Title: Surface-controlled field effect semiconductor device
IPC: H01L29/76
Filed: 1971-08-09
Abstract: 1332255 Transistor binary stores INTERNATIONAL BUSINESS MACHINES CORP 9 Aug 1971 [12 Sept 1970] 37264/71 Addition to 1317493 Heading H3T [Also in Division H1] In a surface controlled semi-conductor FET of the kind described in Specification 1,317,493 wherein an electrical connection is provided between the gate and the channel zone to enable a gate pulse to drive the channel conductive so that the conductivity is maintained after pulse cessation by transfer of potential tapped from the channel to the gate, the contact point 9 of the connection provides a blocking diode path at Schottky barrier 11 which is reverse biased with respect to diode 10 formed by the PN junction between the substrate and region 3, and the substrate is e.g. p-type Si with a Schottky barrier formed by e.g. Pt (or Au) gate metal in contact therewith to generate e.g. Pt, Si at the contact point (Fig. 2). In a modification (Figs. 3 and 4, not shown) an additional N<SP>+</SP> region is formed below the gate channel contact point to constitute an oppositely poled Schottky diode path oppositely biased to the Schottky diode formed at contact 9 of the gate electrode. This is blocked when drain voltage exceeds gate voltage, and forward biased on positive gate pulse solely as gate voltage exceeds drain voltage, while the junction of the N<SP>+</SP> region is blocked. At stability with channel current flowing the gate voltage is slightly less than the N<SP>+</SP> region voltage. In a storage cell (Fig. 5) two gate-channel connections 8, 13 are provided at the drain and source ends of the channel with a Schottky diode barrier in series with contact point 9, the connection 8 transferring channel potential from drain to gate to obtain a latch-in without gate to drain current flow, while connection 13 prevents the gate from charging in the second stable storage state of zero channel current. Connection 8 is replaceable by a reverse diode path and a N<SP>+</SP> region provided under Schottky contact point 9. The storage cell is addressed by a FET 15 connected to the gate electrode G for linkage with word and bit lines WL, BL. In a modification (Figs. 6, 7a, 7b) two gate channel connections 8, 13 are provided; the former being associated with N<SP>+</SP> region 12 and the contact points 9, 16 constituting Schottky diodes 11, 17. Region 12 and contact point 16 are located adjacent the drain zone 3, and the N<SP>+</SP> region 12 is connected to a potential higher than contact point 16, which is located at approximately zero potential so that its diode 17 is forward or reverse biased according to the storage state of the device. At "O" state gate 5 at zero potential so that diode 17 is forward biased holding gate potential at zero, but on application of a pulse to gate 5 for "I" state, the gate is momentarily driven positive and diode 17 is reverse biased to prevent gate electrode 5 from discharging, so as to maintain the "I" state.

IPC: F28D19/04
Filed: 1962-10-12
Abstract: 1,025,952. Thermal regenerators. SVENSKE ROTOR MASKINER A.B. Oct. 12, 1962, No. 38712/62. Heading F4K. A thermal regenerator comprises a rotor shell 10 joined to a central rotor post 12 (Fig. 1, not shown) by radial partitions 11 to form sectorshaped compartments filled with heat-transfer material; a stationary housing 20 surrounding and spaced from the rotor shell and having end plates 21; an axially movable cantilever beam 24 carrying sealing means 22; and means operated by the rotational movement of the rotor for intermittently applying an axial force to the beam 24 to maintain independent movement of the beam relative to its adjacent radial partition 11, which movement might otherwise be prevented, for example, by thermal distortion of the partition 11 or by slag &c. deposits becoming wedged between the beam and the partition. As shown, a push-rod 36 extends radially through the rotor shell 10 near the outer end of a partition 11. The push-rod is held in position by a housing 40 and by a compression spring 46 which urges the push-rod radially outwardly. Attached to rotor housing 20 is a housing 54 containing a pivoted thrust pad 52 radially adjustable by a screw 56. As the rotor rotates, the thrust pad 52 engages the end of the pushrod (see also Fig. 3, not shown) and forces it against one arm 49 of a pivoted bell-crank causing the other arm 47 of the crank to engage a buffer plate 48 mounted on the beam 24 and hence applying an axial force to the beam. As the push-rod moves past and out of engagement with the thrust pad, spring 46 expands suddenly and throws the push-rod outwards until a collar 44 thereon strikes end 42 of housing 40 and effects on the rotor shell and radial partition a rapping action that tends to maintain the required independence of movement the radial partition and its adjacent cantilever beam. By varying the spacing of the thrust pads 52 any desired intensity of rapping can be achieved. A circumferential seal 28 is also fitted to rotor shell 10 to engage sealing ring 32 attached to end plate 21.
