Title: Lead frame for ic
Inventor: NIKAIDO HIDEYASU
IPC: H01L23/50
Filed: 1986-10-29
Abstract: PURPOSE:To effectively suppress the diffusion of a chemical element constituting a lead frame material to an Al film and to reduce a manufacturing cost by forming a refractory metal layer between a lead material of a bonding part and the Al film. CONSTITUTION:A refractory metal layer is formed between a lead material of a wire-bonding part and an Al film. The refractory metal refers to a metal whose melting point is higher than 1700  deg.C; e.g., Pt (1774  deg.C), Ti (1800  deg.C), Cr (1905  deg.C) Nb (2415 deg.C), Mo (2620  deg.C), Ta (2996  deg.C), etc., can be enumerated. The reason why this kind of refractory metal is lair between the lead material and the Al film is to suppress the diffusion of Cu (1083 deg.C), Fe (1535  deg.C), Ni (1450  deg.C), etc., from the lead material; the effect becomes big with the increase in the melting point. Because the film thickness of the Al film can be made thin through this constitution, it is possible to reduce a manufacturing cost.

Title: Exhaust gas recirculation system
Inventor: KUZUTANI YOSHIFUMI
IPC: F01P9/02
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To heighten fresh air charging efficiency and to prevent water, condensed at the time of an EGR cooler cooling exhaust gas returned to an intake system of an internal combustion engine, from being sucked into a combustion chamber. SOLUTION: This exhaust gas recirculation system is provided with a water spraying means 6 for spraying water in an intake pipe 15 of an internal combustion engine 1, and a water supply means 7 for supplying water to the water spraying means 6. Water sprayed in the intake pipe 15 and diffused toward the internal combustion engine 1 is vaporized taking heat of vaporization from intake air or returned exhaust gas to cool the intake air or exhaust gas. With this constitution, even though the cooling capacity of an EGR cooler 4 is not high, air charging efficiency is heightened by cooling with water spray and the exhaust gas cooling action of the EGR cooler 4. The high cooling capacity of the EGR cooler 4 is therefore dispensed with so as to suppress the generation of condensed water and thereby preventing condensed water from being sucked into a combustion chamber.

The thermoplastic resin constituting the inner layer of weft yarn pref. has an m.p. of 150 deg.C or higher. When said m.p. is less than 150 deg.C, no pref. result is obtained because the deterioration of the thermoplastic resin is generated when the polyolefin resin is laminated to base cloth by extrusion coating. The polyolefin resin is laminated to at least one surface of the obtained base cloth by extrusion coating.
