Abstract:
A cause of deteriorating the hydrogen termination on the surface of a wafer is found to be water adsorbed on the surface. By exposing the wafer to an inert gas atmosphere containing an H2 gas so as to suppress the oxidation reaction due to the water, it is possible to improve the hydrogen termination on the wafer surface.
Abstract:
An apparatus comprises a bottle clamp having first and second clamp arms extending beyond respective first and second pivot axes. The clamp arms are held in a closed position. A rotatable locking element part is provided on an extension region of the first clamp arm, and a fixed locking element part is provided on an extension region of the second clamp arm.
Abstract:
A device for transferring articles between a first machine implementing intermittent movement of the articles at a first predetermined pitch, and a second machine implementing continuous movement of the articles at a second predetermined pitch. The device includes a flexible conveyor extending around at least two pulleys so as to have at least one rectilinear segment facing a conveyor of the first machine and a rounded segment facing a conveyor of the second machine. The flexible conveyor of the device carries laterally-projecting article-handling members arranged at regular intervals in such a manner that the handling members are at a pitch corresponding to the first pitch in the rectilinear segment. The rounded segment has a radius such that the handling members are at a pitch corresponding to the second pitch in the rounded segment.
Abstract:
The invention relates to a width-adjusting device for conveyor corridor(s), comprising a wide gear-reduction mechanism connected to the frame (5) of said conveyor, wherein said mechanism is arranged between the control shaft (12) and the wall(s) of said corridor. The device includes: a final drive capable of reverse operation and consisting of said control shaft (12) in the form of an endless screw and of a toothed wheel (11); and a system for controlling at least one of the walls of said corridor, consisting of an endless screw (13) and a nut, the endless screw being mobile or fixed relative to said toothed wheel (11). The shaft (12) of the final drive is a flexible shaft having a long length and engaging with the tension-retaining system (20) for absorbing the pulling and pushing forces in the rotation direction thereof.
Abstract:
A gripper unit for transport systems for supporting and transporting articles. A gripper unit that includes a gripper head with at least two gripper arms which can be opened and closed against each other. The top of the article to be gripped and to be transported is supported in the opening formed between the gripper arms. A shifting unit is supported in a flexible manner via a fastener directly supported at the transport system. Furthermore, the gripper unit is provided with a device for interchangeable support, adjustment and spatial determination of the gripper head in a first transport direction at the gripper unit. The device provides for the vertical movement of the gripper head contrary to the gripper unit and/or contrary to the transport system, which are arranged between the gripper head and the shifting unit or between the gripper head and the transport system.
Abstract:
A clamp grip for a container transport system including rare earth permanent magnets encapsulated in non-magnetic material such as high quality steel. Flexible positioning of the magnets allow for adapting to varied design specifications. A rotatable control cam or cams may be used to adjust grip arms between a grip and a release position. Air gap distances between permanent magnets may be designed to maximize repelling force to assist in the functioning of clamp grip mechanism.
Abstract:
A conveyor device for containers having a receiving rail for receiving a neck area of the containers, the containers being held by the receiving rail and are movable within this receiving rail. Guide mechanisms are provided with guide elements that are arranged beneath the receiving rail and guide the movement of the containers. The guide elements are movable in the longitudinal direction of the containers and the movements in the longitudinal direction of the containers of a plurality of different guide elements are mechanically linked to one another.
Abstract:
A dynamic storage for objects having an endless conveyor chain equipped with receptacles for the objects and having at least two contrarotating upper pulleys that are adjustable in height such that the conveyor chain forms two essentially vertical loops whose variable lengths are defined by the upper pulleys, the stationary lower pulleys rotating in essentially horizontal planes and being connected to the essentially vertical loops by curved guides for the conveyor chain.
Abstract:
An equipment (10) for producing vessels (12), includes at least one variable pitch wheel (38) arranged between a blower (14) having a first pitch (P1) and a filler (16) having a second pitch (P2), and that includes transfer elements (40) controlled by control elements adapted for selectively varying the pitch between two successive transfer elements (40) between an initial pitch (P) and a final pitch (P′), the initial pitch (P) being for example equal to once or twice the first pitch (P1) and the final pitch (P′) being equal to the second pitch (P2).
Abstract:
A conveyor line for products such as bottles, cans or similar containers with at least one guide railing that is adjustable across the direction of conveyance and is operable by at least one actuator drive, whereby stops which can optionally be moved into several preset positions in the adjustment path of the guide railing or the at least one actuator drive which define various railing positions and thereby delineate the adjustment path.
