Title: Rotation control system for recording disk
Inventor: NAITOU RIYUUICHI
IPC: G11B19/20
Filed: 1981-05-27
Abstract: PURPOSE:To prevent a runaway of a spindle servo system for a CLV disk by driving a motor at a constant voltage when the PLL of the spindle servo system after the ending of the searching operation of a pickup is not locked. CONSTITUTION:If none of PLLs 206, 207 and 208 is locked after the fast-forwarding operation of a pickup 203 ends (when a playback signal is disordered temporarily by external intense oscillation after the start of the fast-forwarding operation), the output of a lock detecting circuit 209 for the PLLs is h, and a control circuit 215 holds a switch control signal (k) to (L) and a sweep signal (j) to (H). Therefore, a switch 213 is changed over to the side of a prescribed voltage (f) to drive a motor 202 in a certain state, preventing a runaway. A sweeping circuit 210 allows a VCO208 to start sweeping operation and the PLLs enter into a lock-in state again a certain time later. Consequently, the output of the control circuit 215 is inverted to obtain a stationary servo state.

Filed: 1982-05-14
Abstract: PURPOSE:To obtain a drift-free absolute speed signal which has less phase lag and less noise by inputting the signal of a speed sensor to a negative feedback loop consisting of an inertia sensor, an integrator, and a low-pass filter. CONSTITUTION:The low-pass filter 3 consists of a primary low-pass filter 6, integrator 7, and adder 8. The detection signal S1 from the speed sensor is subtracted from the output signal S2 of the integrator 2 by a subtracter 5 to obtain a signal S3, which is inputted to the primary low-pass filter 6 to filter its high frequency component. The output signal of the primary low-pass filter 6 is divided into two; one signal component is added by an adder 8 after the time integration of the integrator 7 to the other component to obtain a signal S4. A subtracter 4 subtracts the output S4 of the low-pass filter from the acceleration signal S5 of the inertia sensor to obtain a difference signal S6 which is time-integrated by the integrator 2 to obtain an output signal S2.

Title: Detection system for channel fault
Inventor: SATOU TAKAAKI
IPC: H04M3/22
Filed: 1980-06-16
Abstract: PURPOSE:To detect a faulty path without exerting any evil influence on normal incoming and outgoting line connections, by determining a suspicious group of paths when a fault occurs, by excepting normal calling paths from the suspicious groups of paths, and by regarding the faulty path the remainder which is not excepted. CONSTITUTION:If a fault regarding calling paths is detected, path information is applied from a channel controller SPC to a generator DCPG for a suspicious group of paths. On the basis of the said path information and information on path occupation stored in a connecting path storage device CPM, the DCPG determines a suspicious group of paths and then stores it in a storage device DCPM for the suspicious group of paths. Later, normal paths which are not detected by a fault detector FD1 are applied from the SPC to a normal-path information eraser CPR and erased from the DCPM. A faulty-path discriminator FCPJ monitors the DCPM and judges the remaining path as faulty one a certain time later.
