In order to provide a rubber composition in which dispersibility of silica is improved and in which a viscosity of an unvulcanized rubber is lowered and a heat build-up improving effect of a vulcanized rubber is well exerted, and a tire prepared by using the rubber composition, the rubber composition is endowed with a constitution in which 100 parts by mass of at least one rubber component selected from natural rubber and/or diene base synthetic rubbers are compounded with 55 to 200 parts by mass of silica and 0.5 to 15 parts by mass of at least one of alkanolamines represented by the following Formula (I): [in Formula (I), Rrepresents an alkyl group or an alkenyl group having 1 to 24 carbon atoms, and the above alkyl group and alkenyl group may be any of a linear group, a branched group and a cyclic group; m and n represent an average addition molar number, and m and n are numerical values which represent m+n=1 to 20].

Rubber composition and tire using the same

The present invention is a method for manufacturing a rubber composition containing a rubber component, a resin, a reinforcing filler and a crosslinking agent, and the method contains: a first step of adding the resin to the rubber component to produce a master batch; a second step of kneading the master batch with the reinforcing filler to produce a filled master batch; and a third step of kneading the filled master batch with the crosslinking agent, thereby providing a rubber composition having higher elasticity and large breaking elongation.

A space is set substantially in a tropical rain forest type environment to activate a human's essential brain region and realize an environment suitable for the human's brain by arranging a device for setting the tropical rain forest type environment based on characteristics of activating human's essential brain region responsive to tropical rain forest type environment information, in a space such as an urban space, a housing space or other living space. The tropical rain forest type environmental information has higher density and higher complexity than those of urban space type environmental information, and includes at least one of auditory information, visual information, and super perceptual information of aerial vibration. The tropical rain forest type environmental information is comfortable for the human with no excessive stress, and is environmental information for effecting prevention and treatment of diseases due to stress by realizing the environment comfortable for the human's brain.

A means is provided for generating a vibration or a vibration signal, which contains audible range components that are vibration components in the audible frequency range and super-high-frequency components within a range exceeding the audible frequency range up to a predetermined maximum frequency, and which has an autocorrelation order represented by at least either one of a first property and a second property. By applying the vibration or an actual vibration generated from the vibration signal to a human being, a fundamental brain activation effect activating the fundamental brain network system constituted of a fundamental brain including the brain stem, thalamus and hypothalamus that are regions to bear the fundamental function of the human being and the fundamental brain network of neuronal projection from the fundamental brain to various brain regions is introduced.

In a sound generating apparatus, a sound generating space, a sound, and a method for generating a sound, a sound is generated which has a frequency within a first frequency range beyond a predetermined audible frequency range and up to a predetermined maximum frequency, and which is non-stationary so as to change in a micro-temporal area in a second frequency range beyond 10 kHz. Then, the generated sound is applied to a person, thereby increasing cerebral blood flows of the person. This causes improvement and enhancement of the person's state of mind and body, so as to relieve stresses, thereby relaxing the person.
