Title: Backlash reducing apparatus in gear transmission system
Inventor: TOMITA TAKAO
IPC: F16H55/18
Filed: 1985-09-11
Abstract: PURPOSE:To reduce backlash reliably by constructing the gear in gear transmission system with main and sub-gears while holding a weight member between the holding faces of both gears. CONSTITUTION:The gear 7 is constructed with main gear 17 and sub-gear 18 supported rotatably while coaxially with main gear 17 to hold a weight member 21 between the holding faces 19d, 20d of main gear 17 and sub-gear 18. Since main gear 17 and sub-gear 18 are rotated relatively through the weight member 21 and the holding faces 19d, 20d by the centrifugal force produced through rotation of the gear 7, backlash can be reduced reliably over the entire region for the gear transmission system having high torque fluctuation.

Title: Optical scanner
Inventor: KOIDE JUN
IPC: G02B26/10
Filed: 1989-08-02
Abstract: PURPOSE:To compensate a subscanning-directional spherical aberration and to obtain high resolution by using a member which generates a positive spherical aberration in a subscanning direction for an optical member which converges luminous flux in the subscanning direction. CONSTITUTION:The light emission point of a light source 1, the deflecting surface of an optical deflector 5, and the surface of a scanned body 7 are conjugation points or conjugation lines and the optical member 3 which has refracting power only in the subscanning direction and generates the positive spherical aberration is provided in an optical system which converges luminous flux from the light source 1 linearly in parallel to an optical scanning direction on the deflecting surface of the optical deflector 5. Therefore, the subscanning- directional negative spherical aberration generated by the optical system between an optical deflector 5 and the irradiated body 7 and the subscanning-directional positive spherical aberration of the optical member 3 cancel each other to compensate the spherical aberration. Consequently, the subscanning-directional spherical aberration is compensated to improve the resolution.

Title: Heat transfer pipe with inner surface groove and its manufacturing method
Inventor: MASUKAWA SEIZOU
IPC: B21C37/15
Filed: 1991-08-12
Abstract: PURPOSE:To improve both an evaporation efficiency and a condensing efficiency by a method wherein some large projections are formed at an inner surface of a metallic pipe with a specified spacing therebetween and a pair of small projections are formed between the large projections and inclined toward the large projections. CONSTITUTION:Tubular grooves 16 with their opening width W2 being less than a bottom width W1 are formed between adjoining large projections 12 and small projections 14. In the case where they are used as evaporating tubes, air bubbles are easily formed inside the tubular grooves 16, these air bubbles act as evaporation cores so as to promote evaporation of thermal medium liquid. Accordingly, it is possible to increase the gasification efficiency as compared with that of the heat transfer pipe in which uniform simple grooves are formed in the same pitch. In addition, the extremity ends of the large projections 12 are projected from the inner circumferential surface of a metallic pipe 10 rather than from the small projections 14 and the tubular grooves 16, so that in the case where they are used as a condensing pipe, separation of thermal medium liquid from the extremity ends of the large projections 12 is well performed and a liquid film is hardly formed on this part. Accordingly, there the ratio of exposure of a metallic surface at the extremity ends of the large projections 12 is high, no prohibition of heat exchanging operation between the metal and the thermal medium gas through the liquid film, resulting in that a high condensing efficiency can be attained.

Title: Power transmission mechanism, manufacture thereof and recording device equipped with power transmission mechanism
Inventor: KUDO TAKU
IPC: B65H5/06
Filed: 1992-07-29
Abstract: PURPOSE:To prevent the resuction of the transmission torque even if dust, oil, etc., adhere on a sliding movable surface, by providing a pulley and a belt which has a round section and is installed in slidable manner for the pulley and forming one slidable surface to a fine uneven form. CONSTITUTION:When a roll paper 15 is transported by a conveyor beet 20, pulleys 22 and 23 and a belt 24 slidingly move and transmits the power to the rollers 18 and 19. When a laser printer 4 is used for a long period, the films of dust, oil, etc., are formed on the sliding movable surface between the rollers 22 and 23 and the belt 24. Since fine uneven parts 25 are formed on the sliding movable surface of the belt 24, the surface area of the sliding movable surface can be increased, and the films of oil, dust, etc., on the sliding movable surface can be made thinner. Further, since the contact area of the belt 24 can be reduced, the surface pressure of the sliding movable surface can be increased, and the sliding movable performance of the pulleys 22 and 23 and the belt 24 can be improved, repelling oil, etc.

Title: Resin sealed semiconductor device
Inventor: NAKAGAWA OSAMU
IPC: H01L23/31
Filed: 1981-12-14
Abstract: PURPOSE:To omit an organic film process, by using resin for sealing wherein the impalpable powder of SiO2, with less content of radioactive isotope serving as an alpha ray source, is used as filler. CONSTITUTION:With SiCl4, with less content of radioactive isotope serving as  the alpha ray source, as the raw material, a mass of SiO2 is produced by a hydrolysis due to oxyhydrogen flame or an oxidation due to plasma flame. This is  ground into impalpable powder, and the distribution of grain diameters is made  uniform, thereafter a purification process for removing impurity ions is performed, and accordingly SiO2 impalpable powder for filling can be obtained. When this impalpable SiO2 powder, epoxy resin and additives such as hardener, catalyst or carbon black for coloring are mixed and milled so that the SiO2 impalpable powder is 70wt%, the epoxy resin for sealing mixed with SiO2 can  be obtained. The accumulated number of alpha ray generation for this epoxy resin  for sealing mixed with SiO2 is reduced down to approx. 1/5 of the number of  that of the epoxy resin for sealing mixed with silica which is conventionally used.

Abstract: PURPOSE:To enable a grinding wheel to perform its automatic exchange work preventing sludge, adhering to the internal surface of a cover, from dropping to the surface of a main spindle, by conveying the grinding wheel of a grinding machine to be mounted and removed integrally engaging a grinding wheel cover with a grinding wheel flange. CONSTITUTION:A clamp piece 32, provided in a grinding wheel bed side end part 14a, is disengaged from an engaging piece 23, provided in a cover 21, by turning a grinding wheel cover 21.

Abstract: PURPOSE:To reduce the cost of an instrument and to lessen the manpower thereof by separating a tritium-contg. gas from other gases by means of a fine porous solid membrane and measuring the radioactivity of the separated tritium in real time (simultaneously with the sepn.). CONSTITUTION:One end of a fine porous solid tube consisting of a thin film of ceramics, glass, platinum, hollow synthetic resin, etc., for example, the fine porous thin-walled tube such as 'Vycor(R)' glass tube 10 having 5mm inside diameter, 7mm outside diameter and about 60Angstrom  pore size is closed with an Si rubber plug 16 and the tube 10 is enclosed by a 'Pyrex(R)' tube 14. Both ends of the tube 14 are hermetically closed by annular Si rubber plugs 16. A gas to be measured is put into the tube 14 through a lower introducing port and is discharged through an upper discharge port. The tritium penetrated into the tube 10 in a vacuum section is withdrawn from the open end of the tube 10 and the radioactivity thereof is conducted to a measuring section and is quantitatively determined. The measurement of the concn. of the tritium in various gases or vapors in a short period is thus made possible without the need for concentrating the tritium as liquid.
