  • Publication number: 20230150020
    Abstract: A method for manufacturing a sintered product from a three-dimensional object as a solution includes: a preparation step S11, a degreasing step S12, and a sintering step S13. In S11, a multilayer made of an ink containing inorganic particles and an organic material is formed to prepare a three-dimensional object. S12 includes: a first degreasing step of heating the three-dimensional object under an inert gas atmosphere at a first average degreasing temperature (T1) for a first heating time to degrease the organic material; and a second degreasing step of heating the three-dimensional object degreased in the first degreasing step, under an inert gas atmosphere at a second average degreasing temperature (T2) higher than Ti for a second heating time to degrease the organic material. In S13, the three-dimensional object degreased in the second degreasing step is sintered at an average sintering temperature higher than T2 to obtain a sintered product.

  • Patent number: 6891140
    Abstract: A sintering furnace for sintering an object to be sintered formed of ceramics, fine ceramic materials, etc. to produce a sintered object and a method therefor. An insulating wall (28) and an inner shell (25) define a sintering chamber (16) for sintering an object to be sintered (10). Thermal equilibrium is maintained between the inner shell (25) and the object to be sintered (10), and the object to be sintered (10) is completely pseudo-adiabatically isolated to achieve more uniform and small energy consuming sintering. The thickness of the insulating wall (28) increases gradually from an inlet (20) toward an outlet (21). The object to be sintered (10) is fed by a carriage provided in a sintering furnace from the inlet (20) to the outlet (21) in the sintering chamber (16). Thereby, a temperature distribution corresponding to a plurality of processes can be easily formed in one furnace to sinter continuously the object to be sintered (10) in the furnace.

  • Patent number: 4989301
    Abstract: The drawing device inserts a warp into a heald hole of a heald and between reed dents of a reed. The device comprises an air guide including an air passage having an entrance and an exit, an air stream generating mechanism operationally connected with the air passage for generating an air stream running from the entrance toward the exit in the air passage, a heald feeding and moving mechanism for feeding one heald just in front of the entrance of the air passage and for arranging the heald so that the heald hold of the heald may be opposite to the entrance, and a warp feeding mechanism for feeding and arranging a warp just in front of the heald hole of the heald arranged just in front of the entrance of the air passage.
