Patent GB-2247703-A (GB)
Title: Positioning and levelling base
Inventor: COE DAVID ARTHUR
IPC: E04H12/22
Filed: 1991-10-28
Abstract: A base assembly for the foot of a vertical column (39) in e.g. a pergola, garden arbour or like structure adjusts during assembly from a nominal to a specific verticality and placement and thereby avoids placement stresses in the structure being erected. One embodiment has a fixing cylinder (23), driven into the earth, carrying a fixed cruciform datum support (27, 28) with eight threaded holes, four referenced as at (30) and four as at (29). The cylinder is hammered in. Flat-head support screws (21) are screwed into holes (30). Plate (2) is laid upon the heads of screws (21). Screws (22) are loosely connected in holes (29). Cylinder (23) is turned so that slot (11) in plate (2) orients in the desired direction, so that bolt (19) can locate as desired along the slot (bar (27) prevents its fall). The plate (2) is levelled by turning screws (21) via holes (10), and then secured firmly by screws (22) to leave bolt (19) protruding accurately vertically and in an exact desired position, but incapable of rotation because its head is caught in a recess around slot (11). A base fitment (32) can then be fitted over bolt (19) to receive the tapered lower end of column (39).

Title: Bipolar/unipolar-drive back-emf communication sensing method
Inventor: PETERS DAVID H
IPC: H02P6/18
Filed: 1991-11-06
Abstract: Apparatus to commutate the drive voltages of a brush loss DC motor without sensors has the rotor position and velocity determined by detecting the polarity reversal of the Back-EMF of an undriven leg when compared to a transformed reference. The Back EMF detection is determined by a resistive divider 56, 116 coupled to a centre tap of the motor and further resistive dividers 53-55 and 113-115 coupled to respective legs of the motor winding, in a network 93a, which is coupled to Back EMF comparators 42-44. A line 99 enables selection of unipolar or bipolar operation by means of a power switch 96 and NAND gates 27a. 28a and 29a. In an extra measure of efficiency, the apparatus includes a commutation delay timing circuit 95 for optimization of motor operation, and it minimizes the participation of a microprocessor or other microcontroller. <IMAGE>

Title: Diamond field-effect transistor and method for making same
Inventor: DAS KALYANKUMAR
IPC: H01L29/45
Filed: 1992-08-13
Abstract: An insulated gate field-effect transistor including an active diamond layer (20) has a desired boron doping concentration profile generally decreasing with increasing depth in the diamond layer produced by ion implantation at nominal room temperature or at slightly higher temperatures within the operating range of commercially available ion implantation equipment. The boron ion implantation is followed by an annealing which forms a graphite layer at the surface portion of the diamond layer. The graphite layer is removed by a chemical etching leaving a relatively high boron doping concentration at the exposed surface of the diamond layer. Low resistance ohmic contacts can readily be formed on the highly-doped surface, and are bilayers of gold (326) on refractory metal (32a). An insulated gate electrode (36) is formed on the highly doped surface and provides a low gate leakage current and passivates the surface of the diamond layer. <IMAGE>
