Abstract: According to an exemplary embodiment of the present disclosure, disclosed is an aluminum coated blank that includes a first coated steel sheet; a second coated steel sheet connected to the first coated steel sheet; and a joint portion that connects the first coated steel sheet to the second coated steel plate at a boundary between the first coated steel sheet and the second coated steel sheet.

Abstract: A system for managing a seat occupancy status by a passenger and a control method of the system includes a seat belt sensor provided for each seat to detect a fastening or unfastening of the seat belt, a pressure detection unit provided for each seat to detect occupancy or non-occupancy of a seat by a passenger and pressure of the seated passenger, a secondary control unit provided for each seat and woken up by radio communication with a vehicle to alert to an unfastened state of the seat belt when the seat belt is unfastened upon determining, by a seat belt sensor, whether the seat belt is fastened, and a primary control unit provided in the vehicle to perform radio communications with each secondary control unit and check an abnormality based on reception or non-reception of the system data transmitted from the secondary control unit.

Abstract: According to an exemplary embodiment of the present disclosure, disclosed is an aluminum coated blank that includes a first coated steel sheet; a second coated steel sheet connected to the first coated steel sheet; and a joint portion that connects the first coated steel sheet to the second coated steel plate at a boundary between the first coated steel sheet and the second coated steel sheet.

Abstract: Disclosed are an aluminum-coated blank, a manufacturing method thereof, and an apparatus for manufacturing the same. The blank includes two or more aluminum-coated steel sheets connected together by a joint, each of the steel sheets including: a base steel sheet including 0.01-0.5 wt % of carbon, 0.01-1.0 wt % of silicon, 0.5-3.0 wt % of manganese, greater than 0 but not greater than 0.05 wt % of phosphorus, greater than 0 but not greater than 0.01 wt % of sulfur, greater than 0 but not greater than 0.1 wt % of aluminum, greater than 0 but not greater than 0.001 wt % of nitrogen, and the balance of iron and other inevitable impurities; and a coating layer including aluminum and formed on at least one surface of the base steel sheet.

Abstract: A water cooling type air conditioner is provided. The water cooling type air conditioner includes first and second heat exchangers, a refrigerant pipe, and a direction controlling unit. The first heat exchanger performs heat exchange between air and refrigerant. The second heat exchanger performs heat exchange between the refrigerant and cooling water. The refrigerant pipe is connected between the first heat exchanger and the second heat exchanger to guide a flow of the refrigerant. The direction controlling unit is disposed on one side of the second heat exchanger and controls the refrigerant and the cooling water flowing inside the second heat exchanger to flow in respectively opposite directions.

Abstract: A water-cooled air conditioner includes a first heat exchanger where indoor air is heat-exchanged with refrigerant, a compressor for compressing the refrigerant, an accumulator that is installed adjacent to the compressor to filter off liquid-phase refrigerant so that only gas-phase refrigerant can be introduced into the compressor, a plate-shaped second heat exchanger where the refrigerant compressed by the compressor is heat-exchanged with the water, and a refrigerant bypassing unit that selectively operates to allow a portion of the refrigerant compressed in the compressor to be directly returned to the second heat exchanger.
