20100327515 | Roll-Sheet Feeding Device And Image Forming Apparatus - A roll-sheet feeding device having a roll sheet wound in a roll to feed a portion of the roll sheet to an image forming unit, includes a progressive mechanism to transmit a drive force from a drive source to transfer the portion of the roll sheet from the roll in a progressive direction, a roll-sheet drive mechanism to receive the drive force transmitted via the portion of the roll sheet transferred in the progressive direction, a rewinding mechanism to transfer the portion of the roll sheet in a direction opposite to the progressive direction via the roll-sheet drive mechanism to rewind the roll sheet, and a regenerating mechanism to obtain the drive force from the roll-sheet drive mechanism and transmit the obtained drive force to the progressive mechanism to regenerate the transmitted drive force as another drive force in addition to the drive force from the drive source. | 12-30-2010 |
20120032021 | ROLL MEDIUM HOLDING UNIT, ROLL SHEET FEEDER, AND IMAGE FORMING APPARATUS - A roll medium holding unit is disclosed that includes a core part configured to be inserted in a core pipe of a roll medium; and plural diameter-increasing members configured to be variably arranged at corresponding first positions provided along a periphery of the core part and arranged at corresponding second positions provided away from the core part. The roll medium holding unit is capable of being set in a first holding state where the diameter-increasing members arranged at an outer peripheral surface of the core part support the roll medium with the diameter-increasing members arranged at the corresponding first positions and capable of being set in a second holding state where the core part of a holding member supports the roll medium with the diameter-increasing members arranged at the corresponding second positions. | 02-09-2012 |
20130126659 | MEDIUM SUPPLYING APPARATUS AND IMAGE FORMING APPARATUS - A medium supplying apparatus for applying a back tension opposite to a transferring direction of a rolled medium being transferred by a transfer unit, to the rolled medium, includes a driving unit including a drive gear to be rotated in a forward direction and a reverse direction; a rotation transmitting mechanism that includes a one-way clutch and a torque limiter and transmits a rotational force between the driving unit and a medium rotation shaft that rotatably holds the rolled medium via the one-way clutch and the torque limiter; and a control unit that controls the driving unit to be one of states including being rotated in the forward direction, being rotated in the reverse direction and not being power supplied while the rolled medium is being transferred by the transfer unit to change the strength of the back tension. | 05-23-2013 |
20130222457 | IMAGE FORMING APPARATUS - 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. | 08-29-2013 |

20130164638 | METAL-OXYGEN BATTERY - Aims at providing a metal oxygen battery capable of supplying oxygen and perform charge/discharge stably. A metal oxygen battery | 06-27-2013 |
20130224569 | METAL OXYGEN BATTERY - Provided is a metal oxygen battery having an excellent charge/discharge capacity and cycle performance. A metal oxygen battery includes a positive electrode containing an oxygen-storing material and to which oxygen is applied as an active substance, a negative electrode to which a metal is applied as an active substance, an electrolyte layer disposed between the positive electrode and the negative electrode, and a case hermetically housing the positive electrode, the negative electrode and the electrolyte layer. The oxygen-storing material has the functions of, during discharge, ionizing stored oxygen and releasing ionized oxygen, and causing the ionized oxygen to react with metal ions permeating from the negative electrode through the electrolyte layer into the positive electrode to thereby form a metal oxide, and of, during charge, storing oxygen by reduction of the metal oxide. The metal oxide formed during discharge contains an amorphous oxide. | 08-29-2013 |
