Patent number: 11178137Abstract: A data communication system has an IoT device, an information processing device capable of performing communication with the IoT device, and a server capable of performing communication with the IoT device and the information processing device. When a coupling request from the IoT device is received, the information processing device requests the server for a tentative common key which is temporarily valid. When a request for a tentative common key from the information processing device is received, the server generates a tentative common key and transmits the tentative common key to the information processing device. The information processing device transmits the received tentative common key to the IoT device, and the IoT device and the server perform authentication by using the tentative common key.Type: GrantFiled: May 10, 2019Date of Patent: November 16, 2021Assignee: RENESAS ELECTRONICS CORPORATIONInventors: Takahide Todoroki, Koichi Sato, Kazuhiko Noto

Patent number: 9758393Abstract: Provided is a fresh water generation system which filters biotreated water produced by microbiologically treating waste water via a primary semi-permeable membrane (8), and then mixes concentrated water rejected by the filtration with seawater, thereby to filter the mixed water via a secondary semi-permeable membrane (14). This system enables frequencies of chemical cleaning and replacement of the secondary semi-permeable membrane to be reduced. The fresh water generation system comprises: a primary semi-permeable membrane apparatus (9) which separates microorganism treating waste water into permeated water and concentrated water; a secondary semi-permeable membrane apparatus (13) which filters mixed water prepared by mixing the concentrated water into seawater. In the fresh water generation system, the primary semi-permeable membrane (8) has an equal to or a higher microorganism adhesive property than the secondary semi-permeable membrane (14).Type: GrantFiled: September 24, 2012Date of Patent: September 12, 2017Assignees: HITACHI, LTD., TORAY INDUSTRIES, INC.Inventors: Kazuhiko Noto, Kotaro Kitamura, Yusuke Okawa, Hiroo Takabatake
