摘要:
A bamboo board 10 of the present invention is produced by preparing a plurality of square tubular bodies 12 fabricated by cutting a surface layer 11a of tubes that form bamboo rods 11 so that the cross sectional surfaces that are orthogonal to the longitudinal direction of the bamboo rods 11 have two groups of two parallel facing surfaces, aligning the plurality of square tubular bodies 12 parallel to one another, and gluing facing cut surfaces 12a of the plurality of square tubular bodies 12 in place by means of a first adhesive agent 21. The bamboo board is produced as a tube without splitting bamboo rods or cutting and shaping an arc-shaped bamboo material into a planar shape in a conventional method is a light-weight board having a sufficient strength, due to less deformation such as warping when using bamboo shaped into a planar configuration and use of a natural hollow structure of bamboo.

An apparatus for hot pressing boards comprises a conveying and setting mechanism for setting a board (120) put on a caul plate (200) in a predetermined hot pressing position, and a hot pressing mechanism including a hot plate and a spacer, the board being hot pressed in a closed space defined by the hot plate, the caul plate (200) and the spacer. The conveying and setting mechanism includes a conveying member (410) for supporting the caul plate (200) in a state free from frictional contact with any other member while the caul plate (200) is conveyed to a hot pressing section (310), and a setting member (440) for supporting the caul plate (210) in succession to the conveying member (410) and setting the caul plate (200) in the hot pressing position, the setting member (440) being retreated to a position free from interference with hot pressing operation after the setting of the caul plate (200) in the hot pressing position.

A male connecting device for medical use 1 includes a male connector 10 having a cylindrical configuration and a threadedly engageable cylinder 20 rotatably coupled to the male connector 10. A male luer portion 11 of the male connector 10 and a female luer portion 2a of the female connector 2 are joined by turning the threadedly engageable cylinder 20 in a tightening direction T. The male connecting device 1 further includes a loosening prevention mechanism 40 that prohibits rotation of the threadedly engageable cylinder 20 in a loosening direction L with respect to the male connector 10. The loosening prevention mechanism 40 includes ratchet teeth 41 formed in an inner periphery of the threadedly engageable cylinder 20, an elastic leaf 42 formed in the male connector 10 and extends in a circumferential direction and an engageable claw 43 protruded from a free end of the elastic leaf 42 and engageable with the ratchet teeth 41.

A connecting structure for medical use includes a first connecting portion 1 and a second connecting portion 2. The first connecting portion 1 includes a threadedly engageable portion 22a, a support portion 22b and a sealing portion 14. The second connecting portion 2 includes a threadedly engageable portion 2c and a sealing portion 2b. The threadedly engageable portions are threadedly engageable with each other. The sealing portions are joinable to each other by advancement of a threaded engagement between the threadedly engageable portions. An operating cylinder 30 is mounted on an outer periphery of the support portion 22b. A torque limiting mechanism 40 is disposed between the operating cylinder 30 and the support portion 22b. The sealing portions 14, 2b can be joined by turning the operating cylinder 30 in a threaded engagement advancing direction. When a rotary torque applied to the operating cylinder 30 reaches a predetermined torque as a result of a resistance generated by the joining of the sealing portions, the operating cylinder 30 is turned free from the support portion 22b. By this arrangement, appropriate sealing properties can be secured and the sealing portions can be prevented from breakages.

A connecting structure for medical use includes a male assembly 1 and a female connector 2. The male assembly 1 includes a male connector 10 and a threadedly engageable cylinder 20. A male luer portion 11 of the male connector 10 and a female luer portion 2a of the female connector 2 are joined by turning the threadedly engageable cylinder 20 in a tightening direction in a state where a female screw 21a of the threadedly engageable cylinder 20 and an engageable protrusion 2c of the female connector 2 are threadedly engaged with each other. A torque limiting mechanism 50 is disposed between an operation cylinder 30 mounted on an outer periphery of the threadedly engageable cylinder 20 and the threadedly engageable cylinder 20. Engageable teeth 51 are formed in an inner periphery of one end portion of the operation cylinder 30 over an entire periphery. A slit 54 is formed in one end portion of the threadedly engageable cylinder 20. The slit is composed only of a straight portion extending from an end of the threadedly engageable cylinder in an axial direction. An area adjacent to the slit 54 is provided as an elastically deformable portion 52. A first engageable claw 53 engageable with the engageable teeth 51 is formed in the elastically deformable portion 52.
