    摘要: The output from a digital signal amplitude regenerator circuit in which the amplitude of a transmitted burst data signal is amplified, and an initial potential generator circuit, are connected to a switch. While there are no burst data, the initial potential generator circuit provides a circuit for compensating for degradation in pulse width comprising a low-pass filter, a pulse width compensation threshold generator circuit, and a limiting amplifier, with an initial potential needed to set a threshold. When a carrier detection signal generator circuit detects the arrival of a burst data signal, a carrier detection signal is outputted, and the switch is switched over from the initial potential to the burst data signal. Thus, the circuit for compensating for the degradation in pulse width located at a later stage can detect a threshold from an optimal initial potential, and thereby the degradation in pulse width can be optimally compensated.

    摘要: A battery protection circuit protects a rechargeable battery from overdischarge, by turning off a transistor inserted in series in a current path between a negative electrode of the battery and a negative terminal coupled to ground of a load or a charger. A detection circuit detects a power source voltage between power source and ground terminals, and a control circuit pulls down a monitor terminal potential to a ground terminal potential by turning off the transistor and stopping battery discharge when the power source voltage lower than an overdischarge detection voltage is detected. The control circuit cancels pull-down of the monitor terminal potential to the ground terminal potential when the power source voltage higher than an overdischarge reset voltage is not detected until a predetermined time elapses in a state in which the battery discharge is stopped and the monitor terminal potential is pulled down to the ground terminal potential.

    摘要: A wavelength selective switch for suppressing degradation of pass band characteristics when the temperature rises. The wavelength selective switch includes a spectroscopic element for separating input light and providing angular dispersion depending on wavelengths, a collective lens for gathering light output from the spectroscopic element, and a movable reflection block which includes a plurality of mirrors arranged in the direction of angular dispersion made by the spectroscopic element, changes the angles of the mirrors in a direction differing from the direction of angular dispersion, and reflects the light coming from the collective lens. The collective lens is fixed at one end with respect to the direction of angular dispersion, expands with heat in a direction in which it is not fixed when the temperature rises, and outputs the light in a direction opposite to the direction in which the angle of light output from the spectroscopic element changes.
