Title: Electrostatic capacitance using displacement detecting circuit and rotary head type apparatus for reproducing magnetic recording
Inventor: ABE KAZUTAKA
IPC: G01B7/00
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To detect the position or displacement at high precision or to detect or adjust the head height and relative height highly precisely by holding error voltage generated by a current voltage transformer at the time of stoppage of an excitation signal and correcting the displacement detection voltage with the voltage. SOLUTION: A height of a magnetic head 5 is detected as a detected electrostatic capacitance 1 constituted of the objective face 3 of an actuator 4 to be detected in which the head 5 is mounted and a detection electrode 2. An excitation signal from a transmitter 7 is processed by a signal amplifier 8, transformers 10a, 10b, rectifier elements 11, 12 and flows in the capacitance 1 and a standard electrostatic capacitance 13. The detected current based on the difference of the capacitance 1 and the capacitance 13 is transformed into voltage and amplified by a current-voltage transformer 15. The output of the transformer 15 at the time of periodic stoppage of the excitation signal is error voltage at the time of off-set and held in a sample and hold circuit 16.  The displacement detection current is corrected with the voltage held in the circuit 16 by a differential amplifier 17 and becomes voltage output of which the height is detected highly precisely.

Title: Thyristor
Inventor: HASHIMOTO OSAMU
IPC: H01L29/744
Filed: 1978-03-31
Abstract: PURPOSE: To improve dv/dt rating and turn-off time by varying impurity density distribution near the inner circumference of a N layer from which a main cathode electrode is led out.  
     CONSTITUTION: With the width of l=1∼3 from the inner circumference of the 2nd N layer 16 where main cathode electrode 18 is led out, the diffusion depth for a N- type emitter is made shallower than that of any other place and at junction J 3  between layers 13 and 16, impurity density C np  is made greater than that at any other place. As a result, electron injection efficiency decreases near inner circumference 16a of layer 16a and at the time of sudden rise-voltage application or of turning off, abnormal turning on will never occur at inner circumference 16a. Further, since turn-on sensitivity inside of the main SCR is low, the area of an auxiliary SCR can be made small, so that the area of the N layer can be increased relatively where the main cathode electrode is led out.
