Abstract: ABSTRACT:           A polar loop transmitter having particular, but not exclusive, application in VHF single-sideband radio systems.  In order to avoid having to match the amplitude detectors used in known polar loop transmitters, it is proposed as an alternative to provide a subtracting cir-cuit which produces a difference signal from between the low level input signal and the attenuated output signal. The difference signal is amplitude demodulated in a mixer and the demodulated signal is used as a control signal for the amplitude modulator.  First and second limiting ampli-fiers are used to derive the carrier signals from the input and output signals.  The outputs of the limiting amplifiers are applied to a phase sensitive detector formed by another mixer whose output is used as a correc-tion signal for a voltage controlled oscillator coupled to the amplitude modulator.  The output of the first limiting amplifier is also used as the local oscillator signal for the amplitude demodulator.  Means are proposed for com-pensating for the phase shifts introduced by the limiting amplifiers.

Abstract: THREE DIMENSIONAL DIGITIZER WITH ELECTROMAGNETIC COUPLING   ABSTRACT OF THE DISCLOSURE A three dimensional digitizer is provided for determining and digitizing the coordinates of a three dimensional object.  A hand-held stylus is used for tracing and determining points of interest on the surface of the object.  A plurality of antennas for radiating electromagnetic energy are provided, the antennas being embedded in a table having a work surface upon which the object is placed.  The radiating antennas have independent components which define a reference coordinate frame.  A transmitter applies electrical signals to the radiating antennas which generate a plurality of distinguishable radio frequency electromagnetic fields.  The stylus is provided with a projection for defining a point of contact between the stylus and the surface of the object of interest.  A plurality of receiving antennas are disposed in the stylus.  The receiving antennas have a known relationship with the projection and the point of contact on the object. The receiving antennas are provided with a plurality of independent components for detecting each of the transmitted electromagnetic fields.  The output of the receiving antennas is supplied to an analyzer which converts the components of the electromagnetic fields received by the receiving antennas into the remote position and orientation of the receiving antennas relative to the reference coordinate frame.  Since the point of contact of the stylus and the receiving antennas are provided with a known relationship, the coordinates of the surface of the three dimensional object touched by the stylus are also determined in the analyzer.

Abstract: In the high voltage d-c transmission (HGU) power station in a block circuit, a three-phase generator feeds a 12-pulse high voltage d-c transmission (HGU) short coupler through at least one shifting transformer which serves for forming voltages of two three-phase voltage systems phase-shifted relative to each other by 30.degree. el. As compared to a full transformer, the shifting transformer can be constructed for substantially less power, which reduces the cost and the losses of the station, While the voltages of the two phase-shifted voltage systems can be taken off at the external terminals of the secondary windings of the shifting transformer, the center taps of the secondary windings are acted upon by the generator voltage. Advantageously, the high voltage d-c transmission short coupler is formed of a multiplicity of parallel, electrically separate d-c circuits which can be fed by separate shifting transformers.

Abstract: A process for bonding together two or more pieces of material, at least one of which is an amor-phous material, wherein an intermediate interlayer is placed between the two pieces and the assembly is hot pressed at a temperature above the melting point of the interlayer but below the crystallization temperature of the amorphous piece. The composition of the interlayer is chosen so that the elements diffusing into the pieces being bonded are compatible with retention of the amorphous structure. When the bonding operation is carried to completion, no evidence of the interlayer as a separate phase remains. Alternatively, the bonding operation may be halted before completion and the interlayer will remain as a separate, observable phase:      For bonding hard metal amorphous materials, alloys of aluminum with silver, gold, silicon and germanium, and alloys of gold with silicon, with the addition of flux-ing elements such as phosphorus and boron, have been found to provide particularly satisfactory results.

Abstract: PRE-PATTERNED DEVICE SUBSTRATE DEVICE-ATTACH ADHESIVE TRANSFER SYSTEM            Abstract of the Disclosure A pre-patterned device substrate device-attach transfer tape is described which allows a one step mounting of adhesive patterns on a device substrate in the desired configuration for later mount of surface mounted devices (e.g., semiconductor dies) thereon. The tape product contains the adhesive pattern in a mirror image to that desired on the exposed surface of the device substrate.  The product of the present invention is utilized by bringing the tape product into contact with the device substrate so that the adhesive on the carrier film bonds to the desired surface of the device substrate thereby bringing the adhesive patterns into the desired configuration desired on the device substrate.  The use of pressure and, possibly, heat preferentially bonds the adhesive to the device substrate and allows for later stripping of the support film from the support film/adhesive/ device substrate composite.  This step leaves behind the desired adhesive configuration on the device sub-strate and allows for later bonding of appropriate surface mounted devices to the device substrate.                      * * * * * *

The center unit includes a receiver for receiving the modulated digital signal, a PN code generator for locally generating a PN code which corresponds to the transmitted PN code, a multiplier sup-plied with outputs of the receiver and the PN code generator to produce a digital signal de-spread from the PN code, a demodulator connected to the multiplier to reproduce the digital data from the modulated digital signal, and a memory for storing the PN code when the signal level of the multi-plier exceeds a predetermined value.  The stored PN code is retrieved from the memory to enable rapid synchronization with the next transmission received from the terminal unit.

Abstract: ABSTRACT OF THE DISCLOSURE      An optical head for an optical signal recorder includes a nonpolarizing beam combiner for combining the light beams from two like-frequency, sic wavelength, lasers along one light path.  The combined beams travel slightly diverging paths so that a first one of the beams can record signals on a disk while a second beam follows the first beam on the disk for direct reading-after-recording.  Intermediate the combiner and the disk are a polarization type beam splitter and a focuser.  One or more detectors receive reflected light from the disk via the beam splitter for detecting focus, sensed recorded signals and for tracking the beams to tracks or the disk.  The combiner and splitter are prefera-bly secured together as a single unit.  The combiner uses refraction and internal reflection properties to combine the two like-frequency beams without polarization changes of either beam.
