Abstract: A general-purpose electromagnetic wave shielding interior material having an excellent electromagnetic wave shielding property as well as a good interior finishing property is disclosed. A protective film made of resin is stuck onto one side surface of an electromagnetic wave shielding metal foil, and an incombustible paper sheet is stuck onto the other side surface of the same electromagnetic wave shielding foil to form a laminated sheet having the desired properties. Preferably, the electromagnetic wave shielding metal foil is exposed from the peripheral edge portion of the laminated sheet, and an overlapping margin is reserved at the peripheral edge portion of the laminated sheet.
Abstract: A novel method for joining edge portions of electromagnetic wave shielding members is proposed. A joiner is prepared by solder-plating a surface of a narrow strip of electromagnetic wave shielding material of a metal foil or a metal sheet. The respective edge portions of adjacent electromagnetic wave shielding members made of metal sheets or metal foils are butted against each other. The solder-plated surface of the prepared joiner is superposed on the respective abutting edge portions of the electromagnetic wave shielding members. Thereafter, while the joiner is being pressed against the shielding members by a heater, the joiner is solder-welded to both of the electromagnetic wave shielding members via the solder-plated layer.
Abstract: A tile-mount for mounting tiles on a wall surface. The mount plate has at least one projection extending in a longitudinal direction thereof and base portions. The top surface of the projection has vertically spaced engaging members, and, each of tiles has an engaging portion which engages with the engaging members, and when the base portions are connected to a surface of a foundation, a longitudinally extending passageway is formed between the foundation and the mount plate, which passageway allows rain water or condensation to be exhausted therefrom.
Abstract: A heat exchanging element for use in a rotary-type counter-current heat exchanger is provided. The heat exchanging element comprises a gathering member composed of natural fiber, especially coconut fiber. And a rotary-type counter-current heat exchanger is provided. The heat exchanger comprises a casing, a rotary frame rotatably supported by the casing, the rotary frame having a shaft, a pair of rotor rims maintaining a predetermined distance in an axial direction of the shaft and a plurality of rotor spokes, and the heat exchanging element accommodated in the rotary frame.
