  • Patent number: 7244094
    Abstract: An impeller pump for a fluid includes a rotary impeller (10; 20) and a pump casing (4). The pump casing defines a first pump channel (51) and a second pump channel (71). The impeller is disposed within the pump casing and opposes to the first pump channel and the second pump channel, respectively. The fluid discharged from the first pump channel and the fluid discharged from the second pump channel converge at a convergence channel (62). A pulsation canceling device serves to cancel pulsations of the fluid discharged from the first pump channel and the second pump channel, respectively. An impact reducing device (155, 175; 357; 455, 457; 555, 557) serves to reduce impacts produced by at least one of the flow of the fluid from the first pump channel and the flow of the fluid from the second channel.

  • Publication number: 20060061593
    Abstract: While the memory amount is reduced through minimizing correction data prepared in advance, the capability of uniformity correction can be improved, compared to a related art. Correction data for correcting display unevenness between pixels for representative pixel points is stored. Correction data for pixels except for the representative pixel points is calculated by interpolation. The representative pixel points are arranged with a higher density in a pixel region with relatively finer display unevenness.
