| 20090124298 | MOBILE PHONE TERMINAL AND COMMUNICATION SYSTEM - Disclosed is a mobile phone terminal with a battery pack containing a retraceable battery as power supply, and transmitting and receiving radio-signals to and from a mobile phone system base transceiver station. The mobile phone terminal includes a data communication terminal communicating data with the battery pack, an intermittent receiving processor periodically carrying out intermittent receiving processing via the base transceiver station when the mobile phone terminal is in a standby operation, and a battery status determining unit transmitting, while the intermittent receiving processor is carrying out intermittent receiving processing, an activating signal to the battery pack via the data communication terminal and reading battery status data from the activated battery pack. | 05-14-2009 |
| 20090124299 | MOBILE PHONE TERMINAL AND CHARGING SYSTEM - Disclosed is a mobile terminal incorporating a battery pack utilized as power supply. The mobile terminal includes a positive terminal connected to a battery pack positive electrode, a negative terminal connected to a battery pack negative electrode, a data communication terminal communicating with a circuit in the battery pack, a charge control unit controlling charging of the battery pack via the positive terminal, and a reference voltage output unit outputting reference voltage. The terminal further includes a dividing resistor and a thermistor connected in series between the reference voltage output unit and the negative terminal, a temperature detector detecting temperature, and stopping charging of the battery pack based on the detected temperature, and a switching device controlling the voltage at the predetermined portion. The terminal still further includes a control unit communicating with the circuit in the battery pack via the data communication terminal, and changing the voltage at the predetermined portion when notified abnormality from the battery pack. | 05-14-2009 |
| 20090135633 | Ac Adapter, Electronic Apparatus and Power Supply System - An AC adapter includes an AC/DC converter device for transforming an alternating-current power to a direct-current power, a power supply line that supplies the direct-current power converted by the AC/DC converter device to an electronic apparatus, and a memory for storing an AC adapter ID that identifies the AC adapter. | 05-28-2009 |

| 20100102505 | REMAINING SHEET VOLUME DETECTING APPARATUS AND IMAGE FORMING APPARATUS - A remaining sheet volume detecting apparatus includes a loading unit that loads a sheet; a moving unit that moves the loading unit to a feed position of the loaded sheet; a feeding unit that feeds the sheet from the loading unit; a sheet thickness detecting unit that detects a thickness of the sheet; a load thickness detecting unit that detects that thickness of the loaded sheet within the loading unit, gradually decreasing; and a remaining sheet volume calculating unit that calculates a remaining volume within the loading unit based on the certain load thickness detected by the load thickness detecting unit and the sheet thickness detected by the sheet thickness detecting unit, each time a sheet is fed by the feeding unit after the load thickness detecting unit detects that the thickness of the loaded sheet within the loading unit has reached the certain load thickness. | 04-29-2010 |
| 20100104337 | SHEET FEEDING DEVICE AND IMAGE FORMING APPARATUS - A sheet feeding device includes a sheet storing unit in which sheets are stacked; a lifting unit that lifts and lowers the sheets; an air blowing unit that blows air to an end faces of the stacked sheets; a feeding roller that is pressed against an upper surface of an uppermost sheet of the sheets and feeds the uppermost sheet by rotating; and a supplying roller that supplies the uppermost sheet, wherein the lifting unit is driven so that height of the uppermost sheet, which is fed by the feeding roller while air is blown by the air blowing unit, is set to be lower than height of the uppermost sheet, which is fed by the feeding roller while air is not blown by the air blowing unit. | 04-29-2010 |
| 20100123280 | SHEET FEEDER AND IMAGE FORMING APPARATUS - There is provided a sheet feeder including: a lifting unit that lifts a loading portion having a recording medium loaded thereon; a position detecting unit that detects whether the uppermost surface of the recording medium is disposed at a predetermined first position; a sheet feed mechanism that feeds the recording medium from the loading portion; a thickness detecting unit that detects thickness of the recording medium fed by the sheet feeding mechanism; and a control unit that, when the position detecting unit detects that the uppermost surface of the recording medium is disposed at the first position, controls the lifting unit such that the uppermost surface of the recording medium is lifted up to a second position that is higher than the first position by a distance determined based on cumulative value of the thickness of the recording medium detected by the thickness detecting unit. | 05-20-2010 |
| 20100133745 | REMAINING SHEET VOLUME DETECTING APPARATUS AND IMAGE FORMING APPARATUS - A remaining sheet volume detecting apparatus includes a loading unit that loads a sheet; a driving unit that lifts up the loading unit to a feed position of a loaded sheet; a feeding unit that feeds a sheet from the loading unit that has reached the feed position; a load thickness detecting unit that detects a load thickness of sheets within the loading unit based on a movement amount of the loading unit until the loading unit reaches the sheet feed position; a sheet thickness detecting unit that detects a thickness of a sheet fed by the feeding unit from the loading unit that has reached the feed position; and a remaining sheet volume calculating unit that calculates remaining sheet volume within the loading unit. | 06-03-2010 |
