A method of assembling a paper box, comprising a 1st step of carrying a paper box ( ) with unfolded both side wall members ( ) and ( ) into a clearance between a fixed stand ( ) and a guide member ( ) in the condition that the positions of folded parts ( ) and ( ) aligned with the positions of both outer end parts of the guide member ( ) at a folding station ( ) where the guide member ( ) is disposed with a slight clearance provided above the fixed stand ( ) and a clearance at both end parts thereof set equal to a clearance at the folded parts ( ) and ( ), a 2nd step of driving a folding member ( ) so as to fold both side wall members ( ) and ( ) to the inside with reference to the outer end part of the guide member ( ) in contact with the folded parts ( ) and ( ), and a 3rd step of extracting the paper box ( ) with bent both side wall members ( ) and ( ) from the folding station ( ) by holding the front side of the paper box ( ) in its moving direction.

An internal gear oil pump made of Al alloys having less mutual damage property and superior wear resistance is provided. The internal gear oil pump has a casing with a gear compartment, a drive gear, and a driven gear, all of which are the structural members of the internal gear oil pump. The casing is constituted of an Al-alloy casting. The drive gear and the driven gear are constituted of a hot plastic working material of Al&mdash;Si alloy powder. The hot plastic working material is constituted of an Al&mdash;Si alloy having a structure in which unit crystal phases are dispersed in a base matrix by 10 to 40 area percent. by the structural observation with an optical microscope, the unit. crystal phases being harder than the base matrix. The base matrix is constituted of an Al&mdash;Si alloy which contains, on weight basis, 10% to 18% Si, 4% to 8% Fe, 1% to 3% Ni, 1% to 3% Cr, and the balance being Al and incidental impurities. The alloy has a structure in which ultrafine grains of intermetallic compounds and Si are dispersed in the matrix. The unit crystal phases are constituted of an Al&mdash;Si alloy which contains, on weight basis, 25% to 40% Si, 1% to 3% Fe, 2% to 6% Ni, 0.3% to 2% Cr, and the balance being Al and incidental impurities. The alloy has a structure in which ultrafine grains of intermetallic compounds and Si, and primary Si crystal grains are dispersed in the matrix of the unit crystal phases.

Internal gear oil pump made of aluminum alloys

A box container having a bottom plate on which a rift is formed through one pair of opposite angles and a fold is running through each center of the other pair of opposite angles and having side plates each of which is connected in one piece to the periphery of said bottom plate, wherein the box container is pressed to be flat so as not to be bulky in transportation and storage and, in the case of assembling this box container, the bottom plate is unfolded to be flat along the folds which were provided on the bottom plate of said box container and, further, the whole of the bottom plate is fixed by sticking a quadrangular back plate thereto.
