Title: Fet circuit

Filed: 1973-12-05
Abstract: 1434640 FET driver circuits INTERNATIONAL BUSINESS MACHINES CORP 5 Dec 1973 [27 Dec 1972] 56259/73 Heading H3T An FET driver circuit comprises an inverter stage T1 and an output stage including an FET T5 and a boot-strapping capacitor C1 for overcoming the threshold voltage drop of T5, coupled between a pair of input and output nodes, a delay circuit 30 and an inverting FET T13 also coupled between the same nodes, the delay circuit 30 including an input circuit T6, T7, an inverter T8, T16, T17, C3, FETs T10, T11 having their source-drain paths connected in series for discharging the output node G of the delay circuit, an arrangement T9, T12 responsive to the inverter for charging the node G as well as a common connection F between FETs T10, T11. In operation, when the input is at an up level, T1, T3, T7 and T19 conduct holding nodes A, B, D and the output node at a down level. A down level input signal turns off T1, T3, T7, T19 and the node C charges up via T4 but the output node remains at the down level until T13 is turned off by the input delayed at 30. In the delay circuit 30, nodes F, G are charged via T9, T12 when node D is at the down level and nodes G, F are discharged via T11, T10 when node D is at the up level. The delay in the delay circuit is constituted by a resistance factor introduced by T6 and a capacitance factor introduced by T10, T11. FETs T40 ensure that nodes F, G remain in the up level when the input is at an up level and FET T42 ensures that node D remains in the up level when the input is at a down level. The delay in turning off T13 enables node C to be charged to almost twice the supply potential so that T5 is driven hard as to charge the output node to supply potential. In the alternative embodiment of Fig. 3 (not shown), T3, T19 are not present and an FET (T18) is connected between nodes B and D as to make the duration of the output signal on the output node the same as the duration of the input signal.

Title: Toy telephone
IPC: A63H33/30
Filed: 1969-11-20
Abstract: 1,263,595. Toy telephone. M. I. GLASS, [trading as MARVIN GLASS & ASSOCIATES]. 20 Nov., 1969 [19 Dec., 1968], No. 56799/69. Heading G5R. In a toy telephone, the telephone rings when switched on and when its receiver is lifted plays back from an internal gramophone, incorporating a record having a plurality of messages recorded thereon, a message which can be previously selected by actuation of the telephone dial. On pushing switch member 24 inwards a heating coil 192 on a bi-metal element 180 is energized and after a delay the element moves a snap-action switch member 186 into contact with a fixed member 182 and energizes turntable drive motor 22. With the telephone unit 16 on its rest the turntable 26 is in its lower position where a gear 120 secured thereto meshes and drives a gear train, Fig. 4 (not shown), which operates the telephone bell. When the telephone receiver is lifted a first spring-loaded lever 206 is moved upwardly carrying with it a second lever 212 which raises the turntable 26 to a position in which needle 60 of tone-arm 58 can engage record 28 to play the next or a previously selected message. At the same time the turntable gear 120 moves out of mesh with the telephone bell gear train. The sound picked up is amplified in a diaphragm assembly 56 and passed via a tube 74 to the telephone receiver. When the receiver is returned to its rest, a member 220 on lever 206 moves the snap-action switch member 186 to its off position, the heating coil is re-energized and after a delay the member is again moved into contact with the fixed member 182 and the process is repeated to play the next recorded message. The telephone dial 14 has fixed for rotation therewith a gear member 90 which engages a spring-loaded gear 84 integral with a cam member 86. On operating the dial a rib 93 on the cam member lifts a pivoted plate 113 and this raises tone arm 58 so that the needle 60 is freed from the record and an abutment 110 on the cam member swings a two-armed lever 98 about its pivot to move the pick-up arm 58 to its innermost position. Continued movement of the dial moves the abutment out of engagement with the lever 98 and this returns under the action of spring 100 to its initial position. The pick-up arm is now acted upon by the cam surfaces A, B, C &c., so that the arm is moved to a selected position and when the dial is released and returns to its initial position the arm is lowered on to the selected position of the record. By operating a lever 46 the centre spindle of the turntable can be lowered so that records can be changed via slot 48.

The substrate is locally softened and pressure applied to the member to complete the insertion, one end of the member projecting through the opposite side of the substrate. The process may be applied to fixing shafts &c. to the chassis of a tape recorder. Apparatus for performing the method comprises a jig 25, Figs. 4 and 5 (not shown), having posts (59) for locating the chassis 65 and hollow posts 60 for guiding the shafts 71, Fig. 7B, as they are inserted in holes in the chassis. Rollers 58 on the jig run in tracks 29 in a base 22 as the jig is moved against a stop 52 and microswitch 51 for detecting that the jig is correctly positioned beneath plungers 40 which preferably are also arranged to heat the shafts 17 and thus locally soften the chassis. The switch 51 also starts the setting operation which is controlled by a timer. The shafts are initially inserted in the holes which pass the shanks of the shafts but not their enlarged knurled heads. Each presser 40 and its resistance heater 39 is carried in a tube 53 mounted in a slide 36 which is operated by a pneumatic or hydraulic cylinder 33.
