Inventor: WAKAI KUNIO
IPC: G11B5/85
Filed: 1982-12-30
Abstract: PURPOSE:To obtain efficiently a magnetic recording medium which has superior coercive force and squareness by vapor-depositing a ferromagnetic material at a specific angle or more of incidence on a substrate which moves along the circumferential surface of a cylindrical can in a vacuum atmosphere and blowing a reactive gas to the minimum incident angle part. CONSTITUTION:While the substrate 4 such as a resin film is moved from a supply roll 5 to a take-up roll 8 along the cylindrical can 3 in a vacuum tank 1, the ferromagnetic material from a ferromagnetic vaporizing source 9 is vapor- deposited on the substrate obliquely at a >=20 deg. angle alpha of incidence by an antiadhesion plate 11 provided under the can 3, and a reactive gas such as gaseous O2 is blown from a gas intake pipe 12 to the part where the angle of incidence of the magnetic material is minimum so that the distance from the tip of the nozzle 12 to the axial center of the can 3 is about 20cm and the ratio of gaseous O2 partial pressure and a vapor-deposition speed is 5X10<-5>-2X10<-8>.

IPC: G01N27/30
Filed: 1985-10-15
Abstract: PURPOSE:To obtain a gas sensor having high selectivity of gaseous hydrogen halide with high sensitivity and having a high response speed by disposing a reference electrode deposited with a thin film of pulverized metallic powder which does not react with halogen ions on the inside surface of a thin gas permeable film, counter electrode and working electrode consisting of a solid metallic piece which reacts with the halogen ions into an electrolyte. CONSTITUTION:The gaseous hydrogen halide passes through the micropores of the thin gas permeable film 6 deposited with the platinum black coating the outside surface of the working electrode (solid piece of silver) 3 existing on the cathode side on the inside surface and dissolves into the laminar electrolyte 1 interposed between the thin film and the working electrode 3. The halogen ions are oxidized by the surface of the working electrode and form a metallic halide. Since the working electrode 3 is maintained at a constant potential, the halogen ions are oxidized. On the other hand, the oxygen sticking to the platinum black, etc., forming the counter electrode 4 on the anode side is reduced. Electric current is generated between the two electrodes by such oxidation-reduction. The intensity of the current is proportional to the concn. of the gaseous hydrogen halide.
