Title: Zn-ni composite electroplated steel sheet excellent in property after coating
Inventor: SHINDO YOSHIO
IPC: C25D15/02
Filed: 1988-12-19
Abstract: PURPOSE:To obtain a Zn-Ni composite electroplated steel sheet excellent in properties after coating and adhesive strength of plating by incorporating specific amounts of Mg and cation polymer to a Zn-Ni alloy plating. CONSTITUTION:Mg and cation polymer are incorporated to a Zn-Ni alloy plating by 0.1-10wt.% and 0.001-5wt.%, respectively. As the above cation polymer, quaternary amine polymer is preferred. The above-mentioned combinedly added Mg modifies a phosphate film applied to the plated surface and improves properties after coating, and also, it makes Zn corrosion products dense and stabilizes them and inhibits the progress of corrosion under the coated film. Further, the cation polymer has a function of accelerating the eutectoid of Mg whose deposition potential differs greatly from those of Zn and Ni. By this method, the Zn-Ni composite electroplated steel sheet excellent in properties after coating and adhesive strength of plating can be obtained.

Title: Method for diagnosing deterioration of wire and cable
Inventor: AKIBA ISAO
IPC: G01N27/22
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To diagnose deterioration of insulation layer nondestructively, easily and accurately by detecting variation of dielectric loss of insulator in wire and cable in low frequency region. SOLUTION: Pulse voltages +Vstep and -Vstep are applied from pulse power supplies +V and -V to a cable sample Cs where two or more insulated cores coated with an insulator is sheathed with insulating resin and a reference capacitor Cref. Capacitance Cs (t) of the sample Cs is then determined based on an output voltage Vout generated from potential response to the applied voltage and the voltage Vstep. Permittivity ε (t) determined from the capacitance Cs (t) and the geometrical capacitance Cg of the sample Cs is then converted into a function of frequency thus determining the dielectric loss, i.e., tanδ, at an arbitrary frequency. As the deterioration of insulator progress, tanδ increases in low frequency region of 1Hz or below while exhibiting strong correlation with total tensile elongation.  Consequently, the deterioration of insulator in wire and cable can be diagnosed by determining tanδin low frequency region.

Title: Artificial dental root
Inventor: TAKESHITA MASAAKI
IPC: A61C8/00
Filed: 1987-12-19
Abstract: PURPOSE:To allow a collagen fiber bundle to grow naturally around a dental root in a vertical direction, by bringing the surface, which is brought into contact with bone tissue, of an artificial denstal root to a porous structure provided with pores having a pore size of 40mum or less. CONSTITUTION:A dental root 1 consists of a metal material such as Ti or a Ti alloy and ceramics such as alumina or zirconia. The porous surface 2, which is brought into contact with bone tissue, of the dental root 1 is brought to a porous structure having pores all or a part of which have a pore size of 40mum or less. By this constitution, this dental root after prosthesis becomes such a state that a collagen fiber bundle penetrates in the porous part having a pore size of 40mum or less. Therefore, the dental root becomes a state packed in a collagen layer and is brought into contact with bone tissue through said collagen layer and a tissue structure similar to an actual natural tooth is obtained. Therefore, the impact pressure at the time of occlusion is buffered by the collagen fiber group. As a result, the sinking of the dental root having this structure is not almost generated after prosthesis.
