  • Publication number: 20130098274
    Abstract: A sample stage device (10) is so configured as to calculate ideal position information xtg(i), tg(i) per predetermined period that is unaffected by drive conditions relating to gaps (25, 26), etc., and to determine, per predetermined cycle and in real time, deviations dx(i), dy(i) between real-time measured positions x(i), y(i) by position detectors comprising laser interferometers (33, 34), etc., and ideal position information xtg(i), tg(i). In addition, it calculates, based on deviations dx(i), dy(i) thus determined, such speed command values vx(i), vy(i) for motors (27, 28) that measured values x(i), y(i) would follow ideal position information xtg(i), tg(i), and performs stable and high-speed positioning control for a sample table (11) through feedback control that controls speed in real time.

  • Patent number: 8336722
    Abstract: A pallet rack and method for use of same are disclosed. Three panel frames interconnected by two parallel cross members define two lower pallet receiving areas and two upper pallet receiving areas. A catch tray is disposed beneath the two upper pallet receiving areas to catch and redirect fluid and debris to prevent cross-contamination between pallets. The catch tray includes a primary tray and a slidable dependent tray extendably coupled to the primary tray. The slidable dependent tray extends from a retracted position within the primary tray to an extended position having a general decline from the first panel frame to the second panel frame to furnish a slanted surface therebetween. Retraction of the dependent tray provides clearance for fork lift tines to access the rear upper pallet receiving area.

  • Publication number: 20120318178
    Abstract: A folding platform assembly for the top deck of motor vehicle carrier trucks. The platform features a grate, whereupon a person may safely and comfortably walk along the length of the truck. The platform also features a safety net system affixed to the grate to catch a person in the event of a slip, trip, or fall from the grate. The grate has an access panel for easy ingress and egress to the platform from a ladder or set of steps. When storing or transporting the platform, a folding mechanism pushes the platform into its closed, substantially-vertical position. This same mechanism pulls the platform into its open position when it is ready for use.
