Title: Method of manufacturing iii-v group compound thin film
Inventor: YODO TOKUO
IPC: H01L21/20
Filed: 1994-02-28
Abstract: PURPOSE:To improve the crystallizability of the III-V group compound thin film by a method wherein, after epitaxially growing a III-V group compound on a single crystalline substrate, a thin film comprising a hard material in the higher melting point than that of the compound is grown to be high temperature heat-treated later. CONSTITUTION:After the temperature of an Si substrate 201 is lowered down to 400 deg.C, the shutter of an As Knudsen type cell 18 is opened to irradiate the surface of the Si substrate 201 with As molecular beams and then another Ga Knudsen type cell 17 is opened to start the epitaxial growing step of GaAs for the formation of a GaAs thin film 202. Successively, the sputter of the other Si Knudsen type cell 19 is opened to form an Si thin film 203 on the thin film 202. Next, the temperature of the Si substrate 201 is raised upto 900 deg.C for heat treatment and then lowered down to 580 deg.C. At this time, the Si thin film 203 fills the role of a cap material in the high temperature heat treatment step so that the re-evaporation of atoms from the GaAs thin film 202 may be avoided thereby enabling the crystallizability to be improved.

IPC: G11B15/02
Filed: 1978-03-15
Abstract: PURPOSE: To eliminate software accident of no signal recording by having a signal detector which detects the presence or not of the video signal to be recorded and forcefully shifting to a stop state when the video signal does not exist.  
     CONSTITUTION: The output signal of 14 having detected the presence of the video signal causes the recording mode to be continued to record the video signal and audio signal in a magnetic tape becuase a stop mode driving circuit 17 is not operating. On the other hand, when the video signal does not exist, the output signal of the signal detecting circuit 14 becomes L and the output signal of a gate circuit 16 becomes L despite the suggestion of the recording mode by a sequence control part 15. This causes the stop mode driving circuit 17 to operate, then the mechanism part which has been mechanically loading the magnetic tape is released by a plunger 18 and the stop mode is set.

Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To configure a polarity inversion detection circuit as a monolithic IC by configuring an edge detection circuit without the use of a capacitor with a large capacitance. SOLUTION: A full wave rectifier circuit 20 applies full wave rectification to a current flowing to a communication line and provides an output of a voltage with a constant polarity from its positive and its negative terminals. First and second edge detection circuits 30A, 30B detect a polarity inversion edge of a start or restoration signal to provide an edge detection trigger current. A detection signal generating section 40 synthesizes the 1st and 2nd edge detection trigger current to outputs a detection signal denoting the provision of a start signal or a restoration signal to a terminal. A holding circuit 50 holds polarity inversion information set by the detection signal and outputs it.  Since no capacitor is employed for the polarity inversion edge detection circuit, the circuitry is proper to circuit integration and no current is supplied except edge detection, then the configuration of low power consumption is attained.

Or only an insulating spacer part in particular is covered with a wider tape-like porous high polymer material than the width of an insulating spacer 23 for insulation. The dielectric constant of the porous high polymer material is smaller than that of the coating insulating material of the flat-type wire 22. Thereby, a very small gap in the rail side of the outermost coil of the winding is eliminated to make a transformer with a high withstanding voltage. Besides, an insulating distance is decreased, so that a transformer which is thin in insulating thickness and high in thermal effect and reliability can be obtained.
