  • Publication number: 20050088690
    Abstract: Original images, large images, medium images and thumbnail images are registered with a server system. An original-image file is transmitted from a client computer to the server system. The server system converts the format of the original-image file to generate a large-image file, generates a medium-image file, in which the quantity of data is less than that of the large-image file, from the large-image file, and generates a thumbnail-image file, in which the quantity of data is less than that of the medium-image file, from the medium-image file. The original-image file, large-image file, medium-image file and thumbnail-image file are placed on one folder and stored in an image file unit. After the folder containing the original-image file, etc., has been stored in the image file unit, the user of a client computer having access privileges is capable of accessing files such as the large-image file.

  • Patent number: 6674197
    Abstract: An electromagnetic sound generator is proposed that can be easily and inexpensively fabricated for producing an indicating sound to enable use in an automobile or other similar environment. A spool (2) on which a coil (3) has been wound, a core (4) that is movable up and down, and a round spring (5) are installed inside a cup-shaped yoke (1); whereby supplying or cutting off the supply of current to the coil (3) causes the core (4) to strike, in single beats in accordance with drive, against the yoke (1) itself or on the side of spring (5) to produce a sound. The yoke (1), which is the magnetic circuit for driving, also serves as a sound generator, and the provision of openings such as slits in the upper surface and side surfaces of the cup-shaped yoke (1) enhances sound effects such as the tone, volume and direction of emission of the generated sound.

  • Patent number: 6621521
    Abstract: An image recorded on photo film is projected through an imaging lens onto an image sensor. In accordance with a selected mode, set values are read out from a data ROM and are applied to a band pass filter consisting of programmable digital filters. Pixel signals from the image sensor are converted into evaluation signals which are correlative with spatial frequencies of the image, and are filtered through the band pass filter with the frequency band determined by the set values. The evaluation signals are integrated, and a peak value of integration values obtained at different focusing positions is determined to be an in-focus position.

  • Patent number: 5428695
    Abstract: An optical non-reciprocal circuit is constituted by a channel waveguide, a planar waveguide, and a diffraction lattice or grating. The channel waveguide is disposed in a planar substrate that is transmissive to optical waves. The planar waveguide is disposed on only one side of a substrate plane divided by the channel waveguide in the substrate plane and having an equivalent refractive index lower than that in the channel waveguide. The diffraction grating provides a spatial periodic change of the refractive index to a guided optical wave of the channel waveguide. The periodicity of the lattice direction, that is, the direction of the wavenumber vector is neither parallel nor perpendicular to the optical transmission direction of the channel waveguide but is given a finite angle. The optical non-reciprocal circuit can be realized by using only an ordinary dielectric material with the circuit being highly productive and low priced and having high performance.

  • Patent number: 5294790
    Abstract: A hole is formed in a silicon substrate, passing through the substrate. An insulating film is formed on one face of the silicon substrate and one open end of the hole is thus closed by the insulating film. An antireflection film is attached to that area of the insulating film by which the one open end of the hole is closed. An optical fiber is fitted and fixed in the hole. An optically-transparent conical probe is formed on the area of the insulating film which corresponds to the hole in the silicon substrate and the probe is coated by a metal film while leaving a tip of the probe not coated. A fine aperture is thus formed at the tip of the probe to allow light to enter into the probe through the fine aperture. The metal film prevents light reflected from entering into the probe and light from being leaked from the probe, and it is connected to an electrode to use tunnel current to position the fine aperture near a sample.
