Title: Semiconductor device
Inventor: IKO KAZUO
IPC: C08G59/00
Filed: 1985-02-19
Abstract: PURPOSE:To prevent the formation of cracks in a passivation layer by sealing a semiconductor element by using an epoxy resin composition containing epoxy resin, a phenolic novolak group curing agent and amorphous silica powder having specific sphericity. CONSTITUTION:A semiconductor element is sealed by using an epoxy resin composition containing epoxy resin, a phenolic novolak group curing agent, one molecule thereof has two or more of hydroxyl groups, and amorphous silica powder having the Wadel's sphericity, preferably, sphericity of 0.7-1.0. Epoxy resin having epoxy equivalent of 175-250 and the softening point of 60-130 deg.C can particularly be employed preferably as the epoxy resin. Novolak type epoxy resin is preferable as the form of the epoxy resin. The phenolic novolak group curing agent having the softening point of 60-120 deg.C can specially be used preferably as the curing agent. It means that a particle is close to a true sphere with an approach to 1.0 of the Wadel's sphericity. Sphericity of less than 0.5 results in the formation of a number of sharp projecting pieces, and is undesirable.

Title: Blood coagulation accelerator
Inventor: ANRAKU HIDEO
IPC: G01N33/48
Filed: 1984-02-21
Abstract: PURPOSE:To reduce the blood coagulation time by arranging a non-enzyme activator as XIIth blood coagulation factor, a protease for hydroanalyzing the bond of Arg or Lys residual group with an amino residual group and a coagulating agent. CONSTITUTION:The XIIth blood coagulation factor employs a compound of the formula I (wherein A represents a residual group of a cyclic compound), for example, elaiden oxide II as given by the formula II and 1,2,3-triketohydrindene as given by the formula III as non-enzyme activator. For example, trypsin, thrombin and snake-poison thrombin enzyme are used as protease to hydroanalyze the bond of Arg or Lys residual group with any amino residual group. As this blood coagulation promotor contains the compound of the formula I and the protease, the XII factor can be activated quickly to reduce the blood coagulation time and thus, it is used effectively for clinical examination and stanching because of excellence in the separability between serum and clot.
