  • Light distribution control device
    Patent number: 7241038
    Abstract: In this light distribution control device in order to provide a vehicular lighting fixture for an Adaptive Frontlighting System (AFS) in which a lot of light distribution patterns can be set without making the entire lighting fixture larger, beams which link said movable substrates to said inner frames and beams which link said inner frames to said outer frame are mutually orthogonal, and a light distribution pattern is set by deforming under torsion the beams which link said movable substrates to said inner frames and the beams which link said inner frames to said outer frame, and swinging each of said movable substrates with respect to said outer frame in the biaxial directions independently.
    Type: Grant
    Filed: April 15, 2005
    Date of Patent: July 10, 2007
    Assignee: Hitachi, Ltd.
    Inventors: Irizo Naniwa, Kazutaka Satou, Masaya Horino, Tatsuhiko Monji, Ken Ohsumi

  • Liquid developing device, method of it's maintenance and the method of recovery of supplemental fluid from the liquid developing device
    Patent number: 6539188
    Abstract: A liquid type development device for developing an electrostatic latent image formed on image-holding equipment by using liquid developer made of a highly insulating solvent and toner particles dispersed in the solvent has a liquid developer tank detachably situated in a cartridge; and at least one supplementary liquid tank containing supplementary liquid to be added to liquid developer contained in the liquid developer tank so as to keep the concentration of nonvolatile components in the liquid developer constant. Further, when the used development cartridge is recovered, and another new development cartridge is bought, a discount price privilege for the newly bought development cartridge is given to a user who has turned in the used cartridge.
