摘要： The ink-jet print head 23 is provided with a sloped surface 18 on the inner side surface between the inflow channel 16 and the ink supply channel 14. The sloped surface 18 gradually increases the cross-sectional area of the ink flow path 45 from the inflow channel 16 toward the ink supply channel 14. Accordingly, as the ink flows along the sloped surface 18 into the ink supply channel 14, the rate of flow of the ink gradually decreases due to the increased cross-sectional area provided by the sloped surface 18. As a result, the liquid ink flows more gently into the ink supply channel 14.

摘要： An ink jet print head includes a plural number of piezoelectric vibrators (300) each consisting of a lower electrode film (60), a piezoelectric film (70) and an upper electrode film (80). The piezoelectric film and the upper electrode film of each piezoelectric vibrator are formed within the region facing each pressure generating chamber (12). The lower electrode films interconnect portions of the regions facing the pressure generating chambers and are electrically continuous to a wiring pattern connected to an external circuit; and in each of the portions of the regions facing the pressure generating chambers, each portion not having the piezoelectric vibrator is removed except a part thereof. Such a structure secures a satisfactory function of the lower electrode layer as a common electrode, increases a quantity of displacement of the piezoelectric vibrator while keeping a low compliance, increases an ink discharging speed, and reduces a drive voltage.

摘要： In an ink jet recording head having a structure wherein grooves (3) are formed on a piezo-electric ceramic substrate (1) by cutting work and the resulting side walls (4) of the grooves are driven to thereby jet ink in the grooves, fine cracks appear in the surface layer portion of the side wall during the cutting work. The cracks occurring in the surface layer portion of the side walls (4) are penetrated by an oxide (5) so as to mend them. The piezo-electric ceramic substrate with the grooves is coated with a solution obtained by dissolving the constituent elements of the oxide in a solvent, and is fired so that the side walls are reinforced.

摘要： This invention provides, in a novel liquid discharge method utilizing a movable member, a configuration for detecting presence or absence of liquid in the liquid path or discharge state of the liquid. In an embodiment of this invention, the element substrate of the liquid discharge head is rendered electrically conductive and a partition wall for separating a liquid path for the liquid to be discharged and a liquid path for generating energy for liquid discharge upon heating is also rendered electrically conductive, and a detecting pulse is applied to the partition wall to detect the difference in potential or the variation in electrostatic capacitance between the element substrate and the partition wall, whereby the presence or absence of liquid in the small liquid path is detected. Also in another embodiment, the electrostatic capacitance between a fixed electrode provided in a fixed position of the liquid discharge head and a movable electrode provided on the movable member is detected, and the discharge state of the liquid is judged according to the function state of the movable member.
