Title: Bar-shaped and planar luminous body by electric light emitting source
Inventor: SHINGU MASAKAZU
IPC: G09F13/22
Filed: 1993-05-26
Abstract: PURPOSE:To necessitate the smaller number of light sources than with the conventional system, to make the luminous body easily to view than the conventional assemblage by spots and to enable the production at a low cost by allowing the specific bar- and planar solid to emit light over the entire part by a high-luminance light emitting source. CONSTITUTION:A light emitting medium 2 belonging to an acrylic resin, glass or others is bored with a hole 3 to a tapered shape and ruggedness is formed on the inside surface thereof to make the inside surface translucent. The ruggedness absorbs light and emits light when the light emitting source 1 of the high luminance is cast thereto. The reason for forming the inside surface to the tapered shape lies in that the light has a rectilinearly advancing property and, therefore, that the entire part of the inside surface absorbs the light so as to make the light emitting medium 2 emit light from the entire part thereof. The entire part of the light emitting medium 2 acts as a uniform luminous body by forming such a shape. The large luminous body is produced with the fewer light emitting sources than the luminous body formed by using many light emitting sources and, therefore, the applications are widened to display plate, digital displays, illuminating indicator lamps, illuminations, accessories, etc.

Title: A/d converter for video signal
Inventor: MURATA NORIO
IPC: H04N7/00
Filed: 1989-06-28
Abstract: PURPOSE:To realize the low-cost A-D converter with high precision and a smooth A-D conversion characteristic by controlling the prescribed DC level of an input analog video signal or reference voltage so that the difference of the output values of both A-D converters comes to constant when the video signal of an overlap level is inputted. CONSTITUTION:The video signals of a boundary level between a high level and a low level which two A-D converters 104, 105 take charge of respectively are converted into digital signals by both the A-D converters 104, 105, and on the basis of a difference signal obtained by comparing this result, the DC voltage level of the input analog signal to be supplied to the A-D converters 104, 105 is controlled. When input analog signal voltage is below Ex+ /2, the A-D converter 105 outputs a digital value corresponding to this signal voltage, and besides, when it is over Ex+ /2, the A-D converter 104 outputs similarly the digital value corresponding to the signal voltage. The above-mentioned output of the A-D converter 104 is supplied to an adder 106, and here, an initial set digital value is added to it.

Abstract: PURPOSE: To obtain video images continuous in real time at a relatively high speed by selecting a gray level value so as to correspond to a change positioned between a prescribed first percentage and an actually obtained second percentage and clipping picture elements based on input gray level values intrinsic to the respective video images. CONSTITUTION: An input gray level for which an input picture element number provided with a highest gray level is 5% is defined as a gray level G5. In order to find a gray level value G0 to be obtained, gradient change between the gray level point of 4.5% picture element clipping and the gray level point of 4% picture element clipping is retrieved by every 0.5%, the gray level point G1 is decided as a clipping level value, a clipping gray level G0 is present between the gray level value G5 of 5% picture element clipping and the gray level value G1 of 1% picture element clipping and the gray level point GA positioned on a diagonal is decided based on the clipping gray level G0.  In the meantime, the clipping gray level point G8 on a low gray level side is also decided by considering a low luminance picture element group and retrieving the significant change of characteristic gradient between the 5% clipping and 1% clipping of the low luminance picture element group similarly to above-mentioned operations.
