Title: Tetsuroh Kawai: Innovator in Flow Control and Magnetic Head Technology
Introduction
Tetsuroh Kawai is a notable inventor based in Kumagaya, Japan. He has made significant contributions to the fields of flow control devices and composite magnetic heads. With a total of 2 patents to his name, Kawai continues to push the boundaries of innovation in his field.
Latest Patents
Kawai's latest patents include a flow control device that utilizes a comparator to output a first control voltage based on the comparison of an instruction value signal of the flow volume and a sensor output signal. This device features a feedback current generator that produces a feedback current according to the difference between the sensor output signal and the instruction value signal. Additionally, a feed forward current generator creates a feed forward current based on the instruction value signal. The synthesis unit then generates a second control voltage by adding the feedback voltage to a voltage derived from the sum of the feedback and feed forward currents. The valve unit is controlled according to these two control voltages. Another patent involves a composite magnetic head that includes a slider plate and a back board, where a front magnetic core is fixed to the slider plate, forming a transducer element with the back yoke and coil layer.
