With a total of 8 patents to his name, Koike's work has had a substantial impact on various industries.

Latest Patents

One of Koike's latest patents is a controller and control method for linear solenoid valves. This innovative controller executes a dither control that cyclically increases and decreases an exciting current in a linear solenoid valve, causing the spool of the valve to vibrate. The dither control includes a first dither control that vibrates the spool in a first dither cycle and a second dither control that vibrates the spool in a shorter second dither cycle. This method is particularly effective when the oil temperature of the hydraulic oil is between specified temperature ranges. Another patent involves calculating an average value of the exciting current within a period that includes a natural number multiple of the dither cycle. This allows for precise feedback control on the pulse width modulation signal, ensuring that the target value of the exciting current matches the average current value.
