摘要:
A variable capacity rotary compressor to prevent an eccentric bush and a locking pin from being deformed or worn out due to a variance in a pressure of a compression chamber as a rotating shaft rotates. The compressor includes upper and lower compression chambers having different interior capacities thereof, and a rotating shaft. Upper and lower eccentric cams are provided on the rotating shaft to be eccentric from the rotating shaft in a common direction. Upper and lower eccentric bushes are fitted over the upper and lower eccentric cams, respectively, with a slot provided at a position between the upper and lower eccentric bushes. The locking pin operates to change a position of the upper or lower eccentric bush to a maximum eccentric position. Further, surfaces of parts around first and second ends of the slot are heat-treated, thus increasing a hardness thereof.

A variable capacity rotary compressor including upper and lower compression chambers having different interior capacities, and a rotating shaft. Upper and lower eccentric cams are provided on the rotating shaft to be eccentric from the rotating shaft in a same direction. Upper and lower eccentric bushes are fitted over the upper and lower eccentric cams, respectively, in such a way that a maximum eccentric part of the upper eccentric bush is opposite to that of the lower eccentric bush, with a slot provided between the upper and lower eccentric bushes. A locking pin functions to change a position of the upper or lower eccentric bush to a maximum eccentric position. Further, upper and lower brake units are respectively provided between the upper eccentric cam and the upper eccentric bush, and between the lower eccentric cam and the lower eccentric bush.

An air conditioner has a variable capacity rotary compressor, which allows the compressor to be smoothly re-started, thus increasing start reliability of the compressor. The air conditioner includes a compressor rotated in opposite directions. A drive unit rotates the compressor in a forward or reverse direction. A start determining unit determines whether the compressor has started to rotate in a forward direction or not. A control unit operates the drive unit so as to rotate the compressor in a direction opposite to the forward direction, and then re- start the compressor in the forward direction, when the compressor has failed to start. The air conditioner and a method of controlling the air conditioner allow the compressor to be smoothly and rapidly re-started even when the compressor has failed to re-start, thus increasing start reliability, and shortening a time required to re-start the compressor.

A textile, such as a hairpiece, includes a plurality of fiber single-ply threads. The plurality of fiber single-ply threads are grouped such that designs may be created on desired portions of the plurality of fiber single-ply threads, such as a decolorized portion. The textile includes a fixed part to hold the fiber single-ply threads. A variety of techniques may be used to create a design on the plurality of fiber single-ply threads with precision. For example, various dispersion dyes on transcription paper could be applied to a surface of the single-ply threads with a heat pressing process. The textile, exhibiting designs on a plurality of fiber single-ply threads, is also configured to be attached or adorned.

Provided is a reactive dye composition, comprising (i) a reactive red dye represented by Formula 1; (ii) one or more reactive dyes selected from the group consisting of a reactive yellow dye represented by Formula 2, a reactive orange dye represented by Formula 3 and a mixture thereof; and (iii) one or more reactive dyes selected from the group consisting of a reactive blue dye represented by Formula 4, a reactive blue dye represented by Formula 5 and a mixture thereof; and a method of dyeing a fiber material containing nitrogen or hydroxyl group using the same. Therefore, it is possible to provide fiber products having superior light fastness and combined colors.

A new method of designing and generating compounds having an increased probability of being drugs, drug candidates, or biologically active compounds, in particular having a therapeutic utility, is disclosed. The method consists of identifying a group of bioactive compounds, preferably of diverse therapeutic uses or biological activities and built on a common building block. In this group of compounds, side chains modifying the building block are identified and used to generate a second set of compounds according to the proposed methods of hybridization”, “single substitution” or “incorporation of frequently used side chains”. If the compounds in the second set built on the same building block contain an unusually large number of drugs, preferably with diverse therapeutic uses or biological activities, they constitute a “hot spot”. A focused combinatorial library of the “hot spot” is then generated, preferably by methods of combinatorial chemistry, and compounds of this library are screened for a variety of therapeutic uses or biological activities. The method generates drugs, drug candidates, or biologically active compounds with a high probability, without requiring any prior knowledge of biological targets.

A microwave oven is disclosed having a cooking chamber, at least one heat outlet provided in a sidewall of the cooking chamber, at least one heat inlet provided in the center of the sidewall of the cooking chamber, and a convection assembly. The convection assembly is disposed on an external side of the sidewall of the cooking chamber, and includes a fan, a heating element, and at least one guide bracket which guides heat from the heating element through the at least one heat outlet and into the cooking chamber. According to this configuration, a microwave oven heats food more evenly and efficiently.

A variable capacity rotary compressor including upper and lower compression chambers in which compressing operations are carried out. A slot is provided at a predetermined position between upper and lower eccentric bushes. A locking pin makes either of the upper and lower eccentric bushes be disposed at a maximum eccentric position. Since the locking pin has a diameter which is larger than a locking hole in a shaft by about 0.02 mm to 0.06 mm, the locking pin is fitted into the locking hole in a press-fit method. Further, the locking hole has a threaded part and a non-threaded part, and the locking pin has a threaded part to correspond to the threaded part of the locking hole and a non-threaded part to correspond to the non-threaded part of the locking hole.

A two-dimensional wavelength/time optical CDMA system employing balanced-modified pseudo random noise (PN) matrix codes is provided. Through an inverse-exclusive OR operation of a pair of modified PN code, the balanced codes are generated as optical CDMA codes in the form of a new matrix. When the codes are applied to an optical CDMA system to perform encoding and decoding, if the same number of channels as the number (M−1) of subgroups of the codes are connected, the system becomes an MAI-free system, and even if the number of channels connected is twice the number of the subgroups, an error-free system can be established. Accordingly, the number of channels that can be used simultaneously is doubled compared to the prior art method such that the economical efficiency of the optical CDMA system improves.
