Abstract: There is provided a tablet printing apparatus that can perform printing at a high speed on tablets arbitrarily supplied in volume at irregular intervals and has a high printing quality. A tablet printing apparatus 1 for multicolor printing on tablets T comprises a conveying belt 24 for conveying the tablets T in a moving direction A1-A2, an inkjet printer 42 disposed in the middle of the moving direction A1-A2 of the conveying belt 24 for performing non-contact printing onto surfaces of the tablets T conveyed by the conveying belt 24, an encoder 28 and a tablet sensor 29 for detecting moving positions of the tablets T conveyed by the conveying belt 24, and a unit control substrate 32 for controlling printing timing on the tablets T of the inject printer 42 or 46 based on the moving conditions or/and the moving positions of the tablets T detected by the encoder 28 and the tablet sensor 29.

Abstract: This invention provides a seed-sorting apparatus that includes an alignment trough having a plurality of grooves into which the seeds are distributed, a line sensor camera for inspecting the seeds, a nozzle device having a number of nozzles that is the same as the number of grooves on the upper surface of the alignment trough, and a control unit. The control unit, through a series of calculations, is capable of differentiating between different types of seeds and can direct a seed sorting and sucking device to suck the seed.

Abstract: A display panel of the liquid crystal type provides a positive color display of segments or unit display areas using a reduced number of divided electrodes and an increased number of different driving signals. On one side of the panel there is a separate electrode encompassing each display area and all such electrodes include a display area. On the other side there are several common electrodes, each encompassing at least one display area and all cumulatively encompassing all of the display areas. A display area is selected for display by applying driving signals to its opposed electrodes such that substantially zero voltage is across the selected display area thereby leaving colored appearance in the selected display area. All other display areas and background areas are decolored by applying to the respective opposed electrodes driving signals resulting in a liquid crystal threshold voltage being applied across said non-selected display areas and said background areas.

Abstract: A liquid crystal cell includes a nematic liquid crystal of negative dielectric anisotropy is disposed between a pair of transparent electrode substrates. The electrode substrates have on their inner surfaces small grooves formed parallel to each other, the grooves on one surface being perpendicular to those on the other surface. In the absence of a voltage applied between the substrates, the long axes of the liquid crystal molecules are perpendicular to the inner surfaces of the electrode substrates. The addition of a small amount of a cholesteric liquid crystal material markedly improves the contrast of the display.
