Title: Arrangement for projecting pattern on photo mask onto semiconductor wafer has supporting substrate surface with filter structure so more of perpendicularly incident light beam is reflected than of beam incident at inclination angle
Inventor: KUNKEL GERHARD
IPC: G03F7/20
Filed: 2003-11-05
Abstract: The arrangement has a photo mask (10) and a transparent supporting substrate (16) arranged at a distance from the photo mask and essentially parallel to a first surface of the photo mask. A second surface (161) of the supporting substrate has a structure (17) for forming a filter so that a light beam (20) incident perpendicularly on the surface is reflected in a first proportion and a second light beam (22,24) incident at an inclination angle is reflected in a second smaller proportion. An independent claim is also included for a projection equipment for projecting a pattern on a photo mask, preferably onto a semiconductor wafer.

IPC: G06V30/166
Filed: 1995-03-08
Abstract: The invention concerns a process for improving the recognition of typed text with fixed character spacing, wherein the blackened segments (S) from a uniformly printed area of a document, for which a character geometry characteristic of the font in question can be given, are provided with circumscribing rectangles. The geometry data of the resultant rectangles are determined. From the geometry data of the rectangles which watch the characteristic character geometry within a predetermined permissible margin, ideal character expectation zones are calculated for the rectangles whose geometry data are outside the predetermined permissible margin. Only the blackened segments lying within the ideal character expectation zone or the rectangles whose geometry data correspond to the characteristic character geometry within the predetermined permissible margin are considered for recognition purposes.

Patent DE-19540767-A1 (DE)
Inventor: SCHAEFER-LORINSER FRANK DR RER
IPC: G07F7/08
Filed: 1995-11-02
Abstract: The method detects unauthorised use of a chip card in at least one terminal having at least two first memories (10,11,12) which can each store the identity of a chip card or a group of cards and the number of units used with these chip cards. A chip card is inserted into the terminal which can query the identity and the count state of the inserted chip card. It is determined whether the identity of the chip card is already stored in the first memory. The number of units used up while using the terminal are counted. If the identity of the card is not registered in any of the memories, the identity and the number of units counted are stored in one of the memories , when at least one of the memories is not described or when the counted number of units is greater than the smallest number of consumed units contained in the memory. If the identity of the chip card is registered in the memory, the number of consumed units stored in the memory and the number counted are added together and the sum is compared to a maximum value. An unauthorised use of the chip card is indicated when the summed value exceeds the maximum value.

Title: Plastic skin manufacture with constant skin thickness
IPC: B29C33/02
Filed: 1996-01-29
Abstract: A process for manufacturing a plastic skin uses two or more moulds (a,b) which are supported in a rotatable heating vessel (6). During rotation of the heating vessel (6) a plastic powder is dispersed evenly over the inner surface of one of the moulds, melted and sintered while the temperature of the other mould settles to the correct process temperature. In the following process stages: (a) the mould containing the sintered plastic skin is moved to a cooling station (2) and replaced by a new mould while simultaneously a powder container (5) is connected to the other mould in the heating vessel (6) whose temperature has stabilised at the correct process figure; (b) the heating vessel (6) is rotated to heat the plastic powder in the one mould and also allow the new mould to attain the correct temperature; (c) rotation is stopped and the powder container (5) is disconnected prior to removing excess powder from the mould; (d) rotation recommences and the cycle is repeated with stage (a). In a process variation two or more moulds (a,b) are heated simultaneously in a preheating station (7) and are taken from this station one after the other to the heating vessel (6).  Another mould replaces the one just removed. Process equipment includes a rotatable heating vessel (6) holding two or more moulds (a,b) and containing a heat transfer medium which contacts the outer side of the moulds supported in the vessel during rotation of the latter. A control and conveying system transfers moulds (a,b) from the heating vessel (6) to a cooling station (2), replaces a transferred mould with a new one and attaches a powder  dispensing container (5) to the other mould. Preferably the moulds (a,b) are heated in a preheating station (7) and after transferring to the heating vessel (6) attain a stabilised correct process temperature. The powder container (5) is only disconnected from a mould(a,b) when the thickness of the plastic skin reaches a desired figure and the polymer is fully melted and sintered.
