  • Patent number: 8979104
    Abstract: A structure (10) for a front section of a vehicle body in a vehicle body (1) comprising a front chamber (3) disposed on the forward side of a vehicle interior (2) is provided with the following: a pair of front side members (11), located within the front chamber, that extend in the longitudinal direction of the vehicle body; a pair of strut towers (16) disposed on either side in the width direction of the front chamber and within which front wheel suspensions are disposed; and reinforcement members (20) that link the top of each strut tower with the front side members that face the strut towers, and that extend between the strut towers and the front side members. This configuration allows a structure for a front section of a vehicle body to be provided that can efficiently improve the rigidity of the vehicle body of an automobile against torsion and against lateral bending, and that can efficiently reduce the weight of the vehicle body by means of thickness reduction using a high-strength steel plate.

  • Patent number: 6801822
    Abstract: In the production management system, supervisors of manufacturing and production check section, component check section, and manufacturing technical section set retrieval conditions for retrieving data stored in a database of a step-monitoring server in order to obtain information on daily, hourly and monthly statuses of products in the production management system by using output system clients. The input retrieval conditions are transmitted to the step-monitoring server. Data matching with these retrieval conditions are retrieved from the database of the step-monitoring server. The retrieved data is chronologically processed and displayed on screens of the clients which requested the data.

  • Patent number: 5879765
    Abstract: This invention provides a thin metallic sheet structure having excellent sound damping characteristics which can lower the sound pressure level of a sound inherent to a thin metallic sheet structure when this structure is patted, and can quickly damp the sound by a simple structure. In a flat sheet-like or box-like structure comprising a thin metallic external sheet and beams for reinforcing the external sheet, a thin metallic sheet structure having excellent sound damping characteristics according to the present invention employs the construction wherein the reinforcing beams 2 are brought into contact with one of the surfaces of the thin metallic external sheet 1 through a sound damping sheet 3, and the coupling state between the sound damping sheet 3 and the thin metallic external plate 1 or the reinforcing beams 2 is a non-coupling state or a discrete coupling state on at least one of the surfaces of the sound damping sheet 3.
