Abstract: A refrigerator for drinks is provided. The refrigerator may have an open hole that is open upward, so a drink container may be inserted in an erect state in a cabinet through the open hole. An insertion guide connected to the open hole may be disposed in the cabinet and the width of the insertion guide may change in a height direction. Accordingly, a drink container may be guided by the insertion guide when being inserted into or taken out of the refrigerator for drinks.

Abstract: A refrigerator for drinks is provided. The refrigerator may include a cabinet having a storage compartment therein, and a dispenser nozzle disposed to be at least partially exposed outside the cabinet. A pump connection line being able to increase pressure in a drink container by delivering high-pressure air into the drink container and a tank connection line preventing oxidation of the drink in the drink container by delivering an unreactive gas into the drink container may be disposed in the cabinet. Accordingly, two functions of discharging a drink and preventing oxidation may be individually performed, so consumption of an unreactive gas may be reduced.

Abstract: A method for preventing an engine air flow calculation error applied to an engine system may classify an engine operation area of an engine into a sensor measurement deviation generation area, medium/high load areas, and a low load area by an ECU, and classify an air flow calculation applied to a cylinder charging amount of the engine as one of an air flow calculation control applying a compensation measurement air flow to the sensor measurement deviation generation area, an air flow calculation control applying a measurement pressure to the medium/high load areas, and an air flow calculation control applying a measurement air flow to the low load area, excluding influence of an HFM sensor error causing a change in a fresh air charge and inaccuracy of an exhaust gas recirculation (EGR) air flow modeling/active purge air flow modeling in the entire operation area of the engine.

Abstract: A method for controlling the air-fuel ratio of a vehicle includes: calculating the air amount charged in a cylinder of an engine by using a fresh air amount, a residual air amount remaining inside the cylinder of the engine, and a backflow gas amount flowing back into the cylinder upon the valve overlap of an intake vale and an exhaust valve of the engine, correcting it with the purge gas flow rate supplied to an intake manifold of the engine when the active purge system is operated, calculating the final fuel amount by correcting the fuel amount injected by a fuel injection device with the amount of the fuel component contained in the purge gas when the active purge system is operated, and controlling the air-fuel ratio based on the final air amount and the final fuel amount.

Abstract: A welding automation system that uses the shape of a welding region includes a welding torch that is installed in a robot and welds a parent metal fixed on a mounting part. A line laser emits a laser beam to a welding line region that is spaced apart from a welding point of the welding torch. A detector images and detects, from a predetermined angle, the shape of the laser beam. A control unit receives information from the detector and controls transportation of the robot and drives the welding torch along the welding region so that the welding torch corresponds with the welding region. The welding torch is installed on a slider that moves vertically and laterally relative to the robot. The control unit controls movement of the robot and/or the mounting part to correspond to transportation coordinates obtained by the calculation unit, and controls driving of the welding torch.
