    摘要： A liquid crystal drive circuit includes a first buffer circuit for outputting a selection high level segment voltage V0' using a nonselection high level common voltage V1 from a common voltage generator as a reference, and a first operational amplifier for outputting a nonselection high level segment voltage V2' having an inverted voltage level of the selection high level segment voltage. The liquid crystal drive circuit also includes a second buffer circuit for outputting a selection low level segment voltage V5' using a nonselection low level common voltage V4 as a reference, and an operational amplifier for outputting a nonselection low level segment voltage V3' having an inverted voltage level of the nonselection low level segment voltage.

    摘要： A signal electrode drive circuit for driving a liquid crystal display panel includes a latch circuit for latching a digitized video signal, a buffer, a graduation signal-forming circuit, an intensity modulation pulse-generating circuit, and an analog multiplexer. The latch circuit holds the video data only once during one horizontal scanning period until a next latch pulse M is generated, thus considerably reducing current dissipation.

    摘要： In a signal electrode drive circuit of an image display apparatus, the latch pulses are sequentially shifted for a plurality of latch circuits so as to sequentially latch the digital image data, and the signal electrode of the dot-matrix type display panel is driven by the signal having a plurality of gradation, based upon the digital image data latched in the latch circuits. The image input data are alternately read out via the buffer circuits by two-phase clock pulses, the input data are transferred to the latch circuits in response to the two-phase clock pulses, and, as a consequence, image data of higher transfer frequency can be satisfactorily processed.

    摘要： An ink cartridge for a printing apparatus providing ink to a print head through a tapered ink supply needle and removably attached to the print head. The ink cartridge comprises an ink chamber for containing ink, an ink supply port, a packing member and a valve device. The ink supply port supplies ink from the ink chamber to the print head of the printing apparatus, the ink supply port comprising an external opening. The packing member is provided in the ink supply port and forms an ink channel for allowing a flow of ink. The packing member seals the ink supply needle of the printing apparatus by fitting therewith. The valve device is contained in the ink supply port and elastically abuts against the packing member. The valve, device selectively opens and closes the ink channel in conjunction with the ink supply needle.
