Patent number: 10965211Abstract: A technology for suppressing a performance degradation of a solar battery caused by PID is provided. A conversion device includes a DC/DC converter and a control part. A solar battery is connected to an input end of the DC/DC converter. When direct-current power generated by the solar battery is converted and output, the DC/DC converter makes a potential of a negative electrode of the solar battery to be higher than a potential in a negative electrode of the output when the power input from the solar battery exceeds a prescribed value. The control part changes a voltage of the power output from the solar battery to detect a peak value of the power, and stops the operation of the DC/DC converter when the peak value is smaller than the prescribed value.Type: GrantFiled: January 18, 2019Date of Patent: March 30, 2021Assignee: OMRON CorporationInventors: Hirokazu Ehara, Kazumi Tsuchimichi, Kenji Kobayashi, Yasuhiro Tsubota

Patent number: 10340845Abstract: A voltage transform part transforms the direct-current power input to an input part. A first input and output part outputs the transformed direct-current power to a battery unit and to which direct-current power is input from the battery unit. A conversion part converts the direct-current power input to the input part into alternating-current power. A second input and output part outputs the alternating-current power to a power system or a load and to which an alternating-current power is input from the power system. The conversion part converts the alternating-current power input to the second input and output part into direct-current power. The second voltage transform part transforms the direct-current power converted by the conversion part and transforms the direct-current power input to the first input and output part. The conversion part converts the direct-current power transformed by the second voltage transform part into alternating-current power.Type: GrantFiled: September 13, 2018Date of Patent: July 2, 2019Assignee: OMRON CorporationInventors: Atsuo Minato, Katsumi Ohashi, Arata Yoneda, Kazumi Tsuchimichi, Katsutaka Tanabe, Junichiro Yamada, Yasuhiro Tsubota

Publication number: 20060187444Abstract: The measurement light radiated from a radiator 2 enters an object of inspection through an integrating sphere 22. The measurement light is reflected on a base 52 of the object or a thin film 54. Further, the reflected light enters the integrating sphere 22 and is equalized in the integrating sphere 22. After that, the equalized reflected light is led to a light splitter 12 through an optical fiber 10. The light splitter 12 splits the reflected light in the order of wavelength, and applies an electrical signal corresponding to the intensity spectrum to an arithmetic processor 14. The arithmetic processor 14 determines the state of the thin film 54 formed on the surface of the object based on the electrical signal received from the light splitter 12.Type: ApplicationFiled: February 1, 2006Publication date: August 24, 2006Inventors: Kazumi Tsuchimichi, Takeshi Takakura
