A fluid feeding pump which varies a volume of a pump chamber and thus feeds a fluid out of the pump chamber, includes: a piezoelectric element which accumulates electric charges inside when a voltage is applied, and which deforms according to an amount of accumulated electric charges and thus increases or decreases the volume of the pump chamber; a drive unit which applies a drive signal with a waveform increasing to a predetermined maximum voltage and then decreasing, and thus drives the piezoelectric element; and an air bubble determining unit which detects a current flowing through the piezoelectric element within a predetermined period after the drive signal is applied to the piezoelectric element, and thus determines whether there are air bubbles in the pump chamber or not.

A liquid crystal display device (100) of the present invention includes: a liquid crystal panel (20) including: an active matrix substrate (21); a counter substrate (22); and a liquid crystal layer (23) provided between the active matrix substrate (21) and the counter substrate (22); and a backlight (10) illuminating the liquid crystal panel. The liquid crystal display device (100) has an area sensor function for detecting an external input position, and further includes a reflectance changing section (50) that reduces a reflectance of light from the backlight (10) in response to application of pressure on a panel surface (100a). The reflectance changing section (50) is configured so that in a state where no pressure is applied on the panel surface (100a), an air layer (50c) is formed between two elastic films (50a and 50b) whereas in a state where pressure is applied on the panel surface (100a), the two elastic films (50a and 50b) contact each other.

In a liquid crystal display device having a light diffuser, a desired luminance distribution is realized and displaying with a high contrast ratio across a broad angle range is performed. A liquid crystal display device according to the present invention includes a liquid crystal display panel for modulating light emitted from a light source, and a light diffuser being disposed at a viewer's side of the liquid crystal display panel. The light diffuser is a prism sheet including a plurality of prisms, each prism having: a first prism section including a first slope slanted at a first angle with respect to the display surface normal direction; and a second prism section including a second slope slanted with respect to the display surface normal direction at a second angle different from the first angle and being disposed at the viewer's side of the first prism section.

A wiring substrate for mounting semiconductors is provided with an insulation film, wires formed in the insulation film, and a plurality of electrode pads that electrically connect to the wires through vias. The electrode pads are provided to have their surfaces exposed to both of the front surface and the rear surface of the insulation film, and at least a part of the side surface of the electrode pads is buried in the insulation film. The insulation film is formed by forming electrode pads on the respective two metallic plates, thereafter, laminating an insulation layer and wires on the respective metallic plates to cover the electrode pad, and adhering the insulation layers to each other for integration, and thereafter, removing the metallic plates.

When executing the gradation lowering processing to a data area in the lower side in multi-valued print data 403, an error generated by executing the gradation lowering processing to the data area in the lower side is stored in an information storage area 901B. On the other hand, the error thus distributed and stored is used for executing the gradation lowering processing to the data area “J” (Jth line) in multi-valued print data 404 relating to the next scan. In this way the error generated when executing the gradation lowering processing to the multi-valued print data is stored, which is used at the time of executing the gradation lowering processing to the multi-valued print data relating to the next scan. Therefore, the density is stored by receiving and delivering the error between the multi-valued print data in a scan unit.
摘要:
Multi-valued image data stored in an input image buffer are read out for each time of scans, and the color space conversion and image distribution are performed to read multi-valued image data. The binarized result is sent to the print buffer and at the same time, is accumulated as the print information to execute processing of reflecting it to the image distribution processing of the next pass. It is possible to appropriately restrict the density fluctuation due to the print position shift between planes without providing pixels where dots are overlapped and printed more than necessary. With this, by accumulating the multi-valued image data at the stage of RGB in the input image buffer to read out data stored in input image buffer for executing processing, a capacity required for input image buffer does not change even if the number of the ink colors provided on the printing apparatus increases.
摘要:
The quantity processing is executed to data distributed for each color. Binary data obtained by this quantization processing are selected only in regard to a color generating print quantity information. Filtering processing is executed to the binary data of the selected color to generate the print quantity information. In the quantization processing for a second plane, data found by converting the print quantity information generated in the first plane processing into a minus value are added to the multi-valued data. In the quantization processing in the second plane added, the value of the multi-valued data is made small and in the quantity, probability that the multi-valued data become binary data printing the dots is made small. That is, a ratio where dots in the first plane and dots in the second plane overlap and are formed can be made small.
