Abstract: In a multi-wavelength spectroscopic apparatus using diffraction gratings, a first diffraction grating is a diffraction grating with diffraction efficiencies of p-polarized light and s-polarized light being equal on a short wavelength side of an operating wavelength range, and a second diffraction grating is a diffraction grating with diffraction efficiencies of p-polarized light and s-polarized light being equal on a long wavelength side of an operating wavelength range. By performing dispersion with two such diffraction gratings, it is possible to enlarge the amount of angular dispersion, and to produce a spectroscopic apparatus, which cancels wavelength dependencies of the diffraction efficiencies and has a small wavelength dependency of the diffraction efficiency.

Abstract: 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.
