with a main flight and an auxiliary flight having a larger pitch than that of the main flight and a cooling cylinder is provided on a heater zone of the heating cylinder. CONSTITUTION:This resin 5 enters into a groove (a) of a screw 2. Although the resin 5 entered into a groove (a') is unmolten resin, as the more the groove (a') moves leftward the more a width of the groove narrows, the unmolten resin is compressed. In this instance, the unmolten resin 5 is entered into a groove (a'') through a gap. When the resin 5 passes through the gap, a temperature of the resin 5 becomes identical with a setting temperature of a heating cylinder 1, an uneven temperature and blotches of color of the resin 5 are eliminated and the resin 5 is turned into a molten resin through compression. It becomes that the resin 5 is turned into the molten resin in the groove (a''), stored in a storage chamber A and injected from a nozzle B. Control of temperatures of each of heater zones H1, H2, H3 is made by cooling cylinders 18, 19, 20. When a temperature of the heating cylinder 1 is raised, it is adjusted by actuating a cooling blower 21.

Filed: 1983-02-09
Abstract: PURPOSE:To extend the service life of a lance for stirring a molten metal and to reduce the cost ratio thereof in the stage of using said lance by spraying mist in the metallic pipe of the lance after the treatment thereby preventing the temp. rise of the lance. CONSTITUTION:A molten metal is stirred and refined by using a lance 3 for stirring a molten metal consisting of a metallic pipe 7 having a gas passage hole 7, and refractories 8 which cover the outside circumference of said pipe and of which the part corresponding to a slag line and the part at the bottom end are formed larger in outside diameter than the other parts. Mist is sprayed in the pipe 7 after said treatment to prevent the temp. rise of the lance 3. The mist spraying is preferably accomplished by spraying mist of about 50-100 gas- water ratio by a small diameter full cone tip to cool efficiently the pipe. The difference in thermal expansion between the refractories 8 and the pipe 7 is thus decreased and the generation of the crack and peeling in the refractories and the bend, etc. of the pipe 7 is prevented, whereby the service life of the laence 3 is extended.
