Abstract: In an ink-jet head device, a main tank, a sub tank and an ink-jet head are mounted in this order in a carriage, with the main tank placed at the top. The main tank, sub tank and ink-jet head are connected to one another by a three-way ink conduit. At a junction of the ink conduit is disposed a three-way switching valve, which selectively switch a path connecting the sub tank to the main tank and a path connecting the sub tank to the ink-jet head, without causing the ink-jet head and the main tank to communicate with each other. As a result, an ink-jet head device and an ink-supplying method are realized, in which the ink-jet head can maintain suitable negative pressure and in which consumption of ink is reduced.

Abstract: When an input power supply fed to a liquid crystal display device is cut off, a gate-on power supply for driving a gate line of a display part is automatically changed from a first power supply that reduces luminance inclination unevenness in the display part to a second power supply that causes residual charges in liquid crystal to be discharged. Consequently, at a normal driving time, a good quality display image with reduced unevenness in luminance inclination can be obtained, and at a power-off time, the display due to the residual charges of the liquid crystal is cleared so that an after image can be prevented from being visible.

Abstract: An optical pickup device has three different light sources, a holographic element, beam splitters, and first and second photodetectors. The beam splitters each change an optical path of a light beam coming from the associated light source toward a recording medium and match an optical axis of the changed optical path with an optical axis passing through the holographic element and the first photodetector. Reflected light from the recording medium is divided into zero-order diffraction light and first-order diffraction light by the holographic element. The first photodetector receives the zero-order diffraction light and obtains an RF signal and a tracking error signal. The second photodetector receives the first-order diffraction light and obtains a focusing error signal.

Abstract: Areas are hierarchically ensured as directories for data to be recorded in advance. Therefore directories and files are continuously arranged as much as possible on a disk, and the number of seeks during data read, which is conventionally large because other data is mixed in the same area, is decreased as few as possible. When the files and directories belonging to directory 1 (DIR1) and directory 2 (DIR2) are recorded on a disk and when the files and directories belonging to directory 1 (DIR1) are recorded in an area-ensuring mode, an area on a disk for the files and directories belonging to the directory 1 (DIR1) is ensured previously. The positions where lower-order Files 1, 2 and directories of the directory 1 (DIR1) are recorded in an area concerning the directory 1 (DIR1) as in the case of File 1-1, File 1-2, and File 12. File 3 of the directory 2 (DIR2) is not recorded in continuous areas for the directory 1 (DIR1).

Abstract: A pseudo print job system and method are provided for managing scan jobs. The method comprises: scanning a document at the scanning device; spooling the scan job in storage; sending a pseudo print job request to the scanning device, from a connected client; despooling the scan job from storage in response to the pseudo print job request; and, sending the scan job to a connected destination. The spooling of the scan job in storage may include storing the scan job in a scanning device internal memory, a network-connected server memory, or a connected client memory. The scan jobs are sent to a destination specified in the pseudo print job request. Sending a pseudo print job request for the scan job includes the use of either a network scan-enabled print driver or an independent network scan application. Either way, the pseudo print job request is sent via the client's print subsystem.
