Patent EP-0222521-A2 (EP)
Inventor: STEERE ROBERT
IPC: H01L21/304
Filed: 1986-10-16
Abstract: The edge grinder machine employs a centering station (13) in which a photosensor (14) measures a number of points on the periphery of a wafer (22) so that the shape of the wafer and location of the geometric center can be determined in a computer (19). A rotatable head (29) serves to position the geometric center of the wafer on a fixed axis and the wafer transferred to a grinding station (14) with the geometric center located on the central axis of a rotating chuck (68). During grinding, a grinding wheel (70) is moved in accordance with the differences between the detected shape of the wafer and a predetermined shape. The grinding wheel (70) is moved on an axis (y) perpendicular to an axis (x) passing through the centering station and grinding station in accordance with signals received from the computer (19).

Abstract: A beam of substantially coherent light passes through a window in a chamber and then through the chamber in a direction substantially parallel, and contiguous, to substrates in the chamber. The beam ionizes gases in a mixture in the chamber. The ionized gases combine to form a substance which becomes deposited on the substrate(s) as a layer or which etches a previously deposited layer on the substrate. As the beam moves through the chamber, it loses energy. Various individual, or combinations of, compensations for this loss of energy may include: (l) the substrate(s) may be tilted slightly to decrease the distance between the beam and the substrate(s) as the beam moves through the chamber; (2) the beam may be tapered in a direction along the substrate(s); (3) the rate and direction of the flow of a mixture of ionizable gases through the chamber may be adjusted; (4) the rate and direction of flow of a gas for neutralizing the ionization of the gases may be adjusted; (5) the rate of flow of the ionizable gases may be individually adjusted for each substrate; and (6) the rate and direction of flow of the neutralizing gas may be individually adjusted for each substrate. Lenses may be included in the window for producing the desired configuration of the energy beam. In another embodiment, the chamber may be disposed within a compartment. A first portion of the energy beam may be directed through the chamber. A second portion of the beam may be directed through a compartment area external to the chamber   and may then be redirected to pass throuqh the chamber in a direction opposite to the first portion and at positions substantially parallel, and contiguous, to the substrate(s).

Abstract: Flexure means (46) are provided for holding a tip member (28) of an ultrasonically reciprocating element (22) against lateral movement while freely permitting its longitudinal movement. The reciprocating element (22) is held fixed at a nodal point (36) distant from the tip member (28). The flexure means (46) have a natural frequency substantially the same as the reciprocating element so as to resonate in concert therewith. In one embodiment, a flexible disc (74) fixed around its periphery is centrally pierced to receive and engage the reciprocating element. In another embodiment, a plurality of elongated resonant supports (58, 62) are mounted at spaced radial positions on a fixture (48) provided with a central opening (50) through which the reciprocating element (28) extends so that free ends of the resonant supports are directed at and engage the reciprocating element. In this embodiment, at least two of the resonant supports (62) are adjustable toward and away from the longitudinal axis of the reciprocating element so as to properly position it. Also, at least one other (58) of the resonant supports is biased into engagement with the reciprocating element thereby holding the reciprocating element against the ends of the other resonant supports.

Abstract: In order to improve the running characteristics of a ski (1) with a spring board (2) which does not break out in the rear region in the case of short curves and when travelling diagonally on steep slopes during downhill skiing, the mass forces occurring of the skier, which are transmitted approximately in the vertical continuation from the lower leg to the ski boot, are supported resiliently in relation to the ski (1) at least at one point between the articulated connection of the front and rear ends of the spring board (2). In order to improve rigidity against twisting and lateral stability of the spring board (2) in relation to the ski (1), the spring board (2) is connected by its front and rear ends to the surface of the ski in an articulated manner so that the spring board (2) describes a vertical movement and in the longitudinal axis of the ski a horizontal movement relative to the surface of the ski. <IMAGE>

Abstract: In a broadband ISDN with separate switching facilities for narrowband and for broadband services, connection test signals are inserted into narrow-band signal gaps in the broadband signal in each access circuit involved in a broadband connection; these signals in each case contain the address of the relevant access circuit and the address of the distant access circuit which may be contained in corresponding connection test signals received from the distant end. The connection test signals are checked by one of the two access circuits for the occurrence of the addresses of both access circuits and a test result service signal is transmitted to the associated switching processor, possibly only with a change in the connection test signal or when it deviates from a nominal signal. <IMAGE>

Abstract: A circuit is specified which protects DC-operated electrical loads from damage and destruction resulting from both inverted polarity of the supply voltage as well as AC voltages, in particular including relatively high amplitude AC voltages. If an interrogation circuit confirms the presence of negative components in the applied supply voltage, a relay contact located in the input circuit remains open. The relay is triggered via a transistor and the contact closed only if the supply voltage is of the correct polarity. To reduce the power loss, PTC thermistors and an auxiliary voltage source are provided for supplying the relay coil. <IMAGE>

Abstract: The invention relates to a tool for manufacturing a circuit pattern of an electrical circuit board with conductor and earth tracks and connecting points for components, by cutting a copper plate with the aid of dies (1) and pressing pads (3) associated with the dies, along the edges of the tracks and connecting points. In this case, tool parts arranged on both sides of the copper plate (8) consist entirely of individual dies (1a) and moving individual pressing pads (3a) with mutually connecting die and pressing pad surfaces (1b, 3b) of a common rectangular cross-section, which are arranged side by side in the manner of a matrix grid. Program boards (4, 6) are provided on the die and pressing pad ends which are remote from the copper plate (8). The program boards have a relief of the circuit pattern (5, 7) constructed as a mirror image, for the dies (1) and pressing pads (3). When the program boards (4, 6) are pressed together between the mutually moving dies (1a) and pressing pads (3a), the copper plate (8) is cut in accordance with the relief (5, 7). <IMAGE>

Abstract: In a known design of liquid metal cooled fast fission nuclear reactor, the primary pumps (22) plug into the outboard ends of the high pressure pipes (28), leading to the development of a vertical load which has to be supported by substantial additional structure to avoid subjecting the reactor diagrid (18) to significant bending moments. The invention resides in connecting the inboard ends of the high pressure pipes (28) to the diagrid (18) via spigot and socket joints (40) so that the pipes are not rigidly connected at either end. With this arrangement loads are developed at each end of the pipes which combine to produce radial reaction loads acting on smaller moment arms whereby the total moments imposed on the diagrid are reduced.
