Title: Color printing method
Inventor: ISHITOBI YOSHIMITSU
IPC: G03G15/01
Filed: 1983-02-25
Abstract: PURPOSE:To make clear the boundary between different-color areas and to improve the quality of color print by making a fine-distance shift in latent image position on electrostatic recording paper during color printing. CONSTITUTION:Latent images Q1 and Q2 of the inverted signal R' of the red video signal R of a CRT 1, and they are developed with toner in cyan and fixed. The latent image of an inverted signal G' for green is shifted slightly from the images Q, etc. For this purpose, the deflecting device for the raster of the CRT is adjusted to make both a horizontal and a vertical slight shift. Then, a latent image Q3' is developed with magenta toner and fixed. Further, a latent image for a picture by an inverted signal B' for blue is also formed while shifted slightly, and the image is developed thereupon with yellow toner and fixed. Thus, toner particles in cyan, magenta, and yellow are present together where the latent image boundaries shift to form a black part. Therefore, the bleeding of colors is reduced to obtain a clear picture.

Title: Production of laminated sheet
Inventor: KASAI YOSHIHARU
IPC: B32B27/04
Filed: 1982-02-28
Abstract: PURPOSE:To produce a flame-retarding laminated sheet with good surface smoothness, by using bases impregnated with a flame-retarding unsaturated polyester resin solution whose viscosity is controlled with a flame retardant-containing monomer. CONSTITUTION:In a process for producing a laminated sheet by preparing resin- impregnated bases formed by impregnating bases with a flame-retarding unsaturated polyester resin solution and laminating these bases; the viscosity control of the flame-retarding unsaturated polyester resin solution is effected by using a monomer (e.g., styrene) containing a flame retardant (e.g., tribromophenoxyethyl acrylate). It is possible to control the viscosity at a value suitable for the preparation of bases without lowering the flame retardancy of the flame- retarding unsaturated polyester resin solution and to produce, in good workability, a flame-retarding laminated sheet with good surface smoothness.

Filed: 1985-02-22
Abstract: PURPOSE:To facilitate the adjusting operation of an encoder and to reduce its cost by fitting the Z-phase generation part of a body to be detected on the same straight line with some base point at the output side of a rotating shaft. CONSTITUTION:A device consists of an encoder main-body part 1 and the rotating shaft 2. The rotating shaft 2 has a key groove 2A worked at its output side and a plane cut part 2B is worked on the same straight line with the center line of the key groove 2A at the opposite side of the output shaft side.
