Abstract: PURPOSE:To improve an error rate by outputting the information without generating an error out of respective pieces of information decoded by first and second decoders. CONSTITUTION:A digital signal reproduced by one rotation of a rotating cylinder 1 by an A head 2 and a B head 3 for recording and reproducing is amplified by a first amplifier 15, error-corrected/detected by a first decoder 16 and decoded to the data. On the other hand, a signal reproduced by an A' head 4 and a B' head 5 for reproduction of the 90 deg. delaying from an A head and a B head 3 is amplified by a second amplifier 19, error-corrected/detected by a second decoder 20 and decoded to the data. The same track is reproduced two times, the error-correcting/detecting is executed concerning respective reproducing signals, the generating condition of the error is compared for respective pieces of the information and the information without the generation of the error is outputted. Thus, an error rate can be improved and the erroneous correction, which cannot be detected conventionally, can be detected.

Title: Optical disc device
Inventor: KUWAYAMA YASUNORI
IPC: G11B21/12
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To provide an optical disc device which enables restoration when an optical pickup is disengaged from a lead screw. SOLUTION: For example, in the case where a lead screw 14 does not rotated even when a driving voltage is applied to a thread motor 16, it is determined that a screw guide 12a is disengaged from a screw groove 14a (run-upon state). When the run-upon state is detected, driving of the thread motor 16 is temporarily stopped and a microcomputer 18 determines the direction of movement of an optical pickup 12 in accordance with the output (on/off) of a switch 26. Then, the microcomputer 18 instructs a DSP 20 so that the thread motor 16 rotates in the predetermined direction of movement at a driving voltage five times the normal driving voltage. Therefore, the lead screw 14 is rotated over a frictional force generated between the screw guide 12a and the surface of the lead screw 14, and the state in which the screw guide 12a is engaged with the screw groove 14a (normal state) is restored.  Thus, the normal state can be restored from the run-upon state.

Title: Planographic printing plate
Inventor: NISHIWAKI FUMITOSHI
IPC: B41N1/08
Filed: 1987-12-10
Abstract: PURPOSE:To uniformize the film thickness distribution of the ink to be printed over the entire surface of the film so that the printing distinctly delineating the boundary face between the ink and a circuit board to be printed is executed by forming ink absorbency layers on the side wall surfaces of the dents in an image part. CONSTITUTION:The photosensitive resin layers 18 having an ink-philic property are formed on the side wall surfaces 17 of the dents 14 in the image part 16. The ink 19 is, therefore, prevented from being repulsed by the side wall surfaces 17 of the dents 14 and is filled in the dents 14 at nearly a uniform thickness when the ink is transferred to the plate surface. The formation of the printing pattern to the small ink film thickness in the end part of the ink films of said patterns as in the conventional practice is consequently obviated when the circuit board 20 to be printed is subjected to printing by using the plate. The film thickness distribution of the ink is thereby uniformized over the entire printing surface and the printing delineating the distinct boundary face between the ink film and the circuit board is executed.
