  • Patent number: 6432439
    Abstract: An O/W emulsion composition comprising fluorometholone or clobetasone butyrate, a phospholipid, an oil, a nonionic water-soluble cellulose derivative, and water. The O/W composition has advantages that fluorometholone or clobetasone butyrate contained therein is highly bioavailable and that the solubility of fluorometholone or clobetasone butyrate and the concentration thereof present in the composition can be kept stable. Thus, this composition is usable for the treatment of various inflammatory diseases by the generalized or local administration thereof. It provides a drug which shows an anti-inflammatory activity equal or higher than that of commercially available eye drops comprising a suspension of such an active ingredient even when it is applied in a smaller dose than that of commercially available one and further provides a drug having excellent storability, which reduces apprehension of systemic side effects of fluorometholone or clobetasone butyrate when it is applied to the eyes.

  • Patent number: 6132751
    Abstract: An O/W emulsion composition for eye drops comprises a drug selected from the group consisting of fluorometholone, clobetasone butyrate and clobetasol propionate; a phospholipid; liquid paraffine; and water. The O/W emulsion composition is excellent in solubility of fluorometholone, clobetasone butyrate and clobetasol propionate in the tear fluid. Therefore, the composition would exhibit an anti-inflammatory activity identical to or superior to those achieved by the conventional pharmaceutical preparations, by the administration thereof at a dose lower than those for these known drugs. The composition would also be excellent from the economical standpoint and permit reduction of systemic side effects which would be encountered when the conventional drugs are instilled in the eyes.

  • Patent number: 6002811
    Abstract: The image scaling processing device distinguishes whether an original image data is a character image or a half-tone image per a pixel unit in the image domain separating portion and scales each image in the character scaling processing portion and the half-tone scaling processing portion. In order to get a desired scale factor L times image data, the character scaling processing is performed by the first scaling processing for enlarging an image data by 2.sup.n times (n is an integer, L<2.sup.n) in each sub scanning direction and main scanning direction and by the second scaling processing for reducing by L/2.sup.n times the image data enlarged by 2.sup.n times and the half-tone scaling processing is made by the first scaling processing for enlarging an image data by 2.sup.n times (n is an integer, L>2.sup.n) in each sub scanning direction and main scanning direction and by the second scaling processing for enlarging by L/2.sup.n times the image data enlarged by 2.sup.n times.

  • Patent number: 5693337
    Abstract: A lipid emulsion which comprises (A) an oil component, (B) an emulsifying agent containing yolk lecithin and/or soybean lecithin, and (C) water, wherein the lipid emulsion further comprises citric acid or a pharmaceutically acceptable salt thereof and at least one member selected from the group consisting of methionine, phenylalanine, serine, histidine and pharmaceutically acceptable salts thereof, provided that it does not simultaneously contain methionine and phenylalanine. The addition of citric acid and histidine, methionine, phenylalanine and/or serine to a lipid emulsion containing natural lecithin as an emulsifying agent permits the prevention of change of color and formation of oil drops associated with the conventional natural lecithin-containing lipid emulsion due to the synergistic effect of the foregoing additives.

  • Patent number: 5305057
    Abstract: In an electrophotographic image forming apparatus, a charger sensitizes the photoconductor at a desired initial potential and the photoconductor is exposed to form an electrostatic latent image, which is developed by a developer to form a toner image. A gradation correction table on the relation of the input image signal to the exposure amount is provided in a memory, and it is amended by adding a common amendment value to the image density signal in the gradation correction table. The common amendment value is determined according to the density of a standard toner image. If a plurality of gradation correction tables are stored in a memory, one of them is selected according to the output voltage of the charger or the bias potential of the developer. The selected gradation correction table is amended according to the surface potential of the photoconductor, the temperature of the photoconductor or the humidity of the photoconductor.
