Abstract: PURPOSE:To obtain a diffraction grating used for a branching filter for <=1,000Angstrom  wavelength, by providing an easily oxidizable layer on a substrate, forming a grating pattern for masking, etching away the easy-to-oxide layer, and then performing an oxidation treatment. CONSTITUTION:On a substrate 2, an easily oxidizable layer 3 Al, etc., is provided and then a masking grating M with a striped grating pattern of synchronism 2v is formed. Then, only a masking striped body (m) with width (e) and an easily oxidizable material grating (h) beneath it are formed the substrate is dipped in about 60 deg.C warm water to carry out an oxidation treatment. The oxidation proceeds from both sides 9 and 10 where the warm water comes into contact, thus obtaining a linear oxide body (g) with width D. Then, the striped body (m) for a color mask is etched away and the remaining layer (h) is removed similarly to obtain a precise diffraction grating of only the linear oxide body (g).

Abstract: PROBLEM TO BE SOLVED: To provide a reset switch circuit which prevent its action from being erroneous because of abnormal shock and vibration, and enhances safety at the leakage, excess current and abnormal over-heating by letting an electrical breaking condition be kept on. SOLUTION: When leakage, excess current and abnormal over-heating take place by some reasons in electric equipment A to which electricity is supplied through a relay 8, let such condition be sensed by a specified sensor, and let a trigger signal be generated.

Title: Magnetic recording medium
Inventor: TAKAGI HIROTSUGU
IPC: G11B5/66
Filed: 1985-05-15
Abstract: PURPOSE:To obtain a magnetic recording medium having excellent surface characteristics such as running stability, durability and lubricity by providing a thin tantalum carbide film on a thin magnetic metallic film. CONSTITUTION:This magnetic recording medium is constituted of a non- magnetic substrate 1, the thin magnetic metallic film 2 and the tantalum carbide film 3. The thickness of the film 2 is preferably 0.05-1.0mum. The film 3 can be formed by a CVD, plasma CVD, reaction vapor deposition, sputtering, reaction sputtering or ion plating method. The tantalum carbide is exemplified by TaC, Ta2C and the eutectic mixture thereof. The reliability of the wear resistance and corrosion resistance improves but the space from a head increases and a so-called 'spacing loss' increases if the thickness of the film 3 is large. The long-period durability is lost if the thickness is too small. The preferable range of the thickness is therefore 50-300Angstrom .

Abstract: PURPOSE:To enable the generation of noise during operation, according to the method wherein, in a title device used in a cooling fan for car and the like, a torque transmission area and fluid feed are controlled by the use of the thermal force of wax reacting to an atmospheric temperature. CONSTITUTION:As a result of an atmospheric temperature being increased to higher than a given value, wax 13 is thermally expanded to expand a dia phragm 14, and a piston 18 is extruded to the front wheel 6 side.
