Title: Gunn diode
Inventor: NEWSOME KEITH DAVID
IPC: H01L47/02
Filed: 2006-03-29
Abstract: A Gunn diode (Figure 4) having axis A consists of appropriately doped layers which, when a suitable voltage is applied, cause a space charge 6 to traverse a transit region 7 at a microwave frequency. In a typical known Gunn diode, the layers 4, 5 and 7 to 9 extend across the full diameter of the diode, and the space charge 6 is usually depicted as being disc-shaped. There is the disadvantage that the d.c. component of the Gunn effect current associated with a desired harmonic frequency causes undesirable heating. According to the invention, the area through which the current can flow through the elongate structure is tailored to favour the harmonic over the d.c. component, utilising the skin effect. Several ways of doing this are described, notably by making the core 10 of the elongate portion non-conducting, for example, by ion implantation or by its removal by etching.

Title: Downhole signaling using a sparker
Inventor: MISZEWSKI ANTONI
IPC: E21B47/09
Filed: 2007-09-14
Abstract: A downhole tool 10 includes means for detecting a downhole condition, a capacitor bank, and a sparker. The technique is particularly useful for detecting casing collars. As the tool 10 is passed along the well bore 11, it detects collars 12. On each detection, a part of the capacitor bank is discharged through the sparker. This generates an acoustic pulse which is transmitted through the ground (wave 14) to detectors 15, 16. The movement of the tool 10 is also monitored by a movement detector 20. The position of the tool 10 is correlated with the positions of the collars 12 by a computer 22 fed via interfacing circuitry 21. If desired, the pulses may be coded by strength, number, time spacing, etc.
