Title: Norio Nakagawa: Innovator in Projection Technology
Introduction
Norio Nakagawa is a prominent inventor based in Neyagawa, Japan. He has made significant contributions to the field of projection technology, holding a total of six patents. His innovative designs have enhanced the functionality and efficiency of image display apparatuses.
Latest Patents
One of Nakagawa's latest patents is a liquid crystal projector device. This device features an optical system that receives light from a lamp unit. The optical system includes a polarization beam splitter that extracts only the S wave from the light emitted by the lamp unit. Additionally, it has a latter stage slit plate that is in contact with the light incidence surface of the polarization beam splitter. This slit plate contains multiple slits that allow light to pass through. Furthermore, a former stage slit plate is positioned along the optical axis toward the lamp unit, with slits that overlap with those of the latter stage slit plate.
Another notable patent is for a projection type image display apparatus. This apparatus incorporates a first exhaust fan that primarily exhausts air from the light source unit and discharges it outside the apparatus. It also features a second exhaust fan that mainly exhausts air from the power supply unit. The design allows for efficient temperature reduction within the image display apparatus while minimizing fan noise. This innovation enables an increase in the power of the light source unit and contributes to the downsizing of the image display apparatus.
