Title: Hidetoshi Ryu: Innovator in Interface Circuits and Pump Control Methods
Introduction
Hidetoshi Ryu is a notable inventor based in Fukuoka, Japan. He has made significant contributions to the fields of interface circuits and pump control methods. With a total of two patents to his name, Ryu's work showcases his expertise and innovative spirit.
Latest Patents
Ryu's latest patents include an interface circuit and a pump-off control method for pump jacks. The interface circuit features a general-purpose CPU designed to transmit a clock to a serial encoder, enabling bidirectional serial communication with clock synchronization. This CPU is also responsible for transmitting and receiving data from the serial encoder. An additional circuit detects the start bit of the reception data, allowing the CPU to count the number of bits in response to a detection signal. The CPU ceases clock transmission upon completing the count of a predetermined number of bits.
The pump-off control method involves detecting the speed and instantaneous current of an induction motor. It calculates the average value of the secondary current during the down stroke of the pump jack cycle. By comparing this calculated average with a reference value, the method can detect occurrences of pump-off, ensuring efficient operation.
