  • Patent number: 7054397
    Abstract: A mobile communication system has a plurality of mobile stations and a base station which includes a plurality of antennas, a frequency shift portion, a combining portion, a receiving portion and a signal processing portion. The antenna receives radio waves transmitted by the mobile stations. The frequency shift portion shifts the received signal with a frequency corresponding to each of the antennas. The combining portion determines the shifted signal as a combining signal. The receiving portion converts the combining signal in frequency to make an intermediate frequency signal, and converts the intermediate frequency signal into a digital signal. The signal processing portion includes spreading demodulation means judging means, and fading compensation means.

  • Patent number: 6742875
    Abstract: A drop-on-demand ink-jet printing head provided with an array of a plurality of piezoelectric elements arranged at regular intervals and fixed at their one ends to a base, the other ends of the respective piezoelectric elements being free ends which are disposed in opposition to nozzle respective apertures, the piezoelectric elements being formed by cutting, at predetermined width, a piezoelectric plate obtained by firing a lamination of paste-like piezoelectric material conductive material stacked alternately in layers. Since each piezoelectric element is composed of a thin piezoelectric plate interposed between electrodes, if a voltage of only about 30 V, which is sufficient to drive the thin piezoelectric plate, is applied across the electrodes, it is possible to largely flex the whole of the piezoelectric element. By this transformation, ink between the top end of the piezoelectric element and the nozzle aperture is discharged to the outside as an ink drop.

  • Patent number: 6697397
    Abstract: The present invention comprises a dense wavelength division multiplexing system which uses an automatic level control feedback circuit or loop (100) to maintain one of a plurality of selectable output power levels. In addition, to prevent the sidelobes of the individual channels from interfering with one another when power to the channel is increased, an optical bandpass filter (5) is placed in the optical feedback path of the ALC loop (100). Furthermore, if the frequency or wavelength drifts from the desired output wavelength, the output wavelength is tuned by cooling or heating the laser using a thermoelectric cooler (55) which is part of a thermoelectric cooler loop (110) that uses a calibration table to adjust for temperature/wavelength errors.

  • Patent number: 6608495
    Abstract: A sensor enables simultaneous or sequential eddy current and optical reflectance measurements of conducting film by providing an eddy current inspection coil and a first and a second optical fiber extending axially through the coil. The eddy current inspection coil is excited by a radio frequency generator and induces eddy currents in the conducting film which are sensed using a detector. The conducting film is illuminated by a first optical fiber, and light which is reflected from the conducting film is transmitted by a second optical fiber to a detector. In the case of opaque conducting films, the eddy current sensor measures sheet resistance which is determinative of film thickness. In opaque conducting films, optical reflectance measurements are indicative of characteristics such as grain size and surface oxidation. Eddy current sensing is indicative of sheet resistance which correlates to grain size and film thickness.

  • Patent number: 6496256
    Abstract: A two dimensional sensor array is used to collect light diffracted from the inspected substrate. The signal generated by each individual sensor is passed through a threshold. Those signals which are below the threshold are amplified and are summed up. The summed signal is then passed through a second threshold. Summed signals which pass the second threshold are flagged as indicating suspect locations on the substrate. In the preferred embodiment, the entire circuitry is provided in the form of a CMOS camera which is placed in the Fourier plane of the diffracted light.
