DETAILED DESCRIPTION OF THE INVENTION
[First Embodiment] Carbon powder (60 weight percent) made of charcoal that has been subjected to high-temperature compression treatment at 1600 degrees C. and sepiolite (40 weight percent) are mixed, and a cylinder having a diameter of 1 cm (cavity diameter of 5 mm) is subjected to high pressure. Obtained by molding with an extrusion molding machine, this was cut into 15 cm, dried, and then fired at 800 ° C. with oxygen-free lumps to obtain a cylindrical outer packaging body 1 of a ballpoint pen as shown in FIG. . Various effects on the body shown below were confirmed by the extreme use of the ball-point pen of the present invention (hereinafter referred to as a product) constructed using the cylindrical exterior body 1.
[0010]
(A) In the body temperature rise product, as shown in FIG. 2, the finger temperature started to rise after the start of use, and continued to rise after 20 minutes (x1). This is due to the infrared radiation effect of the product. On the other hand, in a ballpoint pen using a conventional plastic cylindrical outer casing (other members are configured using the same products as those of the product, hereinafter referred to as a conventional product), as shown in FIG. Furthermore, the increase was saturated after 10 minutes (x2) after use. In this way, the product warms the fingertip by raising the finger temperature smoothly, and creates a suitable feeling of use by warming the finger pot. In addition, when a facial thermograph was obtained and verified following the facial temperature, it was confirmed that the temperature rise of the product was more remarkable than that of the conventional product at the point of 16 minutes, and this increase in facial temperature also caused an increase in finger temperature. Produces a suitable sense of use as well.
[0011]
(B) In the carotid artery blood flow increase product, as shown in FIG. 4, the carotid artery blood flow once increased immediately after use, and the blood flow gradually increased after 15 minutes (x3). Thus, the product also functions to improve blood circulation. On the other hand, in the conventional product, as shown in FIG. 5, an increase in blood flow as in the product could hardly be confirmed. The effect of increasing the carotid artery blood flow of the product here is also presumed to be the result of dilation of the blood vessel as the temperature rises due to far-infrared radiation.
[0012]
(C) In the product for promoting blood circulation, as shown in FIG. 6, the R point potential in the electrocardiogram rises at the start of use and then decreases for about 7 minutes (x4), but thereafter rises to 15 minutes ( After x5), it returned to the original state and then became higher than when it was first used, and the height continued even after use. In the conventional product, as shown in FIG. 7, an increase in the R-point potential could not be confirmed during use. The R point potential decreases when the sympathetic nerve becomes active, and increases when the parasympathetic nerve becomes active. Activation of the parasympathetic nerve is promoted by blood circulation. Therefore, when this product is used, the parasympathetic nerve becomes active, so that a relaxed state of the body can be obtained. The performance of the product here is also presumed to be a result of the blood vessels being dilated as the temperature rises due to far-infrared radiation.
[0013]
(D) Increase in blood oxygen concentration As shown in the graph of FIG. 8, the product showed an increase in blood oxygen concentration after 5 minutes of use (x6), and an increase in oxygen concentration even after use. It was. On the other hand, in the conventional product, as shown in the graph of FIG. 9, an increase in oxygen concentration as in the product could not be confirmed. The performance of the product here is also due to the fact that blood vessels are enlarged as the body temperature rises due to far-infrared radiation, and blood circulation is promoted. As a result, the cardiopulmonary function and the metabolic function of the body are promoted when the product is used compared to the conventional product.
[0014]
(E) Stable skin resistance value The skin resistance value is the reciprocal value of the value in the graph of FIG. 10, and a smaller value on the graph indicates a larger resistance value. In the product, the resistance value does not change so much for about 15 minutes (x7) after use, and the skin resistance value is stable at a large value, which leads to a relaxed state of mind and body while the parasympathetic nerve is working strongly. On the other hand, in the conventional product, as shown in FIG. 11, many pulses are generated, and the skin resistance value is lowered. This is a state where the sympathetic nerve is working strongly and leads the body and mind to a stress state. . The performance of the product here is also due to the fact that blood vessels are enlarged with the increase in body temperature due to far-infrared radiation, and blood circulation is promoted. In addition, it is estimated that it is due to the perspiration action accompanying the temperature rise by the far-infrared radiation | emission of a product that a pulse generate | occur | produces in 15 minutes and a skin resistance value falls in a product.
[0015]
(F) Demonstrating a deodorizing function A 5 g sample piece obtained by cutting a product is placed in a glass container having an internal volume of 11 liters and a gas stirring device at the bottom so that the gas concentration in the container becomes a predetermined concentration. An appropriate amount of high concentration gas was injected. And the residual gas density | concentration was measured for every predetermined time after stirring. As a result, it was confirmed that the product exhibited the following odor component adsorption performance.
[0016]
The initial concentration of 10 ppm for formaldehyde adsorption decreased to 6 ppm after 30 minutes, 5 ppm after 60 minutes, and 3 ppm after 120 minutes.
[0017]
The initial concentration of acetaldehyde adsorption performance of 10 ppm decreased to 7 ppm after 30 minutes, 5 ppm after 60 minutes, and 3 ppm after 120 minutes.
[0018]
The initial ammonia adsorption performance concentration of 100 ppm decreased to 50 ppm after 10 minutes, 35 ppm after 30 minutes, 25 ppm after 60 minutes, and 5 ppm after 120 minutes.
[0019]
As described above, the product exhibits a deodorizing function, so that it can be used comfortably without causing odor even if dirt such as sweat adheres during use.
[0020]
(G) Other functional products contain carbon powder that has been treated at high temperature, resulting in good electrical conductivity. As a result, harmful static electricity can be removed from the human body by using it, and the function of shielding harmful electromagnetic waves can be achieved. Demonstrate. By having an electromagnetic wave shielding function, for example, if the product is worn in a breast pocket of clothes, the influence of electromagnetic waves on the heart can be eliminated.
[0021]
Second Embodiment Carbon powder (20 weight percent) made of charcoal that has been subjected to high-temperature compression treatment at 800 ° C. is heated and mixed with polypropylene resin (80 weight percent) to form a cylinder having a diameter of 1 cm (cavity diameter of 5 mm). Molded with a high-pressure extrusion molding machine, this was cooled and cut into 15 cm, and a cylindrical pendulum body 1 of a ballpoint pen as shown in FIG. 1 was obtained. And the ball-point pen was created similarly to the case of 1st Embodiment using this cylindrical exterior body 1. FIG. In this product, various performances and deodorizing functions associated with far-infrared radiation in the product of the first embodiment were similarly confirmed.
[0022]
