  • Publication number: 20230006628
    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.

  • Patent number: 10097929
    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.

  • Patent number: 8147565
    Abstract: An electrode plate precursor on which an active material layer is formed by applying an active material onto at least one surface of a current collector in a lengthy belt shape by means of a die comprising a paste storing part where a paste containing the active material is accumulated and a discharge flow path discharging the above paste from the paste storing part. A plan view configuration of the discharge flow path is adjusted by adjusting a plan view configuration of thin plate-like members that are arranged respectively on both end portions of the discharge flow path so that the active material layer formed in the process has a uniform thickness throughout the entire length in the width direction of the electrode plate precursor.

  • Publication number: 20100330267
    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.
