摘要:
A heating element for heating fluid flowing therethrough, including an electrically conductive honeycomb structure, electrodes electrically connected to the honeycomb structure for applying an electric current to the honeycomb structure, wherein the honeycomb structure has a front region which is adapted to heat more quickly than a back region of the honeycomb structure. To this end, the honeycomb structure may include at least one gap for obstructing electric current flow, the gap extending through the partition walls and terminating before reaching the front end of the honeycomb structure. Alternatively, the front region may be heated more quickly than the back region by providing at least one depression formed the back end of the honeycomb structure, such that the front region extends from a terminating end of the depression toward the front end of the honeycomb structure. A catalytic converter incorporating the heating element is also provided.

A honeycomb heater includes a honeycomb structure having a periphery, a front end, and a back end, including a plurality of passages which are defined by partition walls and extend in an axial direction of the honeycomb structure, the honeycomb structure being electrically conductive, whereby fluid flows through the passages from the front end to the back end; and a device for applying electric current to the honeycomb structure so as to generate heat; wherein at least one gap for obstructing electric current extends through the partition walls from the back end toward the front end but does not reach the front end so that, upon applying electric current to the honeycomb structure, a front region of the honeycomb structure heats more quickly than a back region of the honeycomb structure thereby a catalyst composition loaded onto the front region is activated earlier. Slit may extend between the front end and the back end. The back end may be depressed so that a front region which is located between the depression and the front end heats more quickly than a back region of the honeycomb structure. A catalytic converter includes: (A) the honeycomb heater; and (B) a catalyst element, which is arranged downstream of the honeycomb heater, including: a monolithic structure including a plurality of passages which are defined by partition walls; and a catalyst composition loaded on at least a part of the partition walls of the monolithic structure, the catalyst composition including: an inorganic oxide resistant to heat; and a catalytically active component, loaded on the inorganic oxide, including an element selected from the group consisting of platinum, palladium, rhodium, and iridium.

A conveying device includes a blower, a wind-permeable sheet material supporter, and a conveyor. The blower blows air toward a sheet material. The sheet material supporter supports a center region of the sheet material from a back side of a blown surface of the sheet material. The conveyor conveys the sheet material through a blowing region blown by the blower, while sandwiching an end region of the sheet material in a sheet-material width direction perpendicular to a sheet-material conveyance direction in which the sheet material is conveyed by the conveyor.

An interlocking mechanism includes an axial member reciprocating in a width direction of arrangement of first and second front doors by linking with an opening/closing operation of a side door. A stop member is provided rotatably and fixed in the width direction to the axial member. A restriction member presses the axial member toward the side door and having a pressing/urging member that urges the stop member in one of rotating directions. A pressing claw presses the stop member in the other of the rotating directions in a state where the second front door and the side door are closed. A restriction claw abuts on the stop member when the first front door is closed in a state where at least one of the side door and the second front door is open. An interlock switch is actuated by an actuator being inserted into the interlock switch.

A sheet cutting device includes a cutter including opposed blades to cut a sheet fed along a sheet feed path to the device, a cutter holder holding the cutter and reciprocally movable in a width direction of the sheet perpendicular to a sheet feed direction in which the sheet is fed, and a guide member including a first path to guide the holder in the width direction of the sheet to cut the sheet with the cutter and a second path to guide the holder in the width direction after the sheet is cut. The second path is disposed away from the first path in a thickness direction of the sheet perpendicular to both the sheet feed direction and the width direction of the sheet. When the holder moves along the second path, the holder is retracted away from the sheet feed path in the thickness direction of the sheet.

An image forming apparatus includes a medium that is a long roll wound around a core member; a feeding unit configured to feed the medium; an image forming unit configured to form an image on the medium; a fixed roll end detecting unit configured to detect an end of the medium whose end is fixed to the core member; a determining unit configured to determine whether to stop, for a time period, the medium on which the image has been formed by the image forming unit, when the fixed roll end detecting unit detects the end of the medium; and a control unit configured to stop an operation of the feeding unit when the determining unit determines to stop the medium for the time period, and to cause the feeding unit to perform an operation of winding back the medium when the time period has elapsed.
摘要:
An image forming apparatus including an image reading unit to read an image of a document, disposed in an upper portion of the image forming apparatus; an image forming unit to form the image on a sheet, disposed below the image reading unit; at least upper and lower sheet roll supporters provided one above the other below the image forming unit to support a sheet roll, the lower sheet roll supporter offset proximally toward a front surface of the image forming apparatus from the upper sheet roll supporter; and multiple openings provided in the front surface of the image forming apparatus for the at least upper and lower sheet roll supporters through which the sheet roll is set to the at least upper and lower sheet roll supporters from a front surface side of the image forming apparatus.
