摘要： An electro-pneumatic air pressure regulator includes a primary pressure introduction port, a secondary pressure output port, a pilot pressure chamber, a main valve for opening and closing a communicating conduit, a floating piston which actuates the main valve, a nozzle conduit via which the pilot pressure chamber is communicatively connected to the atmosphere, a flapper which includes a leaf spring facing an open end of the nozzle conduit, and an electromagnetic drive system which deforms the leaf spring to vary a position of the flapper relative to the open end of the nozzle conduit in accordance with the magnitude of an analogue input signal. The flapper includes a conical projection which projects toward the open end of the nozzle conduit. A conical recess corresponding to the conical projection is formed on an end face of the nozzle conduit around the open end thereof.

摘要： A parallel link robot includes a base, three servo motors disposed in the base, three arms, and a robot controller. Each of the three arms includes a first link and a second link that respectively include a first joint and a second joint. Each of the three arms is driven by a corresponding one of the three servo motors. The robot controller determines whether or not any of the first and second joints of the arms is dislocated on the basis of the torques of the three servo motors.

摘要： A hose clamp made from a unitary, spring steel band formed into a generally cylindrical configuration. The clamp has a support piece extending radially outwardly from one end of the spring steel band, a slot opening formed in the one end adjacent the support piece and extending a predetermined length in a circumferential direction of the spring steel band, a projecting piece formed at the other end of the spring steel band and fitting in circumferential relationship in the slot opening, and an upstanding tab formed at the distal end of the projecting piece and extending radially outwardly of the spring steel band. With this arrangement, when the spring steel band is deflected to its expanded position, the tab is retained on the support piece so as to temporarily lock the spring steel band in its open or expanded position.
