Title: Manufacture of semiconductor device
Inventor: ITOU MITSUO
IPC: H01L29/72
Filed: 1978-03-29
Abstract: PURPOSE: To enhance the current amplification factor of the transistor and furthermore to lower the saturation voltage between the collector and emitter by doping the same conducting high-density impurity to the back of the single-conducting semiconductor substrate and then doping the impurity featuring the gettering function from the surface in a high density to condense the heavy metal contained in the substrate.  
     CONSTITUTION: P is deposited in a high density on both surfaces of P-type semiconductor substrate 1, and then the PSG film through the heat treatment. Then the PSG film is removed to form oxide film 3a of a fixed thickness. Film 3a only on the rear surface is removed using the hydrofluoric acid to from BSG layer 4 formed there. After this, the oxide film grown on layer 4 is removed, and B is diffused deep within substrate 1. At the same time, P which was diffused slightly when film 3a was formed is also diffused within substrate 1. Then film 3a and layer 4 are removed via the hydrofluoric acid, and then N + -type layer 6 and P + -type layer 5 are formed through the heat treatment. In this case, the heavy metal contained in B is collected within layer 6, and thus virtually no heavy metal goes into P - -type layer 1.

Title: Recording system and recording plus reproducing system for color video signal
Inventor: SHIRAISHI YUUMA
IPC: H04N9/86
Filed: 1980-03-21
Abstract: PURPOSE: To reduce the influence of crosstalk from adjacent tracks, by delaying only the chrominance signal to arrange horizontal synchronizing sections of chrominance signals in a line on adjacent tracks and not to arrange those of luminance signals in a line.  
     CONSTITUTION: The color video signal from terminal 1 is separated into the luminance signal and the chrominance signal, and they are inputted to low-pass filter 2 and band-pass filter 3, respectively. Variable delay circuit 21 gives a set delay time to the chrominance signal for every track to arrange respective horizontal synchronizing sections of delayed chrominance signals in a line on adjacent tracks on the recording medium. Recording positions of horizontal synchronizing signals included in luminance signals are not arranged in a line on adjacent tracks. Consequently, frequency-modulated luminance signals are not arranged in a line horizonally, and the tape pattern where only chrominance signals are arranged in a line horizontally is formed.

Filed: 1992-02-24
Abstract: PURPOSE:To obtain an inexpensive rubber compsn. excellent in chlorine water resistance by blending a blend rubber comprising an ethylene-propylene rubber or the same and a butyl rubber with a fine fluororesin powder. CONSTITUTION:A blend rubber comprising an ethylene-propylene rubber, or the ethylene-propylene rubber and a butyl rubber is blended with a fine fluororesin powder to obtain a chlorine-water-resistant rubber compsn. Since the conventional ethylene-propylene rubber is good but inferior in chlorine water resistance to fluororubbers, etc., members formed therefrom are gradually eroded when used in water service pipings for a long time to have problems such as softening, a decrease in strength and an increase in the percentage of permanent deformation, and are quickly eroded and deteriorated particularly when used in hot water service pipings because of contact thereof with high- temp. chlorine water to have a problem of short practical service life. The title rubber compsn., which have solved the problems of the prior art, is inexpensive and excellent in chlorine water resistance.

Abstract: PURPOSE:To remove a scattering in a combinational weight due to a change in a power supply by interrupting the current flowing in the electromagnets of feeders from a DC stabilized power supply by the same frequency as the intrinsic frequency of the feeders to drive the feeders. CONSTITUTION:When the electromagnets 301-30n of feeders 281-28n are provided with a driving current with the same frequency as the natural frequency of the feeders 281-28n, the feeders 281-28n largely vibrate in the direction H' of the magnetic field of the electromagnets 301-30n due to a resonance action and objects to be weighed supplied onto transfer tables 331-33n by a circular feeder 26 are supplied to intermediate hoppers 271-27n, respectively. Therefore, since the vibratory strength of the feeders 281-28n is stabilized and the stable supply of the objects to be weighed can be conducted, the scattering in a combinational weight relative to a set weight due to the change in a power supply is removed.

Title: Vertical semiconductor device
Inventor: SHIMAUCHI KAZUFUMI
IPC: H01L21/8234
Filed: 1994-03-08
Abstract: PURPOSE:To provide a power MOSFET wherein surge breakdown strength is large, current capacity increases and ON resistance can be made low. CONSTITUTION:A size of each cell is not uniform. As a cell comes near a gate unload electrode 7 from a source unload electrode 26, a size of a cell becomes larger, and a size of a cell changes so that a channel length is larger than the rate of enlargement of a channel width. With the increase of a cell size, an 10 current becomes harder to flow; however, a cell far from a gate unload electrode is late in turning 'on' due to voltage drop when compared to a cell near a gate unload electrode. Turning 'on' of each cell can be made further uniform by making an ID current easy to flow due to the late turning 'on' by voltage drop.
