Title: Pressure crystallization apparatus and method
Inventor: MATSUDA YUICHI
IPC: B01D9/02
Filed: 1991-01-22
Abstract: PURPOSE:To obtain excellent productivity without generating a problem such as high pressure valve damage by providing a cooling mechanism to a first high pressure container equipped with a pressure mechanism. CONSTITUTION:A raw material is supplied to a first high pressure container 17 and cooled under pressure in the container to crystallize a specific component to form a mixture of a solid-liquid coexisting state and this mixture is passed through cooled high pressure piping 13 to be supplied to a second high pressure container 15 and subjected to solid-liquid separation to discharge a liquid phase component through a filter mechanism (f). Since crystallization becomes easy to generate under cooling and pressure, the pressure in the first high pressure container 17 may be lowered as compared with a case not performing cooling. Therefore, the capacity of the first high pressure container 17 can be increased as compared with that of the second high pressure container 15 and a large amount of the mixture can be subjected to solid-liquid separation. Therefore, a problem such as high pressure valve damage is not generated and excellent productivity (the production of a product per unit time) is obtained.

Abstract: PROBLEM TO BE SOLVED: To conceal an adhesive with an opaque function layer and to make the adhesive invisible from the transparent part of substrate by forming the adhesive within the range from the outer peripheral edge to the inner peripheral edge of the function layer and sticking a pair of the substrates to each other. SOLUTION: Groove parts 6a1 , 6b1 are formed in the outer peripheral part and inner peripheral part of the first substrate 2 and groove parts 6a2 , 6b2 in the outer peripheral part and inner peripheral part of the second substrate 3 to a toric shape.

Title: Reduction method for dither picture
Inventor: HIRATSUKA SEIICHIRO
IPC: G06T3/40
Filed: 1986-01-15
Abstract: PURPOSE:To obtain a picture approximating to a reduce halftone picture generated from an original halftone picture by selecting an optimum scanning aperture among plural types of scan apertures at every picture element through the prescribed arithme tic and taking the counted value of its own picture elements in the aperture for an estimated reduction halftone picture value. CONSTITUTION:The selection order of scanning apertures are set to D C B A, in that order. The aperture D is overlapped with a dither picture. Then, if the aperture is binary-coded by a threshold matrix with its own picture element number seven in the aperture as an average picture element level, as a symbol (y) shows, the dither picture (w) and the binary picture (z) are not of the same pattern, and therefore the aperture D is inappropriate. If the aperture C is overlapped and binary-coded with eight obtained by multiplying its own picture element number four in the aperture as an average picture element level, the aperture C is also inappropriate. If the aperture B is overlapped and binary-coded with four obtained by multiplying its own self picture number two in the aperture by a gain two as an average picture element level, the dither picture (w) and the binary picture (z) are of the same pattern, and therefore the aperture B is appropriate. Namely the picture estimated value comes to four, and the picture element level becomes the estimated value of the reduced halftone picture, as a symbol (x) shows.

Abstract: PURPOSE:To prevent the formation of built-up tooth top even in the case of a ferrous metal body, which were formed usually, and make possible to loosen the conditions of using a gear pump or motor by forming required out grooves inside a body bore. CONSTITUTION:On the inner face of a body bore 2 in a and b ranges where the tooth tops of gears 3 and 4 are pressed against the inner face of the body bore 2, many cut grooves 7 are formed in the axial direction as shown in the figure. During running-in, built-up tooth tops were usually formed on the tooth tops of the gears 3 and 4 and tears or scratches were made on the surface cut by them, but if only the cut grooves 7 are formed, shocks are given to those tooth ends when they  collide with the edges of the cut grooves while the gears 3 and 4 rotate and chips  are not allowed to stick to the tooth ends: therefore, built-up tooth tops are not  formed on the tooth tops during running-in even when a ferrous metal body is used  and a radial clearance on the inner face of the body bore 2 can be made minimum.
