摘要:
Disclosed is a manufacturing method for a fine powder exhibiting improved solubility, little impurity contamination, and a high recovery rate. Material to be ground and a grinding medium are suspended and stirred in a liquefied inert gas dispersion medium such as dried ice, and the material to be ground is made into a sub-micron or nano-sized fine powder. A uniform fine powder can be obtained when the material to be ground is a mixture having two or more components. Impurity contamination can be reduced by using granular dry ice as the grinding medium.

摘要:
A vehicle front structure reinforces a portion around a bumper to prevent local stress concentration. The vehicle front structure includes a first reinforcement (4) attached to the central part in the vehicle width direction of a bumper member (2), and includes second reinforcements (11) attached to the vehicle inside parts of corner parts (10) each defined by a side member (3) and the bumper member (2). The first reinforcement (4) is arranged so as to cover an upper part (2b) and a lower part (2c) of the bumper member (2). A side end part (4b) in the vehicle width direction of the first reinforcement (4), which is arranged in the upper part (2b) and the lower part (2c), is formed so as to extend to the outside in the vehicle width direction toward the rear of the vehicle. The second reinforcement (11) is formed into a triangular shape corresponding to the corner part (10), and has a side part (11a) tilting to the outside in the vehicle width direction toward the rear of vehicle so as to connect the side member (3) and the bumper member (2) with each other. The side end part (4d) of the first reinforcement (4) and the side part (11a) of the second reinforcement (11) are arranged on the same straight line.

An automobile bumper structure reduces damage to a vehicle body in an offset collision by having a bumper member in an offset collision area formed by a separate member.
