Inventor: KIMURA MASAKI
IPC: H01L21/20
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To provide a thin film epitaxial wafer under the reduced pressure which improves electrical characteristic and manufacturing yield, and a method of manufacturing the same. SOLUTION: A single crystal silicon substrate where COP(Crystal Originated Particle) does not exist or a small number of COP exists is manufactured, and a thin epitaxial layer (4.0μm or less) is formed under the reduced pressure to this single crystal silicon substrate by the epitaxial growth method. As the method of manufacturing single crystal substrate, high concentration P type impurity is added. Thereby, after manufacture of the thin film epitaxial wafer, COP on the epitaxial layer surface is eliminated or reduced. Therefore, defects of a single crystal substratre due to COP is eliminated or reduced to improve electrical characteristic of the thin film epitaxial wafer and manufacturing yield.

IPC: H05K3/00
Filed: 1992-02-13
Abstract: PURPOSE:To detect only defects in a pattern without being influenced by dispersion of the pattern edge by finding the minimum value while shifting the sum total of absolute values obtained on a specific picture element from a difference image until it comes to the maximum bit number. CONSTITUTION:A rough positioning circuit 6 compares an input digital image signal 5 with a memory image signal 8 read from an image memory circuit 7, and carries out a rough positional correction of the signal 5. A difference image calculating circuit 10 takes out an already designated NXN picture element signal from an already corrected digital image signal 9, and finds an inter-image difference between the signal and a NXN picture element signal taken out from the signal 8 while shifting the signal a single picture element by a single picture element in the horizontal/vertical directions to the already designated maximum picture element number M. An adding circuit 12 finds the sum total of absolute values of difference image signals 11, and a minimum value detecting circuit 14 shifts the sum total until it comes to the maximum picture element number M, and finds a value where a value of a sum total signal 13 becomes minimum. A defect detecting circuit 16 takes out a value as a defect when a minimum value detecting signal 15 from the circuit 14 is equal to or larger than a constant value.

Title: Recording and reproducing system for color video signal
Inventor: KANAMARU HITOSHI
IPC: H04N9/82
Filed: 1987-02-06
Abstract: PURPOSE:To continuously obtain reproduced picture by means of wide-band color signals for a long time by reading respective recording information on the main surfaces of first-third recording medium and reading respective recording information on the main surface of a fourth recording medium and other main surfaces of the first and the second recording medium at the time of reproducing. CONSTITUTION:At the time of reproducing, respective recording information on the main surfaces of the first and the third recording media are read, and respective recording information on the main surface of the fourth recording medium and other surfaces of the first and the second recording media are read. Since wide-band three primary color signals are reproduced from obtained three synthesizing color signals, the wide-band color video signals of 20MHz can be recorded and reproduced without executing band-compression such as MUSE (Multiple Sub-Nyquist Sampling Encoding) system, and the reproduced picture of high resolution can be obtained irrespective of the moving image or the still image. Since three synthesizing color video signals are prevented from being recorded on two recording surfaces of the same disk, the reproduced picture by the wide-band color video signals can continuously be obtained by plural screen disk players for a long time.

Abstract: PURPOSE:To reduce the idle space generating between adjacent conducttors or between the conductors and the bobbin and the like, and to improve the space factor of the conductors by a method wherein the shifting position of a flat type wire is limited within the specific region located along the circumferential direction of the bobbin. CONSTITUTION:In the winding of the first layer, a flat type wire Y is shifted by the amount of wire width on the winding surface IV up to the third row, and as the winding of the fourth row is finished just before the winding surface IV, the number of turns per layer becomes 15/4. The idle space generated in this case becomes a triangle DA'E' and another triangle PQ'T. In the winding of the second layer, shifting is conducted in a winding surface III up to the third row, and winding is finished just before the winding surface III in the fourth row; to be more precise, the winding is finished at a segment CG. The shifting is conducted on the winding surface II on the third layer and the shifting is conducted on the winding surface I on the fourth layer respectively in the same manner as above, and the winding of the four layers in fourth row is finished. To be more precise, as a fraction of 1/4 each of the entire circumference is generated against the number of turns per layer, the surface on which shifting is conducted is moved by one surface at a time. Also no gap is present between the flat type wires Y.
