Title: Photocatalyst
Inventor: IWASHIMIZU MASAKATSU
IPC: B01J32/00
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To improve the photodecomposition effect of a harmful substance and to also enhance deodorizing function by providing piercing voids to a substrate and irradiating the rear surface of a photocatalyst carrier or the surfaces of its layers on and after the second layer thereof with light through the piercing voids and by utilizing the reflection on the surface of the substrate. SOLUTION: Piercing voids 2 are provided to a substrate 1 for supporting a photocatalyst. When the single surface of the photocatalyst 3 formed on the substrate 1 is irradiated with light, light passes through the piercing voids 2 toward the back side of the photocatalyst 3 without being perfectly blocked. Therefore, when the first layer of the photocatalyst is irradiated with light in such state that the photocatalyst 3 is laminated, the second layer thereof is also irradiated with light and, in the same way, the third and fourth layers thereof are successively irradiated with light. By providing the piercing voids 2 to the substrate 1 for supporting the photocatalyst, the shade of light is largely eliminated and the photodecomposition of a harmful substance acts effectively and deodorizing function, or the like, can also be.

Title: Phenolic resin foam composite panel
Inventor: MIDORIKAWA ICHIRO
IPC: B32B27/42
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain a lightweight panel having a high surface strength, a fireproofness and high heat insulating properties by a method wherein an inorganic molded body is laminated on at least one side of a phenolic resin foam panel, the bulk density and a non-interconnecting cell rate of which are respectively specified. SOLUTION: The density of a phenolic resin foam is 10-300 kg/m<3> , preferably 15-200 kg/m<3> . If the density exceeds 300 kg/m<3> , the feature as the lightweight properties lessens and, at the same time, the heat insulating properties become low. If its density is below 10 kg/m<3> , the mechanical strength such as a compressive strength and the like become small and a resultant panel easily tends to break during its handling. The non-interconnecting cell percent of the phenolic resin foam is 70% or more, preferably 80% or more.  If the non-interconnecting cell percent is below 70%, the water absorption properties of the panel become larger and, under the condition that defects such as cracks or the like develop in some part of a laminated inorganic molded body, the phenolic resin foam absorbs water through those defect portions, resulting in developing the possibility for lowering the heat insulating properties of the panel.

Abstract: PURPOSE:To make the difference of optical path small and to prevent diffraction efficiency from lowering by allowing reflected light beam from an optical information recording medium to pass through a substrate which is provided with diffraction gratings having equal pitch on both surface and back face and has higher refractive index than that of the diffraction grating. CONSTITUTION:Reflected light beam 23 is made incident on the diffraction grating 27a on the surface side of a dual grating 26 through a detection lens 25 and separated to two light beams, zeroth order light T and 1st order light K, which pass the substrate 27 to be emitted to the outside by the diffraction grating 27b on the back face side. Since the refractive index of the substrate 27 is set to be larger than that of the gratings 27a and 27b, the zeroth order light T and the 1st order light K trace an optical path shown by a continuous line and the difference of optical path between the light T and the light K is made small. In the case of arranging a photodetector 28 which respectively detects the light T and the light K on the same surface, the photodetector of large area need not be arranged on a 1st order light side.

Abstract: PURPOSE:To prevent the generation and adhesion of acid ammonium sulfate in and to machines and instruments arranged on the downstream side of a desulfurization device by a method wherein an exhaust combustion gas is supplied to a burner so as to perform a low O2 and low temperature combustion operation. CONSTITUTION:Fuel is burned with the primary air supply A1 from an inner cylinder 20 having the burner 17 at the center thereof to thereby produce flame F.

Further, secondary air A2 and tertiary air A3 are also supplied from the annular clearance between the cylinders 20 and 21 and from the outermost periphery of the device, respectively, but these airs A2 and A3 are isolated from the flame by the exhaust combustion gas G. Consequently, the amount of generation of SO3 is reduced to a great degree and the blockade and corrosion of the devices arranged on the downstream side of the desulfurization device are prevented.
