The purpose of the present invention is to provide a method for manufacturing a light-amplified optoelectronic device, on which pristine or doped graphene is transferred. Specifically, the method includes the steps of: depositing a first electrode, as a thin film, on the light emitting device; transferring pristine or doped graphene on the electrode thin film; etching the light emitting device in contact with the electrode thin film on which the transferred graphene has been transferred, thereby removing a part of the electrode thereon; spin-coating photoresist on the etched light emitting device; removing the photoresist from the spin-coated light emitting device, thereby forming an electrode thin film in a spin form and the pristine transferred to or graphene doped to the electrode thin film; and depositing metal on a second electrode.

Light emitting device light-amplified with graphene and method for manufacturing same

The present invention relates to a washing machine. A washing machine according to an embodiment of the present invention comprises: a casing for forming the exterior; a tub arranged inside the casing; a drum rotatably provided in the tub to contain laundry; and a water supply/distribution device arranged inside the casing, the water supply/distribution device having a temporary space, in which water flowing in from the outside gathers, a plurality of discharge ports for distributing the water in the temporary space towards a plurality of locations, and a pressure limiting unit for limiting the rise of water pressure in the temporary space.

Washing machine with water supply distributor

A system including an enclosure of a washing machine, a drum within the enclosure, a mixing unit, within the enclosure but separate from the drum and in fluid communication with the drum, a water supply unit coupled to the mixing unit, a reservoir having a conduit fluidly coupled to the mixing unit, and a container connecting assembly configured to fix a spout of a container to the reservoir. An apparatus including a reservoir, external to a washing machine, to receive a liquid wash aid, a container connecting assembly coupled to the reservoir and configured to fix a spout of a container containing liquid wash aid to the reservoir, a flexible conduit to pass liquid wash aid from the reservoir to the washing machine, and a wash aid control unit connected to the flexible conduit and adapted to meter a flow of liquid wash aid from the reservoir to the washing machine.

Washing machine system and washing method

Disclosed are a washing machine and a control method thereof. The control method of the washing machine, including two or more balancing units which are independently movable, includes sensing the weight of laundry to be washed while identically maintaining a phase difference between the two or more balancing units and rotating a drum, and reducing eccentricity of the drum while moving at least one of the two or more balancing units simultaneously with rotation of the drum.

Washing machine and control method thereof

Provided is a photodetector including a graphene p-n homogeneous vertical-junction diode by evaluating photodetection characteristics of the manufactured graphene p-n vertical junction according to the amount of doping. The photodetector comprises a substrate and graphene having a p-n homogeneous vertical junction as a photodetection layer formed on the substrate, wherein the photodetection layer has a detectability of 10E11 (Jones) or higher within the range of 350 nm to 1100 nm, and first and second electrodes are formed on the photodetection layer.

Photodetector

A bypass device of a refrigerator connected to an inrush current preventing device bypasses an input power when the input power is applied to the refrigerator, and a controller controls the input power input through the inrush current preventing device in response to a voltage measured by a voltage measuring device, recovers a function of the inrush current preventing device, and drives a compressor. Therefore, a standby time to re-drive the refrigerator is decreased and convenience is enhanced.

Refrigerator and operating method thereof

There are provided a refrigerator and a method of controlling the same. The method of controlling a refrigerator includes varying stroke of an inverter linear compressor to operate the inverter linear compressor by a maximum output when a temperature of an inside of a freezer compartment or a refrigerator compartment is higher than a maximum output temperature and varying the stroke of the inverter linear compressor at one period interval to operate the inverter linear compressor when the temperature of the inside of the freezer compartment or the refrigerator compartment is no more than the maximum output temperature.

Refrigerator and the controlling method

A washing machine and associated washing method are provided. The washing machine may include a cabinet, a drum rotatably installed in the cabinet, and a spray nozzle provided inside the cabinet to spray washing fluid into the drum. A spraying direction of the spray nozzle may be varied based on a rotation direction of the drum to improve washing performance of the washing machine.

Washing machine and washing method

A refrigerator and a method of operating the same are disclosed. In the refrigerator and the method of operating the same, a voltage of an electric power input is measured and rectified through the half wave rectification or the full wave rectification in correspondence with the measured voltage, so that the refrigerator can be used without a voltage converting device when a voltage of the input power is changed. Therefore, the change or the modification of the circuit is not needed in order to use the refrigerator in other regions. Since components are compatible and utility of the components is improved, manufacturing costs can be reduced.
