Title: Haruhiko Inoue: Innovator in Thin Film Technology and Sound Production
Introduction
Haruhiko Inoue is a notable inventor based in Nagoya, Japan. He has made significant contributions to the fields of thin film technology and sound production. With a total of 4 patents to his name, Inoue's work showcases his innovative spirit and technical expertise.
Latest Patents
One of Inoue's latest patents is a thin film resistor designed for strain gauges. This resistor is prepared through physical or chemical vapor deposition and contains 60 to 98 atomic % of chromium, 2 to 30 atomic % of oxygen, and 0 to 10 atomic % of a metal or semiconductor. The constituents are uniformly distributed, and the film thickness ranges from 0.01 to 10 micrometers. The metal used can include aluminum, titanium, tantalum, zirconium, and indium, while the semiconductor may consist of silicon, germanium, or boron. This thin film resistor exhibits excellent resistance-strain characteristics, resistance-temperature characteristics, high sensitivity, and mechanical strength.
Another significant patent involves a warning chord sound producing apparatus that includes an integrated circuit. This device features a 1-bit microcomputer driven by a clock signal, which has first and second output ports. The signals from these ports control first and second transistors, whose output signals are supplied to step-up transformers. These transformers drive sounding devices made of piezoelectric elements to produce a chord sound. The microcomputer's memory stores a program that outputs first and second square-wave pulse-train signals, each with a different basic frequency.
