Latest Patents

One of Ishii's latest patents is an audio signal output device designed to prevent optical signals from being output when a plug is not connected to an S/PDIF output terminal. This innovative device ensures that when a plug is disconnected, a fitting metal part does not contact a detection pin, resulting in a connection detection signal of 12V. Consequently, both a PNP transistor and an n-channel MOS transistor remain OFF, preventing the supply of a 5V power supply voltage to a drive IC, thus avoiding the output of optical signals. Another notable patent is for a portable information terminal device that features multiple casings providing both front and rear surfaces. These casings are designed to house speakers in a way that prevents resonance caused by vibrations, while also maintaining a compact size and lightweight design.
