    • An ink-jet image forming apparatus. The ink-jet image forming apparatus includes a print head having a plurality of nozzles to eject ink, an ink tank to store the ink, an ink supply passage to supply the ink in the ink tank to the print head, an ink return passage to return the ink in the print head to the ink tank, a regulator mounted in the ink supply passage to regulate ink flow supplied to the print head, a shut-off valve mounted in the ink supply passage, between the ink tank and the regulator, to intercept ink flow supplied to the regulator, and an ink pump mounted in the ink return passage to forcedly flow the ink in the ink return passage. The ink pump is configured to be driven in forward and reverse directions so as to change an ink flow direction. Since the shut-off valve intercepts forcedly the ink flow in the ink supply passage, the ink in the ink tank is prevented from flowing abnormally to the print head and leaking from the print head.
    • 一种喷墨图像形成装置。 喷墨图像形成装置包括具有多个用于喷射墨水的喷嘴的打印头,用于存储墨水的墨水罐,用于将墨水罐中的墨水供应到打印头的墨水供应通道,将墨水返回通道 将打印头中的墨水返回到墨水盒,安装在供墨通道中的调节器以调节供应到打印头的墨水流量,安装在墨水供应通道中的墨水盒和调节器之间的截止阀, 以拦截供应到调节器的墨水流量,以及安装在墨水返回通道中的墨水泵,以迫使墨水返回通道中的墨水流动。 墨水泵被配置为沿正向和反向驱动以改变墨水流动方向。 由于截止阀强制地拦截供墨通道中的墨水流动,所以防止墨水盒中的墨水异常地流到打印头并从打印头泄漏。

    • The present invention relates to a method for in vitro phosphorylation of TRAP derived from Staphylococcus aureus. In the present invention, the TRAP is first identified as a kinase that self-phosphorylates and is phosphorylated specifically in the presence of an oxidative metal ion such as iron, copper and zinc. Based upon this finding, a novel method for in vitro phosphorylation of purified TRAP is provided and also, a method for screening various chemicals and natural materials by using the above method is provided in order to select inhibitors against the TRAP phosphorylation. The inhibitors are expected to be applied for novel antibiotics of Staphylococcus aureus, because this TRAP phosphorylation is essential to infect Staphylococcus aureus. Therefore, the present invention can be widely used to develop novel drugs against Staphylococcus aureus and their resistant strains, in near future.
    • 本发明涉及来自金黄色葡萄球菌的TRAP的体外磷酸化方法。 在本发明中,首先将TRAP鉴定为在氧化金属离子例如铁,铜和锌的存在下自磷酸化并被磷酸化的激酶。 基于这一发现,提供了一种用于纯化TRAP的体外磷酸化的新方法,并且还提供了通过使用上述方法筛选各种化学品和天然材料的方法,以选择抗TRAP磷酸化的抑制剂。 预期抑制剂应用于金黄色葡萄球菌的新型抗生素,因为这种TRAP磷酸化对感染金黄色葡萄球菌至关重要。 因此,本发明可以在不久的将来广泛用于开发抗金黄色葡萄球菌及其抗性菌株的新型药物。
