Title: Apparatus for detecting rotational angle
Inventor: TAKEUCHI SHUICHI
IPC: G01D5/249
Filed: 2001-07-16
Abstract: A relative rotational angle of a rotary body (7) is measured with respect to a reference angle. First openings (11) are arranged about the circumference of a disk (5), which rotates integrally with the rotary body (7), at a predetermined pitche. A first detecting element (21) detects the first openings (11) and generates a first two-bit binary code. The relative rotational angle of the rotary body (7) is computed in accordance with the first binary code. A second detecting element (20) detects second openings (12) and generates a second one-bit binary code. The reference angle of the rotary body (7) is computed and reset in accordance with the second binary code. Third openings (13) are concentric with the first and second openings. A third detecting element (22) detects the third openings (13) and generates a third two-bit binary code. The reference angle is determined based on the combination of the first and third binary codes.

Title: Trench oxide structure having rounded corners
Inventor: MA YI
IPC: H01L27/08
Filed: 2001-08-29
Abstract: A pad oxide layer 44 and a silicon nitride layer 46 are formed on a semiconductor layer 12, and a trench 48 is formed by anisotropic etching. The pad oxide 44 is etched using HF to form a recess 50 exposing the top surface of the semiconductor layer adjacent to the trench. Subsequently an angled implant 54 of an oxidation enhancing species into the walls 30 of the trench is performed, in the region of the upper trench corners (34). The oxidation enhancing species may be oxygen, silicon, helium or argon. The trench is then oxidised with a relatively low thermal budget, such as 1100{C for 5 minutes. Due to the selective implant of the oxidation enhancing species, the oxidation causes the upper corner of the trench (34) to have a greater radius of curvature than the lower corner of the trench (38). Consequently, the intensity of electric fields generated about the trench structure are reduced.

Title: A device for removing weed plants from the soil
Inventor: BUTTERS IVAN WILLIAM
IPC: A01B1/16
Filed: 2002-01-24
Abstract: A hand tool with a handle fitted with two or more prongs 19 which engage with the plant in the soil. The prongs are loosely mounted allowing both lateral and axial movement. In use the device is pushed into the soil with the prongs either side of the plant. The operator rotates the handle, causing the prongs to effectively grip the weed, and pulls on the tool to remove the plant from the soil. A further embodiment is described in which a hand operated lever 27 attached near to the handle connects to the prongs by a cable 25. Lifting of the handle sets up tension in the cable causing the prongs to be moved into a relatively rigid or non-moving position. The prongs may have grooves around the cylindrical shaped body, or grooves lengthwise along the structure. They may have pointed or rounded tips.

Title: Mobile communications apparatus including GPS
Inventor: PRATT ANTHONY RICHARD
IPC: G01S1/00
Filed: 2002-04-24
Abstract: In a mobile unit housing a two-way communications subsystem and a satellite positioning system (SPS) receiver subsystem, the communications subsystem includes a training signal generator for generating a training signal mimicing a positioning signal transmitted by a remote SPS transmitter. The training signal is frequency- coupled to a reference frequency source contained within and used by the communications subsystem, which source is, itself stabilised by means of communication with a remote station, e.g. a base station in a cellular telephone system. In a training sequence, the training signal is activated and coupled into the SPS receiver subsystem, and a replica signal generator for generating a carrier replica signal for position-fixing purposes is controlled so as to bring the carrier replica signal into alignment with the training signal. Information representative of the control setting of the replica signal generator corresponding to such alignment is stored. Subsequently in a searching sequence, the training signal is deactivated and the replica signal generator is set to a setting based on the stored information for acquisition and processing of positioning signals from remote SPS transmitters.

Title: Label blank
Inventor: BRETT PAUL IAN
IPC: G09F3/04
Filed: 2003-03-04
Abstract: A blank for forming into a label for carrying information, which blank comprises a self adhesive sheet (10) having delineated thereon at least four distinct areas (13,14,15,16) in a symmetrical arrangement with a strippable backing layer (11) on the self-adhesive face of the blank. Each area has an upper surface on which data can be printed, and there are fold lines (18,19,20,21) between adjacent areas. On stripping the printed blank from the backing layer and folding the blank about a fold line coincident with the axis of symmetry, the self-adhesive faces are brought into contact with each other thereby forming a label having half as many regions as there were areas in the blank. These regions are separated by overlying fold lines, about which the regions may be relatively folded to conceal printed information thereon.

Title: Multiple conversion tuner with reduced spuriae
Inventor: COWLEY NICHOLAS PAUL
IPC: H03J1/00
Filed: 2003-06-07
Abstract: A multiple conversion tuner comprises a plurality of cascade-connected frequency changers, each of which comprises a mixer 5,10 and a local oscillator 6, 11. The tuner also comprises a local oscillator frequency selecting circuit 23, 24 which controls the frequencies of the local oscillators 6, 11. The frequencies are controlled so that the final mixer 10 converts a desired signal to the final intermediate frequency and so that the frequency band occupied by the desired signal at the output of each mixer 5, 10 is within the passband of the following intermediate frequency part 8,13 of the tuner. The local oscillator frequencies are also chosen so that there is no signal of unacceptably large level in the frequency band of the desired signal at the final intermediate frequency resulting from mixing of an undesired signal with harmonics higher than the first harmonic of the local oscillator signals. The frequencies of the local oscillators may be controlled by look-up tables, or with reference to a bit error rate (BER) estimator circuit (33, fig 3) whose output is supplied to a tuning controller 35 (fig 3), including a tuning alignment algorithm 34, which may be implemented as part of a digital domain demodulator 20.
