Title: The Innovative Contributions of Masao Shigyo
Introduction
Masao Shigyo is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of pressure measurement technology, holding a total of 14 patents. His work focuses on developing advanced methods and materials for accurately measuring pressure in various applications.
Latest Patents
One of Shigyo's latest patents is a pressure measuring film designed for measuring pressure in small contact areas. This innovative film utilizes a toner layer of a specific thickness held between an adhesive layer on a first support and an inactive adhesive layer on a second support. Before applying the pressure to be measured, the inactive adhesive layer is activated to become adhesive. Once the pressure is applied, the first support is removed, and the pressure is determined based on the amount of toner that adheres to the second support. This method allows for the measurement of extremely low pressures applied to very small contact areas, while remaining unaffected by varying conditions such as temperature and humidity. Additionally, the inactive adhesive layer can be made from a thermoplastic resin adhesive that activates through heating.
Another notable patent involves a method for measuring pressures that exceed the measurable range of the pressure measuring film. This method employs a pressure measuring film that develops color in proportion to the applied pressure. An elastic sheet is placed between the pressing surfaces and the pressure measuring film to reduce the pressure transmitted to the film. The pressure distribution is then analyzed from the colored image on the film to determine the actual maximum pressure applied between the surfaces. This technique enables the measurement of large pressures that fall within or exceed the film's measurable range.
