Abstract: Abstract of the Disclosure A phase locking system for a video tape recorder/player is disclosed in which a freely reproduced video signal (containing a time-base error) from the VTR is phase-locked to a reference signal provided by a time base corrector.  The freely reproduced video signal is coded into a digitized video signal in response to a first clock pulse train, which is produced from the synchronizing signal and/or the color burst signal contained in the freely reproduced video signal.  The digitized signal is supplied through a first delay circuit or directly to a memory having a memory capacity of at least one field of the digitized signal,  A writing of the digitized signal in the first memory is controlled by a write-in address signal, which is pro-duced from the first clock pulse grain and the synchronizing signal by a write-in address signal generator.  The synchronizing signal is supplied through a second delay identical to the first delay in delay time or directly to the write-in address signal generator in response to whether the digitized signal is passed through the first delay.  A selection between passage of the digitized signal and the synchronizing signal through the delay circuits and direct passage of these signals is controlled in response to the phase difference between the synchronizing signals contained in the freely repro-duced signal and the reference signal.  The digitized signal stored in the memory is read out in response to a read-out address signal, which is pro-duced from the reference signal.

Abstract: ABSTRACT Apparatus for applying a lubricating material to an electrically conductive substrate comprising:  first means to divide a supply of lubri-cating material into a spray of particles, to remove from said spray the larger particles whose weight to diameter ratio is such that they will not remain suspended in substantially quiescent atmosphere, and to deliver the remaining finely divided particles for application on at least one side of the substrate;  second means including a housing having at least one opening, to encompass the substrate and to provide a chamber on said at least one side in communication with said first means, and to maintain a substantially quiescent atmosphere of finely divided particles within the chamber; electrode means within the chamber of the second means, spaced from said at least one side of the substrate, and adapted to inhibit the collection of lubricant thereof;  transport means for moving the substrate into and out of said chamber along a path, and voltage means to apply voltage to said elec-trode means of sufficient magnitude to create a charging field to charge and deposit the finely divided particles of lubricating material on said substrate from the substantially quiescent atmosphere within the chamber. The apparatus uniformly dispurses lubricating particles substantially only by electrostatic forces onto the surface of the longitudinally moving substrate. The percentage coverage of the tiny lubricating spheres on the conducting substrate surface is dependent only upon the quantity of such particles migrating into the partitioned enclosure and the relative velocity (and hence dwell time within the enclosure) of the conducting substrate.  The coverage is substantially uniform because of substantially uniform charge/mass ratios provided; because of the controlled uniform supply of the particles across a transverse dimension of the substrate and because the longitudinally parti-tioned non-conducting enclosure prevents non-random movement of the tiny spheres as they enter the partitioned enclosure and prevents any tendency to deposit the charged particles on the enclosure surfaces rather than on the substrate, per se.

Abstract: Abstract An apparatus and method for orienting a substantially flat wafer are described.  The wafer pre-ferably has two flat registration edges of unequal length.  Upon contact of any edge portion of the wafer with a sense means projecting forwardly from one registration surface, air jets are activated to rapidly rotate the wafer one way until the longer of its two registration edges contacts a sense means projecting forwardly from another registration surface. Then air jets are activated to slowly rotate the wafer the opposite way until said longer registration edge contacts another sense means associated with said other registration surface to effect precise registra-tion of the wafer without overshoot as all three sense means are concurrently contacted and activated.  Wafer movement by the jets thereupon terminates and vacuum is applied continuously to hold the wafer in place while the work operation is performed thereon.  Since the wafer is registered solely by contact with the various sense means (and not by contact with the respective registration surfaces), contamination of the wafer by physical contact is minimized.

Title: Solvent stretch process for preparing a microporous  film
Inventor: SOEHNGEN JOHN W
IPC: B29C55/00
Filed: 1980-05-29
Granted: 1982-09-21
Abstract: Abstract of the Disclosure The present invention provides an improvement in a "solvent stretch" process which renders it possible to transverse stretch a micro-porous film prepared from a precursor film which has been previously uni-axially stretched in a direction perpendicular to the intended transverse stretching direction to thereby improve the permeability of the microporous film while also improving the balance of mechanical properties thereof in both directions of stretch.  The improvement lies in uniaxially stretching the precursor film to form a microporous film having a specifically defined permeability as measured by the Gurley test.  The requisite permeability of the uniaxially stretched microporous film is obtained by selecting the poly-mer employed to prepare the precursor film based on certain specifically defined property requirements and by employing specifically defined process conditions during uniaxial stretching.  The uniaxially stretched microporous film having the requisite permeability can then be transverse stretched under certain conditions without the likelihood of developing splits or breaks in the biaxially stretched microporous film.
