Title: Method of measuring position of corresponding die bolt
Inventor: IGUCHI KATSUHIRO
IPC: B29C48/08
Filed: 1984-07-27
Abstract: PURPOSE:To enable to measure easily a position of a corresponding die bolt, by blowing air against predetermined positions corresponding to positions of the die bolts on the surface of a plastic sheet moving on the surface of a lip or directly below the lip of a T die from one or a plurality of pieces of nozzles. CONSTITUTION:Air is blown against a lip 11A of the lower part of a certain die bolt 13 out of a plurality of the die bolts 13 by facing a nozzle 32 toward the lip 11A during molding of a sheet 12 by working an extruder 21. The lip 11A is either cooled or heated by abutting a thin flow of the air blown off through the nozzle 32 against the lip 11A. A flow, therefore, of a polymer flowing through a T die 11, generally, is reduced in case of cooling and increased in case of heating, or hardness becomes hard in case of the cooling and soft in case of the heating, through which a thickness of a sheet 12A is varied. When a variation of the thickness is detected by a thickness meter 23, a position corresponding to the specific die bolt 13 can be discriminated on a plane of the sheet 12.

Title: Nitrogen base gas soft nitriding method
Inventor: MATSUI KATSUYUKI
IPC: C23C8/24
Filed: 1986-07-05
Abstract: PURPOSE:To uniformly execute a soft nitriding treatment of a work at a low cost by using gaseous N2 as a base gas, adding a specific amt. of air to said gas during a heating up stage and executing an oxidation treatment, adding gaseous NH3 gas to the base gas and executing the nitriding treatment by adding gaseous ammonium in a holding stage. CONSTITUTION:The gaseous N2 is introduced into a heat treatment furnace and is used as the base atmosphere, then 0.5-5vol% air or 0.1-1vol% oxygen is added thereto in the heating up stage for the work before the holding stage to execute the nitriding treatment. A cutting oil sticking to the work and the added oxygen are brought into reaction by the addition of air or oxygen and the reaction product is removed mainly in the form of the gaseous CO2. The gaseous NH3 is then added to the atmosphere and the work is maintained at a prescribed temp., then the nitriding is executed by cracking the gaseous NH3 and generating the N2 in the holding stage just before the completion of the heating up stage. The stable nitriding treatment is thus executed by effectively using the costly gaseous NH3.

Title: Superconductive rotor
Inventor: IWAMOTO MASAHIKO
IPC: H02K55/04
Filed: 1981-10-02
Abstract: PURPOSE:To improve the balance of a superconductive rotor at the rotating time by burying an inside damper in the cover of a helium pressure container to form an inside shaft, thereby forming the inside shaft in a single structure. CONSTITUTION:An inside damper 4a is buried in the cover of a helium pressure container 3a to form an inside shaft 8b, and a reflecting plate 19 is provided on an outside shaft 6b. In this manner, a helium pressure container 3a in which the damper 4a is buried outside a torque tube 8 is formed at the inside shaft 8b, and it is not necessary to provide the inside damper 4a outside the container as the conventional one. In this manner, the shaft 8b is not necessarily formed in the conventional double, structure, but can be formed in a single structure, thereby improving the balance at the rotating time. Since the radiation heat shield can be performed not only at the damper 4a buried as the cover of the container 3a but at the plate 19, the radiation heat shield can be improved.

Title: Fixing device
Inventor: KOSUGI KENICHI
IPC: G11B15/30
Filed: 1983-08-31
Abstract: PURPOSE:To fix assuredly a reel and to read and write satisfactorily the information by providing a stopper member having a height from a base higher than a projected member, and forming plural projections made of an elastic material such as rubber, etc. on the surface of the projected member in the front-back direction. CONSTITUTION:A pressure cam 12 is turned around a shaft 18 and projected toward Y, i.e., a annular matter 11 after a reel 16 is set to a retainer 13. Therefore the matter 11 is deformed and the reel 16 is totally shifted toward Y together with a contact secured between the outer circumferential surface 11b of the matter 11 and the inner circumferential surface 16a of the reel 16. When the movement of the reel 16 is stopped by a positioning block 10, the reel 16 stops in a close-touched state via the matter 11 between the cam 12 and the outer circumferential surface of the block 10. Thus the horizontal movement of the reel 16 is stopped, and at the same time the vertical movement of the reel 16 is also stopped by a rotary disk 15 and the matter 11. Thus the reel 16 has no tilt to the disk 15 and therefore the height of a tape is kept at a fixed level.
