Patent number: 5997133Abstract: 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.Type: GrantFiled: November 20, 1997Date of Patent: December 7, 1999Assignee: NEC CorporationInventors: Hitoshi Takemoto, Tadashi Mizoguchi, Junichi Suetsugu, Hitoshi Minemoto, Kazuo Shima, Yoshihiro Hagiwara, Toru Yakushiji

Patent number: 5152027Abstract: 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.Type: GrantFiled: April 2, 1990Date of Patent: October 6, 1992Assignee: Shop-Vac CorporationInventor: John A.
