Filed: 1982-03-31
Abstract: PURPOSE:To reduce considerably the number of gate or element per a stage, by constituting a unit stage with a bistable circuit and the first and the second coincidence gates which distribute a trigger pulse to the bistable circuit. CONSTITUTION:A unit stage 200 is constituted with bistable circuits 23 and 24 and the first and the second coincidence gates 21 and 22 which distribute the trigger pulse to bistable circuits 23 and 24 (other unit stages 100, 300, and 400 have the same basic constitution); and all unit stages 100, 200, 300 and 400 are reset by a preliminary resetting means R once just before the timing of a preset P, thereafter, a set signal is supplied to the unit stage to be set by selective setting means 17, 26, 36, and 46. Thus, the conventional function is obtained with the number of gates or elements smaller than that of the conventional constitution.

Title: Liquid leakage detecting method
Inventor: NUKUI KAZUMITSU
IPC: G01M3/02
Filed: 1987-03-10
Abstract: PURPOSE:To easily specify the leak place of liquid by monitoring an object monitor area by an infrared camera and making the variation position of its infrared-ray radiation distribution correspond to the position of an object image corresponding to a visible image. CONSTITUTION:The monitor area 2 including piping 1 to be monitored is monitored by the infrared camera 3. The signal of the camera 3 is processed by an infrared-ray radiation temperature processing part 41 and an object image (piping image) processing part 42 respectively. A variation detection part 43 compares temperature distribution images obtained by the temperature processing part 41 at different times and when variation at leak liquid temperature is detected, both images are put one over the other to specify the leak place 5 of liquid by a weight comparing part 44. Thus, the variation position of the infrared-ray radiation distribution is made to correspond to the position of the object image to easily specify the leak place 5.

Abstract: PURPOSE:To produce the subject compound useful as a low-toxic solvent, etc., on an industrial scale at a low cost by reacting gluconitrile, acetone cyanhydrin, ethylene cyanhydrin, etc., with water and phosphoric acid and esterifying the reactional product with an alcohol. CONSTITUTION:Water and phosphoric acid is added to a cyanhydrin such as glyconitrile, acetone cyanhydrin and ethylene cyanhydrin and made to react at 70 deg.C for 1hr under agitation to obtain a hydroxycarboxylic acid amide derivative. An alcohol (e.g. ethanol) is added to the reactional product and the reaction is continued at 70 deg.C for 8hr. After completing the reaction, the distillable fraction is separated by a thin-film evaporator and purified by distillation to obtain the objective hydroxycarboxylic acid ester (e.g. ethyl alpha-hydroxyisobutyrate) useful as a low-toxic solvent for coating, photo-resist, printing ink, etc., and raw materials for monomers, pharmaceuticals, agrochemicals, etc., in high yield while suppressing the etherification side reaction.

Title: Dryer canvas for papermaking
Inventor: MURATA YASUO
IPC: D21F7/08
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To firstly improve the regulation of the abrasion resistance and air permeability within a wide range of a dryer canvas for papermaking and secondly prevent wrinkles in selvedge parts of a wet web caused by a low adhesion degree between the wet web and the dryer canvas. SOLUTION: This dryer canvas for papermaking comprises firstly using monofilaments of a square cross-sectional shape as warp yarns in the dryer canvas for papermaking woven from the warp yarns and weft yarns. Since the warp yarns of the square cross-sectional shape are capable of providing a larger cross-sectional area than that of flat yarns, the weft yarns can readily be crimped by an increase in the warp yarn tenacity and the air permeability within a wide range can be regulated by an increase in weaving density. Polyester monofilaments can be used as the warp and weft yarns in order to obtain high abrasion resistance and high dimensional stability. Secondly, the monofilaments of the square cross-sectional shape are used in at least a part of the warp yarns in the selvedge parts of the dryer canvas to increase the contact area and adhesion degree between both lateral parts of the wet web and the selvedge parts of the dryer canvas.

Inventor: TSUDA YASUO
IPC: H01C7/02
Filed: 1988-03-10
Abstract: PURPOSE:To increase breakdown voltage and to improve characteristics, by mixing and baking barium carbonate, titanium oxide, lead oxide, yttrium oxide, calcium metasilicate and manganese dioxide. CONSTITUTION:Barium carbonate, titanium oxide, lead oxide, yttrium oxide, calcium metasilicate and manganese dioxide are weighed so as to obtain a material expressed by the formula. Powder is prepared by mixing, calcination and crushing, and a disk-shaped ceramic material is obtained. An electric com prising nickel plating and silver is formed. In this way, thermistor material having positive characteristics incorporating semiconductor elements such as barium titanate, niobium or rare earth elements, the lead oxide and lead metasilicate is manufactured. Since silicon is dispersed as the lead metasilicate in said constitution, the silicon is uniformly dispersed in a barium titanate based semiconductor ceramic. Thus, the breakdown voltage of the thermistor having the positive characteristics is high enough to improve the characteristics.

A variable gain amplifier 14 operates as an amplifier of 1/2 gain while there is the control signal SL, and in other time, operate as an amplifier of gain ''1''. Two vertical charge transfer signals phiV1, phiV2 are generated in 1THBL period every 5 or 6 when thinning out operation is made. Accordingly, an output signal 22 for succeeding 1 scanning line becomes signal amplitude twice that of output signal 23 of normal line. On the other hand, gain of the amplifier 14 is attenuated to 1/2 in this period. Thus, output VS becomes uniform amplitude, and thinning operation is also performed. Accordingly, the output signal can be used as video signals.
