BEST MODE FOR CARRYING OUT THE INVENTION The constitution and embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Patent Document 4: Application No. 10-2013-0010744, which is disclosed in kipris (patent search system). Title of the invention: Description of specific contents for carrying out the invention of water cap and fire extinguishing cap using air cap If you look,

Sterilized water, or toilet lotion, and the upper part of the upper layer or the lower part of the lower layer is provided with a non-woven fabric, a wet cloth, or a cotton cloth And then the absorbent article is absorbed into the tissue by using a hand cap,

Alternatively, a powder cap is made by filling the air cap with powder, and a powder cap made by filling the powder cap with fire powder is attached to the wall or ceiling of the building. When the fire capsize, the powder cap blows out, , It is necessary to secure the amount of water enough to wet the tissue in order to have a means to use it as a hygienic one-time wet tissue, so as to dissolve the water cap with the force of the hand and wet the tissue with a large amount of water, As a means for use, it is understood that each water cap is easily protruded by hand with a large protrusion so that the water cap can be opened by hand.

Also, in place of the water contained in the water cap, a powder cap filled with fire-extinguishing powder may be used to replace the wall of the building, or, when installed on the ceiling, A large amount of fire extinguishing powder can be used to extinguish the fire, and it can be seen that each of the powder caps is filled with a large amount of fire extinguishing powder as shown above.

In addition, food spices, sauces, or various kinds of colors can be filled in the internal space of the water cap 50, which can contain liquids, Or particles having a predetermined size or a powder containing a powder of stones can be filled and used according to the intended use.

According to Claim 1 of the patent,

In the air cap (40) in which the upper layer paper (20) is superimposed on and joined to the lower layer paper (10)

A water cap and a fire extinguisher cap which are filled with liquids including distilled water, sterilized water, or lotion and the like, are sealed in an inner space of the air cap 40,

In the above claims, the liquid containing distilled water, sterilized water, or lotion contained in the air cap (40) in which the upper layer paper (20) is superimposed on the two lower layer paper (10) The purpose of use is different, and most of all, it is sticky on one side of the mobile phone, or embossed structure which is thick and uneven and can not be stored like a card in a storage box of a mobile phone protective case, It can not be used as wallpaper, and can not be made into a transparent form.

Therefore, it is revealed that the electromagnetic wave absorbing sticker of the present invention described below is a completely different technique to the structure, function, and purpose of the present invention.

Electromagnetic waves are always present in the atmosphere where electronic equipment is used and in radio waves.

In addition, the use of cellular phones is becoming everyday, and is always exposed to electromagnetic waves.

In addition, when the mobile phone is used in a closed space such as a room, an elevator, a train or a bus, the intensity of the electromagnetic wave is increased by a factor of several times to several tens times, and the effect on the human body is great. .

When using a mobile phone, the intensity of the electromagnetic wave is 0.11-0.27 V / m during the connection, 0.08-0.24 V / m during the phone call, 0.03-0.14 V / m always in the atmosphere, When using a mobile phone, it is very high, 0.15 ~ 5.0V / m.

 Currently, medical devices and filters are used in limited applications.

Nanofibers are made by electrospinning. When a high-voltage electric field is applied to a polymer material, which is a raw material of nanofibers, an electric repulsive force is generated inside the material, and molecules are separated into nano-sized particles. The threads are torn apart and intertwined to form a nonwoven fabric-like nanofiber.
