摘要:
On an inner circumference side of a stator fixed in an inner housing, a rotor is arranged. The rotor rotates through a bearing with respect to a center shaft that is a stationary shaft fixed to outer housings. Oil introduced into a rotor oil inlet path in the center shaft flows through a communication path and a clearance on an outer circumference of the center shaft into an oil path in the rotor. The oil flowing through the oil path cools a permanent magnet, lubricates the bearing, and is discharged from a rotor oil discharge port to the outside of the inner housing. The oil in the clearance is sealed with a thread seal, i.e., an inner thread formed in an inner face of an end ring and is prevented from flowing toward the bearing.

A rotary machine capable of carrying out efficient cooling without increasing costs or deteriorating performance is provided. A motor 1 serving as the rotary machine has a rotor 20 configured to be rotatable around a rotary shaft 10, a stator 30 having a stator core 31 arranged around the rotor 20 and a coil 32 attached to the stator core 31 so that a coil end part 32a protrudes from each end of the stator core 31, mold members 33a and 33b formed at both ends of the stator core 31, to cover base parts of the coil end parts 32a, and partition parts 42b and 43b attached in contact with the mold members 33a and 33b, to separate a space S1 in which the rotor 20 is arranged from a space S2 in which the coil end parts 32a are arranged.

A rotary machine capable of preventing leakage of a coolant and simply and efficiently cooling a rotor is provided. A motor 1 has a rotor 20 made by laminating magnetic steel sheets, a stator 30 arranged around the rotor 20, a rotary shaft 10 passed through a central part of the rotor 20, and an annular sleeve 27 arranged between the rotary shaft 10 and the rotor 20. On an outer circumferential face of the rotary shaft 10, a groove 12 serving as a coolant flow path for guiding a coolant is formed. The groove 12 may be formed only on the outer circumferential face of the rotary shaft 10, or only on an inner circumferential face of the sleeve 27, or on both the outer circumferential face of the rotary shaft 10 and the inner circumferential face of the sleeve 27.
摘要:
A fragrance composition which contains 1,3-dimethoxy-5-methylbenzene in an amount of from 0.01 to 30% by weight as a fragrance modifier that provides a sedative effect. 1,3-Dimethoxy-5-methylbenzene used in the present invention can exhibit a sedative effect not only by itself but also when mixed with various formulations of jasmine, floral and the like types having stimulative effects. Also, since a single chemical is used as an active ingredient, the present invention is more effective than the sedative function of natural essential oil from a viewpoint of sedation. In addition, since 1,3-dimethoxy-5-methylbenzene itself has a mild scent, its sedative effect can be obtained without altering original fragrance of interest.

The present invention relates to a beauty method in which a sound skin condition can be maintained or created and/or deep relaxation can be appreciated, wherein a comfort-stimulating means capable of acting on the mind is introduced in addition to a care cosmetic means.
摘要:
A skin barrier function recovery and promotion composition containing, as an active ingredient, a fragrance which is effective when evaluated by applying a predetermined stress to a model experimental animal, in a system to which the tested fragrance is not applied, to thereby reduce the skin barrier function of the animal and using this data of the degree of recovery of the skin barrier function as an indicator and evaluating the capability by the difference between this data and data of the degree of recovery of the skin barrier function in a system to which the tested fragrance is applied.
