Abstract: The present disclosure provides an audio circuit capable of inhibiting a current when mute is deactivated. An output terminal of a class D amplifier circuit is connected to an electroacoustic conversion element through a low-pass filter. An output node of a bridge circuit is connected to the output terminal. An integrator integrates and outputs, in a non-mute period in which a mute control signal is negated, a difference between an input signal and a feedback signal corresponding to an output signal generated at the output terminal, and outputs a predetermined bias voltage in a mute period in which the mute control signal is asserted. A PWM comparator compares the output of the integrator with a periodic voltage. A driver switches, in the non-mute period, the bridge circuit according to an output of the PWM comparator, and fixes an output of the bridge circuit in the mute period.

Abstract: A lever member of a lever assisted insertion device engages with a front frame of a shelf before a fully inserted position of a substrate unit to form a leverage fulcrum on the front frame. A force that an operator applies to the lever member is transmitted to the substrate unit via a point of application with respect to the fulcrum, thereby inserting the substrate unit up to the fully inserted position. A buffering device abuts against the front frame of the shelf within a depth range of a front panel of the substrate unit before an operation start position at which the lever member engages with the front frame of the shelf, to absorb impact of the substrate unit at the time of insertion.

Abstract: It is intended to easily separate saponins from isoflavones extracted from starting soybeans thereby giving highly pure saponins at a high yield on an industrial scale. Saponins can be highly efficiently separated from isoflavones by performing multistage extraction under mild conditions such that malonyl isoflavone glycoside, from among isoflavones contained in the starting soybeans, is not converted into isoflavone glycoside, acetyl isoflavone glycoside or isoflavone aglycon. Thus, highly pure saponins can be obtained at a high yield on an industrial scale.
