    摘要: A sluice valve arrangement is adapted to make an air-tight partition or communication between a vacuum treatment chamber and the atmosphere or a pre-chamber. This arrangement includes a valve seat member comprising a cylindrical or spherical member having therein an opening, a pair of guide rails attached to the inner circumference of the seat member, a valve member movably supported on the guide rails, and means for air-tight engagement of the valve member and the valve seat portion of the seat member. The valve member has a curvature equal to that of the cylindrical or spherical member, and the engagement means comprises a plurality of bellows expandable by a compressed gas or air.

    摘要: A vacuum furnace for heat treatment comprises a heating furnace proper, pre-exhaust chambers, one adapted to feed a workpiece into the furnace proper therefrom and the other adapted to discharge the workpiece out of the oven proper thereinto, vacuum valves for partitioning between the oven proper and the respective pre-exhaust chambers, and a line assembly for deliver of the workpiece from the feed chamber into the discharge chamber through the furnace proper. A heating chamber forming part of the furnace proper is positioned on the upper part above the deliver line assembly, and an externally operable elevating means is disposed in the furnace proper. The work pieces carried by the delivery line assembly, and lifted to the heating chamber where it is heated.

    摘要: In exemplary implementations of this invention, a handheld, collapsible input device (CID) may be employed by a user to input and manipulate 3D information. The CID telescopes in length. As a user presses the CID against a display screen, the physical length of the CID shortens, and the display screen displays a virtual end of the CID that appears to project through the screen into the virtual 3D space behind the screen. The total apparent length of the CID, comprised of a physical portion and a virtual portion, remains the same (after taking into account foreshortening). Thus, the user experience is that, as the user holds the physical CID and pushes it against the display screen, the end of the CID appears to be pushed through the display screen into the virtual 3D space beyond it. The CID housing may include a push button for user input.
