Abstract: 1454085 Luminescent materials and uses thereof MINNESOTA MINING & MFG CO 11 Oct 1973 [12 Oct 1972 10 Sept 1973] 47612/73 Heading C4S [Also in Division H1] An L.E.D. comprises a single crystal of ZnO which exhibits a fluorescent efficiency of not less than 0.001 in a band between 3700Š and 4000Š at 77‹ K., and includes a substantially ohmic cathode 36 and a rectifying anode 34, the diode emitting violet light at room temperature. The cathode may be of low work function In, or Zn or tin oxide and/or indium oxide and preferably of work function # the work function of ZnO. The anode may be high work Cu, Ag, Au, Pt or C and ultra-violet responsive phosphor 30 may convert the L.E.D. emission. Jig 38 facilitates contact formation. Fig. 4 (not shown) is a coherent radiation source with reflector layers (60), (62), and Au anode (64). Mechanisms are discussed including decay of free excitons, and donors are provided to compensate acceptor concentration of <10 p.p.m. by heating in the presence of ZnS for example for Zn diffusion, followed by quenching. Crystals may be thin slabs from a single crystal or naturally grown and selected by laser or Hg arc excitation according to efficiency. Operation may be A.C. or D.C., the resistivity may be 1 # cm. for 10<SP>17</SP> electrons/c.c. and reduction of acceptor states provided by Li and Na and in amount <10<SP>16</SP>/c.c. is disclosed. Crystal orientation is discussed and surfaces preferably shaped to minimize internal reflection and to focus. Green fluorescence of as grown ZnO may be countered by excess Zn doping and removal of an outer layer. Detailed examples specify voltages and current densities, band gaps, dimensions and further electrode details, including as examples only, a plurality of point contacts provided by Au particles in silicate binder, Au needles with blue ZnS phosphor on the opposite crystal face, four anode dots, gold paste over a blue organic phosphor on the oxygen face, the same phosphor on the opposite face increasing brightness, Au coated silica, rough 10Á Au spheres, and cleaved or otherwise mechanically deformed evaporated films.

Granted: 1990-09-29
Abstract: The circuit comprises a first threshold comparator (A) with hysteresis arranged to provide a reference signal (V1) indicative of the zero-crossing of the sensor signal (Vp ). Also connected to the sensor (1,W,P) is an integrator circuit (B) whose output is connected to the input of a second threshold comparator (C). The latter provides an enabling output (V 2) signal only when the integrated signal (V i) remains above a reference signal (S2). A logic circuit (D) is connected to the two threshold comparators (A,C) and transmits the output reference signal (V1) provided by the first comparator (A) only when the second comparator (C) outputs the enabling signal (V 2). Immediately after the first comparator (A) has transmitted this reference signal (V1 ) to the logic circuit (D), the logic circuit (D) is disabled. This can conveniently be achieved by the stopping of the operation of the integrator (B). The time window during which the logic circuit (D) is enabled is thus reduced and the danger that the logic circuit (D) may transmit spurious output signals generated as a result of interference picked up is consequently reduced.

Energy is stored during quiescent periods and released at the onset of the control pulse with the min. possible time constant. Alternatively this capacitor may be connected between the end of the collector choke (Lc) and the emitter or base, or between the current source (Vcc) and the emitter or base.

In a fluid-pressure braking system, e.g. a compressed-air system for road vehicles, having both service and emergency spring actuators 22, 11, respectively, the former being supplied by a reservoir 6 via a conduit 18 under control of a driver's valve 15, and the latter having a chamber 10 for compressing the spring 13 which is supplied by a reservoir 5 under control of a manually operated valve 7, the exhaust of the valve 7, which releases fluid from the chamber 10 to apply the spring brake, is connected via a non-return valve 8 to the conduit 18, so that the released fluid can exhaust only via the exhaust 16 of the driver's valve, the valve 8 being resiliently loaded in the forward direction to further retard release from the chamber 10. This ensures that, whatever pressure exists in the chamber 19 of the service actuator 22 at the time the valve 7 is operated to effect an emergency spring application of the brake, the total brake-applying force will not exceed the maximum force due to a service application alone.
