Title: Detector for infrared ray
Inventor: MIYAMOTO YOSHIHIRO
IPC: H01L31/10
Filed: 1980-12-24
Abstract: PURPOSE:To obtain sensitivity high enough to detect infrared radiation of long wavelength and reduce the noise by a method wherein the forbidden band width of a surface region is made wider than that of a bulk region including a P-N junction. CONSTITUTION:A compound semiconductor layer 2 which is approximately 2,000Angstrom   thick and has a wide forbidden band is formed on a semiconductor substrate 2 which  has a narrow forbidden band and is covered by an insulating film 3 of approximately  5,000Angstrom thickness and an aperture W is made. An impurity diffused layer 10 of approximately 5,000Angstrom  thickness and an aperture W is made. An impurity diffused layer  10 of approximately 5,000 deg.C depth is formed and is covered by an insulating thin film  7 and an aperture 5 is made and a wiring 6 is formed. As the forbidden band width is widen in the completed infrared detector region 8, the generation-recombination current  in the surface region is small and reverse direction characteristics are improved. On  the other hand, the incident light passes through the insulating film 7 and the semiconductor layer 2 with the wide forbidden band width and carriers are generated in a  depletion layer produced near the bottom 4 of the layer 10, so that the sensitivity in  the aimed long wave length band is improved. As the generation-recombination current is small, little noise is produced. And the output impedance is high enough to  obtain high efficiency.

IPC: H03K5/1252
Filed: 1982-10-22
Abstract: PURPOSE:To eliminate noises out of a periodic pulse signal by forming a gate pulse with a pulse signal having a fixed cycle. CONSTITUTION:A signal (a) having a cycle T and pulse width t1 is supplied to a terminal 1. A 1-shot multi-vibrator MM3 is triggered with the rise of the signal (a) and produces a pulse signal t3 having the width slightly smaller than time (T-t1). An MM5 is triggered with the rise of the signal (a) and produces a pulse signal t4 having the width slightly smaller than the time t1. The noises within tie (T-t1) of the signal (a) are eliminated with the output pulse signal of the MM3 by opening and closing a gate 4. At the same time, the noises within time t1 of the signal (a) are eliminated with the output signal of the MM5 by opening and closing a gate 6. In such a way, it is possible to eliminate noises with no deterioration of the phase of the signal (a).

Abstract: PURPOSE:To obtain a copying machine which is easy to operate to satisfactorily reproduces color by constituting in such a manner that at least a part of a reflecting mirror can freely move, and changing a quantity of light which irradiates a copying original surface. CONSTITUTION:An original 20 on a glass platen 4 is exposed by a width 2h by means of a lamp 16 and circular, elliptic, or parabolic reflecting mirrors 17a and 17b both of which are rotatable engaged with shafts 21a and 21b respectively, at their one end. The distribution of a quantity of light is almost concentrated in the width 2h. When the reflecting mirrors 17a and 17b are opened around corresponding shafts 21a and 21b, the distribution of the quantity of light on the surface of the original 20 varies, and the quantity of light in the width 2h is reduced; consequently the quantity that the light reaches the photosensitive member is reduced. Therefore, this provides the copying machine which changes a quantity of light which irradiates a copying original surface and which satisfactorily reproduces color when enlargement of reduction copying is carried out, or when various densities is adjusted, by changing the positional relation between the reflecting mirrors and the light source; the need for alternations in sensitivity of the photosensitive member and light emission characteris tic of the lamp is eliminated; also the need for alternations in diaphragm, variable density filter and speed at which the photosensitive member is moved is eliminated.

Title: Burner device
Inventor: MASAI TADAHISA
IPC: F23C5/08
Filed: 1982-10-25
Abstract: PURPOSE:To further reduce production of NOX without an increase in production of smoke dust in combustion gas, by a method wherein plural burners at each stage are structured so that the amounts of fuel injected on both sides of a fuel injection nozzle are different from each other, but the nozzle may form a fuel injection flow in which its projection injecting direction extends on an appropriately indentical line, and are disposed so that fuel projection injecting direction alternately extends horizontally and/or vertically. CONSTITUTION:The burners at each stage of lower stage burners 30 and middle stage burners 40 form a pair of fuel injection flows extending in the reverse direction to each other within a projection surface centering around a fuel injection nozzle. The flows 14 of the fuel injected through a burner 30B at the lower stage of a second row and through a burner 30E at the lower stage of a fifth row equalize in the amount of fuel injected, and in relation to the burners on stages except the above, the amounts of fuel injected therethrough are different from each other. Meanwhile, all the upper stage burners 50 are structured so that a large amount of fuel is uniformly injected. This prevents production of a unburnt content due to flame interference, suppresses excessive production of the unburnt content at a part, by which radiation cooling is caused, and permits appropriate suppression of production of NOX at a high temperature part.
