Patent number: 10309876Abstract: An airborne substance sensing device is capable of blocking fluorescence that is not from an airborne substance and detecting faint fluorescence of an airborne substance with a high degree of accuracy through the use of a cartridge having an introduction plate in which micropores are formed through which a gas including an airborne substance can pass. A transparent collection plate opposes the introduction plate, and the airborne substance can be made to collide on the plate and be collected through the collision of the gas having passed through the micropores. In a main body, the introduction and collection plates are disposed in parallel, and a flow path for guiding the gas including the airborne substance to the micropores is formed. An opaque mask covers the collection plate and is provided with an opening window through which light can pass at a position corresponding to a collection area.Type: GrantFiled: October 3, 2013Date of Patent: June 4, 2019Assignee: Hitachi, Ltd.Inventors: Kei Takenaka, Shigenori Togashi

Patent number: 9433883Abstract: The present invention provides an impaction-based microorganism collecting device in which microorganisms are captured by the capture surface of a collection plate. The microorganism collecting device is designed to reduce the influence of the lateral wind flowing over the perforated plate having multiple nozzles and also prevent warpage of the perforated plate. Multiple air vents are formed around the circumference of the capture surface and through the capture surface so that air that has flowed through the nozzles of the perforated plate onto the capture surface can be discharged. This allows the air to flow in multiple directions over the capture surface, thereby reducing the speed of the air and increasing the microorganism capture rate.Type: GrantFiled: February 22, 2011Date of Patent: September 6, 2016Assignee: Hitachi, Ltd.Inventors: Kei Takenaka, Yasuhiko Sasaki, Shigenori Togashi
