Patent number: 6576302Abstract: There is disclosed a method for producing a metal oxide, which comprises the steps of: dissolving a metal organic compound (e.g. a metal organic acid salt, a metal acetylacetonato complex, and a metal alkoxide having an organic group with 6 or more carbon atoms) in a solvent to provide a state of solution, applying the solution onto a substrate, drying the solution, and subjecting the resultant substrate to irradiation with a laser light of a 400 nm or less wavelength, to form a metal oxide on the substrate. According to that method, a metal oxide can be produced without applying a heat treatment at a high temperature of the degree adopted in the conventionally known application thermal decomposition method.Type: GrantFiled: February 25, 2000Date of Patent: June 10, 2003Assignee: Agency of Industrial Science and TechnologyInventors: Susumu Mizuta, Tetsuo Tsuchiya, Akio Watanabe, Yoji Imai, Iwao Yamaguchi, Toshiya Kumagai, Takaaki Manabe, Hiroyuki Niino, Akira Yabe

Patent number: 4950068Abstract: An apparatus for detecting ophthalmic diseases in a patient's eye includes light projection system for projecting a laser beam at a spot in the eye. The light scattered from the eye is photoelectrically detected and converted into an electrical signal which is subsequently used to determine the protein concentration essential to ophthalmic disease detection. A monitor is provided in the light projection system for monitoring light scattered from the cornea of the eye on which the laser beam is projected, and for monitoring a virtual image which is formed by the cornea surface from light scattered at the exit window of the light projection system to correctly position and align the apparatus in order to ensure accurate protein concentration measurements.Type: GrantFiled: July 7, 1988Date of Patent: August 21, 1990Assignee: Kowa Company Ltd.Inventor: Susumu Mizuta

Patent number: 4941741Abstract: An apparatus for detecting ophthalmic diseases, such as inflammation in a patient's eye, includes a projection system for projecting and focusing a laser beam at a selected spot in the eye. The laser light scattered from the eye is photoelectrically detected through a slit in a mask and converted into an electrical signal which is used to determine the protein concentration in the patient's eye. A light shield member is displaceable in front of the mask slit to selectively block diffused light from the eye or scattered laser light to improve the S/N ratio of the electrical signal.Type: GrantFiled: July 7, 1988Date of Patent: July 17, 1990Assignee: Kowa Company, Ltd.Inventor: Susumu Mizuta
