Publication number: 20240106322Abstract: In a power conversion system, a control circuit has, as its operation modes: a first control mode in which control circuit controls a DC-DC converter at a first drive frequency; a second control mode in which control circuit controls DC-DC converter at a second drive frequency higher than first drive frequency; and a third control mode in which control circuit controls DC-DC converter at a third drive frequency higher than first drive frequency. Control circuit is configured to change operation mode from first control mode into second control mode when detector circuit detects a predetermined change in output voltage while control circuit is operating in first control mode. Control circuit controls DC-DC converter in third control mode in a process of changing, in response to detection of predetermined change, operation mode from first control mode into second control mode before starting to control DC-DC converter in second control mode.Type: ApplicationFiled: January 22, 2022Publication date: March 28, 2024Inventors: Hirokazu NAKAMURA, Kohei TSUKAMOTO, Kenichi ASANUMA, Ryoji MATSUI

Patent number: 9598098Abstract: A steering wheel provided with a vibration device. The vibration device includes a vibration motor with a weight attached to a rotational axis protruding out of a motor body, a mounting bracket which mounts the motor on the steering wheel body, a circuit substrate which includes a connector for feeding the vibration motor with electricity and a terminal which is plugged in a terminal hole of a mounting base of the motor body such that the circuit substrate is connected to the motor body, and a clip which is assembled with the motor body and mounted on the mounting bracket together with the motor body. The clip includes a pressing section which presses the circuit substrate against the motor body and a retaining element that is engaged with and holds the mounting bracket so as to help the pressing section to keep pressing the circuit substrate toward the motor body.Type: GrantFiled: March 12, 2015Date of Patent: March 21, 2017Assignee: TOYODA GOSEI CO., LTD.Inventors: Koji Sakurai, Norio Umemura, Naoki Tsukamoto, Hisatoshi Ota, Kenji Onda, Kenichi Matsui

Patent number: 9583674Abstract: A method for producing a semiconductor light emitting element includes a wafer preparation step, a first irradiation step, a second irradiation step, and a wafer division step. The wafer includes a semiconductor structure on a first main surface of a substrate. In the first irradiation step, a first light-condensing position in the thickness direction of the substrate is irradiated with a first laser beam from a second main surface of the substrate to form an altered area. The second main surface is opposite to the first main surface. In the second irradiation step, a second light-condensing position is irradiated with a second laser beam. The second light-condensing position is located at a position in the altered area different from the first light-condensing position. In the wafer division step, the wafer is divided into individual light emitting elements.Type: GrantFiled: June 18, 2015Date of Patent: February 28, 2017Assignee: NICHIA CORPORATIONInventors: Hitoshi Minakuchi, Kenichi Matsui
