Title: Bar code reader
Inventor: OKAMOTO AKITO
IPC: G06K7/10
Filed: 1992-02-14
Abstract: PURPOSE:To provide a bar code reader capable of accurately reading out any bar code only by the reader itself independently of a distance up to a bar code to be read out. CONSTITUTION:A distance from the set position of the reader up to a bar code to be read out is detected by a range finder 11.

Abstract: PURPOSE:To enhance mechanization to eliminate sediment, improve the efficiency of a boiler and enhance a utilization factor of an entire device by mounting a cutter assembly designed to remove sediment at the tip of a piston rod which makes a reciprocating motion with compressed air and eliminate the sediment in an air supply port with a cutter. CONSTITUTION:A solenoid valve 8 is manipulated so that compressed air may be supplied into a cylinder tube 2 from a head side air port 6, thereby driving a piston 1 in the direction marked with A. The air on a piston rod side is exhausted to an exhaust port of the solenoid valve 8 from a piston of a side air port 7 at that time. A piston rod 3 is also arranged to move in the direction of A and forces a cutter assembly 10 to thrust into an air supply port 11, thereby cutting off the sediment in the air supply port 11. An attempt is made to shift air supply so that the cutter assembly and the piston rod may go back. This construction makes it possible to eliminate the sediment more efficiently and improve the utilization factor of the entire device.

The entire surface is thereafter subjected to the mechanochemical polishing to <=30Angstrom  surface roughness. A main magnetic pole 7 and thick-film main magnetic pole 8 consisting of amorphous Co are then sputtered and a protective film 9 consisting of Al2O3 is deposited thereon. Edge rising of the path part 6 is thus eliminated and the thin film head having high efficiency and excellent magnetic characteristics is obtd.

Filed: 1988-02-12
Abstract: PURPOSE:To shorten time necessary for initializing by enlarging the beam spot of an Argon laser uniformly along a magnetic field impressing means by a combined concave lens and projecting the beam spot on plural tracks simultaneously. CONSTITUTION:A magneto-optical disk 1 is rotated by a rotating means 2 and a magnetic field HH is impressed by a magnetic field impressing means 3 composed of a permanent magnet, etc., facing to a face 13.
