Title: Reduction gear
Inventor: MIURA HIROSHI
IPC: F16H1/32
Filed: 1983-07-21
Abstract: PURPOSE:To decrease a number of gears to a minimum limit so as to reduce backlash, by supporting a gear to a tilt shaft connected to an input shaft and meshing a bevel gear, having a different number of teeth, with this gear while providing engagement parts to be mutually engaged in said gear and an output shaft. CONSTITUTION:An input shaft 1 and an output shaft 2, which are arranged on the same axial line, are turnably supported respectively through bearings 4, 5. Then the input shaft 1 integrally provides in its internal end a tilt shaft 6 having an axial line tilted with respect to the axial line of the input shaft 1, while the tilt shaft 6 supports a face gear 8 having teeth 7 in its one side through a bearing 9. While oppositely facing to the face gear 8, a bevel gear 11, whose number of teeth 10 is different from that of the teeth 7, is fixed to a housing 3. Further the face gear 8 and the output shaft 2 respectively provide concaved parts 13, 14, 16 and convex parts 12, 15, 17 engaged with each other. In such way, a high accurate reduction gear can be obtained by reducing backlash because the number of gears are decreased to a minimum limit.

Title: Motor, and front and rear-wheeled vehicle
Inventor: KURIBAYASHI TAKASHI
IPC: B60K6/26
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To lighten the abrasion of a brush and the occurrence of noise by minimizing the unwanted sliding of a commutator and a brush, in a motor equipped with a commutator and a brush. SOLUTION: Motors ML and MR for driving rear wheels via a rear wheel drive D are equipped with motor shafts 25, stators 26, rotors 27, commutators 28, and brushes 29, and each brush 29 is driven to retreat the vehicle, being supported by an actuator 56. When the motors ML and MR are in operation to generate a driving force or regenerative braking force, the actuator 56 energizes the brush 29 in the direction of protrusion so as to bring it into contact with the commutator 28. When the motors ML and MR are not in operation but are idling with the driving force reversely transmitted from a rear wheel, the actuator 56 drives the brush 29 in a retreating direction to cause it to separate it from the commutator 28, and minimizes unwanted sliding of the commutator 28 and the brush 29, and thus this system can lighten the abrasion of the brush 28 and the generation of noise.

Title: Recording sheet for heat transfer recording medium
Inventor: IWAGAKI MASARU
IPC: B41M5/392
Filed: 1983-07-21
Abstract: PURPOSE:To enable to obtain a coloring matter image with a high transfer density and to maintain the image to be resistant to heat, light or the like, by providing a recording layer comprising a polyvinyl chloride. CONSTITUTION:A recording layer comprising polyvinyl chloride is provided. The polyvinyl chloride is a polymer obtained by irradiating vinyl chloride with light or alpha rays or by subjecting vinyl chloride to suspension, lump, emulsion, homogeneous solution or heterogeneous solution polymerization or other similar polymerization, in the presence of a catalyst consisting of a free radical of an peroxide or the like. An addition of a plasticizer contributes to not only imparting plasticity but enhancing transferring efficiency of a coloring matter and light resistance of a transferred image. A stabilizer, e.g., a metallic soap, is preferably added to the recording layer to prevent decomposition or denaturation due to dehydrochlorination of polyvinyl chloride from occurring. Because of the appropriate polarlity of polyvinyl chloride, the recording layer exhibits excellent adaptability for thermal transfer and exhaustion of an azomethine dye or an indoaniline dye.
