IPC: G02B7/02
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To confirm a photographing distance to a subject without increasing production cost by providing a manual focusing operation ring with a different shape part whose shape is different from other surface and expressing the photographing distance to the subject according to the position in the rotating direction of the different shape part. SOLUTION: By rotating the MF operation ring 7 around an optical axis, the rotational motion is converted into straight advance motion in an optical axis direction in a male helicoid and a female helicoid, so that the ring 7 is moved back and forth in the optical axis direction so as to perform focusing. Since the ring 7 is provided with grooves 7d, 7e and 7f having the shape which can be discriminated from other parts at positions corresponding to the specified photographing distance on the outer peripheral surface of the ring 7, the distance at that time is confirmed by observing the positional relation among an attaching/detaching index 2e, a zooming index 2f and the grooves 7d, 7e and 7f. Thus, the space for the ring 7 is effectively utilized and the compact and inexpensive lens barrel is obtained.

Title: Time division multiplex transmission system
Inventor: OGURA YOICHI
IPC: H04J3/00
Filed: 1990-04-03
Abstract: PURPOSE:To minimize the change in the system by using a prescribed high-order bit not contributing to signal coding, applying time division to a data signal other than a composite video signal and sending the signal. CONSTITUTION:Since various signals sent for horizontal and vertical blanking periods in a composite video signal reach a prescribed level depending on the kind of signal, several bits from the MSB are not used for coding for the horizontal and vertical blanking periods when the composite video signal is subject to linear coding by the PCM code or the like. Then bits not in use are utilized to use the data such as voice signal for the transmission. That is, the data signal such as the voice signal is multiplexed digitally to a part without information substantially in the digital composite video signal to be coded. Thus, no processing is applied to the original video signal data and the revision in the system is minimized.

IPC: G05F1/56
Filed: 1978-07-25
Abstract: PURPOSE: To obtain a power circuit which allows a positive or negative output voltage to fall or annihilate following up a decrease or even annihilation in the other voltage, by using a field effect transistor or an element with the identical function or the both combined.  
     CONSTITUTION: When diodes X1, X2, and X3 and resistances R12 and R13 are added to amplifier circuit IC1 and IC2, normal control allows X1 and X3 to be ON and X2 to be OFF, so that Zener diode ZD1 will stabilize a negative voltage while equalizing a positive voltage to the negative voltage. The positive voltage falls or  annihilates following up a decrease or annihilation in the negative voltage. However, once the positive voltage falls or annihilates, the negative voltages voltages  falls or annihilates following up the positive voltage through the switching of diodes. Further, the positive voltage may be stabilized at the time of normal operation so as to allow the negative voltage to follow up.
