  • Publication number: 20040130496
    Abstract: A diversity antenna system of the present invention includes: two antennas of different directionality, the two antennas generating two signals; a synthesizing means for generating a synthesized signal by synthesizing the two signals; a selection means for selecting either one selected from the group consisting of the two signals and the synthesized signal; and a selection controlling means for controlling the selection means. When the intensities of the two signals are not higher than a predetermined value, the selection controlling means controls the selection means such that the selection means fixedly selects the synthesized signal. According to the diversity antenna, excellent receptive conditions can be obtained even in weak electric fields.

  • Patent number: 6132046
    Abstract: In an ophthalmologic apparatus which can start a measurement or a photographing operation with respect to an eye to be examined by suitably making an automatic alignment with a cornea of the eye as a center, When a diseased eye is to be measured, slight reflected light (e.g., cornea scattering light) except for reflected light from a vertex of the cornea of the eye is interrupted by an XY alignment detecting stop even when this slight reflected light is detected by a position detecting sensor. Accordingly, since no slight reflected light is almost incident to a light quantity detecting sensor, the XY alignment light quantity detecting circuit does not output an alignment completion signal to a control circuit. Thus, the control circuit performs a control operation such that the measurement or the photographing operation with respect to the eye is not performed.

  • Patent number: 6121934
    Abstract: A glass antenna device for a vehicle includes an FM antenna (as a receiving antenna for short-waves) and a defogger provided on a rear window glass of the vehicle, and an AM antenna (as a receiving antenna for medium-waves) provided on a side window glass fixed at a different position from the rear window glass of the vehicle. Since the AM antenna is spaced relatively far distant from electric equipments such as a rear wiper, stop lamps and indicators disposed at a rear portion of the vehicle, noises generated from the electric equipments are unlikely to be mixed in a transmission line of the antenna device.

  • Patent number: 5910833
    Abstract: A stopper knob (108) is provided on the side surface of a base (101). If a joy stick (107) is tilted forward lowering the stopper knob (108), a platform frame (109) advances, and the main body of an instrument can be roughly aligned with a subject eye to be tested. If the alignment is completed, the stopper knob (108) is released. In the ophthalmic instrument of the present invention, automatic alignment which performs precise alignment on the subject eye is not started by only releasing the stopper knob (108). The ophthalmic instrument is provided with a microswitch (111). When the platform frame (109) is pulled on a tester's side by the joy stick (operating stick) (107) and the microswitch (111) engages with a protruding portion (112) fixed to the base (101), automatic alignment is started.

  • Patent number: 5724252
    Abstract: In the prediction of side-chain conformation of protein, conformations are predicted by describing a candidate conformation in the form of an array whose components are the torsion angles of a side chain, subjecting a plurality of solution candidates to evaluation, increasing side chains in a stepwise manner, judging the appropriateness of a solution candidate based upon degree of its van der Waals contact, and generating a new solution candidate by changing torsion angle to an arbitrary value or by interchanging the components of the torsion-angle arrays of two solution candidates. Further, the foregoing processing is executed with respect to the main-chain conformation whenever a side-chain conformation corresponding to one amino acid residue is constructed, and construction of all side-chain conformations is performed in incremental fashion.
