摘要： An image formation apparatus includes a first discharge unit to form an image on a recording medium; and a second discharge unit including a nozzle line that discharges transparent droplets on the image formed on the recording medium. The second discharge unit moves in a first direction relative to the recording medium and the nozzle line has nozzles in a second direction orthogonal to the first direction. After the image formation, the second discharge unit discharges the transparent droplets from the nozzles spaced at m−1 nozzle intervals to form a row of dots in the second direction, and repeats the forming while moving to form m rows in the first direction, such that the dots in the rows are formed at m−1 nozzle intervals and positions of the dots between n-th and n−1-th rows are displaced together by one nozzle in the second direction.

摘要： A scroll compressor providing a ring-shaped groove in an end plate of a movable scroll to form a backpressure chamber with a surface of a middle housing supporting the end plate and introducing a high-pressure fluid through the same so as to cancel out a thrust load generated by the compression reaction force. Inner and outer seal rings are provided to prevent leakage of the high-pressure fluid from the backpressure chamber. In this case, the seal rings are designed to be able to incline in the ring-shaped groove or O-rings are made joint use of to form a ring-shaped region of a higher contact pressure at a portion contacting the opposing surface, so a high sealing effect is obtained while suppressing mechanical loss.

摘要： An ink jet printhead composed of: a reservoir storing a quantity of printing ink, an ink manifold defining an ink supply volume in communication with the reservoir for holding a supply of ink received from the reservoir and a plurality of individually controlled ink jet delivery channels, each of the channels having an ink drop ejection transducer and an orifice to eject successive ink drops on demand in response to pressure pulses produced by the transducer, and each of the channels being in communication with the ink supply volume for receiving ink from the ink supply volume. The manifold is constructed to give the ink supply volume a large acoustic compliance to minimize propagation of pressure disturbances in the ink supply volume and acoustic signal crosstalk between the channels.

摘要： To increase the size of dot printed on a print medium with an on-demand multi-nozzle ink jet head, at least two unit pulses are applied in succession to a piezoelectric element which varies the volume of an ink chamber. The unit pulse has a pulse width substantially equal to a period of Helmholtz natural oscillation determined based on dimensions, materials, and physical properties of an ink channel and the piezoelectric element and other components relating to oscillation. An off duration between adjacent unit pulses applied in succession to the piezoelectric element is preferably set one fifth to one fourth of the unit pulse width.
