Title: High pressure hose
Inventor: MATSUNAGA SHINJI
IPC: F16L33/20
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To shorten a joint part, and moreover make it compatible with the securing of sealing ability and durability. SOLUTION: In the joint 14 of a high pressure hose 10, a socket 18 is caulking formed at the first and the second caulked spot 24, 26 to diminish the wall thickness of the hose at each caulked spot for compressing and holding the hose 12 in a sandwiching manner. In the front and rear areas of the first caulked spot 24, since the hose 12 is radially and longitudinally enclosed by the socket 18 and a lock spot 20, the radial and longitudinal deformations of the hose are restrained, the their deformation degrees become extremely small. Thus since the first caulked spot 24 is therefore difficult to cause damage even in the case of a high change rate, the change rate higher than usual one, namely 46%, is given to the first caulked part 24 in order to secure high sealing ability, and the change rate of the second caulked spot 26 is set up to be somewhat lower, namely 40%, in order to avoid the damage of the hose.

Title: Reclamation using burned ash
Inventor: KANDA TORU
IPC: E02B3/18
Filed: 1993-07-21
Abstract: PURPOSE:To reduce construction cost and prevent the sinking of ground by arraying burned ash mixture packed in bags, of specified specific gravity, inside steel pie piles placed along periphery of a planned site for reclamation. CONSTITUTION:Steel-pipe piles 1 are placed along periphery of a planned site for reclamation, so that the revetment is made and the site is enclosed. Bubble is mixed to a mixture of incineration ash and water and small quantity of cement. The quantity of bubble added is so adjusted that specific gravity of the mixture becomes nearly 1. This air milk is then sealed in water impermeable bags. These air milk filled bags 2 are arrayed on sea surface within the revetment of steel-pipe piles. Air milk filled bags 2 are piled up on others, so that the air milk filled bags 2 in the lower layer reach to ground foundation 3 and the piling finally gets to a specified height. The air milk in water impermeable gas solidifies, becoming sufficient strength. Accordingly, because earth pressure to the steel-pipe piles is small and watertightness is not required of the revetment, the cost can be reduced, and besides, outflow of harmful matter is prevented. Since specific gravity of the air milk is the same as seawater, ground sinking is prevented.

Title: Preparation of glass fiber reinforced phenol resin foam
Inventor: SHINJIYOU IETSUGU
IPC: B29K61/04
Filed: 1982-10-14
Abstract: PURPOSE:To improve strength and wear resistance in a foam by a method wherein glass non-woven fabric bound by binder is impregnated with phenol resin solution, then heated to swell or dissolve the binder and expand the phenol resin solution. CONSTITUTION:Glass fiber web composed mainly of glass fiber is bound by the binder that can be swelled or dissolved by expandable phenol resin solution. Expandable phenol resin solution as obtained by mixing resol type phenol resin, hardener and expander is applied to and permeate through the glass fiber web obtained in this manner, and heat treatment is conducted under this state. Thus, the binder gradually swells and dissolves and the foaming agent also begins to foam. The glass fiber separates from swelled or dissolved binder with expansion of resin due to this foaming and is dispersed in layers and uniformly in the foamed resin. In addition, this heat treatment accelerates not only expansion but also hardening of resin to obtain the foam.
