Title: Laser beam synthesizing device
Inventor: TATENO KIMIO
IPC: G11B7/125
Filed: 1983-12-14
Abstract: PURPOSE:To synthesize plural laser beams to one beam without being influenced by a disturbance, by detecting optically a beam position shift, driving an actuator, and moving a lens or a laser. CONSTITUTION:Coupling lenses 13, 14 for collecting beams from semiconductor lasers 9, 10 are held by actuators 15, 16, respectively. When the laser 9 is shifted by a disturbance, two spots on a reference plate 21 move, a light quantity which is reflected and returned to a lens 23 is varied, an unbalance is generated in a light quantity of photodetectors 24, 24', and a difference is generated in an output current between opposed segments, therefore, this difference is detected and fed back to the actuator 15 as a spot shift detecting signal, and the center spot on the reference plate 21 is collected to the cross point. Accordingly, even if a position shift is generated in two condensing spots on a recording surface 12 by a disturbance, the lenses 13, 14 are moved on the surface vertical to the optical axis by an operation of the actuators 15, 16, and the two condensing spots can be adjusted so that there is no position shift.

Title: Pit length adjusting device, optical disk master disk exposure device and optical disk driving device
Inventor: NAOE HITOSHI
IPC: G11B7/125
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To simply form a pit where a regenerative waveform of a recorded pit is adjusted to an optimum length by individually adjusting front edge part and rear edge part of a recorded pulse without changing a recording position. SOLUTION: A first pulse Pi is obtained by delaying a prescribed pulse P with a first delay circuit 1 of a delay amount of an integer number (n) ×minimum resolution At, and a second pulse P2 is obtained by delaying the pulse P with a second delay circuit 2 of the delay amount of a reciprocal T of a recording frequency + the integer number (m) × Δt. Then, a third pulse P3 is generated by ADNDing both pulses with an AND circuit 3, and a fourth pulse P4 is generated by ORing both pulses with an OR circuit 4. Since the third, fourth pulses P3, P4 are pulse width corrected for a zero pulse PO delayed by the reciprocal T from the prescribed pulse P, pit length correction becomes possible without changing a pit central position even when a correction value is changed for a continuous pit.  Thus, the third pulse P3 of a short pulse width for a high sensitive optical disk, and the fourth pulse P4 of a long pulse width for a low sensitive optical disk are inputted, and the length of the pit is adjusted.

Abstract: PURPOSE:To produce a woven fabric free from steps between the beam warps in lateral direction by using a plurality of independently driven warp-delivery beams, connecting one beam to an electric delivery device an the other beam to a synchronizing control apparatus to rotate the beam at a specific ratio. CONSTITUTION:A pair of warp-delivery beams are arranged in the lateral direction of a loom and driven by independent delivery motors. A warp-delivery beam relating to a delivery motor is rotated at a target warp tension by a tension controller.
