Patent EP-0344918-A1 (EP)
Inventor: FISHER PETER ALLEN
IPC: H01J37/317
Filed: 1989-05-03
Abstract: A scan controller (80) for an ion implantation system includes a compensation circuit for generating a scanning signal from a triangle voltage signal. The scanning signal causes an ion beam (18) to be deflected so that, in the variety of geometries describing the orientation of the target (36) in the implantation system, the position of the intersection of the ion beam (18) with the planar target (36) surface changes linearly with time. In one embodiment the scanning signal has the form v(t) = -d -e/(t+c). In other embodiments the compensation circuit approximates the above function by means of polynomials.

Abstract: The alignment of the pouring nozzle (8) of a continuous casting installation having a plurality of mould blocks (1) connected together to form two endless tracks which cooperate to define the mould cavity (2) is carried out by connecting a dummy nozzle (8′) of the same size and shape as the nozzle (8) to the tundish mounting stand (30) and aligning the dummy nozzle (8′) with the mould cavity (2). The carriage (6) is then moved to a position remote from the casting machine (3) and the distances of the dummy nozzle (8′) from sensors (14, 17) are measured. The nozzle (8) is then connected to the tundish mounting stand (30) and the distances of the nozzle (8) from the sensors (14, 17) are again measured. The mounting stand (30) is then moved by actuators (9, 10, 11) with respect to the carriage until the position of the nozzle (8) is precisely the same as the previous position of the dummy nozzle (8′) whereby the nozzle (8) is then aligned with the mould cavity.

Abstract: A thrust plate (64) for a gear pump or motor (10) which permits the use of high pressure fluid from the outlet side (30) thereof to lubricate the bushings and trunnions (36, 38, 40, 42, 48, 50, 52, 54) therein. The thrust plates (64) (see Figs. 5 and 6) include two small bores (82, 84) which pass therethrough and which are in fluidic communication with the inlet side (28) of the pump via the surface (66) of the thrust plate that confronts the gears (14, 16) within the pump. The foregoing bores (82, 84) are also in fluidic communication with the bushings (36, 38, 40, 42) by means of associated slots (86, 88) in the opposite side of the thrust plate. The opposite ends of the bushings (36, 38, 40, 42) are in fluidic communication with fluid at atmospheric pressure. By minimizing the size of the foregoing bores (82, 84) and by allowing the passage of fluid through same to the inlet side of the pump via the gear tooth confronting surface (66) of the thrust plate, pressure gradients are created across the trunnions (48, 50, 52, 54) and their associated bushings (36, 38, 40, 42). These pressure gradients permit high pressure fluid to traverse outwardly from the thrust plate (64) along the surface of the trunnions (48, 50, 52, 54) to the approximate end thereof to lubricate same and then to move inwardly along the trunnions (48, 50, 52, 54) toward the thrust plate (64) and to pass therethrough via the bores (82, 84) therein.

A mirror holder (2) having a spherical sliding surface (2a) whose center exists at the center (3a) of reflection of a reflecting mirror (3) is fixed to an L-shaped waveguide member (4) which permits the passage of a laser beam through it. A mirror retaining member (1) holds the reflecting mirror (3) and has a sliding surface (1a) which slides over the sliding surface (2a). A micrometer (5) pushes the mirror holder (2) in a transverse direction and slides the mirror retain- ling member (1) in a direction represented by an arrow (B). Even when the mirror retaining member (1) is slid by the micrometer (5), the center (3a) of the reflecting mirror (3) stays unchanged and only the reflection angle can be adjusted easily.

Abstract: In the interior of the housing (15) of an accumula­tor (10), a metallic bellows (30) and a self-seal mechanism (37) are arranged. The metallic bellows (30) partitions the interior of the housing (15) into a gas chamber (45) and a liquid chamber (41). The self-seal mechanism (37) includes an elastic seal member (35) and a face (36) which the elastic seal member (35) opposes. When the bellows (30) is compressed to the predetermined extent due to introduction of a compressed gas into the gas chamber (45), the elastic seal member (35) is brought into contact with the face (36), thus closing a flow port (18). The elastic seal member (35) has a slanted face (52), so that a wedge-shaped liquid guide gap (55) is produced when the elastic seal member (35) is in contact with the face (36). When, in this con­dition, the compressed liquid is introduced into the flow port (18), part of the liquid enters the liquid guide gap (55), thus permitting the seal member (35) to easily separate from the face (36).

Abstract: A method and an electronic slide gauge serve to measure a length. The slide gauge comprises a rod with a longitudinal marking and a cursor, which is arranged on the rod in a longitudinally displaceable fashion and has two sensors that are mutually offset in the longitudinal direction in such a way that the zero crossings of the signals generated by the sensors do not coincide. In order also to be able to measure lengths in the presence of a considerable DC drift, the zero crossings (ND) of the signals are determined by firstly determining the maximum values (MX) and minimum values (MN) of the signal values (U) and then determining the zero crossings (ND) as an arithmetic mean value. By averaging a relatively large number of zero crossings, the respective zero level (UN) is then determined. <IMAGE>

Abstract: Air flow in an elevator hoistway is directed to the sides of the elevator car in order to avoid creating air turbulence in the path of travel of the counterweight assembly and in the area of hoistway doors and sills. Control of the air flow is accomplished with pitched air deflectors mounted on the roof of the car. Each air deflector comprising a shear panel and a pitched panel serves to deflect air in the hoistway away from the counterweights and to one side of the car. Shear panels are mounted on the top and bottom of the car to cover the landing sills as the car moves past floors in the hoistway whereby air is sheared away from the sills and air intercepted by the car travel is kept from passing hoistway elements which induce noise and vibration of the car.
