Abstract: MEMORY CIRCUIT     ABSTRACT OF THE DISCLOSURE      A memory circuit comprises a semiconductor element circuit having equivalently a PNPN four-layer structure, at least an NPN transistor and a diode. An N-type emitter of the semiconductor element cir-cuit is connected to the base of the NPN transistor, while a P-type base of the circuit is connected to the collector of the NPN transistor through the diode. The semiconductor element circuit has a positive feedback loop which is additionally provided with another feedback loop extending across the P-type base and the N-type emitter of the semiconductor element circuit, whereby in the ON holding state of the memory circuit the semiconductor element circuit is operated as a current stabilizing circuit and the transistor included in the additional feedback loop is stabilized in a controlled staturation state.  The memory circuit can thus be operated at a high speed with a low power consumption.

Abstract: HIGH DENSITY ARCHITECTURE FOR A SEMICONDUCTOR CHIP                    Abstract A semiconductor chip layout including a plurality of logic cells arranged in columns.  A cell may encompass one of two different magni-tudes of area in the chip; and each column contains only cells having the same area.  The layout is particularly appropriate for level sensi-tive logic systems which utilize both combinatorial as well as sequen-tial networks.  The combinatorial (combinational) networks are less orderly and require a greater number of selectable input connections, hence more area, than the sequential circuits.  The wide and narrow columnar architecture allows a much greater circuit packing density on a chip, resulting in a substantial increase in the number of circuits for a given chip area.  Performance is also increased because of the reduced area required by the sequential circuits.

Abstract: IMPREGNATION AND PRIMER COATING OF ABSORPTIVE SUBSTRATES           WITH PLASTICS DISPERSIONS           Abstract of the disclosure: Absorptive substrates, such as asbestos cement, concrete plaster work, can be impregnated to lock the pores  and to so-lidify the substrate, especially old and weathered plaster work , with aqueous plastics dispersions, if dispersions are used which have an average particle size of about 0.02 to at most 0.1µm, and preferably from 0.02 to 0.06 µm.  As opposed to con-ventional dispersions with larger particle sizes, the penetra-tion of dispersions according to the invention reaches the same values as that of the solvent-based impregnating and priming compositions hitherto used.  Aqueous dispersions are easier to handle and permit relatively high solids contents at a moderate vis-cosity.

Abstract: Abstract of the Disclosure A process for providing a dried textile yarn, glass fiber yarn in particular, is described in which a wet textile strand is passed through a zone of high fluid turbulence, a heating zone and wound rapidly on a spool.  In the process as applied to glass fiber yarns, finished textile strands are provided on spools which are con-siderably larger than the finished bobbins normally used by textile weavers.  The yarns are dried directly from the wet forming packages to a completely dried state thus eliminating the binder migration problems frequently encountered in the drying of fiber glass on forming packages.

Abstract: DIGITAL SYNCHRONIZING SIGNAL RECOVERY      CIRCUITS FOR A DATA RECEIVER     Abstract of the Disclosure A data signal stream includes, in a noisy signal channel, periodic word synchronization characters, and each such stream is preceded by a burst of predetermined bit rate information. An approximate bit rate timing signal is derived from the data stream and utilized for producing an initialization pulse when the predetermined bit rate information is detected.  In addition, the approximate bit rate timing signal drives a digital phase-locked loop which is preset by the initialization pulse to a digital circuit state defining operation at the nominal frequency of the approximate bit rate timing signal.  A stable bit clock signal provided by the phase-locked loop controls the operation of further circuits which are responsive to the baseband data stream for providing an indicator pulse each time that a synchronizing character appears in the data stream.  The bit rate clock and the character indicator pulses are employed to operate a timing chain that yields word synchronization pulses in synchronism with the indicator pulses and having an extraordinarily low false-pulse rate as well as evidencing a flywheel effect to maintain word synchronization in the event that a small number of character indicating pulses are missed.  If more such pulses are missed, the timing chain is resynchronized.     - i -

Abstract: Abstract of the Disclosure A sensing device is provided for the detection of electromagnetic radiation through the use of a large area (i.e. 1 sq. cm and larger) pyroelectric/piezoelectric sensing medium.  The detection operation of the sensing device is constructed to ignore spurious detection indications due to bending or compression of the sensing medium.  In a preferred embodiment the sensing device is formed from a two housing construction that includes outer and inner housings.  The outer housing of the device includes an infrared transmissive window at one end.  To substantially physically isolate the two housings from one another, the inner housing of the device is supported inside the outer housing by means of support members protruding through the opposite end of the outer housing.  The sensing medium is dis-posed in one end of the inner housing and is protected by the outer housing from bending or compressive stress.  Also, a rigid low thermal conductive material may be adhered to one side of the sensing medium to reduce low frequency mechanical and acoustical vibration of the medium without substan-tially reducing the sensitivity of the device and thereby gain signal to noise ratio improvement.

The bulb housing is generally in the shape of a modified cube elongated in one direction.  The housing has four substantially same size rectangular sidewalls extending between substantially square head and tail endwalls.  One of the sidewalls is imperforate and serves as a mounting base.  The other three sidewalls have windows of heavy, heat-resistant, transparent glass-like or ceramic material.  The head endwall has a pair of glands including flanged, threaded bushings to seal electrical power conductors extending through it.  The flanges of the bushing have wrench-engageable flats.  The endwalls have a pair of axially aligned, screw-threaded openings of identical thread diameter and pitch.  Screw-threaded head and tail cover members are threadedly engageable within these openings.  A bulb socket member and a grounding lug are mounted on the inside surface of the head cover member, all being removable as a unit by unscrewing the head cover member.  There is a central boss with wrench-engageable flats on the outside surface of the head cover member.  A locking plate simultaneously engages flats on the gland bushings, and on the boss, to prevent loosening.  A screw-threaded inspection plug in one of the sidewalls provides access to the grounding lug.  The entire bulb housing is pro-tected within a cage-like outer guard assembly.  Different shaped reflector means between the bulb and housing direct the light through one or more selected side windows, in addition to an end window in the tail cover member.
