Filed: 2000-04-28
Abstract: PROBLEM TO BE SOLVED: To propose a pipe joint which can allow a so-called required adjustment work, thereby can attain a reliable connection of the pipe and can eliminate a burdensome connection work. SOLUTION: A hole is provided on a ring holding section penetrating therethrough to the outside of a receiving mouth, a ring radius expansion member is inserted beforehand into the hole from outside the receiving mouth and is fitted into a split of a split ring to keep expanding the radius of the split ring larger than the outer diameter of the pipe and thereby the insertion to and the withdrawal from the pipe to be connected can be done easily during the connection work.

Title: Method for driving ink jet head
Inventor: KUSUNOKI MASAMUNE
IPC: B41J2/045
Filed: 2000-05-01
Abstract: PROBLEM TO BE SOLVED: To increase a printing speed and realize high-quality gradational printing by controlling a quantity of ink drops to be discharged from the same nozzles by a reduced number of pulses. SOLUTION: Immediately after a first pulse voltage is raised, a diaphragm is gradually attracted to discrete electrodes by an electrostatic force generated between the diaphragm and the discrete electrodes. When the first pulse voltage falls, the diaphragm starts to gradually separate from the discrete electrodes. If a driving interval Td1 is short, a second pulse voltage is impressed before the diaphragm separates from the discrete electrodes, and the diaphragm is attracted to the discrete electrodes because the same electrostatic force as above is generated. A pressure wave to discharge the ink into a discharge chamber is not generated by the first pulse voltage and therefore the ink is prevented from being discharged.  When the second pulse voltage falls, the diaphragm starts to gradually separate from the discrete electrodes and finally the pressure wave to discharge the ink into the discharge chamber is generated. The ink of an ink discharge velocity of Vj2 and a volume of ink drops of Mj2 is discharged.
