摘要： The developing device includes a casing, a developing roller, a thickness regulating blade, and a seal member. The developing roller has an outer peripheral surface carrying developer. The thickness regulating blade is configured to regulate a thickness of the developer carried on the outer peripheral surface and has an opposed surface confronting the casing. The thickness regulating blade further has one end part supported on the casing and another end part provided with a press member in sliding contact with the outer peripheral surface. The press member is located on the opposed surface and protrudes toward the developing roller. The press member is formed with a receiving portion depressed inward at its widthwise ends in an axial direction of the developing roller. The seal member is disposed between the thickness regulating blade and the casing and contacting at least a part of the receiving portion.

摘要： A developing device includes a casing having an opening extending in a first direction, a developing roller, a thickness-regulation member, an engagement portion and a sealing member. The thickness-regulation member includes a thin-plate member and a regulating portion. The thin-plate member is fixed to the casing and has a lateral end extending in a second direction. The regulating portion is fixed on the thin-plate member and has an end face extending in a direction. The engagement portion is fixed on the thin-plate member and positioned closer to the lateral end than the end face to the lateral end to provide a groove between the engagement portion and the end face. The sealing member is fitted in the groove and has a length in the first direction longer than a length of the groove prior to assembly of the sealing member into the groove.

摘要： A developing device includes: a casing; a developing roller mounted on the casing, and having a rotational axis extending in an axis direction and a peripheral surface on which a developer is carried, the developing roller being configured to rotate in a rotational direction about the rotational axis; and a seal provided between the casing and the developing roller to prevent the developer from leaking between peripheral surface and the casing. The seal includes: a film member opposed to the peripheral surface of the peripheral surface of the developing roller; and an elastic member provided between the film member and the casing to press the film member against the peripheral surface of developing member. The casing includes a restricting wall provided downstream of the seal member in the rotational direction to restrict the seal from moving in the rotational direction.

摘要： There is provided a sintered bearing having high rotational accuracy and low rotational fluctuation. This bearing includes a bearing surface (4a), and is made of a sintered compact (4″) produced by molding and sintering a raw material powder (10) containing a partially diffusion-alloyed powder (11) in which a copper powder (13) is partially diffused on a surface of an iron powder (12), a tin powder (14) as a low-melting-point metal powder, and a graphite powder as a solid lubricant powder. The sintered bearing has a radial crushing strength greater than or equal to 300 MPa.

摘要： When a cover 18 closes an opening end surface 11d of a boss 11, an annular piece 18a moves close to an annular groove 20 to form a labyrinth structure, and thus a flow path for turbocharged air becomes narrower to produce air resistance, which causes the cover 18 to be hardly closed. Thus, chattering is prevented from occurring, and a relief valve 10 can be prevented from being damaged.

摘要翻译： 当盖18关闭凸台11的开口端面11d时，环形件18a靠近环形槽20移动以形成迷宫式结构，因此涡轮增压空气的流路变窄，产生空气阻力， 盖18几乎不封闭。 因此，防止发生抖动，并且可以防止泄压阀10被损坏。

摘要： Input information of a multidimensional array is divided into a plurality of divided areas, accumulated information is generated by calculating accumulated values at respective element positions of the input information from a corresponding reference location for each of the plurality of divided areas, and the generated accumulated information is held in a memory for each divided area. Calculation using the accumulated information is executed for a predetermined processing range. The input information is divided into the plurality of divided areas so that two neighboring divided areas have an overlapping area, and the overlapping area has a size at least in which the whole processing range fits.
