IPC: F02F5/00
Filed: 1979-06-14
Abstract: PURPOSE: To manufacture a pinston ring having excellent air-tightness with a cylinder liner by producing pressed powder by using a true circular form of a mold in the manufacturing process with a sizing process for a sintered alloy piston ring.  
     CONSTITUTION: An atomized iron powder is mixed with a lubricant and then molded by compression in a real circle form of a mold to manufacture a piston ring element material whose dimension (outside diameter D 1 ) is D+(A-C)/π, where D is the nominal diameter of piston ring, C is the matching mouth aperture of piston ring, and A is the width dimension of matching mouth cut in the subsequent process). The element material is sintered and cut off to the width A to provide a matching mouth. Then, the material is put in a real cycle form of a sizing die for sizing so that the matching mouth size is 0W0.2mm, the upper and lower sides are pressed to close the matching mouth, and the peripheral surface closely contacts with the inside circumference of the die. Lastly, a jig having the same outside shape and dimension as the inside circumferential shape and dimension of the piston ring in a free state is fitted into it and a heat treatment is applied. Then, the jig is removed.

Title: Pure ice making system
Inventor: SATO NAOYUKI
IPC: F25C5/04
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To make a pure ice of specified shape continuously and automatically. SOLUTION: An air spray tube 12 is disposed in a drain water tank 11 and the air is supplied to the air spray tube 12 from an air pump 13. Consequently, fine bubbles are scattered from the air spray tube 12 into the drain water. Upon reaching the surface of drain water, the bubble 14 bursts to scatter water droplets into the air. The scattered water droplets adhere to the surface of a rotary roll drum 15 and when the surface thereof is cooled down to 0 deg.C or below, the water droplets are frozen to produce a seed ice. The seed ice is grown as a crystal of pure ice 19 based on the water in the drain water on the surface of the drum, 15 cooled down to 0 deg.C or below. Fine bubbles 14 are further blown to the surface of the pure water 19 in order to remove impurities and mixtures from the vicinity of the surface of pure ice 19 and they are excluded from the ice.  The pure ice 19 grows into a mass of ice 23, impurities and mixtures are cleaned off from the surface thereof, before the pure ice 19 is sorted on a separation slope to have a specified size and collected.

Filed: 1989-03-27
Abstract: PURPOSE:To recognize a dot character in the same way as the normal character by calculating a run length, and interpolating a picture interrupted part, which is generated in histograms prepared in the X and Y directions and is the characteristic to the dot character, as the continuous picture. CONSTITUTION:Histograms of black picture elements in the X and Y directions are respectively obtained from picture data stored into a picture memory 4 for areas corresponding to character recognition, after the data of the histograms are once stored to a storing means 6, the run lengths are obtained for the respective histogram data X and Y. Further the run length data are scanned in the X and Y directions, and the run length data of the picture elements, which are smaller than the dot intervals of the dot characters set beforehand and indicate the non-existence of the picture, are corrected to the run length data where the picture is continuous. Thus the dot character included in the recognition objective area can be segmented, and the dot character can be recognized.

Title: Light receiver
Inventor: HAINRITSUHI YURUGENSEN
IPC: H04N1/46
Filed: 1982-05-06
Abstract: A light pick-up device for transparency and/or opaque scanning in either a drum or flat bed scanning device consists of a hollow body, which exhibits a light entry opening for the modulated light coming from the master. The inside surface of the hollow body, which is designed as a light pick-up surface for the opto-electronic conversion of the scanning light into an image signal, consists of a multitude of sub-surfaces, whose surface normals are oriented in the direction of the incoming scanning light. The sub-surfaces are the light surfaces of either opto-electronic transducers or are the end faces of optical fibers whose other end faces are coupled to an opto-electronic transducer. Because the disruptive influence of scratches and shadow edges in the master is suppressed, a high efficiency and a good uniformity of the scanning are achieved with the light pick-up device.

Abstract: PURPOSE:To form well-shaped edge drops at both ends of rolling steel sheets arranged in two lines by measuring the distance between the two sheets and setting it to a target distance in parallelly rolling two lines of steel sheets at the same time by the same cold tandem mill. CONSTITUTION:Two rolls of steel sheets 1 are unwound from two pay-off reels 11 and are parallelly rolled by a cold tandem mill 12. In this case, the distance between both sheets 1 is measured by a measuring instrment 14 provided to each rolling stand to input its measured value to a comparison arithmetic device 15. The device 15 compares the inputted value with a set value of target intersheet distance, and a shape controlling means of each stand is actuated each by an outputted value obtained by said comparison to make the distance between the sheets coincide with the set value. The shapes of edge drops at both ends of rolled sheet 1 are adjusted to make the plated surfaces at both ends flat when the sheet surface is subjected to galvanizing treatment.
