  • Patent number: 11933980
    Abstract: The information display apparatus configured to display video information of a virtual image on a reflecting surface of conveyance includes: a display configured to display the video information; and a virtual image optical system configured to display a virtual image at a front of the conveyance by reflecting light emitted from the display by means of the reflecting surface. The virtual image optical system includes a concave mirror and an optical element. The optical element is arranged between the display and the concave mirror, and is configured to correct distortion of the virtual image obtained so as to correspond to a viewpoint position of a driver on a basis of a shape of the concave mirror and a shape of the optical element. The information display apparatus further includes a virtual image double image conversion reducer configured to reduce double image conversion of the virtual image.

  • Patent number: 11921287
    Abstract: The information display apparatus has a housing with an opening and a transparent cover formed on the opening, the housing includes image-light generating means configured to generate image light that displays the image information and an optical system configured to allow a driver of the vehicle to recognize image information based on the image light from the image-light generating means as a virtual image in front of the windshield. When S-polarized light on the windshield is assumed to be a first polarized wave while polarized light that orthogonally crosses the S-polarized light in a polarizing direction is assumed to be a second polarized wave, the image-light generating means is configured to generate the image light made of the first polarized wave, and a transmittance/reflectance control means blocks a part of the first polarized wave and the second polarized wave of incident external light entering the housing from the opening.

  • Patent number: 4068754
    Abstract: An apparatus for the purpose of piling up a prescribed number of plate-shaped articles in trim order, said apparatus comprising chain conveyers which are installed below a receiving member for temporarily supporting the plate-shaped articles and accommodated in a frame, chutes which are disposed on both sides of said conveyers, and fore adjusting plates and rear adjusting plates which are disposed to be perpendicular to the direction of progress of the chain conveyer and capable of reciprocating between a vertical position and an outwardly inclined position relative to said direction of progress of the chain conveyer, whereby said piling-up work can be performed by driving said adjusting plates.

  • Patent number: 4028211
    Abstract: An apparatus for automatically replacing anodes and cathodes disposed alternately in an electrolytic cell used for the electrolytic refining of a metal. The anodes are each formed with a pair of recesses on opposite edges of the upper end thereof, and a central cutout having a sufficient depth is formed between the recesses of the anodes. The apparatus comprises a pair of parallel rods engageable with the recesses of all the anodes and a plurality of clamping units adapted for clamping the cathodes on opposite sides of the upper end without engaging the anodes during clamping movement by virtue of the provision of the cutout in the anodes. Thus, the anodes and cathodes can be automatically loaded into and unloaded from the electrolytic cell while maintaining the predetermined inter-electrode distance required for the electrolysis of the metal.

  • Patent number: 3953312
    Abstract: A method of peeling the electrodeposited metal plate off the cathode base plate by inserting a wedge downward in the fine void formed previously between said cathode base plate and electrodeposited metal plate by hammering the surface of the upper edge of said electrodeposited metal plate, wherein a low pressure fluid is jetted from the vicinity of the tip of the wedge toward said fine void prior to insertion of said wedge therein.
