Abstract:
The present invention provides a tank including an O-ring 34 between a cylindrical mouth portion 18, which is formed in a resin liner 12 forming a tank body which is to be filled with gas, and a ferrule member 20 which is mounted on an inner peripheral side of the mouth portion 18. An insert ring 36 which is insert-molded at the time of molding the resin liner 12 is provided within the mouth portion 18. The insert ring 36 includes a plurality of communication holes 38 which communicate between the inner peripheral side and an outer peripheral side thereof.
Abstract:
In at least one of flow distribution areas 35 provided on a separator 15, plurality of first projections 46 formed in a region corresponding to a first section (parted regions 32a and 32c) of a center area (including parted regions 32a through 32c) having a relatively high flow rate of a first fluid (refrigerant) are designed to have a larger diameter of a cross section than plurality of first projections 46 formed in a region corresponding to a second section (parted region 32b) of the center area having a relatively low flow rate of the first fluid. This arrangement effectively attains a substantially uniform flow rate distribution of a fluid in a fluid flow path formed on a separator, which is configured to have concavo-convex structures formed in a mutually reversed relation on two opposed sides thereof.
Abstract:
A toner includes toner particles containing at least binder resin and colorant. The toner particles contain a large-sized toner particle group of particles and a small-sized toner particle group of particles having a volume average particle size smaller than that of the large-sized toner particle group. In the toner, a volume average particle size D50v is 4 μm to 8 μm at 50% in accumulated volume counted from a large particle-side in accumulated volume distribution of entire toner particles; a content of toner particles contained in a toner particle group having a volume average particle size of 7 μm or more is 24% to 47% by volume based on the entire toner particles; and a content of toner particles contained in a toner particle group having a number average particle size of 5 μm or less is 10% to 50% by number or less based on the entire toner particles.
