Title: Fabrication of thin film transistor matrix
Inventor: OGATA HIROSHI
IPC: H01L29/786
Filed: 1994-03-10
Abstract: PURPOSE:To suppress the voltage between a gate electrode and a gate bus line within a predetermined range by applying a voltage between the gate elec trode and the gate bus line and between a drain electrode and a drain bus line when the gate electrode and the gate bus line are subjected to anodic oxida tion. CONSTITUTION:A transparent insulating glass substrate 11, on which a thin film transistor matrix is formed, is immersed along with a platinum electrode 27 into an aqueous solution of ammonium phosphate within an anodic oxidation system 26. A voltage of 140V, for example, is then applied such that a gate electrode, a gate bus line 221 and a drain lead-out pad 24 exhibit positive polarity whereas the platinum electrode exhibits negative polarity and a current of 1mA/cm<2> 15 fed in order to subject the surface of the gate electrode and the gate bus line 221 to anodic oxidation. Consequently, Al2O3 is deposited on the surface of the gate electrode and the gate bus line 221 and leak current is suppressed between the gate electrode and the gate bus line 221 and between the drain electrode and drain bus line 161.

Title: Magnetic recording device
Inventor: ARIGA EIKICHI
IPC: G11B5/02
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To set an optimum recording current by detecting the magnetic permeability of the recording magnetic layer formed on a record medium and setting the recording current of a magnetic head to the recording current for magnetic permeability of the detected recording magnetic layer based on the output to judge the actual value of the coercive force of the medium in a short time without necessitating a discriminating mark. SOLUTION: In the case of performing a recording to a record medium and the reproducing of the medium, when the record medium is inserted from a port 19 to a magnetic recording device 9, an inserting sensor detects it to actuate a prehead 26 and a sensing sensor 1. The head 26 reads out magnetic data of the recording magnetic layer of the medium to judge whether the medium is at a prescribed position or not and whether it is a normal medium or not and it is inserted in a correct direction or not. When the read data are normal, the medium is transported to the inner part by actuating a driving motor and an exciting current is impressed on a coil by actuating an exciting circuit. Since a magnetic flux is guided to the medium through the recording magnetic layer and it is returned to the exciting coil, the leakage of the magnetic flux generated from the coil is made to be small.

Abstract: PROBLEM TO BE SOLVED: To keep a high power conversion efficiency when the load of a switching power supply is light. SOLUTION: The collector/emitter of a switching transistor 50 which is controlled by the output of a frequency dividing circuit 51 is connected to the base/emitter of the switching transistor 36 of a ringing choke converter(RCC) circuit 48. A voltage which is generated in the feedback winding 35c of a transformer 35 is supplied to the frequency dividing circuit 51 through the light receiving side 53a of a photocoupler 53 which is continuous when a low level signal is supplied to a control input 57 and the light emitting side 53b of the photocoupler 53 emits a light. The switching transistor 50 is cut off for a fractional period of the voltage waveform generated in the feedback winding 35c and the switching transistor 36 of the RCC circuit 48 is in a continuity enable state.  As a result, the self-oscillation frequency of the RCC circuit 48 is lowered and the increase of the switching loss can be avoided.
