Title: Tokihiko Kobata: Innovator in Pressure Measurement Technologies
Introduction
Tokihiko Kobata is a notable inventor based in Tsukuba, Japan. He has made significant contributions to the field of pressure measurement technologies, holding a total of 2 patents. His work focuses on innovative methods and apparatuses that enhance the accuracy and efficiency of pressure gauge calibration.
Latest Patents
One of his latest patents is the "Static Expansion Method." This method involves expanding a volume of a testing gas from V to V+V between a second chamber connected to an upstream side of a measurement chamber and a first chamber. The first chamber communicates with the second chamber via a first valve, while the second chamber connects to the measurement chamber through a second valve and an orifice or porous plug. This setup allows the testing gas to flow from the first chamber to the measurement chamber only through the orifice or porous plug when the first valve is opened and the second valve is closed.
Another significant patent is the "Pressure Gauge Calibration Apparatus." This apparatus is designed to be user-friendly and utilizes a pressure gauge as a standard device. It is not influenced by the order of calibration pressure points or the duration of pressure holding time. The apparatus includes a pressure gauge calibrated in advance, a pressure generation control device, a shut-off valve, and a measurement control unit. This innovative design ensures accurate calibration at each pressure point.
