Latest Patents
One of his latest patents is a solenoid valve drive system. This system includes a step-up circuit that produces a first high voltage using a switching device to control the current supply from a battery to a step-up coil. It efficiently stores this high voltage in a first capacitor for initial high-voltage driving of a solenoid valve. Additionally, it features a second capacitor and a discriminating circuit that determines the charge voltage level of the second capacitor. The system can produce two types of high voltages without enlarging the circuit size. Another significant patent is a method and apparatus for high-speed driving of an electromagnetic load. This apparatus applies a high voltage at the initial driving stage and then a constant hold current. It includes a switch for supplying high-voltage energy from a capacitor and a control circuit that responds to an electric signal for starting the driving process. This configuration allows for optimum timing in switching from high-voltage application to hold mode operation.
