Patent number: 11128244Abstract: A rotation direction detecting device has a current detector detecting the direction of current flowing through a motor, a voltage detector detecting voltages before and after the motor in a power supply line, and a rotation direction detector detecting the rotation direction of the motor based on the direction of the current and the voltages before and after the motor. The current detector is connected to points A, B before and after a shunt resistor, and detects the direction of the current flowing in the power supply line to form current direction information. The voltage detector is connected to points A, C before and after the motor, and detects the voltage at each position to form motor terminal voltage information. The rotation direction detector detects the rotation direction of the motor using a logical combination of the current direction information and the motor terminal voltage information.Type: GrantFiled: October 18, 2018Date of Patent: September 21, 2021Assignee: MITSUBA CorporationInventors: Yuichi Yanagita, Takuya Uchida

Patent number: 8927588Abstract: To develop an antibiotic having a novel mechanism of action, the present inventors have searched for a compound that has weak cytotoxicity, the physical property of high solubility in water, the effect of inhibiting both DNA gyrase GyrB and topoisomerase IV ParE subunits, and sufficient antibacterial activity. As a result, the present inventors have completed the present invention by finding that a compound of the present invention represented by the general formula (1), a pharmacologically acceptable salt thereof, and a prodrug thereof have desirable properties. The present invention provides a pharmaceutical composition (particularly, a preventive or therapeutic composition for infectious disease) comprising a compound represented by the formula (1), a pharmacologically acceptable salt thereof, or a prodrug thereof as an active ingredient.Type: GrantFiled: September 13, 2013Date of Patent: January 6, 2015Assignee: Daiichi Sankyo Company, LimitedInventors: Tsuyoshi Soneda, Hiroshi Takeshita, Yoshiko Kagoshima, Yuko Yamamoto, Takafumi Hosokawa, Toshiyuki Konosu, Nobuhisa Masuda, Takuya Uchida, Issei Achiwa, Junichi Kuroyanagi, Tetsunori Fujisawa, Aki Yokomizo, Tetsuji Noguchi
