An ink jet recording head unit includes a plurality of nozzle elements, a plurality of piezoelectric elements and a driving unit. The plurality of piezoelectric elements is provided in one-to-one correspondence with the plurality of nozzle elements. Each piezoelectric element has a positive pole and a negative pole. Each piezoelectric element expands and contracts when a voltage potential difference between the positive pole and the negative pole is varied. The plurality of nozzle elements includes a first nozzle element and a second nozzle element adjacent to the first nozzle element. A first piezoelectric element and a second piezoelectric element correspond to the first nozzle element and the second nozzle element respectively. The driving unit controls the first piezoelectric element and the second piezoelectric element to expand and contract in a complementary manner.

In an inkjet device that ejects ink on a medium with an inkjet head, data conversion software generates ejection data and timing control data from pattern data that describe patterns of ejection target pixels. A timing control board outputs a drive waveform generation trigger signal and a data transfer request signal to a drive waveform generator board and a memory board, respectively. The drive waveform generator board generates drive waveforms according to drive waveform generation trigger signal. The memory board transfers ejection data to the driver board according to the data transfer request signal. The driver board controls ink ejection of each nozzle based on the ejection data. Therefore, the inkjet device is capable of highly accurate positioning of ink ejection with almost no increase in the amount of data.

A structure for mounting a vehicle seat includes: a side sill extending in a front-rear direction of a vehicle body on a side of the vehicle body; a cross member extending in a width direction of the vehicle body; a floor frame substantially extending in a front-rear direction of the vehicle body, with an end portion curved and joined to the side sill, and thus bridging the side sill and the cross member; a seat-mounting bracket joined to the floor frame; and a seat fixed at least to the seat-mounting bracket. With this structure, the seat can be securely fixed to the vehicle body.

The present invention provides a highly convenient removable device and a startup method. A hub division unit 31 in a single composite device 2 allocates data exchange with the computer 1 side to a plurality of devices, thereby easily realizing a plurality of functions. When connected to a USB, a recognition control unit 32 returns a signal representing a CD-ROM in a simulated manner in response to inquiry about the type of the device from the host side. When a device is mounted, a desired processing such as a program execution described in the script is automatically performed without installing a resident program for detecting a device mounting in advance in the computer side.

An inkjet recording device includes a nozzle module, a switching unit, a waveform generating unit, an image recognizing unit and a pulse width modulating unit. The image recognizing unit determines an ejection condition of the ink droplet ejected from the nozzle while referring to ejection data indicating a type of each pixel to be recorded, and generates switch pulse width data that includes the ejection data and the ejection condition. The pulse width modulating unit generates the switch pulse based on the switch pulse width data. The switching unit opens and closes in response to a switch pulse. An opening duration of the switch unit is variable depending on the switch pulse.

A sheet-position synchronizing signal is generated once each time a recording sheet is transported by a single-line worth of distance in a sheet feed direction. A print-driving signal and a refresh-driving signal are generated within a time interval of two successive sheet-position synchronizing signal. When the print-driving signal is applied to a piezoelectric element of a nozzle, then a print ink droplet is ejected, thereby a dot is formed on a recording sheet. On the other hand, when the refresh-driving signal is applied to the piezoelectric element, then a negatively-charged refreshing ink droplet is ejected. The refresh ink droplet refreshing ink droplet is deflected by an electric field and collected by a metal mesh without reaching the recording sheet.

An electrode plate includes a base electrode plate, an edge forming electrode plate on the base electrode plate, and an ink reception absorption bodies embedded into the edge forming electrode plate. A plurality of head modules are precisely attached to the electrode plate so that nozzle rows formed in nozzle plates of the head modules extend following corresponding windows formed in the electrode plate. Such a precise attachment is realized by matching the pinholes formed in the nozzle plates to the corresponding pinholes formed in the base electrode plate and the edge-forming electrode plate.
