Title: Hume concrete pipe and manufacturing device thereof for method of propulsion construction
Inventor: MARUYAMA NOBUAKI
IPC: E21D9/06
Filed: 1988-12-15
Abstract: PURPOSE:To contrive the reduction of friction resistance with the natural ground by forming in the periphery of a Hume concrete pipe a lubricant circulating hole communicating with a lubricant injection hole, mounting to a groove wall an angular cylindrical coating member having a communication hole communicating with the lubricant circulating hole and forming the groove wall in a rear side into a rising slope. CONSTITUTION:A Hume concrete pip 1 forms in its periphery an endless lubricant circulating groove 3 mounting in a ring shape along a groove wall a steel- made angular cylindrical coating member 7, coating lubricant injection holes 2a, 2b, providing through holes 8, 9 to be drilled. While the lubricant circulating hole 3 is formed into a recessed groove shape, and its rear side groove mold 4 is formed as a slope rising from a lower end part 5 toward an upper end part 6 in the point end of the Hume concrete pipe 1. And a lubricant, even when it is injected from the single lubricant injection hole 2a, is uniformly distributed to the peripheral surface. Thus, the lubricant can be distributed even to the rear side of the Hume concrete pipe in its propulsion direction.

Title: Wire bonding equipment
Inventor: TSUCHIDA MINORU
IPC: H01L21/607
Filed: 1989-12-06
Abstract: PURPOSE:To prevent the generation of rotation angle deviation between the axial direction of a wire hole and that of a wire, and improve the reliability and the yield of products using the wires, by constituting a wedge in the manner in which the surface shape intersecting perpendicularly to the axial direction is polygonal. CONSTITUTION:The shape of surface S, of a wedge 9, intersecting perpendicularly to the axial direction is polygonal, e.g. triangular. As a result, when the wedge 9 is fixed to a horn 6 with a screw, the rotation angle deviation is not generated between the axial direction of a wire hole 9a and that of a wire 11, so that, at the time of bonding process, the damage of the wire 11 and the generation of whiskers caused by the contact of the side wall of the wire 11 and that of the wire hole 9a can be prevented. Thereby the strength decrease of the wire 11 caused by the damage of the wire 11 and the short circuitting between adjacent wires caused by the whiskers formed on the wire 11 can be prevented. Hence the reliability and the yield of a semiconductor integrated circuit can be improved.

Title: Method for casting metallic strip, strip casting apparatus for casting metallic strip and twin roll strip casting apparatus
Inventor: KAUL HAROLD ROLAND
IPC: B22D11/06
Filed: 1998-11-09
Abstract: PROBLEM TO BE SOLVED: To prevent the thinning of solidified shell at the edge parts of casting roll by changing the heat transferring condition at the interface between the casting roll surface and molten metal along the casting roll and selectively promoting the heat transfer at the edge parts of the casting roll surface. SOLUTION: The cleaning device for the casting roll is formed with one pair of cylindrical barrel shape brushes 31, 32 extended in the longitudinal direction of the casting roll 12 and separated in the peripheral direction thereof. Since the brushes 31, 32 are overlapped, the center part 33 is cleaned with both brushes 31, 32 but the edge parts 34 are cleaned only with one side of the brush. Then, the molten metal is brought into contact with the cooling surface 12a of the casting roll 12 and solidified on the surface of the casting roll 12 and the solidified metal is separated from the surface of the casting roll 12.  Further, the surface of the casting roll 12 is cleaned with the brushes 31, 32, but since the contacting conditions of the brushes at the center part 33 and the edge parts 34 are different, a large quantity of metallic oxide remains at the edge parts 34 and the heat transfer at the surface edge parts of the roll 12 is selectively promoted.

Title: Fiberboard and formation thereof
Inventor: MATSUMOTO SEIJI
IPC: B27M1/00
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To facilitate curving deformation so as to obtain a clean curved surface shape, in a fiberboard formed by laminating a large number of fiber materials on the same surface to integrate them, by setting the laminating direction of the fiber materials to the lateral or longitudinal direction of a fiberboard main body. SOLUTION: In a fiberboard formed by laminating a large number of fiber materials on the same surface to integrate them, the laminating direction of the fiber materials 1 is set to the lateral and longitudinal directions of a fiberboard main body 2. By this constitution, the fiberboard becomes hard to deform in its thickness direction as a whole and becomes easy to stretch and contract in its surface direction. Therefore, even when the fiberboard is processed into a curved surface shape, it can be prevented that the board main body 2 is bent and wrinkled. Further, the fiberboard can be deformed smoothly by the tensile force or compression force acting along the upper and rear surfaces of the fiberboard main body 2 and a smooth curved surface can be formed.

Abstract: PURPOSE:To prevent the deformation of fins from the base parts thereof when substances such as sand grains and the like which are included in heat exchanging fluid are collided against pin-type fins at the fore part of the upstream side of a heat exchanger by a method wherein the sections in the bases of the fins at the fore parts of the upstream side of heat exchanging fluid are increased by forming them longer in the flow direction of the heat exchanging fluid than the sections of the other fins. CONSTITUTION:A plurality of fins 3 are arranged on a tube 1 in a plurality of rows along the flow direction of heat exchanging fluid. The section of pin type fins 3a at the fore part of the upstream side of heat exchanging fluid are formed so as to be rectangular shape and the sectional area of the same is increased than the sectional area of fins 3b at the downstream side of the heat exchanging fluid which are provided with same square or rectangular configuration. The long sides of the sections of the fins 3a at the fore part of the upstream side are positioned in the flow direction of the heat exchanging fluid substantially and are longer than the long sides of the downstream side fins 3b while the short sides of the sections are provided with the same length as the length of the short sides of the downstream side fins 3b substantially. According to this method, the fins 3a will never be deformed since the strength thereof is sufficiently high when substances such as sand grains and the like which are included in the heat exchanging fluid during the running of vehicles are collided against them whereby gaps between fins will never be clogged by the substances such as the sand grains and the like.

IPC: G01N21/90
Filed: 1987-12-14
Abstract: PURPOSE:To inspect foreign matter with high accuracy, by transferring an ampule in a state inclined by a predetermined angle while rotating the same and applying vibration during transfer. CONSTITUTION:Each of ampules 1 is transferred in a process fed by a roller chain 10 while rotated along the core thereof by the rotation of a roller 3 and a plurality of the ampules are simultaneously observed by an industrial camera arranged above to inspect the appearance and whole shape of each ampule. At this time, each of the ampules 1 is held by a chuck 4 so as to be inclined, for example, by 2-6 deg. with respect to a horizontal direction. Thereafter, when the ampule 1 is fed in an inclined state, a vibrator 6 gives high frequency vibration to the body part of each ampule. By this method, each ampule 1 is rotationally moved while receives vibration in a vertical direction. Therefore, the foreign matter having specific gravity larger than that of a powder F mixed in the powder F can be detected because of easily flying out to the head part.
