摘要:
An electrically pumped light emitting device emits a light when powered by a power source. The light emitting device includes a first electrode, a second electrode including an outer surface, and at least one active organic semiconductor disposed between the first and second electrodes. The device also includes a dye adjacent the outer surface of the second electrode such that the second electrode is disposed between the dye and the active organic semiconductor. A voltage applied by the power source across the first and second electrodes causes energy to couple from decaying dipoles into surface plasmon polariton modes, which then evanescently couple to the dye to cause the light to be emitted.

The concentrated cooling apparatus includes a nozzle rotationally supported by a cold air guide path, the nozzle intensively jetting cold air to a high-temperature load region when a high-temperature load is placed inside a chilling chamber of the refrigerator. An infrared sensor is installed at the front of the nozzle, and the infrared sensor senses the high-temperature load region while being rotated together with the nozzle. A moisture removing device is formed at a side of the nozzle, the moisture removing device jetting cold air on the surface of the infrared sensor to remove moisture condensed on the surface of the infrared sensor.

Disclosed is a muffler in which a helicoil member is installed in each conduit, through which refrigerant gas flows from or into an expansion chamber during reciprocating movements of a piston in a cylinder. The helicoil member has diverse twisted angles and diverse twisted shapes, and serves to divide pulsation of noise, generated during the reciprocating movements of the piston, into pulsation of different phases, and then to merge the divided pulsation together, while allowing the refrigerant gas to have the form of a vortex flow. As pulsation of noise generated during an operation of sucking refrigerant gas pass along different travel paths defined by the helicoil member, a mutual interference occurs between the pulsation respectively emerging from the travel paths of the helicoil member. Therefore, an increased offset effect for the pulsation of noise is obtained, which maximizes a noise attenuation effect. It is also possible to prevent refrigerant gas from flowing reversal due to a counter pressure gradient occurring during the reciprocating movements of the piston. Accordingly, enhanced compressor efficiency is obtained.

The grooves formed of the plurality of cavities can damp vibration and noise having wide bands of frequency and amplitude generated from collision between the valve plate and the suction and discharging valves.

A concentration cooling apparatus for a refrigerator includes a housing which is mounted in a cold air guiding path, and a nozzle which is rotatably supported in the housing, for concentratedly injecting cold air to a region where a high temperature load is generated when the high temperature load is generated in a predetermined region inside a cooling chamber. An infrared sensor is mounted at the front of the nozzle, for sensing the region where the high temperature load is generated. The sensor rotates together with the nozzle and a frost drying sensor is installed on the upper surface of the nozzle, for drying frost on the surface of the infrared sensor. Thus, the reliability of the infrared sensor can be improved by preventing the formation of frost on the surface of the lens of the infrared sensor which detects whether the high temperature load is generated.
摘要:
A suction muffler in a reciprocating compressor is installed over a suction valve to attenuate complex sound pressure (noise) such as vibrational noise, valve sonance, flowing noise and pulsative noise produced from the suction valve when low temperature, low pressure refrigerant gas ejected from an evaporator is sucked into a cylinder via the suction valve and a suction portion of the cylinder. A Tesla valve having two distribution paths is mounted in the suction muffler to attenuate the complex sound pressure (noise) while preventing the reflow of the refrigerant gas into the suction muffler from the suction valve. As a result, the Tesla valve also enhances the cooling ability of the compressor and the attenuation effect.

The invention relates to a crank shaft having a guide groove allowing the movement of a crank pin so as to adjust the reciprocating distance of a piston according to the rotating direction. The crank shaft comprises a rotation shaft for inducing the rotating movement; and a crank arm connected to the rotation shaft at the center and having at one side a guide groove provided horizontal in the radial direction for allowing free movement of a crank pin and elastic means provided within the guide groove to enhance the performance of sucking and compressing fluid.Accordingly, smooth and soft compression is enabled to prevent the overpressure loss. Also, the sucking performance is improved by using additional retreat due to the elastic means.
