Title: Spinning device
Inventor: UCHIDA YUJI
IPC: D01H1/115
Filed: 1991-01-17
Abstract: PURPOSE:To improve productivity and reduce production cost by directly forming a twist yarn from a spinning device without using a doubling machine or twisting machine. CONSTITUTION:A fiber bundle is introduced through a front roller 1 into a casing 2 and guided into the inlet of each spindle 8 by jet air stream of a nozzle 11 and simultaneously force for separating from the fiber bundle is given to a fiber constituting the above-mentioned fiber bundle positioned on the circumference of a guide member 16. When the rear end of the fiber is released from the above-mentioned front roller 1, fiber is wound in spiral state around the fiber bundle traveling through a conical part of spindle 8 while turning on the inlet of the abovementioned spindle 8 several times by action of pressurized air turning stream to form a spun yarn and the spun yarn is passed through fiber bundle passage 9. Thus, spun yarn is spun out one by one from each spinning unit 4 and simultaneously when the spun yarn is pulled out from a delivery roller 17 by rotation of rotator 3 inserting plural spinning units 4, spun yarn spun from the above-mentioned spinning units 4 is mutually twisted to form twisted yarn.

Title: Cladding pipe for boiling water reactor fuel
Inventor: NAKAMURA YASUE
IPC: G21C3/06
Filed: 1988-01-29
Abstract: PURPOSE:To intensify the flow of a liquid from to the surface of a cladding pipe to be loaded with fuel pellets just before the up stream of a spacer and to maintain and uniformize the liquid film so that the thermal critical output is improved by providing a rough surface part to a part of the outside surface of the above-mentioned cladding pipe. CONSTITUTION:Metal powder 3 is stuck by thermal spraying to a part of the surface of the cladding pipe 1 for fuel to form the rough surface part 2 on said part. The reason for limiting the point to be formed with the rough surface part 2 to a part of the surface of the cladding pipe 1 is because the effect of improving the flow of the liquid film (two-phase flow) is expected and there is no effect on the single-phase flow and slag flow near the inlet of a bundle. There is, therefore, no need for providing the rough surface part 2 over the entire length of the cladding pipe 1 and the partial provision of said part on the up stream side of the spacer is adequate in terms of economic efficiency of a working cost. Since the flow of the liquid film to the surface of the cladding pipe is thereby intensified, the generation of dry-out is prevented and the thermal critical output is improved. Wrapping of a metal wire in place of the metal powder around the cladding pipe or working of the above-mentioned to a porous surface is equally well.

CONSTITUTION:In a magnetron sputtering apparatus having a cylindrical magnet 1 on the rear face of a target 4, the cylindrical magnet 1 is constituted in such a manner that plural pieces of doughnut-type magnets having holes in disks are combined into a multilayered form.
