In electrical apparatus, having a variable resonant circuit 12a or 12b tunable over a given frequency band, a frequency-dependent coupling means 13<SP>11</SP> or 13<SP>1</SP> is connected to couple the input signal 10a or 10b and output load 11<SP>11</SP> to the resonant circuit so as to vary the coupling to the input signal and load inversely with respect to each other and as the resonant circuit is tuned over the range, to maintain the loading on the resonant circuit substantially constant such that the tunable bandwidth of the apparatus is maintained substantially constant. As shown the coupling means 1311 and 13<SP>1</SP> include capacitive and inductive components which vary inversely with respect to each other as the V.H.F. and U.H.F. tank circuits 12a, 12b are tuned over their ranges to maintain the loading and bandwidth substantially constant. The outputs from these circuits are connected to a transistor R.F. amplifier 11<SP>11</SP> of a television receiver which can feed a mixer. The two tank circuits 12a, 12b are mechanically coupled so that when one tuning element V.H.F. or U.H.F. is engaged the other element U.H.F. or V.H.F. is disengaged. The impedances of the capacitor 19 and inductor 22, capacitor 23 isolate the U.H.F. and V.H.F. circuits from one another when one is selected.

Title: Circuits with field effect transistors
IPC: H01L27/06
Filed: 1964-10-26
Abstract: 1,041,318. Integrated semi-conductor circuits. WESTINGHOUSE ELECTRIC CORPORATION. Oct. 26, 1964 [Nov. 21, 1963], No. 43575/64. Heading H1K. [Also in Division H3] A single semi-conductor body contains a field effect transistor and a PN junction diode connected to the gate electrode of the transistor in such manner that when a current passes in series across the diode junction of the transistor the former junction is forwardly biased when the latter junction is reversely biased. The device is designed for use in circuits (see Division H3) in which the diode serves as a high impedance through which to apply a bias potential to the transistor gate: at the low currents (of the order 10<SP>-9</SP> amp) drawn by the gate the forwardly biased junction diode behaves as a resistor with a resistance of the order of megohms. The device shown comprises the diode D1 and the field effect transistor FET1, together with a PN-junction capacitor C1 and a bipolar transistor BT1 all forming part of an audio amplifier circuit (Fig. 5, not shown). It is formed by epitaxial growth from the vapour phase of phosphorus-doped silicon on to a P-type silicon substrate 42 to form N+ and N layers 49 and 40 which are then isolated into separate regions by deposition, through an oxide mask, and subsequent in-diffusion of boron to form the P-type walls 43. Further masked diffusion of boron and phosphorus produce the zones 45 and 47 in each separate N zone 40. The diode D1 is between electrodes to zones 47 and 45 with zone 40 shorted to zone 45; the field effect transistor FET1 has source and drain electrodes to zone 45 and a gate electrode to zone 47; the capacitor C1 and transistor BT1 are similarly formed by electrode connections to appropriate zones. The interconnections such as 62, 63, 66 are shown as external leads but are in fact conductive tracks laid down on a protective oxide layer (not shown). In particular, the connection 63 between diode D1 and the gate of FET1 is such that the two junctions in the series circuit between terminals 64 and 65 are oppositely biased.

Abstract: 1379840 Punching BRUDERER AG 26 Sept 1972 [1 Oct 1971]. 44442/72 Heading B3W The stroke of a punch press driven, through connecting rods 7, by a shaft 3 having inner and outer eccentrics 4, 6 is adjusted by holding the outer eccentric 6 and rotating the inner eccentric 4, a resilient member 37 being stressed by axial movement of a sleeve 30 to form a friction coupling in the adjustment drive. A toothed plunger 9 coupling the eccentrics 4, 6 is retracted, against a spring 12, by an eccentric pin 15 on a shaft 16 which is rotated by an extension member 21 within limits set by a stop 18 engaging an arcuate groove in the shaft. With the outer eccentric 6 held by a stop 39 operated by a crank-pin 41, the sleeve 30 is moved along the member 21 by turning a nut 29 which engages an inner sleeve 26 bearing on the sleeve 30. This movement of the sleeve 30 stresses a slotted cup spring 37 so as to couple a bevel-gear 31 to a flange 36 which is connected to the inner eccentric 4 by bolts 19. Rotation of a meshing bevel-gear 33 thus turns the inner eccentric in the stationary outer eccentric 6. The inner sleeve 26 is keyed to an extension of the flange 36 and bears graduations 43 opposite marks 44 on a flange of the outer sleeve and a mark 45 on the casing.
