Patent number: 11639314Abstract: A porous fired granulated body is formed by consolidating numerous alumina particles to each other while letting mainly interconnected pores remain in network form across an entire cross section of a granulated body particle. The pores have an inner diameter controlled by a droplet diameter of a pore forming agent and have numerous precipitated alumina crystals formed on inner surfaces thereof. Manufacture is performed by spraying the pore forming agent (emulsion) onto a raw material to form a coating layer of the pore forming agent on a surface of the raw material particle and controlling the inner diameter of the pores. A porous fired granulated body of alumina having a high specific surface area and having higher strength for the same specific surface area can thus be provided by a simple manufacturing method.Type: GrantFiled: February 17, 2020Date of Patent: May 2, 2023Assignee: Itochu Ceratech CorporationInventors: Akira Takahashi, Junya Shimosato, Takahiko Nakamura, Noriyuki Tamura

Patent number: 8864672Abstract: A blood rheology measurement device measures a blood rheology of blood flowing through an artery inside of a living body from outside of the living body. The blood rheology measurement device has a sensor that detects a flow rate of blood flowing through the artery and a pulsatile displacement that varies with an elapse of time. The pulsatile displacement corresponds to a displacement of the artery in a diameter direction thereof due to expansion and contraction of the artery resulting from a pulsatile motion of the heart. A calculating section calculates the blood rheology of blood flowing through the artery on the basis of the blood flow rate and the pulsatile displacement detected by the sensor.Type: GrantFiled: February 9, 2006Date of Patent: October 21, 2014Assignee: Seiko Instruments Inc.Inventors: Fumio Kimura, Takahiko Nakamura, Masataka Shinogi, Mizuaki Suzuki
