摘要： In an equalizing amplifier that equalizes an electric signal obtained from a light signal received via an optical transmission path, an AGC circuit generates first and second signals from the electric signal by referring to a threshold voltage. The first and second signals are complementary signals. An offset compensation circuit generates a first difference signal based on a difference between the first and second signals, compares the first difference signal with a first reference signal, and outputs, as the threshold voltage, a resultant error signal to the AGC circuit. The threshold voltage is varied so that it is located in the center of an amplitude of the electric signal whereby an offset of the AGC circuit can be compensated for.

摘要： A reactor is disclosed. The reactor is comprised of a housing, a solenoid coil, a center columnar member, and a core. The center columnar member provides first surfaces contacting with sandwich portions of the housing, and the core is comprised of resin including magnetic powder. The coil and the center columnar member are fixed in the core. A surface roughness (Rz2) of a second surface which contacts to the core is larger than a surface roughness (Rz1) of the first surfaces. The center columnar member further provides a basis surface of which roughness (Rz3) is smaller than the Rz2 and larger than the Rz1.

摘要： A second member is superposed on a first member. A first recognition mark is described on the surface of the first member. A second recognition mark is described on the surface of the second members. The first recognition mark is fragmented along the edge of the second member when the second member is superposed on the first member. The second recognition mark ends at the edge of the second member. The second recognition mark cooperates with the first recognition mark for establishment of a predetermined geometric pattern. The relative positions of the first and second recognition marks can be adjusted based on an irregular or unshaped geometric pattern. The second member can thus reliably be superposed on the surface of the first member at the correct position.
