Solid state neutron detection utilizing gadolinium as a neutron absorber is described. The chamber has a front plate and a back plate located on opposite sides of the chamber, and each of the front plate and the back plate has a first through hole and a plurality of second through hole formed therein. When swinging the swinging member, the user can access the medium feed section for removing the jammed medium. The instance variable of an object in the inline-expanded method invocation is scalarized, and dead code elimination is performed for the execution program, to which an inline-expansion and a scalarization is performed. This generator creates high voltage DC electricity. The method includes arranging a plurality of first reinforcing fibers in a transverse direction and attaching a permeable transport web of staple fibers to the first reinforcing fibers such that the portion of the first reinforcing fibers oriented in the direction transverse comprises at least 30% of a volume of materials comprising the reinforcing structure.
