Title: Binary multi-valued image conversion method
Inventor: SATO YOSHIYUKI
IPC: H04N1/405
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To prevent periodic moires from appearing in a multi-valued image by temporarily generating a dummy binary image, having black pixels dispersed at random from a binary image and converting it into a multi-valued image by using a scan matrix which has a different size from or the same size with a threshold matrix. SOLUTION: A dummy binary image is generated by having coloring materials (or white pixel) of an inputted binary image moved and dispersed, and a multi-valued image which has a different scan matrix size from or the same size with a threshold matrix is obtained from the binary image. This converting method determines a colored image of interest in the binary image in a first step and determines the movement position of the colored image of interest in the binary image in a second step. In a third step, the colored image is dispersed to the above determined movement position and in a next step, the multi-valued image is obtained according to the binary image obtained from the result of the 3rd step.

Title: Production of casting
Inventor: OKAMOTO YOSHIO
IPC: B22C1/22
Filed: 1992-11-06
Abstract: PURPOSE:To greatly improve the efficiency of recovered sand regeneration by executing the powerful removal of the residual chemicals by the interfriction among sand grains and the removal and wash of residual fine powders. CONSTITUTION:This method consists in recovering and regenerating the recovered molding sand after production of castings with artificial molding sand, as represented by ceramic beads, by a dry process. The recovered molding sand is charged by gravity fall by each constant amt. to a revolving rotor revolving at a high speed. The residual chemicals, such as binders and hardeners, sticking to the surfaces of the recovered molding sand grains are peeled by the scrubbing generated by the friction among the sand grains between the fixed side of the rotating outer periphery of the revolving rotor and a stationary ring having a U-shaped section. The peeled chemicals in a dust form are powerfully sucked away by a dust collecting hood. Further, many opening holes are provided at the rear surface of the recovered molding sand and air is ejected therefrom to fluidize, agitate and bubble the sand. As a result, the residual fine powers intruding among the sand grains are exactly removed and washed.
