Here, it should be noted that the description of the above technical solution is exemplary, and the present specification may be embodied in different forms and should not be construed as being limited to the technical solution set forth herein. Rather, these descriptions will be provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Furthermore, the technical solution of the invention is limited only by the scope of the claims.
The shapes, dimensions, ratios, angles, and numbers disclosed for describing aspects of the present specification and claims are merely examples, and thus, the present specification and claims are not limited to the details shown. In the following description, a detailed description of related known functions or configurations will be omitted when it may be determined that the emphasis of the present specification and claims is unnecessarily obscured.
Where the terms "comprising," "having," and "including" are used in this specification, there may be additional or alternative parts unless the use is made, the terms used may generally be in the singular but may also mean the plural.
