The present invention is a portable terminal and a display data editing method for the same capable of easily changing preliminarily stored display data to any expression preferable to the user. A display processorcontrols the writing and read-out data in and out of a memory unit, and provides various displays on a display partaccording to registered display data. An editing processoredits the display data on a display and also collectively edits duplicated display data in response to key operation in a key entry unit. A retrieving processorretrieves any duplicated display data in the editing subject display data before change and after change.

Portable terminal and display data editing method for the same

An electronic apparatus () has a plurality of functions. A key code recognizing unit () recognizes an input of a key code for requesting setting of a parameter about a setting particular related to each function. A storage unit () stores handling information () for handling setting restriction, for each setting particular whose parameter is restricted from being set in relation to other setting particulars. When the key code recognizing unit () recognizes an input of a key code for requesting setting of a parameter, a guidance process unit () determines whether setting of the parameter is restricted or not. If setting of the parameter is restricted, the guidance process unit () reads out handling information () for handling the setting restriction from the storage unit () and outputs it to a window control unit (). The window control unit () displays the handling information () on a display unit ().

Electronic apparatus, information output method and program

A DC converter with a halt mode setting is disclosed for preventing the occurrence of over-current while alleviating the increase in the size of circuits, along with a method for setting up such a halt mode. The DC converter includes a semiconductor switch, a clock generator for outputting a clock signal to a gate of the semiconductor switch to be utilized for controlling an on/off time of the semiconductor switch such that a predetermined power is output from the generator, and a drive circuit for switching the semiconductor switch to the continuous-on state according to a halt mode setting requirement regardless of the clock signal, when the semiconductor switch, normally repeating on/off operations responsive to the clock signal, is in its off-state.

DC converter with halt mode setting means

The power circuit includes a switching regulator part, a series regulator part and a control circuit part for controlling operation of the switching regulator and controlling the second predetermined voltage of the series regulator part.

Power circuit and method of rising output voltage of power circuit

A power supply apparatus includes a switching transistor, a transistor control circuit, and a reference voltage generator. The switching transistor performs a switching operation for converting an input source voltage to an output power voltage according to a control signal. The transistor control circuit generates the control signal based on a reference voltage and a feedback voltage associated with the output power voltage. The reference voltage generator generates the reference voltage, increases the reference voltage in a phased manner to increase the output power voltage in a phased manner to a desired value, and decreases the reference voltage to decrease the output power voltage. A power supply method is also described.

Method and apparatus for power supplying capable of effectively eliminating overshoot voltage

In order for a backup battery to prolong a backup time period for a mobile instrument, a control signal Scbecomes either low or high in accordance with a determination that a power supply voltage Vm of a main battery is either lower or higher than a prescribed level Vrequiring backup from the backup battery. A control signal Scalso becomes either low or high in accordance with a determination that a backup voltage Vb of the backup battery is either higher or lower than a power supply voltage Vm supplied by a main battery. When both of the control signals Scand Scare in the high level, a control switch is turned ON so as to stop a current from flowing from the backup battery to the main battery. The control switch is otherwise turned OFF.

Backup time endorsed power supply apparatus

An image forming apparatus of the type forming a toner image on a photoconductive drum or similar image carrier, transferring it to a paper or similar transfer medium via an intermediate transfer body, e.g., belt, and fixing it on the medium by a fixing device is disclosed. Just after the transfer of a toner image of the last color which is to lie over the other toner images on the intermediate transfer belt, the peripheral speed of the belt is switched to a comparatively low speed matching a fixing and paper transport speed. At this instant, the belt is moved away from the drum. The length of the transfer medium and the distance between a paper transfer position and a fixing position is compared. For a relatively short transfer medium, the peripheral speed of the belt is not switched to the low speed.
