摘要:
A steel having good wear resistance which contains 0.55-1.10% of C, up to 2.0% of Si, up to 2.0% of Mn, 12.0-25.0% of Cr and particularly suitable as a material for piston rings or rocker arms. Further addition of 0.05-1.10% of Al to the above steel gives a steel improved in properties for spheroidization of carbides and uniformization of carbide particle size, leading to further enhancement of wear resistance. If required 0.20-2.0% of Ni may be added to the steels, whereby corrosion resistance, toughness and hardenability are improved. An addition of at least one of 0.2-3.0% of Mo, 0.1-1.5% of V and 0.05-0.70% of Nb to the steels improves high-temperature strength and surface hardness. The steel is surface treated by gas nitriding of the like in a surface area for sliding contact with an opponent member.

An image forming apparatus includes a latent image bearer, a toner image forming unit, and a transfer device. The toner image forming unit includes a charger, a latent image forming device, and a developing device, and is configured to form a test latent image pattern on a surface of the latent image bearer, and to develop the test latent image pattern into a test toner pattern. The test latent image pattern includes a plurality of test latent image parts partly offset from one another in a main scanning direction. The image forming apparatus also includes a developing current detector and a processor to detect uneven image density in the main scanning direction using the test latent image pattern, based on the developing current detected by the developing current detector, to adjust the uneven image density in the main scanning direction.

A sintering composition and calcined object which are precursors for a sintered zirconia. The burned surface of the sintered zirconia gives an X-ray diffraction pattern in which the ratio of the height of the peak present around the location where a [200] peak assigned to the cubic system is to appear to the height of the peak present around the location where a [200] peak assigned to the tetragonal system is to appear is 0.4 or more, and a region located at a depth of 100 μm or more from the burned surface gives an X-ray diffraction pattern in which the ratio of the height of the peak present around the location where a [200] peak assigned to the cubic system is to appear to the height of the peak present around the location where a [200] peak assigned to the tetragonal system is to appear is 0.3 or less.
摘要:
An image forming apparatus includes an image carrier; a developing device; a transfer device; and a fixing device. An electrostatic latent image formed on the image carrier is rendered visible as a toner image by depositing the toner by the developing device, and the toner image is transferred by the transfer device and fixed onto a recording medium by the fixing device and output. The apparatus further includes a density fluctuation meter including a rotary position detector, a density fluctuation detector, and a density fluctuation storage; a density fluctuation extractor unit including a first extractor, a second extractor, and a density fluctuation storage; and a control table generator unit including a control table generator and a control table storage, so that based on the control table stored in the control table storage, the voltage to be applied to the developing device is controlled and the toner image is output.

A correction control method includes performing correction control to bring a control value to a target value or a change through a prediction control system that previously applies a predetermined amount of correction and a predetermined timing. The prediction control system is constructed without performing data offset processing for deriving the predetermined amount of correction and the predetermined timing.

An electrical wire routing device for routing an electric wire between a floor in an automobile and a seat includes a case following parallel to a support rail to which a support body supporting the seat is slidably attached. The case includes a tubular movement section attaching the electric wire thereto, guiding the electric wire to the seat, to which a slider sliding in association with the movement of the seat is slidably attached, and a housing section accommodating the extra length of the electric wire. The movement section and the housing section are provided as separated parts and placed parallel to each other. The extra length of the electric wire extracted from one end portion of the movement section and drawn into the housing section is accommodated in the housing section with the electric wire bent in a U-shape. The electric wire is accommodated in the corrugated tube.

The wiring-harness routing device 1 includes two wiring harness 10, a support body 3 mounted slidably at a rail 2 and supporting a seat, and a protector 4 sliding interlockingly with the support body 3 and leading the two wiring harnesses 10 to the seat. The protector 4 includes a pair of wiring-harness hold portion 43 holding the two wiring harnesses 10 led through an opening 20 into the rail 2 to be arranged in parallel; portion arranged between the pair of wiring-harness hold portions 43, and passing the two wiring harnesses 10 therethrough, and extending with a cylindrical shape so as to go through the slit and be led to an outside of the rail 2; and a mount portion 68 attached at the support body 3 so as to have a gap allowing motion in the widthwise direction of the rail 2.
摘要:
In an image forming apparatus, a first controller forms a first image pattern on an image bearer and determines a first image formation condition based on a detection result of density of a toner image. The first controller then controls a toner image forming device based on the first image formation condition. A second controller forms a second image pattern different from the first image pattern on an image bearer and determines a second image formation condition based on a detection result of density of a toner image. The second controller then controls a toner image forming device based on the second image formation condition.
