Abstract: A cooling agent composition includes a methyl menthol derivative represented by the following general formula (1). In the formula (1), a symbol * indicates an asymmetric carbon atom, X represents a hydrogen atom or a substituent, and Y represents an aryl group having 6 to 20 carbon atoms which may have a substituent.

Abstract: The present invention aims to provide a novel compound useful as a perfume material and a perfume composition containing the same, as well as a perfumed product. The present invention provides a compound represented by the following general formula: wherein R1, R2, R3 and R4 are each independently a hydrogen atom or a methyl group, Y1 and Y2 are each independently —O—CO—Z, —O—CO—O—Z or the like, Y3 is —O—CO—Z3, where Z and Z3 are each a linear or branched alkyl group containing 1 to 5 carbon atoms or a cycloalkyl group containing 3 to 5 carbon atoms or the like, and n is 2 or 3, and a perfume composition containing the same, as well as a product perfumed with the composition.

Abstract: A stator core of a motor arrangement includes six cores, which are arranged one after another in a circumferential direction. A bobbin, which is made of dielectric resin, is fitted to each core. Each coil is formed such that a winding is wound around the bobbin through a concentrated winding technique. Dielectric resin is filled between each circumferentially adjacent two teeth to cover each coil. Furthermore, the dielectric resin is molded to form clearances, each of which is formed between the corresponding circumferentially adjacent two teeth on a rotor side. Fuel, which is pressurized by a pump arrangement, passes an interior of the motor arrangement through a fuel passage, which is a gap between an inner peripheral surface of the stator core and an outer peripheral surface of the rotor, and also through the clearances.

Abstract: A fuel pump mounted in the fuel tank for the motor cycle comprises a motor and a pump driven by the motor for increasing a pressure of the sucked fuel. The motor is a brushless motor and has a stator core, coils and a rotor. An electrical energization for the coils wound around the stator core is controlled in response to a rotating position of the rotor, thereby the rotor is rotated. The rotor has a shaft, a rotating core and a permanent magnet, and the rotor is rotatably mounted at the inner circumference of the stator core. The permanent magnet is mounted at the outer circumference of the rotating core and magnetically energized so as to form magnetic poles different alternatively in a rotating direction at the outer circumferential surface facing the stator core.
