  • Patent number: 8450764
    Abstract: A light-emitting apparatus has a light-emitting device and a supporting board. The light-emitting device has a pair of n-electrodes with a p-electrode therebetween, on the same plane. The supporting board includes an insulating substrate on which positive and negative electrodes are formed, opposing to the p- and n-electrodes of the light-emitting device, respectively. Bonding members bond the p- and n-electrodes with the positive and negative electrodes, respectively. The positive electrode on the supporting board is formed within the width region of the p-electrode and narrower in width than the width of the p-electrode, in a cross-section along a line extending through the pair of n-electrodes. The negative electrodes oppose to the n-electrodes, respectively, with the same widths, or with that side face of each of the negative electrodes which faces the positive electrode being retracted outwardly from that side face of each of the n-electrodes which faces the p-electrode.

  • Patent number: 5105267
    Abstract: A color conversion apparatus in use with a digital image processing sysetm in which image data is represented by digital data of three separated colors. The apparatus has a colorimetric system converter for separately converting the separated color data into chromaticity data and value data and a designating device for designating an original color and a converted color. A discrimination device discriminates whether or not the chromaticity data from the colorimetric system converter is coincident with the chromaticity data of an original color designated by the designating device. A selecting device selects one of the chromaticity data from the colorimetric system converter and the chromaticity data of an original color designated by the designating device on the basis of the discrimination result.
