摘要： In an automatic focus adjustment apparatus with a light-emitting device comprising a condenser lens and a light-emitting element which radiates light onto an object and adjusts the focal point according to a light reflected back from the object, undesired flare is eliminated by placing a diaphragm sufficiently close to the light-emitting element so that only the effective light from the element passes to the condenser lens by using a cap, an opaque paint or a spatial filter, and/or by applying a low reflectance paint to the inner wall of an outer casing of the light-emitting device.

摘要： A pulse signal amplitude storage-holding apparatus utilizes a plurality of series connected storage-holding circuits which store and hold the pulse magnitude of an electrical pulse signal whose amplitude is to be stored. At least one electrical pulse signal amplitude compensating circuit may be added to compensate for a storage error with respect to the pulse magnitude of the electrical pulse signal caused by the charge and discharged characteristics of each of the storage-holding circuits. In the alternative, at least one of the storage-holding circuits may be arranged so as to output an output signal accompanied by an overshoot of a fixed amount with respect to the input pulse signal, the overshoot thereby compensating for the abovenoted storage error.
