Abstract: PROBLEM TO BE SOLVED: To easily adjust the position in an asynchronous direction of the lens of an optical system by providing a driving source for moving a lens, which is installed in either a 1st or a 2nd fixed base. SOLUTION: A rail end in a direction where the lens is moved when an original image is reduced is fixed on the plate-like fixed base (fixed plate) 372 through a machine screw. A pulley gear 374 for a belt is rotatably fixed on the plate 372. Meanwhile, the rail end in a direction where the lens is moved when the original image is enlarged is fit and supported on the plate-like fixed base (fixed plate) 376. A stepping motor 356 for moving a lens is fixed near a rail supporting part or the rail end through a motor mount plate on the plate 376. Therefore, the plates 372 and 376 are respectively independently moved in the asynchronous direction of the lens.

Filed: 1990-03-08
Abstract: PURPOSE:To save a stuff memory capacity by using the phase difference information of a write and readout address counter and an input/output frame counter to recognize the time of write side phase jump. CONSTITUTION:An input frame counter FC1 and an output FC2 represent the phase information of an input frame and an output frame and a phase comparator 3 outputs the phase difference (x) of them.

Title: Sound receiving device for suppressing noises
Inventor: OOGA TOSHIROU
IPC: H04R3/00
Filed: 1984-03-27
Abstract: PURPOSE:To enable hearing of sounds which are masked by noises and hard to be heard and to reduce an unpleasant feeling in terms of acoustic sense by adding a signal transmitted through a switch to the signal whose maximum frequency band is delayed so as to output the added signal. CONSTITUTION:A switch 19 is switched to the side of a delay circuit 17 in the normal condition, while a voltage of an output signal eo is turned into a waveform obtained by delaying a voltage of an input signal ei by means of delay circuits 14 and 17. Noises have mainly low frequency components, and a long hours average spectrum is dominated by low band components. As a result, a discrimination circuit 22 will not operate, and the switch 19 is almost switched to the side of the circuit 17. However, a sound has more peak components compared with noises. Accordingly, when the sound is made incident on, a level of a high band signal en exceeds a threshold at a part 24, where the circuit 22 operates, and the switch 19 inverts. Consequently a low band level of the output voltage eo is reduced from an output eld to an output eld' of an arithmetic circuit 18 at the part 24.
