Title: Servo circuit for disk device
Inventor: SHINOHARA TORU
IPC: H02P25/034
Filed: 1989-01-31
Abstract: PURPOSE:To contrive the high speed of seek access with a small difference quantity by forcibly adding a prescribed value for acceleration to the difference signal of a servo loop in accelerating stage at the time of a seek start. CONSTITUTION:An accelerating means 14, which forcibly adds a prescribed value Ecc for acceleration to a difference signal DELTAE in the accelerating stage at the time of starting a speed control, is provided in a servo loop. The accelerating means 14 is provided with a switching means 18, which selectively supplies the prescribed value Ecc for acceleration to an adding point 16 where the difference signal DELTAE of the servo loop is inputted, it turns on the switching means 18 at the time of the seek start, and turns off the switching means 18 at the time of detecting acceleration completion. Consequently the prescribed value Ecc for acceleration is forcibly added to the servo loop regardless of the difference DELTAE between a target speed E1 and a practical speed E2. Thus even when the difference quantity is small, the accelerating current excellently rises, and the high-speed access is attained.

IPC: H03F3/45
Filed: 1985-02-06
Abstract: PURPOSE:To prevent latchup without decreasing the dynamic range of the titled circuit by providing a comparator detecting the abnormity of a DC level of an output so as to turn off an active load of an output circuit. CONSTITUTION:The output of an emitter follower transistor (TR)Q7 leading an output of the 2nd differential amplifier 2 and feeding it back to the 1st differential amplifier 1 is converted into a DC output by a diode D2 and compared with a reference level Vr by a comparator 3. When the potential of the TRQ7 gets abnormally high, a TRQ9 of the comparator 3 is turned on and a TRQ10 is turned off and then a TRQ11 is turned off. As a result, a TRQ8 being an active load of the 2nd differential amplifier 2 of current mirror constitution with the TRQ11 is turned off, the base voltage of the TRQ7 is decreased and the TRQ9 of the comparator 3 is turned on and the TRQ10 is turned on so as to activate the TRQ8 being the active load normally.

Filed: 1991-01-21
Abstract: PURPOSE:To obtain a plastic molded part having high dimensional accuracy by a method wherein the wall thickness of the region corresponding to the gate part formed in the plastic molded part is made larger than that of the remaining region. CONSTITUTION:The plastic gear concerned as a plastic molded part consists Of teeth 1, a rim 2, a recessed disc part 3 and a hub 4 and integrally formed by injection-molding engineering plastic material. On the disc part 3, a plurality of pin gate marks 5 due to injection molding are present. In this case, the disc part 3 is formed by continuously and circumferentially changing its wall thickness. Concretely, the wall thickness T1 of the disc part 3 in the region corresponding to the pin gate mark 5 is the maximum thickness, while the wall thickness T2 of the disc part 3 between the pin gate marks 5 is the minimum thickness. Thus, the amount of shrinkage in the region having the wall thickness T1 becomes larger, resulting in allowing to mold the external form dimensions, pitches and the like of the plastic molded part with high accuracy.

Title: Synchronization protecting device
Inventor: YOSHIKAWA YOSHINOBU
IPC: H04L7/08
Filed: 1985-02-06
Abstract: PURPOSE:To recover the synchronization in a comparatively short period even in case a synchronizing signal has the start-stop shifting, by resetting a synchronization period while the synchronizing signal is stable at the outside of a window. CONSTITUTION:When data are sent to a synchronization detector 1, the synchronizing signal is sent out. This synchronizing signal usually resets a free-running counter 3 and a front side protecting counter 4. A window generator 2 estimates the position of the next synchronizing signal and sends the window output to the counter 3. A synchronization counter detector 5 monitors the position of the synchronizing signal and then decides that the positions of the past signals i+2, i+3 and i+4 are cynchronous with the position of the signal i+5 at a time point the signal i+5 is supplied and that a signal trains is stable at the outside of the window in case the signal i+2 has the start-stop shifting. Then the detector 5 delivers a hunting signal. With this hunting signal, a synchronizing period is reset at a time point the signal i+7 is supplied. The synchronization period is cut down to five frames in an asynchronization period.
