  • Patent number: 10808803
    Abstract: A speed reducer includes a gear, a pinion gear, a movable portion holding the gear so as to be rotatable around a first axis, and a movable portion holding the pinion gear so as to be rotatable around a second axis non-parallel to the first axis. The gear has an annular power transmission portion surrounding the first axis on one side in a direction along the first axis. The pinion gear has a power transmission portion facing the power transmission portion and transmitting rotational torque on an outer periphery. The movable portion has a bearing portion holding the pinion gear inside the power transmission portion and a bearing portion holding the pinion gear outside the power transmission portion.

  • Patent number: 4388630
    Abstract: An ink liquid supply system for an ink jet system printer includes a constant flow rate pump and a pressure accumulator for removing a pressure pulsation or ripple created by the constant flow rate pump. In order to stabilize the constant flow rate operation and to shorten the preparation period of the system when the system operation is started, a temperature compensation or sensitive system is provided for varying the ink liquid pressure within the pressure accumulator. The temperature compensation system includes a bimetal element for varying the pressure to be applied to a resilient member included in the pressure accumulator. The pressure adjusting operation is continuously conducted even when the ink jet system printer does not operate.

  • Patent number: 4373164
    Abstract: A charge condition detection system is provided in an ink jet system printer of the charge amplitude controlling type in order to synchronize the application of the charging signal with the droplet formation timing. The charge condition detection system includes a metal member physically connected to the ink liquid to be supplied to an ink droplet issuance unit, and a capacitor electrically connected to the metal member. When the ink droplet is properly charged, the charge amount corresponding to the charge carried by the ink droplet is accumulated on the capacitor. By measuring the voltage appearing across the capacitor, the charge condition of the ink droplet is detected.

  • Patent number: 4315322
    Abstract: In an improved system for loading new microfiches, or updating previously stored microfiches, in a microfilm cassette library; a registration mode is provided whereby a keyboard operator can register keyword a and other index information for specific frames while these microimages are concurrently being projected on a viewing screen. Structures are included for receivingand holding fiches or cassettes being registered, for positioning frames for optical projection, and for reading magnetically encoded fiche identity data. Both buffer memory and file memory means are provided for storage of frame address information including cartridge identity, microfiche identity, X and Y axes coordinates, and other index data. Microcomputer means are provided for overall control of the registration of new fiches and for retrieval of same.
