Title: Regenerative body support mechanism in regenerative burner
Inventor: SHIZUKUISHI SHIN
IPC: F23D14/66
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To readily conduct maintenance by packing a large diameter regenerative body in a high temperature side and a small diameter regenerative body in a low temperature side, providing a plate-like partitioning wall between these packed layers and providing a cylindrical partitioning wall to the large diameter packed layer. SOLUTION: A cylindrical partitioning wall 16 which matches with the periphery of a fuel supply pipe 6 or the like is provided to a packed layer of a large diameter regenerative body 2b. The cylindrical partitioning wall 16 is formed between a plate-like partitioning wall 10 and a high temperature side support member 5 without a gap. These partitioning walls 10, 16 can be made of ceramic or the like of high heat resisting material. Accordingly, the large diameter regenerative body 2b is kept at a given position by the plate-like partitioning wall 10, the cylindrical partitioning wall 16 and the high temperature side support member 5, and therefore the fuel supply pipe 6 or the like is not required to be inserted into an inserting port 9 of the support member 5 at the high temperature side.  Thus, the large diameter regenerative body 2b is prevented from flowing into a packed layer 3s of a small diameter regenerative body through an inserting port 11 of the plate-like partitioning wall 10, and from flowing outside of a burner through the inserting port 9 of the support member 5.

Title: Color display device
Inventor: UCHIDA TATSUAKI
IPC: G09F9/00
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption and to enhance the efficiency of light utilization by enlarging extracted monochromatic light so as to visually recognize wide angle of visibility by a slit for selecting and extracting light which makes only light having nearly single wavelength pass through among spectra having respective wavelength. SOLUTION: The light which is transmitted through a prism 3 so as to be spectrally split and so as to have a specified wavelength goes toward the slit 4, and the light having a wavelength component reaching a slit gap part 4a is emitted outside the slit. When the width of the part 4a is set to width by which only light having nearly a single color component passes through, only certain light passing through the part 4a having the single color component can be transmitted through the part 4a. This monochromatic light is enlarged by the micro lens 5a of a convex lens 5. Thus, the monochromatic light is displayed with respect to the large visual field, so that a pixel can be displayed. That is, the dependency of the angle of visibility of the wavelength is compensated by utilizing the lens 5, so that the same picture can be obtained with respect to the wide angle of visibility.
