Title: Tomoko Ogawa: Innovator in Image Recording Technology

Introduction

Tomoko Ogawa is a prominent inventor based in Tokyo, Japan. She has made significant contributions to the field of image recording technology, holding a total of 4 patents. Her innovative work has advanced the capabilities of image recording apparatuses and laser technology.

Latest Patents

One of her latest patents is an image recording apparatus designed for electrostatically forming a latent image on an image carrier. This apparatus operates by driving optics in response to multi-level image data. Before initiating an actual image recording operation, a latent image in the form of a test pattern with multiple tones is created on the image carrier using pulse width modulation. A correction table for image data is generated based on the sensed surface potentials of the test pattern. The semiconductor laser included in the optics is driven to maintain a constant relationship between the tone data and the latent image potential.

Another notable patent is for a metal vapor laser apparatus and method. This apparatus features a gas supply device that provides at least two types of gases to the laser container, controlled individually. One gas is selected from molecular gases, such as hydrogen, while the other is from rare gases, like neon. By adjusting the mixture ratio of these gases, the laser beam output is achieved efficiently. The molecular gas is supplied when a metal lump, such as copper, in the container is melting.
