摘要： A metallic implant base is coated with two bioactive ceramic layers. An inner bioactive ceramic layer is coated on the implant base. An outer bioactive ceramic layer is coated on the inner bioactive ceramic layer. The inner bioactive layer is vitrified at a ratio of not less than 50 volume percent, thereby improving the bonding of the inner bioactive layer to the metallic implant base and preventing migration of the metal ions from the metallic implant base. The outer bioactive ceramic layer is vitrified to a ratio of substantially less than 50 volume percent, thereby providing a desired porosity.

摘要： A monocrystal rod utilized for producing the semiconductor device or solar cell includes a neck section, a main rod section and a shoulder section. The neck section is smaller in diameter than a seed crystal. The main rod section is formed integrally with the neck section and is larger in diameter than the neck section. The shoulder section is tapered for linking the neck section to the main rod section. The main rod section has a stopper section at the top portion of the main rod section, and the stopper section is larger than the main rod section.Also, an apparatus for preparing the monocrystal rod has a safety member for supporting upward the stopper section of the falling monocrystal rod.Further, a method of preparing the monocrystal rod includes the steps as follows. The seed crystal is pulled out from a melt in a crucible while rotating it. The speed of pulling the seed crystal is at first increased to grow the neck section whose diameter is smaller than the seed crystal, and then is gradually decreased to grow the shoulder section. Subsequently, the pulling speed is increased again so as to prevent further increase in diameter to grow the stopper section at the lower end of the shoulder section or at the top portion of the main rod section, and then is decreased again to grow the main rod section whose diameter is equal to a required diameter.
摘要翻译：用于制造半导体器件或太阳能电池的单晶棒包括颈部，主棒部和肩部。颈部的直径小于晶种。主杆部与颈部一体形成，直径大于颈部。肩部是锥形的，用于将颈部部分连接到主杆部分。主杆部在主杆部的顶部具有止动部，止动部大于主杆部。此外，用于制备单晶棒的装置具有用于向上支撑下降的单晶棒的止动部分的安全构件。此外，制备单晶棒的方法包括以下步骤。在将坩埚旋转的同时，从坩埚中的熔融物中取出晶种。首先增加拉晶种的速度，使其直径比晶种小的颈部生长，然后逐渐减小以使肩部生长。随后，再次提高牵引速度，以防止直径的进一步增加，使得在主体部分的下端处或主杆部分的顶部处的止动部分生长，然后再次减小以使主杆其直径等于所需直径。
