DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below.

The drawings are merely one embodiment of the present invention, and are not limited to the illustrated examples at all, and can be arbitrarily changed within the scope of the present invention. In the figure, 1 is a conductive wire, M is an electric motor using the conductive wire 1, C is a kite-raising playground equipment using the conductive wire 1, A is an automobile antenna using the conductive wire 1, B indicates a mobile phone antenna (base station side) using the conductive wire 1, and D indicates a mobile phone antenna (mobile phone side) using the conductive wire 1. Also, a mobile phone referred to in this specification includes a PHS (Personal H).
and System).

The conductive wire 1 is made of, for example, a fibrous material, a synthetic resin material, a leather material, a nonwoven fabric, or the like in the form of a thin wire having a square cross section or a thin plate (not limited to a flat plate or a corrugated plate). Are formed on the wire body 2 and the conductive materials 3.
Is formed by forcibly penetrating or coating. Further, in the present embodiment, the outer surface of the wire rod body 2 in which the conductive material 3 is forcibly penetrated or applied is covered with the cover 4 (FIG. 1).

The reason why the wire main body 2 is square in cross section is that the cross sectional area is increased by about 30% as compared with the case where the wire main body 2 is circular in cross section, and the rate at which the conductive material 3 penetrates or is applied by that much. It is because it becomes high.

The material, shape, structure, length, and the like of the wire body 2 are not particularly limited, and well-known general materials and shapes are applied.

For example, the wire rod body 2 is made of a fiber material such as cotton or silk, a synthetic resin material such as nylon, polyester, or polyester made of Japanese paper, a leather material such as cowhide, snake skin, or a nylon, polyester, or Japanese paper. The non-woven fabric is formed into a thin line having a square cross section, and a single non-woven fabric or a plurality of the non-woven fabrics are formed by a known method such as twisting, knitting or weaving. In this embodiment, the thin linear body 2 having a square cross section is used.
Although a and 2a were formed by twisting two wires (see FIG. 1), a single wire or a twist of three or more wires is within the scope of the present invention. is there.

As the conductive material 3, a conductive material in the form of an ultrafine powder is used. For example, an aluminum ultrafine powder, a carbon ultrafine powder, a graphite paint ultrafine powder and the like are mentioned as typical conductive materials. Can be However, the above-described example is only one embodiment of the conductive material 3 used in the present embodiment, and is not limited at all as long as the material has conductivity.

It is to be noted that a conductive material 3 such as carbon fiber (not limited to short fibers or long fibers) is woven therein, or the conductive material 3 such as carbon fiber is used to form a wire main body into a thin line shape or a thin plate shape having a square cross section. 2 may be included.

The conductive material 3 is provided by forcibly penetrating or applying to the wire main body 2. More specifically, the conductive material 3 is provided as follows. However, it is only one embodiment and is not limited.

The conductive material 3 is directly applied to the fine craters (fine depressions) in the fibers 2a, 2a of the fiber material constituting the wire rod body 2 or in the surface of the synthetic resin material or the like. Apply and embed. Fibers into which the conductive materials 3 are kneaded are twisted to form the wire main body 2 in a thin wire shape or a thin plate shape. The wire rod body 2 is put in a vacuum vessel together with the liquid mixed with the conductive materials 3..., And external pressure is applied to the fibers 2 a, 2 a of the wire rod body 2, or the synthetic resin wire rod body or the like. Fine craters on the surface (fine depressions)
The conductive material 3 is forcibly infiltrated into the fiber, and then the liquid is evaporated or volatilized, so that the conductive material 3 is formed in the fine craters (fine depressions) in the fiber or on the surface of the synthetic resin wire body or the like. The state is embedded.

Further, the wire main body 2 is woven with conductive fibers.
When forming a conductive fiber, a well-known conductive fiber other than a carbon fiber can be used as the conductive fiber.

The cover 4 covers the entire outer periphery of the surface of the wire body 2 in which the conductive material 3 is forcibly penetrated or applied, or is coated with a vinyl chloride resin, enamel or the like, or is covered with a fine cloth such as silk. This prevents the conductive material 3 from peeling and falling.

Therefore, the conductive wire 1 of the present embodiment configured as described above can be used in various ways such as being used as a winding of an electric motor instead of a copper wire, or used as an antenna for an automobile. It is within the scope of the present invention as long as it is used by conducting.

In the following, specific examples will be described, but each is merely an example of the use of the conductive wire of the present invention, and the form of use within the scope of the present invention is not limited thereto. Absent. In the first to eighth embodiments, the conductive wire 1 is formed into a thin wire having a square cross section and two strands are twisted. In the ninth embodiment, the conductive wire 1 is used.
Are described in the form of a thin flat plate having a square cross section, respectively. However, the conductive wire 1 formed in a thin flat plate shape in the first to eighth embodiments is used, and a thin wire is formed in the ninth embodiment. May be used as needed within the scope of the present invention.

FIG. 2 shows an embodiment of a cage type induction motor M, and a winding 7 of the motor M is shown in FIG.
The conductive wire 1 is used in place of the copper wire (FIG. 2).
reference). In the figure, 5 is a stator portion, 6 is a stator yoke,
Reference numeral 8 denotes a rotor (cage rotor), 9 denotes an iron core, 10 denotes a rotating shaft, 11 denotes a short-circuit ring, and 12 denotes a bar.

The motor M is not particularly limited to the illustrated example, and any known motor using a copper wire, such as a DC motor, a stepping motor, or a brushless motor, is within the scope of the present invention.

That is, specifically, since the conductive wire 1 of the above embodiment can be used as the winding 7 instead of the copper wire widely used for the electric motor M as the winding, excellent cost reduction can be achieved and inexpensive. A simple electric motor M can be provided.

[Second Embodiment] FIG. 3 shows an embodiment of a kite-raising plaything C, which uses the conductive wire 1 as a kite-yarn 17, Has one end connected to a power supply side 14 and the other end connected to an electric motor 15 attached to an arbitrary portion of the kite, and a rotational force of the electric motor 15 rotates a propeller 16 to raise and float the kite. It is a lifting play equipment (see FIG. 3).

The kite string 17 is not particularly limited, and the conductive wire 1 shown in the present embodiment can be arbitrarily applied.

The kite body 13 for raising the kite is not particularly limited to the illustrated example, and its structure (material, shape, size, etc.) can be freely selected. That is, it may be in the form of a sheet made of paper, a sheet made of synthetic resin, or an inflatable body such as a balloon, and does not care about the general concept of a kite. Within range.

The type and location of the electric motor 15 are not particularly limited, and the location can be changed as necessary. Further, it is of course possible to use the electric motor M shown in the above embodiment. Also, the type and size of the power supply source 14 are not limited.

By using the kite-raising playground equipment configured as described above, a player such as a child can enjoy kite-raising play regardless of the presence or absence of wind. That is, in the kite raising that has been generally performed until now, a kite body tied with a cotton thread is raised by using the force of a naturally occurring wind to play. However, in recent years, it was not very interesting for children to play with raising a kite using only the power of the natural wind in this way, and if there was no wind, kite raising and play could not be realized at all.

Therefore, if the kite string 17 is formed of the conductive wire 1 of the present embodiment, the power supply source (in the present embodiment, the power supply source held by the player via the kite string 17 (1)). The electric motor 15 mounted on the kite body 13 and the electric motor 15 attached to the kite body 13 are energized.
Accordingly, the propeller 16 held rotatably rotates. The kite rises due to the rotation of the propeller 16, and a kite raising play can be performed. In addition, the propeller 16 is a motor 15
Is held rotatably directly or indirectly.

The function and effect are as described above, and the description is omitted. In the figure,
Reference numeral 18 denotes an automobile body, 19 denotes a car stereo, and A denotes an automobile antenna using the wire 1.

Conventionally, a retractable rod-shaped antenna is provided with a rod-shaped antenna that can be stored in a vehicle body so that it can be extended or contracted automatically or manually. In many cases, the antenna that was used hits the entrance or the like and breaks accidentally.

Therefore, the conventional telescopic antenna is stopped,
Such a conventional problem is solved by using the conductive wire 1 of the embodiment as the antenna A for a vehicle. That is, specifically, the conductive wire 1 of the above embodiment is formed into a desired diameter and a desired length, one end of the wire 1 is connected to a terminal of the car stereo 19, and the wire 1 is connected to an arbitrary position in the vehicle. And the other end is attached to an arbitrary portion such as a side glass or a rear glass to be used as the antenna A. As a result, it is safe without the inconvenience that the antenna is broken as a result of entering the garage with the antenna forgotten to be taken out as in the related art. Further, since the rod-shaped antenna projecting from the vehicle body as in the related art is not required, the external appearance design of the entire vehicle is also improved.

[Fourth Embodiment] FIG. 5 shows that the conductive wire 1 of the above-described embodiment is arranged along a track or a road.
Is used as a mobile phone antenna (base station side antenna) B. In addition, in the figure, 20 is a railway line, 21 is a tunnel, 22 is an electric wire and the like.

For example, conventionally, during high-speed traveling on a Shinkansen or a highway, almost all conventional mobile phones cannot communicate, and in some cases, communication cannot be made even in an emergency business. . This problem can be solved by running the antenna on the base station side along the tracks and roads.However, it is enormous to extend the antenna in this way. Could not be achieved in reality because of the high costs involved.

Therefore, the conductive wire 1 of the above-described embodiment formed to a desired diameter and a desired length can be crawled along a line or a U-shaped groove as a mobile phone dedicated antenna (base station side antenna) B, so that it can be used anywhere. It is assumed that a mobile phone can be connected with high sensitivity even during high-speed movement. The location along the antenna B of the present embodiment is not particularly limited, and can be changed as needed. According to the present invention, the main wire is made of inexpensive cotton or synthetic resin, and the conductive material is forcibly penetrated or applied to the main wire, so that it can be provided at a low cost and can be provided along the track and along the road. Even if it is enormous in length, it can be implemented in practice without any cost problems.

An example is shown in which the conductive wire 1 of the above embodiment is sewn into the curtain stopper 25a and the antenna (base station side antenna) B dedicated to a mobile phone is also used. In the figure, reference numeral 23 denotes a room in a building frame, 24 denotes a ceiling surface, and 25 denotes a curtain.

In a building, the connection of mobile phones is also reduced to prevent radio interference. In addition, although radio waves enter vertically, mobile phones are normally used at an angle of about 60 degrees, so conventional mobile phone antennas (mobile phone-side antennas) have a 60-degree angle, similar to the main body of mobile phones. It is in a state of being inclined to the extent. Therefore, it is in a state where radio waves cannot reach further.

Therefore, in order to solve such a problem, the conductive wire 1 of the above embodiment is used as a mobile phone dedicated antenna (base station side antenna) B as it is in the building frame room.
For example, by hanging from the ceiling surface 24 or sewn into the curtain stopper 25a or the like, the passage of radio waves is improved. Further, the antenna B may be directly sewn into the curtain 25. Specifically, the surface of the wire main body 2 formed as described in the above embodiment is coated with a coating agent (for example, FT3 manufactured by Tokyo Copal Co., Ltd.) and a cover 4 is provided to provide the conductive wire 1 (an antenna dedicated to a mobile phone). Construct B). The cover 4 prevents the conductive material from falling off and peeling off. The length and diameter of the conductive wire 1 are not particularly limited, and can be adjusted according to the location of the conductive wire.

[Sixth Embodiment] FIG. 8 shows an example in which the conductive wire 1 is incorporated into an imitation flower / tree 26 such as an artificial flower to be used as an antenna (base station side antenna) B dedicated to a mobile phone.

Conventionally, a mobile phone antenna (base station side antenna) is mounted on an electric wire, a telephone box, or the like, or is mounted on a ceiling of a building frame in a suspended state. There was a problem that spoiled the beauty of the cityscape. By using it as in the present embodiment, there is no risk of impairing the aesthetics of the room and the cityscape.

More specifically, the surface of the wire main body 2 formed as in the above embodiment is coated with a coating agent (for example, FT3 manufactured by Tokyo Copal Co., Ltd.), and a cover 4 is provided to form the conductive wire 1 (portable). A telephone antenna B) is constructed, the antenna B is incorporated in the trunk 27, and its tip 28
Are projected outside. The cover 4 prevents the conductive material from falling off and peeling off. The length and diameter of the conductive wire 1 are not particularly limited,
It can be handled according to the location where it is incorporated.

In the present embodiment, the imitation flowers / trees 26 are described using potted imitation bamboo. However, the imitation flowers / trees 26 are not particularly limited to the shape and structure, and the shape and structure do not impair the aesthetic appearance of the room or the streets. Are all within the scope of the present invention.

Further, a device (dedicated terminal: for example, a product "Pedco" manufactured by NTT Mobile Communication Network Co., Ltd.), which is generally used at present, can easily detect the approximate current location, and is used as an antenna of the device. It is of course possible to use the conductive wire 1 of the form. As a result, the product main body, which has a compact antenna body with a built-in antenna, can be further downsized. In addition, this embodiment can also be applied to ecology research of land and water animals. In other words, by wrapping or attaching the conductive wire 1 incorporating the transmitter to animals such as monkeys, birds, fish, etc., which are the subject of the ecological survey, it is possible to confirm and investigate the range of action and the time of action. it can.
