    摘要： An ink-jet printing head and an ink-jet printing apparatus can reduce fluctuation of density of an ink ejected from each nozzle by ejecting ink of different densities from the same nozzle without varying size of an ink droplet, or by controlling ejection of a mixture ink, in which a plurality of inks are mixed, for forming an image. The ink-jet printing head includes a plurality of ejection openings for ejecting ink, a plurality of ink passages communicated with the plurality of ejection openings, ink ejecting energy generating elements provided in the plurality of ink passages, a mixing liquid chamber connected to the plurality of ink passages in common, a plurality of individual liquid chambers supplying ink to the mixing liquid chamber, and a valve mechanism provided between the individual liquid chamber and the mixing liquid chamber and controlling supply amount of the inks supplied from the individual liquid chambers.

    摘要： A bus arbiter capable of avoiding needless increase in circuit scale is provided. The bus arbiter controls a bus shared by a CPU (central processing unit) and a plurality of apparatuses for generating addresses. The bus arbiter includes a determination unit for determining if a request of an address is a request of an address where no corresponding device is present, and a processor for passing the request by transmitting an ACK signal without performing a writing operation for a request of a writing operation, and transmitting dummy data and an ACK signal without performing a reading operation for a request of a reading operation, when the determination unit has determined that the request is a request of an address where no corresponding device is present.

    摘要： This invention provides an ink jet printing apparatus and method with an inexpensive arrangement that allows a stable supply of an appropriate voltage to heaters without requiring varying load resistance or changing a power supply voltage. The ink jet printing apparatus of this invention has a plurality of nozzles arrayed in a print head; a plurality of energy generators installed one in each of the nozzles for generating an ejection energy to eject ink from the nozzles, the plurality of energy generators being divided into a plurality of blocks; and a drive controller f or simultaneously driving the energy generators in each block. The drive controller supplies an energy to the energy generators making up each block through different kinds of energy supply paths.
