    Abstract: A display device controller has digital RGB colour signal lines and horizontal and vertical sync signal lines (7, 8). NAND gates (9) detect in respect of at least one of the RGB colour signal lines when the digital signal on that line corresponds to a black level, and a D/A converter (10) and an adder (+) add to at least one of the horizontal and vertical sync signal lines a signal corresponding to the black level signal so detected.

    Abstract: An FPC cable which is excellent in noise resisting property, manufacturing cost, mounting operability to a carriage, and maintenance. The FPC cable includes a spacer and a reinforcing plate. In the patterned surface of the FPC, a head pad to which a head wire is bonded is formed on a pad forming portion and a preamplifier chip is mounted on a device mounting portion. Wiring patterns are linearly connected between the head pad and the preamplifier chip and between the preamplifier chip and an I/O-side end portion, respectively. In the spacer, a cavity is formed for storing the preamplifier chip. The reinforcing plate is inserted into the space formed by folding back the pad forming portion, and the spacer is engaged with the device mounting device, thereby constituting a magnetic-head-side end portion.

    Abstract: Provided is a superior portable information processing apparatus, having a detachable liquid crystal display panel/input tablet, whereof the liquid crystal display panel/input tablet can be detached from the apparatus even when the main body is powered on, i.e., is being operated. The portable information processing apparatus comprises: support means for detachably supporting a liquid crystal display panel on a main body; detection means for detecting detachment/attachment of the liquid crystal display panel; and first and second connectors for providing a connection for video signal lines and a power line that connect the liquid crystal display panel and the main body. When the liquid crystal display panel is detached from the main body, the first and the second connectors can communicate with each other via a cable. When the detection means detects that the liquid crystal display panel has been detached, the output of video signals from the main body to the display panel is disabled, and then the power supply to the liquid crystal display panel is halted (local suspend). As a result, the disorderly open state of the signal output line and the power line to the display panel can be avoided, and the deterioration of hardware can be prevented. In parallel to the local suspend operation, the main body of the apparatus saves data required for the resumption of a task, and halts the operation of the entire system (system suspend). As a result of the system suspend function, a state of a processed application can be stored immediately before the liquid crystal display panel was removed, and when the display panel is reattached, the halted application is smoothly resumed.
