Title: Method and apparatus for scarfing of stainless steel
Inventor: HIROSHIMA TATSUO
IPC: B23K7/08
Filed: 1978-11-28
Abstract: PURPOSE: To make possible the scarfing of stainless steel which is considered difficult by improving the fluidity of slag through the use of flux and disintegrating Cr-oxides being formed with scale and the like in performing scarfing of stainless steel.  
     CONSTITUTION: An iron oxide particle injection nozzle 7 such as of scale is provided in front of the scarfing fire-nozzle 4 of the scarfing nozzle 3 of a scarfing device 2 and a flux injection nozzle 5 is provided near the scarfing fire port 4. At the time of scarfing stainless steel material 1, flux is sprayed to the scarfed surface from the nozzle 5 by a flux injector 6 to prevent flying of the powder being emitted from the scarfing fire port 4 by the oxygen flow being emitted from the fire port 4 and improve the fluidity of the slag by the flux. Scale, etc. are blown at a high speed to the surface of the scarfing molten pool from the scale injection nozzle 7, by which the Cr oxides produced during scarfing are disintegrated and since covering of the scarfed surface by these does not occur, the scarfed surface is fusion-cut smoothly.

Title: Image attribute discrimination method and image attribute discrimination circuit
Inventor: HIRATSUKA SEIICHIRO
IPC: G06T9/20
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To discriminate an image attribute with high accuracy by a simple method by extracting the contour of an image input signal to generate an image contour signal thereby discriminating the image attribute based on the image contour indicated by the signal. SOLUTION: A contour extract means 7 extracts the contour of an image from an image input signal vi and outputs an image contour signal vc. An image attribute discrimination means 8 discriminates the image attribute of a character, a photograph and a dot image from the image contour signal vc and outputs an image attribute discrimination signal vd. An image attribute discrimination table 10 receives the image contour vc from the contour extract means 7 and outputs the image attribute discrimination signal vd denoting an image discrimination result based on pattern matching by a predetermined contour pattern. The image discrimination result is obtained by conducting statistic processing of the contour pattern of a character, a photograph and a dot image in advance and setting a contour pattern based on frequency of occurrence.  The image attribute is discriminated with high precision through the statistic processing of the contour pattern.

Title: Structure for holding ball gathering frame plate for pin ball machine
Inventor: RI SEIMOU
IPC: A63F7/02
Filed: 1988-06-15
Abstract: PURPOSE:To obtain on a mechanism plate a ball gathering frame plate holding construction needing no special working by providing an engaging member engaging an engaging portion inside partition walls constituting both side walls of a ball gathering frame, while locating the engaging member lower than the rear face of the ball gathering frame plate. CONSTITUTION:A ball gathering frame plate 5 is constructed to be held by a pivotable lock tube 13 as an engaging member located inside the ball gathering frame plate 5, so that, when a mechanism plate provided on the rear surface of a pin ball machine to be opened and closed is closed, nothing abuts against the peripheral portion of the mechanism plate and thereby the mechanism plate can be smoothly surely closed to the pin ball machine. Also, no hinge, engaging fittings, etc. exist on both sides of partition walls 7 of the ball gathering frame plate 5, the lateral length of said plate 5 can be elongated. Thus, the rear surface of a play plate 3 can be covered over a wide extent. Further, since the upper end of the pivotable lock tube 13 is formed below the rear surface of said plate 5, said upper end does not abut against the inner surface of the mechanism plate. Hence, the mechanism plate can be smoothly and surely closed to the pin ball machine.

Filed: 1983-08-16
Abstract: PURPOSE:To prepare efficiently formed articles of chitosan being excellent in the strength and elasticity modulus without using an intricate solidifying medium, by extruding an aqueous chitosan solution concentrated high than a specified value, under pressure. CONSTITUTION:An aqueous solution of high concentration, which is prepared by dissolving chitosan of 10wt% or more in a dilute-acid water solution of acetic acid, hydrochloric acid, sulfamine acid or the like, is extruded to be formed under pressure through a spinning nozzle or any other forming nozzle. The forming pressure applied on the occasion is about 10-500kg/cm<2>. By extruding the aqueous chitosan solution of high concentration under said pressure, chitosan molecules are orientated in a high degree in the extrusion, and as the result, formed articles having remarkable strength, such as threads, for instance, are formed without using any solidifying medium and even just after the forming. In addition, the strength and the elasticity modulus of the extruded threads can be improved sharply by stretching the threads to be about 2-10 times longer just after the extrusion or thereafter.
