Patent number: 11971675Abstract: An image forming apparatus includes image bearers, motors, a reference position detector, and processing circuitry. The circuitry senses a density of a toner image on each bearer; forms an image pattern and senses, based on a detection result of the detector and a sensing result of the density, density unevenness in a rotation cycle and a phase of the density unevenness with respect to a rotational position reference of each bearer; calculates a target phase based on the phase sensed; calculates a relative phase difference based on a rotational position and the target phase of each bearer; selects, as a reference image bearer, an image bearer having a minimum phase correction value, based on a calculation result of the difference; and controls the rotational position of each of the other image bearers with respect to the reference image bearer to the phase correction value, with the motors being driven.Type: GrantFiled: November 29, 2022Date of Patent: April 30, 2024Assignee: Ricoh Company, Ltd.Inventors: Masashi Kasamai, Koji Kiryu, Masahiro Ashikawa, Jumpei Yamaguchi, Kanji Ubukata, Nagisa Nakamura

Patent number: 8297960Abstract: To provide a reliable solid-liquid separating method and apparatus for a slurry, even though the solid component of the slurry is finely divided particles and/or of a shape difficult to entangle, without exudation through gaps in processed portions and, also, with no need to exercise a maintenance work such as replacement of filters, a solid-liquid separating apparatus includes a mold having a cylindrical inner peripheral surface, a gate for opening and closing a second open end of the mold, and a pressing rod slidable into the mold to compress the slurry. Sheet-like fibrous filters are placed on a leading end face of the pressing rod and an inner surface of the gate to seal gaps between the mold and the pressing rod and between the gate and mold. With the filters so placed, the slurry within the mold unit is compressed to provide a solidified product, thereby accomplishing solid-liquid separation.Type: GrantFiled: September 13, 2011Date of Patent: October 30, 2012Assignee: NTN CorporationInventor: Kanji Nakamura

Patent number: 6874411Abstract: A method of and an apparatus for compressing the grinding sludge, which is effective to compress the grinding sludge to provide an intended rigid briquette even though the grinding sludge contains ground chips of hardened iron and/or steel materials and an oil-based coolant and also to facilitate reuse of the briquette (B1) as material for production of steel. The grinding sludge containing the oil-based coolant and hardened component parts such as steel component parts that are used in bearings is compressed. To this end, the grinding sludge produced from a grinding line (1) is filtered by a filtering unit (4) to provide a concentrated sludge which is subsequently compressed by squeezing by a briquetting machine (5) to provide the briquette (B1). The briquette B1 so obtained can be reused as steel material. The coolant separated from the grinding sludge during filtering and squeezing is returned to the grinding line (1) through recovery passages (7, 8).Type: GrantFiled: April 20, 2001Date of Patent: April 5, 2005Assignee: NTN CorporationInventors: Kanji Nakamura, Yasuyuki Yamada, Tetsuo Suzuki, Katsuhiro Suzuki
