Title: Video signal processor
Inventor: YAMASHITA HARUO
IPC: H04N9/68
Filed: 1984-07-10
Abstract: PURPOSE:To obtain a picture with high contrast without unbalancing color balance by detecting a peak of a maximum value of an RGB video signal and multiplying an amplitude coefficient obtained from the said peak data and a reference amplitude with a video image data subject to A/D conversion at a gain control section. CONSTITUTION:A peak output (j) of a maximum value signal (f) of RGB video signals f, g, h is obtained by a maximum value detecting circuit 4 and a peak detection circuit 5. A divider 13 divides a reference amplitude data (l) by using a data (k) obtained from the output (j) subject to A/D conversion and obtains an amplitude coefficient (m). The output (r) of the signal (f) is expressed as r=l. f/j. Since the maximum amplitude of the (f) is equal to the (j), the maximum value of the (r) is equal to the reference amplitude data (l), and the gain adjustment is conducted accurately. Since the same coefficient (m) is multiplied with the other signals g, h the gain is adjusted without unbalancing the RGB.

IPC: H04N5/93
Filed: 1994-06-24
Abstract: PURPOSE:To allow the noise reduction circuit employing a 1H delay element to reduce the deterioration in vertical resolution while reducing sufficiently noise at a low frequency band. CONSTITUTION:A non-correlation detection circuit 4 and a non-correlation control circuit 5 detect a non-correlation part of a signal obtained by subtracting input and output signals of a 1H delay element 2 at a subtractor circuit 3. The attenuation to attenuate the noise component including the signal of the non-correlation part from the input signal in a small amplitude signal being a noise component is increased by adjusting a level adjustment circuit 7 depending on a signal level of the non-correlation part and the noise component is reduced for all bands from a low frequency band to a high frequency band. On the other hand, since the attenuation to attenuate the noise component including the signal of the non-correlation part from the input signal is decreased for the non-correlation part of a large amplitude signal at a low frequency band where deterioration in vertical resolution is remarkable, the deterioration in the vertical resolution is reduced.

Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To make the whole of an electromagnetic contactor small and compact by enhancing the space efficiency of a case by somewhat altering the outline and shape of the case to change the disposition of return springs. SOLUTION: In this electromagnetic contactor, a switching contact assembly and a flat plate-shaped electromagnet 6 are incorporated one above the other into a box-shaped case 1, and return springs 10 or compression coil springs for pressing up a movable-contact support frame are disposed at diagonal corner parts in the case and by the side of the electromagnet. Spring accommodating parts 13 for accommodating the return springs are formed at peripheral corner parts of an upper case 1b by rounding the outline thereof outward of the case.  Because this structure allows the return springs to be disposed in the spring accommodating parts formed at the corner parts of the case outwardly biased from the side of the electromagnet, the space for installing the electromagnet is accordingly increased to allow the area of a magnetic pole plate to be enlarged, based on which the number of turns of an electromagnetic coil and hence the height thereof are reduced and the sheet thickness of a movable magnetic core are reduced as well, in turn contributing to the entire height reduction of the electromagnetic contactor.

Abstract: PURPOSE:To enhance workability and to easily decorate a fine object to be decorated by forming the contour of a coloring region using silicone oxidized and cured by oxygen in air. CONSTITUTION:After a drawing object (e.g., leaf) is pressed to the surface of a clay plate, baking is performed to obtain an unglazed plate 11 having the shape of the leaf pressed to the clay plate remaining thereon as a recessed part 13 even after baking. A part of the recessed part 13 to which the petiole of the leaf is transferred is set to a coloring region 15 and a part where the leaf is not pressed is set to a non-coloring region 17. Silicone is applied to the surface of the non-coloring region 17, for example, by using a paintbrush so as to form contours 19a, 19b to the boundary part of the coloring region 15 and the non-coloring region 17. Thereafter, the coated silicone is cured by air oxidation to form a protective film 21. Next, glaze 23 is applied to the coloring region 15, for example, by using a paintbrush to color said region 15. Continuously, the coated glaze 23 is dried and the protective film 21 is subsequently peeled off. By this method, the glaze 23 can be applied only to the coloring region 15 using the contours 19a, 19b as boundary parts.

Filed: 1977-11-30
Abstract: PURPOSE: To provide a descharge lamp which has a high binding strength of electron emitting substance and can have its starting voltage reduced and its light flux maintaining ratio heightened by keeping the electron emitting performance high.  
     CONSTITUTION: A pair of electrodes 4 and an auxiliary electrode 41 are provided at sealed parts 3 on both the ends of a tube 2 made of quartz glass. Each of the electrodes 4 is made by providing an electrode coil of high melting point metal around an electrode shaft 7 and providing an electron emitting substance layer 9 between the shaft 7 and the coil 8. The layer 9 contains tungstate. The tungsten content percentage is gradually reduced toward the external surface of the layer 9. Since the tungstate serves as aggregate, the binding strength of the electron emitting substance is heightened. Because the percentage of the electron emitting substance is gradually raised toward the external surface of the layer 9, the electron emitting performance is kept high. As a result, the starting voltage can be reduced and the light flux maintaining ratio can be heightened.

Abstract: PURPOSE:To obtain a copy in an optional size, by operating means, which scan an object to be copied to change the optical path length and move a photoreceptor, independently of one another. CONSTITUTION:Since the copying magnification in the direction vertical to the scanning direction is determined by a ratio of optical path lengths, the motor which drives a lens 7 and mirrors 5 and 6 is driven to move a lens block and a carriage so that the ratio of the optical path length between an original A and the lens 7 to that between the lens 7 and a photoreceptor 9 becomes a designated magnification. Since the magnification in the scanning direction is determined by a ratio of speeds, the motor which moves an exposure lamp 3 and a mirror 4 and a drum driving motor are so driven that the ratio of the speed of a scanning body to that of the photoreceptor becomes a designated magnification. Sonsequently, the ratio of speeds and the ratio of optical path lengths are varied easily by individual motors, and the copy in an optional size is obtained in accordance with the desire of the user and the size of a form.
