| 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 |

| 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 |
