    • 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.
    • 往复式压缩机的减振结构包括:壳体,具有用于引入制冷剂的吸入管和用于在其两侧排出制冷剂的排出管; 安装在壳体中以压缩制冷剂并由气缸,活塞,驱动单元和排出阀组件构成的组件; 安装在排出阀组件和排出管之间的环形管,其具有弯曲形状; 以及连接单元,用于连接回路管的第一点和面向第一点的回路管的第二点,从而减少振动传递。 因此,当活塞被操作时产生的振动可以通过包括环管和附加连接单元的许多路径传递到压缩机。 此外,由于其相位差,产生的振动可以彼此抵消,从而防止振动传递到整个壳体。 此外,可以防止由于振动引起的环管的连接部分的损坏,并且可以提高产品的可靠性。

    • An inkjet printing system for manufacturing displays includes a stage on which a substrate is mounted, an inkjet head for depositing ink on the substrate, and a transfer device for controllably moving the inkjet head to selected positions above the substrate. The inkjet head includes a frame having a plurality of openings and a plurality of single heads that are readily attachable to and detachable from respective ones of the openings. Since the inkjet head includes a plurality of attachable and detachable single heads, if one nozzle of the inkjet head is damaged or becomes dysfunctional, the system can be repaired by replacing only one of the single heads, without the need to replace the entire inkjet head. As a result, the maintenance costs of the inkjet printing system are reduced.
    • 用于制造显示器的喷墨打印系统包括其上安装有基板的台,用于在基板上沉积墨的喷墨头和用于将喷墨头可控地移动到基板上方选定位置的转印装置。 喷墨头包括具有多个开口的框架和可容易地附接到相应开口部分并可从其拆卸的多个单个头部。 由于喷墨头包括多个可附接和可拆卸的单个头,如果喷墨头的一个喷嘴损坏或变得功能失调,则可以通过仅替换单个头中的一个来修复该系统,而不需要更换整个喷墨头 。 结果,喷墨打印系统的维护成本降低。

    • A bone conduction speaker is utilized for hearing aid and other devices. The speaker's structure is improved by arranging a single permanent magnet above an iron piece coupled to a vibrating plate fixed to a resonator, containing at least one sound coil, enclosing a magnetic core located substantially beneath the center of plate. Audio signals are converted into oscillating current, input in the coil that alternates attractive/repulsing forces applied to the iron piece producing vibrations of the plate amplified by the resonator, further conducted through skin and skull to auditory nerves for sound recognition. The structure allows avoiding laborious adjustments of the permanent magnet means during the assembly process, freeing the internal space of resonator, enlarging the coil and core, improving performance, making the speaker compact and lightweight, reducing production costs. An embodiment is furnished with upwards standing parts disposed at two resonator's opposite ends, forming stable structure.
    • 骨传导扬声器被用于助听器和其他装置。 扬声器的结构通过在固定到谐振器的振动板上的铁片上方布置单个永久磁铁而被改进,所述振动板包含至少一个音圈,包围位于板中心的磁芯。 音频信号被转换为振荡电流,输入到线圈中,其交替施加到铁片的吸引力/排斥力产生由谐振器放大的板的振动,进一步通过皮肤和颅骨进行听觉神经以进行声音识别。 该结构允许在组装过程中避免对永磁体装置的费力调整,释放谐振器的内部空间,扩大线圈和磁芯,提高性能,使扬声器紧凑和重量轻,降低生产成本。 实施例具有设置在两个谐振器的相对端处的向上竖立部分,形成稳定的结构。

    • A delivery system employing nanoparticles of thiolated chitosan which complex with nucleic acids or other drugs. The system utilizes an approximately 33 kDa thiol-modified chitosan derivative resulting in highly effective gene delivery. Thiolation of chitosan resulted in reduced density of positive charges and DNA binding capacity. However, thiolated chitosan carrying a plasmid DNA expressing a green fluorescent protein (GFP) showed significantly higher GFP expression in various cell lines and in vivo in mice. Sustained delivery of plasmid DNA from thiolated chitosan was achieved by crosslinking thiolated chitosan/plasmid DNA nanocomplexes through inter- as well as intramolecular disulfide bonds under the physiological conditions. Thiolated chitosan nanoparticles have a great potential for gene therapy and tissue engineering.
    • 使用与核酸或其他药物复合的硫醇化壳聚糖的纳米颗粒的递送系统。 该系统利用约33kDa硫醇改性的壳聚糖衍生物,导致高度有效的基因递送。 壳聚糖的硫酸化导致正电荷的密度降低和DNA结合能力降低。 然而,携带表达绿色荧光蛋白(GFP)的质粒DNA的硫醇化壳聚糖在各种细胞系中和体内在小鼠中显示出显着更高的GFP表达。 通过在生理条件下通过交联和分子内二硫键交联硫醇化壳聚糖/质粒DNA纳米复合物,实现了硫醇化壳聚糖的质粒DNA的持续输送。 硫醇化壳聚糖纳米颗粒具有很大的基因治疗和组织工程的潜力。
