Title: Manufacture of double-bend pipe
Inventor: OBARA YAMAHISA
IPC: F16L39/00
Filed: 1981-05-14
Abstract: PURPOSE:To easily manufacture a double-bend pipe by passing and inner pipe through an outer pipe, and by inserting the inner pipe into the outer pipe having straightly cylindrical parts respectively at both the ends of a 90 deg. bent cylindrical part, and pressing the outer pipe from both sides to deform the pipe into ''Koban''(an old Japanese coin having an elliptical shape)  shape against the elasticity fo the pipe. CONSTITUTION:Stays 3 are fixed to the positions near to cylindrically bent part (b) of the outer circumference of a straightly cylindrical part 2 at the side of large-sized end part, at equal intervals in the circumferential direction, before passng an inner pipe through an outer pipe. At this time, a bend of a lower bent part 3(b), perpendicularly connecting a lower step piece 5 of the stay 3 and the bottom end of a stay piece 3', is bent reversely and strecthed to make the stay 3 lie down around the part 2. Next, a small-sized straightly cylindrical part 2' of the inner pipe is inserted into a large-sized straight part 1 of the outer pipe to press the part 1 from both sides and deform it into an elliptic shape or ''Koban'' shape against its elasticity in  order to force the inner pipe into the outer pipe and to pass it through the latter by expanding the width W of the inner surface at the inside of 90 deg. bent outer pipe and the inner surface  at the outside of the part 1. Next, the upper step piece 4 is fixed to the inner circumference of  the part 1 after raising up the laying piece 3' to back it into an original form.

Abstract: PROBLEM TO BE SOLVED: To improve shape retentivity by using thrown silk, in which hemp fibers are intertwisted in specific size, as warp, supporting warp between the upper and lower intersecting points of weft, in which two thrown silk are intertwisted mutually, and forming a net with specific mesh width. SOLUTION: The single fibers of a hemp are intertwined, and thrown silk 2 having size of 10-36 yarn numbers is formed. Thrown silk 2 is passed in a tank, in which one kind or a plurality of kinds of a water repellent, a mildewproofing agent, adhesives, an antibacterial agent, a preservative or the like are mixed and housed, and dried and anticorrosive treatment is executed. One thrown silk 2 is used as warp, two thrown silk 2 are employed as weft, thrown silk is intertwisted at least once at every one stage of weft, and a crossing section 3 is formed. Thrown silk is knitted while warp is inserted into the crossed space 4 of the crossing section 3, and a netted vegetation base material 1 having mesh width of an approximately 10×5mm square is formed.  Accordingly, since mesh breaking is difficult to be generated and meshes can be ensured, the outflow of soil can be prevented for a prolonged term.

IPC: G01N15/02
Filed: 1992-03-27
Abstract: PURPOSE:To provide the accurate size information of an extremely fine flaw or grain by providing the process integrating the intensity of the scattered light of the grain or flaw. CONSTITUTION:A laser beam LB emitted from a light source 1 is converted into the parallel light flux by a cylindrical lens 2, it is then squeezed by a spherical lens 3, and a sample 4 is illuminated with the linear light flux or the converged light flux. Scattering is generated by a grain or a flaw in the sample 4 via this incidence, the scattered light in the direction crossing the optical path of the light flux fed to the sample 4 is received by an image pickup element 5 via an optical system 9, and it is processed by an image processor 6 to obtain a grain image. Image processing is performed by a CPU 7 based on this image information, and the integration calculation of the scatter intensity on the individual grain is performed. The scatter intensity is proportional to the sixth power of the diameter of the grain, and the size information of the individual grain can be obtained based on the integrated intensity of the scattered light.

When the skier reduces his weight load and the board is loosened toward a counter curved direction, a transmission device 13 imposes a large braking upon the ski board, and restricts the loosening actuation of the board. That is, the supporting member 17 is particularly pushed back to the inside of the shoes 1 through the spacer 19, the skier's foot is extremely pressed until the spacer 17 is contacted to the sole of the shoes for stepping.  Thus, the transmission device 13 can control the movement of the counter curved direction of the ski board.

Title: Method for coupling ceramics member and metallic member
Inventor: IGARI TOSHIHIDE
IPC: B23K1/19
Filed: 1990-03-22
Abstract: PURPOSE:To improve coupling strength by inserting a round bar-shaped ceramics member having an annular groove into a hollow cylindrical metallic member and repeating cooling and heating from the outside to cause the plastic deformation of the metallic member, and thereby coupling this member to the ceramics member. CONSTITUTION:The bar-shaped ceramics member 2 made of Si3N4, etc., provided with the shallow annular groove is inserted into one end of the hollow cylindrical metallic member 1 consisting of a stainless steel, etc. A part (a) of the metallic member 1 is then subjected to the repetition of the cooling and the heating by cooling water nozzles 3 and a high-frequency heating coil 5 and is successively moved in a low-temp. region 6 and a high-temp. region 7 along the axial direction. The plastic deformation of shrinkage is generated in the ceramics enclosing part 1a of the metallic member 1. This part tightens the ceramics member 2 when the part restores to room temp. In addition, the part 1c of the metallic member 1 on the outer side of the annular groove 8 of the ceramics member 2 is intruded into the annular groove 8 by the plastic deformation of the shrinkage. The ceramics member 2 and the metallic member 1 are thus more securely coupled. The pull-out of the two members hardly arises.
