IPC: H02P29/00
Filed: 1994-09-29
Abstract: PURPOSE: To reduce the consumed current of a thread motor, by drive-controlling the thread motor through the output of a dead-zone circuit which generates the dead-zone output responding to its input, after the input level or a tracking error signal exceeds a level not smaller than the threshold level of the dead-zone circuit. CONSTITUTION: From a tracking error signal (TEO), its low-frequency component is extracted by a low-pass filter 1, and is amplified by a non-inverting amplifier 2. An amplified voltage VI is inputted to a dead-zone circuit 3, and an output voltage VO subjected to a precdetermined dead-zone characteristic is obtained. When a voltage VI-VD (VD is the forward voltage drop of a diode) exceeds an offset voltage VC, the output voltage of an operational amplifier 31 nearly becomes -B, and this negative voltage -B is fed to the base of a switching transistor (Tr) 32 via a resistor R5, and then, the transistor Tr 32 is turned off. At this time, the value of VI is so set as to be a value not smaller than the starting voltage of a thread motor 5.  As the output voltage VO of the circuit 3, the input voltage VI is fed to a motor driving circuit 4 via a resistor R1, and thereby, the thread motor 5 is started.

Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To surely feed a film frame and charge a shutter from force for transferring a photographic film provided with perforations arrayed alternately at two kinds of intervals. SOLUTION: A sprocket 29 is constituted of a wheel member 27 having a pair of teeth 27a and 27b engaged with a pair of perforations arranged side by side at a short interval and a rubber band 28 arranged exposedly on the circumference of the wheel member 27, in a state where a pair of the teeth 27a and 27b are exposed outside and the circumferential length of the sprocket 29 is made shorter than the one-frame feeding length of the film.

     CONSTITUTION: A perform of fiber reinforcement is formed by binding a fiber reinforcement, e.g. of Al 2 O 3  fibers together by the use of SiO 2 . After the above fibers are coated with a precursor for SrO, such as Sr(NO 3 ) 2 , Sr(CH 3 CO 2 ) 2 , and SrCO 3 , SrO is formed under heating to apply coating. Subsequently, a melt of Al-Si alloy, containing Sr by an amount necessary for modification, is allowed to penetrate into the resultant SrO-coated preform of fiber reinforcement under pressure. An alloy containing about 5-15wt.% Si is preferred as the above alloy, and proper content of Sr is about 0.05-0.4%. At the time of the above penetration, SrO is reduced by the molten alloy, and a monomolecular layer of Sr element at least is formed on the preform. Then, the resultant composite is cooled and solidified. By this method, the metal matrix composite, having fine crystals and excellent in physical properties, can be obtained.
