Abstract: Abstract of the Disclosure A mixture of air and particles to be classified is ejected through a nozzle located at a lower portion of a vertical housing to deposit the ejected particles on an inner surface of the housing and to convey fine particles by a whirling upward air flow.  Air is ejected radially beneath the nozzle to separate fine particles from the particles deposited on the inner wall to convey upward the separated fine particles by the whirling upward air flow and to cause coarse particles to fall down to the outside of the housing.  A rotating disc with vanes is disposed in an enlarged upper portion of the housing to separate fine particles to cause them to fall down.  The air containing remaining fine particles is conveyed to a cyclon separator to separate the remaining fince particles.  Preferably, the air discharged from the cyclon separator is circulated again through the housing and the cyclon separator.     According to this invention the particles to be classified can be dispersed in the housing without using any independent dispersing device thus simplifying the particle classifying apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE          CONTROL DEVICE FOR A DISPLAY SCREEN AND DISPLAY          SCREEN CONTROLLED BY THIS DEVICE          The invention relates to planar display screens and more particularly to smectic liquid crystal screens.          One of the problems of high definition display screens (approximately 100 to 1000 lines and columns) is caused by the devices for controlling the heating current on the lines. The complexity of the installation and costs limit the increase in the definition. The invention arranges the N lines of a screen into   groups of lines supplied at each of their ends by   control devices functioning sequentially, i.e. 2  devices in all. Moreover, each line has a diode placed between the heating resistor and the common point of the circuit.

Abstract: DEPTHWISE-ORIENTED INTEGRATED CIRCUIT    CAPACITORS AND METHOD OF MAKING   ABSTRACT OF THE DISCLOSURE A depthwise-oriented capacitor comprises a cluster of elon-gated oppositely-doped conductive regions extending depthwise into a semiconductor substrate.   Interspersed p-type and n-type regions form opposite poles of  the capacitor.   The conductive regions are narrow parallel plates or cylindrical columns doped in concentrations suffi-cient  to  establish  metal-like  electric  field  boundary  conditions. Such  regions  are  ion implanted or diffused  into the substrate bulk along a crystallographic channel  thereof to maximize ion penetration. The substrate is either near-intrinsic or semi-insulative so that the semiconductor material between the conductive regions is substantially nonconductive.  The oppositely-doped regions are spaced to deplete the intervening nonconductive region of free carriers over the operational voltage range of the capacitor but not exceed the depleted breakdown voltage  of  such  region.   The  conductive  regions  are  geometrically arranged  in  hexagonal  or  square  honeycomb  patterns,  so  that  the nearest neighbors of each conductive region of one dopant type are of the opposite dopant type.  Link trimmable surface conductors intercon-nect the conductive regions of one dopant type.  The oppositely-doped conductive regions are interconnected either by surface conductors or by doped conductors in the bulk of the substrate.  Capacitance values can be changed during manufacture without mask alterations by control-ling the depth of the conductive regions.

Abstract: ABSTRACT OF THE DISCLOSURE      This disclosure relates to a method and apparatus for welding a root bead in a gap between two relative-ly thick plates by a submerged arc welding process.  An arc is formed by moving the welding electrode parallel to and closely adjacent the gap, and the welding current is alternated between a background current level and a higher or peak current level.  The peak current level is high enough to heat and melt the lands at the bottom of the groove between the two plates, and the background current level is sufficient to deposit filler metal to form the root bead without cracking or burning through the root bead.  After the root bead has been formed, the groove is filled by depositing additional filler metal.

Abstract: Title of the Invention LEAD FRAME WIRE BONDING BY PREHEATING          Abstract of the Disclosure In a method for welding a lead wire or bonding wire from a microcircuit chip mounted on a lead frame to a lead frame finger, the lead frame finger is preheated prior to any substantial electrical or thermal coupling between the lead frame finger and chip.  Intense but controlled energy is applied to the lead frame finger at levels which might otherwise damage the IC chip.  In one embodiment the lead frame finger is preheated to a temperature below the melting point of the metal comprising the lead frame.  Enhanced bonding is thereafter effected by thermocompression bonding or the like. In another embodiment the preheating step comprises melting a portion of the surface of the lead frame finger and forming a molten pool or puddle in the surface.  Bonding of the lead wire is affected by immersing a section of the wire in the molten pool or puddle.  In order to preheat the lead frame finger a controlled pulse train is delivered for arc discharge at the bonding location.  Bonding apparatus and circuitry for performing the method are described.

Abstract: ABSTRACT OF THE DISCLOSURE         A surveillance marker has a semiconductor connected between arms of a dipole antenna, one arm being of non-ferrous conductive material and the other of high permeability low coer-civity material such as permalloy.  Higher coercivity magnetiz-able pieces are disposed adjacent the low coercivity arm, and all is sandwiched between paper or other insulating layers.  The marker is detected by a combination of RF field and low frequency magnetic field generating and receiving units that energize a master alarm only when both units simultaneously detect the marker signals.  Magnetizing the higher coercivity pieces suppresses a signal that would otherwise be reradiated by the marker from the high permeability arm thereby rendering the marker undetectable.
