Abstract: PROBLEM TO BE SOLVED: To unnecessitate an additive device of a photosensor, etc., and to discriminate a disk diameter. SOLUTION: A agin capable of rotating a 12cm CD is set, and a servo is turned on (ST1 and ST2). The CD is steadily rotated at the same revolving speed irrespective of its disk diameter (ST3 and ST4).

Title: Automatic focusing method
Inventor: IMAKI KOJI
IPC: G02B7/28
Filed: 1989-10-30
Abstract: PURPOSE:To terminate automatic focusing in a short time by returning a lens by this side of a focal point, advancing a lens location one by one step each, calculating a focus evaluation for each step and moving the lens up to the focal position while the position of the lens is confirmed. CONSTITUTION:When a lens is restored to a focal position (a) (position at which maximum focus evaluation is obtained) after passing through the focal position (a), the lens is returned once onto this side (b) of the focal point. Every time the lens position is advanced by one step, the focus evaluation is calculated and the focal point is decided while the lens position is confirmed based on the focus evaluation. Even when the focus adjustment mechanism is unstable or the optical system has a steep change in a focus evaluation curve, the lens is quickly set to the accurate focal position (a) without trying the automatic focusing again.

IPC: G10K11/16
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To realize a silencing system requiring neither digital signal processing part nor duct. SOLUTION: When a fan 11 starts to operate, a fan noise having an extremely strong correlation with the frequency (characteristic frequency) corresponding to the rotating speed of the fan x the nubmer of blades 17, 17... is generated. A reference signal generating circuit 18 generates a reference signal. RS of the frequency corresponding to the value obtained by multiplying the rotating speed of the fan 11 by the number of the blades 17, 17.... A phase inverting circuit 19 inverses the phase of the inputted reference signal RS and outputs the resulting signal as a control sound signal SP. An amplifier 20 amplifies the control sound signal SP in a preliminarily regulated prescribed amplification degree, and outputs the resulting control sound signal.  A silencing speaker 12 emits a control sound of an opposite phase having the same amplitude as the fan noise on the basis of the amplified control sound signal SP.
