    • The present invention relates to a system and method for detecting the remaining amount of a precursor in a vessel during a chemical vapor deposition (CVD) process. More particularly, the inventive system and method allow accurate measurement of the liquid level of the precursor remaining in the vessel during the CVD process by analyzing signals obtained by transmitting/receiving an ultrasonic wave. Thus, according to the present invention, the liquid level of the precursor can be measured in real time by means of an ultrasonic level sensor, thus preventing damages caused by the exhaustion of the precursor, resulting in a remarkable reduction in inferior products. Also, based on the above measurement results, the optimal replacement time of the precursor can be determined, thus extending the use period of the precursor to the maximum.
    • 本发明涉及用于在化学气相沉积(CVD)工艺期间检测容器中前体的剩余量的系统和方法。 更具体地,本发明的系统和方法允许通过分析通过发送/接收超声波获得的信号来精确地测量CVD过程中保留在容器中的前体的液面。 因此,根据本发明,可以通过超声波液位传感器实时测量前体的液面,从而防止由前体的耗尽引起的损害,导致劣质产品的显着减少。 此外,基于上述测定结果,可以确定前体的最佳置换时间,从而将前体的使用期延长至最大。

    • A method for manufacturing sharp spine-shaped projections on ceramic includes forming projections by applying a first soil water on the outside of the half-dried ceramic, forming projection roots; and growing projections by applying a second soil water on a plurality of the projection roots fifty to one hundred times using the brush and letting the projections dry at 15˜20° C., and 60˜70% of relative humidity for 15˜25 minutes in the shade after the application. Bright and mysterious various ceramic patterns are achieved by controlling water content of a first soil water to control projections density, controlling the number of a second soil water applications to control projections' size, selecting the direction of applications to form projections bent toward various directions and mixing pigments with soil water at proper time with proper mixing ratios to form projections with various colors.
    • 用于在陶瓷上制造锋利的脊柱形突起的方法包括通过在半干陶瓷的外侧施加第一土壤水而形成突起根而形成突起; 通过使用刷子在多个投影根上施加第二土壤水50〜100次并使突出部在15〜20℃,相对湿度为60〜70%干燥15〜25分钟的情况下生长投影 在申请后的阴凉处。 通过控制第一土壤水的含水量来控制投影密度,控制第二土壤水分的数量来控制投影尺寸,选择应用的方向以形成向各个方向弯曲的投影来实现明亮和神秘的各种陶瓷图案,以及 在适当的时间用适当的混合比将颜料与土壤水混合,形成各种颜色的投影。
