摘要： PURPOSE:To absorb a radio wave at a predetermined frequency stably by forming air layers between concrete layers and between a concrete layer and a reflector. CONSTITUTION:The concrete panel 6 comprises two concrete layers 1, 2 and a reflector 5 made of a metal plate or metal foil wherein a plurality of protrusions 10 are provided integrally with one concrete layer between two concrete layers 1, 2 and the protrusions 10 are filled with a thermal insulating foamable material 7 in order to form an air layer 3. The space between the concrete layer 1 and the reflector 5 is filled with a normal thermal insulating material 8 in order to form an air layer 4. This structure can absorb the radio wave at a predetermined frequency stably thus facilitating the quality control at the time of production of the panel.

摘要： PURPOSE:To keep an appropriate strength without sacrifice of radio wave absorbing characteristics by providing a panel of concrete reinforced with nonconductive rods or steel rods and applying a radio wave absorbing material to the surface thereof. CONSTITUTION:When the concrete panel 1 is employed for the outer wall of a building, a concrete 4 reinforced with horizontal rods 2 and vertical rods 3 is formed by the concrete panel 1. A radio wave absorbing member 5, e.g. a ferrite plate or a concrete plate admixed with carbon, is then applied to the surface of the concrete panel 1. This concrete panel can keep an appropriate strength without sacrifice of radio wave absorbing characteristics.

摘要： PURPOSE:To electrolytically produce Al under stabilized conditions over a long period without decreasing purity of a formed metal or increasing a bed voltage by suppressing the cracking, breakage, etc., of a carbon block constituting a cathode carbon panel. CONSTITUTION:Plural carbon blocks b1, b2, b3,...bn are arranged in parallel in a hearth demarcated by a furnace shell (c) to constitute a cathode carbon panel. The square steel bars a1, a2, a3,...an piercing through the blocks b1, b2, b3,...bn in the longitudinal direction project from the end faces of the blocks b1, b2, b3,...bn and pass through square steel windows b1, d2, d3,...dn formed in the shell (c). The cross section moduli of the protrusions of the square steel bars a1 to an from the blocks b1 to bn at the ends for lateral bending are reduced, and the cross section moduli of the protrusions of the square steel bars ai to ai+1 from the blocks bi to bi+1 at the center for longitudinal bending are reduced.

摘要： PURPOSE:To obtain excellent radio-wave absorbing function by a method in which many radio-wave absorbing grains of capsules packed with water are dispersed in a hardened cement material to form a radio-wave absorber. CONSTITUTION:Radio-wave absorbing grains 1 of water-packed capsules of nylon or polyurethane are dispersed in 15-45vol.% into a hardened cement material 2 to form a flat structural plate. Both sides of the structural plate are covered with a water-impermeable sheet 3 such as polyethyleneterephthalate sheet. Excellent radio-wave absorbing function possessed by water can thus be provided.

摘要： PROBLEM TO BE SOLVED: To easily and firmly join existing and new tunnels together. SOLUTION: A cutting and reinforcing ring 6 is provided inside the skin plate 2 of a shield machine 1 in such a way as to be free to move back and forth in the excavating direction, and a ring driving jack 10 for pushing out the cutting and reinforcing ring 6 is provided on the ring 6. As a new tunnel T2 is excavated using the shield machine 1, the cutting and reinforcing ring 6 is pushed out by the ring driving jack 10 at a position a predetermined distance away from an existing tunnel T1, after which the cutting and reinforcing ring 6 is pushed out while being rotated by transmitting the driving force of a cutter 11. The segments of the existing tunnel T1 are cut using a cutting bit 7 to form openings so as to join the existing T1 and new T2 tunnels together.

摘要： PURPOSE:To dispense with a pipeline of another system for making fluid detour and other sites by blocking up a space between a temporary communicating pipe and an existing pipe member constituting an existing pipeline at the upstream side end of a closing division, and removing the member and disposing a new pipe member so as to construct a new pipeline. CONSTITUTION:It is determined that from an end on a side indicated by an arrow A to an end on a side indicated by an arrow B in an old sewage pipeline 11c is a pipeline renewal construction division SK. In order to smoothen pipeline renewal construction in the pipeline renewal construction division SK, a closing division HK where a passage of a sewage G is closed via a pipeline skeleton 12c of the old sewage pipeline 11c is previously planned. A shield driller 32 is advanced toward the arrow A direction. The shield driller 32 crushes and drills by a disk cutter the ground, the pipeline skeleton 12c or mortar filled in the pipeline skeleton 12c while advancing in the arrow A direction along a water flowing pipe 19. By this crushing and drilling, a new pipeline space 3a having the same diameter as that of an outer frame 33 can be formed.

摘要： PURPOSE:To certainly crush reinforcing bars inside of a building frame of an existing pipe at the time of wrecking, expansing and changing the existing pipe made of reinforced concrete. CONSTITUTION:A second cutter head 80 sharpened toward an inner peripheral margin 80a on the front surface side is provided inward of a first cutter head 10 sharpened toward an outer peripheral margin 10e on the front surface side, and a debris collecting region 25 is formed cylindrically in a shape to contract toward the rear side in the shield propelling direction by digging surfaces 10g, 80g of the first and second cutter heads 10, 80. Additionally, a wrecked matter transfer cavity 26 is provided between the first and second cutter heads 10, 80 in a form to communicate the debris collecting region 26 and a digging chamber 10c. A building frame 31 of an obsolete pipe 3 is further strongly crushed and treated by the wrecked matter transfer cavity 26 after primarily crushing it by rotational drive of the first and second cutter heads 10, 80 by way of taking it in the debris collecting region 25.
