摘要： A wave-shaping circuit for receiving an electrical signal from a photosensitive device, for example, and delivering a rectangular output does not use an expensive DC amplifier but comprises a comparator, a pair of diodes connected between first and second input terminals of the comparator in an antiparallel relation, and a capacitor placed between the first input terminal of the comparator and the signal input terminal of the circuit for filtering out DC component. A combination of a zener diode and a capacitor is connected to the second terminal of the comparator to establish a threshold level, with which the signal level applied to the first input terminal of the comparator is compared.

摘要： Current mirror circuits that are parts of a first circuit and a second circuit, respectively, allow the same constant current to flow through the input side and the output side. Therefore, the base-emitter voltages of transistors Tr1 and Tr4, which tend to vary due to a temperature variation, can be set identical and hence can cancel out each other sufficiently. The same is true of the base-emitter voltages of transistors Tr5 and Tr8. Therefore, an input signal can be converted by a function having reference voltages as change points without being affected by temperature. Desired function circuits can be obtained by combining first circuits and second circuits in various manners.

摘要： An optical branching device includes a main waveguide and a branching waveguide. A portion of the main waveguide is bent and the branching waveguide is placed close to the bent part of the main waveguide. The branching waveguide has a taper structure such that a width of the branching waveguide is gradually decreased in a propagation direction of light. A central axis of the branching waveguide is tilted from a line extended from a straight part of the main waveguide toward the direction X, or the bending direction of the main waveguide. An input end of the branching waveguide has a normal vector tilted from the central axis of the branching waveguide toward the direction Y, an opposite direction of the bending direction of the main waveguide. With above-mentioned structures, light radiated from the bent part of the main waveguide can be launched into the input end of the branching waveguide and transmitted through the branching waveguide efficiently.
