摘要： There is provided a method of manufacturing liquid transporting apparatus including: providing a channel unit; providing a piezoelectric actuator having a first and second active portion corresponding to a central portion and an outer periphery portion of the pressure chamber, respectively. The first and second active portions are sandwiched between an upper electrode and an intermediate electrode, and between the upper electrode and a lower electrode, respectively. The method further includes joining the channel unit and the piezoelectric actuator by positioning such that the intermediate electrode overlaps the central portion of the pressure chamber. Accordingly, since it is possible to make the first active portion overlap the central portion of the pressure chamber, it is possible to apply a appropriate pressure to the liquid in the pressure chamber without excessively small deformation of the first active portion.

摘要： A recess is formed on an upper surface of a vibration plate at a position corresponding to a pressure chamber. Next, a low-elasticity material having a lower modulus of elasticity than the vibration plate is filled in the recess. Then, aerosol including a piezoelectric material particles and carrier gas is sprayed on the upper surface of the vibration plate to form a piezoelectric layer. At this time, the particles of the piezoelectric material do not adhere to a surface of the low-elasticity material filled in the recess, and hence the piezoelectric layer can be formed only in an area excluding the surface of the low-elasticity material. Thus, there is provided a method of manufacturing a piezoelectric actuator, the method capable of easily preventing, when forming the piezoelectric layer by an aerosol deposition method, formation of the piezoelectric layer on a surface of the recess.

摘要： A liquid-droplet jetting apparatus such as an ink-jet printer makes a meniscus of an ink in a nozzle vibrate by applying a no-jetting drive pulse which does not jet the ink. An operation of outputting two no-jetting drive pulses in one cycle is repeated for 100 to 150, and then stopped for 100 to 150 cycles. A pulse width Tp of the no-jetting drive pulses, an interval Tw between two no-jetting drive pulses, and a time AL in which a pressure wave in an ink channel is propagated one way are set to be in a range 0.1 AL≦Tp≦0.2 AL, and 0.2 AL≦Tw≦4.5 AL. Accordingly, it is possible to prevent assuredly, thickening of a liquid such as an ink in the nozzle, and to reduce a generation of a defect in jetting of a liquid droplet.

摘要： When a new target is detected, if it is determined that the distance difference between the newly detected target and the previously detected target is within a predetermined range, the difference between the relative velocity of the newly detected target and the relative velocity of the previously detected target is obtained to determine whether the difference is greater than a predetermined value &Dgr;Va, and when the difference is greater than the predetermined value, it is determined that the new target is a target obtained as a result of mispairing. Further, when the difference between the relative velocity of the newly detected target and the relative velocity of the previously detected target is greater than the predetermined value &Dgr;Va, then the difference between a distance derivative of the newly detected target over a prescribe time and the relative velocity of the previously detected target is obtained, and when the difference is greater than a predetermined value &Dgr;Vb which is smaller than the predetermined value &Dgr;Va, it is determined that the new target is a target obtained as a result of mispairing.
