Patent number: 10022029Abstract: An electric vacuum cleaner, including a cleaning unit includes a body case including a dust container opening, and a primary dust container including: a container body detachably provided to the body case accumulating dust collected by the cleaning unit; a connecting part exposed from or facing the dust container opening, when attached to the body case; a disposal port provided in the connecting part, for discharging dust from inside the container body; and a disposal lid opening and closing the disposal port. The station includes a dust transfer pipe contacting the connecting part of the primary dust container and connected to the disposal port, and a secondary dust container in which dust discharged from the primary dust container through the dust transfer pipe is accumulated.Type: GrantFiled: July 2, 2015Date of Patent: July 17, 2018Assignee: TOSHIBA LIFESTYLE PRODUCTS & SERVICES CORPORATIONInventors: Yukio Machida, Masatoshi Tanaka, Atsushi Morishita, Yuji Ohtsuka, Hiromitsu Ichikawa, Hiromitsu Murata

Patent number: 10010834Abstract: A membrane separation device includes a separation membrane immersed in water to be treated and an air diffusion device positioned below the separation membrane, and provides treated water that has permeated through the separation membrane while diffusing air from the air diffusion device towards the separation membrane. A target value setting step sets a target value of an amount of diffusion air diffused from the air diffusion device based on a transmembrane pressure difference, and the air diffusion device is controlled such that the amount of the diffusion air becomes the target value. In the target value setting step, an absolute value of a change or a rate of change in the target value for increasing the amount of the air diffusion is set greater than an absolute value of a change or a rate of change in the target value for decreasing the amount of the air diffusion.Type: GrantFiled: September 25, 2014Date of Patent: July 3, 2018Assignee: Kubota CorporationInventors: Yasuyuki Yoshida, Yuji Ohtsuka

Patent number: 9907447Abstract: An electric vacuum cleaner in which a dust container inside an autonomous robotic vacuum cleaning unit can be fluidically connected to a station using propulsive force of the cleaning unit moving to a dust discharge position. The cleaning unit includes a body case, and a primary dust container including: a container body accumulating dust collected by the cleaning unit; a disposal port discharging dust from inside the container body; and a disposal lid opening and closing the disposal port. The station includes a dust transfer pipe connected to the disposal port of the primary dust container; a lever hooked by the disposal lid while the cleaning unit is homing, opening the disposal lid and connecting the disposal port and the dust transfer pipe; and a secondary dust container in which dust discharged from the primary dust container through the dust transfer pipe is accumulated.Type: GrantFiled: July 2, 2015Date of Patent: March 6, 2018Assignee: TOSHIBA LIFESTYLE PRODUCTS & SERVICES CORPORATIONInventors: Masatoshi Tanaka, Yukio Machida, Atsushi Morishita, Yuji Ohtsuka, Hiromitsu Ichikawa, Hiromitsu Murata

Publication number: 20160016833Abstract: An organic wastewater treatment apparatus includes (a) a treatment tank, (b) a plurality of membrane separation devices immersed in the treatment tank, where each membrane separation device is provided with a diffuser device and a permeated liquid extracting device, (c) a plurality of sludge characteristics measuring devices dispersedly disposed in the treatment tank, and (d) a controller. An operating method divides the treatment tank into a plurality of regions, and sets at least one of an amount of air diffusion and a flow rate of permeated liquid for each membrane separation device based on a measured value of the sludge characteristics measuring device disposed in the corresponding region. The controller sets at least one of the amount of air diffusion and the flow rate of permeated liquid based on the measured value of the sludge characteristics measuring device in a vicinity of which the membrane separation device is disposed.Type: ApplicationFiled: September 25, 2015Publication date: January 21, 2016Inventors: Yasunobu OKAJIMA, Yukako MORITA, Yuji OHTSUKA
