Abstract: PURPOSE: To make it possible to impart gas and oil-impermeable surface characteristics to a polymer film like polyethylene by coating film with an appropriate silane compound and causing a crosslinking action in the compound so that the physical adsorption and adhesion takes place. CONSTITUTION: A siloxane polymer is prepared by hydrolyzing a silane monomer in an aqueous alcohol solution. The hydrolysate is left alone at 25 deg.C for about 24 hours to equilibrate an oligomerlike siloxane structure, and the aqueous alcohol solution containing the oligomerlike siloxane structure is applied to the surface of a polymer film. Further, alcohol and moisture are vaporized by drying the coat to complete the formation of the Si-O-Si bonding of the polymer coating. When the siloxane polymer or copolymer has a double bond, the siloxane polymer can be grafted on the surface of a film by crosslinking a routinely promoted peroxide. Prior to the siloxane coating, a polyolefin film is subjected to a corona discharge treatment to upgrade the adhesive properties of the coating.

Title: Pressure fatigue testing device
Inventor: NARA YASUAKI
IPC: G01N3/34
Filed: 1991-03-08
Abstract: PURPOSE:To obtain a pressure fatigue testing device for confirming the durability of an equipment receiving fluctuating pressure that can operate at high speed, in small size, and with less noise and less power consumption. CONSTITUTION:By reciprocating a piston 2 inside a cylinder 1 between B and C making a reference of a position A, repeated fluctuating pressure can be obtained inside the cylinder. Since the fluctuating pressure is determined by the volume inside the cylinder 1 and the stroke volume of the piston 2, the control of the fluctuating pressure can be easily carried out by opening a valve 3 and by constituting a chamber 4 in such a way that the volume thereof can be variable. Since the pressure fluctuating cycle can be quickened, the period for a pressure fatigue test can be significantly reduced, and also since the test can be carried out only by compressing and expanding closed air, a compact pressure fatigue testing device with less noise and less power consumption can be obtained.

Title: Reinforcing material and resin molding containing the same
Inventor: HIRANO TATSUMI
IPC: B29C70/68
Filed: 1995-03-02
Abstract: PURPOSE: To obtain a reinforcing material which is excellent in dimensional stability and adhesion to a polyolefin resin and has a fused layer having the evenness of thickness by coating a metal substrate with a fusible coating composition comprising a specific polyester resin and a specific compound and baking the coating to form a fused layer. CONSTITUTION: A metal substrate is coated with a fusible coating composition obtained by dissolving a polyester resin having 3-50 hydroxyl groups per molecule and a diisocyanate compound in an organic solvent. The resulting coating is baked to form a fused layer, thereby giving a reinforcing material. Part of the hydroxyl groups of the polyester resin react with NCO groups during baking to form urethane bonds, with which the polyester is crosslinked in some degree. This crosslinking heightens the melting point of the layer to diminish the surface tank of the reinforcing material at ordinary temp. and thus heighten the efficiency of resin molding production. Forming a resin layer consisting mainly of a polyolefin resin on the periphery of this reinforcing material gives a resin molding having excellent dimensional stability.
