A multicylinder internal combustion engine E has a cylinder head 2; a cylinder head cover 3; an intake manifold 20 having a header body 21 disposed right above an engine body and intake runners 22; and a resonator 50. Each of the intake runners 22 has a bend 24 extending away from cylinder axes L in a longitudinal direction A2 perpendicular to the cylinder axes L, and curving so as to extend reversely toward the cylinder axes L. The resonator 50 is disposed opposite to the engine body with respect to the intake manifold 20 and is nearer to the cylinder axes L than outermost end parts 24a of the bends 24. The engine including the in take manifold and the resonator can be formed in a small dimension with respect to a longitudinal direction perpendicular to the cylinder axes, and the resonance chamber of the resonator can be easily formed to have a necessary volume.

In an automotive vehicle in which an air duct which forms an air guide passage for guiding air that has flowed into an engine compartment to an induction system of an internal combustion engine is provided integrally on an inner surface of a bonnet, a reduction in size and weight of the air duct and a compact disposition of the air duct within the engine compartment are attempted to be realized.An automotive vehicle includes an internal combustion engine 20 which is disposed within an engine compartment and an air duct 40 which is provided integrally on an inner surface of a bonnet 10. The air duct 40 forms an air guide passage 60 for guiding air that has flowed into the engine compartment to an induction system 20i of the internal combustion engine 20 between itself and a bonnet portion 30 which constitutes part of the bonnet 10 in cooperation with the bonnet portion 30. Because of this, the air duct 40 is a duct having an open section in which an edge portion 44 which is brought into abutment with the bonnet portion 30 in such a state that the air duct 40 is attached in place forms an opening along the air guide passage 60.

Provided are: tofu-like food and soy milk containing fibrous material, each of which has good texture and flavor and enables simultaneous intake of almost all of nutritional components in soybeans, such as proteins, lipids, glucides, fibrous material, minerals, vitamin components, and isoflavone compounds. Also provided is a process for producing soy milk containing fibrous material, which comprises the steps of: (A) dissolving and dispersing dehulled soybean powdery material having a nitrogen solubility index of 75 to 90, a lipoxygenase value of 30 to 120, an n-hexanal content of 0.5 ppm to 2 ppm, and a peroxide value of 0.2 meq/kg to 3.0 meq/kg in water to obtain dispersion; (B) subjecting the dispersion to heat treatment at 120° C. to 160° C. for 1 to 600 seconds; and (C) after the step (B), cooling the dispersion to 100° C. or lower and subjecting the resultant dispersion to emulsification and dispersion treatment under a pressure of 25 MPa to 200 MPa to produce soy milk containing fibrous material.

The method for producing a material loaded with gold nanoparticles, includes: impregnating a carrier with an anionic gold-hydroxo complex solution including a transparent solution that has a pH of not lower than 8, does not contain a halide anion, and contains a conjugate base of a weak acid not coordinated to gold and an anionic hydroxo complex of trivalent gold having a square planar molecular geometry whose at least one ligand is OH− and not containing a halide anion as a ligand; removing water; heating; and washing with water. According to the method, in a method for preparing a gold nanoparticle catalyst using a liquid phase method, a gold compound not containing a halide such as chloride is used as a raw material, and the gold compound can be supported efficiently. Furthermore, a gold nanoparticle-loaded catalyst having high activity can be obtained through a simple preparation method.

Novel modified lithium aluminum hydride type reducing agents obtained by reacting one equivalent of lithium aluminum hydride with one equivalent of an optically active N-substituted ephedrine of the formula, ##STR1## (wherein R.sub.1 is a C.sub.1 -C.sub.4 alkyl group or benzyl group, and Ph is phenyl group)and two equivalents of an N-substituted aniline of the formula, ##STR2## (wherein R.sub.2 is C.sub.1 -C.sub.4 alkyl group or phenyl group, and Ph is phenyl group).This reducing agent is usable for reducing the organic compounds having a carbonyl group (ketone group or aldehyde group) in their structure into the corresponding alcohols. It is particularly useful as a reducing agent for asymmetrically reducing the unsymmetrical ketones to selectively produce either an alcohol in which the asymmetric carbon atom bonded to the hydroxy group is in R-configuration or an alcohol in which said asymmetric carbon atom is in S-configuration.

A method of producing a composite nanoparticle (M-AxOy), having: generating, in an inert gas, an alloy (A-M) nanoparticle, which contains 0.1 at. % to 30 at. % of a noble metal (M), with the balance being a base metal (A) and inevitable impurities, and which has a particle size of 1 nm to 100 nm, to heat the alloy (A-M) nanoparticle and to bring the alloy (A-M) nanoparticle into contact with a supplied oxidizing gas during transportation of the alloy (A-M) nanoparticle with the inert gas, to oxidize the base metal component (A) in the floating alloy (A-M) nanoparticle, and to phase separate into the thus-oxidized base metal component (AxOy) and the noble metal component (M), to thereby obtain a composite nanoparticle (M-AxOy) having one noble metal particle (M) combined to the surface of a particulate base metal oxide (AxOy).
