Title: Lens barrel
Inventor: FUJIWARA YUTAKA
IPC: H04N5/232
Filed: 1991-08-07
Abstract: PURPOSE:To automatically set proper exposure by providing plural filters having the various kinds of transmittance in the lens barrel and selectively putting-in/out the filter onto an optical axis so as to obtain the proper quantity of light. CONSTITUTION:Plural filters 9a-9d are arranged with equal spaces with an axis 15 as a center on a ring-shaped turret 10. A control circuit 28 on the side of a main body 20 of a camera judges whether the exposure is proper or not corresponding to the quantity of light condensed through a lens barrel 19 to a CCD 21. When the exposure is not proper, a control signal is transmitted to a control circuit 14a in the lens barrel 19. The control circuit 14a transmits a driving signal to a motor 12 and simultaneously places the filter having the proper transmittance on the optical axis based on the detecting signals of patterns 16a-16d.

Abstract: PURPOSE:To stop smoothly a tape by calculating an optimum brake torque value during running of the tape and putting the counter electromotive force brake on a motor at a power break time on the basis of the optimum brake torque value calculated just before the power break. CONSTITUTION:A constant current circuit 3 is constituted with a transistor TR Q1, a winding current detecting resistance R1, an amplifier 7, etc. A voltage corresponding to the winding current detected by the resistance R1 is fed back to the amplifier 7. A control voltage EC of a servo circuit is applied to this amplifier 7 from a terminal 8. When a switch 1 is closed by the power break, the voltage of a capacitor C1 is applied to the base of a TR Q2. The emitter of this TR Q2 is connected to the resistance R1, and consequently, a voltage corresponding to the voltage between both ends of a T and the resistance R1 appears as an optimum torque value in the collector of the TR Q2. A TR Q3 is controlled by this voltage, and a current IM of the TR Q1 is controlled by the current flowing to the TR Q3. As the result, the T is controlled in accordance with the current IM, and the counter electromotive force brake is put on practically, and a motor 2 is stopped.

Title: Method and device for laser welding
Inventor: SAKURAI SHIGEYUKI
IPC: B23K26/21
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To realize a laser welding device which can carry out a secure crater treatment in a short distance and surely reduce thermal influence and thermal distortion at a portion where a welding area is narrow and at a corner part of an acute angle. SOLUTION: A laser 6 oscillated from a YAG laser oscillator 2 is incident on a parabolic mirror 9 via a mirror 8, reflected downward by 90 deg., and condensed to a work 13. A laser 5 oscillated from a CO2 gas laser oscillator 1 is bent at 90 deg. by a mirror 7, introduced on the same shaft as an optical axis of the YAG laser 6 by the mirror 8 installed on the optical axis of the YAG laser 6 and condensed to the work 13 by the parabolic mirror 9. Since penetration depth by the mixed laser of the CO2 gas laser 5 and the YAG laser 6 is not rapidly reduced, a key hole is not rapidly vanished. Therefore, generation of craters accompanied with a rapid power reduction caused in a case of welding by only the CO2 gas laser 5 can be prevented.  Additionally, compared with the case where only the CO2 gas laser 5 is used, a terminating treatment without generating the craters can be carried out in a short time and short distance.
