Abstract: A method of making a thin lens having a desired high order curvature includes the steps of providing a layer of transparent photoresist; generating a continuous tone exposure pattern for exposing the photoresist such that when exposed and developed the layer of photoresist will possess the desired high order curvature; exposing the layer of photoresist; and developing the layer to produce the thin lens.

Abstract: A gun is provided having an operating mechanism which receives and stores energy from the gun housing during the recoil of the gun and which subsequently utilizes the stored energy in two distinct phases during the counter-recoil of the gun.

Abstract: A silicon monolithic integrated circuit comprising a DC biasing network and three sets of full wave, synchronous, gated, transistor demodulators to demodulate the red, blue and green color different signals which are present in a composite television signal. The DC biasing network includes; a voltage regulator for providing a direct current voltage independent of variations in the magnitude of a power supply voltage the variations may be caused by voltage transients or varients in the temperature of the monolithic chip, and a direct current bias amplifier connected to the voltage regulator for providing a zero differential temperature coefficient direct current bias voltage to the outputs of the three sets of demodulators. Also disclosed is a blanking amplifier to facilitate direct current restoring at each of the outputs of the demodulators, the blanking amplifier being responsive to a blanking input signal.
