Title: Tube inside flaw detector
Inventor: KOUNO HIROSHI
IPC: G01N29/04
Filed: 1978-08-10
Abstract: PURPOSE: To control the flaw detcting speed with the use of a feeder and to indicate the position by inserting a sensor supporting cable into a tube to be detcted such as a straight or curved tube thereby to form a closed loop and by connecting a flaw detecting cable to a sensor.  
     CONSTITUTION: The force of a pressure fluid supplier 1 is used to feed a sensor supporting cable 4 from a take-up device 7 into a tube 15 to be detected by the action of the feeding roller 3 of a feeder 2 so that the joint 10 is jointed to make the sensor supporting cable endless. A flaw detecting cable 8 is jointed to a sensor 1. By pouring a pressure fluid together with the action of the roller 3, the flaw is detected while inserting the sensor 11 into a tube 15 to be detected. Since the sensor supporting cable 4 is made endless, the cable has its leading end prevented from being buckled so that it is turned in the tube with a preset force even with a change in the resistance in the tube thereby to make it possible to ensure the tests of the tube as a whole.

Filed: 1988-04-19
Abstract: PURPOSE:To obtain a toner having chemical and biochemical stability and safety, and stability against environmental conditions and to obtain an image having good color reproducibility, sufficient gloss, and causing no curling by using a specified binder resin. CONSTITUTION:The binder resin to be used is a polyol resin obtained by reacting an epoxy resin with a primary amine and a divalent phenol to extend the chain length, reacting monovalent compounds each having an active hydrogen with the epoxy groups at both ends of the epoxy resin, and further esterifying the secondary hydroxyl groups with a monocaboxylic acid, its ester, or lactone. The binder resin is obtained by introducing the flexible components into the epoxy resin to form a spongelike flexible structure, and reacting the epoxy groups of the resin with the active hydrogen compound to form the polyol resin, thus permitting the obtained image to be enhanced in color reproducibility, sufficient in gloss, and almost freed of curling, and the obtained toner to be chemically and biochemically stable, and stable against environmental conditions.

Title: Automatic excavating load measuring device for ground surface to be blasted
Inventor: FURUNO YOSHINORI
IPC: E21C41/26
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To judge accurate blasting amount and blasting position by detecting the working position and excavating load of an excavator at the time of detection of the cloud operation of a bucket and judging for display at the time of detection of the opening operation of the bucket whether the present process is the excavating process or loading process. SOLUTION: After confirming that an operating lever 13 is operated by an operator in cloud direction, an excavating counter is counted, excavating position and excavating time at that point are detected, and the detected value by a pressure sensor 17 is added to an accumulated value as a load pressure. During the excavating operation, this process is performed at specified intervals so as to obtain an average load pressure from the load pressure data obtained. Next a reference cycle time is compared with the time obtained by adding the error amount of an arrival time of a dump truck to a time requiring the opening operation of the bucket at the time of excavating operation, and it is judged whether the working cycle is composed mainly of excavating operation or of loading operation. Thus the blasting position and blasting amount can be judged correctly.
