Title: Silver halide photosensitive material
Inventor: HAGA YOSHIHIRO
IPC: G03C7/20
Filed: 1983-02-15
Abstract: PURPOSE:To prevent fog due to pressure by adding substantially round monodispersed silver halide grains to a silver halide emulsion layer highest in photosensitivity in plural silver halide emilsion layers constituting photosensitive layers. CONSTITUTION:Photosensitive layers formed on a support have plural silver halide emulsion layers different in photosensitivity but substantially equal in color sensitivity and they are arranged preferably in the order of red, green, and blue sensitive layers on the side of the support, and also arranged so as to render, preferably, the layer located farthest from the support highest in photosensitivity, and the layer nearer to the support lower in sensitivity. When, needed, nonphotosensitivie layers are formed between the silver halide emulsion layers. The monodispersed highly photo sensitive silver halide grains are of, e.g., silver bromide, iodide, or iodobromide. Said silver halide photosensitive material can provide pressure fog.

IPC: H01M8/02
Filed: 1982-02-16
Abstract: PURPOSE:To eliminate the camber of a gas separation plate during a carbonization process by dividing the side edge having the seal surface of the gas separation plate into two in a thickness direction so that the binder mixing ratio at seal section sides is made larger than that at feed groove section sides. CONSTITUTION:The gas separation plate 1 of a matrix type fuel cell is formed by heat pressing the mixed powder of carbon and binder and by carbonization processing the binder. Hydrogen gas feed grooves 3 are arranged with both side edge seal surfaces 2 being left on one surface, and air feed grooves 5 are arranged in a direction intersecting with the hydrogen gas feed grooves 3 with both side edge seal surfaces 4 being left on the other surface. Then, individual side edges with the seal surfaces 2, 4 are divided into two in a thickness direction so that the binder mixing ratio at the seal surfaces (a), (b) is made larger than that at the feed groove section sides. Therefore, the separation plate 1 is prevented from generating a camber during a carbonization process, and the assembling characteristics can be remarkably improved.

Filed: 1979-03-02
Abstract: PURPOSE:To prevent choking of an ink jet nozzle by applying pressure forcibly from the inside of the nozzle to the tip thereof just before recording so as to push out the ink remaining in the tip of the nozzle. CONSTITUTION:When the electric current inputted in an electromagnet 12 is reversed for a fixed time and S-pole is formed on the face b just before recording, a force attracted in the direction of the electromagnet 12 acts on a permanent magnet 14, thereby a spool 13 fixed on the same axis with the permanent magnet 14 being transferred in the direction of X.

Title: Liquid crystal display element
Inventor: TASHIRO YOSHIZO
IPC: G02F1/1335
Filed: 1986-02-07
Abstract: PURPOSE:To prevent a background color from being colored at the observation from the maximum contrast direction by constituting a liquid crystal display element so that a dichromatic coloring matter contained in the liquid crystal shows a complementary color with the background color and the angular shear between the long axis direction of coloring matter molecules and the light absorbing axis direction is 10-20 deg.. CONSTITUTION:At the position of no voltage impression, a light beam from a back- light 1 is transmitted through a color filter 11 and the 1st polarizing plate 9, but optically rotated by the liquid crystal 7 in a TN type liquid crystal cell 2, so that the light beam can not be transmitted through the 2nd polarizing plate 10 and becomes dark background. Since the angular shear between the long axis direction A of the coloring matter molecules and the light absorbing axis direction B is set up to 10-20 deg., the coloring effect of the dichromatic coloring matter 8 is increased when the liquid crystal display surface is observed from the inclined direction. As the result, an interference color in the cell 2 or the color of the color filter 11 is colored more blue by the dichromatic coloring matter 8. Thereby, the background color can be formed as pure black by mixing red-like background color with the color of the dichromatic coloring matter 8 which are compremetary relation each other.
