Title: Data processor
Inventor: KATSUHARA JIROU
IPC: G06F7/02
Filed: 1981-11-06
Abstract: PURPOSE:To reduce the load with simple constitution for a data processor which is suited to obtain the maximum or minimum value, by comparing the output digital value of an A/D converting circuit with the input digital value of a D/A converting circuit. CONSTITUTION:A digital input 2 which is fed in time division is converted into an analog quantity and then into the digital value to be held by an A/D converting circuit 4. The output digital value of the circuit 4 is compared with the digital value of the data to be fed through a comparator 5. The comparator 5 receives the timing signal 6 from an arithmetic processing part 1' and performs comparison. While the circuit 4 works by receiving a converting command produced with the pulse signal 7 supplied from the comparator 5 as well as the timing signal 8 from the part 1'. Then the maximum or minimum value is obtained for the digital signal 2 which is fed in time division.

Title: Method of adjusting clean space flow and clean space forminginstrument
Inventor: TSUINON DOBURISU
IPC: A61G10/00
Filed: 1985-08-16
Abstract: A selected part of or the entire body of a patient on an operating table can be insulated from air in the surrounding atmosphere by a stream of clean-room air which issues from a distributor head and is caused to form a relatively thin layer between the selected part and the surrounding atmosphere. Such relatively thin layer can be established and maintained by heating or cooling the stream so that its temperature deviates from that of air in the surrounding atmosphere by a few degrees centigrade. The direction of flow of a portion of or the entire stream can be changed by one or more secondary streams. The moisture content of the stream of clean-room air can be increased by causing it to flow through a steam chamber. Heating or cooling of the stream can precede or follow sterilization of atmospheric air which is to form the stream.

Title: Wafer test method
Inventor: NISHIMURA KAZUHIRO
IPC: G01R31/26
Filed: 1990-07-05
Abstract: PURPOSE:To shorten the measuring time of one semiconductor wafer as a whole by a method wherein measuring items on an electrical characteristic are changed depending on where a semiconductor element as an object to be measured is situated with reference to a prescribed reference point on a semiconductor wafer. CONSTITUTION:The central point P of a semiconductor wafer 1 is used as a reference point. Measuring items on an electrical characteristic are changed depending on where semiconductor elements 2 are situated on the inside or on the outside of a circle C whose radius from the reference point P is R as shown by a broken line in the figure. At this time, the radius R is set to an optimum value which is obtained statistically. When the test operation of an element 2 is started, it is judged, on the basis of the detection data of a sensor, whether the semiconductor element 2 to be measured is situated on the inside of the circle C or not. When it is judged that the element is situated on the outside of the circle C, the measuring operation of all measuring items, e.g. No.1 to No.30, is executed. When it is judged that the element is situated on the inside of the circle C, the measuring operation of only measuring items No.1 to No.15 by which the probability to cause a defect is higher than that of measuring items No.16 to No.30 is executed.

Abstract: PURPOSE:To automate the manufacturing process of a commutator by integrally forming a commutator member and resistive resin by pressing the resin against the inner peripheral surface of the end section provided with a plurality of click sections of the commutator member made of a conductive material. CONSTITUTION:The top and bottom molds 15a and 15b of a metallic mold are respectively pressed against both ends of a cavity 13 into which a primary molded member 14 is inserted. As a result, a nearly annular space 16 is formed between a projecting section 2b and small-diameter cylindrical section 3b.

Title: Method for controlling laser welding device and welding state, and manufacture of center electrode for spark plug
Inventor: MUSASA MAMORU
IPC: B23K26/03
Filed: 1994-07-08
Abstract: PURPOSE:To reduce the frequency of a sampling inspection by picking up plasma generating from an object to be irradiated, measuring the area or the height of a picture, comparing a measured value with an allowable value, and judging the acceptable or the nonacceptable of the object. CONSTITUTION:An object (b) to be irradiated is irradiated by a laser beam 6 outputted from a laser oscillator 1. When the object (b) is irradiated by the laser beam 6, plasma 7 is generated on the surface of the object (b). The only plasma 7 is picked up by an image pickup mechanism 31, and the area of the picture of the picked-up plasma 7 is calculated by a picture processing mechanism 33. The area of the picture of the plasma 7 is changed by the intensity of the energy of the laser beam. And, the acceptable or the nonacceptable of the welding is judged by comparing an allowable value with a measured result by an acceptable and nonacceptable judging mechanism. Consequently, the frequency of a sampling inspection performed frequently can be reduced and a man-hour is reduced.

Filed: 1992-07-08
Abstract: PURPOSE:To reduce a jam generation rate by selecting a tray provided in a recording device. CONSTITUTION:In a recording device 13, the number of paper sheets fed out from a first to third paper feed trays 141-143 as well as a jam generating frequency is counted, and a jam generation frequency of each of the first to third paper feed trays 141-143 is calculated based on these count values. Priority of selection is lowered for a paper feed tray whose calculated result is not less than a specified value, while tray selection is conducted with a predetermined priority for a paper feed tray whose result is less than a reference value. Since the tray whose jam generation frequency is low is preferentially used, the jam generation is suppressed at a low value.
