Abstract: ABSTRACT      Fine particles,  of predetermined composition and sized to be within a predetermined size range, are deposited  on,  and  thereafter  adhere  in random distribution to, one of two adjacent surfaces, serving to keep the surfaces uniformly spaced apart except when an external force causes them to make local contact. The particles are conveniently applied in the form of a spray of a suspension of particles and a fluid carrier material, preferably water with alumina particles, or an aqueous solution of a chloride salt of an alkaline earth metal such as calcium, potassium or sodium when small glass beads are used as the particles.  Brown alumina particles (approximately 96% A1203) in the size range 3-50 microns, so utilized, are found well suited as parallel surface spacers in optically transparent touch sensitive overlay  (TSO) panels.   Particle distribution densities in the range 300-1,000 particles per inch are satisfactory for TSO panels, with the higher particle density requiring a higher actuation pressure to be applied.

Granted: 1992-03-10
Abstract: ABSTRACT OF THE DISCLOSURE          A transparent article comprising a transparent base, at least four coated layers, and a top protective layer is disclosed. The coated layers include a first dereflecting region, a transparent layer of silver or other metal, and a second dereflecting region comprising a layer of titanium dioxide and a layer of another dielectric material. A titanium dioxide layer may also be a component of the first dereflecting region. Each dereflecting region that includes a titanium dioxide layer also comprises a layer of a transparent oxide or other dielectric material having an index of refraction intermediate between about 2.7 the approximate index or titanium divide, and the index of the nearby base or top layer, respectively. The intermediate index material is preferably zinc oxide because this material can be relatively quickly and inexpensively deposited by reactive  quickly. Also disclosed is a method for depositing the coated layers by sputtering and reactive  puttering of titanium and silver, zinc or other materials. The coating is useful as a component of a laminated window, particularly on electrically heated windshields for automobiles.

Title: Pulse-width modulator
Inventor: RIEDGER THOMAS
IPC: H03K7/08
Filed: 1987-06-04
Granted: 1991-11-05
Abstract: ABSTRACT:         The pulse-width modulator described herein comprises a square-wave generator, a retriggerable monostable multivibrator, a gate circuit and a controllable current source, having a capacitor as a timing element for the multivibrator.  If the modulator is assembled from standard building blocks in CMOS-technology and several external components, its power dissipation will remain below 10 mW.  If completed by a variable-gain amplifier - likewise carried out in CMOS-technology - and a reference voltage source, the pulse width modulator can be advantageously used in the control circuit of a clocked direct voltage converter.  Then the internal losses of a direct voltage converter constructed thus will still remain below 25 mW.

Abstract: ORTHOGONAL MODE ELECTROMAGNETIC WAVE LAUNCHER     ABSTRACT            A launcher (20) of cross-polarized electromagnetic radiation is provided with increased bandwidth by inserting a set of axially directed ridges (50-56) on the interior surfaces of waveguide walls (28-34) of the launcher (20) for concentrating electric fields of radiations of the different polarizations.  A first radiation radiated by a probe (62) in a back section (68) of the launcher waveguide (26) propagates forward into a front section (66) of the launcher waveguide (26).  A second radiation is radiated into the front section (66) by a probe (64) therein, there being a vane (58) disposed in the front section (26) for inhibiting the propagation of the second radiation into the back section (68).  The front section (66) is flared to provide a larger exit aperture at a front end of the front section (66).

Abstract: The invention relates to a method and apparatus for sand molding composite articles formed of a light alloy metal and fibrous insert. A sand mold is formed containing a fibrous preform separated from the walls of the mold cavity. The mold is fed by means of a tube dipping into a liquid metallic bath therebelow. In the molding process, the pressure in the mold cavity and above the bath are reduced, and the pressure above the bath is increased to create a positive pressure differential  DELTA P, thereby forcing molten metal from the bath into the mold cavity. The pressure in the mold cavity and above the bath are then increased to above atmospheric, and the pressure differential  DELTA P is maintained until the metal in the mold cavity solidifies.

Granted: 1992-06-09
Abstract: Abstract Of The Disclosure A register management system has more physical registers for general purpose use than are named in the architectural system.  A renaming system identifies particular physical registers to perform as architected addressable or general purpose registers.  An array control list (ACL) is provided to monitor the assignment and status of the physical registers.  A decode register assignment list (DRAL) is provided to monitor the status of all of the architected registers and the correspondence to physical registers.  A back-up register assignment list (BRAL) is used to preserve old status information while out of sequence and conditional branch instructions are executed.  The physical registers may retain multiple copies of individual addressable registers representing the contents at different stages of execution.  The addressable register status may be restored if instruction execution is out of sequence or on a conditional branch causing a problem requiring restoration.  The register management system may be used in a processor having multiple execution units of different types.
