Abstract: A high speed two micron CMOS comparator uses an input differential stage (11) having feedback current mirror loads (18, 20) providing high speed current signals to an output cascode stage (28). Current mirror arrangement provide fast signal propagation through the comparator. Hysteresis is established by the output of the comparator positively fedback through a similar feedback differential stage (42) superimposing controlled current signals into the cascode stage. Hysteresis of the output signal respecting a differential input signal is controlled by the ratio of bias currents of internal current sources which ratio is relatively insensitive to temperature changes.
Patent JP-H028291-B2 (JP)
IPC: G02F1/137
Filed: 1981-03-17
Abstract: In a matrix display device having a cholesteric liquid crystal the bistability effect is used which some cholesteric liquid crystals show. The liquid crystal shows a frequency-dependent relaxation of a positive to a negative dielectric anisotropy. After writing the information the light-scattering picture elements have a focal-conical texture and the transparent elements have a homeotropic-nematic texture. The information can be stored for a longer period of time by causing the homeotropic-nematic texture of the transparent elements to change into the substantially transparent planar-conical texture. This is produced rapidly by applying across all picture elements a voltage of a frequency at which the liquid crystal has a negative dielectric anisotropy. The focal-conical texture of the light-scattering elements is substantially not disturbed by this voltage. During the presence of this voltage the written information is continuously visible.

Abstract: For a more effective elimination of gaseous, aerosol-like and/or dusty contaminants and pollutants from the waste gases of refuse incinerators, a process is proposed in which the temperature of the water-containing residual scrubbing gas which, if appropriate, has already been treated according to the wet process, dry process or semi-dry process, is reduced to such an extent that at least the main part of the water vapour still contained in the gas condenses out in the heat exchanger (13), pollutant contents also being precipitated with the water vapour or themselves being caused to condense, to be absorbed, to be adsorbed or to be bound in another way. The precipitated condensate is aftertreated chemically-physically in a suitable manner. The process is also distinguished by a favourable energy balance, since less water evaporates and has to be discharged via the stacks. In addition, apparatus particularly suitable for carrying out the process is proposed (see Figures 2-4, 6 and 8). Figure 6 shows a design of the apparatus, by means of which the process can be monitored and controlled via pollutant concentration measurements. <IMAGE>
