Title: Magnetic head
Inventor: FUJII MASATAKA
IPC: G11B5/23
Filed: 1987-10-02
Abstract: PURPOSE:To obtain a magnetic head coping with a high coercive force magnetic recording medium with high productivity and high accuracy in the track width by forming a track width regulating slot to at least one high magnetic film. CONSTITUTION:High saturation magnetic flux density magnetic films 3, 3' are formed on a magnetic or nonmagnetic base and track width regulation slots 9, 9' corresponding to the track width are processed to the high saturation magnetic flux density magnetic fluxes 3, 3' prior to the packing of glass 4. Thus, the fluctuation of the track width due to the dispersion of the processing quantity is prevented by the track width regulating slots 9, 9' in finishing the magnetic gap mating face by polish processing after the glass is packed. Thus, the manufacture yield is improved and the magnetic head with high productivity and suitable for high recording density is obtained.

Filed: 1988-10-04
Abstract: PURPOSE:To facilitate a plate-making operation in pad printing and eliminate the need for a squeegeeing step using a doctor blade by making a plate from one of a pair of electrodes through utilizing such a property of a sticky ink that the ink becomes non-sticky to the electrode when a voltage is applied to the ink by the pair of electrodes. CONSTITUTION:A conductive printing plate 4 comprising an insulator pattern 2 on the surface of a conductive base 1 is coated with an ink 3 in a uniform thickness by a coating means 5. A conductive rubber 7 fixed on a conductive printing plate 6 is pressed against the surface of the ink 3 applied to the printing plate 4, and a voltage is applied between the printing plate 6 and the printing plate 4 through the rubber 7 and the ink 3 by a power supply 8. The ink applied to the conductive surfaces becomes non-sticky on the cathode side, so that when the rubber 7 is separated from the plate 4, an ink pattern 3a is formed on the surface of the rubber 7. On the other band, the ink 3 applied to the insulator parts 2 is not supplied with any voltage, and does not become non- sticky, so that the ink is left as it is on the plate 4, thereby forming an ink pattern 3b. When the ink pattern 3b is transferred, an image reverse to the ink pattern 3a is obtained.
