Title: Innovations of Hiroyuki Horiguchi
Introduction
Hiroyuki Horiguchi is a prominent inventor based in Yokohama, Japan. He holds a total of 16 patents, showcasing his significant contributions to the field of flow measurement technology. His innovative designs have advanced the accuracy and efficiency of flow meters, making them essential tools in various industries.
Latest Patents
One of Horiguchi's latest patents is a thermally-sensitive type flow meter that measures flow rates with high accuracy by eliminating noise generated in a source voltage. This flow meter includes a sensor chip with a substrate carrying sensing elements. It features first and second resistors on bridges formed over a depression on the substrate, with the first bridge positioned upstream and the second downstream. These resistors generate heat from the same voltage source, while temperature measuring resistors monitor their temperatures. A temperature control unit ensures that the temperatures of the resistors remain constant, allowing for precise flow rate determination based on voltage differences.
Another notable invention is a heater-heat sensor type thermal flow sensor. This device includes a substrate installed in a fluid path, with a channel formed on part of the substrate. A bridge suspended over the channel houses a heater and a temperature sensor. The fluid temperature sensor is strategically placed to avoid thermal interference from the heater. A control circuit regulates the voltage applied to the heater based on the output from a bridge circuit that includes the temperature sensors. This design minimizes temperature differences between the heater and heat sensor, enhancing measurement accuracy.
