Title: Planetary gear device and speed reducer for engine starter using the same
Inventor: INNAMI TOSHIYUKI
IPC: F02N15/02
Filed: 1993-10-26
Abstract: PURPOSE:To improve increase/reduction speed ratio and reduce the number of parts so as to facilitate assembling performance. CONSTITUTION:A planetary gear 3A is produced by providing a bearing part 13A between large and small dia. gears 4A, 5A and two gears and intergrally molding a sintered metal therewith. The dia. of the part 13A is larger than the dia. of the tooth tip circle of the gear 5A while the bearing 14A is inserted into the bearing part 13A without being interfered with the gear 5A. The planetary gear 3A into which the bearing 14A is inserted into a bearing hole 15A arranged at a carrier 7 integrally formed with a carrier shaft 1. A sun gear 2 positioned at an end of the input shaft 1 is meshed with the gear 4A of the gear 3A and the gear 5A of the planet gear 3A is meshed with an internal gear 6 fixed. The increase/decrease ratio is thus improved and the number of part can be reduced for assuring a simple assembling.

Title: Molecular beam epitaxial growth method
Inventor: MASHITA MASAO
IPC: H01L21/20
Filed: 1984-12-20
Abstract: PURPOSE:To suppress variation in carrier concentration at the regrowth interface by thermally vaporizing a V-group or III-V thin film as a protection film immediately before the regrowth in case other crystal is caused to grow again. CONSTITUTION:On the occasion of executing an adequate processing under the atmospheric condition to a compound semiconductor crystal consisting of III group and V group formed by the molecular beam epitaxy growth method and then forming other crystal again on such crystal by the molecular beam epitaxy method, a thin film of V group substance as the composition element and a thin film of III-V compound forming a compound semiconductor crystal are sequentially stacked and these are caused to grow continuously as a protection film and this protection film is vaporized at the time of regrowth and thereafter the desired crystal is formed by growth. Since the III-V crystal is protected by the V group and III-V thin film which are thermally and chemically stable before it is taken out into the atmospheric condition, it is not contaminated by the atmospheric condition and the protection film consisting of said two layers can be easily and thermally vaporized at the time of regrowth. Therefore, the pure interface having no modulation of carrier concentration can be obtained at the regrowth interface.

Title: Image forming apparatus
Inventor: TAKAGI OSAMU
IPC: G03G15/05
Filed: 1993-10-27
Abstract: PURPOSE:To provide an image forming apparatus in which an efficiency of toner flow generation is high and a low voltage drive is performed by providing destaticizing means for destaticizing toner supplied to toner flow control means by toner supply means. CONSTITUTION:Since an electric field is not formed, toner 16 on a carrier roller 14 is not effected by an electrostatic force, and hence toner retained on the roller 14 without passing apertures 6 is scraped by a brush of a recovery roller 15, adhered thereto, and rapidly destaticized, the toner adhered to the brush is stripped by a recovery blade 19, and recovered by a toner reservoir 21. The toner recovered by the reservoir 21 is mixed with unused toner and agitated by rotation of an agitator 17, and partly also adhered to a supply roller 12. Since the recovered toner is effectively destaticized at the time of stripping by the roller 15, even if it is immediately supplied to the roller 14 through the roller 12, it is suitably charged by a layer regulating blade 18, and hence no problem in chargeability occurs.

Title: Production of stretched film or sheet
Inventor: SAKAMOTO KUNISUKE
IPC: B65H23/028
Filed: 1988-10-25
Abstract: PURPOSE:To eliminate surface damage and to enhance uniformity by allowing a synthetic resin film to run in such a state that both end parts thereof are graphed between two rows of chucks running on turn rails arranged so as to differentiate the running distances of the chucks. CONSTITUTION:When the curvatures of inner and outer peripheral turn rails are respectively set to r2 (distance o-a'), r1 (distance o-a) and an angle of a circular arc is set to theta (angle a, o, b), inner and outer chucks are allowed to run at the same speed. Whereupon, the outer chuck is delayed from the inner chuck and the magnitude of delay becomes theta (r1-r2). Since r1-r2 is the width of a tenter, the delay of the outer chuck becomes theta-times the width of the tenter. When theta=1 radian (57 deg.) is just set, a continuous film whose molecular orientation is 45 deg. is obtained. By changing the angle of the circular are or the relative running speeds of the inner and outer chucks if necessary, the angle of the molecular orientation of the film or sheet 2 can be changed arbitrarily. When the film 2 obliquely oriented is folded double to be adhered, a laminated film or sheet crossed in stretching orientation and almost uniform in longitudinal and lateral strengths can be obtained.
