Title: Bicycle
Inventor: YOON YOUNG JAI
IPC: B62J1/10
Filed: 1999-04-03
Abstract: PURPOSE: A bicycle is provided to reduce the force needed in driving a pedal by lengthening a distance up to a pedal from a pedal drive shaft. CONSTITUTION: Upon the pedal rolling action of a right pedal arm tool, a pedal rolling force of a left pedal arm tool is removed. The left pedal arm tool is automatically returned to an upper limit position by the elastic restorative force of a coil spring. Thus, right/left pedal drive shafts(11) rotate alternately by a certain angle by rolling the right/left pedal arm tools in turns. The rotational force is transferred to an input shaft(36) by a power transfer device(33) in order so that the input shaft continuously rotates. Herein, since the distance from a pedal to the pedal drive shaft is long, a small force is needed in rolling the pedal arm tool.

Abstract: PURPOSE: A high speed data access device for an optical disc, and a method therefor are provided so that an access speed can be increased and stabilized in reproduction of the optical disc. CONSTITUTION: A high speed data access device for an optical disc consists of a read unit, a transfer unit, a data processing unit and a control unit. Here, a reproduction speed of an object position of an optical pickup is calculated according to a current reproduction speed of the optical disc. A data read clock is varied correspondingly to the calculated reproduction speed. Thereafter, a recorded data is read and reproduced in the position according to the varied data read clock. That is, the data read clock is varied before the optical pickup moves to the object position, and thus more rapidly stably phase-synchronized with the reproduction clock. Accordingly, as soon as the optical pickup moves to the object position, the recorded signal on the optical disc is detected and restored. As a result, the access speed can be increased and stabilized. In addition, an access time can be decreased.
