摘要:
Disclosed is a printed circuit board (PCB) and a method of fabricating the same. A contact portion is formed on an internal layer of the multi-layered PCB. A groove is formed so as to expose the contact portion of the internal layer. A chip package is mounted on the PCB while being flip-chip bonded to the exposed contact portion of the internal layer.

An ice-making unit, which uses a cooling unit in which a refrigerant pipe is received, and a refrigerator having the same. The cooling unit includes a cooler for conduction of coldness, an inner surface of the cooler coming into direct contact with the refrigerant pipe, realizing a direct cooling type ice making operation. A rotatable tray is provided under the cooling unit, so that an ice-separating member attached to the cooling unit pushes ice upon rotation of the tray, allowing the ice to be discharged in a direction opposite to the rotating direction of the tray.

A refrigerator and an ice-making system thereof, which may maximize space utilization inside a storage compartment. To this end, an ice-making device is horizontally wide and vertically thin, and an ice discharge port of a dispenser unit is oriented obliquely or parallel to a surface of a storage compartment door to reduce the thickness of the dispenser unit. An icemaker and an ice storage container to receive ice made by the icemaker are horizontally arranged parallel to each other within the ice-making device. A transfer channel is formed in an inner foamed portion of the storage compartment door to maximize space utilization inside the storage compartment and door shelves.

A control method of a refrigerator to prevent frost from being formed in an ice making chamber. The refrigerator includes an ice making chamber refrigerant pipe to supply a refrigerant to make ice in a direct cooling manner and an ice making chamber circulation fan to create a forced air stream to circulate air in the ice making chamber. The control method includes determining whether temperature of the ice making chamber is lower than a predetermined temperature and driving the ice making chamber circulation fan in a state in which the temperature of the ice making chamber is lower than the predetermined temperature and the refrigerant flows in the ice making chamber refrigerant pipe or when flow of the refrigerant in the ice making chamber refrigerant pipe is interrupted in a state in which the temperature of the ice making chamber is lower than the predetermined temperature.

An Organic Electro Luminescence Display (OELD) to perform a sheet unit test includes a pixel unit including: a plurality of pixels to receive a first power supply voltage (ELVDD), a second power supply voltage (ELVSS) and scanning signals to emit light; a scan driving unit to supply the scanning signals to the pixel unit; and a test unit to test whether or not a defect in the pixel unit is present, and further includes a first wire group arranged in a first direction and having a floated end; and a second wire group arranged in a second direction and having a floated end. This allows the sheet unit test to be conducted without scribing each OELD, by supplying the power supply voltages and the signals for their tests into a plurality of the OELDs formed on a motherboard.

Provided is a micro-column electron beam apparatus including: a base; an electron lens bracket on which an electron lens modulate can be fixed, mounted in a central portion of the base; an electron beam source tip module vertically disposed on the electron lens module; a pan spring plate stage module that is mounted over the base, supports the electron beam source tip module at a central portion thereof, and includes a three-coupling pan spring plate portion including first through third spring units that are coupled to the electron beam source tip module in three directions on a plane perpendicular to the vertical axis, which vertically passes the center of the electron beam source tip module, to elastically support the electron beam source tip module in three directions; a first piezoelectric actuator coupled to the pan spring plate stage module to move the electron beam source tip module along a first axis perpendicular to the vertical axis; and a second piezoelectric actuator coupled to the pan spring plate stage module to move the electron beam source tip module along a second axis perpendicular to the vertical axis and the first axis.
摘要:
A refrigerator including a main body provided with a refrigerating chamber at an upper section and with a freezing chamber at a lower section, an ice making tray disposed in an upper space of an ice making chamber defined in the refrigerating chamber, a first storage container disposed in a lower space of the ice making chamber to store ice falling down from the ice making tray, and a second storage container disposed in a freezing chamber to store ice transferred from the ice making tray. The main body includes a guide channel to guide, when the first storage container reaches an ice-full state, ice falling from the ice making tray to the second storage container in the freezing chamber. The size of the ice making chamber is greatly reduced while a sufficient amount of the ice may be stored, thus securing a larger available space in the refrigerating chamber.
