Title: Autofocus initial locking device in optical information reading device
Inventor: KUWABARA TOORU
IPC: G11B7/085
Filed: 1983-12-01
Abstract: PURPOSE:To attain automatic focus control having a servo loop locked without fail at descending even if the locking is failed when a focus lens is elevated by bringing the characteristic of a focus servo means into the control region. CONSTITUTION:A polarity switching circuit 13 switches the polarity of a focus error signal (d) of a differential amplifier 8 by detecting the leading of a level detecting output (f) so as to invert the input signal of a zero cross detecting circuit 12. A focus zero cross signal (e) of the circuit 12 goes to an H level in this case. A switch changeover signal (g) rises at the same time, a changeover switch circuit 11 impresses a signal proportional to a discharge voltage of a charge/discharge circuit 14 to an electromagnetic actuator 3 and the descending focus lens 5a is followed to the discharge characteristic. The descending lens 5a falls down slowly in following to the discharge characteristic in this case, and when the lens reaches the vicinity of the focal point, a level detector 9 rises and goes to an H level, the signal (e) descends and a signal (g) rises at the threshold value just before the signal (d) crosses over the GND level and the circuit 11 forms a switched servo loop.

Abstract: PROBLEM TO BE SOLVED: To construct a continuous wall in a short period by constructing a caisson with a wall at an erected state on the top of two caisson boxes at the central part separately laid out and a sinking this caisson. SOLUTION: A wall 3 is integrally constructed in an erected state on the top of cylinder-shaped caisson boxes 2 at the central part separately laid out along the extending direction of a reinforced concrete-made continuous wall to be constructed. The lower end of the wall 3 forms a cutting edge which is downward tapered. The caissons 1 thus formed as described above are set up in specified locations. When the ground is excavated in a work space, the wall 3 fits in the ground from the cutting edge 3a accompanied by the settlement of the ground. When the caisson boxes 2 sink up to a specified depth, a continuous wall is constructed with the wall 3 projecting in the ground. Since it is possible to omit excavation work between the caisson boxes 2, the amount of excavation is reduced, which makes it possible to cut down construction cost and shorten a construction period.

Abstract: PURPOSE:To reduce a synchronization time of a demodulator and to attain quick line connection control by releasing the holding state of a synchronization frequency of a carrier recovery circuit after a frequency synthesizer of other demodulator is set. CONSTITUTION:A common line signal control (CSC) circuit 4 designates a same reception channel to a demodulator 3 as that of a demodulator 2 when the demodulator 3 is not in operation. Thus, a frequency 302 and a carrier recovery device 303 are operated and synchronized with the reception channel of the demodulator 2. When the reception channel is designated to the demodulator 3 in this state, the circuit 4 turns off a hold switch 315 to allow a hold capacitor 316 to hold a just preceding VCO control voltage. Then the circuit 4 sets a parameter of a loop filter 307 and a band width of LPFs 310,311 in response to the modulation speed and the synthesizer 302 is synchronized. Thus, the synchronization establish time of the recovery device 303 is decreased and the line connection delay time is minimized.
