Patent number: 11948958Abstract: The solid-state imaging element includes a photoelectric converter, a first separator, and a second separator. The photoelectric converter is configured to perform photoelectric conversion of incident light. The first separator configured to separate the photoelectric converter is formed in a first trench formed from a first surface side. The second separator configured to separate the photoelectric converter is formed in a second trench formed from a second surface side facing a first surface. The present technology is applicable to an individual imaging element mounted on, e.g., a camera and configured to acquire an image of an object.Type: GrantFiled: June 9, 2022Date of Patent: April 2, 2024Assignee: SONY GROUP CORPORATIONInventors: Hideyuki Honda, Tetsuya Uchida, Toshifumi Wakano, Yusuke Tanaka, Yoshiharu Kudoh, Hirotoshi Nomura, Tomoyuki Hirano, Shinichi Yoshida, Yoichi Ueda, Kosuke Nakanishi

Patent number: 6545449Abstract: A method for controlling charge preventing an operation of a valve during charging and suppressing the false detection of the upper limit charging voltage due to the memory effect at the charge side in a secondary battery mounted on an automated guided vehicle is presented. The method includes charging the secondary battery at a charging current value of not less than 0.5 C and not more than 4.0 C; detecting current that flows in the secondary battery and calculating the remaining capacity by accumulating at least the detected current; and completing the charge to the secondary battery when the calculated remaining capacity is not less than the threshold value that is pre-set to not less than 60% and not more than 95%.Type: GrantFiled: April 9, 2002Date of Patent: April 8, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Toshifumi Ueda, Nobuyasu Morishita
