Patent number: 10444293Abstract: A battery voltage measurement circuit measures voltages at a plurality of rechargeable batteries. The rechargeable batteries are connected to a flying capacitor via input-side semiconductor switches. The capacitor is connected to inverting input terminals of first and second differential amplification circuits. Output terminals of the differential amplification circuits are directly or indirectly connected to a calculation unit that calculates voltages at the rechargeable batteries. The output terminal and the inverting input terminal of each differential amplification circuit are connected via a corresponding sub-capacitor. Each differential amplification circuit includes a non-inverting input terminal connected to a reference potential. The negative electrode of the rechargeable battery is connected to the reference potential via a leakage detection circuit.Type: GrantFiled: March 11, 2015Date of Patent: October 15, 2019Assignee: PRIMEARTH EV ENERGY CO., LTD.Inventors: Yusuke Kozuka, Mitsuhiro Kamo

Patent number: 9671469Abstract: A voltage detection circuit for a secondary battery. A secondary battery is composed of a plurality of battery blocks (B1) to (B3), and is connected to a flying capacitor (C1) via input side sampling switches (SW1) to (SW3). The flying capacitor (C1) is connected to a differential amplifier circuit (10) via output side sampling switches (SWa) and (SWb). A feedback capacitor (C2) is connected to an inverting input terminal of the differential amplifier circuit (10) to form an integrator circuit, which reduces the capacitance of the flying capacitor (C1).Type: GrantFiled: September 22, 2011Date of Patent: June 6, 2017Assignee: PRIMEARTH EV ENERGY CO., LTD.Inventors: Yuusuke Koduka, Mitsuhiro Kamo, Tsuyoshi Miyahara

Patent number: 9056629Abstract: A personal vehicle control device includes an operation portion for inputting an original command value related to a turning angle, an axis angle sensor for detecting physical quantities related to a roll angle and a turning angle, wheel sensors, and a control portion. The control portion executes at least one of a first calculation law in which an actual command value related to a rotation angular velocity for driving wheels is obtained on the basis of a roll angle and the original command value, and a second calculation law in which the actual command value is obtained on the basis of an integrated value of a difference and/or an integrated value which is an integral of a ratio between the command value related to the turning angle and the physical quantity related to the turning angle with respect to time and on the basis of the original command value.Type: GrantFiled: March 15, 2013Date of Patent: June 16, 2015Assignee: AISIN SEIKI KABUSHIKI KAISHAInventors: Mitsuhiro Kamo, Yu Banno, Osamu Matsumoto

Patent number: 6206450Abstract: There is provided an automotive convertible top attaching construction in which a roof is opened, and an open portion is covered with a top cloth, characterized in that the front end portion of the top cloth 12 is mounted to a top fixing panel 15, a frame 16 supporting the top fixing panel 15 is pivotally mounted on both sides of the open portion rotatably in the longitudinal direction of vehicle body, and the top fixing panel 15 is mounted to the frame 16 rotatably with respect to the axis in the vehicle width direction. Therefore, the flattering of the top cloth 12 can be prevented when the top cloth 12 is open. Thereby, the entrance of wind into the folded top cloth can be prevented when a sun roof portion is open, and the appearance can be improved.Type: GrantFiled: April 15, 1998Date of Patent: March 27, 2001Assignee: Suzuki Motor CorporationInventors: Kuniteru Ide, Mitsuhiro Kamo
