Publication number: 20120051795Abstract: Aspects described herein relate to a cap for a toner cartridge. In one example, the cap may be configured to close a toner supply opening of the toner cartridge. According to one or more aspects, the cap may include a sealing or covering portion configured to cover the toner supply opening and a shaft portion for rotatably supporting a to-be-detected rotary member. The to-be-detected rotary member 56 is rotatably supported around and fitted onto the shaft portion. Therefore, even if a toner supply opening of a cartridge is provided in a sidewall of the housing on a side where the to-be-detected rotary member is provided, e.g., a left sidewall, the toner supply opening and the to-be-detected rotary member can be provided in such a manner as to overlap each other.Type: ApplicationFiled: August 31, 2011Publication date: March 1, 2012Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventors: Motoaki Mushika, Tsutomu Suzuki, Yasuo Fukamachi, Fumikazu Sato, Hikaru Yoshizumi, Takahiro Nishimoto

Patent number: 8064661Abstract: In a container of a cell culture device, a light source and a camera are arranged on both sides of an incubator, and the camera or incubator can be moved in relation to each other. An image of cells in the incubator is captured with a given focus. The medium, image density, and noise component of images captured while varying the focus of the camera have substantially similar pixel values. Consequently, by subjecting the data on the images captured with such different focuses to differential processing, only the cell portion can be extracted without being influenced by the color variation of the medium, the variation of the amount of light, the difference in brightness between the central and peripheral areas of the image, and the noise.Type: GrantFiled: November 9, 2005Date of Patent: November 22, 2011Assignee: Kaneka CorporationInventors: Yoshihiro Komori, Tsutomu Suzuki

Publication number: 20110150527Abstract: A developer cartridge provided in an image-forming device has a developer side casing that includes a toner-accommodating chamber and a developing chamber; and a plate wall disposed in the developing chamber for partitioning a thickness-regulating blade from the toner-accommodating chamber. When a thickness-regulating blade scrapes excess charged toner off the developing roller, the plate wall prevents this charged toner from returning to the toner-accommodating chamber. A flexible wiper for cleaning toner detection windows is attached to an agitator for stirring toner in the toner-accommodating chamber via a fixing member. The fixing member includes a support plate and a gripping plate disposed opposite each other with a slit formed therebetween. The wiper is inserted into the slit and is fixed to the fixing member when a boss protruding from a restricting plate becomes inserted into a through-hole formed in the wiper.Type: ApplicationFiled: March 2, 2011Publication date: June 23, 2011Applicant: BROTHER KOGYO KABUSHIKI KAISHAInventors: Isao KISHI, Takeyuki Takagi, Tsutomu Suzuki

Patent number: 7818014Abstract: To reduce load on an access point even if a large number of wireless stations are located very close to the access point. An access point detects a communication load value (S1 and S2) and reports it to wireless stations (S3). The access point waits for a predetermined time after the transmission of the communication load value (5) and detects a communication load value again (S6 and S7). The access point determines whether the first communication load value is larger than a predetermined value K (S4) and whether the second communication load value is larger than K (S8). If the first and second communication load values are larger than K, the access point outputs a warning output command instructing the wireless stations to output a warning prompting their users to move away from their current locations (S9).Type: GrantFiled: March 29, 2006Date of Patent: October 19, 2010Assignee: Hitachi, Ltd.Inventors: Masaaki Takizawa, Tsutomu Suzuki
