Abstract: PURPOSE:To reduce an increase in insertion loss originating from an increase in fiber gap and to obtain a stable optical switch by forming the mutually opposite end surfaces of a movable fiber and fixed fibers into convex surface shape. CONSTITUTION:The mutually opposite end surfaces 20, 21 and 22 of the movable fiber 2 and fixed fibers 4A and 4B are formed into convex surface shape, a housing 11 is covered with a cover 23, and a groove 24 for setting the fiber gap is formed on one side of the housing 11 where a fiber insertion hole 12 is formed. A polishing method or heat fusing method is employed to form the end surfaces 20, 21 and 22 into the convex surface shape. Thus, the mutually opposite end surfaces 20-22 of the movable fiber 2 and fixed fibers 4A and 4B are machined into the convex surface shape, so as optical coupling system which is similar to a collimated beam system is formed between both fibers 2, 4A and 4B, the tendency of the loss increase resulting from the increase in the fiber gap is reduced, and the stable optical switch is obtained.

Title: Level shift circuit
Inventor: HANABUSA HIRONORI
IPC: H03F3/34
Filed: 1988-06-20
Abstract: PURPOSE:To prevent variance caused among elements by providing a current conversion means, a current subtraction circuit and a voltage conversion means and actuating the input voltage signal so that the DC voltage level is shifted to the prescribed voltage which serves as the reference of the voltage conversion means. CONSTITUTION:It is supposed that the gate width and the gate length are equal to each other among transistors MB and M1-M12. When the signals inputted to a negative input terminal MIN and a positive input terminal PIN are set at zero, the current IB/2 (IB: drain current of bias current) flows to the M1-M4 of a first amplifying part 2. Thus the drain potential of the M4 is equal to the potentials of the gate and the drain of the M3. As a result, the current IB/2 also flows to the M6 and M11 and the drain current of the M7 is equal to IB/2. Then the current IB/2 also flows to the M12 and the drain current of the M11 is equal to that of the M12. Thus the drain current flowing to each transistor is stabilized against the variance of elements.

IPC: C23C2/00
Filed: 1989-06-14
Abstract: PURPOSE:To suppress the rising of the bottom dross accumulated in the bottom of a plating cell and to obtain a steel sheet having excellent plating appearance and corrosion resistance by disposing a shielding plate for suppressing the flow of a plating bath from below a sink roll between the sink roll in the cell and the cell bottom. CONSTITUTION:A strip 14 entering the above-mentioned plating cell is wound around the sink roll 16 and is pulled again upward. The shielding plate 30 is provided below the roll 16 between the cell bottom and the roll. The accompanying flow arising from the traveling of the strip 14 is shielded by the shielding plate 30, by which the influence of the above-mentioned flow is drastically lessened. Since the influence on the bottom dross accumulated in the lower part is thereby averted, the soaring up of the bottom dross is drastically decreased and the generation of the dross defects on the strip 14 is considerably suppressed. N2 is blown simultaneously with the addition of Al to the bath to float the bottom dross and to discharge the same from the bath at the time of standing by. The plates shown in Figs, (a) to D) are used as the shielding plate 30.
