Title: Antenna system
Inventor: KOSAKAI OSAMU
IPC: H01Q1/24
Filed: 2000-02-28
Abstract: PROBLEM TO BE SOLVED: To provide an antenna system that induces no current in a wireless circuit board, while ensuring a sufficient antenna occupied area. SOLUTION: A radiation conductor 16 is adhered to the outer surface of an enclosure 12 of a portable wireless unit 11, the radiation conductor 16 and a wireless circuit of a wireless circuit board 13 placed in the enclosure 12 are coupled with a capacitance, formed between a capacitance board 15 and the radiation conductor 16 and the wireless circuit supplies power fed from the wireless circuit board 13 to the radiation conductor 16. Since the radiation conductor 16 has an electric length of about nλ/2 (n=1, 2, 3 and so on), no current is induced on the wireless circuit board 13 and no characteristic deterioration due to the effect of a human body is caused.  Furthermore, since the radiation conductor 16 is channel-shaped, a main polarized wave becomes a horizontally polarized wave, and even when the portable wireless unit 11 is tilted by about 60 degrees, a satisfactory characteristic with less polarized wave mismatching can be obtained.

IPC: G01N33/20
Filed: 2000-02-29
Abstract: PROBLEM TO BE SOLVED: To measure the composition and the particle diameter of a non-metal foreign materials which exist in steel or non-ferrous metals. SOLUTION: The composition and/or particle diameter of non-metal foreign matters existing on the surface of metal and/or inside it are determined by a laser excitated-ICP analysis method. Preferably, a sample or a large mass sample, cut out of steel or non-ferrous metal, is irradiated with a laser light to evaporate the foreign matters, and then undergoes ionization in a high temperature inductively coupled plasma. Thus, the number of ions generated is measured by a mass spectrometer or an emission spectrophotometer to determine a peak attributed to the foreign matters for elements by integration processing from a time curve of spectrum.

Title: Optical disk device
Inventor: WATANABE KATSUYA
IPC: G11B7/09
Filed: 2000-03-02
Abstract: PROBLEM TO BE SOLVED: To perform tracking control with a high degree of reliability by driving a moving part of an optical head and controlling it so that a light beam correctly scans on the track according to an output signal of a phase difference track deviation detecting part for converting the deviation into a signal corresponding to a positional relation between the optical beam and the track. SOLUTION: Reflected light from a disk 101 is made incident to 4-split photo- detector 114 via a condenser lens 113. A matrix computing element 116 calculates sums of various combinations of the detecting parts A-D of the 4-split photo-detector 114, and generates a phase difference tracking error signal (signal TE). An A/D 112 converts the signal TE, and inputs a signal phTE to a DSP 132, and the DSP 132 outputs a signal TRD and makes a current flow through a tracking actuator 103 via a synthesizing circuit 133 and a driving circuit 134. The converging lens 105 is driven in the tracking direction, and tracking control is performed so that a light beam pot 107 correctly scans the tracks.
