摘要： An ink-jet head includes pressure chambers arranged in a row in a row-direction, and a manifold flow passage communicated with the pressure chambers and extending in the row-direction. An ink inflow port is formed at one end of the manifold flow passage. The manifold flow passage has a main portion, a connecting portion, and an extended portion which are arranged in this order from a side close to the ink inflow port. The manifold flow passage is communicated with the pressure chambers at the main portion. The main portion has a constant cross-sectional area greater than that of the connecting portion. A cross-sectional area of the extended portion is greater than that of the connecting portion. The pressure wave, generated in the pressure chamber and propagated to the manifold flow passage, can be efficiently attenuated by the manifold flow passage constructed as described above.

摘要： In an ink-jet head having a plurality of nozzles for discharging liquid droplets, vibration is generated in a direction connecting two nozzles, of the nozzles, by the discharge operation performed at least one of the nozzles. In particular, when the printing frequency is in the vicinity of the secondary mode frequency (for example, 27.5 kHz) of the proper vibration of the ink-jet head, the crosstalk easily arises. The crosstalk is hardly caused when the ratio of the secondary mode frequency of the ink-jet head to the printing frequency is any one of a value of not more than 0.85, a value in a range of 1.25 to 1.96, and a value of not less than 4.59.

摘要： A droplet-jetting device, which is usable for an ink-jet recording apparatus, comprises a pressure chamber disposed between a cavity plate and a pressure-generating section of a piezoelectric actuator. The pressure-generating section and the cavity plate are connected by a connecting section. When a voltage is applied to the piezoelectric actuator, the pressure-generating section is elongated to depress the bottom of the pressure chamber downwardly so that the volume of the pressure chamber is increased. The droplet-jetting device is realized, in which the area of arrangement of the pressure-generating section is decreased to suppress the electrostatic capacity and the pull-eject can be performed by applying the voltage only when the device is driven.

摘要： In a picture compression managing apparatus, a reduced picture producing section (23, 26) produces, in response to an index affix request, a reduced input picture by reducing a current input picture of a succession of input pictures included in a picture file which is subjected to picture compression. The reduced picture producing section carries out at least one of output of the reduced input picture to a display unit and storage of the reduced input picture into the recording medium. An index producing section (13, 25) produces, in response to the index affix request, a marking position which is a position of the current input picture with respect to a leading position of the picture file. The index producing section carries out storage of the marking position as a particular index into the recording medium. A reference frame producing section (21, 27) produces at least one of remaining pictures of a succession of the input pictures. The above-mentioned at least one of remaining pictures is used as at least one reference frame in later compressing the current input picture into a compressed picture. The reference frame producing section carries out storage of the above-mentioned at least one reference frame into the recording medium.

摘要： A structure of an air blowout outlet for a vehicle, includes a case having an air inlet through which air is supplied. A pair of first wall sections extend in a longitudinal direction of the case. A pair of second wall sections are provided in such a manner that each second wall section connects end portions of the first wall sections. The first wall sections and the second wall sections define an air outlet through which air supplied from the air inlet is blown out. A first guide is formed at an inner surface of the second wall sections to extend in a longitudinal direction of the case so as to squeeze air introduced from the air inlet. Additionally, a second guide is formed at an inner surface of the first wall sections. A central portion of the second guide in the longitudinal direction of the case extends larger than an end portion of the second guide in the longitudinal direction of the case so that the central portion squeezes air larger than the end portion.

摘要： A moving picture coding method and apparatus is provided that performs motion compensation interframe predictive coding, thus improving the compression efficiency. The magnitude of a forward motion vector, acquired through a forward motion vector search to a P-frame, is reduced in accordance with a frame distance between each B-frame and a reference frame (an I- or P-frame). The reduced forward motion vector is distributed as a forward motion vector to each of B-frames which undergoes bidirectionally motion compensation interframe predictive coding. Of B-frames, a B-frame following an I- or P-frame is subjected to a backward motion vector search while the I- or P-frame is used as a reference frame. The magnitude of the resultant backward motion vector is reduced in accordance with a frame distance between each B-frame and the reference frame (I- or P-frame). The reduced vector is distributed as a backward motion vector. Bidirectionally motion compensation interframe predictive coding is performed using the forward motion vector and the backward motion vector.

摘要： A laminate with a peelable top layer is provided. The laminate comprises a substrate such as a porous board, the top layer such as a plastic top layer or a decorated metal plate, and a bonding layer between the top layer and the substrate. At least one of the substrate and the top layer is porous. An adhesive for forming the bonding layer comprises (A) an aqueous dispersion containing a polymer, which demonstrates properties that a dried film of the aqueous dispersion has a tensile strength of 1 to 28 MPa and a percentage elongation of 100 to 2000%, and (B) a water-based adhesive composition containing microspheres with thermal expansion capability, each of which is composed of a polymer shell encapsulating a gas. By use of this adhesive, the bonding layer provides a high bonding strength between the top layer and the substrate. When irradiating the laminate with ultraviolet or far infrared, while heating, the top layer can be easily peeled off from the laminate.

摘要： In an ink jet head that reduces failure or abnormality in ink ejection, electric charge/discharge is applied between opposed electrodes and diaphragms to eject ink droplets from ink nozzles. Each of the opposed electrodes includes a main electrode and a sub-electrode formed on the nozzle side and in common with sub-electrodes for the other diaphragms. Auxiliary electric charge is applied between the sub-electrode and the diaphragms so that the menisci or ink in the ink nozzles vibrate without ejecting unnecessary ink droplets and to shorten the time for tail portions of ejected ink columns to leave the ink nozzles. Ink in ink channels is diffused so that the ink viscosity does not increase due to evaporation of ink solvent. Also, the menisci in the nozzles are drawn into the ink chambers so that unnecessary ink droplets are not ejected immediately after printing ink droplets are ejected.

摘要： A drive method of an ink-jet head is provided in which a diaphragm is deformed by means of electrostatic force to eject an ink droplet from a nozzle so as to prevent a residual charge from being created between a diaphragm and an individual electrode. The method has first and second drive modes. In a first drive mode a voltage of a first polarity is applied between a diaphragm of the inkjet head (common electrode) and an individual electrode to cause the diaphragm to be deformed and an ink droplet to be ejected from a nozzle. In the second drive mode a voltage of a second polarity opposite to the first polarity is applied between the diaphragm and the individual electrode to cause the diaphragm to be deformed and an ink droplet to be ejected from the nozzle at least once for each operation of ink droplet ejection performed in the first drive mode. According to this method, a residual charge created between the diaphragm and the electrode can be removed concurrently with performing the operation of ink droplet ejection by applying positive and negative drive voltage pulses.
