摘要:
The present invention is a floor panel structure of a car body that can reduce noise within the automobile cabin. The present invention is a car body floor panel structure wherein the floor of an automobile has a floor panel S1, S2, S5 or S6 connected to car body frame members 12, 14, 16, 18, 20, 22, 24 and/or 26, and also a predetermined mode of vibration is generated to suppress the generation of acoustic emission from the floor panel. The floor panel vibration mode adjusting structure has rectangular rigidity adjusting areas 62 that are formed by causing the floor panel to protrude upward or downward in order to generate 2×1 mode or 2×2 mode vibration in the floor panel in a frequency band that nearly matches the tire cavity resonance frequency.

An on-vehicle information provision apparatus is provided that visually provides a vehicle occupant with positional information on an object. The apparatus includes object setting device that sets the object, visibility determination device that determining whether or not the occupant can see the object and positional information display device that, when it is determined that the occupants can see the object, visually informs the occupant of an apparent position of the object within an actual landscape that is being seen by the occupant by displaying image information showing the object superimposed on the landscape.

A hollow cylindrical pulley body 5 is carried rotatably by a hollow cylindrical shaft member 11 . A support rod 8 is inserted in the shaft member 11 to support the shaft member 11 for rocking motion about a pivot axis C2 orthogonal to the shaft member 11. The pivot axis C2 is inclined backward in the direction of belt travel with respect to the direction of load on the shaft member 11. With this configuration, when the drive belt 3 deviates to one side, the pulley body 5 is immediately angularly moved so that it is inclined with a level difference with respect to the direction of load on the shaft member 11 and is positioned obliquely relative to the drive belt 3 , thereby producing a force of returning the drive belt 3 to its normal position.

The present invention is a floor panel (2) structure of a car body where an automobile floor includes a floor panel that is connected to the frame members (12,14,20,22) of the car body and also have a vibration mode adjusting structure that suppresses the generation of acoustic emission by generating 2×1 mode vibrations in a predetermined frequency band. The floor panel has a non-rectangular vibration region and the vibration mode adjusting structure of the floor panel has a vibration adjusting part that defines the position of node of 2×1 mode vibration, and this vibration adjusting part is disposed within the non-rectangular vibration region so as not to touch the frame members and so as to form two regions where the vibration volumes of two antinodes of vibration in 2×1 mode are made nearly the same.

The present invention relates to a method for making bone particles from bone of a variety of sizes and a workpiece forming and holding device for use with the method. The workpiece forming device includes a base and a base frame attached to the surface of the base. An apparatus for forming a solidified mass of bone and immobilization medium is also provided which includes the workpiece forming device and a detachable former member enclosing the base frame. Bone is immersed in an immobilization medium within such workpiece forming device, which is solidified to form a solidified mass of bone and immobilization medium and then subdivided to provide particles of bone in association to with immobilization medium. The immobilization medium may be optionally removed to leave bone particles suitable for use in orthopedic applications including implants.

A polarization-maintaining photonic crystal fiber 10 includes six thin holes 4a and 4b adjacent to a core 1 . Among these holes 4a and 4b , a pair of holes 4b at opposite sides of the core 1 have a diameter greater than that of the other four thin holes 4a , and therefore, the polarization-maintaining photonic crystal fiber 10 has polarization-maintaining ability. An overclad layer 3 exists around the clad layer 2 which includes a large number of thin holes 4a and 4b around the core 1 . The overclad layer 3 includes a pair of marking portions 5 at opposite sides of the core 1 . The marking portions 5 are holes which can be seen at positions different from the clad layer 2 when the fiber 10 is viewed from a position right above the fiber 10 in the drawing. In this way, the direction of the polarization plane of the polarization-maintaining photonic crystal fiber 10 is identified.
