Title: The Innovations of Hichiro Ohtani: A Pioneer in Thermal Flow Sensing
Introduction: Hichiro Ohtani, an accomplished inventor based in Himeji, Japan, has made significant contributions to the field of thermal flow sensing. With a remarkable portfolio of seven patents, Ohtani's work has paved the way for advancements in the measurement and control of fluid flow in various applications.
Latest Patents: Among Ohtani's latest innovations are two notable patents. The first patent details a sophisticated thermal flow sensor designed such that the longitudinal axis of the thermal resistance element is angled between 10° to 80° in relation to the wires of a rectification net. This unique configuration ensures that the surface of the thermal resistance element remains consistent, minimizing discrepancies when the attachment positions of the various components change. This innovative design significantly reduces uneven characteristics even when the thermal resistance element is positioned close to the rectification net.
The second patent introduces a heat-sensitive flow sensor that employs a bridge circuit formed by a heat-sensitive resistor on a substrate within a fluid passage. This system includes multiple resistors and a control circuit that maintains thermal balance within the bridge circuit, allowing for reliable detection of flow rates. The design further enhances functionality by embedding current supply leads and the substrate's base portion within a heat-insulating support member, with lead terminals of the heat-sensitive resistor also buried for added efficiency.
