  • Publication number: 20190248240
    Abstract: A display device for a vehicle includes: a dial plate having an indicator portion corresponding to vehicle information on a viewing side; an image display panel disposed on a back side of the dial plate opposite to the viewing side to luminescently display an image; and a light transmissive display plate that includes a reflective portion disposed on the viewing side of the dial plate to reflect a light from a light source to the viewing side. A region of the dial plate, which faces the image display panel, is set to have a light transmission property to transmit the image of the image display panel through the region of the dial plate.

  • Patent number: 8486234
    Abstract: A plating apparatus can form a bump having a flat top or can form a metal film having a good in-plane uniformity even when the plating of a plating object (substrate) is carried out under high-current density conditions. The plating apparatus includes a plating tank for holding a plating solution; an anode to be immersed in the plating solution in the plating tank; a holder for holding a plating object and disposing the plating object at a position opposite the anode; a paddle, disposed between the anode and the plating object held by the holder, which reciprocates parallel to the plating object to stir the plating solution; and a control section for controlling a paddle drive section which drives the paddle. The control section controls the paddle drive section so that the paddle moves at a velocity whose average absolute value is 70 cm/sec to 100 cm/sec.

  • Patent number: 4717697
    Abstract: A method of regenerating hydrous zeolite which contains acetone as well as water after having been used to dehydrate hydrous acetone of the invention which comprises: placing the hydrous zeolite in a closed system in which a heated inert gas is circulated at a pressure more than atmospheric pressures to bring the inert gas into contact with the hydrous zeolite to remove the acetone and water from the zeolite, and condensing the acetone and water in the closed system and removes them from the closed system.The method is in particular useful for regenerating hydrous zeolite which has been used to dehydrate hydrous acetone resulting from the reaction of L-sorbose with acetone to produce diacetone-L-sorbose, and which thus contains acetone as well as about 1000-4000 ppm of water therein.
