Title: Production of thin-film magnetic head
Inventor: ORIHARA HIDEJI
IPC: G11B5/31
Filed: 1991-10-28
Abstract: PURPOSE:To improve the magnetic characteristics of the thin-film magnetic head by constituting this head in such a manner that a heat treatment can be executed without generating internal stresses after the formation of core layers. CONSTITUTION:Insulating layers 2 to 7 are formed by converting a material essentially consisting of TiO2 to an amorphous material. For example, the substrate 1 side is forcibly cooled to <=200 deg.C and the material essentially consisting of the TiO2 is released by high-speed sputtering at >=50Angstrom /min to form the layers. The heat treatment for imparting magnetic anisotropy after the formation of respective cores 8, 9a, 9b, 10 is enabled by the high heat resistance of the insulating layers 2 to 7. Since this material is nearly equal to the coefft. of thermal expansion of the material for the substrate 1, etc., the deterioration in the magnetic characteristics arising from the generation of stresses at the time of the heat treatment is prevented. Further, the perfect insulation by a uniform coating and the working with high accuracy at a high rate by dry etching are attained.

Further, the oscillation output laser beam is divided into two and the two divided beams are made to pass through respective two light paths having different light path lengths and then synthesized again to make the two beams interfere each other. With this process, the beam component having the same frequency as the frequency of the electromagnetic wave contained in the intensity change created in the synthesized laser beam is demodulated and outputted as a signal. With this constitution, the frequency of a semiconductor laser beam whose spectrum width is not narrow and whose oscillation frequency is not stable can be modulated/demodulated stably.

Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To preliminarily judge by self diagnosis an abnormality of a system for measuring ammonium ions as a trimorphic nitrogen, nitride nitrogen and nitrate nitrogen. SOLUTION: A reaction reagent is measured and mixed after a span calibration solution is sent into a pass canaliculus (S3-S6). The mixed reagent is injected into a canaliculus (S7) and added to a self diagnosis standard solution. After mixed by a mixer, the solution is displaced by a gas-liquid separation tube to a gas phase as an NO gas and is let to react with an ozone gas at a chemical emission detect part. A quantity of emitted light is detected (S8). For an abnormality diagnosis, after a coefficient of variation CV is operated (S11 and S12), the coefficient of variation is compared with a stabilization diagnosis reference value (S13). When the coefficient of variation satisfies the reference value, the self diagnosis result is judged as normal, and then compared with a measurement accuracy reference value (S14 and S15).  When the self diagnosis result is within a measurement accuracy range, the self diagnosis is completed and a steady measurement state is restored (S16-S18).

CONSTITUTION:The power failure detection signal 108 and the communication stop detection signal 109 are inputted to a first-come decision section 10 to decide which of both the signals comes faster timewise. A power failure detection signal 108 from a power failure detection signal 108 is inputted to a timer circuit 16 to generate a delay signal 111 after a time T4. The time is selected as power failure detection time T2< emergency power supply hold time T1, and emergency power supply hold time T1+communication stop detection time T3< communication stop detection sampling time T4.
