  • Patent number: 5997133
    Abstract: An inkjet recording apparatus includes K ejection electrodes and M counter electrodes which are located at a distance from and opposed to the K ejection electrodes. A first voltage pulse is applied to a selected one of N groups of ejection electrodes each group formed by electrically connecting an i.sup.th (1.ltoreq.i.ltoreq.N) ejection electrode for each counter electrode to each other and a second voltage pulse is applied to a selected one of the M counter electrodes. A voltage difference is generated between a group and a counter electrode which are selected from the N groups and the M counter electrodes depending on an input signal, wherein the voltage difference is equal to or greater than a minimum voltage difference which causes ejection of ink from an ejection electrode.

  • Patent number: 5152027
    Abstract: A surface sweeper may include a first pulley driven by the motor, a second pulley on a drive shaft for driving the drive wheel, a third pulley for driving the main brush, and a drive belt interconnecting the first and second pulleys which can be selectively tightened by a clutch for driving the drive wheel. Preferably the drive belt has inherent stiffness whereby it spontaneously loosens unless held in its tightened condition by the clutch. The driveshaft advantageously has two parts separated by a gap, for permitting the drive belt to be placed around the driveshaft without removing the driveshaft from its mount. The two parts may be connected by a sleeve which is biased by a spring into position for drivingly engaging the two parts, and which is slidable out of said position for revealing the gap. The main brush may have structures at its two ends that are similar to each other, for being reversibly mountable in first and second brush bearings.

  • Patent number: 5050160
    Abstract: A method for training an echo canceller of a voice conference system, to cancel an echo by subtracting an estimated echo signal from an actual echo signal, includes the steps of: generating, at a time of a first training session, an initial echo signal and an initial training signal through feeding of a training signal to a loudspeaker and to the echo canceller; obtaining a response characteristic of the echo canceller to the echo signals; storing the initial echo signal and the initial training signal; and training the echo canceller, during subsequent training sessions, by using the stored initial echo signal and the stored training signal.
