Title: Masayuki Wada: Innovator in Programmable Controllers
Introduction
Masayuki Wada, an inventive mind based in Katsuta, Japan, holds five patents to his name. His work primarily focuses on programmable controllers, showcasing his expertise and dedication to technological advancements in this field.
Latest Patents
Among his latest innovations is a sophisticated programmable controller designed with safety features that detect overcurrents. This controller is equipped with an overcurrent detection portion, an overcurrent indication portion, and a transistor to interrupt load current when an overcurrent occurs. It contains an overcurrent detection resistor in the output transistor circuit, which allows for detection of voltage across the resistor. This voltage is then compared with a reference voltage in an overcurrent detection circuit to determine if an overcurrent is present. Once recognized, the system operates the overcurrent indication portion and regulates the base current to protect the output circuit. This innovative design ensures that when an overcurrent is detected, the output transistor is automatically switched off, alerting the user to the overcurrent state.
