A method for creating an electrical field around a stent and for supporting, electrically charging, and exposing the stent to dry particles comprising inert polymers, pharmaceutical or biological agents is provided.

Abstract: A holding jig (1, 2, 3) for a thin cylindrical work (W) includes a holding member (10, 10A, 10B) which holds the work (W) from an inner peripheral side and a diameter changing unit (25, 27) which changes a diameter of the holding member (10, 10A, 10B). The holding member (10, 10A, 10B) is made of metal and has a cylindrical shape and an elastically expandable or contractible diameter. The holding member (10, 10A, 10B) is configured with an outside diameter of the holding member (10, 10A, 10B) being held smaller than an inside diameter of the work (W) at the time of insertion into an inner periphery of the work (W) and being expanded after inserted into the inner periphery of the work (W) to hold the work (W) from an inner peripheral side of the work (W) with an outer peripheral surface in close contact with an entire inner peripheral surface of the work (W).

Abstract: This is a mandrel used to fabricate seamless belts including those used in electrophotographic marking systems. The mandrel has a center core unit with two circular caps on each side. In between the caps is sandwiched a deformable O-ring which is outwardly deformed upon tightening of the two caps together. Once a tubular sheet is placed over the mandrel, the elastomeric O-ring will hold the sheet in place for further processing.

Abstract: The process provides an expandable chuck with a variable diameter bulb having a variable wall thickness, the chuck being operatively designed to stretch the bulb to reduce its diameter for insertion into a photoreceptor pipe and upon relaxation to the compress the bulb so as to increase its diameter. The design provides a universal chuck to reduce the cost of changing to different diameter chucks in accommodating different size photoreceptors during the coating and drying process.

Abstract: A purge gas introduction system for an orbital tube welding setup is provided, configured to inject high purity inert purge gas to the interior volume of a tube or tubular component. An o-ring is interposed between an annular base and an annular ring, their junction forming an annular o-ring groove, each part forming one sidewall, with the o-ring fully recessed within the groove, protecting the o-ring during the insertion and removal of a tube. The annular base and an annular ring are configured to receive a tube terminus. The sidewalls of the o-ring groove are divergent one to the other, wherein as the annular ring is drawn towards the annular base, the o-ring is forced partially out of the groove, forming a substantially leak tight seal between the tube and the o-ring. A purge gas from an external source is transmitted to the annular base through a purge connector, then, in turn, introduced to the interior volume of the tube.

Abstract: Disclosed is a chuck comprising a base (10) in which a plurality of radially continuous, longitudinal slots (41) are provided for an individual clamping jaw (11, 21), respectively. The clamping jaws (11, 21) encompass one respective stopping surface (34) and can be displaced radially relative to the base (10) when a slanted clamping jaw surface (34) and a complementary surface (4) are moved towards each other such that a surface (14) of each clamping jaw (11, 21) clamps a workpiece that is to be retained around the longitudinal axis (20) of the base (10). Each clamping jaw (11, 21) is provided with a stop area (33 or 29) that extends on a plane running perpendicular to the longitudinal axis (20) of the base (10).

Abstract: A pneumatically controlled finger gripper having a supporting body (11) with a proximal and a distal end, a pneumatic control piston (12) guided and moving alternatively in the body, a compression disk (13) connected to, and moving axially with, the piston relatively at the distal end of the supporting body, and a flexible gripper element (14) assembled between the compression disk (13) and the distal end of the supporting body (11) and moving between a contracted and expanded position in response to the movements of the control piston with the compression disk between an inactive and active position.

Abstract: This invention relates to a pneumatically controlled finger gripper that has a supporting body (111) forming a chamber. A fixed axial rod (119) is secured to a proximal part of the body, extending in the chamber and emerging from a distal part of the body. A compression disk (113) is connected to the fixed rod. A pneumatic control piston (112) is guided along the axial rod and moves in the chamber (115) with respect to the compression disk (113) between an inactive position, at a distance from the compression disk, and a forward active position, near the compression disk. A flexible gripper element (114) is mounted between the compression disk (113) and control piston (112). The flexible gripper element moves between a contracted position and an expanded position in response to the movements ofthe control piston between the inactive and active positions of the compression disk.

Abstract: The invention pertains to a method and apparatus for clamping and subsequently machining a disk- or ring-shaped workpiece, wherein the workpiece is set down on a contact surface of a contact member made from elastomeric material. The workpiece is axially pressed against the contact surface with an elastomeric-material clamping member of a clamping device and simultaneously fixed in place perpendicular to the workpiece axis. Subsequently, the workpiece is machined with a tool.

Abstract: The invention concerns a clamping device comprising a tensioning spindle whereof one end has a first axially fixed support surface and whereof the other end has a second axially mobile support surface and mobile relative to the first support surface through a clamping element. Between the two support surfaces on the tensioning spindle are one or several elastomer adapter sleeves.

Abstract: The invention provides a mandrel comprising a shaft (1) the forward end of which has the shape of a forward pointing truncated cone (7), an expanding sleeve (15) constituted by a ring provided with longitudinal slits designed to slide over said conical forward end (7), and a piston (8) which is guided in a cylindrical bore provided along the axis of the mandrel shaft (1), from which it projects forwards, with the sliding of said piston (8) driving said sleeve (15) so as to control the gripping or the releasing on said mandrel of a workpiece to be machined.
