Abstract: 1,024,674. Transistor switching circuits. RADIO CORPORATION OF AMERICA. Feb. 4, 1964, [Feb. 14, 1963] No. 4755/64. Heading H3T. [Also in Division H1] In a circuit including an insulated-gate field-effect transistor, e.g. 11, formed on a semi-conductor substrate, the substrate 8 is biased with respect to the source 15 to reduce the source-to-drain current to substantially zero in the absence of an input signal on the gate 16. The circuit described is an integrated assembly of eight NAND circuits 9, 30, 31, 32, 33, 34, 35, 36, one input to each being connected to a common input terminal 21. Each NAND comprises a pair of insulated-gate fieldeffect transistors, e.g. 10, 11, with their sourcedrain circuitry in series. When both gates 13, 16 are positive (logical 1) current flows through the source-drain circuit to make the drain 17 earth potential (logical 0) no current flows with other input conditions and the drain 17 is at the potential of terminal 19 (logical 1). The substrate s is common to all transistors, and is biased by means of potential divider 37, 38.
Patent SE-368737-B (SE)
Inventor: BODEN K
IPC: F16C39/00
Filed: 1970-04-13
Abstract: A mechanical contact-free bearing system for a rotor, e.g., in a vacuum pump operating on the Holweck principle, rotatable at high speed comprises a magnetic system which includes at least one carrier magnet for suspending the rotor with its axis vertical. The bearing system includes at least one stabilizing device for counteracting and damping gyratory movements, e.g., procession and nutation, of the rotor. The stabilizing device includes sensors for producing signals responsively to deviation of the axis of the rotor from a predetermined position. An electronic control device amplifies the sensor signals and advances them in phase to produce output signals. Electromagnetic means utilize such output signals to apply electromagnetic forces to the rotor to apply correcting lateral forces to the rotor and further forces to anticipate the gyratory effect of such correcting forces and to damp oscillations of the rotor.
