Patent number: 11058982Abstract: A an electric machine tool having a body to which a work tool is attached, a motor, and a battery. The body has a motor receiving chamber, a battery receiving chamber opening through an outer surface of the body, and a communication path through which the battery receiving chamber is in communication with the motor receiving chamber. A first air inlet opening is formed between the inner edge of an opening of the battery receiving chamber and the outer periphery of the battery disposed in the battery receiving chamber. Further, an inflow port of the communication path opens to an inner side surface of the battery receiving chamber and an air filter is fitted over the inflow port.Type: GrantFiled: February 26, 2019Date of Patent: July 13, 2021Assignee: YAMABIKO CORPORATIONInventors: Hirokazu Miura, Noriyuki Takeuchi, Koji Hirakawa, Atsushi Nishimura, Kunihiko Haramoto, Tomohiro Nakashima

Patent number: 11000885Abstract: A contaminated soil purification system for decomposing a contaminant in contaminated soil E. The contaminated soil purification system includes: injecting, into contaminated soil through a water injection well, an injection liquid containing a purification agent to decompose a contaminant or an activator to stimulate biological decomposition by the purification agent; a process of measuring a concentration of the purification agent or the activator in groundwater in an observation well or in a pumping well, the observation well or the pumping well being provided at a location spaced apart from the water injection well; and a process of, based on the concentration that has been measured, automatically controlling an addition amount of the purification agent or the activator to the injection liquid or automatically controlling a pumping amount of water from the pumping well.Type: GrantFiled: August 29, 2017Date of Patent: May 11, 2021Assignee: Takenaka CorporationInventors: Tomohiro Nakashima, Takaaki Shimizu, Haruka Kiyotomo, Yamato Shimizu, Nobuyasu Okuda, Yasuhide Furukawa, Yuji Yamazaki, Kazuhiro Mukai, Kaoru Inaba
