Filed: 1972-08-31
Abstract: 1440918 Lamp failure alarms CAV Ltd 14 Aug 1973 [31 Aug 1972] 40360/72 Heading G4N A lamp failure alarm comprises a series combination of a resistor 41 and contacts 42 operable e.g. periodically, to cause flashing of the monitored lamps 39, a capacitor 51 charged by a voltage sensing device 46-50 when the voltage across resistor 41 falls below a predetermined value, e.g. due to failure of a lamp 39, the capacitor voltage inhibiting illumination of a warning lamp 62 via a transistor switch 53-61 when the contacts 42 are opened. Operation is initiated by the closing of a switch 40 and transistors 53, 61 are rendered conducting to activate lamp 62 when contacts 42 which are connected across the circuit of the lamp, open. However, if one of the lamps 39 fails, then a transistor 46 conducts when the switch is closed to charge a capacitor 51 so that transistors 53, 61 remain biased off and the warning lamp 62 remains extinguished when contacts 42 open. A capacitor 64 inhibits false operation by transients. Fig. 1 (not shown) illustrates an alternative circuit using a slightly different transistor switch and control circuit.

Filed: 1971-09-09
Abstract: 1321328 Semi-conductor devices RCA CORPORATION 9 Sept 1971 [18 Sept 1970] 42173/71 Heading H1K A CMOS integrated circuit comprises a complementary pair inverter having a 1st-P type IGFET in series with 2nd N-type IGFET between supply and ground; the insulated gate electrodes receiving an input signal and the drains receiving input over a series resistor shunted from both ends to supply over anodecathode circuits of diodes, while the common gates are shunted to ground over cathode anode circuit of a further diode, (Fig. 1). Parasitic positive pulses appearing on the supply, ground, input or output terminals are discharged through the diodes to protect the gate electrode insulation from breakdown. In construction (Fig. 2) a semi-conductor body 34 of, e.g., Si of N-type conductivity has spaced P + source and drain regions 38, 39 thermally diffused, e.g., by Bo from a nitride source over a mask to form a steep concentration gradient and an abrupt PN junction. A P-type well 40 diffused to greater depth with a more gradual concentration gradient is similarly formed, and the Bo impurity is thermally redistributed by heating in dry O. The surface concentration is outdiffused by heating in H 2 O vapour, resulting in a low impurity concentration and a gradual PN junction. N+ type source and drain regions 42, 43 are formed in well 40 by diffusion of P. The gate electrodes 20, 22 overly the channels between the respective source and drain regions with thin oxidized insulators 44, 45, and diffused P + and N + guard rings encircling transistors 12, 14 and P+ or N+ regions (not shown) operating as resistors or tunnels. Diffused P-type regions 50 of depth and concentration gradient such as to provide a gradual PN junction 52 with body 34 functions as the series resistor and a boundary of region 50 intersects the surface of the body and is overlapped by P + regions 54, 55 of steep impurity gradient, electrically coupled to the resistor as anodes for the associated diodes which define abrupt low breakdown PN junctions with the body as a common cathode coupled to the supply. Metallic conductors 60, 61 are applied to these regions, and N+ region 62 within P-type well 40 serves as cathode of the remaining diode, which is connected over lead 65 to metallic contact 61. In a modification, a pair of N+ type regions overlap the boundary of the diffused P-type resistor region and are formed by thermal diffusion of P from the oxychloride to reduce the breakdown voltage of the associated diodes. The spacing of the regions controls the effective resistance, and the forward diode characteristics are sharp. Regions 54, 55 may be omitted, with other ohmic contact to the resistance region.

In the released condition of the brake (Fig. 1) the clamping member 29 is tiltably pressed by a spring biased collar 27 against a cover-plate 24 and the clamping member 29 is frictionally engaged with the rod 18 and as the brake is applied the clamping member 29 moved to the right with the rod 18 through a distance "X" equivalent to the allowed release clearance of the friction carrier 12. If this clearance is exceeded due to wear of the friction lining, (Fig. 2) a projection 53 will engage a shoulder 55 of a cylindrical housing 17 which shoulder 55 will release the frictional engagement of cam 41 with rod 18 and allow the rod 18 to the move forward to maintain brake engagement. On release of the brake the rod 18 is retracted only a distance X and hence the rod 18 is adjusted for taking up wear. An identical retractor assembly 10 may be provided on the other side of the disc 13 and a plurality of assemblies 10 may be provided arcuately in a torque frame 11. The mechanism of the invention is stated to have utility in clutches.
