Title: Carrier for developing electrostatic latent image
Inventor: AOKI MITSUO
IPC: G03G9/09
Filed: 1987-10-30
Abstract: PURPOSE:To obviate an increase in the resistance of a developer even if resins are coated on a carrier surface and to obtain an image having excellent medium contrast reproducibility by incorporating plural kinds of the resins which are incompatible with each other and fine conductive powder into a coating layer. CONSTITUTION:Plural kinds of the resins A, B which are incompatible with each other and the fine conductive powder 2 are incorporated into the coating layer of the carrier provided with the coating layer on the surface of core material particles 3. Since the fine conductive powder 2 is concentrated to the boundary face of the resin A and the resin B (incompatible with the resin A), a conductive circuit is formed on the surface of the carrier 1 and the carrier resistance is decreased; in addition, the smaller amt. of the fine conductive particle is necessitated. The increase in the resistance of the developer is thereby obviated even if the resins A, B are coated on the surface of the carrier 1. The image having the extremely good medium contrast reproducibility is thus obtd.

Title: Engine power transmitting structure
Inventor: TOSHIKUNI NOBUYUKI
IPC: F16H55/14
Filed: 1987-10-30
Abstract: PURPOSE:To effectively subside gear noise by providing elastic bodies, in which a transmitting part and a passive part are brought in contact with each other when the gear transmission is loaded, between the rotary bodies placed on the engine side and on the transmission side, respectively. CONSTITUTION:Steel coil-springs 11 and 13, whose both ends are supported by resin-made, spring shoes 9, 10, and 12, are placed between a transmitting part 6 and a passive part 7, so that the rotation of an input shaft 4 is transferred to an input gear 5 via the springs 11 and 13. When the gear-transmission is loaded, the rotation of the input shaft 4 is directly transferred from the input shaft 4 to the input gear 5, owing to a contact between the transmitting part 6 and the passive part 7. When the gear-transmission is unloaded, the rotation of the input shaft 4 is transferred to the input gear 5 via the springs 11 and 13. Accordingly, rotational vibration of the input shaft 4, which is caused by the engine idling, is absorbed by the springs 11 and 13, lest the vibration should easily be transferred to the input gear 5. Thus, the gear noise can effectively be subsided.

Abstract: PURPOSE:To attain to enhance not only printing quality but also the life of a printing head by smoothly performing the insert of a sheet like medium, by changing the gap between a platen and a printing head by revolving the platen by predetermined quantity at the time of printing. CONSTITUTION:Because a platen shaft 2 is eccentric by a distance (l) with respect to the axis O of a platen 1, the platen 1 revolves as shown by a two- dotted line to allow a sheet like medium 15 to approach a printing wheel 12. At this time, if the sheet like medium 15 is levitated from a guide member 14, the sheet like medium 15 is shifted from a guide member 14 to generate such an obstacle that the guide member 14 is hooked with the printing wheel 12 and, therefore, the platen 1 revolves so as to press the lower end of the sheet like medium 15 to the bottom surface of the guide member 14. When the sheet like medium 15 approaches the printing wheel 12 by revolving the platen 1, the printing wheel 12 is rotationally driven by a type selection motor 11. By this method, the selection of a type is performed and the selected type is allowed to impinge against the sheet like medium 15 on the platen 11 by a printing hammer 13 through an ink ribbon to perform printing.
