Various embodiments of the present invention are directed towards a system and method for synchronized markers. A multiple-scanner X-ray system includes a belt passing by an upper X-ray scanner and a lower X-ray scanner. An upper belt portion is conveyed in a first direction by the upper X-ray scanner and a lower belt portion is conveyed in a second direction opposite the first direction by the lower X-ray scanner, to obtain upper and lower X-rays. A plurality of X-ray reactive markers are positionally synchronized relative to each other and the belt and conveyed by the belt to cause upper visual marker information, corresponding to a visual appearance of the upper scanned belt section, to be consistent with i) upper X-ray marker information of the upper X-ray, and ii) lower X-ray marker information of the lower X-ray.

A friction-type drive apparatus and a carousel comprising the same are disclosed. A friction-type drive apparatus, according to one embodiment, comprises: a motor; a drive pulley rotated by the motor; a belt connected to the drive pulley; a driven pulley rotating in accordance with the drive of the belt; a pressing unit contacting the inner surface of the belt; and an elastic unit for pressing the pressing unit toward the belt.

To stably convey a substrate (workpiece) while suppressing the workpiece from bending. A treatment device is provided. This treatment device includes: a conveying part that conveys a workpiece in a state where a flat surface of the workpiece is inclined around a conveying directional axis relative to a horizontal plane; and a treatment part in which at least one of polishing and cleaning is performed on the flat surface of the workpiece, wherein the conveying part has a drive part configured to be brought into physical contact with an end part of the workpiece and apply force in a conveying direction to the workpiece, a first Bernoulli chuck arranged to face the flat surface of the workpiece, and a second Bernoulli chuck arranged to face an end face of an opposite end part to the end part of the workpiece.

A load port including: a base as part of a wall partitioning a transportation space from an external space; an opening provided to the base; a door configured to open and close the opening and securing a lid to, and releasing a lid from, a container containing contents; and a first seal member for sealing the space between the base and the container. At least some of the container-side end surface of the door is located nearer to the transportation space than the container-side end part of the first seal member. The load port can keep a surrounding space clean when a FOUP is connected to a casing.

The present invention relates to a container search system comprising: a radiation irradiation unit for irradiating radiation to a container to be inspected; a detection unit installed opposite to the radiation irradiation unit to detect radiation having passed through a container; a transfer cart for loading an automobile thereon, on which a container to be inspected is loaded, and travelling along a search path formed between the radiation irradiation unit and the detection unit; and a circulation orbit unit formed to allow the transfer cart to circulate along the search path, wherein a primary side of a linear induction motor for generating a moving magnetic field is formed on either side among the transfer cart and the search path and a secondary-side reaction plate for inducing a secondary eddy current due to the moving magnetic field and generating a linear driving force is formed on the other side thereof. The container search system can transfer a transfer cart according to a linear motor scheme in a radiation search section, and thus can obtain a radiation search image of high quality.

An automated lumber handling system laser-scans the top profile of multiple stacks of lumber, each of which contain boards of a unique size. Based on the scanned profiles, the system determines the order in which individual boards from a chosen stack should be transferred to a saw. The saw cuts the boards to size and in proper sequence to facilitate orderly assembly of roof trusses or prefabricated walls. Some example systems lift individual boards by driving two screws, or some other piercing tool, down into the upward facing surface of the board. A track mounted cantilever, holding the screws and a laser unit, translates over the lumber stacks to retrieve and deliver individual boards and, while doing so, the laser repeatedly scans the stacked lumber profiles on-the-fly to continuously update the profiles. The open cantilever design facilitates replenishing the stacks of lumber.
