摘要:
A top cover (17) is provided at an upper position of a supporting structure (12) of heat exchange device (11), and an upper opening (20C) is configured to be provided in a detachable type cover (20) for constituting this top cover (17) at a position corresponding to a clearance (16) between a radiator (13) and an intercooler (15) which overlap in the flowing direction (A) of cooling air. Accordingly, when a cooling fan (7B) is rotatively driven, the upper opening (20C) allows cool cooling air to flow into the supporting structure (12) and to be supplied to the radiator (13) through the clearance (16) between the radiator (13) and the intercooler (15). As a result, only the radiator (13) which overlaps with the intercooler (15) can be efficiently cooled by the cool cooling air from the upper opening (20C).
摘要:
An image forming apparatus, forming a color image by successively superposing color images, formed on image carriers of corresponding image forming parts arranged along a rotational direction of an endless moving member, onto the endless moving member or a recording medium conveyed thereby, includes a first part causing a color registration pattern to be created on the endless moving member or the recording medium; a second part obtaining a color registration pattern signal by detecting the color registration pattern; a third part changing image formation timing in the image forming parts based on the color registration pattern signal; and a fourth part causing the endless moving member to rotate in forward and reverse directions after the creation of the color registration pattern. The second part obtains the color registration pattern signal by detecting the color registration pattern during each of the forward and reverse rotations of the endless moving member.

摘要:
An image forming apparatus enables a high-quality double-side printing of a transfer medium by one-pass method using a simple structure. A latent image is formed and developed on an image carrier (drum) in a process cartridge. A resultant toner image is transferred by a first transfer unit (roller) onto either an upper surface of the transfer medium or a first intermediate transfer body (roller) in a first transfer area. The toner image on the first intermediate transfer body is transferred onto a back surface of the transfer medium in a fourth transfer area via a second intermediate transfer body (belt) and a third intermediate transfer body (roller). The fourth transfer area is located downstream of the first transfer area along a transport path of the transfer medium.
摘要:
A first degradation degree detector detects a first degradation degree of one of a plurality of image forming devices for forming toner images, respectively, which is provided at an extreme downstream position in a direction of rotation of an intermediate transfer member. A first degradation degree judgment device judges whether or not the first degradation degree of the extreme downstream image forming device detected by the first degradation degree detector reaches a first level of deterioration. A bias controller decreases a bias to be applied by a transfer device to transfer the toner images, which are formed by the plurality of image forming devices and transferred on the intermediate transfer member, onto a transfer sheet, when the first degradation degree judgment device judges that the first degradation degree of the extreme downstream image forming device detected by the first degradation degree detector reaches the first level.
摘要:
The frame of a vehicle body is constituted by left and right vertical plates and a bottom plate coupling the vertical plates horizontally. In addition, a control valve device and a control valve device including a plural number of directional control valves are mounted in advance on a single mounting plate together with a correction lever, a plural number of operation levers and link mechanisms to obtain a lever/valve assembly. Then, the mounting plate constituting of the lever/valve assembly is attachable to or detachable from the left vertical plate of the frame by using bolts or the like. As a result, the efficiency of the assembly operation can be improved.
摘要:
A device cover is formed as a whole in a bent L-shape by an upper face covering a device accommodation space from an upper side, a side face covering the device accommodation space from a right side, and a convex curved bent face connecting the upper face and the side face. In addition, the device cover is separated into an upper face separate cover element and a side face separate cover element at a joint position extending in a direction from the front toward the rear and then, these separate cover elements and are integrally connected by the use of a connecting plate.

A semiconductive resin composition includes at least two thermoplastic resins and a conductive filler. Each of the two thermoplastic resins has a sea-island structure, and 40% to 75% of the conductive filler are present in the thermoplastic resin in an island portion of the sea-island structure at an areal ratio of a cross section observed with a scanning electron microscope.
