20090302531 | BELTLESS TANDEM-TYPE IMAGE FORMING APPARATUS - In a beltless tandem-type image forming apparatus of the invention, a plurality of pairs of transfer rollers are placed side by side at intervals along a conveying direction of sheets. A control section independently conveys sheets in sequence through nip sections of respective pairs of transfer rollers driven by a driving section while sequentially transferring images formed by an imaging section onto the sheets. Conveying speeds of the respective pairs of transfer rollers controlled by the driving section are gradually decreased for every pair of transfer rollers from an upstream side toward a downstream side along a conveying direction of the sheets, and consequently, a driving period for driving the respective pairs of transfer rollers to convey each sheet is gradually increased for every pair of transfer rollers from the upstream side toward the downstream side along the conveying direction of the sheets. The control section performs control so that an imaging period by the imaging section is synchronized with a driving period by the driving section in every pair of transfer rollers. | 12-10-2009 |
20110052267 | IMAGING UNIT AND IMAGE FORMATION APPARATUS PROVIDED WITH THE SAME - In a single-body type imaging unit including a toner bottle provided with a drive shaft, and a print unit provided with a drive shaft, the toner bottle and the print unit are coupled to each other via an elastic member. | 03-03-2011 |
20110229818 | IMAGE FORMING APPARATUS AND METHOD - An image forming apparatus includes a developing device that uses a developer carrier to advance to an image carrier a developer including a toner and a carrier and supplies the toner to the image carrier by applying a developing bias between the developer carrier and the image carrier. In the image forming apparatus, the following operation is performed before the developer in the developing device is taken out. The toner is supplied to the image carrier by applying the developing bias between the developer carrier and the image carrier, the developing bias increased in a direction to supply the toner to the image carrier. The toner supplied onto the image carrier is not transferred to a transfer receiving material but is advanced into a toner recovery device for recovery. The recovered toner is prevented from being returned to the developing device. | 09-22-2011 |
20130241134 | SHEET FEEDING DEVICE CAPABLE OF SKEW CORRECTION AND IMAGE FORMING APPARATUS INCLUDING THE SAME - An image forming apparatus includes a sheet feeding device that corrects skew of a sheet before feeding the sheet to a transfer position for image formation. The sheet feeding device comprises a driver, a feeder roller unit provided with a feeder roller rotationally driven by the driver and a separation roller, and two resist roller units each provided with a primary and a secondary resist roller. The resist roller units cause formation of a loop in the sheet between the resist roller units and the feeder roller unit during skew correction. When viewed in a direction of a rotational axis of the feeder roller, the first resist rollers and the feeder roller overlap at least partially, and the pressing member and the second resist rollers do not overlap. The first resist rollers and the feeder roller occupy different positions with respect to the direction of the rotational axis. | 09-19-2013 |
20130259554 | IMAGE FORMING APPARATUS - An image forming apparatus that is orientatable in either a first position or a second position, the second position being different from the first position in inclination with respect to a horizontal plane, comprising: a platform configured to be stacked with a plurality of recording sheets used for image formation; a pickup roller in contact with the recording sheets and configured to pick up the recording sheets one at a time; a pressing member applying pressure to the platform against the pick-up roller; and a pressure changer causing the pressing member to change an amount of the pressure according to whether the image forming apparatus is in the first position or in the second position. | 10-03-2013 |
20130302056 | IMAGE FORMING APPARATUS CAPABLE OF STABLY DETECTING TEMPERATURE OF FIXING DEVICE REGARDLESS OF ORIENTATION OF THE IMAGE FORMING APPARATUS - An image forming apparatus orientatable in either a first position or a second position, the second position being different from the first position in inclination with respect to a horizontal plane, comprising: a fixing device including a heating roller and a pressurizing member, pressing the pressurizing member against a surface of the heating roller to form a fixing nip, and thermally fixing a toner image on a recording sheet passing through the fixing nip; at least one temperature detector detecting surface temperature of the heating roller without contact with the surface; a heater heating the heating roller; a controller controlling the heater according to the surface temperature, thereby controlling the surface temperature; and a switcher switching a detection point of the temperature detector between a first and a second detection point according to whether the image forming apparatus is in the first or the second position. | 11-14-2013 |

20100003581 | ELECTRIC POWER STORAGE APPARATUS - An electric power storage apparatus including a housing, a partition which is placed in the housing to form a first housing portion and a second housing portion, a electric power storage unit which is housed in the first housing portion, a coolant which is housed in the first housing portion and is provided for cooling the electric power storage unit, and a pressure release means for releasing an internal pressure of the first housing portion to the second housing portion in an abnormal state of the electric power storage unit in which gas is produced in the electric power storage unit. | 01-07-2010 |
20100099015 | POWER SUPPLY APPARATUS FOR A VEHICLE - A power supply apparatus in which a power supply body and coolant that cools the power supply body are housed in a power supply case, and in which the power supply case contacts a heat transmitting member, includes a first housing portion that is within the power supply case and houses the power supply body; a second housing portion that is within the power supply case and positioned on the heat transmitting member side of the first housing portion; a dividing plate that allows the coolant to move between the first housing portion and the second housing portion; and circulating means for circulating the coolant between the first housing portion and the second housing portion. | 04-22-2010 |
20100297483 | ELECTRIC STORAGE DEVICE AND VEHICLE - An electric storage device includes a plurality of electric storage elements each having a terminal at each end, and a support mechanism which supports the plurality of electric storage elements on both end sides of each of the electric storage elements, and a heat generator which is provided for a portion of the support mechanism that supports at least one end side of each of the electric storage elements and is capable of generating heat. | 11-25-2010 |
20120068532 | POWER SUPPLY APPARATUS AND VEHICLE - A relay that is electrically connected/disconnected to/from a battery in parallel with a smoothing capacitor on an inverter side with respect to a system main relay is provided. Thus, when the system is turned off, the battery and electrode buses are electrically disconnected from each other by the system main relay, and the positive electrode bus is thereby connected to the negative electrode bus by the relay. As a result, electric power accumulated in the smoothing capacitor is more reliably and more swiftly discharged. | 03-22-2012 |
20120112754 | APPARATUS QUANTIFYING STATE-OF-CHARGE OF VEHICLE-MOUNTED RECHARGEABLE BATTERY - A rechargeable battery state-of-charge quantifying apparatus for use in a vehicle equipped with an electric motor and a rechargeable battery which supplies electric power to the motor to produce a driving torque. The apparatus quantifies a state-of-charge of the rechargeable battery and defines a minimum value of a state-of-charge of the rechargeable battery at which the rechargeable battery is permitted to produce a degree of electric power required to run the vehicle as a lower limit. The lower limit is increased as the rechargeable battery ages, thereby ensuring the stability in supplying the amount of electric power to the motor which is required to run the vehicle regardless of aging of the battery. | 05-10-2012 |
