Abstract: PURPOSE:To reproduce a signal recorded with high density on a narrow track width while keeping high sensitivity and excellent S/N by laminating a primary side and a secondary inductance element on a thin film magnetic substance to form a high frequency coupling circuit. CONSTITUTION:The secondary inductance element 6b, an insulation layer 7 and a primary inductance element 6a are laminated on a thin film magnetic substance 5, and the elements 6a, 6b and the magnetic substance 5 from the high- frequency coupling circuit. The elements 6a, 6b are made of a band-shape thin film conductor, the element 6a is formed vertically on a magnetic recording medium 3 and the element 6b is formed in a track width direction orthogonal thereto. When the change in the high-frequency characteristic of the magnetic substance 5 is produced by a magnetic field from the signal magnetization on the recording layer 1 and a tensor permeability is generated, a strong electromagnetic coupling is generated and a large change in the high-frequency signal output appears at the secondary side. A signal reproducing output 12 is given to a peak detection circuit 11 through the said change.

Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To make satisfactory shaking-off possible for viscous liquid while preventing dripping and to increase a supply flow rate while making disassemly and cleaning easy with mixing of particles prevented by a method wherein the shape of a liquid supply nozzle is made up in a compressed nozzle in an ellipse having specified measurements respectively in diameters in the long span and the short span. SOLUTION: The shape of a nozzle port 1b of a compressed nozzle A is made up in an ellipse wherein the major axis (a) is set within a range of 2.0-100.0 mm while minor axis b is set within a range of 1.0-5.0 mm. As viscous liquid being discharged out of the nozzle port 1b is spouted in the form of flattened fluid formed along the compressed shape of the port, shaking-off can be improved for the viscous liquid while preventing dripping because of surface tension of the viscous liquid at the nozzle port 1b produced by reduction of the minor axis b and viscosity resistance arising from friction, and the flow rate in supply can be increased with the measurement of the major axis (a) set large. Furthermore, as no sliding part is provided at the inside of the nozzle, mixing of particles caused by wear can be prevented.
