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.

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.

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.

The length of 15 mm in an axial direction of the cord means a length of 15 mm in an axial direction of an actual cord and the fraction R of the total area occupied by the filaments is expressed as R=F/A, wherein A represents the total area of the cord and F represents the area of the cord occupied by the filaments. An object of the present invention is to provide a pneumatic tire for passenger cars that shows no separation of the interface of adhesion during use, particularly during use in the run-flat condition, and exhibits excellent durability.

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.

The throttle valve and the gate valve may be actuated independently.

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.
