Publication number: 20190315722Abstract: Provided is an additive for imparting ultraviolet absorbency, or an additive for imparting a high refractive index, which has satisfactory compatibility with a resin serving as a matrix and can maintain high transparency even if added in high concentrations. Also provided is an additive with which the function of imparting both ultraviolet absorbency and a high refractive index can be realized by means of one kind of additive. This additive is represented by the following Formula (I): wherein at least one of R1a to R9a is a monovalent sulfur-containing group represented by the following Formula (i-1) or Formula (i-2): ?R10a?mSH??(i-1) ?R11a?nS?R12a—S?pR13a??(i-2) wherein R10a to R12a each represent a divalent hydrocarbon group or the like; and R13a represents a monovalent hydrocarbon group or the like.Type: ApplicationFiled: April 25, 2019Publication date: October 17, 2019Applicants: Miyoshi Oil & Fat Co., Ltd., Tokai Optical Co., Ltd.Inventors: Koji KAWAI, Kotaro KANEKO, Nobuhiro KANEKO, Yuichi SHISHINO, Kuniyoshi OKAMOTO

Patent number: 10432108Abstract: A power supply system that includes a converter that converts an input alternating-current voltage into a direct-current voltage and outputs the direct-current voltage to a load. The system includes a switcher that electrically connects one of multiple alternating-current power supplies to the converter, a voltage detector that detects an input voltage input to the converter, and a current detector that detects an output current output from the converter. The switcher repeats, for a predetermined amount of time, a determination of whether there is an abnormality in alternating-current power supply based on the input voltage detected by the voltage detector. Moreover, if there is an abnormality, the switcher switches which alternating-current power supply is connected to the converter. Further, the switcher adjusts, based on the result of detection by the current detector, the amount of time for which the determination is performed.Type: GrantFiled: February 15, 2019Date of Patent: October 1, 2019Assignee: MURATA MANUFACTURING CO., LTD.Inventor: Koji Kawai
