Filed: 2001-01-29
Abstract: PROBLEM TO BE SOLVED: To perform correction of rotation drive control for each bobbin holder independently when moving from a contactless winding process to a normal winding process in a thread winding device having multiple bobbin holders. SOLUTION: When carrying out contactless winding, wherein a contact roller CR is held to be not in contact with a bobbin B, or soft winding, wherein a contact roller CR is held with a low contact pressure, the rotation drive of the bobbin holder is generally expectedly controlled based on a formula. The formula is, in this invention, is corrected for each bobbin holder independently. Accordingly, optimum correction is provided for each bobbin holder even when there is difference in slip of the motor, and therefore high-accuracy correction can be realized and generation of defective threads can be prevented.  By using a correction value obtained from the winding process of a first bobbin holder for the second contactless winding process or the soft winding process of a second bobbin holder, speed variation can be suppressed even when initial parameter setting values are somewhat inappropriate.

Title: Semiconductor laser driving circuit
Inventor: YUWAKI TAKESHI
IPC: B41J2/44
Filed: 2001-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser driving circuit which can drive a semiconductor laser at a high speed by using a semiconductor integrated circuit to which a withstand voltage margin is set and which has a superior high-frequency characteristic and a fined structure. SOLUTION: Since an idling current is always made to flow to the semiconductor laser LD1 and a band-gap voltage Vb is always set to the laser LD1 while the laser LD1 is in a nonoperating state by means of a simple constitution based on a resistor 10a connected between the cathode and earth of the laser LD1, no power-supply voltage Vcc is applied across the collector and emitter of a transistor Tr1, and a withstand voltage margin equal to the band-gap voltage Vb (Vb=Vcc-Vc) is set to the transistor Tr1. Consequently, it becomes possible to use the semiconductor integrated circuit having the superior high-frequency characteristic and fined structure by relieving a withstand voltage condition by the amount of the set withstand voltage margin and high-density recording can be performed on, for example, an optical disk by causing the laser LD1 to radiate short-wavelength laser light.
