摘要： The present invention relates to a porous material, the pores of the porous material are uniformly distributed. The uniform distribution of the pores means that the pores are evenly distributed at any unit-level volume of the porous material; and the elastic modulus of the porous material is reduced by 10-99% compared to that of the raw material used to make the porous material. This kind of porous material ensures the uniformity in its various properties. It is a porous material with excellent performance and quality. Its uniformity also ensures that its elastic modulus can be effectively reduced to meet multiple purposes.

摘要： The prevent invention addresses the problem of providing a multilayer filter medium for a filter having low pressure loss and high collection efficiency, a method for producing the same, and an air filter not only having low pressure loss and high collection efficiency but also being excellent in pleatability and wind-pressure deformation resistance. The multilayer filter medium for a filter as a means for resolution is obtained by laminating a wet-laid nonwoven fabric layer (2) on a wet-laid nonwoven fabric layer (1). The wet-laid nonwoven fabric layer (1) includes a nanofiber A having a single-fiber diameter within a range of 200 to 800 nm and a fiber length within a range of 0.4 to 0.7 mm, a fiber B having a greater single-fiber diameter than the nanofiber A, and a binder fiber C. The wet-laid nonwoven fabric layer (2) includes a nanofiber A having a single-fiber diameter within a range of 200 to 800 nm and a fiber length within a range of 0.4 to 0.7 mm, a fiber B having a greater single-fiber diameter than the nanofiber A, and a binder fiber C, the weight proportion of the nanofiber fiber A being greater than in the wet-laid nonwoven fabric layer (1).

摘要： [Object]
To suppress variations in the filling rate of molten resin in a cavity and suppress the occurrence of burrs in the opening of a filter portion.
[Solution]
Four gates 18 are provided in one end surface 14a of the inner cylinder cavity section 14 of an injection molding die 10 along the circumferential direction of an inner cylinder cavity section 14. The gates 18 are disposed in intermediate parts between a first central line 20 and a second central line 21 when the first central line 20 passes through the center of the inner cylinder cavity section 14 in parallel to the X-axis and the second central line 21 passes through the center of the inner cylinder cavity section 14 in parallel to the Y-axis on an X-Y plane orthogonal to a central axis 17 of the inner cylinder cavity section 14. The gates 18 are opened in the positions in which the filling rate is apt to reduce in the filter portion cavity section 16 and the gates 18 are not opened in the positions in which the filling rate is apt to increase in the filter portion cavity section 16.
