Title: Hisakazu Ohkawara: Innovator in Image Forming Technology
Introduction
Hisakazu Ohkawara is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of image forming technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and quality of image formation processes.
Latest Patents
Ohkawara's latest patents include a writing controlling device and a color image forming apparatus. The writing controlling device is designed for an image forming apparatus and features a time lag detecting device. This device detects the time lag between a synchronization signal and a mark signal generated by a mark sensor. It outputs a white line insertion value based on the detected time lag. Additionally, a reconfiguration device adjusts the white line insertion value and a write timing setting value, optimizing the writing start position in a sub-scanning direction.
The color image forming apparatus patent addresses magnification correction of an image. This is achieved by altering the cycle time of an optional pixel until a calculated phase adjustment amount exceeds a preset specified value. Once this threshold is surpassed, magnification correction is performed by changing the frequency of the image signal. This innovative approach reduces the frequency of image forming operation suspensions during magnification corrections.
