Abstract: An improved one shot multivibrator circuit is described which is particularly adapted for use with field-effect transistor (FET) manufacturing techniques such as metal oxide semiconductor (MOS) large scale integration (LSI) manufacturing techniques. Such a one shot multivibrator circuit is particularly adapted for FET application because the period of its output pulse is independent of the threshold voltages of the transistors used in the circuit design. The one shot multivibrator circuit comprises a capacitor for fixing the period of the output pulse; a bias network including a current mirror as a constant current source for charging the capacitor; a first inverter stage comprising a switching transistor and a load transistor for controlling the charging and discharging of the capacitor; and a second inverter stage as the output stage for providing the output pulse having its turn-on controlled by the first inverter stage and its turn-off controlled by the voltage level on the capacitor.

Abstract: A high speed field-effect transistor (FET) bistable multivibrator circuit is described. This bistable circuit employs two stable states and comprises a first section and a second section. Each section comprises a load transistor of high resistance magnitude for insuring a high gain; input means for storing a voltage representation of the input signal applied to that section; switching means responsive to the voltage stored in the input means for turning on one of the switching transistors; and cross-coupling and driving means, responsive to the switching transistor which turns on, for discharging the voltage representation of the input signal applied to the switching transistor in the opposite section.

Abstract: A liquid crystal display device having a series of transparent panels, the inner surface of each panel successively supporting a transparent electrode film and an alignment film which sympathetically aligns crystals of liquid crystal material into the direction of film growth. The alignment films have their directions of alignment alternately pointing in the horizontal or vertical direction. Liquid crystal material is placed between adjacent alignment films to form a series of liquid crystal display cells. A character may be formed by certain transparent electrodes in the device. To read out a selected character from the device, the liquid crystal display device is placed between a light polarizer and a light analyzer. With an even number of cells in the device, the polarizer and analyzer are crossed to produce a dark background. The crystals of the unenergized cells, having crossed alignment films in them, will rotate polarized light which is passing through them by 90.degree..
