Title: Organic thin film transistors
Inventor: KUGLER THOMAS
IPC: H01L51/00
Filed: 2009-04-16
Abstract: A method of forming an organic thin film transistor includes a process for aligning the organic semiconductor molecules to improve charge mobility in the channel region. A surface outside the channel region is seeded with one or more crystallisation sites 14, 16 prior to deposition of a solution of the organic semiconductor 8 onto the seeded surface and over the channel region. The crystallisation sites may comprise boundaries between surface patterns with differing wetting properties, or physical structures. The organic semiconductor forms a crystal domain at the crystallisation sites (fig 4; 8), the crystal domain growing from its crystallisation site across the channel region in a direction determined by an advancing surface evaporation front. The direction and rate of movement of the surface evaporation front is controlled for example by dragging a shearing substrate in contact with the orgainic semiconductor thereby controlling the direction and rate of growth of each crystal domain across the channel region from the crystallisation sites.

Filed: 1938-04-01
Abstract: 577,780. Aero-engine mountings. COWDREY, C. L., BARRINGTON, T. B., and ELLIOTT, A. G. April 1, 1938, No. 10069. [Class 4] In an aircraft the engine-mounting is connected to the fuselage or nacelle structure by intermediate members which carry a bulkhead or the like, each member being readily detachable from the fuselage and having the engine-mounting independently and readily detachable from it. Thus, the engine may be replaced by one of the same or of a different type, and the fuselage may be standardised, while the bulkhead, on which auxiliary mechanisms such as hydraulic and vacuum pumps, &c. may be replaced by one carrying auxiliary mechanisms suited to the different-type engine. As shown, the enginemounting which includes members 25, 36 is connected by intermediate members 38 to the corners of a rectangular frame 8, 9 secured to the members 5, 10, 35 forming part of the fuselage. A part 13 of the intermediate member 38, Fig. 2, extends between a plate 12 and the machined face 11 of a forging 6 and is formed with an internal spherical seating 14 supporting a split spherical bush 15 which has a central tapered hole receiving a split tapered collet 16 fitting a set-screw 17 adapted to -secure the parts together. The spherical bush 15 is expanded in its seating by the collet so as to lock the intermediate member in any desired angular position to suit different engine-mountings. A bolt 27 is screwed into the end of the member 25 of the engine-mounting and is formed with a chamfered shoulder 26 adapted to fit in a tapered socket 28 on the other part 24 of the intermediate member 38, a flanged coupling nut 29 securing the bolt thereto. Alternatively, the nut may be screwed on the member 25 and the shoulder formed on the member 38. The bulkhead 31, which is secured to a flange 30 on the member 38, carries a peripheral T-flange 33 to which the cowling is secured. The forging 6 is bolted at 37 to the fuselage member 5 and formed for connection to the other fuselage members 7, 8, 9, 10. In another construction, the spherical bush 15 and collet 16 are dispensed with and the intermediate member is mounted directly on the shank of the screw 17 so as to be adjustable only about the axis of the screw, different intermediate members being provided for different angular . settings of the member 25. In each construction removal of the screws 17 enables the engine complete with its mounting and bulkhead 31 to be removed and replaced by another unit which may comprise a different engine and bulkhead but a similar mounting. Alternatively to replace the engine by one of the same type the nuts 29 are released, the bulkhead remaining in position.

An electrical installation wherein a load such as an electric furnace is supplied over a conductor 3 is provided with capacitors which, among other things, improve the power factor of the installation, the capacitors being connected to the line 3 by way of a series connected transformer, the arrangement being such that, to suppress oscillations, the series connected transformer is divided into two parts 2a, 2b and the capacitor is in the form of a group of capacitors 1a, 1b, each capacitor 1a, 1b being connected to a separate secondary winding of the transformers 2a, 2b so that the capacitors receive equal voltages of reverse polarity and the magnetic core of the transformer part 2b being so over-dimensioned that, in operation, it never saturates. Thus during normal operation the resultant voltage across the capacitors 1a, 1b is zero but when an overload or a surge occurs in the line 3 the core of the transformer part 2a saturates causing the voltage which is applied to the capacitor 1a alters in phase by 180 degrees. The resultant voltage across the capacitors 1a, 1b now produces a current flow in a resistor 4 thereby damping the oscillations in the installation caused by the overload or surge.
