The present invention is not limited to the above examples, and various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
Here, it should be noted that the description of the above technical solutions is exemplary, the present specification may be embodied in different forms, and should not be construed as being limited to the technical solutions set forth herein. Rather, these descriptions are 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 present invention is limited only by the scope of the claims.
The shapes, sizes, ratios, angles, and numbers disclosed to describe aspects of the specification and claims are examples only, and thus, the 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 is determined that it unnecessarily obscures the focus of the specification and claims.
Where the terms "comprising", "having" and "including" are used in this specification, there may be another part or parts unless otherwise stated, and the terms used may generally be singular but may also refer to the plural.
It should be noted that although the terms "first," "second," "top," "bottom," "side," "other," "end," "other end," and the like may be used and used in this specification to describe various components, these components and parts should not be limited by these terms. These terms are only used to distinguish one element or section from another element or section. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, with the top and bottom elements being interchangeable or switchable with one another under certain circumstances, without departing from the scope of this specification; the components at one end and the other end may be the same or different in performance from one another.
In describing positional relationships, for example, when positional sequences are described as "on.. Above", "over.. Under." and "next", unless a word or term such as "exactly" or "directly" is used, cases where there is no contact or contact therebetween may be included. If a first element is referred to as being "on" a second element, that does not mean that the first element must be above the second element in the figures. The upper and lower portions of the component will change depending on the angle of view and the orientation. Thus, in the drawings or in actual construction, if reference is made to a first element being "on" a second element, this can include the case where the first element is "under" the second element and the case where the first element is "over" the second element. In describing temporal relationships, unless "exactly" or "directly" is used, the descriptions of "after", "subsequently", and "before" may include instances where there is no discontinuity between steps. The features of the various embodiments of the present invention may be partially or fully combined or spliced with each other and performed in a variety of different configurations as would be well understood by those skilled in the art. Embodiments of the present invention may be performed independently of each other or may be performed together in an interdependent relationship.
Finally, it should be noted that the above embodiments are merely representative examples of the present invention. It is obvious that the invention is not limited to the embodiments described above, but that many variations are possible. Any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present invention should be considered to be within the scope of the present invention.
