Description

Detailed Description of the Invention

    The present invention relates to a terahertz wave generating material and a terahertz wave comprising a terahertz wave generating composition in which the terahertz wave generating composition has enhanced permeability to an object by baked Sakurajima volcanic ash or the like in a silicon composition that generates terahertz waves. The present invention relates to a generating composition and a coaster.

The terahertz wave is a frequency band that oscillates from 100 billion times to 10 trillion times per second among electromagnetic waves. The terahertz band is a wavelength region that has both light wave straightness and radio wave transparency. In terms of wavelength, it is electromagnetic waves in the far-infrared to millimeter wave region from 25 μm (micrometer) to 10 mm. Among electromagnetic waves, high energy electromagnetic waves such as X-rays and γ-rays have a side effect of degrading and damaging cells. In contrast, terahertz wave energy is weak and harmless to the human body. However, when irradiated with terahertz waves, it is absorbed as vibrational energy of the molecule, and the cell membrane of the organism causes a resonance phenomenon, raising the body temperature, promoting the growth of animals and plants, and enhancing the vitality. Terahertz waves are electromagnetic waves that are radiated and absorbed simultaneously by all materials and living organisms in nature, such as animals, plants, and minerals. All natural substances such as animals, plants and minerals are composed of atoms and molecules. These molecules and atoms vibrate by absorbing the energy of nature and the universe as heat and light, and this vibration generates terahertz waves. Although the energy of terahertz waves emitted by all materials in nature is weak, it is said to be a life ray because it is involved in the properties of the material and is involved in all life activities.

On the other hand, far-infrared rays, which are well known from the past, are not permeable and permeable, but warm the skin,
It has the effect of promoting blood flow in capillaries and is said to be a growth beam. Far-infrared rays are used for heating inside materials and saving energy. A terahertz wave having a wavelength longer than that of far infrared rays is also referred to as super far infrared rays, which improves inorganic and organic properties and activates cellular genes (DNA). As a result, terahertz wave energy has the power to instantly improve the properties of a substance and to instantly improve or cure a disease. Moreover, the result of irradiating a substance or living body with a terahertz wave is generated instantaneously, so anyone can confirm the effect.

  The human body also emits a small amount of terahertz waves, but when the internal organs and body get tired, the emissivity decreases, and it is said that the amount of emission decreases with age. Complementing the reduced terahertz wave improves blood flow, activates the cells youthfully, and increases vitality. It is said to maintain health, improve incurable diseases such as cancer, and delay aging. Recently, the miraculous healing effect of terahertz waves for intractable diseases has been attracting attention in the medical community. It is said to be effective in healing cancer, diabetes, Alzheimer, Parkinson's disease, collagen disease, nephritis, progressive muscle atrophy, hypertension, heart disease and the like.

Difference between far-infrared and terahertz

As shown in the figure below, infrared rays (growth rays) are neither permeable nor permeable and do not penetrate the body. It is absorbed a little on the surface of substances and living organisms. However, it raises the temperature of the substance and promotes plant growth, but does not cause nanonization. It is said to be “growth light” and far infrared rays are used for heating the inside of the substance and for energy saving. In contrast, terahertz waves (life rays) have a longer wavelength than far infrared rays, and are also referred to as super far infrared rays. Terahertz wave energy is said to instantly improve the properties of substances and activate gene DNA. Because it controls life activities, it is said to be a “life light” line, and a nano phenomenon occurs. The terahertz wave is absorbed by the substance as the frequency increases (the wavelength decreases).

  For example, Patent Document 1 (Patent No. 3998328) discloses that “freshness characterized in that bamboo charcoal and tourmaline ore are contained, and a freshness-preserving agent is printed as a pattern on the surface of a sheet body made of water-absorbing pulp. A "holding sheet" is disclosed. According to the present invention, the adsorption of bamboo charcoal powder, which is a porous material, the deodorizing effect and the effect of maintaining the freshness due to the adsorption effect of electrostatic force of tourmaline ore has been completed, By mixing both, there is also a synergistic effect that the freshness retention effect of bamboo charcoal can be maintained semipermanently. That is, it is explained that static electricity is generated due to the property of electrode formation of tourmaline ore, which promotes the activation of bamboo charcoal.

  However, Patent Document 1 discloses an electromagnetic wave generating composition containing silica as a main component, as in the present invention, and the terahertz transmission spectrum reduces the transmittance in the frequency (THz) band to absorb the terahertz wave to the object. There is no description or suggestion of increasing the freshness retention effect of various foods placed on the sheet by neutralizing by suppressing excessive secretion of ethylene gas.

  Patent Document 2 (Japanese Patent Laid-Open No. 2015-002731) states that “resonant electromagnetic waves having a specific frequency are irradiated for a certain period of time under specific temperature conditions onto a material such as paper, cloth, plastic, metal, or ceramic. Thus, the material itself is used as a transfer body of the electromagnetic wave, the chip 63 or the seal or sheet of the transfer body is attached to the outside of the container 61 containing fresh food, and the material is used as the oscillation source of the electromagnetic wave. According to claim 2, the freshness-preserving material and its manufacturing method exhibiting the effect of preventing oxidative deterioration and preventing spoilage bacteria 70 without directly contacting food, wherein the specific frequency is 30 to 40 terahertz. The conventional method for maintaining the freshness of fresh food has a problem in food hygiene because most of the conventional methods for maintaining the freshness of food are in direct contact with the food. A method of maintaining freshness without directly contacting food with negative ions generated by lamic has been developed, but there was a problem in controlling spoilage bacteria. It provides a freshness-keeping material that exhibits the effect of repelling spoilage bacteria and a method for producing the same.

  However, Patent Document 2 simply states that “the material itself is irradiated with a resonance electromagnetic wave of 30 to 40 terahertz under a specific temperature condition on a material such as paper, cloth, plastic, metal, or ceramic. As described in the present invention, the terahertz transmission spectrum reduces the transmittance in the frequency (THz) band to increase the absorption of the terahertz wave into the object, thereby producing ethylene gas. There is no mention or suggestion of improving the freshness-maintaining effect of various foods placed on the sheet by neutralizing and suppressing excessive secretion.

By breaking the hydrogen bonds of the ingredients and lowering the molecular weight of the high molecular weight component, we will improve the taste felt in miso and provide a product that can easily improve the quality of a low-priced beverage. " "According to the present invention, it is possible to improve the quality of a low-priced beverage with a simple method, and to produce a highly effective and highly durable 32-38 terahertz resonance electromagnetic wave, which is highly versatile. A functional coaster according to the present invention can provide a functional coaster, and a drink such as water, alcoholic beverages and juice in a cup can be placed on the coaster without touching the beverage directly. The beverage can be radiated with 8 terahertz resonant electromagnetic waves, and the resonant electromagnetic waves resonately excite hydrogen bonds of moisture and components in the cup placed on the functional coaster, Then, electrons released from the hydrogen bonds move through the beverage at high speed, and collide with other atoms and molecules, so that a lot of electrons (negative ions) are released one after another in a cascade. The component is reduced in molecular weight, the redox potential is reduced, the PH value is alkalin, the moisture and the component are activated, and the resonance electromagnetic wave is also a hydrogen bond of an amino acid or other component having a hydrogen bond. Amino acids and other components that have been resonance-excited, have a low molecular weight, and have a low molecular weight are perceived as umami components in the miso so that the quality of alcoholic beverages and juice is improved. ” There.

  However, Patent Document 3 discloses that, as in the present invention, “... a terahertz transmission spectrum is placed on a sheet by lowering the transmittance in the frequency (THz) band to increase the absorption of a terahertz wave into an object. There is no description or suggestion about the point that can improve the taste of various foods.

  Further, Patent Document 4 (Japanese Patent Application Laid-Open No. 2004-321811) includes “a power supply unit 400; a heating plate 10 that generates heat upon receiving power supply from the power supply unit 400; and the heating plate 10; A laminated component 100 comprising a far-infrared radiation material box 20 in which various far-infrared radiation materials in powder or solid form are arranged in various forms, and a finishing member layer 40 provided on the far-infrared radiation material box 20.

  The invention of claim 7 provides a coaster in which a sheet coated with the terahertz wave generating composition is attached to natural grass.

  In this invention, since the sheet | seat which apply | coated the said terahertz wave generation composition to natural grass is bonded together, unlike the natural grass, the sheet woven fabric has a porous (porous) structure. It has various functions and features such as high water absorption and high moisture retention.

Also, the drinks placed on this coaster have a mild taste, and those with a strong acidity, such as lemon, have a sour taste. In addition, carbonated drinks have fine foamy bubbles. Therefore, it is an optimal material for infiltrating the terahertz wave generating composition of the present invention. The same effect can be expected not only for coasters but also for general natural tatami mats.

  First, Sakurajima volcanic ash having an average particle size of 90 mesh was fired at 600 to 1100 ° C. in an electric furnace. The electrical resistance value of the baked Sakurajima volcanic ash is measured with an insulation resistance meter (HIOKI 3451) and shown in Table 1. In addition, the state of cockroaches when Sakurajima volcanic ash at each resistance value was put into a bug cage with cockroaches was shown.

  Next, terahertz wave generating compositions were prepared at the ratios shown in Table 2, and the following tests were performed at the respective ratios. Sakurajima volcanic ash used was fired at 800 ° C. For each sample, insect repellent effect: whether mites, termites, aphids are brought together. Umami improving effect: Shochu was drunk after 10 minutes on the coaster. Evaluate with ○ and * in the effect column in the table. * Mark is outside the scope of the present invention.

  From Table 2 above, it is understood that a terahertz wave generating composition comprising 42 to 47 wt% of black silica, 25 to 30 wt% of calcined Sakurajima volcanic ash, 5 to 8 wt% of tourmaline, and other 15 to 28 is particularly effective. However, claims 2 and 3 of the present invention are terahertz wave generating compositions containing black silica 40 to 48 wt%, calcined Sakurajima volcanic ash 16 to 32 wt%, tourmaline 4 to 12 wt%, and other 8 to 40 ranges, The results in Table 2 confirm this.

  The terahertz wave generating composition of sample number 5 shown in Table 2 above was dissolved in water and a plant-based adhesive and applied to a nonwoven sheet. The result of having performed the terahertz spectroscopic analysis about this silica coating sheet and the simple nonwoven fabric which has not apply | coated silica is shown in FIG.1 and FIG.2.

    As can be understood from FIG. 1, the terahertz transmission spectrum of the silica-coated sheet has a transmittance of approximately 70% to 10% in a frequency (THz) 0.4 to 3.5 (wavelength 750 to 86 μm) band. On the other hand, as can be understood from FIG. 2, the terahertz transmission spectrum of a simple nonwoven fabric not coated with silica has a transmittance of 100% in a frequency (THz) 0.4 to 3.5 (wavelength 750 to 86 μm) band. ~ 40%. That is, as the silica-coated sheet has a lower transmittance (%) from a lower frequency to a higher frequency (longer wavelength to shorter wavelength), it means that the terahertz wave can be more absorbed by the substance. Therefore, when the frequency (THz) of the silica-coated sheet increases, the transmittance (%) approaches 0% and the absorption of terahertz waves increases, whereas a simple nonwoven fabric not coated with silica has a high frequency (THz). Then, it is understood that the transmittance (%) is still about 40% and the absorption of the terahertz wave is not insufficient.

Supplement on transmission measurements of terahertz waves

The ratio of transmitted light intensity to incident light intensity is as follows.
The amount of infrared rays radiated from an object largely depends on the material and surface state (such as unevenness) of the object. In describing emissivity, there is a concept of “black body”. A “black body” is an ideal object that absorbs any wavelength incident on its surface and does not reflect or transmit. On the other hand, a real object has reflection and transmission to some extent. Therefore, the ratio of the ideal total radiant energy W based on the black body and the energy W ′ radiated by the object is calculated. This ratio is called emissivity and is usually expressed as ε.
The emissivity is an intrinsic constant related to the measured object, and is defined as a value between 0 and 1 where 1 is the ideal black body and 0 is the perfect reflector. There is Kirchhoff's law for this. When the material is in thermal equilibrium, the total emissivity is equal to the total absorption. When a substance absorbs light and the temperature rises or infrared rays are emitted and the temperature falls, the total emissivity and the total absorption rate are not equal.

In the measurement of the transmittance of the terahertz wave, since incident light is applied perpendicularly to the sample, it is considered that [100−transmittance] is an absorptivity when not much reflected light is emitted. Therefore, it can be said that a sample having a low transmittance has a high emissivity.

Freshness retention effect

Silica-coated sheet FIG. 3 shows the corroded state on the 9th day of tomato (left) placed on the silica-coated nonwoven fabric of Sample 5 in Table 2 and tomato (right) not placed on the silica-coated nonwoven fabric. . As can be understood from these, the tomato placed on the silica-coated non-woven fabric (left) is not corroded at all, while the tomato that is not placed on the silica-coated non-woven fabric (right) is aged and considerably corroded. I understand that. Vegetables and fruits produce ethylene gas as a mature hormone. This ethylene gas ripens vegetables and fruits and ages and rots. It is considered that the silica-coated sheet has micropores derived from the raw materials, and these micropores adsorb ethylene gas molecules to prevent ripening and aging of vegetables and fruits.

  Moreover, FIG. 4 compared the tangerine which was placed on a silica-coated nonwoven fabric for 9 days and FIG. 5 was compared with the tangerine which was placed on a silica-coated nonwoven fabric for 9 days. As can be understood from these results, it is apparent that the oranges placed on the silica-coated nonwoven fabric are not corroded at all, whereas the oranges not placed on the silica-coated nonwoven fabric are aged and considerably corroded. Like these tomatoes, these mandarin oranges and fruits produce ethylene gas as mature hormones. This ethylene gas ripens vegetables and fruits and ages and rots. It is considered that the silica-coated sheet has micropores derived from the raw materials, and these micropores adsorb ethylene gas molecules to prevent ripening and aging of vegetables and fruits. Furthermore, when the mandarin orange put on the silica-coated nonwoven fabric was eaten, the acidity was suppressed and the taste was mellow.

  The terahertz wave generating composition of sample number 5 shown in Table 2 above was dissolved in silica water and a plant-based adhesive and applied to a non-woven sheet to prepare a sleep sheet. FIG. 6 shows data of the sleep state by the smartphone “Sleep Meister” when the sleep sheet is used, and FIG. 7 shows the sleep state when the sleep sheet is not used. As can be understood from FIG. 6, there are many deep sleep states when the sleep sheet is used, but when the sleep sheet is not used as understood from FIG. 7, the sleep state remains shallow. Understood. In addition, (1) snoring became smaller. (2) Blood flow improved and waking was refreshed. (3) My body got lighter. (4) My back pain disappeared. (5) Now I can get up from the morning futon. ▲ 6 ▼ The number of times I go to the toilet in the night has decreased. (7) Results such as no longer waking up at night.

  Further, the terahertz wave generating composition of the same sample number 5 was dissolved in silica water and a plant-based adhesive and applied to the nonwoven sheet 1 and pasted between the coasters 2 and 3 on the coaster 2 shown in FIG. . As for the umami improvement effect, when the water split of shochu was drunk after 10 minutes on the coaster, the pungent taste of shochu became mellow.

  In addition, the effect of grilled fish on silica nonwoven fabric was investigated. When considering the use of silica non-woven fabric in grilled fish, considering the heat resistance of the non-woven fabric, it was considered to be about 230 ° C. From this, the temperature at which the fish was baked was baked at a temperature of about 200 ° C. It is said that it is better to bake fish in medium heat for a short time. If it is a high fire, the surface will be burnt, and if it is exposed to a low heat for a long time, the moisture and flavor inside will escape. By using silica non-woven fabric, the fire from the heat source of the grill was prevented from directly hitting the fish (to prevent scorching), and the terahertz wave re-radiated from the silica non-woven fabric heated from the inside of the fish and became a delicious grilled fish.

  We also examined the reduction of back pain. In the case of low back pain due to poor circulation, etc., it may be improved by warming, but it must be cooled if inflammation such as tight waist is occurring. When the surface of the silica non-woven fabric is turned inside and wound around the waist, terahertz waves from there penetrate into the waist, so that the waist is warmed, blood flow is increased, and back pain is improved Conceivable. There are various causes of low back pain, but there are many cases where the cause is not clear even when examined in a hospital. The national government formulated the “Back Pain Medical Care Guidelines” in 2012 as a countermeasure, and is taking a new approach to back pain treatment. The “Back Pain Clinical Practice Guidelines” state that hyperthermia is effective in the short term for acute and subacute back pain.
