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： 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： An apparatus is provided for ejecting liquid drops while eliminating a special sensor (a photosensor) and improve detection accuracy for abnormal ink drop ejection. When the detecting an abnormal ink drop ejection, a drive circuit outputs an actuator-driving voltage in addition to an original drive voltage with a contact of a changeover switch located in a first position. The original drive voltage causes the electrostatic actuator to be driven. Thus, the vibrating plate is vibrated, whereby ink drops are ejected. Thereafter, the electrostatic actuator is charged with a charge according to the actuator-driving voltage. The charging voltage corresponds to the residual vibration of the vibrating plate. Then, the contact of the changeover switch is switched to a residual vibration-detecting circuit. Thus, the residual vibration-detecting circuit is supplied with the charging voltage to thereby output a residual vibration waveform.

摘要： A high-speed motion retrieval device is provided that certainly unerring motion vector at high speed. The first-stage motion retrieval means 12 retrieves a retrieval range determined by referring to the retrieval result in the previous frame. If a minimum predictive error is smaller than a threshold value, the motion retrieval process is ended at the time the retrieval range has been retrieved. If the minimum predictive error is larger than the threshold value, the second-stage motion retrieval means 13 retrieves the region which has not been retrieved through the first-stage motion retrieval within a predetermined retrieval range, thus obtaining the location with a minimum predictive error. Thus, the retrieval is divided into two steps. Motion vectors can be retrieved with small error detection and at high speed by suitably changing the first-stage retrieval range.
