Abstract: A stamped precision lightguide interconnect centering element for use in a splice connector for making butt splices in optical fibers. The element is formed of a deformable metal shaped to define three surfaces (18,23,30) for contacting the fibers (18) to be spliced. The surfaces are formed between two levers (20,21) such that when the levers are moved toward each other the surfaces defining a fiber receiving passageway are closed onto a pair of fiber ends and the surfaces center the fiber ends and the levers afford a resilient spring compression reserve force on the aligned fiber ends to maintain them in contact. The element (11) is placed in a polymeric base (41) and a cover (60), that fits onto the base, is placed over the element to close the levers of the element when the cover is closed. A plurality of connectors may be molded integrally with a support in planar, arcuate or circular arrays.

Abstract: A flyback converter high voltage power supply which includes two switches (Q10, Q11) operating in push pull fashion to provide alternate polarity energy pulses to a load (30). A main component of the power supply is a transformer (T10), the primary winding of which is divided into halves (P1, P2). The secondary may also be split into halves (S1, S2), or may be configured without a split so long as the secondary and rectifier combination result in full wave rectification. The first of the two switches (Q10) couples an input voltage (Vin) across the first primary half (P1) to store energy in the magnetic core during a first time interval, and at the end of the first time interval disconnects the first primary half (P1) from the input voltage (Vin). During a second time interval, the energy stored in the magnetic core during the first time interval is delivered to the load (30) via the secondary winding (S1, S2). The second of the two switches (Q11) similarly couples the input voltage (Vin) across the second primary half (P2) to store energy in the magnetic core during a third time interval, and then disconnects the second primary half (P2) from the input voltage (Vin) at the beginning of the fourth time interval. During the fourth time intevral, the energy stored in the magnetic core is again transferred to the load (30) via the secondary. A duty factor modulator is used to control the switching of the first and second switches (Q10, Q11) to vary the length of the time intervals in reponse to variations in the load and input voltage.

Abstract: A bi-directional DC power controller is provided with a bi-directional DC switch (10) connected between a pair of terminals (12, 14) for connection to a pair of line power conductors (16, 20). A pair of difference amplifiers (U2, U3) are connected to receive voltages at these terminals. Each amplifier produces an output voltage signal which is proportional to the difference in voltages between these terminals when the voltage at one of the terminals is greater than the voltage at the other terminal, and is constant when the voltage at the second terminal is greater than the voltage at the first terminal. The outputs of the difference amplifiers are combined to produce a control voltage signal having a magnitude that is proportional to the absolute value of the difference between voltages at the terminals. This control signal is used to control the operation of the bi-­directional DC switch.

Abstract: In a laser printer, light beams (4) need to be focused onto a printing surface to form points where print indicia are to effect a print image. In a printer where it is desirable to have variable pitch print characters, a new method has been employed to create variable print character pitches. Multiple non-parallel points of light are emitted through a collimating lens (6) onto a wedge (8) shaped optical component which directs the multiple beams of light into parallel alignment. The optical wedge has one planar surface perpendicular to at least one light beam emitted through the collimating lens. This light beam is normal to the perpendicular planar surface and passes through the wedge without being deflected. The optical wedge also has one or more planar surfaces that direct the other light beams into parallel alignment with the undeflected light beam. By moving the optical wedge away from the collimating lens the pitch (distance) between the light beams is increased and conversely, by moving the optical wedge towards the collimating lens the pitch decreases.

Abstract: A method is used for the circumferential grinding of radially non-circular workpieces, in particular for the grinding of cams (15) or polygons. The workpiece is rotated about a first axis (18), and a grinding wheel (11) is fed along a second axis (13) which encloses an angle of preferably 90 with the first axis (18). In a plurality of steps corresponding in each case to a revolution of the workpiece, material is removed from the surface of the workpiece (15), starting from a blank contour, along spiral paths of an engagement point (20) to form intermediate contours and finally to form a finished contour by the workpiece and the grinding wheel (11) being rotated or fed in a predetermined manner as a function of data sets. In each case after an intermediate contour is obtained, a new data set is called up for the following revolution of the workpiece. A predetermined absolute dimension (RGactual) of the workpiece is continuously measured, and a deviation ([2645]RG) from a desired value (RGdesired) is determined. The deviation ([2645]RG) is compared (40) with threshold values, and if the deviation ([2645]RG) falls short of the threshold values a predetermined number of steps are skipped.

Abstract: A method and apparatus to calibrate and correct magnetic and geometrical distortions in an imaging system, specifically a computer tomography (CT) system, includes a calibration object which is placed on the surface of an image intensifier. An image frame of the calibration object is generated, and a vertical correction table is generated corresponding to the amount of image distortion caused to the image frame of the calibration object. The image frame is corrected using the vertical correction table, and the corrected image frame data is summed or averaged and either stored for further transformation into a slice image or used to generate a horizontal correction table to correct distortions in the horizontal direction. Once the vertical and horizontal correction tables have been generated using the calibration object, subsequent image frames are corrected using the correction values in the correction tables.
