摘要： PURPOSE:To produce a glass product which is provided with continuous pores and capable of permeating liquid by sticking sol consisting of metallic alkoxide as a principal raw material to the periphery of the skeleton of a combustible or soluble structural body and allowing it to gel, and sintering it after removing the structural body. CONSTITUTION:Sol consisting of metallic alkoxide as a principal raw material is stuck to the peripheries of skeletons 4 of a structural body 2 at prescribed thickness and allowed to gel. The structural body 2 stuck or filled with the gelled raw material 10 of glass is dried. After drying, the structural body 2 is burned by heating it or removed by eluting it with a suitable solvent. This dried gel wherein the structural body 2 is removed therefrom is sintered. Thereby a porous glass product in which continuous holes are formed in the removal parts of the structural body 2 is obtained.

CONSTITUTION:The gob 36 cut to a specified size is guided by the inner holes 18 and 22 of an upper barrel 12 and a lower barrel 14, and introduced into a scoop 26. At this time, a funnel 20 forming the inner hole 18 is formed by a porous member 46, and a pressure fluid is supplied from a supply pipe 54 and injected from the open cell 40 of the porous member 46 through a supply hole 52 and a continuous space 50. In addition, the skeleton 38 is itself forming a continuous skeletal system as a whole in the porous member 46 is hollowed, a ceramic structure 42 wherein the continuous open cell 40 is formed in the skeleton 38 is arranged in a casting cavity, a molten metal is infiltrated into the skeleton 38 to integrate a casting metal 44 and the ceramic structure 42, and the open cell 40 is opened by grinding on the inner and outer peripheries.

摘要： PURPOSE:To promote the cost down improving workability of manufacture, by providing a supply flow path communicating with plural holes and supplying pressure fluid to these air holes so as to eliminate an afterprocess of machining an injection hole. CONSTITUTION:A conveying base bed 10 respectively constitutes injection holes 16 opened in a guide surface 14 by air holes 32 while a supply passage 17 supplying pressure fluid, introduced from the outside through an air supply hole by space 34, to the injection hole 16. Accordingly, the injection hole 16 such as in the above, being constituted of the air holes 32 formed in a pillar-shaped framework part 30 of a ceramic structure 18, can be very easily formed simultaneously with casting of the conveying base bed 10. Especially as compared with providing the injection hole such as described to be drilled by a conventional afterprocess of machining, the rapid improvement of workability of manufacture and its cost can be effectively promoted.

摘要： PURPOSE:To design omission of hole drilling in a later process on a faceplate by constituting outlet holes for pressurized gas on the faceplate with holes in a porous ceramic so that holes of a minute diameter are uniformly distributed at any required position. CONSTITUTION:Forming a squarely recessed groove 12 on a chuck body 10, a coil 14 is housed and arranged in it. A gas supply passage 42 is drilled in a faceplate 22 so that a workpiece can be removed by blowing pressurized gas under a condition of the coil 14 not being energized. Constituting specified portions of a disk body 26 and a magnetic pole portion 28 with a porous material 32, they are made to be exposed at a loading surface 30. With this constitution, it is possible to set gas outlet holes of a minute diameter with a uniform distribution density at any required position on the loading surface 30 regardless of the materials of the surface plate 22. With this constitution, a later process for forming gas outlet holes is not necessary. Since only the gas supply passage 42 of a relatively large diameter has to be drilled, manufacture at a low cost is possible.

摘要： PURPOSE:To improve load capacity and bearing rigidity and reduce manufacturing cost by making gas blow into an inner hole of a housing through a porous member made by mixing a specified matrix material into gaps in a skeleton made of a ceramic porous body. CONSTITUTION:An inner hole 12 is bored through a housing 10 provided with a gas supply passage 38 and a gas discharge passage 29. A shaft member 20 is inserted in the inner hole 20 with its both longitudinal ends provided with lid members 18 and 16 so as to form an integral body. Further, porous embers 28 are arranged to form an integral body consisting of a cylinder for covering the inner circumferential surface of the inner hole 12 and disks for covering the inner surface of the lid members 16 and 18. Pressure gas is blown out via the air supply passage 38 and a space 40 serving as a gas reservoir. The porous member 28 is constituted by mixing casting metal into cells in a ceramic porous body so as to form blowout holes of a fine diameter in an effectively distributed condition. As a result, load capacity and bearing rigidity are improved to cope with a higher rpm and the manufacturing cost can be reduced.

摘要： PURPOSE:To make possible the thorough inoculation in a casting mold by installing a porous ceramic body imposed with a prescribed inoculant into a molten metal passage of the casting mold so as to part the passage. CONSTITUTION:An inoculating device 12 is constituted by containing the granular inoculant 8 into the recess of a ceramic foam 2. Such device 12 is so set in a pouring basin 18 of a runner 16 which is the molten metal passage of the casting mole 14 as to part the passage. The melted inoculant passes through the pores of an inoculating core 2 and flows into the mold 14 when the molten metal 22 of a high temp. flows into the mold. The inoculation by this method is executed in the place nearest the part in the casting mold 14 where the product is going to solidify in the above-mentioned manner and the possibility of self-annihilation is eliminated. The amt. of the inoculant to be added is considerably decreased.

摘要： A fluid-permeable article which permits fluid to pass therethrough includes a porous ceramic structure having a multiplicity of hollow members made of ceramic material which are concatenated with each other to form a framework having a continuous capillary passageway system. A continuous space is formed outside of the framework and is defined by the outer surfaces of the hollow members. A continuous matrix material fills the continuous space outside of the framework and cooperates with the porous ceramic structure to provide an integral composite structure consisting of the ceramic material and the matrix material. The continuous passageway system is open in at least a portion of the exposed surfaces of the article and permits fluids to pass therethrough.
