Filed: 1979-07-26
Abstract: PURPOSE: To shorten the time of transition from electric power feed to normal operation, by connecting diodes in parallel to a feedback resistance for the amplification output of an amplification part.  
     CONSTITUTION: To the inverted input terminal of amplifier AMP, input resistance R 2  and capacitor C 2  are connected and then the output terminal of transistor TR 2  is connected to the inverted input terminal by way of the parallel circuit of feedback resistance R 3  and diode d 1 . When constant voltage power source part S is connected, amplifier AMP of amplification part A 2  charges rapidly capacitor C 2  of high capacity with a time constant, determined by resistance R 1  and capacitor C 1 , by way of the parallel circuit of resistance R 3  and diode d 1  between output transistor TR 2  and the inverted input terminal. Therefore, the inverted input terminal rises and gets stable in an extremely short time. Thus, the time of transition from electric power feed to normal operation can be shortened by the simple constitution.

Title: Wafer aligner
Inventor: MORITA KAZUHIRO
IPC: G01B11/00
Filed: 1993-04-22
Abstract: PURPOSE:To detect the center position of orientation flat indenpendently of an amount of eccentricity with high accuracy by sampling a component dependent on an amount of eccentricity from the data of a wafer external edge position and detecting the center position of orientation flat from the data obtained by excluding the component dependent on an amount of eccentricity from the data of the wafer external edge position. CONSTITUTION:A wafer 2 is rotated to latch the data of an external edge position for every fixed angle of the wafer 2 into a control device 13. The direction of the orientation flat 14 of the wafer 2 and an eccentric position against an O-table 1 are detected from the data of an external edge position for every fixed angle of the wafer 2 with operation processing. The component dependent on an amount of eccentricity is excluded from the data of a wafer external edge position to detect the center position of orientation flat from the data after exclusion. Thereby, even when the wafer 2 absorbed with vacuum to the O-table 1 has eccentricity, the high-precision detection of the orifla center position can be realized.

For example, an atmosphere is once evacuated to a vacuum state to deair the oxygen in the vicinity 1' of the surface. Then, an Si nitride film is formed on the upper surface in a thickness of 20 Angstrom , for example, by a vapor phase method and so on. An ion-implantation is performed in this film. Oxygen is doped in a concentration of 1X10<17>cm<-3>-1X10<21>cm<-3> in such a way that an accelerating voltage is weakened to 10-30 KV and the oxygen concentration becomes constant. Moreover, the whole is subjected to heating treatment in oxygen at 600 deg.C, for example. The oxygen concentration in the vicinity of the surface becomes the same oxygen concentration as that in the interior in spite of a fact that the oxygen is ready-deaired.

Filed: 1992-04-16
Abstract: PURPOSE:To obtain an excellent over write (o/w) characteristic by preventing crosstalk in a magnetic head for an FDD having two or more of core chips with different recording/reproducing density from each other in one slider. CONSTITUTION:Metal films 10, 11 consisting of magnetic material having a low saturation magnetic flux density is provided on the erasure gap edge position of an erasure core chip 3 for 1MB or 2MB, and a gap length at a reproducing time is made 0.05mum-0.1mum. Thus, the crosstalk due to a signal regenerated by the erasure core chip 2 for 1MB or 2MB is eliminated at the time of a high density recording and reproducing. Thus, even when a magnetic shield plate 9 is made thin and reduced in size, since the crosstalk from the 1MB or 2MB core chip 2 at a reproducing time is reduced, no reproducing error occurs. Further, since the shield plate is made thin and reduced, in size, sufficient magnetic flux is generated from the core chip 4 for the high density recording at an o/w time as well, and no o/w fault occurs, as well.

Title: Method for measuring temperature difference in magnetic field
Inventor: NARA KOICHI
IPC: G01K13/00
Filed: 1989-04-17
Abstract: PURPOSE:To measure the temperature difference in a magnetic field by arranging a plurality of resistance measuring sensors whose characteristics are aligned in about 0.1% in a symmetrical pattern, and measuring the resistance ratio with a bridge. CONSTITUTION:Temperature sensors 3 and 4 whose characteristics are aligned in about 0.1% are arranged for objects 1 and 2. The reference signal output from a lock-in amplifier 11 is imparted to the temperature sensors 3 and 4 through a shielded transformer 9 in a shield box 10. The output voltages are taken out of both ends and the intermediate part with lead wires. The voltage from both ends is applied to a divider. The difference between the voltage from the intermediate part and the output of the divider is added to a differential input 12 of the lock-in amplifier 11, and phase detection and amplification are performed. In this constitution, the balance of a bridge is not affected with resistances 5 - 8 of the lead wires. In the case of a Pt thin-film resistance thermometer, the effect of a resistance R is R=R(T)X(1+aH<2>). When the dispersion (a) of a raw material is small, the effect is disregarded even in an intense magnetic field, and the temperature difference can be measured.

Abstract: PROBLEM TO BE SOLVED: To allow hot air stagnating at a back space to escape in the direction of a front ceiling efficiently by setting a blind plate for preventing the release of hot air flowing into a hot air release hole from changing its direction. SOLUTION: A blind plate 21 is formed by cut bends being bent with a downward inclination shape in the direction of a back space 3 or with an upward inclination shape in the direction of the inside of a room from the lower hole edge of a hot air release hole 11 while preventing the release of hot air flowing into a hot air release hole 11 from changing its direction, more specifically while being connected to the upper hole edge of the hot air release hole 11.
