Abstract: A synchronizing circuit for a video disc playback device comprises a non-synchronizing system processing a video signal reproduced from a disc, a synchronizing system processing an internal video signal to be superimposed on the video signal reproduced from the disc, a window establishing circuit for establishing a window including an expected timing of a synchronizing signal of the non-synchronizing system and a control circuit for controlling the synchronizing system to synchronize with the non-synchronizing system. If a synchronizing signal from the non-synchronizing system has occurred in the window in the synchronizing system, the expected timing of the synchronizing signal of the non-synchronizing system is used as the synchronizing signal of the synchronizing system even if the actual synchronizing signal of the non-synchronizing system is deviated from the expected timing. The synchronizing circuit may further comprise a circuit for correcting the window when the synchronizing signal of the non-synchronizing system has occurred outside of the window. The synchronizing circuit may further comprise a time base correcting circuit for correcting time base of the reproduced video signal each time track-kick is performed and a time base reference changing circuit for compulsorily changing time base reference of the synchronizing system each time the track-kick is performed.

Abstract: High quality silicon oxide is grown for integrated circuits by oxidizing poly-crystalline silicon under an oxygen gas flow. A diffusion stop layer of thermal silicon nitride is formed on the underlying substrate priorto the deposition of the poly layer to be oxidized. The nitride layer isolates the substrate from diffused oxygen within the poly layer during oxidation, permitting a non-critical, extended oxidation time. Extension of the oxidation period eliminates imperfect or "loose" chemical bonds throughout the oxide layer formed. Corner stress common in trench applications is minimized because the nitride prevents oxidation in the substrate. The oxidation of undoped poly over doped poly proceeds conformally because the nitride layer therebetween inhibits the enhanced oxidation effect of impurities in the doped poly.

Abstract: To permit dimming of a halogen incandescant lamp, or set of lamps connected to an electronic transformer circuit which receives operating voltage from a power network, rectifies the current supply and chops the rectified power to provide high-frequency alternating voltage for transformation to low voltage of the incandesent lamp, a non-current compensated choke having an inductance of at least 50 mH is connected in series between the rectifier output terminals and the rectifier system terminals, an oscillation start acceleration circuit including a CR circuit is connected in parallel with the starting circuit for the alternately operating transistors and a pair of symmetry resistors (R6,R7) are connected in parallel to symmetry defining capacitors (C6,C7), connected across the rectifier output terminals and a mid-point (M) of the oscillation transistors. The arrangement permits soft starting of the transistors, even if a serially connected phase controlled dimmer circuit suddenly connects line voltage at peak value across the rectifier, while providing for continuous energy release, even if the dimmer control is turned beyond the 90 DEG  phase angle position and, for example, to 135 DEG phase angle.

Abstract: A flexible multilayer label adapted for application to de­formable thermoplastic packages, with such label being impervious to water and sufficiently resilient to avoid permanent deformation upon deflection. The label includes a thermoplastic stress-­compensating stratum (30) having a relatively elastic structure and a lower surface adapted to be bonded to the outer surface of the thermoplastic package during in-mold labeling procedures. The label further includes a thermoplastic label stratum (14) having a Young's Modulus which exceeds about 7030 Kg/cm² and a smooth label surface. The label stratum is laminated to the upper surface of the stress-compensating stratum. The stress-­compensating stratum structure accommodates the thermal stresses and package shrinkage inherent in such in-mold labeling procedures, as well as stresses imposed by deformation of the package in use. As a result of such accommodating capabilities, the label surface of the label stratum is effectively isolated from such stresses and shrinkage and remains substantially smooth, and the laminated bonds between the label stratum, the stress-­compensating stratum, and the deformable package remain substantially intact.

Abstract: A voltage-controlled current source produces two output current signals whose difference Is linearly related to an input voltage signal. The source includes an input buffer and a reference buffer each coupled separately to a current mirror and also coupled together across a current transmitting resistor. In response to the input voltage signal and current transmitted between the buffers, the current mirrors produce currents that differ in proportion to the difference between the input and reference voltage signals. The current mirrors also reproduce the differing currents in output paths as the output current signals. A fixed current source is coupled to each output path for drawing a fixed current from each path to linearize the current difference.

Abstract: An all-fiber ring laser has a single, uninterrupted length of single-mode optical fiber (100) that is formed into a loop (104) by using an optical coupler (110). Pump signal pulses (114) at a first optical wavelength are introduced into one end (102) of the optical fiber (100). Each pump pulse (114) propagates through the loop (104) formed in the fiber (100) and then exits the fiber (100). The pump signal pulses (114) excite the molecules of the optical fiber (100) to cause them to go to a higher, unstable energy level. When the molecules return to a lower energy level, photons are emitted at a second optical frequency that has a wavelength that is shifted from the wavelength of the pump signal to form laser signal pulses. The coupler (110) is a multiplexing coupler (110) that has a first coupling ratio (η p ) at the wavelength of the pump signal and has a second coupling ratio (η s ) at the wavelength of the emitted optical signal. The first coupling ratio (η p ) is preferably close to zero and the second coupling ratio (η s ) is greater than 0.5. The laser optical signal recirculates in the loop (104) to stimulate further emission of optical energy at the shifted wavelength in phase with the recirculating optical signal. Each pump pulse is timed to enter the optical fiber loop (104) in synchronism with the recirculating laser signal pulse so as to excite the fiber molecules so as to amplify the recirculating signal pulses. The laser signal has a loop transit time related to the time interval (T) between pump pulses such that a multiple of the loop transit time is substantially equal to a multiple of the time interval (T).

Abstract: A transmit/receive antenna array network for use in a radar system comprises hybrid means (HY) for applying equal amplitude anti-phase components of a microwave transmit signal to respective parts of an antenna array (AN) having power divider (PA, PB) and phase shifting arrangements (PS) associated therewith. The phase shifting means are appropriately switched for a signal transmission operation to provide not only the requisite beam angle and power tapering but to compensate for the phase displacement between the transmit signal components received from the hybrid means, and the phase shifting means is appropriately switched following the signal transmission operation but before an echo signal receive operation so that received or echo signals are brought into equi-phase before being fed to the hybrid means which provides a "sum" output for processing and display whilst providing complete isolation between the received signals and the transmitter output.

Abstract: A circuit is described in which the bandwidth of the track circuit receiver (8) is design to be so narrow that it is virtually impossible for it to be subjected to interference. To permit interpretation of the frequency-modulated track voltage, the frequency deviation of which far exceeds the bandwidth of the receiver, the narrow band characteristic is achieved by means of an adjustable bandpass filter (7), the centre frequency of which is controlled so that it precisely follows the frequency of the track circuit transmitter (2). For this purpose, the output signal from the track circuit transmitter is fed to the track circuit receiver via a special lead (9). <IMAGE>

Abstract: Excellent stabilization of pigmented polypropylene (PP) fiber against gas fade upon exposure to atmospheric pollutants is obtained with a hindered amine containing a polysubstituted piperazin-2-one (PSP) moiety, for example, a C₂-C₁₂ alkylene connecting two PSP moieties, or a trisubstituted triazine ring with three PSP substituents, or a polyalkylene polyamine having pendant substituted oxo-piperazinyl-triazine moieties (PIP-T), that is, having pendant triazine rings substituted with PSP substituents. The stabilizers are unexpectedly effective when used with­out an antioxidant which produces yellowing, if used. Either pigmented or unpigmented PSP-stabilized PP fibers, and particularly fibers pigmented with white or pastel dyes, and having a non-alkaline "finish" are especially benefit­ted. Fibers made from PP stabilized with such a hindered amine, but lacking conventional antioxidants, have improv­ed gas fade resistance, compared to fibers made from PP stabilized with several other commercially available hind­ered amines tested, including those which contain hetero­cyclic amines which are not PSPs, and especially those amines containing a hindered phenol moiety.
