A workpiece for a fuel injection component is made of a steel having compositions, by mass %, of C: 0.08 to 0.16%, Si: 0.10 to 0.30%, Mn: 1.00 to 2.00%, S: 0.005 to 0.030%, Cu: 0.01 to 0.30%, Ni: 0.40 to 1.50%, Cr: 0.50 to 1.50%, Mo: 0.30 to 0.70%, V: 0.10 to 0.40%, s-Al: 0.001 to 0.100%, and Fe and unavoidable impurities as remaining components. After heating the workpiece to a temperature of 950&#xb0; C. or more and 1350&#xb0; C. or less, the workpiece is subjected to a hot forging, and thereafter cooled at an average cooling rate of 0.1&#xb0; C./sec. or more in a temperature range from 800&#xb0; C. to 500&#xb0; C., and at the average cooling rate of 0.02&#xb0; C./sec. or more and 10&#xb0; C./sec. or less in the subsequent temperature range from 500&#xb0; C. to 300&#xb0; C. to set an area ratio of a bainite structure after hot forging to 85% or more.

Method for manufacturing fuel injection component

There are provided a sheet feeding apparatus and an image forming system which can horizontally maintain a posture of a topmost envelope in stored envelopes, by a simple configuration. The sheet feeding apparatus includes: a stacking surface portiona sheet feeding rollera pressing surface portionand a curve forming portionA length of the stacking surface portionin a width direction is shorter than a length of each of envelopes P in a width direction. The pressing surface portionis pressed by the sheet feeding rollervia the envelopes P. The curve forming portionis arranged outside the sheet feeding rollerin a width direction, projects more upward in a vertical direction than the pressing surface portionand supports the plurality of stacked envelopes P with a predetermined size.

Sheet feeding apparatus and image forming system

A paper feed apparatus includes: a sheet tray on which sheets are stacked; a sheet attractor which is located above the sheet tray and attracts sheets one by one from the above; a leading edge fan which is located in a leading edge side of the sheets and blows separation air against leading edges of the sheets to separate an uppermost sheet of the sheets closest to the sheet attractor from lower sheets located below the uppermost sheet; a sheet conveyor which is located in a downstream side of the sheet attractor along a conveying direction of the sheets to convey the uppermost sheet which is attracted by the sheet attractor and separated from the lower sheets by the leading edge fan; and a lifting member which is detachably provided on the sheet tray to support a tail side of a back of the sheets.

Paper feed apparatus and paper feed unit

A paper feeding device of an image forming device includes a flotation air blowing unit and a separation air blowing unit. The flotation air blowing unit floats stacked uppermost paper through air blowing. The separation air blowing unit blows an end of other paper floated together with the floated uppermost paper to separate the other paper from the uppermost paper, the end being on the downstream side in the paper feeding direction. The flotation air blowing unit floats an end of the stacked uppermost paper, the end being on the downstream side in the paper feeding direction. The paper feeding device includes a resistance force applying mechanism which applies resistance force that gives a load against movement along the paper feeding direction to an end of stacked upper paper, the end being on the upstream side in the paper feeding direction.

A sheet supplying device, including a sheet stacking member which can stack various sized sheets, a side edge alignment member which moves perpendicular to a sheet supplying direction and aligns at least one of side edges of the stacked sheets placed on the sheet stacking member, and an auxiliary side edge alignment member which is provided on the side edge alignment member and ejects in a moving direction of the side edge alignment member and which aligns stacked sheets whose width is narrower than that of the stacked sheets which are to be aligned by the side edge alignment member.

Sheet supplying device and image forming system

Disclosed is a sheet transport device having: a registration roller to transport a sheet after correcting a skew of the sheet; a drive source to drive the registration roller; a frame body; and a rotation resisting body which is connected to the registration roller on one side and is connected to the frame body on the other side, to create a resisting force against a rotation of the registration roller in a sheet transport direction.

Sheet transport device

According to this invention, in a manual feed apparatus having an opening/closing tray which can be stored in an image forming apparatus main body by swing operation, and a feedout member which feeds a sheet stacked on the opening/closing tray, the opening/closing tray is swingably connected to a vertically movable support member which is restricted to be movable in a vertical direction, and the apparatus includes a vertically movable unit which moves the vertically movable support member in the vertical direction.

Manual feed apparatus

A color image forming apparatus is provided wherein toner images formed on a plurality of image carriers are primarily transferred onto an intermediate transfer object, and then, are secondarily transferred onto a recording sheet. The color image-forming apparatus includes an intermediate transfer member, a longitudinal direction of which is arranged in substantially a vertical direction, and onto which toner images formed on image carriers are sequentially transferred in such a manner that the toner images overlap relative to each other so as to form a color toner image on the intermediate transfer member. In addition, a transferring device is provided to transfer the color toner image formed on the intermediate transfer member onto a transfer sheet. The intermediate transfer member and the image carriers are integrated into a rack, and the rack is drawable in substantially a horizontal direction with respect to a mainframe of the color image-forming apparatus.

Color image forming apparatus

The present invention concerns a color image forming apparatus wherein toner images formed on a plurality of image carriers are primarily transferred onto an intermediate transfer object, and then, are secondarily transferred onto a recording sheet. The color image-forming apparatus includes a plurality of image carriers; a plurality of latent image forming devices to form electrostatic latent images on the image carriers; a plurality of developing devices to develop the electrostatic latent images with toner to form visible toner images on the image carriers; an intermediate transfer member, a longitudinal direction of which is arranged at substantially a vertical direction, and onto which the toner images formed on the image carriers are sequentially transferred in such a manner that the toner images overlap relative to each other so as to form a color toner image on the intermediate transfer member; and a transferring device to transfer the color toner image formed on the intermediate transfer member onto a transfer sheet. The intermediate transfer member and the image carriers are integrated into a rack, and the rack is drawable in substantially a horizontal direction in respect to a mainframe of the color image-forming apparatus.
