Patent JP-H0721567-A (JP)
Title: Optical disk and optical disk device
Inventor: TSUKAMURA YOSHIHIRO
IPC: G11B7/24082
Filed: 1993-06-30
Abstract: PURPOSE:To directly cancel a DC offset from a tracking error signal without generating a tracking error at the time of seeking. CONSTITUTION:A magneto-optical disk 7 is not formed with a mirror part and is continuously formed with guide grooves 31. The patterns of these guide grooves 31 are formed to a triangular waveform and are displaced by one track pitch Tp in a radial direction from a normal position in an offset detection region WD. The max. amplitude widths on the positive side and negative side of the tracking error signal Et are obtd. in the detection region WD. A difference is generated in the max. amplitude width values on the positive side and negative side if there is the DC offset in the error signal Et. The DC offset is detected by reducing this difference to a half. The DC offset is thus canceled from the error signal Et. There is no need for forming the mirror part on the disk 7. The generation of a track loss signal is not generated and the track error is not generated at the time of seeking. High-speed seeking is possible with a magneto-optical disk device.

Abstract: PURPOSE:To enable a cassette ribbon to be used for a longer period of time while maintaining a conventional length of the ribbon, by enlarging the width of a printing ribbon to enlarge the area of the ribbon, and reciprocally using the ribbon for printing through multiple zones of the ribbon. CONSTITUTION:When printing through the first zone of a printing ribbon is finished, both rotary shafts A, B (4) are simultaneously lifted up by a one-zone amount, whereby a cassette 3 and the printing ribbon 1 fitted to the shafts are also lifted up by a one- zone amount, and the second zone is raised to a printing position. Simultaneously, motor drive for the rotary shaft 4 is switched over from the shaft A to the shaft B, and the ribbon 1 is taken up rightward by the rotary shaft B (4) connected to a motor while the second zone of the ribbon 1 is struck by a head 2 according to key inputs to print on a paper. Thus, when the printing through each of the zones of the ribbon 1 is finished, the rotary shafts A, B (4) are alternatively connected to the motor automatically, and the rotary shafts 4 are simultaneously lifted up by the one-zone amount at a time so that the next zone of the ribbon 1 can be used for printing by the head 2.

Abstract: PURPOSE:To prevent a paper sheet or the like from being charged into a placement section with a pressure means left as it is on the placement section by providing the pressure means with an extension part extending over the top surface side of the placement section. CONSTITUTION:A wire 17 for weight is arranged between a kick roller 14 and a transfer roller 16 and is provided with a pressing part 18 capable of displacement to a position lower than a tangent line extending between the kick roller 14 and the transfer roller 16, and with an extension part 19 extending from the pressing part 18 to the top surface side of a placement section 4. After the placement section 4 is emptied, paper sheets or the like (a) are stacked again in tiers on the placement section 4. At this time, an extension part 19 of the weighting wire 17 projects to face the placement section 4. As a result, if throwing of the paper sheet or the like (a) into the placement section 4 is attempted while failing to retract the weighting wire 17 from the placement section, the extension part 19 of the weighting wire 17 hinders the charging. As a result, incorrect charging is prevented.

Abstract: PURPOSE:To generate a large beating noise in a proper interruption cycle by controlling the electric charge and discharge of a timer circuit in another system, according to the variation of the potential in a series circuit of a direction indication lamp, selecting switch, and an interruption switch. CONSTITUTION:When the movable contact point SM of a selecting switch SW contacts a fixed contact point SR, the Potential at the connection point between resistors R3 and R5 lowers, and at the completion of charge of a capacitor C1, an transistor Q2 is turned ON. Then, Q1 is turned ON, and a relay RY is excited to close a beating noise generating relay switch ry, and lamps L1 and L2 light up. At the same time, C2is charged, and if Q2 is turned OFF at the time point when charging operation considerably proceeds, also Q1 is turned OFF, and RY is deenergized, and lamps light OFF. C2 is electric-discharged by the turning-OFF of Q1, and in the process of the electric discharge, Q2 is turned ON again, and lamps light up again. At this time, a large beating sound is generated in the switch ry.
