  • Patent number: 11505216
    Abstract: Provided is a transfer cart that that has a simple structure, facilitates operation in front and back spaces of a moving direction, and does not take up a redundant transfer space in a locations where operation is not performed. The transfer cart includes a running frame, a main carrier capable of carrying thereon an object to be transferred, and moving-direction operation decks disposed at front and back of the moving direction on the main carrier and running frame. The moving-direction operation decks are configured to change angle with the main carrier in accordance with the radius of curvature of a track, and configured to have a variable height mechanism to be able to change height thereof in the up and down direction.

  • Patent number: 9076037
    Abstract: A background image holding unit is configured to hold a background image. A threshold table holding unit is configured to hold a threshold. A previous frame image holding unit is configured to hold a previous frame image. An object extraction unit is configured to perform a background subtraction process of calculating difference values between the background image and a latest image and detecting a pixel whose calculated difference value is equal to or larger than the threshold as an extracted object, and configured to perform a process of judging the magnitude of difference between the background image and latest image. The object extraction unit is configured to update the background image and threshold in accordance with the magnitude of difference between the background image and latest image.

  • Patent number: 6360671
    Abstract: A friction drive system trolley conveyor includes a conveyor rail having a circular cross-section, laid along a conveyor line, multiple J-shaped rail suspension members that bear the undersides of the rail at intervals in the longitudinal direction, multiple, inverted J-shaped hook members that move along the rail, engaging the upper side of the rail, a driven bar hung between hook members for suspending a conveyed article, and a friction drive embracing the driven bar on both sides to effect conveying movement. The friction drive system trolley conveyor is able to convey heavy articles in a stable manner with minimum noise and without roll, is easily constructed, installed and maintained.
