  • Method of removing air bubbles from ink supply passage in ink jet recording apparatus and ink jet recording apparatus capable of employing said method
    Patent number: 6325484
    Abstract: An air-communicated opening (8a) of an ink cartridge (8) connected to an ink jet recording head (7) is sealed to apply negative pressure from the suction device (11) to the recording head (7) through a capping unit (10). Ink is forcibly discharged from the recording head (7) until the internal pressure of the ink cartridge (8) is brought into a condition of equilibrium with the sucking pressure of the suction device (11). Thus, air bubbles are discharged to the outside by force of the flow of ink. Then, the pressure of the ink in the ink cartridge (8) is reduced to the sucking pressure to raise the degree of deaeration of the ink.

  • Current mode asynchronous decision A/D converter
    Patent number: 6326914
    Abstract: An analog-to-digital converter (ADC) for telecommunication applications such as ASDLNDSL UMTS/GPRS wherein the conversion is realized in current mode instead of voltage mode. The power consumption is thereby reduced and the converter is adapted to be used in (low voltage) battery operated products. The structure of the converter is also simplified because summing of currents is easier than summing of voltages. The converter comprises at least a first set of N=64 first current cells (CC) coupled in parallel between lines (L+, L−) of a differential current bus. Each first current cell comprises a current source (ICC) to supply a first additional current (64×Iref) to the current bus under control of first comparator circuits (COMP1+, COMP1−). The first comparator circuits of the current cells are coupled in cascade and activated step-by-step one after each other.

  • Control apparatus for internal combustion engine
    Patent number: 6325047
    Abstract: To exactly obtain a volumetric efficiency or ignition timing corresponding to a shift amount in rotational angle or phase of a camshaft relative to a crank shaft operably connected therewith even if the opening/closing timing of an exhaust valve and an intake valve is changed so as to optimally control an fuel injection amount or ignition timing, the fuel injection amount or the ignition timing is controlled by calculating a fuel control parameter or an ignition timing control parameter on the basis of an intake pressure and a rpm of the engine. When the valve timing is changed, the amount of change in the valve timing is detected so that the fuel control parameter or the ignition timing control parameter is compensated for on the basis of the change amount thus detected.
