Title: Quantum fine line structure and formation thereof
Inventor: KAMEI HIDENORI
IPC: H01L29/778
Filed: 1988-02-16
Abstract: PURPOSE:To make high density quantum fine lines and sufficiently isolate those lines by forming a plurality of stripe-shaped ridge parts and groove parts on a carrier storage layer, and doping a second conductivity type impurity into a carrier supply layer of the bottom and side of the groove. CONSTITUTION:A semiconductor crystal growth layer 6 comprising undoped Al0.48In0.52As is formed on the upper surface of a Fe-doped InP substrate 1.

Title: Method of measuring thin film thermal property value
Inventor: OKUDA SHINICHI
IPC: G01N25/18
Filed: 1991-02-28
Abstract: PURPOSE:To measure the thermal property values (heat conductivity, temperature conductivity, and heat capacity) of thin film material formed on a substrate without being affected by the substrate. CONSTITUTION:On a measured thin film 12 formed on a substrate 1, fine wires 2 with one terminals electrically connected together are arranged in parallel at narrower spaces than the thickness of the film. A current supplying probe 3 for a power source 5 is put in contact with the fine wires 2 for electrification and heating. The temperature change of the fine wires 2 is measured using a voltage measuring probe 4 as resistance change, and the temperature rise of the fine wires 2 and the lapse of time shown in logarithm are operated by a computer 7 and plotted in a graph. In accordance with the inclination of a graphic line for obtained temperature rise and a changing time for the inclination, thermal property values of the measured thin film are found.

Title: Process controller
Inventor: NAKAMURA MITSURU
IPC: G05B13/02
Filed: 1979-03-22
Abstract: PURPOSE: To exercise the best control under simple process control by performing control based upon a transfer function corresponding to a stable state as a system approximates a set value.  
     CONSTITUTION: A process controller, capable of coming into a stable control state in a short time, has main arithmetic part 2 and pre-processing part 3, which runs a program routine where a change in controlled variable c is supervised all the time since the beginning of actuation. Then, arithmetic based on the idle time data of control object 4 and the change degree of controlled variable C is carried out to predict a conrolled variable after the idle time. Further, a coincidence between this prdicted controlled variable and target value r is detected and manipulated variable C is decreased according to the detection value, thereby starting the control of main arithmetic part 2 by switching when the control object responds to a decrease in the manipulated variable. As a result, the control based upon a transfer function corresponding to its stable state is brought to effect as the system approximates a set value, so that the best control under simple process control can be exercised.

Title: Synchronizing control for image signal reproducing device
Inventor: KANEKO KIYOTAKA
IPC: G11B20/02
Filed: 1985-02-21
Abstract: PURPOSE:To stabilize a reproduced screen to prevent the oscillating frequency of the synchronizing circuit from pulling out by giving composite synchronous signals to the reproduced picture displaying device while synchronizing the composite synchronizing signals which consist of horizontal/vertical synchronizing signals and muting a reproducing video signal. CONSTITUTION:The multiple circuit sends a reproducing video signal S2 as it is or a multiple signal superimposed with a character signal to a television receiver. On the television receiver side, a vertical synchronizing signal S2a of the reproducing signal S2 outputted from the track Tj is given as the external synchronizing signal to the vertical deflecting circuit. This vertical synchronizing signal S2a is generated in delay of 7H against the PG pulse S3, and theoretically it is synchronized with the servo reference signal S13. So, even though there are any lag, the switch 31 is changed over to the terminal b side and pulled into the servo reference signal S13. Consequently, even when the external synchronizing signal is changed over from S14a to S2a, the oscillating frequency of the vertical deflecting circuit is kept in locking state as ever without pull-out. Thus it realizes a stable reproduced picture just after muting release.

Filed: 1991-03-01
Abstract: PURPOSE:To take a speedy countermeasure in case of fault by copying data in three-track units between a magnetic disk file group for backup acquisition and a magnetic disk file group or preliminary magnetic disk file group in a specific case. CONSTITUTION:In backup mode, a magnetic disk copy program 2-2 is read out of the magnetic disk file group 3 in, for example, three-track units and written in the magnetic disk file group 5 for backup acquisition. In case of data base fault, the magnetic disk copy program 2-3 copies data from the magnetic disk file group 5 for backup acquisition to the preliminary magnetic disk file group 4.

IPC: H01L21/027
Filed: 1981-03-13
Abstract: PURPOSE:To achieve a stable blanking performance in an electron beam drawing device by reducing charge-up of a blanking plate to contamination. CONSTITUTION:A repeller electrode is provided. With application of a repelling voltage on this electrode, attack of relfected electrons and secondary electrons on a means for deflecting electron beams is prevented.
