A drum-type washing machine having a damper, and method, capable of effectively reducing vibration of a water tub includes a housing, a water tub in the housing, and a damper unit having one end affixed to an outer surface of the water tub and an other end affixed to the housing. The damper unit includes a cylinder having one end affixed to one of the housing and the water tub and a piston having one end affixed to the other one of the housing and the water tub and the other end in the cylinder elastically retractable to reduce the transmitted vibration. A frictional pad is on an inner surface of the cylinder or an outer surface of the piston to come into frictional contact, respectively, with the outer surface of the piston or the inner surface of the cylinder, thereby reducing the vibration of the water tub.

An exercise apparatus with both a mat rotating means operated by an electric motor and a foot support means to allow a user reclining on a mat to hang his/her body upside down from the foot support means or to do exercises, such as sit-ups, without help from another person. In the exercise apparatus of the present invention, the leg assembly includes movable and immovable legs, in which the movable leg is closed towards the immovable leg to close the leg assembly in an effort to increase space efficiency of the apparatus. The exercise apparatus also has a locking means for causing the leg assembly in a closed state to be maintained in a stable position, and a plurality of rollers mounted to an outside portion of either leg of the leg assembly to cause a user to easily move the heavy exercise apparatus when necessary.

The present invention relates to an LED lens, in which a planar bottom has a pair of halves symmetrically connected with each other about a reference line and narrowed in the vicinity of the reference line. A pair of substantially semicircular reflecting surfaces are extended from both edges of the bottom connected with both ends of the reference line. A radiating surface is connected with remaining edges of the bottom and semicircular edges of the reflecting surfaces. The reflecting surfaces reflect light beams are introduced from the LED chip through the bottom toward the radiating surface. The radiating surface radiates the light beams to the outside when the light beams are introduced to the radiating surface through reflection from the reflecting surfaces and directly through the bottom, so that the light beams are radiated to the outside in a predetermined beam angle.

A traffic measurement system and a traffic analysis method are provided. The traffic measurement system includes a plurality of measurement devices that collect all of packets flowing through Internet links, extract traffic data required to analyze traffic from the collected packets, and process the extracted data into predetermined flow types, and an analysis server that identifies applications of traffic by analyzing the traffic data transferred from the plurality of measurement devices as a whole, classifies the identified applications into predetermined traffic types, and outputs the classification result. The traffic measurement system measures the traffics in the Internet network and processes the measured traffics to generate detailed traffic statistical data according to applications. In particular, the traffics are analyzed considering measurement data from various points, and the data for identifying the applications are extracted from headers of the applications included in payloads of IP packets in real time. Accordingly, detailed traffic analysis result is provided.

The present invention provides a writing/reading control method of HD stream. The present invention buffers an HD stream in an HDD, transfers the buffered HD stream to a DVD module to record the stream in a DVD medium, and reads the record stream. The present invention includes the steps of receiving an HD digital broadcast signal to demodulate into an HD stream in a PVR module, buffering the demodulated HD stream in an HDD, transferring the buffered HD stream to a DVD module to record the transferred HD stream in a DVD medium, reading the HD stream recorded in the DVD medium, buffering the read HD stream in the HDD, and decoding to read the read HD stream buffered in the HDD.

Provided is a flow generation method for Internet traffic measurement. In the flow generation method, dependency between packet collecting time and flow generating time is removed using a virtual timer and a flow generation completion processing interval is controlled to skip by a unit time in response to a user's request. Also, a fragmented packet processing method is selectively used at need and a FIN timeout is applied selectively to a timeout mechanism used in flow generation completion. Thereby, this invention can improve accuracy and efficiency of Internet traffic measurement.

Disclosed is a method for forming an inductor of a semiconductor device. The method includes the steps of forming an inductor pattern in an insulation layer after forming the insulation layer on a lower layer pattern, forming a barrier metal layer on a surface of the insulation layer including the inductor pattern, forming a copper thin film on the barrier metal layer by a thickness enough to fill the inductor pattern with the copper thin film, planarizing the copper thin film through a planar process by using slurry providing a high polishing rate identical to or more than 10,000 Å/min, and removing the barrier metal layer from the insulation layer through the planar process using slurry capable of polishing a barrier metal. Since slurry providing the high polishing rate is used, copper is polished at a high polishing rate under a conventional polishing condition or a low polishing pressure condition.

The present invention relates to an activated sludge process and apparatus for effectively removing organic matters, nutrient salts, particulates, etc. dissolved in sewage/waste water by operating activated sludge process of a high biomass concentration combined with a down-flow solid-liquid separation process utilizing a float-concentrated sludge blanket layer. The present invention provides a process for biologically treating sewage/waste water using activated sludge, comprising the steps of (a) floating a sludge by having micro bubbles rise to form a float-concentrated sludge blanket layer and (b) down-flowing mixed liquor, including activated sludge and solids, into the sludge blanket layer, thereby resulting in a solid-liquid separation and an apparatus for operating the process.
摘要:
A multi-functional marinade for fish and meat products that adds flavor to the fish or meat product and improves the texture and color of the fish or meat product during cooking. The marinade does not require the addition of other ingredients and can be applied immediately before cooking. The marinade can be a solid powder that is coated on the food or a liquid that is brushed or sprayed on the food.
