    摘要: A method of production of a cladding tube for a nuclear fuel element wherein a first hollow billet of a zirconium alloy and a second hollow billet of zirconium having a smaller outer diameter than the first hollow billet are formed by heat treatment, forging and cutting. A resilient member is inserted in a space defined between the first hollow billet and the second hollow billet inserted in the first hollow billet, a pressure oriented axially of the two hollow billets is applied to the resilient member to bring the outer wall surface of the second hollow billet into intimate contact with the inner wall surface of the first hollow billet, and opposite ends of the two hollow billets are joined and sealed. The hollow billets thus joined into a unitary structure are subjected to hot extrusion, cold working and heat treatment to produce a composite tube of reduced diameter and reduced thickness, and the inner and outer wall surfaces of the composite tube are ground.

    摘要: A data processing device for writing various kinds of rule data easily and rapidly in a pixel image memory. Rule pattern store means stores a plurality of kinds of rule patterns in the line direction and a plurality of kinds of rules in the digit direction, the line and digit directions respectively being associated with those of an image data store area of the pixel image memory. Means is provided for selecting one of the rule patterns stored in the rule pattern store means and moving it to the pixel image memory. In response to a command entered through an input device, desired one of the rule patterns is selected and only a desired length of the selected rule pattern is moved.

    摘要: A method and apparatus for making a cylindrical package in which a cylindrically shaped coil of a long steel strip having a peripheral surface, two end surfaces and a hollow cylindrical center is completely wrapped with a wrapping sheet material so as to have neatly folded closures on both end surfaces with a ring member inserted into the cylindrical hollow center of the coil. At first the wrapping sheet is wrapped around the coil so as to project from either end of the coil by a length l greater than the thickness t between the outermost layer and the innermost layer of the coil. The projecting portions are folded onto the end surfaces by pusher plates with pleat forming rods provided therebetween to form crease lines. The pleated portions of the sheet are flattened onto the folded sheet by the sliding action of pusher plates, and then a ring member is fitted into the cylindrical hollow center of the coil at either end with the edges of the folded sheet pressed underneath so that the wrapping is completed without use of an adhesive.
