Abstract: A method of forming a multitude of vertical NAND memory cells, includes, in part, forming a multitude of insulating materials on a silicon substrate, forming a trench in the insulating materials to expose a surface of the silicon substrate, depositing a layer of polysilicon along the sidewalls of the trench, filling the trench with oxide, forming a metal layer above the trench, and forming a mono-crystalline channel for the NAND memory cells by applying a voltage between the silicon substrate and the metal layer to cause the polysilicon sidewalls to melt. The melted polysilicon sidewalls is enable to recrystallize into the mono-crystalline channel.

Abstract: A “cross-eye” type radar countermeasure in which both of the waveforms of the illuminating signal from the enemy radar received at spaced locations on the carrying vehicle is propagated through a common dual channel to balance the effect of unintentional phase distortion. Two common channels receive the radar waveform and store the same in a delay line. During the stored interval the switches at the ends of the two common channels are transitioned to the non-stable state connecting the output end of one common channel to the input end of the other, and vice versa. Both waveforms then enter the delay line of the subsequent common channel and the switches change to the stable state whereupon each waveform is retransmitted at the other spaced location on the carrying vehicle.

Abstract: An automatic adaptive sensitivity time control for a ground mapping radar comprises the dynamic range of radar returns for presentation on a video display. A feedback loop including a differential amplifier senses the magnitude of a signal presented to a limit amplifier and compares the same with a clutter threshold reference potential. A low-pass filter in the feedback loop then smooths or averages the clutter deviation from the reference potential to adjust the clutter level out of a log IF amplifier so that the nominal clutter signal level of close-in returns does not exceed a predetermined magnitude. A second embodiment includes a dual time constant filter in the feedback loop. A comparator circuit senses the leading edge of clutter return signals and switches the feedback loop to its faster time constant mode allowing dynamic compression of smaller time constant pulses.

Abstract: A single channel, or push-to-talk transceiver includes a switch-controlled Gunn oscillator for generating the carrier frequency during transmission and a continuously operating local oscillator for demodulation of a received signal in the receive mode. When the push-to-talk switch is depressed, the transmit oscillator is energized and leakage signals cross the circulator to the receiver portion of the transceiver. An RF AFC loop between the transmitter and receiver portions includes a low-pass filter at the preamplifier output which serves as a simple slope discriminator. This output is detected and used to close an electronic servo loop. Once closed, this servo loop locks the transmit oscillator frequency relative to the local oscillator thereby preventing frequency drift during warm-up.

Abstract: A voltage variable oscillator feeds an FM modulated signal to be transmitted to an orthomode transducer connected to a dual polarization antenna, another port of the orthomode transducer feeding received FM signals to a single ended mixer, the output of which is passed through an FM receiver. The orthomode transducer leaks a portion of the transmitted wave to the single ended mixer, for use in lieu of a local oscillator, thereby limiting the requirements to a single microwave oscillator. The output of the FM receiver is applied to a cancellation circuit where the transmitter modulation is cancelled from the FM receiver output in response to delayed transmitter input signals.

Abstract: A transceiver, adapted for use as either a master or a slave in a duplex pair, has a single, voltage-tunable, solid-state oscillator to provide the carrier frequency wave, a small portion of which is mixed with the received wave and applied therewith to a single ended mixer; an automatic gain-controlled loop cancels transmitter input modulation from the receiver output. The desired oscillator carrier frequency of the master transceiver is locked to a frequency within the pass band of an RF filter at the receiver input and separated from the center frequency of the filter by one-half the receiver IF frequency. The slave transceiver is first locked to a frequency within the pass band of the filter on the opposite side of its center frequency and separated therefrom by one-half the IF frequency (the slave thus offset from the master by their common IF frequency).
