Title: Flange connecting structure
Inventor: TSUJI TOSHIAKI
IPC: F16B41/00
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To prevent connection of flanges from being released or loosened, by covering a head part of a bolt or a nut with a cap, in a flange connecting structure for connecting flanges to each other by using a bolt and a nut. SOLUTION: A first nut 7 is tightened from above, and a second nut 8 is tightened from above it. At this time, the second nut 8 presses the first nut 7 from behind to lock the first nut 7. A cap 9 is put on the second nut 8 from above and bent inward at a cut 11 so that the end 9a may be beyond a stepped part 8a of the second nut, and the cup 9 is fixed to the second nut 8. Therefore, the second nut 8 is covered with the cap 9, and the second nut 8 can not be removed by being directly turned from the outside.

Title: Production of electroconductive crosslinked molded article
Inventor: KAWAHIGASHI MASAKI
IPC: C08J3/24
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an electroconductive, highly crosslinked molded article with a reduced moisture content. SOLUTION: This method for producing an electroconductive crosslinked molded article comprises extruding an electroconductive composition comprising a polyolefin-based resin, an unsaturated silane compound, carbon black and an organic peroxide at 100-150 deg.C, followed by heating at 160-240 deg.C. The simultaneous utilization of two kinds of crosslinking systems, i.e., a silane crosslinking and an organic peroxide crosslinking can lower the moisture content of the molded article and increase the degree of crosslinking, because the water formed by a side reaction of the decomposition residues of the organic peroxide is consumed by the silane crosslinking.  The electroconductive composition is prepared by blending 0.5-3.0 pts.wt. of the unsaturated silane compound, 10-80 pts.wt. or the carbon black and 1.0-3.0 pts.wt. of the organic peroxide with 100 pts.wt. of the polyolefin-based resin.

Abstract: PROBLEM TO BE SOLVED: To reduce a space necessary for an article moving device and to easily control the same by vertically moving an article holding device by an elevator device, and rotating the article holding device by a rotating device while keeping its rotary shaft in the vertical direction. SOLUTION: An article holding hand 25 is formed by a linear motor 22 for controlling the horizontal movement in the X direction and the Y direction, an elevating cylinder for controlling the elevation in the Z direction, and a rotary motor 24 for controlling the rotation in the θ direction while keeping the rotary shaft in the vertical direction. Whereby the bottles 1 can be horizontally moved and controlled in the X direction and the Y direction, and vertically in the Z direction, and further rotated and controlled in the θdirection while keeping the rotary shaft in the vertical direction. A moving range of the article holding hand 25 is limited within a range defined by a fixed outline of a platen 21, and the large space is not needed around a handling device.  Further the computing and the control can be easily performed by using a camera 16 and the handling device when the bottles 1 are aligned.

Title: Production of cylindrical body
Inventor: SUMITANI MITSUTAKE
IPC: B29L23/00
Filed: 1991-12-09
Abstract: PURPOSE:To enhance a dimensional accuracy, reduce a variation in inner diameter, simplify a mold in construction, and lower a production cost by a method wherein after a parison having a through hole in an axial direction is molded by an injection molding means, an intermediate peripheral wall part of the parison is expanded by blow molding. CONSTITUTION:A parison 3 molded by an injection molding means is taken out of the injection molding machine, thereafter being loaded in another blow molding machine 5 and heated. Air is supplied inside a hole 4, thereby expanding an inner wall 6 of a center part of the parison 3 by the amount of a cavity 7 of a blow mold. In this manner, a cylindrical body 8 is obtained. Since injection molding is carried out and, thereafter, blow molding is conducted by another blow molding machine 5, the obtained cylindrical body 8 has a high dimensional accuracy at both end parts 8a, 8b. Furthermore, a dimensional difference in inner diameter with location is reduced in the obtained cylindrical body 8. Since various kinds of cylindrical bodies depending on a blow molding machine can be obtained from one kind of parison, this method can be applied to a multi-kind production.
