  • Patent number: 7826728
    Abstract: The image processing system is applied to dentistry, for example, and performs photography of the teeth of a patient while causing a plurality of illumination light LEDs of different wavelengths to emit light by means of a photography device when producing a crown repair or denture of the patient, whereby image data are acquired. The image data are transmitted to a dental filing system constituting a processing device where color reproduction data are determined through computation. In addition, color reproduction data are transmitted to the dental technician's office via a public switched network. Therefore, a repair material compound ratio calculation database is searched and the compound data for a material that matches the hue of the patient's teeth are found, whereby a crown repair or denture or the like that very closely matches the color of the patient's teeth is produced.

  • Patent number: 7819389
    Abstract: An engagement chain type hoisting and lowering device is disclosed, having a hoisting and lowering table attached to the upper end of two or more pairs of hoisting and lowering driving engagement chains. A driving motor drives two pairs of hoisting and lowering sprockets which, in turn, raise or lower two pairs of hoisting and lowering driving engagement chains. By arranging two pairs of hoisting and lowering driving engagement chains on two opposed sides of the hoisting and lowering table, buckling of the hoisting and lowering driving engagement chains is suppressed, resulting in stable hoisting and lowering operations without slippage of articles on the hoisting and lowering table, and chain endurance is improved. The device is designed so that the lowest position of the hoisting and lowering table can be lower than the height of the peripherally located driving motor, for ease and safety of operation and maintenance.
