Title: Producing device of metal powder
Inventor: SHIMADA WATARU
IPC: B22F1/00
Filed: 1979-03-19
Abstract: PURPOSE: To produce the metal powder of high quality at high performance by connecting a powder-capturing chamber having an atmosphere regulating mechanism to a plasma jet generator.  
     CONSTITUTION: Voltage is applied between the non-consumable electrode 6 and water-cooled copper nozzle 7 of a plasma generator and inert gas such as Ar is flowed to let a plasma jet 8 of extra high temperature and high speed be generated. A metal wire material 9 of the same composition as those of the intended powder is supplied into this plasma jet 8. The metal wire materil 9 is instantaneously melted by the plasma jet 8 and becomes fine molten metal which then flies in a powder- capturing chamber 11 connected to the device. Inert gas such as Ar is being flowed through the suction hole 12 on the side in proximity to the plasma jet generator of the chamber 11 and is being exhausted through the exhaust hole 13 on the other end side, thus the inside of the chamber 11 is controlled to the inert atmosphere. Hence, the fine molten metal powder having flown freezes without being contaminated by oxygen, etc. and falls onto the floor surface of the chamber 11.

Title: Compression dehydrating device for sludge
Inventor: SHIMIZU HIDEAKI
IPC: B30B9/10
Filed: 1983-03-02
Abstract: PURPOSE:To compress and dehydrate sludge to about 50% moisture content at which the sludge is self-burnable by pressing the sludge grains contg. 70-80% moisture content by a compressing rod which is actuated by a pressing cylinder while enclosing the sludge grains with a compressing frame on a pressure resistant filter cloth on a holding plate. CONSTITUTION:The sludge which is preliminarily dehydrated to 70-80% moisture content is refined to sludge grains having about 10mm. diameter and said grains are charged by a conveyor 19 into a charging frame 15 on an endless belt-like pressure resistant filter cloth 14. The flame 15 is moved upward by a liquid pressure lifter 16 and while the piled sludge grains are deviated from the frame 15, the cloth 14 is moved to transfer the sludge grains on a holding plate 10 having many holes. A compressing frame 9 is then lowered to enclose the piled sludge grains on the cloth 14 and a liquid pressure press 1 is driven to lower the compressing rod 7 at the top end of a pressing cylinder 5, so that the sludge grains in the compressing frame are pressed. The sludge grains are pressed and the water contained therein is passed through the holes of the cloth 14 and the plate 10 and is run downward through the discharging holes of a pressure receiving base 11 into a wate collecting tray 13. The sludge is thus easily dehydrated to about 50% at which the sludge is self-burnable.

Title: Character pitch detector
Inventor: TSUJI YOSHITAKE
IPC: G06K9/34
Filed: 1983-03-01
Abstract: PURPOSE:To measure a character pitch accurately even if the character pitch is not estimated in advance by estimating the character pitch on the basis of an integrating value of a character number, character lump width and space width of the character lump width in a character group. CONSTITUTION:A comparison section 22 checks that the character lump width stored in a register 20 transferred sequentially from a controller 7 belongs to an effective section stored in a register 10, and when the width belongs to the section, a character lump detecting signal 101 is brought to logical 1. The controller 7 transfers the space width stored in a register 21 to a comparison section 25. The comparison section 25 compares the content of a permission register 24 with the space width and when the space width is smaller than the content, the section 25 sets a section detecting signal 102 to logical 1. Thus, the space width and the character lump width in a register 23 are fed to an adder section 26. The adder section 26 adds the character lump width, the space width and the content of an integrating value register 27 and stores the result to the register 27. When a character lump belonging to the effective section is detected, a continuous number counter 28 is counted up by 1 by the device 27. The operation above is repeated until the signal 102 reaches 0.

Inventor: SAKOMA YASUHIRO
IPC: B22D7/00
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To obtain an ingot having good surface after ingot-making in a bottom-pouring ingot-making of molten steel. SOLUTION: In the ingot-making method of the molten steel, with which the bottom part of a molten steel pouring tube 1 and the bottom part of bottom-pouring molds 2A, 2B, 2C are communicated through a runner 2R and the molten steel stream 7 flowing down from the bottom part of a ladle 6 is poured from the upper part of the molten steel pouring tube 1 and flows in from the bottom parts of the bottom-pouring molds 2A, 2B, 2C through the runner 2R to make the ingot in the bottom-pouring molds 2A, 2B, 2C, the stream of the molten steel 7M in the inner part of the molten steel pouring tube is made to low speed by forming the inner diameter of the molten steel pouring tube 1 to the large diameter so as to reduce the variation of the molten steel surface caused by gas boiling in the bottom- pouring molds 2A, 2B, 2C and thus,  the float-up of the gas G contained in the molten steel 7M is promoted and the gas quantity flowing in the bottom-pouring molds 2A, 2B, 2C is reduced. Alternatively, a sealing body surrounding the molten steel stream 7 between the bottom part of the ladle 6 and the upper part of the molten steel pouring tube 1 is arranged to prevent the development of the gas caused by the entrapment of atmosphere and the atmosphere oxidizing reaction of the components in the molten steel and thus, the gas quantity flowing in the bottom-pouring molds 2A, 2B, 2C is reduced.

Title: Belt conveying device
Inventor: MATSUZAKI TSUTOMU
IPC: G03G15/00
Filed: 1995-02-22
Abstract: PURPOSE: To prevent meandering of a belt and damage of a belt end part by means of constitution consisting of less parts by elastically moving a frame, which supports at least one roller, in the axial direction toward a belt guide member. CONSTITUTION: Ordinarily, an intermediate transfer belt 10 is operated by bringing end faces into contact with either of edge guides 20a, 20b and keeping a meandering prevention roller 14a in a balance position based on both of plate springs 19a, 19b. When the belt 10 meanders, one side end face is brought into contact with the inside face of the edge guide 20a on one side intensively, and if this contact force exceeds restricting force of the supporting plate springs 19a, 19b for the meandering prevention roller 14a, the meandering prevention roller 14a is moved in the opposite direction to the meandering direction of the belt 10 by means of deflecting deformation of the plate springs 19a, 19b.  In this way, contact force of the belt 10 to the edge guide 20a is lowered by an equivalent of a shift of the meandering prevention roller 14a, and as a result, buckling or damage in a meandering side end part in the belt 10 is prevented. In this process, an end part inside face of the belt 10 is guided by means of a guide member 22.

IPC: G02B6/26
Filed: 1988-02-18
Abstract: PURPOSE:To reduce the number of parts to miniaturize an optical circuit element by forming a part having a rounded end in the front end of a constant polarizing fiber and sticking a prescribed light absorbing material to a constricted part to give a lens function and a polarizing function. CONSTITUTION:A part 12 having a rounded end is formed in the front end of a constant polarizing fiber 11, and a constricted part 14 which is constricted in the same direction as the polarization direction is formed near the part 12 having the rounded end. A light absorbing material 15 is stuck to the surface of the constricted part 14 in the same direction as the polarization direction. Consequently, said part 12 has a lens function and the light absorbing material 15 stuck to the constricted part 14 has the same polarizing function as a polarizer. Thus, since it is unnecessary to individually provide a lens and a polarizer, the number of parts is reduced to minimize the optical circuit element.
