Title: Innovations by Tomohiro Tamaoki
Introduction
Tomohiro Tamaoki is a prominent inventor based in Moriya, Japan. He has made significant contributions to the field of image forming technology, holding a total of 16 patents. His work primarily focuses on high-voltage power supplies and voltage generating devices.
Latest Patents
One of Tamaoki's latest patents is a high-voltage power supply for image forming apparatuses. This invention compares a detected output voltage generated by dividing a high-voltage output with a control value to feedback control the high-voltage output. It outputs a voltage that is applied to a member involved in image formation. The design includes a printed circuit board with a resistor connected to the high-voltage output side of the voltage dividing circuit. A slit is formed in the printed circuit board, which consists of a first portion extending across a straight line connecting the terminals of the resistor and a second portion that recedes from one of the terminals.
Another notable patent is a voltage generating device and image forming apparatus that outputs a developing voltage. In this invention, the pulse wave shape during positive amplitude differs from that during negative amplitude. Two switching regulators supply voltages to a bridge circuit for driving a transformer. The absolute value of the difference between the drive frequencies of the two regulators is configured to be not less than an invisible frequency, ensuring that banding is not recognized by humans.
