Title: Lint remover
Inventor: MCKAY NICHOLAS D
IPC: C09J7/02
Filed: 1989-06-12
Granted: 1993-10-12
Abstract: ABSTRACT           A lint remover assembly is provided having a handle member which has a lint remover roller in association therewith.          The roller is adapted to supportably receive a pressure sensitive adhesive tape roll thereon which has layers of adhesive tape with the adhesive surface facing outwardly to that the adhesive tape roll can be selectively rolled over a surface to selectively lift lint and/or other foreign particles therefrom.  The combination described comprises a pressure sensitive adhesive tape roll which has an outwardly facing adhesive surface adapted for selective mounting  upon  a  lint remover roller.   The pressure sensitive adhesive  tape  roll  has  at  least  one  slit  substantially therethrough which extends only partially across the width of the tape roll so as to define a narrow unslit portion in the tape roll  which  maintains  the  retentive  longitudinally  continuous integrity of the tape roll on the lint remover roller upon which it  is mounted.   Each  layer  of the tape roll thereby becomes selectively detachable upon saturation by lifting it away along the slit and tearing it away through the narrow unslit portions to expose the next lowermost unused layer.

Abstract: SEMICONDUCTOR DEVICES HAVING CLOSELY SPACED DEVICE REGIONS FORMED USING A SELF ALIGNING      REVERSE IMAGE FABRICATION PROCESS                  ABSTRACT OF THE INVENTION       A method of forming a semiconductor device on a body of semiconductor material having a first doped region of a first conductivity type, comprising the steps of: forming a stud over the first doped region; using the stud as a mask to form a second doped region of a second conductivity type in the surface of the first doped region adjoining the stud; forming a sidewall of insulating material on the stud; forming a first device contact within the sidewall; and forming a second device contact over the second doped region adjoining the sidewall, such that the first and second electrical contacts are separated by the sidewall.      In accordance with an embodiment of the present invention, the step of forming the second device contact includes the steps of forming a layer of conductive material generally conformally over the first doped region and the stud, and then planarizing the layer of conductive material to a height equal to or less than that of the sidewalls.  The second contact is thus self-aligned with the first and second doped regions and the first device contact.  The method of the present invention can be utilized to fabricate bipolar transistors, insulated gate transistors, and BICMOS logic including both types of transistors.  It can further be used to fabricate any other type of semiconductor device which utilizes the self-aligned, closely spaced device regions and contacts of the present invention.

Abstract: The invention concerns an ion exchange process and system, particularly for the regeneration step following a softening or desalination of aqueous solutions. The regenerant solution is fed in an upward stream through the ion exchanger in a direction opposite to the charging direction, as a sequence of intermittent pulse intervals consisting of pulse flow followed by a period of no flow. During the pulse flow, there is limited hydrodynamic lifting of the ion exchange resin beds in layers, followed by subsequent sedimentation during the pause period, without mixing of the layers.

Title: Method of color selection for display and printing
Inventor: PAXTON WILLIAM H
IPC: G06F3/153
Filed: 1989-08-31
Granted: 1993-04-20
Abstract: ABSTRACT        The invention provides a method for selecting the intensity level of each of the primary colors for displaying or printing a predetermined, desired color to be composed of a specified percent of each of the primary colors.  Each primary color has available a predetermined number of discrete intensity levels ranging from minimum to maximum and is to be displayed on a matrix having a predetermined number of cells.          The first step in the method is to determine a desired intensity level for each primary color and to select the number of cells of the matrix which are to display that color at that intensity level.  These cells of each primary color are then arranged in the matrix in a predetermined ordering to display the desired color.  The sequence of the ordering is predetermined and the same for each primary color.  The starting point of the sequence for one of the primary colors is fixed, but the starting point for each successive primary color is dependent upon the ending cell location of the sequence of cells for the preceeding color.  Using the invention, the amount of color memory required is reduced because the number of storage cells required for storage of color selection information need only be equal to the product of the numbers of available intensity levels for each primary color.

Abstract: A cellular radio system in which the mobile radio stations in the zone of any base radio station assign themselves to the control channels allocated to that base station so as to evenly spread the volume of traffic over such control channels. The base station transmits on each control channel a channel group code signifying the range of group code numbers allocated to that particular control channel. Each mobile station stores its identifying group code number, scans the group code numbers of all control channels, and assigns itself to the control channel having a channel group code which includes its group code number. The spread of traffic over the various control channels can be changed by the base radio station simply by changing the channel group codes of the various control channels, without addressing specific commands to the mobile radio station.

Abstract: The composite laminate is made of two metal parts 1, 2 and a pair of thermal insulating bars of fiber reinforced synthetic material. Each metal part has a longitudinally extending groove which is provided with two rows of transversely disposed teeth which cut into the flanks of anchoring strips on the synthetic bars during pressing in of the strips in the respective grooves. The pressing in of the synthetic material into the teeth of the harder metal parts forms a strong bonded connection which resists the stresses imposed upon the laminate during use. Deformable tabs on the metal parts are used to ensure locking of the synthetic bars in place. The space required for production of the laminate is reduced essentially to the length of the metal parts.

Abstract: The energy of a laser beam (32) is used to form images at intervals along a lengthwise moving web (10). The images are formed along a plurality of axes spaced transversely of the web so that after slitting and cutting an image appears on each sheet. The laser beam (32) is directed across the web and is repetitively and successively switched by rotating optical mirrors in assemblies (71a-71g, 72a-72g) located at intervals across the web to scan image-bearing masks (Fig. 2) rotating with the mirrors. The beam impinges on respective mirrors of successive assemblies. The mirror assemblies are conical mirror segments (78) of plane mirrors cooperating with a fixed conical mirror segment (Fig. 5) to produce a focussed line (82) that is fixed in space and scans the rotating mask. The scanning line is re-imaged (90) on the web (10).

Abstract: PCT No. PCT/CH84/00082 Sec. 371 Date Oct. 22, 1985 Sec. 102(e) Date Oct. 22, 1985 PCT Filed May 23, 1984 PCT Pub. No. WO85/03732 PCT Pub. Date Aug. 29, 1985.Electrical conductors wound into coils (4, 5) are disposed in a housing (1). The axes of the coils (4, 5) run perpendicular to the base of the housing. Each coil (4, 5) is connected with a capacitor (2, 3) so that oscillatory circuits are formed. The longitudinal axes (10, 11) of the capacitors (2, 3) cross the coil axes at right angles and consequently run parallel to the base of the housing. In one (4) of the coils (4, 5) a permanent magnet (6) is inserted. Each coil has its own number of windings, its own outer diameter (15, 16), and advantageously its own inside diameter (18, 19). The oscillatory circuits are closed or opened by a switch (12). The oscillatory circuits are excited by the interfering fields present and generate in their turn a counter field. The process conforms essentially to the Lenz law of physics, according to which the reaction produced in the apparatus counteracts, and in the ideal case eliminates, the stimulating field action which produces it. As a result, the water in the capillary of the walling can no longer rise and the walling dries out in natural ways.
