For example, a first component may be termed a second component, and similarly a second component may be termed a first component.

Furthermore, when it is mentioned that a certain element is "connected" to another element, it may be directly connected to the other element, but it should be understood that another element may exist in the middle. On the other hand, it should be understood that certain components are not present. On the other hand, other expressions describing the relationship between elements, such as “between” and “between” or “neighboring to” and “directly adjacent to”, should be interpreted in the same way.

The singular expression is to be understood as including the plural expression unless the context clearly dictates otherwise, and terms such as “comprises” or “have” are not intended to be used as a reference to the specified feature, number, step, action, component, part, or these. It is intended to indicate that a combination exists, and it should be understood that it does not preclude the possibility of the existence or addition of one or more other features or numbers, steps, operations, components, parts, or combinations thereof.

As described above, although the present invention has been described with reference to limited embodiments and drawings, the present invention is not limited to the above-described embodiments, which are various modifications and variations from these descriptions by those skilled in the art to which the present invention pertains. Transformation is possible. Accordingly, the spirit of the present invention should be understood only by the claims described below, and all equivalents or equivalent modifications thereof will fall within the scope of the spirit of the present invention.
