Filed: 1986-07-18
Abstract: PURPOSE:To control the magnetic gap length and to improve the wear resistance to a metallic tape by sputtering a low-softening point glass on magnetic gap faces on which a high-softening point glass is sputtered and joining them by pressuring and heating. CONSTITUTION:After a high-softening point glass 6 whose softening point is higher than the crystallization temperature of an amorphous alloy is sputtered on magnetic gap forming faces 4 of a pair of magnetic blocks 1 and 2 consisting of magnetic materials, a low-softening point glass 7 whose softening point is lower than the crystallization temperature of the amorphous alloy is sputtered on magnetic gap forming faces 4. Magnetic gap forming faces 4 are butted to each other and are heated at a temperature which is lower than the crystallization temperature of the amorphous alloy and is higher than the softening point of the low-softening point glass, and the low-softening point glass 7 is fused to form a magnetic gap. Since the magnetic gap is formed with the high- softening point glass, a magnetic head is superior in wear resistance and has a coefficient of thermal expansion approximating that of magnetic materials and is useful for a high-coercive force tape like a metallic tape.

Title: Image forming device and its control method
Inventor: NAKAMURA SHIGEO
IPC: G03G15/20
Filed: 1999-06-16
Abstract: PROBLEM TO BE SOLVED: To obtain an image forming device performing appropriate initial operation at the time of restarting after jamming processing by controlling the initial operation of a fixing device after power is supplied to the image forming device based on the presence or the absence of jamming information stored in an information storage means. SOLUTION: Whether or not paper jamming is detected just before the previous cutoff of power supply is judged based on information stored in a jamming information memory (S31). When the jamming information just before the previous cutoff of the power supply is stored in the jamming information memory, that is, when the power supply is the one after the jamming processing, the temperature control of a fixing roller is started by starting energizing a heater by a mechanical control part (S32). Thereafter, the fixing roller is heated until surface temperature becomes 185 deg.C without separating or rotating the fixing roller. When a thermistor detects the temperature 185 deg.C (S33), the fixing roller is separated and starts rotation (S34). Thus, winding is prevented.

Title: Manufacture of semiconductor device
Inventor: INOUE DAIJIRO
IPC: H01L29/812
Filed: 1988-07-07
Abstract: PURPOSE:To make it possible to form an electrode with a width narrower than the width of a line which is obtained by photoetching using ultraviolet rays, etc., without forming a layer that suffers damage by implanting ions into an insulating film from the oblique direction to the substrate surface using a photoresist film as a mask so as to form an ion implanted region. CONSTITUTION:An insulating film 5 is formed on a substrate 1, and a photoresist film 6 is opened selectively, and with the photoresist film 6 as a mask ions are implanted into the insulating film 5 from the oblique direction to the substrate surface so as to form an ion implanted region 8. Accordingly, in case that the insulating film 5 where the ion implanted region 8 was formed is wet-etched, the ion implanted region 8 where the etching speed is higher is etched faster than other regions of the insulating film 5, and an oblique opening part 9 is formed at the insulating film 5. Accordingly, when forming this opening part 9, the necessity of using a reactive ion beam etching method vanishes, and it ceases to form a layer suffering damage near the substrate surface. Hereby, a gate electrode 10 with a gate length shorter than the line width capable of realization by photoetching can be formed.
