Latest Patents

**Design Process Recording.** This invention provides a way to record and connect stages of a design process. A recording unit stores design-work names, including external requirements, concept definitions, internal requirements, and detailed definitions. Another unit records relationships between these stages, helping document how requirements and definitions relate throughout the process.

**Image Forming Apparatus and Scanning Method.** This invention concerns an image-forming apparatus with multiple scanners, each using a rotary polygonal mirror. The system detects image-start reference signals and controls mirror rotation and phase. By correcting phase differences among the mirrors, it helps reduce image displacement in the sub-scanning direction.
