Title: Tetsu Odohira: Innovator in Semiconductor Technology
Introduction
Tetsu Odohira is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to pressure measurement devices. His work has implications for various applications in electronics and measurement systems.
Latest Patents
One of his latest patents is the **Semiconductor Pressure Converter**. This device applies a drive voltage to a power supply end of a shearing type gauge formed at the strain generating part of a semiconductor diaphragm. The output voltage is amplified with an amplifier, and the zero point is adjusted by applying a bias voltage related to the drive voltage. The span is adjusted without interference to the zero point by changing the feedback voltage of the amplifier. This invention achieves linear compensation, temperature zero point compensation, and temperature span compensation without mutual interference.
Another significant patent is the **Capacitive Type Converter Device**. This device is used for measuring pressure and comprises first and second rectifying circuits, each including an operational amplifier. The non-inverting input terminal is connected to a reference point, where a variable condenser is connected. The variable condenser's capacitance varies in response to the force being measured, such as pressure. The device also includes an oscillator controlled by a control means, which responds to the output of the rectifying circuits. This invention eliminates adverse influences of stray capacitances, non-linearity, offset signals, and parallel capacitances.
