Title: Innovations of Kunio Kitagawa
Introduction
Kunio Kitagawa is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of electromechanical transducers and printing mechanisms. With a total of 3 patents to his name, his work has had a considerable impact on technology.
Latest Patents
One of his latest patents is a mechanical amplification mechanism for electromechanical transducers. This invention involves a piezoelectric transducer for a printing pin of a dot-matrix or an armature of a relay that drives a mechanical amplification mechanism. The design features a base plate with a reference wall fixed to a frame, and an elongated piezoelectric transducer element that extends in the direction of its expansion. The lever arm is coupled to the transducer element and is fixed to the base plate by a fulcrum member. Additionally, a band spring is incorporated to enhance the functionality of the actuating element, which can be a printing pin or the moving contact of a relay.
Another significant patent is for a printing mechanism for dot matrix printers. This invention improves dot-type printers by employing a driving system that includes a variable-volume sealed container enclosing a pressure transmitting medium. Electrodes are placed within the medium, and the application of high voltage causes arc discharge, leading to the expansion of the medium and the sealed container. This expansion results in the linear movement of the printing pins or wires, enhancing the printing process.
