    摘要： A light receiving amplifying device includes a light receiving device for outputting a light signal current which varies with a quantity of received light, a load resistor connected with the light receiving device in series, for generating a detected voltage which varies with the light signal current, and a low frequency current bypass circuit for preventing the detected voltage from being saturated when the detected voltage has a frequency in a low frequency band. The low frequency current bypass circuit is connected with the load resistor in parallel and has an input impedance varying with a frequency of the detected voltage. The device further includes a transimpedance amplifying circuit (inverting amplifying circuit) for transforming an impedance of the detected voltage, and a capacitor for coupling the low frequency current bypass circuit and the transimpedance amplifying circuit (inverting amplifying circuit). This makes it possible, with a relatively simple circuit and arrangement in an infrared communication receiver, to lower noises of the light receiving amplifying device while maintaining an operational range with respect to a DC photoelectric current.

    摘要： Provided is a liquid discharging apparatus including a container containing a liquid composition containing water, an organic solvent, and a polyurethane resin, and a discharging head. The discharging head includes: an individual liquid chamber including a circulation flow path through which the liquid composition circulates; and a nozzle communicating with the individual liquid chamber and through which a liquid droplet of the liquid composition is discharged. The solid content of the polyurethane resin in the liquid composition is 7.0% by mass or greater but 20.0% by mass or less.
