Title: Polarizing film
Inventor: SUGIO AKITOSHI
IPC: G02B5/30
Filed: 1986-04-14
Abstract: PURPOSE:To provide high durability and high degree of polarization by adsorbing a dichromatic dye on a PVA film, orienting the same in substantially one direction and subjecting the film to an impregnation treatment of metallic ions and boric acid and subsequent heating treatment in a tense state. CONSTITUTION:The PVA film subjected to the adsorption of the dichromatic dye and orientation is impregnated with the metallic ions and boric acid and is then subjected to the heating treatment in the tense state. A method for immersing the film into a treating soln. is preferable as the method to adsorb the metallic ions and boric acid on the film and is executed at the timing of uniaxially stretching the film after the adsorption of the dichromatic dye and orientation and immersing the film in the tense state into the treating soln. The heating treatment is executed in the tense state for 1-120min at >=90 deg.C. The amts. of the impregnation of the metallic ions and boric acid in the polarizing film are specified to 0.2-20mg in terms of metal per g of the film and 0.3-30mg in terms of boron per g of the film. The polarizing performance, dimensional stability and wet heat resistance are thereby remarkably improved.

Abstract: PURPOSE:To enable to develop more colors than the number of prepared clear color paints, by providing a plurality of clear color coating layers having different colors in piles on the coating surface of a workpiece to be coated. CONSTITUTION:The first opaque coating layer 15 is provided on the coating surface 13 of a workpiece 11 to be coated comprising synthetic resin, metal or the like at need. Clear color paint is then applied onto the surface 19 of the layer 15 to form the second transparent coating layer 17.

Title: Device for irradiating fluid
Inventor: BORUFU DEIITORITSUHI HERORUTO
IPC: B05C9/10
Filed: 1992-04-08
Abstract: PURPOSE: To secure even irradiation to a whole fluid while the fluid flows at the highest flow velocity by providing a mixing means having vanes which change the flowing direction of the fluid in the lateral direction to the axis of a conduit through which the fluid flows. CONSTITUTION: Since a mixing means 21 is held in a conduit 21 and has vanes 22 which disturb the laminar flow of a fluid, all laminas of the flowing fluid reach the external wall of the conduit 11. The mixture generates a movement in the flow and, as a result, all volumetric parts of the fluid reach the external wall of the conduit 11 many times and even irradiation to the whole fluid flowing through the conduit 11 is secured. Simultaneously, a flow is generated in the direction perpendicular to the axis of the conduit 11 and turbulent flows are generated on the wall of the conduit 11, resulting in the prevention of the blockage of the conduit 11. Therefore, a device for irradiating fluid is not only suitable to the pasteurization of water, fluids, etc., but also to the pre-activation of radiation polymerization synthetic resins.
