Abstract: A refrigerator is provided in which, when a structure that secures space to place a container is provided in a dispenser, an object can be dispensed from the dispenser regardless of the position of the structure. The dispenser includes a dispensing port in which an object is dispensed, a switch installed in the dispensing port to dispense the object, a support pivotally installed in the dispensing port and unfoldable from a folded state to place various vessels thereon, and an access portion of the support providing access to the switch to activate the switch in the folded state of the support. The access portion may be a cut-off portion such that the switch is inserted into the support to be exposed or an auxiliary switch to transmit force to the switch when the object is dispensed to indirectly activate the switch. Moreover, the support may directly access the switch.

Abstract: A heat exchanger including upper and lower header tanks, a vertical baffle in the lower header tank defining first and second longitudinal chambers, a check valve, two tube rows, and a coolant inlet to the first chamber and outlet from the second chamber. The baffle includes a by-pass hole therethrough. One tube row includes a plurality of vertical tubes extending between the upper header tank and the first chamber of the lower header tank, and the other tube row includes a plurality of vertical tubes extending between the upper header tank and the second chamber of the lower header tank. The check valve creates a leak-proof seal during standard operating mode to prevent pressure release from the header tank and creates an air path between the header tank and the environment during draining mode to allow vacuum relief from the header tank.

Abstract: A method for assembling a cylinder assembly for a compressor including a cylinder block having a compression chamber defined therein, a cylinder head coupled to the cylinder block to seal the compression chamber, and a valve device interposed between the cylinder block and the cylinder head, the method including: supporting the cylinder block on an assembling jig, aligning the valve device and the cylinder head with the cylinder block by fastening guide pins through valve guide holes perforated through the valve device and head guide recesses formed at a surface of the cylinder head to be coupled to the valve device, fixing the cylinder assembly such that the cylinder block, valve device, and cylinder head do not separate, and removing the assembling jig from the cylinder assembly.

Abstract: A refrigerator with a chilled air leakage preventing device that has high insulating efficiency and an aesthetically pleasing appearance and that is not easily damaged is provided. The refrigerator with the chilled air leakage preventing device includes a cabinet for forming a storage compartment, a door for opening and closing the storage compartment, a gasket provided to the circumference of the door to seal a gap between the cabinet and the door, and a chilled air leakage preventing member for sealing the gap between the cabinet and the door when the door is closed.

Abstract: A refrigerator and a method of making shaved ice by controlling a period during which ice is fed into an ice-shaving compartment, thereby preventing ice from overflowing the ice-shaving compartment and preventing the ice-shaving compartment from being broken due to an excessive amount of ice. The method of making shaved ice comprises feeding cubed ice stored in an ice-storing unit mounted in a freezing compartment to a shaved ice-making unit mounted at a discharge port side of the ice-storing unit though an ice-feeding unit to make shaved ice, setting a driving time for the shaved ice-making unit, and setting a driving time for the ice-feeding unit. The driving time for the shaved ice-making unit is longer than the driving time for the ice-feeding unit.

Abstract: The present invention relates to a refrigerator having a shaved ice supplying device which includes an ice shaver for pulverizing ice cubes supplied from an ice storing box into shaved ice, and with a passageway structure for distributing the ice. The refrigerator comprises an ice supplying device to supply ice cubes, an ice shaver to pulverize the ice cubes, supplied from the ice supplying device, into shaved ice, and a dispenser adapted to allow the ice cubes supplied from the ice supplying device to be directly dispensed while allowing the shaved ice pulverized by the ice shaver to be dispensed.

Abstract: Disclosed are a waveguide type signal attenuator for attenuating an input signal as desired and a waveguide type signal terminator for making an input signal be utterly disappeared, where a manufacturing-easy resistor sheet is inserted into the center area, along which a traveling electromagnetic wave has the maximum intensity, of the signal attenuator and the signal terminator. In the signal terminator and the signal attenuator, a predetermined part of the waveguide which is formed in a lower conductive plate is expanded out along the half-height plane of the waveguide to form a resistor sheet setting groove and a portion of the elongated cavity positioned behind the resistor sheet setting groove forms a lower half of the waveguide. In addition, a resistor sheet is inserted between the resistor sheet setting groove and a protrusion part which protrudes from an upper conductive plate, of the half-height of the waveguide holds the resistor sheet to form an upper half portion of the waveguide.

Abstract: Provided is a non-radiative dielectric (NRD) waveguide modulator having a waveguide type hybrid coupler, in which by forming a waveguide type 180° hybrid coupler and waveguides as a single body, the structure is simplified and manufacturing processes are reduced such that consistency of characteristics is maintained, manufacturing time and cost are reduced, and consequently, manufacturability is improved.
