Title: Method for folding fireproof coating material
Inventor: TAKAGI YOSHIHIRO
IPC: B32B15/08
Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To prevent a fireproof expansion sheet from protruding from a metal material and a damage of the sheet die to friction with a forming roll by pressing the sheet from a side to become an inside and providing a recess on the sheet in the case of passing a fireproof coating material between forming rolls for folding the sheet. SOLUTION: The fireproof coating material obtained by laminating a metal plate on a fireproof expansion sheet made of a resin composition containing a thermoplastic resin such as a polyolefin resin, polypentene resin, polystyrene resin or the like, a rubber substance, phosphorus compound and an inorganic filler is passed between forming rolls, and folded in a predetermined shape. At this time, in the case of folding the fireproof coating material, the sheet is pressed from a side to become an inside to provide a recess on the sheet. Thus, the fireproof expansion sheet does not protrude from the metal plate, and is not damaged by a friction with the roll, and hence the material can be folded with good productivity.

Title: Burying work of supporting line anchor
Inventor: IJICHI MITSUTAKE
IPC: E02D5/80
Filed: 1982-08-23
Abstract: PURPOSE:To eliminate the need for external supporting mechanism while making an anchor device compact by a method in which an oil-pressure power is used and the pressing and developing reaction of anchor is absorbed by the anchor itself. CONSTITUTION:Under a condition that the cylinder rod 12 of an oil-pressure cylinder tool is fully expanded, a pipe 11 is fitted on the upper end of a supporting lever 1, and the supporting lever receiver 18 of an oil-pressure cylinder 13 is screwed with the threaded portion (not illustrated) of the supporting lever 1 for connection. These thus connected are penetrated and set in an excavated hole 20 by using the crane boom 21 of a pillar erector car. The oil- pressure pipes 22 and 23 of oil-pressure generating units are connected with the oil-pressure couplers 14 and 15 of the oil-pressure cylinder 13. Afterwards, when an oil pressure is applied in the direction of arrow, the connection between the supporting lever receiver 18 and the supporting lever 1 serves as a force point, and a resistance plate 3 is pressed from above by a pressing and developing force to cause the pipe 11 to be directed downwards. The resistance plate 13 is then opened bilaterally under the guidance of the inductive slope (not illustrated) of a base plate 2 and buried under the ground. Since the pressing of developing reaction of the anchor is absorbed by the connecting point between the oil-pressure cylinder 13 and the supporting lever 1, the need for external supporting mechanism for the pressing and developing reaction can be eliminated.

Abstract: PURPOSE:To reduce a spot shape of an electron beam, so as to improve resolution by making the width of a lead for supplying a deflecting voltage to a deflecting electrode, different according to the cross-sectional shape of the electron beam in a circumferential direction, and by correcting the cross section of the electron beam proceeding in a deflecting region, into a circular form. CONSTITUTION:The size of electric fields formed by leads Hl+, Hl-, Vl+, Vl-, is varied by varying the widths dH, dV of the leads for applying deflecting voltage to deflecting electrodes H+, H-, V+, V- in a circumferential direction of a glass tube. For this reason, the effect to the passing electron beam varies according to the deflecting voltage applied to the leads Hl+, Hl-, Vl+, Vl-, in a circumference on which the leads Hl+, Hl-, Vl+, Vl- of different widths are situated, and the cross sectional shape of the electron beam is thus varied. The cross section of the electron beam proceeding into a deflecting region is corrected into a circular form, by making the widths dH, dV of the lead different on a circumference according to the cross sectional shape of the electron beam. The spot diameter of the electron beam can be reduced, and resolution can be improved.

Abstract: PURPOSE:To prevent the connection of fractured sections of a resin of the same thickness as that of a frame material between leads after the unnecessary resin is punched, by a method wherein the part of side surface between IC leads at the high-bar section of a metal mold is provided with a projection. CONSTITUTION:The dam 3a surrounded by leads 1 and a tight-bar 2 is provided with a projection 6 of rectangular piece form. Sealing by pressing a resin 5 fit in this metal mold generates an unnecessary bur of resin 31. When this unnecessary bur of resin 31 and the projection 6 are removed by being punched out, fractured sections 8 formed between the inside-surface leads of a resin- sealed IC come not to be joined between the leads 1. Therefore, Ag migration does not generate in the Ag-plated leads 1, resulting in resin sealing of high reliability. It is practically advantageous to provide the piece projection 6 in a form of rectangular prism to the degree of no connection of fractured sections 8 between the leads.
