摘要:
A flash memory device having a spacer of a gate region formed in an oxide-nitride-oxide (ONO) structure and a source/drain region formed using the ONO structure. The outermost oxide in the ONO structure is removed and an interlayer insulating film is formed to ensure sufficient space between the gate regions. Thus, it is possible to prevent a void from being generated in the interlayer insulating film and prevent a word line from being electrically connected to a drain contact for forming a bit line.

An antenna apparatus for a portable terminal having a main board is provided. The antenna apparatus includes a main antenna that electrically connects to a feed line of the main board. A metal frame is constructed as part of a case frame forming an exterior of the portable terminal. The metal frame is divided into first and second parts that are separated. The first part electrically connects to the main antenna or to the main board feed line, and is designed to radiate. The second part electrically connects to a ground surface of the main board. The metal frame enhances overall antenna performance rather than causing degradation through interference.

An automatic ice maker for saving an ice making time. The automatic ice maker has a U-shaped resonator filled up with an inertia gas, a pair of ice trays attached to both ends of the U-shaped resonator in a reverse direction to each other, a pair of speakers attached to both ends of the U-shaped resonator for compressing and expanding parcels of the inertia gas by applying an acoustic pressure to the U-shaped resonator thereby varying a temperature distribution in the U-shaped resonator, a pair of heat exchangers for transferring an inner temperature of the U-shaped resonator to the ice trays, a reversible motor for driving the U-shaped resonator in a forward or a reverse direction at an angle of 180 degrees, and an electric control unit for sequentially operating the speakers and the reversible motor. The automatic ice maker can be adopted to a refrigerator or other refrigeration system. By the automatic ice maker, the ice making time can be saved and the productivity in making the ice increases.

Integrated circuit test systems include an input driver having an output terminal that is connected to a test system port and a biasing device that is connected between the test system port and a reference voltage. The biasing device comprises a Thévenin equivalent circuit that is represented by an impedance element and a nonzero power source. The impedance element may be used to match the impedance of a device under test, which can reduce distortion in signals passed between the device under test and the test system. Furthermore, the power source may be used to provide direct current (DC) signals at the pins of a device under test, which can allow the swing height (e.g., amplitude or magnitude) of the test signals to be reduced. That is, the test signals are superimposed upon the DC voltages to allow “high” and “low” logic levels to be manifested via relatively minor swings in the test signals. By reducing the swing height of the test signals, transmission speed can be improved thereby reducing round trip signal delay.

An apparatus for inspection of a reactor pressure vessel uses a laser driven type underwater wall climbing robot guided by a laser pointer. The inspection apparatus uses a small and light underwater wall climbing robot for the quick and adequate inspection of weld lines of a reactor pressure vessel. Position control methods are provided for the stable guidance of the robot to desired three dimensional inspection positions on the reactor pressure vessel.

An antenna device for improving antenna performance of a portable terminal having a metal edge installed on a case frame is disclosed. The antenna device includes a main board equipped with a power supply end for supplying power and a ground surface for grounding the main board, a loop radiator connected with the power supply end of the main board at first end and connected with the ground surface of the main board at a second end, and a metal body disposed along an edge of the portable terminal and electrically connected with the ground surface of the main board.

A refrigerator which can supply water from a household water supply system into an ice tray, or alternatively, can supply water from a separate water tank into the ice tray. The refrigerator has a housing having a refrigerating chamber, a freezing chamber, and an evaporator chamber which is disposed at a rear portion of the freezing chamber, an ice tray disposed in the freezing chamber, a motor assembly for rotating the ice tray when a liquid filled in the ice tray is frozen, a valve box installed on an upper surface of the housing for receiving the liquid from a household water supply system or from a liquid tank, a fluid path for guiding the liquid from the valve box to the ice tray, a rotating fan assembly for detecting an amount of the liquid flowed into the ice tray, a solenoid valve assembly for adjusting the amount of the liquid being supplied into the ice tray, and an electric control unit for operating the solenoid valve assembly based on an electric signal inputted from the rotating fan assembly.
