Therefore, a resilient seal ring 4 is stretched and spread, and forced into pressure contact with the inner peripheral surface of the workpiece 1 to integrally hold the workpiece 1 and the jig body 2. In which case, when a pressure liquid seal valve is close and is separated away from a pressure liquid feed source, the workpiece 1 held integrally with the jig body 2 is carried to a centerless polishing machine where the outer peripheral surface thereof is polished. However, since a number of the seal rings 4 are forced into pressure contact with the workpiece 1, which is held by the jig without a gap therebetween, deformation due to polishing resistance is not produced.

Title: Method for detecting failure of original point switch in industrial robot
Inventor: SHIRAKI SHINJI
IPC: G05B19/19
Filed: 1984-03-19
Abstract: PURPOSE:To improve the working efficiency of a robot and to prevent the robot previously from runaway by rotating a rotary shaft in a direction changing the output of an original point switch and discriminating whether the output status of the original point switch is changed or not within a maximum regulated time to detect failure. CONSTITUTION:When the original point switch 8 is normal, light is interrupted by a dog 9 and the output of the original point switch 8 is turned to an ON signal. The original point switch 8 is decided as failure when said output is an OFF signal, and in case of the ON signal, decided as normal status and the rotary shaft 6 is rotated in the counterclockwise direction (b) at a fixed speed (v). In this case, the time required for the end point 10 of the dog 9 to move a distance L becomes Tmax=L/V, and if the original point switch 8 is in normal state, the output of the original point switch 8 may be turned from the ON signal to the OFF signal before the passage of Tmax. Therefore, the time of Tmax is controlled, and when the output of the switch 8 is turned to the OFF signal before the passage of Tmax, the switch 8 is decided as normal status. If the maximum regulated time Tmax has been passed without change of the output state, the switch 8 is decided as failure.

This eletrochemical regulator for the O2 concentration is capable of remarkably increasing the reverse diffusive migration of water from the cathode 2 into the anode 1. Water produced in the cathode 2 and water migrated into the cathode 2 are mostly returned through the solid polyelectrolyte film 3 to the anode 1. Thereby, a reservoir for the produced water, a reservoir for feed water and a pump can be omitted.
