Abstract: PROBLEM TO BE SOLVED: To provide a build-up multilayered wiring circuit board which does not cause further electric problems, such as a signal delay and reflected noise, even if a two-layer conductor interconnecting layer having a superior adhesion and conduction with an insulating layer is formed. SOLUTION: On an insulating layer 2 formed on a metallic board 1, an adhesive conductor layer 3, and a conductive conductor layer 4 are formed. After that, a metal conductor pattern layer 6 is formed by electrolytically plating with a resist pattern 5 as a mask, then the resist pattern 5 is removed, the adhesive conductor layer 3 the conductive conductor layer 4 are etched with a metal conductor pattern layer 6 as a mask to form a three-slayer conductor interconnecting layer 7 constituted of the metal conductor pattern 6, a conductive conductor pattern layer 4a, and an adhesive conductor pattern layer 3a. In order to connect these conductor interconnecting layers electrically, a via hole 9 made of a conductive conductor is formed at the center of a land for connection of the conductor interconnecting layer 7.

Abstract: PURPOSE:To miniaturize a low-pass filter without response delay by shifting timing of switching of switching elements, sampling an output detection signal and converting timing of sampling into a digital signal. CONSTITUTION:A delay circuit 13 is started from a rising point of time of an output signal (c) of a sawtooth wave generator 15 and a pulse is generated after the set time td. This pulse is supplied to an A/D converter circuit 11 as a sampling pulse. The A/D converter circuit 11 samples and takes in the signal via the low-pass filter 10 of the output If of an output current detector 9 for every sampling pulse and converts it into the digital signal (d) and supplies it to a comparator 14. The comparator 14 compares the output I of a reference signal generation circuit 13 with the output (d) of the A/D converter circuit 11 and outputs an error signal  I which is compared with the output (c) of the generator 15 and a signal (s) to continue the switching elements 3a and 3b is outputted only for a period of I>(c). By this method, mixing of noise can be prevented.

IPC: G02B7/04
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To reduce backlash or a time lag and to manually drive or motor- drive an optical means without necessitating special switching operation by specifying the relation of each torque in a motive power transmitting mechanism which drives the optical means or transmits rotational motive power. SOLUTION: Respective elements are set to satisfy TL<TF<TM when it is assumed that the torque required to drive a manual ring 11 to a moving lens group 3 by a magnetic force coupling means is TL, the limit torque which can be transmitted by the magnetic force coupling means is TF, and the limit torque which can be maintained by a driving system with respect to the driving force from an output side is TM. In the case of manual driving, the ring 11 is turned to restrict the driving force transmitted to the driving means 6 and 7 by slip torque between a thin plate and a spacer. Even when force is exerted from the outside in the midst of motor-driving 12, the magnetic force coupling means does not transmit load torque exceeding specified load torque, so that unnatural force is not exerted on a mechanism system.  Thus, the lens group 3 is driven in a state where the mechanism is simplified without necessitating the mechanism for switching the driving from motor to mannula and vice versa.
