The present invention relates to an ink jet printer in which drops of ink are jetted out onto a surface of a recording medium so as to record an image. The present invention is to obtain an economical ink jet printer in which a reaction force generated in the reciprocal motion of the ink jet head is simply canceled, and the ink jet printer is small and light, and less vibration is caused in the printer, and further it is possible to drive the printer with a small amount of drive energy. The ink jet printer includes: a recording medium conveyance device for conveying a recording medium in the subsidiary direction; a plurality of ink jet heads in which a plurality of nozzles for jetting drops of ink to a surface of the recording medium are disposed, the ink jet heads being capable of moving in the primary scanning direction substantially perpendicular to the subsidiary scanning direction, the ink jet heads being arranged in the printer main body being aligned in the subsidiary scanning direction; and a head reciprocation drive device for reciprocating the ink jet heads in the primary scanning direction at phases different from each other.

A magnetic disk drive has a magnetic disk and a magnetic head assembly mounted on an arm. The assembly is utilized in the recording and reproducing of data on and from a recording/reproducing surface of a magnetic disk. The magnetic head assembly includes a support body for connecting the magnetic head assembly to the arm and a head chip attached to the support body. The head chip is configured and arranged for making substantially continuous sliding contact with the recording/reproducing surface of the magnetic disk during recording/reproducing. The head chip includes a wafer base, a read/write element for recording/reproducing data from the recording/reproducing surface of the magnetic disk. The read/write element is formed from a plurality of thin film layers superposed upon the wafer base and the head is elongated in a direction generally perpendicular to a plane generally defined by the recording/reproducing surface.

A gas reactor includes a dielectric casing made of a dielectric material and forming a first conduit for directing first gas in one direction, a first electrode positioned inside the dielectric casing along a general center thereof and extending in the direction, at least one catalyst layer formed on a surface of the first electrode, and a second electrode surrounding an outer wall of the dielectric casing. The gas reactor further includes a power-supply unit applying AC power between the first electrode and the second electrode to generate glow discharge inside the dielectric casing.

There is provided an ultrasonic printer in which convergent ultrasounds are radiated to emit an ink near a convergent point of the convergent ultrasounds in the form of an ink droplet and deposit the ink droplet on a recording medium such as a paper sheet, thereby performing a recording on the recording medium with multiple ink dots, with higher resolution. The ultrasonic printer has a plurality of ultrasonic transducers which transmit phase-controlled ultrasonic waves to form an convergent ultrasonic acoustic beam.
