  • Patent number: 6016435
    Abstract: A device for non-invasive determination of a glucose concentration in the blood of a subject which includes a light source for producing near-infrared radiation having successive wavelengths within a range of 1300 nm to 2500 nm, a light projecting unit for projecting the near-infrared radiation on a skin of the subject, a light receiving unit for receiving a resulting radiation emitted from the inside of the skin, and a spectrum analyzing unit for making a spectrum analysis of the resulting radiation, and determining the glucose concentration according to the spectrum analysis. The light receiving unit is separated from the light projecting unit by a distance defined within a range of 0.1 mm to 2 mm to selectively sense the resulting radiation emitted from a dermis layer positioned under an epidermis layer of the skin.

  • Patent number: 5957841
    Abstract: A glucose concentration in a living tissue as a target is determined by the following method. Near-infrared radiation is projected on the living tissue, and a resulting radiation emitted from the living tissue is received. A spectrum analysis of the resulting radiation is performed to detect a first absorption signal from a wavelength region, e.g., 1550 nm to 1650 nm, having an absorption peak of OH group derived from glucose molecule, a second absorption signal from a wavelength region, e.g., 1480 nm to 1550 nm, having an absorption peak of NH group in the living tissue, and a third absorption signal from a wavelength region, e.g., 1650 nm to 1880 nm, having an absorption peak of CH group in the living tissue. The glucose concentration is determined by a multivariate analysis of results of the spectrum analysis, in which the first, second and third absorption signals are used as explanatory variables, and the glucose concentration is a criterion variable.

  • Patent number: 5644411
    Abstract: An image processing apparatus includes a joining-portion processing section for combining partial images that have been read in a divided manner. Focused on partial document data predeterminately specified among a plurality of partial document data stored in an image memory, the joint-portion processing section performs a recognizing operation on the joints, a positioning operation and other operations beginning with the proximity of the specified partial document data. The partial images are then combined together to form one complete image. For example, in the case of copying an original document, which is of a size too large to be copied in one operation, on one sheet of paper in a reduced manner, it becomes possible to eliminate time consuming tasks such as trimming and pasting of the partial documents as well as calculating of the reduction rate.

  • Patent number: 5296896
    Abstract: An image forming apparatus including a condition determining device for determining optimum conditions automatically for copying a document during copying, a blank lamp for recording information concerning the determined conditions in code on a sheet of copy paper, a code scanner for reading the coded information when producing a copy from the copy paper carrying the code thereon, and control circuits for setting copying conditions according to the read information. With this configuration, when producing copies of the image on the original document, by reading the coded information and setting the copying conditions, an image satisfying the optimum conditions is readily obtained whenever it is desired. Moreover, even when making copies from a copied image which was produced through subsequent copying, the formed images always have the same quality that the original has.

  • Patent number: 5288559
    Abstract: Provided is a coating composition for a two-piece can containing a polyester resin (A) consisting essentially of terephthalic acid and propylene glycol and containing tri- or more functional polycarboxylic acid or polyol comonomer(s) and an alkyl-etherified aminoformaldehyde resin (B); and the coating film (C) to be obtained by reacting these (A) and (B) in the composition has larger tensile strength and elongation than the film made of only (A). The coating composition is coated on at least one surface of a metal sheet to give a coated metal sheet for a two-piece can. The coated metal sheet may be formed into a drawn and ironed can or a drawn and re-drawn can. The adhesiveness of the coated film to the metal sheet is high, and the coated film has excellent resistance to blistering and resistance to whitening and has excellent flavor preservability.
