An ink-jet head includes a channel unit which includes a plurality of pressure chambers, a vibration plate stacked on the channel unit, and a piezoelectric material layer arranged on the vibration plate. The piezoelectric material layer includes a first portion functioning as a piezoelectric actuator, and a second portion functioning as a piezoelectric transformer which amplifies a driving signal to be supplied to the piezoelectric actuator. Accordingly, it is possible to realize a small-size ink-jet head with a built-in piezoelectric amplifier.

Ultra-fine particles are jetted from a nozzle to be deposited on a substrate via a mask which is plate-shaped and in which an opening pattern is formed, thereby forming on the substrate a thin film having a shape corresponding to the opening pattern. The mask has a first area, a second area which surrounds the first area and defines an opening between the first area and the second area, and a bridge portion connecting the first and second areas. The bridge portion is formed at a position away from the bottom surface of the mask. By using this mask, a thin film having a pattern including an independent non-film formation area can be formed.

A magnetic sensor including a ferromagnetic tunnel junction, comprises a free layer 10 a magnetic direction of which freely rotates, and a barrier layer 11 formed on the free layer and reduces a thickness in a first region, the free layer in a region corresponding to the first region functioning as a sensor portion for sensing an external magnetic field. Such magnetic sensor can provide magnetic sensors, magnetic heads and magnetic encoders having high sensitivity. Furthermore, such magnetic sensor can provide magnetic heads which are adaptable to high recording density of magnetic storage mediums, and hard disk devices of large storage capacities using the magnetic heads.

A non-contact type hydrostatic linear guide device includes a guide unit having a pair of rail parts on the top surface thereof, and a slide unit having oil pockets in a running surface thereof. A load of the slide unit concentrates on the frame of the guide unit. The slide unit has a stepped leg structure in which projections are disposed in the under surface of a table thereof in bilateral symmetry. The projections contact the top surface of inner projections disposed on the guide unit and the outer side surfaces thereof face the inner surfaces of the wear plates disposed on the guide unit, and wear plates are placed outward in the midway of the under surfaces of the projections as the side surfaces thereof face the both side surfaces of the first recessed part and the third recessed part of the guide unit.

A display driver capable of operating in any one of multiple gradient display modes drives a liquid crystal panel in which the first L common electrodes are simultaneously selected in a first selection period and successive groups of L common electrodes are simultaneously selected in successive selection periods. 8-bit display data for each segment electrode are simultaneously read from a display data RAM and latched. First and second sub-decoders decode divided upper and lower four bits of the 8-bit display data, respectively. In a first mode, the data is for a four gradient display for each of four pixels on each segment electrode. In a second mode, the data is for a two gradient display for each of eight pixels on each segment electrode.
