摘要:
A system for the post-treatment of preforms (9) produced by means of injection moulding, including a removal element (4) having at least one receiving element (5) for receiving a preform (9), and a device for moving the removal element (4) between two tool halves of an opened injection moulding mould and for moving the removal element (4) out of the opened injection moulding mould, a post-treatment element (6) having at least one post-treatment pin (7) having a pin-shaped passage element (7), of which one end can be connected to the environment or a vacuum or reduced-pressure source and of which the other end has an outlet (18) for a coolant, and a motion device with which the removal element (4) can be reciprocated relative to the post-treatment element (6) between a first position in which the post-treatment pin (7) is positioned within the receiving element (5) and a second position in which the post-treatment pin (7) is not positioned within the receiving element (5), wherein the removal element (4) and the post-treatment element (6) are so designed that in the first position coolant can be introduced by way of the coolant inlet into a preform held in the receiving element (5) in such a way that it can flow between the inside wall of the preform (9) and the outside wall of the pin-shaped passage element (7) to the coolant outlet (18) and can be discharged by way of the passage element (7).
摘要:
This relates to an injection-moulding machine comprising a hot runner for feeding a melt into a mould, a shut-off needle for closing or opening the hot runner, a piston connected to the shut-off needle, dividing the housing into first and second chambers, and a covering plate with a first and a second fluid 72 outlet, wherein the housing has a first fluid inlet, which is in connection with the first chamber, and a second fluid inlet, which is in connection with the second chamber, which are arranged in such a way that fluid can be transferred via the first fluid outlet of the covering plate into the first fluid inlet of the housing and fluid can be transferred via the second fluid inlet of the housing, and so fluid can be applied to the piston from both sides.
摘要:
A detector detects radiation from a mask to form an image, but the focal plane of the image is in front of the mask. Any particles arranged on the mask will be in focus. However, the pattern on the mask will be out of focus. It is therefore possible to detect the existence and location of particles on a mask having an arbitrary pattern. The depth of field of the detector is small and the focal plane is no further from the surface of the patterning device than two times the depth of field.

To calibrate a lithographic apparatus contrast in the aerial image is measured for a plurality of different settings of available manipulators of the projection system. Appropriate settings of the manipulators are determined as those giving the maximum contrast values.
摘要:
A catadioptric projection objective for microlithography has at least one curved mirror that is deformable and adjusting elements that can deform the deformable mirror. The adjusting elements are mated to given image errors and their correction. The invention is suitable for astigmatism, fourfold wavefront-deformations due to lens heating, compaction, and the like.
摘要:
An active body is provided that includes at least one active mass block made of monobasic or polybasic high-energy materials such as a nitrocellulose mixture, for example, comprising approximately 60 percent nitroglycerin and 40 percent diethylene glycol dinitrate, which is provided with structures both on a surface and on an interior. In addition, the inner structures can be filled with an active mass substance. The ignition is triggered by a pyrotechnical primer composition, which initiates the active body, preferably from the inside.
摘要:
An objective for a microlithography projection system has at least one fluoride crystal lens. The effects of birefringence, which are detrimental to the image quality, are reduced if the lens axis of the crystal lens is oriented substantially perpendicular to the {100}-planes or {100}-equivalent crystallographic planes of the fluoride crystal. If two or more fluoride crystal lenses are used, they should have lens axes oriented in the (100)-, (111)-, or (110)-direction of the crystallographic structure, and they should be oriented at rotated positions relative to each other. The birefringence-related effects are further reduced by using groups of mutually rotated (100)-lenses in combination with groups of mutually rotated (111)- or (110)-lenses. A further improvement is also achieved by applying a compensation coating to at least one optical element of the objective.

摘要:
A method and an arrangement for microlithographic projection exposure at high aperture achieve a contrast increase by the polarization of the light perpendicular to the plane of incidence on the resist. Arrangements are provided which influence the tangential polarization or the linear polarization adapted to the dipole illumination in the illuminating system and in the reduction objective.
