Title: Semiconductor device
Inventor: SHIRAI KOJI
IPC: H01L21/336
Filed: 1990-10-17
Abstract: PURPOSE:To alleviate a limit of a responding speed, to reduce an ON resistance and to improve a current driving capacity by optimizing an electric field distribution in a MOSFET to enhance its withstand voltage, and shortening a distance between a source and a drain to be miniaturized. CONSTITUTION:The thickness of a gate insulating film 14 of a MOSFET is gradually reduced in an impurity concentration in the order of channel regions 13 (131, 132, 133, 134) sequentially existing from the region 131 toward the region 13 at a source side. That is, an electric field distribution is so optimized that the distribution of the thickness of the film 14 and the distribution of the impurity concentration of the region 13 are controlled to make an electric field in the MOSFET uniform. Thus, reliability of the film 14 at a drain side is obtained, a threshold value voltage is reduced, and its electric withstand voltage can be improved. Since a distance between the source and the drain is shortened to be miniaturized, a switching speed is improved by reducing the thickness of the film 14 as an average, its ON resistance is reduced, and a current driving capacity can easily be improved.

IPC: F23N5/00
Filed: 1988-11-08
Abstract: PURPOSE:To quickly and accurately discover an abnormal burner by finding the difference value between a real flow change accompanied by the addition of a burner at standard fuel pressure and a set flow per burner to indicate in the above device such as a thermal power boiler. CONSTITUTION:The signal of a real flow fn+1 at the time when the signal of the real flow fn to n normal burners operated at the standard fuel pressure P0 of a fuel supply pipe and a burner unclear of the presence or absence of abnormality is added and operated is input in a first computing element R1 to calculate the difference value between both the flows and change to the flow of the added burner so as to transmit to a second computing element R2. The second computing element R2 finds the difference value with the set flow f0 per normal burner at the standard fuel pressure P0. The second computing element R2 can judge that it is normal in the case where (fn-fn+1)-f0 is equal to zero, it is clogging in the case where the above formula is less than zero, and it is abrasive in the case where the above formula is more than zero. The difference in value is indicated in a display DP. As described above, the abnormal burner can quickly and accurately be discovered.

Title: Capsule screening system
Inventor: ABE HIROHISA
IPC: C12N5/10
Filed: 1991-09-30
Abstract: PURPOSE:To perform the title screening automatically by measuring the fluores cence intensity, etc., of planarly arranged capsules and by fitting the tip of a freely movable manipulator with a pipette followed by moving it to the aimed capsule. CONSTITUTION:The absorbance or fluorescence intensity of each of planarly arranged capsules is determined to search such capsules with the characteristic value at or higher than a specified level. The tip of a manipulator movable in the x, y and z directions is then fitted with a pipette, and its tip is made to move to the aimed capsule position. A water or air jet from the pipette is allowed to impinge on the capsules to separate them from the other ones through the meshes in a capsule-holding vessel; alternately, the aimed capsules are put to suction with the pipette and separated from the others. Thereby, only the capsules with fluorescence intensity at or higher than a specified value can be collected.

Title: Method for preventing crystallization of chunky graphite in spheroidal graphite cast iron
Inventor: ITOFUJI HARUKI
IPC: B22D1/00
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To obtain a large-size, thick-walled spheroidal graphite cast iron free from formation of chunky graphite by performing spheroidizing treatment by the use of an Mg spheroidizing material completely free from rare earth elements and further performing inoculation treatment by the use of an inoculate completely free from rare earth elements. SOLUTION: A large-size, thick-walled spheroidal graphite cast iron, having >=80mm wall thickness or >=4cm modulus M, is produced. The crystallization of chunky graphite is mainly caused by REM. The purpose of the use of REM is (1) to compensate spheroidizing-inhibiting elements, (2) to inhibit the fading of Mg, (3) to increase the number of graphite grains, and (4) to inhibit Mg reaction by being added to an Mg type spheroidizing material. However, the purpose (1) is unnecessary because high purity scrap becomes easily obtainable and the precision of equipment for analysis is increased. Further, the purposes (2), (4) are unnecessary because spheroidizing temp. for the large-size, thick-walled spheroidal graphite cast iron is low and, as a result, the proceeding rate of fading is retarded and Mg reaction does not occur.  Moreover, the purpose (3) is also unnecessary because the increase in the number of graphite grains is a problem in the case of a thick-walled product.

Title: Picture signal communication device/method
Inventor: MAEDA MASAMINE
IPC: H04J13/00
Filed: 1996-10-23
Abstract: PROBLEM TO BE SOLVED: To prevent an expanded picture from becoming unnatural on a reception side by substituting the error of control data controlling the compressed picture data amount of a picture signal with data generated by means of using plural pieces of other control data when it is detected. SOLUTION: The occurrence of the error during transmission is discriminated by an error correction circuit 205 in transmitted compressed picture data and that in which data the error occurs is sent to a microcomputer 206 as a data status. When the error is in the data status, the scaling factor value of compressed picture data immediately before of compressed picture data which is processed at present, for example, is selected to be used for the scaling factor value. The selected value does not completely match with the value where the error occurs. In the case of a moving picture obtained by taking a regular object, a possibility that an extreme change occurs is low as the picture between fields and a possibility that the scaling factor value similarly changes becomes low.  Thus, the picture is prevented from being unnaturally reproduced even if an expansion processing is executed by using the value.

Filed: 1994-11-16
Abstract: PURPOSE: To realize the highly precise and high-speed grid plotting. CONSTITUTION: At the time of plotting the grid, after selecting Y-coordinate related to the plotting, an element pattern is plotted at both the ends of a straight line corresponding to this Y-coordinate (a). In the case where an interval between both the ends is divided into an odd number of pieces by the grid, the element pattern is plotted at a grid point neighboring to the end point of one side (b). In the case of an even number, the middle point is determined, and the element pattern is plotted (c). By repeating this procedure, the plotting can be executed in an X-direction highly precisely and at high speed. By repeating the similar procedure in respect of a Y-direction as well, the grid can be plotted highly precisely and at high speed.
