Title: Kunihiro Miyata: Innovator in Power Amplifier Technology
Introduction
Kunihiro Miyata is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of power amplifier technology, holding a total of 3 patents. His innovative work focuses on enhancing the safety and efficiency of power transistors and amplifiers.
Latest Patents
Miyata's latest patents include a protection circuit for a power amplifier and a protective apparatus for power transistors. The protection circuit for a power amplifier features a direct current voltages detecting circuit that monitors the output voltage of the amplifier. When a direct current voltage is detected, a direct current signal is produced. This signal activates a cutoff circuit that places the output stage of the amplifier in a cutoff state. Additionally, a failure determining circuit responds to the direct current signal to produce an abnormality signal. In response to this signal, a power supply cutoff circuit operates to disconnect the power supply of the amplifier.
The protective apparatus for power transistors is designed to detect abnormal temperatures in power transistors. It cuts the load to the transistor to prevent potential breakdowns. This apparatus includes detecting means that monitor the junction temperature of the transistor in real-time based on its base-emitter voltage. If the junction temperature exceeds safe limits, a protective circuit generates an output signal, and a muting circuit applies muting to the input signal or current flow through the transistor.
