This invention relates to a coated article including a low-emissivity (low-E) coating. In certain example embodiments, the low-E coating is provided on a substrate (e.g., glass substrate) and includes at least first and second infrared (IR) reflecting layers (e.g., silver based layers) that are spaced apart by contact layers (e.g., NiCr based layers) and a dielectric layer of or including a material such as silicon nitride. In certain example embodiments, the coated article has a low visible transmission (e.g., no greater than 60%, more preferably no greater than about 55%, and most preferably no greater than about 50%).

The present invention provides an electromagnetic wave shielding method and window capable of bringing a conductive shielding layer into conduction to the outside without a connecting structure, and a manufacturing apparatus, a transport system, and a building construction each having the electromagnetic wave shielding window. In the invention, a conductive shielding layer having a visible light transmitting property is provided on a surface of window face members having an electrical insulating property and a visible light transmitting property, and the window face members provided with the conductive shielding layer are brought into close adhesion and thereby fixed to a conductive window frame member through an insulation layer provided to a rim portion, whereby electrostatic-capacitance coupling is induced between the conductive shielding layer and the window frame member. It leads to achieve the electromagnetic wave shielding effect without establishing a direct electrical connection for the conductive shielding layer.

The invention relates to a heavy electric radiation protection door. The door comprises a base with door hole, a door body and an electric control box, wherein the base above the door hole is provided with a main beam into which a lead screw driven by a motor is penetrated; multiple groups of horizontal pulleys are hung at the lower end of a nut engaged with the lead screw; rollers arranged at the upper ends of each group of horizontal pulleys are pressed on the surface of a horizontal guide rail arranged on the main beam in a sliding way; and all the lower ends of each group of horizontal pulleys are connected with the upper end of the door body. The door has a simple structure; stable and accurate running of the door body is realized by the lead screw and the horizontal pulley; opening or closing of the door body is realized by a frequency converter control motor; and the door has high automation level, is safe and reliable, and has a good radiation protection effect because barium sulfate concrete is filled in the door body.

In a double glazing where a pair of transparent glass sheets are arranged at an interval by having a spacer at the circumferential end portion and where a hollow layer sealed between the pair of glass sheets is formed, there is provided an electromagnetic absorption board used for wireless LAN, which is characterized in that the thickness of the glass sheet is in a range of 2.5-20 mm, that the thickness of the hollow layer is in a range of 2.5-15 mm, that at least one glass sheet of the pair of glass sheets is formed with a resistive film having a surface resistance (surface resistivity) in a range of 20Ω / □ to 2 kΩ / □, and that the resistive film is formed on a glass sheet side on the hollow layer side.

The present invention is related to an apparatus for irradiating products conveyed on a pallet, comprising a beam source (3) for producing a radiation beam, a shielding wall (4) encompassing an irradiation chamber (2) and a revolving cylindrical door (6) having a recess (8) for holding said pallet, for bringing said pallet in and out of the irradiation chamber (2) wherein said high-energy radiation beam is directed towards a lateral side of said revolving door (6), for irradiating said pallet in said recess (8), or brought before said recess (8).The present invention is also related to a process wherein a product pallet is brought into an irradiation chamber (2) through a revolving cylindrical door (6) having a recess (8), and irradiated while in said recess (8) or in front of said recess (8).

The invention relates to a civil air defense door. The civil air defense door comprises an inner door leaf and an outer door leaf. The inner door leaf and the outer door leaf are connected with each other through a slide connection mechanism, and a buffer layer is arranged between the inner door leaf and the outer door leaf. One side of the outer door leaf is of an arc-shaped structure, a plurality of metal fasteners and an up-down penetrating steel structure cylinder are arranged in the outer door leaf, compartments are filled with fireproof materials, and a plurality of ring-shaped grooves are formed in the peripheral surface of the cylinder at equal intervals. The metal fasteners are arranged on the ring-shaped grooves in a sleeving mode, each metal fastener comprises a fixing part and a mounting part, and each mounting part is formed by mutual welding of a plurality of rings. A first pre-buried piece is arranged on one side of the inner door leaf, a steel column is clamped through a clamping piece, a plurality of threaded holes are evenly formed in the steel column, and a steel plate is fixed to the steel column through screws to form a reinforcing plate. According to the civil air defense door, the weight of the door leaves is reduced, at the same time, the functions of fireproofing, explosion proofing and radiation proofing are achieved, the protection property is good and the door is not prone to being deformed and damaged, the reinforcing plate can be temporarily and additively mounted on the eve of a war, the mounting process is simple, the door can be mounted and used immediately, and the protection property is further improved.
