Abstract: There is disclosed a semiconductor chip and a method of directing a first writing laser beam and a second scanning laser beam across the surface of the semiconductor chip. The semiconductor chip includes first and second edges and a recognition pattern to be scanned by the scanning laser beam to facilitate the control of the relative movement of the semiconductor chip and the writing laser beam. The recognition pattern includes a pair of first enter codes disposed respectively along the first and second edges. Each of the first enter codes includes a synchronization mark and a step recognition mark disposed behind the synchronization mark considering that the scanning laser beam is directed from its edge to first scan the synchronization mark and then the step recognition mark.

Abstract: The isolation arrangement has a tubular element (1) made of elastic plastic with at least two webs (2,2) on the outer surface of the element. The webs rest with their free ends (4,4) against the ferrite core (5) when the element is inserted into the hole in the core. Two webs are formed and lie diametrically opposite one another. Alternatively, the number of webs may depend on the number of turns and the depth of the coil. The element and its webs are made in one piece from an elastomer. The length of the element and its webs is roughly the same as the length of the core.

Abstract: In a tissue paper machine, the dust that is released when the web is creped off the Yankee dryer (3) constitutes a major work environment problem. To provide an improved extraction of the dust and thereby improve the work environment for the operating personnel concerned, a dust extractor (25 sec ) having an internal space (39 sec ) and a web stabilizing, imperforate plane (37 sec ) is mounted immediately adjacent to an intended path of travel for the creped web (1), so that the web during its transportation will place itself in a fixed position close to the imperforate plane (37), and, at least an essential part of an entrained boundary layer of dust containing air is eliminated solely through suction to the internal space (39 sec ). The suction is carried out at the rear and/or front edge of the extractor (25), and suitably both on the overside and the underside of the web (1). Dust that does not become entrained in the boundary layers will be sucked away by at least one dust suction box (55) having a sloping suction box cover (57), and mounted under the web (1) and spaced therefrom at doctor beam (11). Preferably, an air stream, which is of sufficient force to carry the dust and caused by the suction, is made rise towards the web (1) between the dust suction box (55) and a dust extractor (27) mounted downstream of the latter.

Abstract: The circuit boards (7) are kept in an evacuated bag (6). This bag (6) is fastened inside a pressure vessel (1), which is filled with hydraulic fluid (10), which is then pressurised and heated. Once the circuit boards have been pressed together to form a multi-layered printed circuit board (7) and cured, the hydraulic fluid (10) is cooled, its pressure reduced and then drained from the pressure vessel (1). After removal of the upper plate (4), the finished multi-layered printed circuit board (7) is removed from the bag (6). It is to be regarded as the advantage of this invention that the hydraulic fluid (10) is prepared not only as a good pressure transfer medium but also as an advantageous heat transfer medium and there is no need for a sophisticated conventional press system, with the enormous difficulties of sealing the pressing space. Since the circuit boards (7) are kept in the bag (6), only a relatively small space within the bag (6) is evacuated. <IMAGE>
