Title: Thinning-out unit
Inventor: TSUKUMO ATSUSHI
IPC: G06V30/10
Filed: 1979-07-23
Abstract: PURPOSE:To thin out a binary pattern without distortion even at the intersection of a character part by forming an internal pattern at each point of an original pattern from upper and lower, and right and lower areas and areas at respective points and then by forming a frame pattern of the original pattern and internal pattern. CONSTITUTION:Input pattern quantization part 1 scans an input pattern in a two- dimensional array shape and binary-codes and outputs shade at each pattern position to thinning-out part 2. Thinning-out part 2 deletes bits, one by one, in one run without losing linkages from the circumference of the pattern and continues to thin out the pattern until the line width of the input pattern reaches one or two bits, thereby transmitting the result to final thinning-out part 3. Control part 5 receives control signal 52 for thinning-out part 2 to exercise operation control over quantization part 1 and thinning-out parts 2 and 3 with control signal 52. Through the thinning-out processing of thinning-out part 2, an internal pattern is formed from circumferential areas of each point of the original pattern and this pattern and original pattern are used to form a frame pattern which can not be deleted, so that bit-by-bit delection processing will be carried out under deletion conditions symmetrical vertically and horizontally and obliquely at angles of 45 deg..

Abstract: PURPOSE:To produce a polymer liquid crystal composite film without limited by properties of a liquid crystal material to be used, and to improve characteristics such as to obtain low driving voltage, high response speed and low hysteresis by preliminarily treating a porous polymer thin film with a chemical modifying agent. CONSTITUTION:A polymer composite film is formed by dispersing fine particles in a polymer material having reactive groups, and then the film is treated with a solvent which dissolves the fine particles but does not dissolve the polymer material so that the fine particles are removed to obtain a porous polymer thin film 1. The surface of the porous polymer thin film 1 is modified by coupling reaction of a chemical modifying agent 3 having groups which can be bonded with the reactive groups so that surface characteristics of the polymer are controlled. Then a liquid crystal material 6 is injected into circular openings in the thin film. The polymer having reactive groups is obtd. by using monomers or oligomers having chemically reactive groups or a mixture of these. As for the chemical modifying agent, any material may be used as far as it can modify the surface of the polymer material.

Filed: 1979-07-25
Abstract: PURPOSE: To cool efficiently gas, by a method wherein a high-temperature pyrolysis gas together with solid particles ascends through a draft tube, and then the gas together with a circulating oil descends through inner tubes.  
     CONSTITUTION: A pyrolysis gas of heavy oil or coal is supplied from an inlet 8. The gas together with solid particles in a fluidized bed 7 is blown up through a draft tube 8'. The solid particles are separated from a process gas at a baffle 9 and slowly descend through upright outer tubes 5. During the blowing up of the solid particles, the temperature of the solid particles rises. During the descending of the particles, the heat of the particles is given to the upright outer tubes 5. The cooled process gas reverses its course at a header 4 for the process gas system, and descends together with a circulating oil through upright inner tubes 6. During descending, the process gas is cooled and gives heat to the surfaces of the upright inner tubes 6. Then the gas is separated from the circulating oil at a header 4' for the process gas system, and introduced into an outlet. The circulating oil is introduced through a header 3' for the circulating oil system into a header 3 for the circulating oil system by means of an oil pump 12. Spaces between the upright inner tubes 6 and the upright outer tubes 5 are cooled by water which is circulated by means of a pump 15.

Abstract: PURPOSE:To make the absorption and relief of reverse load attainable, by letting a pressing member press down the lever of a diaphragm spring used for energizing a clutch plate when the excessive reverse load is imposed on from the driven shaft side, and thereby reducing the energizing force of the diaphragm spring. CONSTITUTION:In a friction clutch 18 available in power transmission device for a motorcycle, etc., usually clutch plates 25... and 26... come close to one another under pressure by a diaphragm spring 31, and rotation of a housing 23 leading to a crankshaft via a driven gear 16 or the like is transmitted to an intermediate shaft 12 via these clutch plates 25... and 26..., a pressing member 38 and a boss 38. Under this condition, when excessive reverse load is imposed on the intermediate shaft 12 due to action of an engine brake, the pressing member 38 goes to the right by action of a torsion spline 40, forcibly pressing down a lever part 34 of the spring 31 with a pressing rod 39. With this pressure, energizing force in the spring 31 is well weakened whereby there produces a slip between these clutch plates 25... and 26..., thus reverse load is absorbed and relieved.
