Taper etching by which the end face by etching becomes an inclined surface inclined toward a tip edge 2a is performed to a part stuck onto a magnetic gap forming part in the vicinity of the tip edge 2a of the lower magnetic material 2 in each laminated and formed insulating layer 3, 5 and 7. Subsequently, with respect to the insulating layer 3 left by the taper etching, an etching treatment having selectivity to the lower magnetic material 2 is performed, and the insulating layer 3 is removed completely. After removing completely each insulating layer 3, 5 and 7 stuck onto the magnetic gap forming part, an insulating film 10 is stuck and formed with a high accuracy, and also an upper magnetic material 9 is laminated and formed.

Title: Test system for data processor
Inventor: ARAI TOSHIMASA
IPC: G06F11/22
Filed: 1990-08-23
Abstract: PURPOSE:To execute safe maintenance work to a computer system whose high reliability is requested by obtaining judgement whether an operator has high skill in test environment judgement and controlling the execution of a test program. CONSTITUTION:When the permission of execution is recognized in a step '1', the execution of the test of a step '6' is started. When the judgement is not given, a system proceeds to a step '2' and the judgement is requested to the operator. When the operator judges it to be 'OK', the system proceeds to a step '3'. In the step '3', operator ID is inquired to. Namely, an operator who has the high skill and who can grasp the operation conditions of the system, constitution conditions and the conditions of the fault of hardware can be discriminated from ID of a general operator. In a step '4', the operator ID is checked to be that of the operator of a high level or not. When it is not that of the operator of the high level, a system proceeds to a step '5' and the test is interrupted. When it is judged to be that of the operator of the high level, the execution of the test of a step '6' is started.

Title: Mobile terminal position information transfer method and device therefor
Inventor: KAWARABAYASHI YUTAKA
IPC: H04W60/06
Filed: 1997-08-18
Abstract: PROBLEM TO BE SOLVED: To shorten connection impossibility informing processing time at the time of call termination in the state of leaving to the outside of the service area of a mobile terminal of a small scale mobile communication network or power source OFF within the area. SOLUTION: By the transmission of position information registration cancellation request signals by the mobile terminal 1 when the reception level of control signals from a base station 2 becomes lower than a prescribed value or a power source is turned OFF within the area, a position information data base 5 cancels the registration of a position information management table 6. When an incoming call arrives at the mobile terminal, the position information management table is retrieved, and since position information registration is canceled, the incoming call is immediately connected to a connection impossibility talkie and thus, the time required because connection impossibility can not be confirmed until calling connection is performed and forced disconnection is performed as before is avoided.
Patent JP-H0386932-A (JP)
Title: Optical information processor
Inventor: ENDOU TAKEYA
IPC: G11B7/09
Filed: 1989-08-30
Abstract: PURPOSE:To reduce the cost of a device by providing a means which generates an AT error signal with the aid of digital processing after A/D conversion and a means which varies the dynamic range of an A/D conversion means according to the magnitude of the AT error signal. CONSTITUTION:A DSP part 5 gradually makes the reference voltage of an A/D part 4 smaller from an initial value so that the amplitude value of the AT error signal becomes a prescribed value which is previously set and makes the dynamic range of the A/D part 4 narrower through a D/A part 7. When the amplitude of the AT error signal becomes the prescribed value, the DSP part 5 fixes the reference voltage of the A/D part 4. Then, the value thereof is used thereafter. Due to that, even when a disk 1 whose reflectance is different is used, the AT error signal having the fixed amplitude can be obtained. Besides, the gain of the error signal of tracking servo can be kept constant. Thus, even the A/D converter 4 whose bit length is short and which is inexpensive can be used and the cost of the device is reduced.
