摘要:
The fracture-free paving block (1) comprises a cement block substrate (1-1) and a top solid layer (1-2), and is characterized in that the top layer is selected from a cured cement mortar layer and a tile-like layer firmly bonded to the substrate with cement mortar; the top layer is bonded to the block substrate with lateral margins (2) of 1 to 8 mm wide in horizontal distance (15) from the peripheral edges of the substrate; and the vertical distance (16) from the surface of the top layer to the peripheral edge of the substrate is 5 to 50 mm. The method for producing the paving block (1) having a tile-like top layer comprises applying adhesive cement mortar between the back of the top layer (1-2) and the upper surface of the substrate (1-1); placing the top layer on the substrate with the above-mentioned margins (2) of the substrate surface; and applying vibration and/or pressurization between the top layer and the substrate.

A dustproofing film (10) for a waveguide (4) is disclosed which is characterized by having an adhesive agent (12) applied to a peripheral edge area thereof and having formed in the area surrounded by the peripheral edge area a region not covered at all with any adhering substance and consequently allowing the electromagnetic wave to pass. A method for the production of a dustproofing film (10) for a waveguide (4) is disclosed which is characterized by cutting a prescribed shape (15) from a double-faced adhesive tape (20), removing a peel paper (13a) from one surface of the adhesive tape (20), attaching the part of the adhesive tape remaining (14) after the removal of the prescribed shape (15) to a film (11) formed of synthetic resin thereby forming a sheet material having formed within the area of the adhesive tape remaining after the removal of the prescribed shape a region (15) covered with neither an adhesive agent or a peel paper and consequently allowing the electromagnetic wave to pass, and cutting a prescribed shape from the sheet material around the periphery of the region for passage of the electromagnetic wave thereby forming around the periphery of the region for passage of the electromagnetic wave a peripheral edge region (14) having a peel paper (13b) attached thereto through the medium of an adhesive agent (12).

A mold (1) for cast-molding a slip under pressure is provided. The mold comprises a divisible casting mold (1) including at least two mold portions (8,9) to form a slip-depositing mold cavity (18) when mated together; a sealing material layer (11) attached onto at least the whole mating filter surface (16) of at least one mold portion to be mated; and a resilient material layer (10) attached onto one of the sealing material layer (11) and another mating filter surface (16), along slip-depositing divisible surfaces (12) of the filter layers (2); whereby the mold portions (8,9) mated together are provided with a resilient liquid-tight zone (14) between the mating filter surfaces (16). The mold is readily produced by coating at least the whole mating filter surfaces (16) of at least one mold portion (8,9) to be mated with a sealing compound; applying a releasing material between the mating mold portions (8,9), mating the mold portions, and hardening the sealing compound to provide a sealing material layer (11); and then bonding a resilient material sheet (10) onto one of the resulting sealing material layer (11) and another mating filter surface(16), along slip-depositing divisible surfaces (12) of the filter layers.

This invention relates to a gas-permeable porous body and production thereof by blending siliceous pagodite, limestone and clay in such a manner that SiO2 accounts for 70 to 88 wt.%, CaO 5 to 23 wt.% and Al2O3 5 to 15 wt.%, molding the mixture and sintering the mold at 1,000°C or above. This porous body has an extremely uniform pore diameter and high gas-permeability and is used for a filter or an aeration member or for a mold for pressure casting. This invention relates also to a pressure casting mold having drain paths (5, 5') which are formed near the boundary surfaces between surface layers (50) and support layers (60). The surface layer (50) is made of the gas-permeable porous body described above. This mold makes it possible to release smoothly a thickened portion.
