Abstract: A safety operation system for a manipulator is provided with a first operation section. The first operation section has a first movable section, and outputs a first operation signal representing the position and angle of the first movable section. A failure detecting section detects failure of the first operation section on the basis of the first operation signal, and outputs a detection signal. When failure of the first operation section is not detected, a conversion section converts the first operation signal into a control signal. A second operation section has a second movable section which moves in accordance with movement of the first movable section, and outputs a second operation signal generated in accordance with movement of the second movable section. A comparison section compares the control signal with the second operation signal, and outputs a deviation signal used for opening the second movable section.

Abstract: A pipe coupling for the union of a corrugated pipe therewith is formed of a pipe coupling proper and a lock cylinder for fixing a corrugated pipe. The lock cylinder is helically joined to the inner surface of the leading part of the pipe coupling proper and fixes the corrugated pipe by rotationally closing the lock cylinder helically tacked to the pipe coupling proper, and at the same time seals the pipe coupling proper by pressing the leading terminal part of the lock cylinder against a seal ring attached fast to the interior of the pipe coupling proper, enabling the corrugated pipe to be infallibly locked and sealed owing to the provision of a spacer adapted to preset and keep a closing distance for the lock cylinder. The spacer is detachably attached to the periphery of the pipe coupling proper.

Abstract: A meter at each user's house has a bar-coded user number shown thereon, and has a display section for displaying a reading. A data input terminal unit has a bar code reader for reading the user number and a keyboard for manually inputting a present reading. A data recording controller has a meter reading data file having a present reading for each user number. The data input terminal unit radio-transmits a read user number to the data recording controller and radio-receives a previous reading, corresponding to the user number, from said data recording controller. The data input terminal unit computes the amount used from this previous reading and the present reading manually input, and causes a printer to print meter reading data including this used amount on a reading slip while radio-transmitting it to the data recording controller.

Abstract: In an open state of a valve, when a valve outside sleeve is rotated in the rear portion of a housing, a valve inner sleeve is moved forward to close a fluid channel, thus stopping supply of compressed driving air. Simultaneously, a front end of the valve outside sleeve is moved forward while it abuts against the rear surface of a retainer. Therefore, brake rods biased by compression coil springs are also moved forward, and front surfaces of the brake rods are abutted against a brake disk to effect braking, thereby immediately stopping rotation of a rotor. The urging force applied on the brake disk is the compression force of the compression coil springs.
