Publication number: 20230324962Abstract: An angle adjustment device capable of being kept at a desired angle is provided. The angle adjustment device can fix and keep the relative positions of the first base component and the second base component, and a support with a combination of the angle adjustment device and components such as a flat plate can keep the entire body in a shape opened on a plane, a folded shape, a shape kept at a desired angle, or the like. In addition, the angle adjustment device can make a bending movement in one direction, which prevents bending in a reverse direction. Therefore, it is possible to prevent an accidental bending movement of an apparatus including the angle adjustment device to prevent breakage or the like of the apparatus.Type: ApplicationFiled: December 24, 2020Publication date: October 12, 2023Inventors: Taiki NONAKA, Kazuhiko FUJITA, Akio ENDO, Yuta ISHIKAWA

Publication number: 20230004207Abstract: The power consumption of a control device or a data processing system is reduced. Safety is enhanced. An electronic device is operated in a simple way. A control device includes an arithmetic circuit, an input unit, and a power management unit. The input unit includes a sensor element. The power management unit has a function of controlling supply and shutdown of power to the arithmetic circuit. The power management unit has a function of supplying power to the arithmetic circuit in response to a detection signal output from the sensor element. The sensor element includes one or more selected from an acceleration sensor, an angular velocity sensor, and a magnetic sensor. The arithmetic circuit includes a register. The register includes a first circuit and a second circuit.Type: ApplicationFiled: November 25, 2020Publication date: January 5, 2023Inventors: Haruki KATAGIRI, Kyoichi MUKAO, Taiki NONAKA, Kazuhiko FUJITA, Yuta ISHIKAWA

Patent number: 11283287Abstract: In a vehicle power-supply system, a backup power-supply device includes a low-voltage DC/DC converter, a backup battery, and switching mechanisms. A bidirectional switch unit is provided between a high-voltage DC/DC converter and a connecting point on a connecting wire and passes or interrupts a current flowing between the high-voltage DC/DC converter and the connecting point. A bidirectional switch unit is provided between the connecting point and a connecting point on a connecting wire and passes or interrupts a current flowing between the connecting point and the connecting point. A unidirectional switch unit is provided between the connecting point and the low-voltage DC/DC converter on the connecting wire and passes or interrupts a current flowing from the connecting point to the low-voltage DC/DC converter.Type: GrantFiled: January 21, 2021Date of Patent: March 22, 2022Assignee: YAZAKI CORPORATIONInventors: Takaaki Izawa, Masataka Komiyama, Yuta Ishikawa

Patent number: 11133702Abstract: In a vehicle power supply system, when a main power supply device is normal, a backup controller turns on a switch circuit and turns off a switch circuit to supply power from the main power supply device to a load unit LD1 and a load unit, and can travel a vehicle in a normal mode which is in a normal driving state. On the other hand, when the main power supply device is abnormal, the backup controller supplies power from the backup battery to the load unit and does not supply power from the backup battery to the load unit by turning on the switch circuit and turning off the switch circuit, and can travel the vehicle in the limit mode in which the functions are more limited than in the normal mode.Type: GrantFiled: July 24, 2020Date of Patent: September 28, 2021Assignee: YAZAKI CORPORATIONInventors: Takaaki Izawa, Masataka Komiyama, Yuta Ishikawa
