IPC: H04N1/403
Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To generate halftone image in which production of an unpleasant pattern is suppressed in the error diffusion method by dividing the halftone image into plural areas and applying binarization processing sequentially to picture elements adjacent to each other in each area. SOLUTION: A pointer denoting a position of a noticed picture element is set to a picture element 0, 0 at an upper left end. In the case of shifting the pointer in the Y direction, a Y increasing direction is set as a direction to be selected and a weighting coefficient matrix is set. Then the image indicated by the pointer, that is, the noticed picture element is finarized. Then the decided binarization output Ox, y is stored in an output image storage device. Then a binarization error attending the binarization is calculated. The binarization error is a correction density 1'x, y subtracted by the binarization output Ox, y. Then the error diffusion to distribute the binarization error to peripheral picture elements is executed.

Title: Manufacture of biaxially oriented polyolefin resin pipe and biaxially oriented high density polyethylene pipe
Inventor: SUGAYA TAKEHISA
IPC: B29C48/32
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To make the high plasticity and the deformability compatible with the peripheral high elasticity and also upgrade the resistance to earthquake by making the degree of orientation of a resin pipe in the peripheral direction higher than that of the resin pipe in the axial direction. SOLUTION: A polyolefin resin is malt-kneaded in an extruder, then is molded in the form of pipe through a mold and the extruded pipe-shaped polyolefin resin is cooled in a water tank or the like while being stretched by a take-up machine, to be cut to the specified length using a cutter. Thus, a billet (a pipe blank) 2 is formed and the pipe blank 2 is made to move forward over the surface of a cone-shaped mandrel 13 whose diameter is enlarged gradually. After this procedure, the pipe blank 2 is forced into the mandrel 13 from behind, while the former is made to closely come into contact with the mandrel 13 by a hydraulic extruder 11. The forcing operation expands the inside dia. of the pipe blank 2 to be oriented in the peripheral and the axial direction simultaneously.  Thus the biaxially oriented polyolefin resin pipe is obtained which has polyolefin particles oriented in two directions, i.e., both axial and peripheral. Consequently, it is possible to make the high deformation follow-up properties to an external stress compatible with the high peripheral elasticity and upgrade the resistance to earthquake.
