摘要： A deposition furnace boat includes a plurality of wells each of which is adapted to contain a solution of the material to be deposited. A slide extends across the bottoms of the wells and is adapted to carry a substrate from one well to the next. Between each pair of adjacent wells is a narrow slot extending to the surface of the slide. Epitaxial layers are deposited on the substrate by moving the slide to bring the substrate into each well in succession. While the substrate is in each well, the solution is cooled to deposit the material from the solution onto the substrate. When the slide is moved to carry the substrate from one well to the next, the substrate passes beneath the slot which is between the wells. Any of the solution which may be carried with the substrate from the one well will be drawn up into the slot by capillary action so as to prevent contamination of the solution in the next well by any carry-over solution.

摘要： A disc type record player incorporates apparatus for preventing more than one record disc from being disposed in operative position on a turntable at any one time. Movable members associated with a turntable spindle are operatively repositioned in response to passing a first record disc over the spindle and onto the turntable. The repositioned members inhibit passage of a further record disc over the spindle. Player operation is inhibited when a sensing means detects the presence of a further record on the spindle.

摘要： Stacked transistor power amplifier stages in an integratedcircuit quasi-linear amplifier are supplied quiescent bias currents which are in inverse proportion to their forward current gains. This permits selection of their quiescent collector currents to be at sufficiently low levels to reduce to low values both cross-over distortion and quiescent dissipation.

摘要： Bias for the n cascade connected output transistors of a conventional series amplifier is obtained by applying successive increments, each 1/n times the output voltage available across the series connected conduction paths of these transistors to the control electrodes of the successive transistors in the cascade, except for the one connected to the load terminal. Drive signal is applied to the control electrode of this transistor. In accordance with the present invention, the drive signal is supplied via n cascade connected input transistors biased in similar fashion to the cascade connected output transistors, to develop across its conduction path a voltage approximately equal to 1/n times the amplifier output voltage. This way of applying drive signal to the series amplifier facilitates its connection with another series amplifier in push-pull amplifier configurations.

摘要： A semiconductor P-N junction voltage source temperature compensating network comprises a resistor coupled in parallel with a resistor and a semiconductor P-N junction device in series. The parallel combination is coupled across the terminals of a semiconductor P-N junction voltage source. The source voltage varies with temperature and current according to the diode equations. The voltage across the series coupled P-N junction device varies in the same manner, decreasing with increasing temperature over a substantial range of operating temperature so that the effective resistance of the series combination decreases in substantially direct proportion to the source voltage. Thus if the resistors in the parallel circuit are chosen according to a specific ratio a substantially constant current relatively independent of temperature over a broad range of operating temperature can be made to flow through the parallel combination.

摘要： In a horizontal deflection and high voltage generating circuit in a television receiver, the high voltage is regulated to remain substantially constant with variations in picture tube beam current variation and receiver direct current power supply variation. A high voltage variation representative signal is coupled to a regulator circuit including a saturable reactor magnetically biased such that a failure comprising either a short or open circuit in the regulator circuit causes the input energy to the deflection circuit not to increase beyond a predetermined amount.

摘要： Information signals are redundantly processed by an apparatus which utilizes two channels, each channel having at least one shift register. A first block of information signals is loaded into one shift register at one clock rate. It is then read out and re-loaded into the same shift register at a second higher clock rate. It is then read out a second time at the higher clock rate. A second block of information signals is similarly processed in the corresponding shift register in the other channel in an offset time interval with respect to the operation of the first shift register. The apparatus provides first and second representations of the information signals processed by the shift registers so that first and second representations of the first block of information signals followed by first and second representations of the second block of information signals may be, for example, recorded, in the order named, in a single track of a record medium. Thus, if an imperfection exists in the first block of data, data can be recovered from the second block.

摘要： A method is disclosed for conditioning transmission lines for a desired response. The method utilizes pre-recorded test signals transmitted over the unequalized transmission line. The response of the unequalized line to the test signal is recorded. The recorded response is then played through an adjustable equalizer off-line and the equalizer is adjusted for a particular response. The equalizer is then inserted in the transmission line.
