Abstract: Workpieces are gripped by a pair of jaws having rear end parts contained within a housing. A single pinion borne within the housing meshes with racks formed on the rear end parts and the jaws are synchronized to operate in opposition to each other.
Abstract: A pressure switch wherein electrode plates are provided on both sides of a pressure conductive rubber plate. The pressure switch is interposed between a body and a receiving block slidably fitted to the body so that both electrodes may be connected with each other by connecting the rubber plate into conductive state to obtain an electric signal across the electrodes. The pressure applied to the rubber plate is regulated by a variable spring.
Abstract: An air assisted sliding device has a pallet supported on a base. The pallet has a recess provided on the periphery of its bottom surface in which a flexible tubular sealing member is mounted. The sealing member has a memory normally contracting it so as to be flat. An air passage communicates with the interior of the flexible sealing member so that compressed air can be fed to it. A groove is evenly provided on the bottom surface of the pallet within the bounds of the recess and a separate air passage for feeding compressed air or vacuum air is communicated with the groove so that the pallet may be provided with an air film of compressed air or may be stopped and a vacuum applied to attract the pallet to the base at a predetermined position on the base. A timing belt drive or an electromagnetic motor is used.
