Abstract: 229,314. Smulders, C. A. Feb. 13, 1924, [Convention date]. Pianoforte actions.-In a horizontal action the jack 7 pivoted at 8 to an arm 5 has a widened top and is directly acted on by the key 2. On depression of the key, the point of contact of the jack with the hammer-shank moves from A to B towards the hammer pivot, thus increasing the action on the hammer. The arm 5 then contacts with a stop 6, and the jack-head moves to the left and somewhat downwards owing to the continued action of the key on the jack-heel c. After the rebound the hammer rests on the pick, which allows rapid repetition. On release of the key the jack is returned into contact with a stop 9 by a spring 11 and wire 12. The application of the action to upright, pianofortes is also described.

Title: Improvements in semiconductor devices
Inventor: SMITH JAMES GILBERT
IPC: H01L29/72
Filed: 1965-01-29
Abstract: 1,103,771. Semi-conductor devices. ASSOCIATED SEMICONDUCTOR MANUFACTURERS Ltd. 29 Jan., 1965, No. 4027/65. Heading H1K. In a semi-conductor device which is not completely circularly symmetrical the effect of " current hogging " is reduced by contacting one region with a conductive layer the distance of the edge of which from the junction decreases as the distance from a low resistance contact applied to the layer increases. " Current hogging " is the concentration of the current flow at certain areas of a junction due to the geometry of the device. In a first embodiment a planar transistor having interdigitated base and emitter regions is produced and, as shown in Fig. 4, the emitterbase junction 13 is protected by an oxide layer the edge 12 of which defines the effective edge of a conductive layer 15 forming the emitter contact. Layer 15 is provided with a low resistance contact 18 and the effective edge 12 of the emitter contact 15 is closest to the junction 13 at those regions furthest from contact 18. Since the base contact carries much less current than the emitter contact the effective edge 11 of the base contact 14 can be spaced a constant distance from the junction 13. In a modification, Fig. 5 (not shown), the effective edges of the base and emitter contacts are spaced a constant distance apart, but the location of the PN junction between them varies to reduce the effect of " current hogging " in the base and emitter regions. In a further embodiment, Fig. 6 (not shown), the base and emitter regions are circularly symmetrical, the emitter electrode is in the form of a circular contact layer and a low resistance contact to the layer both symmetrically arranged, but the base contact is applied to a base contact layer at a peripherally located point, and to reduce the effects of " current hogging " the distance of the effective edge of the base contact layer from the junction is varied by forming the outer edge of the oxide covering the junction in a circle the centre of which is displaced from the centre of the emitter region towards the base contact. The method of producing a planar epitaxial NPN transistor is described in detail. The contact layers comprise aluminium evaporated over the masked surface and masked and etched to produce the required electrodes. The device is gold-soldered to a molybdenum disc which is soldered to a copper header. The contact layers are connected to lead-out wires by means of aluminium wires. It is also described how the method can be modified to produce mesa transistors. Reference has been directed by the Comptroller to Specification 1,032,599.

As shown in Fig. 1, an oscillatory circuit F1 of fixed frequency, and an auxiliary circuit F2 including an inductance l1 varied by an adjustable contact B, are jointly coupled to a detector D and sound-reproducing instrument E, which emits a beat note determined by the difference in the frequency of the circuits F1, F2. The inductance l1 mav be wound on a former over which is stretched a wire B, Fig. 2, a comb-like member 5, Fig. 8, or a zig-zag wire woven into a fabric strip (Fig. 9, not shown). Pressure applied to the contact member includes a selected number of turns of the coil l1 in series with the other coil L1 and the condenser C1. Note indicators or a keyboard may be associated with the wire B. The coil is preferably wound on a tapering former so as to enable each tone or octave to occupy the same length along the contact member B. The variable resistance, Fig. 6, for controlling volume comprises a U-tube 1 containing mercury, and a pair of electrodes 1, 2 of which 2 is immersed in a column of resistance liquid variable by pressure applied to a bulb 4. In another form (Fig. 7, not shown), a fixed wire-wound resistance is variably immersed in mercury, the height of which is controlled by an air-pressure bulb. The bulb may be controlled by the foot or it may be placed beneath the coil former so as to be actuated by the pressure on the contact member B or the keyboard.
