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 system, method and software arrangement are provided for generating press-formed parts having a more consistent quality based on improved determination of processing conditions. For example, an apparatus can be configured to compare actual performance values of material properties provided by a material property database with standard values, and to adjust forming conditions such as a forming speed and a blank-holder pressure in accordance with the compared result. A control arrangement can be provided to control a press-forming device using the adjusted forming conditions. Accordingly, it may be possible to reduce occurrences of defects such as cracks and wrinkles when press-forming materials, and to obtain products having consistent quality and substantially identical shapes.

摘要： A front vehicle body structure for a vehicle body (1) having a vehicle interior compartment (2) and a front compartment (3) which is provided in front of the vehicle interior compartment (2). The front vehicle body structure is provided with: strut towers (16) to which the upper edges of struts for the front wheels are mounted; front pillars (20) extending, at positions at the front of the vehicle interior compartment and on both sides in the width direction, from the roof of the vehicle interior compartment toward the upper edge of the rear of the front compartment; and reinforcement members (25, 70) each having one end joined to the strut tower and the other end joined to the front pillar. Each of the reinforcement members is joined to the strut tower on both the inner side and outer side of a plane (S) with respect to the vehicle body, the plane (S) passing through the axis of the strut and extending in the front-rear direction of the vehicle body. As a result of the configuration, the front vehicle body structure can efficiently increase the torsional rigidity of the vehicle body of the automobile and in turn can efficiently reduce the weight of the vehicle body by a plate thickness reduction achieved using a high-tensile steel plate.
