Title: Adaptive fuzzy logic temperature control
Inventor: TSUI WILLIAM TAK MING
IPC: G05D23/19
Filed: 2003-05-06
Abstract: Fluid temperature control is achieved by using fuzzy logic rules sets to derive values of integral gain KI and proportional gain KP for use in a proportional-integral temperature controller operable to generate a valve control signal v(t) representing a magnitude of an opening in a inlet valve of a heat exchanger operable to regulate the temperature of the fluid under control of the proportional-integral controller. The fuzzy rules sets have as inputs fuzzy representations of signals derived from the valve control signal v(t) and a signal e(t) representing an error in temperature between an actual measured temperature of the fluid and a desired temperature of the fluid. A fuzzy logic control module associated with the proportional-integral controller can implement the fuzzy logic rules sets. The fluid may be, for example, dye in a textiles dyeing process.

Patent TW-200402146-A (TW)
Title: Photodetector circuits
Inventor: MARSHALL GILLIAN FIONA
IPC: H01L31/02
Filed: 2003-07-10
Abstract: A photodetector circuit incorporates an APD detector structure 10 comprising a p- silicon handle wafer 12 on which a SiO2 insulation layer 14 is deposited in known manner. During manufacture a circular opening 16 is formed through the insulation layer 14 by conventional photolithography and etching, and an annular p+ substrate contact ring 18 is implanted in the handle wafer 12 after opening of the window 16. The APD itself is formed by implantation of a p region 20 and an n+ region 22. After the various implantation steps a metallisation layer is applied, and annular metal contacts are formed by the application of suitable photolithography and etching steps, these contacts comprising an annular contact 26 constituting the negative terminal and connected to the p+ substrate contact ring 18, an annular metal contact 28 constituting the positive terminal and connected to the n+ region 22 of the APD, and source and drain contacts 30 and 32 (not shown in Figure 1) connected to the source and drain of one or more CMOS MOSFET devices of the associated CMOS readout circuitry fabricated within a Si layer 34 formed on top of the insulation layer 14. Such an arrangement overcomes the problem of combining APDs with CMOS circuits in that APDs operate at relatively high reverse bias (15-30V) and CMOS circuits operate at low voltage (5V), and the arrangement must be such as to prevent the high bias voltage from affecting the operation of adjacent CMOS transistors.

Filed: 2003-07-31
Abstract: Disclosed is an extrusion forming method of a self-locking nut, which includes the following steps that are performed on a nut forming machine with a mold: A billet is trimmed. A trimming process is then adopted where the trimmed billet is then reconditioned to the predetermined dimensions. A flange forming process is then adopted where the reconditioned billet is then formed at an end thereof with a flange. A flange tuning and teeth forming process is then adopted where the flange is then further tuned to a predetermined length and teeth are then formed on the perimeter of the flange along its axial direction to form aligned teeth. The billet that is formed by adopting the above processes is then subject to a bore punching process to form a bore along the axial direction. Threads are then formed to the bore. The above method in cooperation with the mold allows rapid extrusion forming of self-locking nuts.

Title: Offset compensation circuit compensating for offset voltage of drive circuit as well as drive circuit with offset-compensation capability and liquid-crystal display device using the offset compensation circuit
Inventor: TOBITA YOUICHI
IPC: H03K5/22
Filed: 2004-03-03
Abstract: An offset-compensation drive circuit turns on first, second and third switches to charge a first capacitor to an offset voltage of a drive circuit, and thereafter turns off the first and second switches and turns on a fourth switch to charge a second capacitor to a first voltage loss caused by a parasitic capacitor of an input node of the drive circuit. Following this, the third and fourth switches are turned off and fifth and sixth switches are turned on. At this time as well, there occurs a second voltage loss due to the parasitic capacitor and thus an output voltage is equal to a difference between an input voltage and the second voltage loss. Supposing that the parasitic capacitor, the first capacitor and the second capacitor have the same capacitance value, the second voltage loss is one-sixth as large as the first voltage loss.
