6 results about "Exit side" patented technology

A lens member includes at least one of the annular prisms including a facet at an edge between an inner annular surface and an outer surface of the at least one of the annular prisms. The prisms with facets may be provided at a central portion of the lens member and the facets are configured to refract light toward a light-exit side of the lens member.

The present invention relates to an edgewise coil winding machine, including: a device for clamping the exit side of flat rectangular wire material by the first clamp installed in rotating mode on the wire material feeding side of the rotating plate which performes coaxial installation with the rotating shaft; a device for decorticating the nearby clamped part of the flat rectangular wire material clamped by the first clamp; a device for clamping the exit side of flat rectangular wire material between the rotating shaft and weight balancing block by rotating the rotating plate with a certain angle and pressing the wire material on the winding shaft, then clamping the exit side of the wire material by the second clamp; a device for pushing the winding shaft and the weight balancing block upward the same time as winding the wire material on the winding shaft by rotating the rotating shaft; a device for decorticating the end of the coil; a device for welding the decorticated end and exit side of the coil by electrodes; a device for clamping the wire material to be winded by the first clamp and cutting the wire material at the point that is in a little front of the clamped part of the wire material; and a device for lifting the winding shaft and moving away the finished coil from the winding shaft.

A re-closable valve (1, 100, 700, 800) for use in sterile fluid transfer has a body (5) with open entry and exit sides (2, 3) and a passageway (4) for fluid therebetween. The entry side is connectable to an opening of a separate vessel and the exit side is connectable to downstream processing. The entry side includes a first rupturable seal (5b, 500) blocking the opening of the entry side. A piston (9) is connected to an actuator (7) via a cam mechanism (8, 85, 10) which moves the piston (9) axially in the passageway (4) and to the first seal (5b, 500). On movement of the piston (9) during a first actuation, the first seal (5b, 500) is torn free from the entry side to open the valve for fluid transfer. A sharp rim (15) surrounds the opening of the entry side and a curved surface area (193) encircles the piston exterior proximal the entry side. The valve (1, 100, 700, 800) can be re-closed by moving the piston (9) during a subsequent actuation thus engaging the sharp rim (15) with the curved surface area (193) which plastically deform to from a second seal. Arrangements are included to enable the valve (1, 100, 700, 800) to be multiply re-opened and re-closed, if desired.

The invention relates to an aberration correcting device for correcting aberrations of focusing lenses in an electron microscope. The device comprises a first and a second electron mirror, each comprising an electron beam reflecting face. Between said mirrors an intermediate space is arranged. The intermediate space comprises an input side and an exit side. The first and second electron mirrors are arranged at opposite sides of the intermediate space, wherein the reflective face of the first and second mirror are arranged facing said intermediate space. The first mirror is arranged at the exit side and the second mirror is arranged at the input side of the intermediate space. In use, the first mirror receives the electron beam coming from the input side and reflects said beam via the intermediate space towards the second mirror. The second mirror receives the electron beam coming from the first mirror, and reflects the electron beam via the intermediate space towards the exit side. The incoming electron beam passes said second mirror at a position spaced apart from the reflection position on the second mirror. At least one of the electron mirrors is arranged to provide a correcting aberration to a reflected electron beam.
