Title: Control method for image quality using result of movement presumption
Inventor: NAGAMOTO AKIRA
IPC: H04N19/137
Filed: 1995-02-06
Abstract: PURPOSE: To perform control that is suitable for MPEG coding by utilizing information that is acquired before encoding video and detecting scene changes. CONSTITUTION: After a motion compensating 1 performs motion compensation of an input signal from a reference image, and a discrete cosine transforming part 2 transforms it. It is quantized by a quantizing part 3, and its result is encoded by a variable length coding part 4 and transmitted. An encoded image is processed by an inverse quantizing part 5 and an inverse discrete cosine transforming part 6 and stored in frame memory 7 to make it the next reference image. A motion estimating part 8 performs motion estimation before this process for motion compensation. Scene change information is extracted from the motion estimation and is utilized for image encoding. Motion estimation is always performed before encoding video. Therefore, excessive calculation is hardly needed, with excellent detection performance.

Title: Semiconductor device
Inventor: ISHIDA JUNICHI
IPC: H01L29/861
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To accomplish a small loss, a high speed, and a soft recovery characteristic in a device and apply such a device to a high frequency switching circuit, etc., by adding arsenic as an impurity into a second semiconductor region and specifying an interlattice oxygen density. SOLUTION: As a structure of a diode, an N type conductive layer 2 of a low impurity density including phosphorus is epitaxially grown on a semiconductor substrate 1 including arsenic and then boron, etc., is diffused in the N type conducive layer 2 to form a P type conductive layer 3 of a high impurity density. The N type conductive layer 2 and the P type conductive layer 3 form a PN junction J. In the substrate 1, the N type conductive layer, and the P type conductive layer 3, platinum is diffused. With an arsenic subwafer, therefore, the lower an interlattice oxygen density is, the more stabilized characteristic is obtained after diffusion of platinum. Especially, trade-offs between the forward voltage VF and a reverse recovery time trt is small and a small loss and a soft recovery characteristic can be easily accomplished.  If an allowable critical value of the interlattice oxygen density is 1.5×1018/cm3 or below, a characteristic can be stabilized and an yield can be increased.

Title: Joint structure of exterior face
Inventor: MIYAJI KYOICHI
IPC: E04F19/02
Filed: 1989-01-27
Abstract: PURPOSE:To improve the fireproofing performance of an exterior face by pressing dry joint material into a jointing gap of an exterior material to fill up the jointing gap, and thereby flowing out non-combustible sealing material from a sealing material filling portion into a concave groove. CONSTITUTION:Dry jointing material A is inserted from a sealing material filling portion 8 into a jointing gap 5, and the sealing material filling portion 8 is then pressed into a concave groove 2, and a jointing material main body 7 is concurrently pressed into the jointing gap 5. When the sealing material filling portion 8 has been pressed into the concave groove 2, the sealing portion 8 undergoes external force to elastically deform, and non-combustible sealing material 9 flows out from a flowing out gap 10 to fill up the concave groove 2. Thus, even when a fire breaks out, since the non-combustible sealing material 9 has filled up the concave groove 2 wider than the jointing gap 5, flames can not enter a house, and its fireproofing performance can be therefore improved.

Title: Electric cooker
Inventor: OKABE YOSHIYUKI
IPC: F24C7/02
Filed: 1984-02-03
Abstract: PURPOSE:To obtain uniform scorched color of bread regardless of the number of pieces of bread to be toasted, by constituting an electric cooker such as an oven toaster in such a manner that the toasting time in accordance with the number of material to be cooked can be set by a signal which is outputted from a sensor device, sensing the number of material to be cooked, placed on a wire net rack in a heating chamber of an oven toaster or the like. CONSTITUTION:For example, when two pieces of bread are put on a net rack 3, the bread actuates a sensing lever 4 to lower it down. The net rack 3 is moved into a heating chamber by the closing action of a door. Then the lowered free end of a lever 4 contacts to the tip of the lever 6 of a sensing switch 5, closing the contact points of a switch 5. Then the toasting time for two pieces of bread is set in an electronic timer. When one piece of bread is toasted, the bread is to be placed in the position of a rack where the lever 4 cannot be actuated by the bread. As the lever 4 cannot work because it is not actuated by bread, the contact points of a switch 5 remain open and the toasting time for one piece of bread is set in a toaster. By this structure, uniform brown scorched color can be obtained on bread, regardless of the number of pieces of bread to be toasted.

IPC: G11C16/06
Filed: 1992-02-04
Abstract: PURPOSE:To perform stable read-out by comparing potential of two dummy bit lines with potential of a bit line, in all combinations of two dummy bit lines whose set values of mutual conductance are close each other. CONSTITUTION:A column selecting circuit 2 connects a bit line B1 to a data line D, while a charging circuit 3 previously charges the line D and the line B1 at potential of V0 by making a CP signal activated state. If the transistor 11 of a memory 1 is set to a prescribed threshold value, a reference voltage VRFF2 is neglected and a comparison result SA1 is outputted by comparing with a reference voltage VRFF1 in a first comparator 5. The reference voltage VRFF2 is neglected and a comparison result SA2 is outputted by only comparing with a reference voltage VRFF3 in a second comparator 6 too. Therefore, since these potential differences in comparison have the range more than the least set pitch among threshold values of at least three kinds, the comparison margin can be enlarged, and stable read-out can be performed.

Filed: 1981-02-09
Abstract: PURPOSE:To improve the precision of a stop position and to shorten the access time, by controlling a tracking means to be active or inactive and operating a timing on a basis of a target address and the current address. CONSTITUTION:During the high-speed movement, a switch 36 is turned off, and a tracking control is made inactive. Therefore, the position of a light spot coincides with a representative position of an information reading means 20, and the current address which is read at that time indicates the position of the information reading means accurately approximately. When the read current address is within a constant range (r) of the address of a target track, a time when the information reading means 20 is damped is determined on a basis of the target address and the current address, and at this time, applying the high-speed movement signal to a motor driving circuit 32 is stoped. When the information reading means 20 stops, the switch 36 is turned on again to reach the target track where the tracking control is restarted.

Abstract: PROBLEM TO BE SOLVED: To remove the influence of a flicker by a method wherein a light shielding operation is performed, at arbitrary intervals, between a liquid-crystal display device and a device which takes into a display image. SOLUTION: Light from a backlight 3 is transmitted through a liquid-crystal panel 2 as an object to be inspected, it is taken into a camera 1 at constant intervals via a liquid-crystal shutter 5, it is analyzed by an image processor 4, and a display flaw is detected.
