Title: Disk rotation servo circuit
Inventor: SUZUKI MASAO
IPC: G11B19/247
Filed: 1990-03-22
Abstract: PURPOSE:To improve responsiveness by superposing an acceleration pulse or a deceleration pulse on a rotational speed error signal on the way of track jump at the time of the high-speed reproducing mode where track jump and reproducing are repeated. CONSTITUTION:The circuit which controls the rotational speed of a motor which rotates and drives a recording disk of fixed linear speed is provided with an acceleration/deceleration pulse generating circuit 30, and the acceleration/ deceleration pulse from this circuit 30 is added by an inverting amplifier 16. This circuit 30 outputs the acceleration/deceleration pulse in accordance with the jump direction just after or simultaneously with track jump at the time of the high-speed reproducing mode where track jump and reproducing are repeated. The deceleration pulse is superposed on the error signal at the time of forward jump, and the acceleration pulse is superposed on the error signal at the time of reverse jump. Thus, the disturbance of error after track jump is suppressed, and the time for convergence to the steady error state is shortened to improve the responsiveness.

Abstract: PROBLEM TO BE SOLVED: To efficiently and stably obtain a yarn prepreg with a solvent-free resin deposited thereon at a specified coverage by bringing a fiber bundle into contact with a groove section on the downstream side of a rotating direction to impregnate the fiber bundle with the resin while feeding a molten resin into a groove section of a grooved roller being rotated. SOLUTION: The viscosity of the molten resin is brought to 1 to 200P. Prior to the contact of the fiber bundle with the molten resin, the fiber bundle is spread while heating the fiber bundle at a temp. above the temp. of the molten resin. After the fiber bundle is impregnated with the resin, it is brought into contact with one or more heating rollers being rotated. After the resin impregnation, the temp. of the impregnated fiber bundle immediately before winding around a core material is regulated to 0 to 35 deg.C. The yarn prepreg is wound around surface of the core material at a twill angle of 2 to 40 deg.. The drawing shows an embodiment of the apparatus for preparing a yarn prepreg. A continuos fiber bundle 2 is drawn out from a creel 1, passed through a grooved roller 3 and a drive station 8, and wound on a winder 9.

CONSTITUTION:Rotary disks 7, 8 rotate by the rotation of a rotation axis, and when a cylindrical body 1a enters in the circumferential track, a division-sealed part 1b on the cylindrical body 1a is pinched by mutual pressing parts 41a, 42a. For a period until the next division- sealed part 1b is pinched, both side surfaces of the cylindrical body 1a is press-formed by a pressing protruding surface 21a and a protruding surface 31a of a rotary gear 31. While keeping this condition, the cylindrical body 1a is transferred on the circumferential track. After that, a cam surface 13a of an external cam 13 expands, and a pinching arm 42 on the outside is detached from the container, and the container is transferred to a cutting separating process D. The outside pinching arm 42 which has been detached from the container moves in such a manner to avoid the cutting separating mechanism by the groove shape of a cam groove on a first fixing drum cam. After passing the transfer passage of the cylindrical body 1a, the outside pinching arm 42 moves to a position again where to face with a pinching arm 41 on the inside and performs a division-sealing of the cylindrical body 1a.
