Patent number: 11510538Abstract: In a vacuum cleaner electric blower is driven by power supplied by a secondary battery. A dust-collector is configured to catch and collect dust and dirt sucked by driving the electric blower. A detector is configured to detect a remaining amount of the secondary battery. A controller is configured to control suction force of the electric blower. In the case cleaning is finished when the remaining amount of the secondary battery detected by the detector is equal to or less than a predetermined value, the controller sets the parameter to reduce the suction force of the electric blower for the next cleaning. In the case cleaning is finished when the remaining amount of the secondary battery detected by the detector is not equal to or less than the predetermined value, the controller sets the parameter to increase the suction force of the electric blower for the next cleaning.Type: GrantFiled: February 15, 2019Date of Patent: November 29, 2022Assignee: TOSHIBA LIFESTYLE PRODUCTS & SERVICES CORPORATIONInventor: Yutaka Kashihara

Patent number: 11096533Abstract: In a dust station, a suction part is connected selectively to one of a first suction port and a second suction port. In a state where the first suction port is connected to the suction part, a dust-collecting control unit drives the suction part and also automatically stops the suction part after elapsing of a first specified period of time. In a state where the second suction port is connected to the suction part, the dust-collecting control unit drives the suction part, and enables stopping the suction part through specified operation and also stops the suction part automatically when the suction part is not stopped even after elapsing of a second specified period of time or longer in a state where the suction part is driven, the second specified period of time being different from the first specified period of time.Type: GrantFiled: November 24, 2016Date of Patent: August 24, 2021Assignee: TOSHIBA LIFESTYLE PRODUCTS & SERVICES CORPORATIONInventor: Yutaka Kashihara

Patent number: 8391113Abstract: An optical disc has a read-only system lead-in area and a recordable data area. Disc boundary information representing a boundary in a radial direction of an area on which capability of recording at a predetermined recording speed is guaranteed is recorded on the system lead-in area while being related to each tuple speed. An optical disc device, upon user's instruction of tuple-speed recording, compares the boundary information related to the instructed tuple speed with a present recording position, performs recording at the instructed tuple speed if the present recording position is on the outside of the boundary, and performs recording at a tuple speed lower than the instructed tuple speed if the present recording position is on the inside of the boundary.Type: GrantFiled: February 13, 2009Date of Patent: March 5, 2013Assignees: Sanyo Electric Co., Ltd., Toshiba Corporation, NEC CorporationInventors: Morio Nakatani, Masato Fuma, Kazuo Watabe, Yutaka Kashihara, Akihito Ogawa, Yutaka Yamanaka, Tatsunori Ide, Shuichi Ohkubo

Publication number: 20100031914Abstract: The tubular die of a centrifugal casting device of GNo.30 or above is employed suitably and powder is introduced while rotating, and an outer tubular body composed of that powder is provided. Subsequently, molten is introduced to the inner circumferential wall side of the outer tubular body while sustaining rotation of the tubular die thus forming an inner tubular body. The outer tubular body functions as a cooling metal (chiller) when the molten is cooled and solidified. In place of the outer tubular body composed of the powder, molten may be used for forming an outer tubular body or an outer tubular molding molded previously into tubular shape may be employed.Type: ApplicationFiled: March 10, 2008Publication date: February 11, 2010Applicant: HONDA MOTOR CO., LTDInventors: Tomonori Fukumoto, Yukio Iijima, Takaharu Echigo, Kazuaki Yamagami, Haruki Kodama, Yuji Imamaru, Yutaka Kashihara
