Title: Disk device
Inventor: KATO KAZUNARI
IPC: G11B17/30
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To provide a disk device capable of operating a rotating means driving different disks and a thread mechanism moving a head with the minimum number of motor. SOLUTION: A first rotating means having a turntable 42, a second rotating means having a clamp table 44 and the thread mechanism 50 moving an optical head 46 by a screw shaft 49 are mounted on a drive base 10. When a CD is clamped to the turntable 42, torque of the clamp table 44 is transmitted to the thread mechanism 50 by a second interrupting means 67 to move the optical head 46. When an MD is clamped to the clamp table 44, the torque of the turntable 42 is transmitted to the thread mechanism 50 by a first interrupting means 53 to move the optical head 46. Thus, a motor used exclusively for the thread mechanism 50 is eliminated.

Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To provide possibility of exact coincidence of an engine rotational speed with the target rotational speed without making feed-back of a throttle valve opening detection valve during idle operation of an engine by using a skewed electric motor as an electric motor for driving the throttle valve. SOLUTION: A micro-computer 1 outputs a command value based on a deviation between the target rotational speed and an engine rotational speed during idle operation of an engine. This command value is supplied to PWM circuit 5 after being converted to an analog signal by means of a rudder resistance 2. The PWM circuit 5 compares the command value with saw-wave or triangular wave, etc., transmitted from a wave form generator 4 and supplied a positive polar PWM signal and a negative polar PWM signal of a duty ratio corresponding to the command value to the gates of bridge-connected electric field effect transistors 6 to 9. Thereby, a skewed electric motor 10 is controlled in its rotational direction and driving current in response to a ratio of a positive directional current CW to a reverse direction current CCW.  Accordingly, the opening of a throttle valve is so controlled as making an engine rotational speed to accurately coincide with the target rotational speed during idle operation.
