摘要:
A multinozzle ink jet recording device having a dense arrangement and a method of producing the same are disclosed. Two electrodes for applying a voltage to the side walls of a piezoelectric plate lie in the range of a pressure chamber, so that an electric field is prevented from acting on portions which do not contribute to the ejection of an ink drop. This obviates the waste of voltage and thereby realizes low voltage drive which reduces the size of the pressure chamber. All the grooves serve as pressure chambers without any slit or similar wasteful space intervening between them. Thus the multinozzle print head has a dense configuration. With such a print head, the recording device achieves a miniature and compact arrangement.

An ink jet recording head has a plurality of ink channels, disposed on a piezoelectric substrate, for receiving liquid ink therein, a plurality of dummy channels arranged alternately with the ink channels on the substrate, a top plate for covering the ink channels and dummy channels, and a nozzle plate defining the front end of the channels and having a nozzle for each of the ink channels for ink ejection. The dummy channels have a depth larger than the depth the ink channel, and the top plate has a slit extending along each of the dummy channels, for reducing cross-talks between adjacent ink channels.

A display device reduces the image quality degradations by suppressing the effect of the defective alignment regions caused by the spacers while minimizing the aperture ratio lowering, and prevents the image quality change dependent on the observation positions. The display device has a display panel and a lenticular lens. Each unit pixel of the display panel includes the sub-pixel for the left eye and the sub-pixel for the right eye. To keep the pair of substrates at a predetermined gap, spacers are arranged at predetermined positions in the gap. The spacers are stripe-shaped and extended along a direction perpendicular to the image separation axis of the lenticular lens. The spacers are equally overlapped with the sub-pixels for the left eye and those for the right eye. The spacers may be isolated for the respective unit pixels, or the first or second sub-pixels.

A vehicle lamp device comprises a lighting chamber (14) defined by a housing (11) and a lens (12). A holding tube portion (11c) having a through hole (11b) is formed in a rear wall (11a) of the housing (11). An air pipe (15) is engaged with the holding tube portion (11c) through which the lighting chamber (14) is connected to the outside. An air hole (15c) is formed in the midway of the air pipe (15) in addition to an end opening (15a). A covering portion (11d) is formed as a holding portion in the rear wall (11a) for covering the air hole (15c) from above and for holding the air pipe (15).
