Granted: 1988-06-14
Abstract: The camera (30) consists of an optical system for creating a data record on a photosensitive medium and includes a laser (36) for generating a light beam and mirrors (62, 72, 74 and 82) for transmitting the light beam to a final light beam path (56e) which is rotated about an axis (63) parallel spaced from the final light beam path (56e). Further the camera (30) includes an assembly (38) for shaping and focusing the light beam to have a bar shape cross section which is directed to the rotating final light beam path and imaged onto a photosensitive medium (86). A modulator (58, 60) modulates the light beam from the laser (36) intermittently to image or record light beam bar shape cross sections defining data in an arcuate path (14) on the photosensitive medium (86), a computer (32) controls the modulator (58, 60) and a carriage (88) is provided for moving the photosensitive medium (86) toward and away from the axis (63) about which the final light beam (56e) rotates.

Abstract: METHOD AND APPARATUS FOR CONTROLLING     THE ACTUATION OF GRIPPER ARMS  ABSTRACT OF THE DISCLOSURE     An insertion machine has a plurality of gripper arms (16), each gripper arm including jaw members (24,26) between which inserts are engaged and from which engaged inserts are released in precise placement upon a transport means (18).  Each jaw (26) is actuated by actuating means (28) acting through linkage means (30) to perform the engagement and release operations.  Upon insert engagement the activation of the actuating means (28) is controlled to be dependent upon the operating speed of the insertion machine.  Upon insert release the activation of each actuating means (28) is controlled so that release is delayed by three release time delay components.  A first release time delay component is occasioned by a master presettable release delay means (322) which delays the release operation actuating means (28) of all insert stations in accordance with a preset input value.  A second release time delay component is dependent upon the operating speed of the insertion machine.  A third release time delay component, which varies from insert station to insert station depending on insert size, is occasioned by individual station presettable release delay means (338) which delays the release operation of actuating means (28) for its insert station.

Abstract: INTEGRATED CIRCUIT FILTER WITH         REDUCED DIE AREA  Yusuf A. Haque ABSTRACT       An electronic filter which has particular appli-cation for use as an antialiasing filter in sampled data systems fabricated so as to utilize high resistivity diffused regions (36, 37) within the semiconductor body (31),  as opposed to low resistivity polycrystalline silicon resistors.  Furthermore, the values of the resis-tors and capacitors selected for use in a filter con-structed in accordance with this invention are such that the high resistivity resistors require a small amount of space, and are physically located beneath the capacitors (33, 34, 35) used in the filter of this invention.  The lower plate (33) of the capacitor is connected to a fixed voltage potential, thereby in effect shielding the under-lying resistors from the deleterious effect of changes in voltage, and thus preventing the modulation of the resis-tance values of the resistors.
