Title: Information reproducing device
Inventor: IMADA YOSHINOBU
IPC: G11B19/247
Filed: 1988-04-15
Abstract: PURPOSE:To improve the random access speed in a disk device having a constant linear speed by setting the r.p.m. of a disk motor corresponding to a target access track and performing a coarse control to conform a regenerative demodulation synchronizing signal and a reference time signal in width. CONSTITUTION:A switch 11 is connected to a contact point B, and the disk motor 1 is set at the r.p.m. corresponding to a target track by a prescribed r.p.m. setting circuit 6. Then, the width of the regenerative demodulation synchronizing signal from a demodulation circuit 8 is compared with the width of the reference time signal corresponding to the settlement from a reference time generator 10, so as to perform a coarse control on a motor 2 for moving a pickup 3 to make an output of a comparator circuit 9 zero. After this coarse control is finished, the contact point of the switch 11 is changed over to A, and a fine control is performed on the motor 1 by a servo control which is not capable of corresponding to a large fluctuation via a disk motor servo circuit 5. By this method, the random access time is reduced, while the random access speed is promoted.

This sludge flows out automatically to a sludge storage part 12, and is concd. to a required concn. by gravity, after which it is discharged through a sludge discharge port 6. The waste water removed of sludge in the part 11 flows out as treated water through an overflow port 5.

Title: Amplifier
Inventor: ITOU YASUHIRO
IPC: H03F1/42
Filed: 1978-07-29
Abstract: PURPOSE:To prevent the reduction of the input impedance for the noninverse input terminal by inserting the 1st and 2nd diodes which are connected in opposite polarity to each other between the noninverse terminal and the output terminal of the operational amplifier, and thus to secure protection to the overinput with a simple circuit. CONSTITUTION:The signals supplied from signal input terminal 5 are supplied to the noninverse input terminal of operational amplifier 4 via input resistance 1, and the output of amplifier 4 is applied to the inverse input terminal of amplifier 4 as well as to output terminal 6. Then 1st and 2nd diodes 2 and 3 connected to each other in the opposite polarity are inserted between the noninverse input terminal and terminal 6 of amplifier 4, and the overlap voltage is made identical between diodes 2 and 3. Thus the voltage application is avoided to diode 3, and the signal applied to input terminal 5 is delivered to terminal 6 with no effect of diodes 2 and 3. In case the overinput is applied, the voltage of the noninverse input terminal of amplifier 4 is set lower than the voltage obtained by applying the forward voltage of diodes 2 and 3 to the saturation voltage to secure the protection to the overinput.
