Title: Phase synchronizing circuit
Inventor: UCHIKOSHI KOUJI
IPC: H03L7/08
Filed: 1981-07-03
Abstract: PURPOSE:To increase a frequency leading-in range by providing a means which discriminates whether a phase state is within a normal lock-in range on synchronization or not, and a storage means for the phase states of an input and an output signal in a sychronous state. CONSTITUTION:The detecting circuit consisting of a fine delay circuit 6 and an EXOR7 detects the variation point of an input NRZ signal to trigger a monostable multivibrator (MM)2. The MM2 generates pulses a half as wide as clock pulses generated by a VCO5 in a synchronous state, and an MM14 triggered by an AND10 generates pulses a half as wide as the pulses of the MM2. An FF15 stores whether the output phase of the VCO5 leads that during complete synchronism, and an FF8 discriminates and stores whether the synchronous state is normal or not. The output of the MM2 is processed logically by an EXOR11, and ANDs 9, 10, and 12 according to states of the FFs 8 and 15 to control the VCO5 through a filter 4.

Title: Head speed control system
Inventor: ICHIKAWA TAKASHI
IPC: H02P29/00
Filed: 1986-05-07
Abstract: PURPOSE:To always move a head at correct speed, by measuring an error in a speed detector, etc., with a rotary disk shaped storage device itself, and correcting a targeted speed signal. CONSTITUTION:The interval of a pulse that is the output of a track cross detector 5 is time-counted by a timer means 12, and the speed of a head 3 is counted from the number of recording tracks crossed by the head 3, and a time required for that, while a targeted speed is kept at a regulated value level. And the targeted speed is corrected on the basis of a calculated result. Thus, since the rotary disk shaped storage device itself corrects the speed detection error of the head 3 in a field, an adjustment at a manufacturing time is made unnecessary, and also, change due to change in the lapse of time of a circuit element, or peripheral circumstance can be absorbed.
