Abstract: A workpiece machining jig includes: a base member of an H cross-sectional shape integrally having two vertical flanges and a web having an interior hollow portion and extending horizontally to connect between the vertical flanges; first and second pallets fixed to the opposite surfaces of the web for placing thereon four workpieces, two workpieces on each of the pallets, in a horizontal posture. Each of the pallets has a pallet-side communication hole communicating to the hollow portion, and each of the flanges has a flange-side communication hole communicating to the hollow portion. The pallet-side communication hole of each of the pallets and the flange-side communication hole of a corresponding one of the flanges are interconnected by a tube extending in the hollow portion. Thus, four workpieces are machined concurrently using the single workpiece machining jig.

Abstract: A tool stocker includes main stockers for holding a plurality of tools detachably mounted on a main spindle for machining a workpiece, an auxiliary stocker for holding and transferring tools to and from the main stockers, and a tool transfer mechanism for transferring tools between the main stockers and the auxiliary stocker. The auxiliary stocker includes a plurality of tool pods for removably supporting the tools therein, a rail in sliding engagement with outer surfaces of the tool pods, a chain for moving the tool pods in sliding engagement with the rail, and a motor for actuating the chain. The rail has a recess defined therein in alignment with the tool transfer mechanism, such that the tools transferred by the tool transfer mechanism pass through the recess.

Abstract: The agitator of the present invention comprises: a drive source; a differential unit; a rotation-direction switching unit; and a brake unit. The drive source generates rotational driving forces. The differential unit and rotation-direction switching unit are positioned in a driving-force transmission path between agitation vessels containing agitation-target material. The brake unit alternately stops the rotation of two rotating shafts extended from the differential unit. Here, the differential unit of the agitator has functions of receiving the rotational driving forces from the drive source and transmitting the rotational driving forces to the two rotating shafts in a differential manner. The rotation-direction switching unit has a function of inverting the rotation direction of the rotational driving forces transmitted to the agitation vessel while the rotation of the rotating shaft is being stopped by a brake.

Abstract: A denture base stabilizing sheet fitting the shape of the user's jaw serves to stabilize the denture base on the jaw. The sheet has a generally trapezoidal configuration, optionally with a cut out in the center, with each corner of the trapezoid having smooth edges. The sheet is made from a composition containing 41 to 43 wt % ethyl methacrylate polymer, 37 to 39 wt % butyl phthalyl butyl glycolate, and 17 to 23 wt % glyceryl triacetate.

Abstract: Disclosed is a disk drive which includes a disk, a spindle motor for rotating the disk, an actuator for moving a transducer over the disk, a pivotably mounted latch for locking the actuator, and a controller for rotating the spindle motor at at least two rates. The latch has two ends. On one end, the latch includes a locking member for engaging a notch in the actuator. On the other end of the latch is a vane for producing a force on the latch caused by the airflow from the rotating disk in the disk drive.
