Title: Information processor
Inventor: KUNIMATSU ATSUSHI
IPC: G09G5/36
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To attain the high graphic drawing performance and the high cost performance in an entire system by preparing a preprocessing part at a coordinate conversion processing part to calculate the parameter that is given to a drawing processing part. SOLUTION: A CPU 3 includes a preprocessing part 13 and a main processing part 15. The part 13 calculates the initial value of DDA of the main processing, etc., and is mounted on a processor 1 not on the CPU 3. Thus, the I/F bus band width can be increased between a coordinate conversion unit 19 of the processor 1 and a main bus 7. Then, a processor core 17 has no overhead to produce a CPU command, so that the system performance is improved. In addition, the overall system cost performance is improved since the part 13 is prepared at the processor 1 despite the difference of process features recognized between the processor 1 and the CPU 3.

Title: Terminal for counter measure against unwanted radiation
Inventor: MINAMI KAZUYA
IPC: H01R4/64
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To provide a terminal for counter measure against unwanted radiation which is used in a liquid crystal display by arranging a movable part containing a bending part bending in a first bend radius upward from a bottom part and a part curving in the inverse direction of the bending part in a bend radius larger than the first bend radius on its rear side. SOLUTION: A terminal for counter measure against unwanted radiation is composed of a fixing surface 1a part with a circuit board, a sparingly 1b part, an attracting surface 1c part in an automatic machine and an 1d part of a part to prevent an overlap of mutual terminals. The 1d part prevents a condition where mutual terminals frequency overlap each other or the terminals are deformed or a great loss is caused in its processing when the terminal 1 for an unnecessary radiation measure is taken out of a metal mold and is sent to the next plating process, when this terminal is juxtaposed in a cassette and is sent or this terminal 1 is juxtaposed, arranged and is made to stand by in a terminal housing part of the automatic machine. The 1e part is set so that the 1d can jump away, and impairment of springiness of the terminal for an unnecessary radiation measure is prevented.

Title: Impact type granule flowmeter
Inventor: ISHIWATA NARIMITSU
IPC: G01G11/00
Filed: 1984-02-07
Abstract: PURPOSE:To perform measurement highly accurately without the effect of the natural frequency of a detecting shaft, by making the shape of the cross section of the detecting shaft a rectangular shape so that the vertical side surface is longer than the horizontal surface, and sticking strain gages at two positions on the vertical side surfaces of the detecting shaft. CONSTITUTION:A detecting shaft 9 is fixed to a bracket 8. A detecting plate 10 is attached to the end part of the detecting shaft 9 in a slanted state. The shape of the cross section of the detecting shaft 9 is rectangle. The length H of one side of the vertical side surface is lower than the length W of one side of the vertical side surface. Pairs of strain gages 11a, 11b, 12a, 12b, 13a, 13b, 14a and 14b are stuck to the front and back sides of point P1 and P2, which are separated by a specified distance in the vertical direction, on the vertical side surface 9a and 9b of the detecting shaft 9. Since the cross section of the detecting shaft 9 has the above described shape, the section modulus of the detecting shaft in the vertical direction is large and that in the horizontal direction is small. Therefore, bending action in the vertical direction can be neglected. Even though the detecting shaft 9 is vibrated at a natural frequency, it is synchronized. When the difference between the signals is eliminated, highly accurate measurement can be performed without the effect of the vibration.
