Abstract: PURPOSE:To improve spool strength and to decrease passage resistance, by providing a predetermined communication function and communication condition adjusting function in a hydraulic cylinder actuating variably regenerating circuit valve, independently of a hydraulic selector valve so as to simplify constitution of the variably regenerating circuit valve. CONSTITUTION:The control level of a pilot valve 29 is pulled in a direction J in the drawing, and if a signal pressure is generated in a pilot oil path 30, a hydraulic selector valve 3 is switched to a position G, and pressure oil from a pump 1 passes through an oil path 24 from a port A being allowed to flow into the head side oil chamber C of a hydraulic cylinder 2. And as the hydraulic cylinder 2 extends, return oil from a rod side oil chamber D is allowed to flow into the selector valve 3 from an oil path 25 and a port B. Here the return oil generates a pressure higher than the pressure in the head side oil chamber C, accordingly a regenerating circuit, is formed. So that pressure oil in a high pressure passage 15' can detach a piston 11 from a check part 10 via a notched hole 18 and an oil chamber 8, passing through a notched hole 12 and joining a bridge circuit 17.

Title: Method and apparatus for automatic weight correction
Inventor: TSUEDA KEN
IPC: G01G15/02

Abstract: PURPOSE:To realize quick and positive weight adjusting and correction of an object in safety by preparing a somewhat overweighted object, measuring the weight of the object and operating a required reducing amount, and then cutting the object by the required reducing amount. CONSTITUTION:A raw rubber body 2 is prepared while being somewhat overweighted as compared with final set weight. The raw rubber body 2 is stopped at a stop of a conveyor 1 and subjected to weighing. If the weight thus measured deviates from an allowable range, an operational controller calculates required reducing amount, number of corresponding cutting tools 7 and pushing strokes thereof. The raw rubber body 2 is then pushed in the direction of a cutter 6 and secured in place by means of a positioning/fixing unit 3. The cutter 6 is operated based on a signal fed from a controller to push a designated tool 7 into the side face of the rubber body 2 and cut off the rubber body 2 by an amount corresponding to the required stroke. The cutter 6 is eventually reset and stops rotation. When the tool 7 is separated from the rubber body 2, the fixing unit 3 is released and the rubber body 2 is weighed again thus confirming weight correction. The rubber body 2 is then discharged to next process through the conveyor 1.
