Abstract: PURPOSE: A system for monitoring a fire by using a multiple optical fiber sensor is provided to utilize in a nuclear reactor or a gas pipe system having a problem that the electromagnetic interference is generated. CONSTITUTION: A system for monitoring a fire by using a multiple optical fiber sensor includes a control unit, an optical fiber system, an optical switch and a multiple optical fiber sensors. The multiple optical fiber sensor is provided with a light source, a plurality of optical fibers, a sensing unit, an optical detector and a signal processor. The sensing unit is capable of generating an interference between the external physical value and the light passing therethrough. The optical detector is made of a complex semiconductor. And, the signal processor is capable of measure the intensity of light, the change of phase in the interferometer and the change of wavelength in the light.

Abstract: PURPOSE: A polyurethane composition and a sponge for body exfoliation manufactured therefrom are provided to effectively perform both exfoliation and skin protection by utilizing the function of microcells of polyurethane foam and microparticles of loess simultaneously. CONSTITUTION: The polyurethane composition comprises: 100pts.wt of a hardening agent which comprises 35-95wt% of a mixed polyol where polyether polyol having a molecular weight of 300-2000 and polyester polyol are mixed in a weight ratio of 80-95:5-20, 1-60wt% of loess, 0.1-2wt% of a hardening accelerator, 0.5-5wt% of an amine catalyst, 0.1-5wt% of a pigment, 0.5-15wt% of a foaming agent and 0.5-5wt% of a silicone surfactant; and 100-130pts.wt of polyisocyanate. The sponge for body exfoliation is manufactured by foaming the polyurethane composition to give a block foam, aging the block foam at room temperature for 2-3 days and cutting it into a desired shape.
