Title: Manufacture of half-finished enameled ware
Inventor: USUKI RIYUUKICHI
IPC: C23D7/00
Filed: 1980-09-01
Abstract: PURPOSE: To enhance the bonding strength of a film to a substrate steel sheet by thinly coating the sheet with a specified resin and dry or wet applying enamel frit composite powder to the sheet.  
     CONSTITUTION: A steel sheet is thinly coated with methacrylic acid ester or acrylic acid ester resin and used as a substrate. Enamal frit composite powder coated with acrylic acid ester resin is dry applied to the sheet, or a mixture of resin, solvent enamel frit is wet applied to the sheet and dried. The frit particles are usually of 2W50μ. By this method the bonding strength of the resulting film to the substrate sheet is enhanced, and the film is not peeled off by hot and cold bending, drawing and other working. Thus, half-finished enameled ware capable of subjecting to high-degree working is obtd.

Title: Ion implantation device
Inventor: TSUNENARI YOSHITSUGU
IPC: H01J37/317
Filed: 1981-07-31
Abstract: PURPOSE:To suppress temperature increase of a wafer caused during an ion implantation by taking advantage of a cooling caused by radiations by providing conical or wedge-like metallic projections on at least one of the surface of a wafer holder and the wall surface of a process chamber. CONSTITUTION:Radiations 2 sent from a wafer 1 undergo multiple reflection at the surfaces of many wedge-like projections 4 provided on the surface of a wafer holder 3, and at last, are absorbed by the wafer holder 3. As to a process chamber 11 provided with wedge-like projections, since the time during which a wafer 7 faces to the chamber 11 is considerably longer than the time during which ion beams are applied to the wafer 7, the chamber 11 effectively absorbs radiations sent from the wafer 7. As a result, the ion implantation device has excellent characteristics in terms of both the gas discharge rate in vacuum, and a high cooling rate of the radiation absorbing body itself.

IPC: H05K3/46
Filed: 1987-05-20
Abstract: PURPOSE:To accomplish the reduction of the number of the working processes and the improvement of the quality by previously bonding and integrating two metal cores before the pattern formation through a bonding agent such as prepreg, and thereafter forming a pattern by means of an etching. CONSTITUTION:Two metal core are heated and contact-bonded through a bonding agent such as prepreg, and both surfaces thereof are etched to form inner-layer patterns 1a, 1b. Then, the holes are filled with an insulating resin 6', forming a metal core inner-layer plate 7.

Title: Air amount sensing device of internal combustion engine
Inventor: NAGAISHI HATSUO
IPC: F02D45/00
Filed: 1988-05-17
Abstract: PURPOSE:To sense the amount of suction air with good accuracy in any operating condition by correcting the output of a throttle valve opening sensing means so that the amount of suction air calculated by calculation forms a certain ratio to the output of a suction amount sensing means. CONSTITUTION:A control unit 20 calculates the amount of suction air of an engine 1 from the degree of opening of a throttle valve 8 and the number of engine revolutions. The output of a throttle valve opening sensor 9 is corrected so that the amount of suction air calculated through calculation forms a certain ratio to the output of an air flow meter 7. Further the final suction air amount is calculated on the basis of the throttle valve opening after correction and the number of engine revolutions. This allows accurate sensing of the suction air amount in any operating condition without use of a high precision throttle valve opening sensor 9.

Title: Recorder and reproducer of magnetic sheet
Inventor: OOKAWA TATSUMI
IPC: G11B19/04
Filed: 1980-08-30
Abstract: PURPOSE: To ensure the continuation of recording with no actuation of a recording switch, etc. although the recording operation is mistakenly carried out during the reproducing action, by preventing the shift of a recording lever by means of an interlocking member that interlocks a brake device of a turntable.  
     CONSTITUTION: In the reproduction mode, a plunger 12 is attracted to separate a brake lever 11a from a turntable 3. Thus the table 3 starts driving, and at the same time an interlocking member 17 turns round a shaft 16 to move to a position 17 as shown by a chain line. In this case, projections 15a and 15b of the member 17 move to positions 15a' and 15b' as shown by a chain line. As a result, a projection 19' to be engaged of a recording lever 20 engages a hooking projection 15b of the member 17 to prevent the push-in of the lever 20. Thus a recording switch 18 is not closed although a recording button 27 is mistakenly operated. As a result, the reproducing can be continuously performed.

Filed: 1990-05-11
Abstract: PURPOSE:To obtain an image forming device whose structure is simple, whose cost is low and which has a low noise by providing a driving source for outputting driving force and a driving transmitting means for selectively switching and transmitting the driving force of the driving source to a slit member moving means or a lens moving means. CONSTITUTION:By energizing a solenoid 57, the iron core 57a of the solenoid lowers and a lever 62 descends against the pressing force of a spring 63 by a pin 57b engaging with the core 57a. Then, a brake rubber(brake) 64 separates from a gear 55, so that braking force is released. Thereafter, a gear(switching gear) 56 meshes with the gear 55 to move a lens holder 47. Meanwhile, in the case of moving only a moving slit, energizing the solenoid 57 is stopped and the gear 56 is left in a state where it is separated from the gear 55. Thus, the rotational driving force from a driving motor(driving source) M is transmitted from a gear 60 to a gear 61 through the gear 56, and a pulley(for moving a slit) 24 is driven to be rotated. Then, the driving source for moving means for an optical slit for erasing an image frame and the lens moving means is made common, and the device which has the small operational noise and whose cost is low is obtained.

Abstract: PURPOSE:To enable production of carbon or graphite material having a low thermal expansion coefficient and high thermal shock strength by carrying out a graft polymerization of aromatic raw materials of different kinds with a carbonaceous aggregate in a solvent. CONSTITUTION:A carbonaceous aggregate, e.g., coke, carbon black or artificial and natural graphite (preferably having <=1mum particle diameter), an aromatic raw material (e.g., petroleum-based pitch, coal-based pitch, naphthalene or anthracene), a catalyst (e.g., p-toluenesulfonic acid) and an aromatic crosslinking agent (e.g., p-xylylene glycol) are heated (preferably at 100-130 deg.C) to carry out graft polymerization of the aromatic raw material on the aggregate surface. Graft polymerization of an aromatic raw material (e.g., phenol) different from the above-mentioned aromatic raw material with the resultant reaction product is then similarly carried out and the obtained product is separated from the solvent, dried, formed, then calcined to afford the aimed carbon or graphite material.

Title: Laminated x-ray mask
Inventor: NAKAISHI MASAFUMI
IPC: G03F1/00
Filed: 1988-05-20
Abstract: PURPOSE:To prevent oxygen and water vapour resulting in damage of the surfaces of an X-ray mask supporting substrate from coming in contact with an X-ray mask, and to prolong life of the X-ray mask, by a structure wherein the upper and lower surfaces of the X-ray mask supporting substrate, containing boron compound as a main component, for supporting an X-ray absorber pattern are covered with atmosphere interrupting films. CONSTITUTION:The upper and lower surfaces of an X-ray mask supporting substrate 2, containing boron compound as a main component, for supporting an X-ray absorber pattern 1 are covered with atmosphere interrupting films 3. Accordingly, the X-ray absorber pattern 1 or the mask supporting substrate 2 is not in contact with the atmosphere directly, and therefore formation of boron compound can be prevented even though the mask supporting substrate 2 is irradiated with X-ray flux to activate the B series compound contained in the substrate 2. As a result, the mask supporting substrate 2 containing the boron compound as the main component is not acted upon by oxygen and water vapour in the atmosphere, so that a radiation resistant characteristic of an X-ray mask is improved, and the life of the X-ray mask is effectively prolonged.
