Abstract:
The present invention relates to a radiant heating-and-cooling system for an individual house. More specifically, the purpose of the present invention is to provide the radiant heating-and-cooling system for an individual house which can utilize radiant heating equipment mostly utilized in the winter and as an air-conditioning equipment in the summer, and has no need to install a separate cooling device to cool cooling water using tap water supplied through a water utility when cooling in the summer as a cooling source of a heat exchanger for cooling. According to the present invention, the radiant heating-and-cooling system for an individual house includes: a distributor distributing heating water or cooling water through a cooling-and-heating pipe (P) installed on at least on among an indoor floor, a wall, or a ceiling; a heating boiler heating the heating water; the heat exchanger for cooling which cools the cooling water using tap water supplied through a water utility as the cooling source; a cooling-and-heating water supply line supplying the heating water or cooling water to the distributor; a cooling and heating water return line returning the cooling water or heating water from the distributor; a water tank temporarily storing the tap water discharged from the heat exchanger; a tap water distributing line supplying the tap water penetrated through the heat exchanger as water for everyday usage; and a control unit controlling the distributor according to indoor temperature.

PURPOSE: A transmission sheet including an optical fiber cable and a method and apparatus for detecting a polishing end point in a CMP(Chemical Mechanical Polishing) process are provided to prevent the detection deterioration of the polishing end point due to an air gap, a slurry leakage, and steam by integrating the optical fiber cable with the transmission sheet. CONSTITUTION: A platen(30) rotates around a rotary shaft. A polishing pad(20) and a transmission sheet(23a) are located on the upper side of the platen. A polishing head(40) rotates by a rotary shaft(80) fixed to an arm(60). An optical fiber cable(25) is formed in the transmission sheet. An optical detector(50) is combined with the lower side or lateral side of the platen.

PURPOSE: A repairing agent for reinforcing concrete is provided to ensure high strength after construction and to protect the inside and the outside of the concrete while recovering the performance of concrete with water resistance. CONSTITUTION: A repairing agent for reinforcing concrete comprises an A agent including polymeric MDI, polyol, and butylacetate and a B agent including polyoxypropylene diamine, diethyltoluene diamine, polyether polyol, and epoxysilane. The A agent is manufactured by the steps of: putting polymeric MDI in a reactor and raising the temperature of the reactor to 40°C; putting polyol in a reactor and raising the temperature of the reactor to 80 °C; performing a reaction at 80 °C for 2 hours; cooling the resultant to room temperature and adding butylacetate; and uniformly mixing the mixture for 15~25 minutes.

PURPOSE: A device and method for manufacturing a tail trim of a vehicle and the tail trim manufactured by the same are provided to perform a forming step and a curling step at the same time and to reduce the number of the steps. CONSTITUTION: A device for manufacturing a tail trim of a vehicle comprises a forming part(211) and a press liquid pressure forming part(221). The forming part is a molding frame(212) molding tail trim members. The molding frame is formed at inner both side of the forming part. A protrusion is formed on the molding frame. The press liquid pressure forming part comprises a presser part(222) and a hydraulic transmission part(223). The presser part pressurizes the tail trim member in one side or the either side. The hydraulic transmission part is formed in the end of the presser part. The hydraulic transmission part injects the liquid component to the tail trim member inside.
