Title: Rotation-balance measuring apparatus of fluid machine
Inventor: KAWADA YUTAKA
IPC: F04B51/00
Filed: 1984-01-10
Abstract: PURPOSE:To obtain a rotor having good balance as a rigid body and for a fluid, by the constitution, in which the rotaty balance is measured, with the rotor being placed under a no-load state and an appropriately loaded state. CONSTITUTION:At first, an impeller 2 is rotated without a load. Unbalanced centrifugal force is measured by a rotary balance measuring device 3. After the balance is obtained, a water flowing tank 1 is filled with water and the impeller 2 is rotated. When a load is imparted to the impeller 2 by a loading device 4, the unbalanced force, which is yielded under the loaded state, is measured by the measuring device 3. The loading device 4 is formed in a cylindrical state by porous plates 5, whose side is made of two plates. The upper part and the lower parts are tightly closed except for the entrance hole for the impeller 2. The outer porous plate 5 can turned in the circumferential direction by a hydraulic device 6. The holes in the inner and outer porous plates 5 are deviated, and the area of the opening part is changed. Thus the load against the water flow can be adjusted. Therefore, the rotary balance can be measured under the appropriate loaded state.

Abstract: PURPOSE:To extend the life of a target and to uniformize the thickness of a thin film to be formed, by impressing a perpendicular electric field and magnetic field orthogonal therewith between a flat plate-shaped substrate and the target which are disposed in parallel with each other and moving the target in parallel with the substrate. CONSTITUTION:The substrate 7 and the flat plate-shaped target 1 which are spaced from each other are disposed to confront each other via an earth shield 17 in a vacuum vessel (not shown). The electric field is generated between both perpendicularly to the target 1 face and the magnetic field 8 orthogonal therewith is impressed therebetween by a magnet 2 disposed on the substrate 7 side of the target 1. High- density plasma is thereby generated on the substrate 7 side of the target 1 to sputter the target 1 and to form the thin film on the substrate 7. A supporting base 12 of the target 1 of the above-mentioned thin film forming device is so constituted that said base can be moved by means of a rack gear 13 and a pinion gear 14 engaged therewith when said gear is driven by a motor 15. The formation of the thin film is thereby executed while the target 1 is moved in arrow 16, 16a directions, by which the target 1 is uniformly sputtered and the change of the film thickness distribution with time is eliminated.
