Title: Preparation of magnetic bubble element
Inventor: MIKAMI MASAO
IPC: H01F41/14
Filed: 1979-10-05
Abstract: PURPOSE:To provide a wider range of the material selection and the heat-treatment conditions for a magnetic bubble element, which transfers bubbles by the rotating magnetic field through the surface, by growing an epitaxial film to be a drive layer before a bubble-maintaining layer. CONSTITUTION:On a substrate 1 of Gd3Ga5O12, a garnet epitaxial film 2 is grown, on which SiO2 is provided by sputtering and a pattern 3 is formed by photolithography. Then the pattern 3 is treated with heat in O2 gas to obtain a pattern portion whose magnetization direction is perpendicular to the surface and the rest whose magnetization direction is parallel to the surface. Then the pattern 3 is etched to remove the SiO2 pattern, and a bubble-maintaining layer 4 is grown. Applying to this a magnetic field H parallel to the surface causes the film 2 to be magnetized and charged walls to be produced on the right and left sides of the outside of the vertical portion, so that a bubble 5 is caught by either of them. Said procedure eliminates the need for separately growing films, a film whose magnetic characteristics are readily changed by heat treatment, and a film hard to change. Consequently, a wider range of material selection and the heat-treatment conditions can be provided.

IPC: F04C18/02
Filed: 1982-07-28
Abstract: PURPOSE:To prevent intrusion of oil at the bottom of an enclosed container into a suction pipe positively when operation of a compressor is stopped, by keeping the pressure in an enclosed space between a fixed scroll and a revolving scroll higher than the suction pressure by leaking a part of pressure in a discharge chamber into said enclosed space between the fixed scroll and the revolving scroll. CONSTITUTION:When operation of a compressor is stopped and a valve plate 24C of a check valve 24 comes into tight contact with a seat surface 24B, part of high-pressure gas in a discharge chamber 11 is leaked into an enclosed space 4 formed between a fixed scroll 2 and a revolving scroll 3 via a small hole 24E formed in the valve plate 24C and a discharge port 10. Since, with such an arrangement, the gas in the discharge chamber 11 flows back into the enclosed space 4 and pressure in the enclosed space 4 becomes higher than the suction pressure, it is enabled to prevent oil (not shown) at the bottom of an enclosed container from entering into a suction pipe (not shown).
