Abstract: A deposition apparatus includes a shutter storage unit which is connected to a processing chamber via an opening and stores a shutter in the retracted state into an exhaust chamber, and a shield member which is formed around the opening of the shutter storage unit and covers the exhaust port of the exhaust chamber. The shield member has, at a position of a predetermined height between the opening of the shutter storage unit and a deposition unit, the first exhaust path which communicates with the exhaust port of the exhaust chamber.

Abstract: It is an object of this invention to prevent a deposited film from adhering to an exhaust chamber so as to suppress the generation of particles. A sputtering apparatus (1) includes a shutter accommodation unit (23) which is detachably placed in an exhaust chamber (8) and accommodates a shutter (19) in a retracted state, and shield members (40a, 40b) which at least partially cover the exhaust port of the exhaust chamber (8), and are at least partially formed around an opening portion of the shutter accommodation unit (23).

Abstract: Disclosed is a method for producing an alicyclic alcohol represented by general formula (III) which is useful as a starting material for a flavor mixture or the like at low cost in high yield. The alicyclic alcohol represented by general formula (III) is produced by preparing a cyclohexanecarbonyl compound represented by general formula (II) through the carbonylation of an unsaturated hydrocarbon represented by general formula (I) (preferably a compound obtained through the partial reduction of a diene compound) using carbon monoxide in the presence of HF, and thereafter reducing the cyclohexanecarbonyl compound. In formulae (I), (II), and (III), R1 represents an alkyl group having 1 to 4 carbon atoms, R2 represents an alkyl group having 1 to 4 carbon atoms, R3 represents an OH group, fluorine, or an OR4 group, and R4 represents an alkyl group having 1 to 4 carbon atoms.

Abstract: The present invention relates to a perfume composition as a raw material of fruity perfumes which has a conventionally unknown peculiar fresh, woody, floral, grassy-leafy nuance and is capable of harmonizing with various perfumes to provide perfume preparations having a more sophisticated odor or scent. The perfume composition of the present invention includes a compound represented by the general formula (I): wherein R1 and R2 are each independently a hydrocarbon group having 1 to 4 carbon atoms; and R3 is a hydrocarbon group having 2 to 4 carbon atoms.
