Publication number: 20230022384Abstract: A multiplying image sensor includes a semiconductor layer having a first surface and a second surface and a wiring layer provided on the second surface. The semiconductor layer includes a plurality of pixels arranged along the first surface. Each of the plurality of pixels includes a first semiconductor region, a second semiconductor region formed on the second surface side with respect to at least a part of the first semiconductor region and divided for each of the plurality of pixels, and a well region formed in the second semiconductor region so as to be separated from the first semiconductor region and forming a part of a pixel circuit. At least a part of the first semiconductor region and at least a part of the second semiconductor region form an avalanche multiplication region.Type: ApplicationFiled: November 11, 2020Publication date: January 26, 2023Applicant: HAMAMATSU PHOTONICS K.K.Inventors: Mitsuhito MASE, Jun HIRAMITSU, Hiroaki ISHII, Yuma TANAKA, Toshinori ITO

Publication number: 20230026004Abstract: A ranging image sensor includes a semiconductor layer and an electrode layer. The semiconductor layer and the electrode layer form a plurality of pixels. Each of the plurality of pixels includes an avalanche multiplication region, a charge distribution region, a first charge transfer region, and a second charge transfer region in the semiconductor layer. Each of the plurality of pixels includes a photogate electrode, a first transfer gate electrode, and a second transfer gate electrode in the electrode layer. The avalanche multiplication region is continuous over the plurality of pixels or reaches a trench formed in the semiconductor layer so as to separate the plurality of pixels from each other.Type: ApplicationFiled: December 7, 2020Publication date: January 26, 2023Applicant: HAMAMATSU PHOTONICS K.K.Inventors: Mitsuhito MASE, Jun HIRAMITSU, Akihiro SHIMADA, Hiroaki ISHII, Toshinori ITO, Yuma TANAKA

Patent number: 9089550Abstract: An object of the present invention is to provide a pancreatic islet transplantation technique that enables increase of graft survival rate of pancreatic islets after pancreatic islet transplantation, to maintain survival of pancreatic islets, and to reduce the number of transplanted pancreatic islets required for normalizing blood glucose level. When performing pancreatic islet transplantation, by transplanting pancreatic islets and adipose tissue-derived stem cells together, it is possible to significantly improve graft survival rate of transplanted pancreatic islets, and reduce by half the number of transplanted pancreatic islets required for normalizing blood glucose level.Type: GrantFiled: August 5, 2011Date of Patent: July 28, 2015Assignee: OSAKA UNIVERSITYInventors: Masahiro Tanemura, Yoshiaki Omura, Hiroaki Nagano, Masaki Mori, Yuichiro Doki, Toshinori Ito
