Patent GB-8600183-D0 (GB)
Title: Joining polyolefin pipes by fusion
IPC: F16L47/02
Filed: 1986-01-06
Abstract: The apparatus increases the hydraulic pressure in rams 16 until one pipe moves towards a heater plate 14. The movement is detected by a limit switch 26 and a microprocessor-based control system 28 adds a pre-programmed value of pressure to that pressure which caused the movement (drag pressure). The total pressure is applied to force the pipe ends against a heater plate 14 to form end beads (bead-up). After heating for a pre-programmed period the control system automatically initiates plate retraction and forces the pipe ends together (fusion) for another programmed period. The applied pressure is the sum of the recorded drag pressure and a pre-programmed added pressure. Operator judgement of bead size, pressures and time periods is eliminated. Pressurised fluid is supplied to the rams 16 from a pump and accumulator combination. The sense of ram motion is determined by changeover valves controlled by the control system 28.

Title: Method of making silicon quantum wires
IPC: H01L29/06
Filed: 1992-05-01
Abstract: Luminescent silicon incorporating semiconductor quantum wires is made using a semiconductor wafer 14 as starting material. The wafer 14 is weakly doped p type with a shallow heavily doped p layer therein for current flow uniformity purposes. The wafer 14 is anodised in 20% aqueous hydrofluoric acid to produce a layer 5  mu m thick with 70% porosity and good crystallinity. The layer is subsequently etched in concentrated hydrofluoric acid, which provides a slow etch rate. The etch increases porosity to a level in the region of 80% or above. At such a level, pores overlap and isolated quantum wires are expected to form with diameters less than or equal to 3 nm. The etched layer exhibits photoluminescence emission at photon energies well above the silicon bandgap (1.1 eV) and extending into the red region (1.6 - 2.0 eV) of the visible spectrum.
