Title: Eiichi Kotake: Innovator in Tachogenerator and Rotation Control Technology
Introduction
Eiichi Kotake is a notable inventor based in Fujieda, Japan. He has made significant contributions to the field of electrical engineering, particularly in the development of tachogenerators and rotation control devices. With a total of 2 patents to his name, Kotake's work has had a meaningful impact on technology.
Latest Patents
Kotate's latest patents include a "Tachogenerator having a magnetoresistance stator coil." This innovative tachogenerator features a magnetoresistance film coil that is formed on a stator surface along a circular path concentric with the rotor axis. The coil is designed with a spatially periodic structure, incorporating multiple spaced-apart lateral components that are series connected with longitudinal components. This design allows for the averaging of undesirable small voltage variations at the coil output terminals, enhancing performance.
Another significant patent is the "Rotation control device for information recording disc." This device is engineered to ensure that a disc, which contains recorded information and sync signals, rotates at a predetermined speed. The control device includes a generator that produces a signal with a frequency identical to that of the rotation signal output from a frequency generator. A control loop is established to compare the phase of the output from the signal generator with the rotation signal, thereby effectively controlling the motor drive.
