Tokuhide Shimojyo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Light-emitting device having a recessed portion in rear panel thereof
    Patent number: 5844358
    Abstract: A light emitting device is provided including a front panel on which fluorescent elements are arranged in a matrix form and a rear panel onwhich cathodes are arranged in a corresponding relation to the fluorescent elements. The cathodes emit thermoelectrons for causing the fluorescent elements to emit light, and a square frame-like spacer is provided, one opening portionof the spacer being covered with the front panel and the other opening portion thereof covered with the rear panel. A stepped portion for fitting with the spacer is formed in a position of the rear panel to be bonded with the spacer.

  • Light emitting device resistant to damage by thermal expansion
    Patent number: 5406170
    Abstract: The present invention relates to light emitting devices which emit light upon impingement of thermoelectrons on a front panel having fluorescent elements and where an array of cathodes and electrodes are provided on a substrate within each light emitting device. Thus, in the present invention, first electrode leads having a coefficient of thermal expansion substantially equal to that of the substrate are inserted into and through the substrate, and second electrode leads having a coefficient of thermal expansion substantially equal to that of the rear panel are inserted into and through the rear panel, and the first and second electrode leads are connected such that the substrate is supported at a distance above the rear panel.

  • Method of forming a light emitting device
    Patent number: 5304083
    Abstract: The present invention relates to a light emitting device which emits light upon impingement of thermoelectrons on a front panel having fluorescent elements. In each bonding surface of a spacer which is bonded to both front and rear panels, a positional deviation or displacement of the spacer with respect to the front panel, the rear panel or a shielding electrode is prevented, whereby there is obtained a light emitting device of high accuracy free of variations in luminance, and it is made possible to reduce a dead space between adjacent light emitting devices and thereby attain a display of high resolution. In order to obtain such display, the front panel and the spacer, as well as the rear panel and the spacer, are respectively bonded through premolded frit glass.
