Title: Nobuhisa Kato: Patented Innovations in Image Recording and Circuit Design.

Introduction

Nobuhisa Kato is an inventor associated with Kanagawa, Japan, and Fuji Xerox Co., Ltd. His work includes inventions in digital circuit design and halftone image recording. He is credited with 6 patents.

Latest Patents

Kato’s listed patents include a coincidence circuit that detects when n-bit binary input data matches the current value of an n-bit counter. The design uses circuits to check whether each input bit set to one corresponds to a counter bit also set to one. A first-coincidence detector identifies when all such bits match, using inverter and NOR-gate components alongside an OR gate and latch circuit.

Another patent concerns converting halftone image gradation data into bit-train data for an image recording apparatus. For gradations above a threshold, the conversion table intermittently omits bits after outputting the bit sequence associated with the threshold. A second section converts the bit train into a corresponding pulse train, which controls a thermal-head heating element. The design regulates the element’s temperature below a predetermined level.

Career Highlights

Kato’s patents reflect technical contributions to coincidence detection and thermal-head image recording. These inventions address circuit logic and the control of gradation in recorded halftone images.
