Abstract: ABSTRACT           Magnetron Sputter Coating Source for Both Magnetic and Nonmagnetic Target Materials A novel magnetron sputter coating source is disclosed in which magnetic sputter targets containing relatively large inventories of usable material may be employed.  This coating source may also be used efficiently and effectively with sputter target materials having proerties which range from nonmagnetic to highly ferromagnetic.  Use of an electromagnetic coil with a widely adjustable energizing current, rather than permanent magnets, allows a wide range of magnetic properties to be accommodated.  Electrical impedance of the glow discharge is readily controlled using the current flow through the electromagntic coil, allowing, for example, operation at desired values of voltage and current throughout the life of the sputter target.  In addition, a momentary increase in electromagnet coil current can be used to achieve ignition of the glow discharge at a desired sputter gas operating pressure which is below the sputter gas pressure at which the glow discharge can normally be readily ignited.  Also, use of the electromagnetic coil permits an easy conversion of the magnetron sputter coating source to a nonmagnetic diode apparatus.  The use of a Hall probe positioned adjacent and below the sputter target near the region of maximum erosion is disclosed.  The Hall probe voltage, which is proportional to the magnetic field intensity at the Hall probe position, may be measured throughout sputter target life to provide an independent means of assessing the approach to end of useful life.  A novel sputter target cooling means is disclosed in which a water chamber below the sputter target is divided into inlet and outlet portions by a septum.  The flow of water through a narrow gap between the septum and the sputter target leads to highly effective heat transfer, which is also highly uniform along the peripheral path of intense heating of the sputter target.

Abstract: Abstract of the Disclosure The present invention is an improvement in a method of screening a line screen slit mask color picture tube.  Such method includes coating a faceplate panel of the tube with a photosensitive material, inserting a slit shadow mask into the panel, and exposing the photosensi-tive material by passing light from a line light source through the slits of the mask.  The improvement comprises positioning a generally cylindrical shaped lens between the line light source and the faceplate panel during exposure of the photosensitive material.  The longitudinal axis of the lens is oriented perpendicular to the longitudinal axis of the line light source.  Because of the presence of the lens, the images of the line light source projected through the slits of the mask onto the photosensitive material, at locations off the major and minor axes of the panel, are rotated toward parallelism with the minor axis, thereby resulting in exposure of straight smooth lines on the photosensitive material.

Abstract: ABSTRACT        A mobile radio communications system for wide area mobile radio communications allows any two remote mobile stations to hold communications by way of a public switching network.  A fixed station governing an area in which a calling mobile station is located sends to a switching network its own identification (ID) data and ID data associated with a mobile station which is connected to the fixed station by radio.  Based on the two kinds of ID data, a called mobile station sees a telephone number assigned to the calling mobile station and a telephone number assigned to the fixed station which is associated with the call-in mobile station.

Schweitzer, Jr.               Abstract of the Disclosure A detector for indicating loss of voltage on a monitored conductor includes first and second serially connected capacitors, and a rectifier circuit which derives operating power from the monitored conductor to charge the capacitors in the presence of voltage on the conductor.  A forward-biased diode connected across the second capacitor limits the voltage developed across the second capacitor during charging to a relatively low level.  Upon loss of voltage a portion of the charge in the first capacitor is transferred to the second capacitor, causing the voltage across the second capacitor to reverse polarity and progressively increase.  This causes an enhanced field effect transistor connected across the capacitor to become conductive and discharge the first capacitor through a relay or other indicating device to provide a control effect indicative of voltage loss.
