Title: Thermosetting resin composition, its prepolymer and its cured product
Inventor: TAKAHASHI AKIO
IPC: C08G59/40
Filed: 1982-04-30
Abstract: PURPOSE:A thermosetting resin composition which can be cured by heating into a cured product having excellent heat resistance and low water absorption, containing polyphenyl-methylene-polycyanamide and a polyepoxy compound. CONSTITUTION:A resin composition containing a polyphenyl-methylene-polycyanamide of the formula, wherein 0<n<=5.0, and a polyepoxy compound. When the compound of the formula and the polyepoxy compound are combined with a phenolic resin compound and/or a triallyl isocyanurate compound, an increase in the crosslinking density can be attained because in case of the phenolic resin compound, the hydroxyl groups react with the epoxy groups of the polyepoxy compound, while in case of the triallyl isocyanurate compound, the allyl groups radical-polymerize with the unsaturated bonds of the cyano groups in the compound of the formula. Thus, the glass transition point of a cured product can be improved.

An initial objective value determination means determines the aforementioned initial objective value to be a value smaller than the previously calculated blood pressure value on the basis of said blood pressure value. As a result, blood pressure can be efficiently measured.

Abstract: PURPOSE:To prevent any crack in semiconductor chip from occurring by a method wherein, when a copper wire is bonded on an electrode, an end of capillary chip or an end of copper wire is heated by inert gas at high temperature. CONSTITUTION:When a ball 8 is formed at the end of a copper wire 1 pierced through a capillary chip 7, a through hole 7a is fed with inert gas at high temperature from a feeding pipe 10 to heat the end of the capillary chip 7 and the ball 8 of copper wire 1 and after bonding the ball 8 on an electrode 3 of semiconductor chip 2 by thermal pressure fixing jointly using ultrasonic waves, the other end of copper wire 1 is stitch-bonded on a lead 4 by heating within the preferable temperature range of 100 deg.C-150 deg.C. Because the hardness of ball 8 can not be sufficiently lowered under 100 deg.C and the surface of copper wire 1 is remarkably oxidized at above 150 deg.C while the coefficient of friction between inner surface of capillary 7 and the copper wire 1 is also increased. Through these procedures, the bonding operation can be performed using a ball with lowered hardness, making the bonding conditions optimum without increasing the output of ultrasonic.
