    • The present invention relates to an anisotropic conductive adhesive comprising an anisotropic conductive adhesive combined with a crystalline polymer to realize anisotropic conductivity and PTC (Positive Temperature Coefficient) characteristics at the same time. The anisotropic conductive adhesive having PTC characteristics according to the present invention comprises an insulating adhesive component and a plurality of conductive particles dispersed in adhesive component, in which the insulating adhesive component comprises a crystalline polymer. Since the anisotropic conductive adhesive according to the present invention includes a crystalline polymer, when temperature rises and the volume expands, electrical resistance is rapidly increased, whereby current flow is intercepted resulting in blocking current, providing PTC characteristics acting as a switch. Thus, it shows circuit protection function as well. Accordingly, it is possible to intercept a circuit upon occurrence of excess current without using a separate element for circuit protection such as PTC thermistor.
    • 本发明涉及包含与结晶聚合物组合的各向异性导电粘合剂以同时实现各向异性导电性和PTC(正温度系数)特性的各向异性导电粘合剂。 根据本发明的具有PTC特性的各向异性导电粘合剂包括分散在粘合剂组分中的绝缘粘合剂组分和多个导电颗粒,其中绝缘粘合剂组分包含结晶聚合物。 由于根据本发明的各向异性导电粘合剂包括结晶聚合物,当温度升高并且体积膨胀时,电阻迅速增加,由此截流电流导致阻塞电流,提供作为开关的PTC特性。 因此,它也显示电路保护功能。 因此,可以在不使用诸如PTC热敏电阻之类的用于电路保护的单独元件的情况下在发生过电流时截获电路。

    • An apparatus for producing an optical fiber preform to perform the deposition process by modified chemical vapor deposition. The Apparatus comprises a main heat source location sensor (800) for detecting the location of a main heat source for heating a substrate tube 100, an additional supporting device control part (1000) wiredly or wirelessly connected to the main heat source location sensor (800), and an additional supporting device (1100) wiredly or wirelessly connected to the additional supporting device control part (1000) for supporting the substrate tube (100). The present invention reduces the effective length of the substrate tube (100) by additionally supporting the substrate tube (100), thereby minimizing the deflection of the substrate tube (100). Particularly, it is possible to considerably reduce the deflection of the substrate tube at its initial part and thus to achieve a high deposition efficiency. Accordingly, it is possible to mass-produce an optical fiber preform of high quality.

    • A thermistor is disclosed, which comprises a resistance element having upper and lower surfaces and showing a resistance varying characteristics according to the change of temperature; first and second conductive layers formed on the upper surface of the resistance element and engaged to each other with a non-conductive gap interposed therebetween; first and second electrodes formed on the lower surface of the resistance element and electrically separated from each other; a first connector for electrically connecting the first conductive layer to the first electrode; and a second connector for electrically connecting the second conductive layer to the second electrode. Thus, the thermistor has a structurally point-symmetric shape, so it is possible to prevent the Tombstone phenomenon, caused by an asymmetric structure. Since the conductive layers having opposite polarities are engaged to each other with the non-conductive gap therebetween, the flow of current is increased and the resistance of the thermistor is decreased.
