IPC: G11B5/31
Filed: 1984-08-10
Abstract: PURPOSE:To obtain a thin film magnetic head prevented from magnetic saturation and the leakage of magnetic flux at the leading end part of the head and having writing characteristics by forming the taper angle of an organic insulating film on the leading end part of the head more sharply than that of a core contact part. CONSTITUTION:A magnetic film 3 to be a lower core material is formed on a substrate 2 having an insulating film 1 and photoetched to form a pattern of the magnetic film 3. Then a gap material 4 and a conductive coil 5 are successively formed on said pattern. An organic insulating film 6 is formed over the gap material 4 and the coil 5, and then a negative photoresist pattern 7 is formed on the film 6. After forming a negative photoregist pattern 8 more thickly than the resist film 7, the insulating film 6 is etched by using the resist films 7, 8 as masks. Consequently, the taper angle of the film 6 on the magnetic recording medium side can be made larger than that of a connection part between the core 3 and an upper core 9. Then the upper core 9 and a projection film 10 are successively formed. Thus, the head is prevented from the leakage of core magnetic flux at its leading end part and the magnetic saturation of the core connection part and its writing characteristic is improved.

Title: Fuel injection controller in internal combustion engine
Inventor: BETSUSHIYO HIRONORI
IPC: F02D41/12
Filed: 1981-10-20
Abstract: PURPOSE:To reduce substantially rotational frequency of an engine in the resumption of fuel injection to improve fuel consumption by reducing fuel injection amount in a predetermined reduction ratio when negative pressure in a brake booster is smaller than a set value. CONSTITUTION:An electronic control unit 14 detects depressing force of a brake pedal 30 through reduction ratio of negative pressure in a transformation chamber 25 of a brake booster 21 when the brake pedal 30 is depressed, irrespective of the signal of a rotational frequency sensor 20, so that fuel injection amount is rapidly reduced in response to the recution ratio. Thus, even when the brake pedal 30 is depressed and fuel injection action is stopped, the rotation of the engine is restrained by the action of depressing the brake pedal so that shock is restrained. Also, as the depressing force is increased the fuel injecting action is sooner stopped, and further even when the rotational frequency of the engine is low, the fuel injecting action is stopped so that fuel consumption can be improved.
