Patent number: 11988720Abstract: A semiconductor device that detects deterioration of a secondary battery is provided. The semiconductor device includes a power gauge, an anomalous current detection circuit, and a control circuit. The power gauge includes a current divider circuit and an integrator circuit. The anomalous current detection circuit includes a first memory, a second memory, and a first comparator. The integrator circuit can convert a detection current detected at the current divider circuit into a detection voltage by integrating the detection current. The anomalous current detection circuit is supplied with the detection voltage, a first signal at a first time, and a second signal at a second time. The first signal can make the detection voltage at the first time be stored in the first memory and the second signal can make the detection voltage at the second time be stored in the second memory.Type: GrantFiled: December 13, 2019Date of Patent: May 21, 2024Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Kei Takahashi, Takayuki Ikeda, Ryota Tajima, Mayumi Mikami, Yohei Momma, Munehiro Kozuma, Takanori Matsuzaki

Patent number: 11858327Abstract: A vehicle drive device includes a rotary electric machine disposed on a first axis, an output member disposed on a second axis parallel to the first axis, an inverter device, a terminal block for electrically connecting a rotary electric machine-side bus bar and an inverter-side bus bar, and a case. The case includes a first housing chamber for housing the rotary electric machine MG, a second housing chamber for housing the inverter device, and a partition wall for separating the first housing chamber and the second housing chamber. A terminal block is disposed such that an arrangement area of the terminal block in an axial direction overlaps the rotary electric machine, and disposed so as to penetrate the partition wall in a radial direction of the output member.Type: GrantFiled: February 24, 2021Date of Patent: January 2, 2024Assignee: AISIN CORPORATIONInventors: Masahiro Nagaya, Nozomu Takahashi, Ryohei Inoue, Takeshi Torii, Daisuke Yamaoka, Taketoki Maruyama, Toshiya Sugiyama, Munehiro Takahashi

Patent number: 9134441Abstract: A cross-sectional area calculation section calculates a cross-sectional area of a subject as physical quantity with respect to a size of the subject, and an NEC calculation section calculates a noise equivalent count NEC as physical quantity for evaluating an image. The C-NEC calculation section calculates a noise equivalent count per unit area C-NEC as physical quantity for evaluating an image as per size of the subject in accordance with the cross-sectional area of the subject calculated in the cross-sectional area calculation section and the noise equivalent count NEC calculated in the NEC calculation section. Accordingly, the noise equivalent count per unit area C-NEC is calculated as noted above, whereby an index may be determined that is independent of the cross-sectional area of the subject in evaluating the image.Type: GrantFiled: March 26, 2008Date of Patent: September 15, 2015Assignees: SHIMADZU CORPORATION, FOUNDATION FOR BIOMEDICAL RESEARCH AND INNOVATIONInventors: Tetsuro Mizuta, Keishi Kitamura, Yuichi Inaoka, Munehiro Takahashi, Michio Senda, Keiichi Matsumoto, Keiji Shimizu

Patent number: 5705819Abstract: An emission CT apparatus for detecting, in positions around an examinee, radiation from radioactive nuclides introduced into the examinee and having accumulated in a site of concern, in order to acquire density distribution images (sectional images) of the nuclides in sections of the site of concern. The apparatus comprises a gamma camera for detecting the radiation, a rotary device for revolving the gamma camera stepwise round the examinee, an image memory for collecting image data from the gamma camera for respective time frames defined by dividing a period of time for which the gamma camera stands still at each angular position, a computing unit for determining a center of gravity of the image data in each time frame, an adder for adding image data, with the center of gravity brought into agreement, in each time frame, thereby to obtain image data in a direction of each angular position (view), and an image reconstruct unit for reconstructing an image based on the image data of each view corrected.Type: GrantFiled: January 30, 1995Date of Patent: January 6, 1998Assignee: Shimadzu CorporationInventors: Munehiro Takahashi, Tsunekazu Matsuyama
