Abstract: A fuel cell system includes a microprocessor configured to perform, during an external power supply in which power is supplied to an external load, controlling a power generation of a fuel cell so as to generate a power at a predetermined power generation efficiency and supplying a surplus power not consumed out of the generated power of the fuel cell to a battery to charge the battery. The controlling includes, during the external power supply, stopping the power generation of the fuel cell when a charge rate of the battery becomes a first predetermined value or larger, controlling an output of the battery so that the power of the battery is supplied to the external load, and resuming the power generation of the fuel cell when the charge rate becomes a second predetermined value smaller than the first predetermined value or lower.

Abstract: Equipment that can comfortably hear mixed large sound and small sound at the same time by earphones and headphones is achieved. Level of rise and fall of an input signal waveform is logarithmically compressed and output to limit wave height, and an output signal is taken out from a wave-height-limited signal by eliminating or attenuating harmonic distortion. A limiter 6 limits an amplitude of an input sound signal. The integrator 7 is connected to the output-side of the limiter 6 and logarithmically compresses rise or fall of an output signal waveform from the limiter 6.

The speaker device includes a first speaker unit having a first diaphragm connected to a voice coil bobbin, and a second speaker unit having a second diaphragm provided inside the voice coil bobbin.

Abstract: When, in conventional sound systems, signals of sounds collected by a microphone are amplified and the amplified signals are applied to an ear by an earphone and a headphone, too loud sounds and environmental noises are unpleasant, and the intelligibility of words are poor. Hence, such problems are to be addressed. In addition, downsizing and performance improvement for sound apparatuses are to be accomplished. A signal having undergone an amplitude limitation with reference to an output potential of a high cut filter 17 which is an output by a low cut filter 12 in a high frequency band and inverted by an inverter 14 is added with, by an adder 15, an output signal from the high cut filter 17, and an addition signal is output.

Abstract: A production method of the present invention includes steps of: (a) obtaining a first electrode plate precursor 1 by applying an electrode active material onto at least one of surfaces of a long strip-shaped current collector so as to form an active material layer, (b) rolling an electrode plate precursor so that the active material layer has a predetermined thickness, and (c) obtaining plural strips of electrode plates by cutting the rolled electrode plate precursor to a desired width. In the step (a), non-application portions onto which an active material is not applied are formed on both edges of the electrode plate precursor in the width direction. The step (d) of removing the non-application portions is carried out simultaneously with the step (c). Accordingly, it is possible to improve production efficiency and reduce material losses by decreasing quality defects that occur in the step of rolling the electrode plate precursor.
