Abstract: An electronic apparatus includes a housing, a first filter, and a second filter. The housing includes a first intake port. The first filter is disposed on an outer side of the housing and covers the first intake port. The second filter includes a first part coarser than the first filter and covers the first filter from a side opposite to the first intake port.

Abstract: A hemofiltration device capable of surely performing highly-efficient hemofiltration. The hemofiltration device of the present invention is adapted to be implanted in a mammalian body for filtering blood, and includes a blood flow path layer having a blood flow path, a filtrate flow path layer having a filtrate flow path disposed along the blood flow path, and a filtration membrane interposed between the blood flow path layer and the filtrate flow path layer, for filtering the blood flowing through the blood flow path. A filtrate outlet of the filtrate flow path is provided at a position closer to a blood outlet than to a blood inlet of the blood flow path. The blood inlet, blood outlet, and filtrate outlet are provided only on one side or separately on opposite sides of a main body portion in the direction in which the layers are stacked.

Abstract: Disclosed is a refractory/heat insulating panel used in buildings and structures which must have a refractory performance. In the refractory/heat insulating panel (801), the mechanical strength and the fireproofing performance at the joint portions, which are weak portions in the panel, are increased by integrally forming inorganic boards (831) in the male and female joint portions (832, 836), filling a light-weight aggregate in the core material located at the male and female joint portions at a high density, or making the density of the core material at the joint portions higher than that at the center of the panel.
