Title: Akihiro Ohoka: Innovator in Liquid Dispensing and Optical Character Recognition
Introduction
Akihiro Ohoka is a prominent inventor based in Osaka, Japan. He has made significant contributions to the fields of liquid dispensing and optical character recognition. With a total of 4 patents to his name, Ohoka continues to push the boundaries of innovation in his industry.
Latest Patents
One of his latest patents is an apparatus for automatically dispensing accurately a predetermined quantity of a liquid required to be stored at room temperature. This invention includes a syringe pump, a liquid tank, and a pump displacement mechanism for moving the syringe pump between the liquid tank and a container. The piston of the syringe pump is displaced by a piston displacement mechanism. Additionally, a weigher measures the weights of the tank and liquid in the tank, along with a draining system for draining the liquid of the liquid tank. Liquid is supplied to the liquid tank from a supply system, while a control device manages the displacement of the syringe pump and the piston, actuates the supply system and drainage system, and reads measurement output signals from the weigher.
Another notable patent is an optical character reading system. In this system, a sheet with printed characters or symbols is illuminated, and the characters are scanned using a two-dimensional photoelectric sensor. Output signals from the sensors are processed to read the characters through right and left frame detecting circuits. These circuits detect white/black patterns of frames formed on the sensor when the left and right sides of the characters extend beyond the sensor's range. A circuit combines the detected white/black patterns to provide recognition of the characters being scanned.
