Abstract:
A method of homogeneously forming functionalized biocompatible oligomers includes the steps of dissolving a biocompatible oligomer in a solvent to form a solution, and admixing at least one π complex forming group to the solution, wherein the π complex forming group grafts to at least one location on the backbone of the oligomer to form a grafted oligomer. The oligomer is preferably oligochitosan and the solvent is preferably dimethylsulfoxide (DMSO). The degree of graft substitution can be at least 50%. The functionalized biocompatible oligomer can be used for drug detoxification through binding to a variety of target drugs.

Abstract:
A display device includes a substrate, first and second electrodes, and first, second, third and fourth organic patterns. The substrate includes a first region having first pixel regions, a second region having second pixel regions, and a third region having third pixel regions. The first electrodes are disposed at the first, second and third pixel regions. The first organic patterns are formed at the first pixel regions. The second organic patterns are formed at selected ones of the second pixel regions. The second organic patterns have substantially a same profile as that of the first organic patterns. The third organic patterns are formed at remaining ones of the second pixel regions. The fourth organic patterns are formed at the third pixel regions. The fourth organic patterns have substantially a same profile as that of the third organic patterns. The second electrode covers the first, second, third and fourth organic patterns. Therefore, an image display quality is enhanced.
Abstract:
A vibration reduction structure of a reciprocating compressor comprises: a case having a suction pipe for introducing a refrigerant and a discharge pipe for discharging a refrigerant at both sides thereof; an assembly installed in the case to compress a refrigerant and composed of a cylinder, a piston, a driving unit, and a discharge valve assembly; a loop pipe installed between the discharge valve assembly and the discharge pipe with a curved shape; and a connection unit for connecting a first point of the loop pipe and a second point of the loop pipe facing the first point and thereby reducing a vibration transmission. According to this, vibration generated as the piston is operated can be transmitted to the compressor through many paths including the loop pipe and the additional connection unit. Also, generated vibration can be canceled to each other due to its phase difference, thereby preventing vibration from being transmitted to the entire case. Also, a damage of the connection part of the loop pipe due to vibration can be prevented, and a reliability of the product can be enhanced.

Abstract:
In a method of manufacturing a light emitting element, a plurality of first electrodes arranged in a matrix shape is formed on a pixel area of a base substrate. A bank is formed between the first electrodes. A light emitting material is ejected on a portion of the first electrodes spaced apart from one another to form a plurality of first light emitting patterns. The light emitting material is erected on a portion of the first electrodes between the first light emitting patterns to form a plurality of second light emitting patterns. A second electrode is formed on the first and second light emitting patterns. Therefore, a luminance of the light emitting element is improved and uniformized.
Abstract:
A display apparatus includes a light-emitting unit. The light-emitting unit includes a first electrode, a bank, an organic light-emitting layer and a second electrode. The first electrode is formed on a substrate. The first electrode receives a first driving signal from a circuit unit. The bank surrounds sides of the first electrode and has a receiving portion formed on an upper face of the bank. The organic light-emitting layer is formed on the first electrode. The second electrode is formed on the organic light-emitting layer. The second electrode receives a second driving signal from the circuit unit. Therefore, even though the organic light-emitting material is abnormally dropped onto an unintended position, the receiving portion prevents the organic light-emitting material from flowing into a neighboring cavity, so that yield increases and productivity is enhanced.
Abstract:
In a valve assembly of a reciprocating compressor including a piston having a valve seat portion (26) at the front and plural suction (24) holes for sucking a fluid at regular intervals in the circumferential direction; and a suction valve (20) arranged on the valve seat portion (26) to perform opening/closing operation of the suction holes (24), wherein the suction valve (20) includes a fixed portion fixed to the valve seat portion (26) of the piston; an open/close portion formed at the outside of the fixed portion to perform opening/closing operation of the suction holes (24); and plural neck (32) portions formed between the fixed portion (28) and the open/close portion (30) at regular intervals. Accordingly, by minimizing fatigue occurrence according to continued opening/closing operation by reducing an opening angle of the valve, damage or breakage of the valve can be minimized.
