Title: Masazumi Shiochi: Innovator in Circuit Design
Introduction
Masazumi Shiochi is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of circuit design, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
One of his latest patents is the "Wiring Open Detection Circuit." This invention includes a signal processing circuit, a terminal, a diode, and an open decision circuit. The signal processing circuit is connected to one end of a first wiring and outputs a signal processed signal to the first wiring. The terminal is connected to the other end of the first wiring. The diode has one end connected to the terminal. The open decision circuit applies a first voltage to the other end of the diode and detects changes in the current flowing in the first wiring to decide whether or not the first wiring is open.
Another significant patent is the "Insulated-Gate Semicustom Integrated Circuit." This invention incorporates pull-up and pull-down MOS transistors designed to manage the potential of a signal line connecting a protection circuit with an internal circuit. The MOS transistors have their drains connected together to the signal line and their sources connected to a pull-up or pull-down power supply node as required. This design enhances the electrostatic breakdown strength of the internal circuit without increasing the occupied area of the protection circuit in the integrated circuit.
