Title: Oscillating circuit
Inventor: KOUNO HIROMO
IPC: H03K3/0231
Filed: 1982-05-12
Abstract: PURPOSE:To eliminate the influence of a power source and temperature and to stabilize oscillation by providing differential amplifiers which compare the potential of a capacitor with a reference potential, differential switches which switch the charging and discharging of the capacitor by its comparison output, and differential switches which switch the reference potential. CONSTITUTION:The 1st differential switches Q1 and Q2, and the 2nd differential switches Q3 and Q4 operate so that while the transistor Q1 turns on, the TRQ3 turns on, so while the capacitor C is discharged, differential amplifiers Q5 and Q6 compare a low-level reference potential (1st potential) with the capacitor potential and maintain that while the capacitor potential is greater than the 1st potential. When the capacitor potential becomes lower than the 1st potential, the 1st and the 2nd differential switches are inverted to charge the capacitor while raising the reference potential up to the 2nd potential, thereby maintaining this state, until the capacitor potential rises up to the 2nd potential. Then, the gains of the differential amplifiers are increased to reduce the offset potentials of the switches.

Filed: 1989-03-30
Abstract: PURPOSE:To reduce recording/reproducing errors, and to prevent component damage at the time of carriage by providing a vibration absorbing means on the upper part of an optical head with the use of separate damper and a cover with necessary mass, and composing a motion vitrasion absorbing device of them. CONSTITUTION:Dampers (A) 12 are attached to the four corners of a frame 11, and their width is set so that the frame may not make contact with a drive main body 13. An insulating damper (B) 14 is mounted on the main body 13. The damper is a rubber vibration insulator with a suitable spring constant and a viscous extinction coefficient. A cover 15 has the necessary mass, and plays the role of an electromagnetic shield. A sub-vibrating system m2-k2-C is added to a main vibrating system m1-k1, which receives exciting force at a random frequency from the outside to the moving vibration absorbing device with mass (m), a spring constant (k), and a viscous extinction coefficient C, and the vibration of the main vibrating system is transferred through a spring k2 and a damper C to the sub-vibrating system. When a coefficient C is suitably fixed, only the sub-vibrating system is made to resonate, and m1 can approach standstill. Consequently the recording/reproducing errors can be reduced, and the component damage due to an impact during carriage hardly occurs.
