摘要： PURPOSE:To obtain a bioamorphous electrode excellent in its corrosion resistance further able to be cheaply manufactured by forming the electrode by an amorphous group alloy consisting of Cr, P, Ni. CONSTITUTION:A bioamorphous electrode, containing 5-40atom.% Cr and 15-35atom.% P, consists of the rest of Ni, being formed by a high corrosion resisting amorphous nickel group alloy of pitting, void and total surface corrosion proof resisting against a severe corrosion environment. The amorphous nickel group alloy is easily manufactured, having high corrosion resistance not corroding at all even in a severe corrosion environment like a solution of 46% hydrofluoric acid. When an electrocardiogram is taken by utilizing the amorphous electrode 1, it is brought into contact with a surface of the human skin 2, and an adhesive sheet 3 is adhesively attached from above the amorphous electrode 1. When the amorphous electrode 1 is clamped in its one end part by an alligator clip, a fine electric current, induced in the skin surface, reaches an electrocardiograph 5 via the amorphous electrode 1 and a lead cord 4a of the alligator clip 4, and the electrocardiogram is obtained.

摘要： PURPOSE:To block a neighboring fracture and to make it possible to nearly and surely control overflow within a short period of time at a low cost by scattering and throwing shape memory alloyed materials storing a net-like shape in an underground excavated hole. CONSTITUTION:Shape memory alloyed materials 4 storing a net-like shape and the like are provided. In the case overflow occurs during the excavation work, the shape memory alloyed materials 4 are scattered and thrown in an underground excavated hole and are entered in an overflow-causing fracture 3. After that, when sediment in the fracture 3 receives heat from a high temperature layer to raise temperature, the shape memory alloyed materials 4 are returned to the original net-like shape and the like, and an opening linked to the excavated hole of the fracture 3 is blocked. In addition, when temperature rising of the sediment in the fracture 3 can not be expected, hot water having a required temperature can be supplied.

摘要： PURPOSE:To prevent a transport pipe from the deposition and adhesion of scale therein and a reducing well from the capacity degradation caused by the separated scale flowing therein by pumping water into a transport pipe for two-phase flow of air and liquid extending from a pit port of a geothermal production well to a separator in pumping water into the geothermal fluid. CONSTITUTION:The SiO2 concentration in hot water is adapted to have the conditions from supersaturated one to unsaturated one by pumping water in geothermal fluid gushed out of a production well 1 under the two-phase air liquid fluid condition to prevent a transport pipe from the deposition and adhesion of scale. When water is pumped in the air-liquid two-phase current 3, only the latent heat of steam is deprived and a hot water amount is somewhat increased by condensing the steam, while the temperature of the hot water is not lowered and the concentration of silica or the like is diluted so that the transport pipe can be effectively prevented from the deposition of the scale. Also, a portion of hot water mist and dust contained in the steam can be taken into the hot water side to effectively clean the steam by water pumping.

摘要： PROBLEM TO BE SOLVED: To estimate the state of the underground crack between a well and an existing production well obtaining inflow time until muddy water deviates from the inside of the well being dug and reaches the production well, the distance between wells between inflow points, the viscosity coefficient of fluid, the column pressure of the muddy water, a production well inflow point pressure, and a storage layer effective layer thickness, and calculating a penetration rate and a penetration rate layer thickness product according to a specific expression. SOLUTION: Inflow time (t) until muddy water deviates from the inside of a well 1 being dug and reaches production wells 2 and 3, well distance (r) between the inflow points between the deviation point of the well being dug and the existing production wells 2 and 3, a viscosity coefficient (μ) of fluid near an interference inflow point, a muddy water column pressure Pi at the deviation depth of the well 1 being dug, a production well inflow point pressure Pp, and a storage layer effective layer thickness (h) are obtained, a penetration rate K=-V μr/(Pp-Pi)=-r/t×μr/(Pp-Pi) (V: flow rate) is calculated, further a penetration rate layer thickness product = k×h is calculated, and the state of the underground crack between the well 1 and the production wells 2 and 3 is estimated.
