Abstract: An optimal route derivation server configured to derive an optimal route of a ship includes a storage unit configured to store marine data including winds, wave heights, and currents by matching the marine data with sailing data at each time point and each location included in the sailing data of each sailing obtained from an Automatic Identification System installed on a ship, a corrected ship speed derivation unit configured to derive a first corrected ship speed by excluding an influence of currents from a speed of the ship for each sailing, a second corrected ship speed by considering an influence of winds on the first corrected ship speed at each location, and a third corrected ship speed by considering an influence of waves on the first corrected ship speed at each location, a speed down curve derivation unit configured to derive a first speed down curve related to winds and a second speed down curve related to waves based on a basic speed, the second corrected ship speed and the third corrected ship sp

Abstract: The present disclosure provides a method for providing route information for ship including coastal weather information, including: determining a standard route based on information about the origin and destination, determining at least one alternative route based on filtering information and the information about the origin and destination received from a user, and providing the user device with information about the standard route and the at least one alternative route such that the standard route and the at least one alternative route are output on a screen of the user device for comparison.

Abstract: A method for treating a surface of a magnesium-based metal is disclosed for realizing a metallic texture of the magnesium-based metal. The method includes a buffing step of chemically polishing a surface of a magnesium-based metal by using a chemical polishing agent containing sodium nitride and sodium citrate; an immersing step of immersing the magnesium-based metal, which has been subject to the buffing step, into a strongly alkaline electrolyte solution of pH 11 or above; and an anodizing treatment step of forming a transparent anodizing film on the surface of the magnesium-based metal by applying current with a current density of 0.01 to 1 A/dm2 to the magnesium-based metal in the strongly alkaline electrolyte solution.

Abstract: An object of the present invention is to provide a dryer and a method for controlling the same, in which a rotation speed of a drying drum is made to reach to a preset rotation speed regardless of a load of the drying object held in the drying drum. For this, the dryer includes a drying drum rotatably mounted in a body, a driving unit mounted to enable to vary a rotation speed of the drying drum, sensing means for sensing a load of the drying object in the drying drum, and a control unit for controlling the driving unit to vary a rotation speed of the driving unit proper to the load with reference to a sensing signal from the sensing means. For this, the method includes the steps of applying a drying course to start drying, sensing a load of a drying object with an electrode sensor after starting the drying course, and varying a rotation speed of the driving motor with the load sensed thus.

Abstract: A dryer and control method thereof are disclosed, by which energy saving and optimal temperature maintenance within a drying drum are enabled in a manner of diversifying a heater temperature by varying a rotational speed of a blowing fan used for the dryer. The present invention includes a drying drum for accommodating an object to be dried therein, a blowing fan provided to enable an air to pass through the drying drum, a heater heating an air supplied to the drying drum, a temperature sensor sensing a temperature within the drying drum, a driving motor generating a driving force to rotate the drying drum and the blowing fan, and a control unit controlling an RPM (revolutions per minute) of the driving motor to be varied according to a sensing result of the temperature sensor.

Abstract: A dryer is provided. The dryer includes a housing coupled to a rear wall of a drum, a housing cover, a bearing, and a supporting holder. The housing cover is coupled to the housing. The bearing is interposed between the housing and the housing cover. The supporting holder is interposed between the housing and the bearing.

Abstract: There is provided an air inlet structure of a laundry dryer. In the air inlet structure, a base defines an air inlet, a front cabinet is disposed in front of the base and defines a suction hole to pass ambient air into the base, a cooling fan is stably disposed in the base to suck the ambient air, a blower tube forms a flow passage for the ambient air, a blower cover is fixed to the base to connect the blower tube and the cooling fan, and an air guide is disposed between the base and the blower cover, the air guide having a shroud at a center portion.

Abstract: Disclosed is a drawer structure for storing condensed water generated during the drying procedure. The drawer prevents the condensed water form being leaked out of the dryer though the condensed water is fully filled in the drawer and overflowed from the drawer. Thus, a user may not throw away the condensed water whenever the laundry is dried.

Abstract: A dryer and a motor mounting structure of the same are provided. The dryer includes: a cabinet; a drum housed inside of the cabinet; a motor for providing a driving force to the drum; a belt for connecting a driving shaft of the motor with the drum; a base disposed at a lower side of the drum; a motor supporter having a pass-through part, which is disposed at its one side and supports the driving shaft; a cushion provided between the driving shaft and the motor supporter; a guide rib provided at the base; and a guide rib inserting part provided at the motor supporter to have a corresponding shape of the guide rib, such that the motor supporter is slid and mounted on the base.

Abstract: A laundry dryer includes a base, a condenser receiving unit formed in the base, and a condenser inserted in the condenser receiving unit and provided with an insertion member.

Abstract: A laundry dryer includes a dry drum in which laundry is loaded, a noise reduction member mounted on an outer circumference of the dry drum to absorb vibration/noise, a lift attached on an inner circumference of the dry drum to lift the laundry, a coupling member coupling the noise reduction member and/or the lift to the dry drum, and a belt disposed around the dry drum.
