Abstract: A lathe of the type wherein work in the form of a rod (7) to be machined is held on said lathe while said work is inserted through a main spindle (3) includes a main spindle pedestal (2) immovably arranged at a predetermined position on a main frame (1) of the lathe, a hollow main spindle (3) rotatably supported on the main spindle pedestal, a guide bush mechanism (6) for guiding slidable movement of the work, a hollow quill main spindle (13) received in the main spindle (3) so as not to rotate relative to the main spindle but move in the axial direction, a chuck mechanism (16) disposed at the foremost end of the quill main spindle to firmly hold the work, a chuck opening/closing mechanism (22) for opening or closing the chuck and a quill main spindle displacing unit (34,35,36) for displacing the quill main spindle in the axial direction. The guide bush mechanism (6) includes a guide bush (8) of which cross-sectional shape coincides with that of the work to be machined. When a cutting operation is performed using a cutting tool (40) fixedly mounted on a tool pedestal, the work is protruded forwardly of the guide bush by actuating the chuck opening/closing mechanism. When a drilling operation is performed using a drill or the like, an index pin (39) is engaged with one of grooves on an index plate (38) disposed at the rear end of the main spindle while rotation of a built-in motor (4a,4b) is interrupted.

Abstract: An already- programmed anti-fuse (10) is DC soaked by passing DC current through the anti-fuse from a DC voltage source applied across the electrodes (14,18) of the anti-fuse (10). The anti-fuse resistance is lower when the DC voltage being applied such that the positive end of the voltage source is applied to the electrode (14 or 18) having the higher arsenic concentration. 
     An already programmed anti-fuse (10) is AC soaked, by passing alternating current pulses through the anti-fuse (10) from an AC voltage source applied across the anti-fuse electrodes (14,18). This AC soak may even be applied following the controlled polarity DC soak disclosed herein. The AC soaked anti-fuse resistance is even lower than the DC soaked anti-fuse resistance under the same soak current level.

Abstract: An electromagnetic shielding spring gasket assembly includes a coil spring for blocking the propagation of electromagnetic waves therepast. The coil spring includes a plurality of coils having a major and a minor axis and canted along a center line defined by an intersection of the major and minor axes and may be interconnected in a manner forming a radial garter-type canted-coil spring. A back angle of each coil defines the disposition of a trailing portion of each coil with respect to a line normal to the center line which determines a radial load-deflection characteristic of the canted-coil spring assembly. A front angle of each coil defines the disposition of a leading portion of each coil with respect to the normal line. The plurality of coils are noninvasively supported in an orientation for controlling the blocking of electromagnetic waves, for radial loading of the radial garter-type canted-coil spring and for controlling the resilient characteristics of the radial garter-type canted-coil spring.

Abstract: An improved method of, and electrical circuit for driving with precision and accuracy an electro-mechanical device such as a galvanometer is disclosed. The method precisely controls high speed linear scanning of the device in a forward scan segment of each cycle of operation, and further provides very fast re-set of the device without position overshoot during a re-trace segment of a cycle. The electrical circuit includes memory means for generating an electrical command waveform for controlling the device during each cycle of operation, and drive servo means for applying electrical power to the device. The servoing action of this circuit substantially eliminates any difference between an actual position of the device and the position directed by the command waveform during each forward scan segment of a cycle of operation, with the result that each forward scan segment is highly accurate and repeatable. During each re-trace segment of a cycle the circuit re-sets the device at high speed in a way that limits accuracy destroying effects of device overshoot and oscillation.

Abstract: In an ultrasonic imaging system capable of generating conventional envelope detected acoustic data and/or integrated backscatter acoustic data, a mechanism (32) is provided to select a plurality of pixels in a specified region of a two-dimensional ultrasonic image. The pixel values are processed to compute the average acoustic intensity (80) for the selected pixels. The average value is then processed (82, 84, 86, 90, 92, 94) to reverse any non-linearities between the calculated average value and the originally received acoustic signals which non-linearities may have been introduced by the compression, scaling and mapping of the data in order to display it on a conventional video monitor. The processed average acoustic intensity is plotted (42) and the procedure repeated at specified time intervals (36) to form a time-intensity curve whose characteristics are linearly related to the originally received acoustic signals. The characteristics of the time-intensity curve are calculated to provide further information about the irradiated body and the presence of any contrast agent therein.

Abstract: An optical fiber fusion splicer which includes means for supporting (92,46) two optical fibers (40,44) with their ends in an aligned facing relation along an axis (26), means for heating (22) the two optical fibers uniformly around their circumferences at their facing ends, and means for controlling (28) the power input to the means for heating so as to heat the optical fibers at their facing ends with the minimum power sufficient to fuse the facing ends. 
     A laser (22) preferably a carbondioxide laser, produces a laser beam (24) directed along a beam axis (26). The laser beam (24) first passes through a controllable shutter (28) and then through a beam expander (30) that produces an output laser beam (32) coaxial with the beam axis (26) but of expanded diameter as compared with the laser beam (24). 
     A parabolic mirror (34) having a reflecting surface (36) which is a parabolic surface of revolution or paraboloid, is positioned so that its parabolic axis is coincident with the beam axis (26). The expanded laser beam (32) is also coincident with the beam axis (26), so that the laser beam (32) reflects from the parabolic reflecting surface (36) through a focal point (38) of the parabolic mirror (34). This arrangement, together with the coaxial alignment and positioning of the ends of the optical fibers during splicing, ensures circumferentially even heating of the ends of the optical fibers during the splicing operation. 
     A first length of optical fiber (40) to be spliced, from which the buffer layer (16) has been removed, is supported in a first clamp (42). The first clamp (42) positions the first length of optical fiber (40) between the laser (22) and the mirror (34) coincident with the beam axis (26). A second length of optical fiber (44) to be spliced, from which the buffer layer (16) has been removed, is supported in a second clamp (46). The second clamp (46) positions the second length of optical fiber (44) coincident with the beam axis (26) but further from the laser (22) than the mirror (34) along the beam axis (26). The mirror (34) has a bore (48) therethrough, coincident with the beam axis (26), of sufficient diameter so that the second length of optical fiber (44) can pass therethrough.

Abstract: A composition for removing resists and etching residue from substrates containing at least one nucleophilic amine compound having oxidation and reduction potentials, at least one organic solvent, water and, optionally, a chelating agent is described. The chelating agent is preferred to be included since it provides added stability and activity to the cleaning composition so that the composition has long term effectiveness. If a chelating agent is not present, the composition, while providing for adequate stripping and cleaning upon initial use of the composition following mixing, has only short term stability. In this latter instance, the nucleophilic amine compound and organic solvent components of the composition preferably are maintained separate from each other until it is desired to use the composition. Thereafter, the components are combined. Following use of the composition, the non-used portion of the composition can be disposed of or be reactivated by the addition of a chelating agent.
