Abstract: A medical instrument effectively suppresses a situation in which the edge of a blade springs immediately after completion of incision, excision, or the like.

Abstract: It is a subject of the present invention to provide eyeglasses which can be easily put on and off with one hand and which are capable of preventing shifts of the eyeglasses when worn. The present invention relates to eyeglasses 100 comprising a pair of right and left lenses R, a front frame portion 1 supporting the lenses R, a pad portion 2 mounted to a center of the front frame portion 1, a temple portion 5 extending rearward from an end portion on one side of the front frame portion 1 and an abutting portion 10 formed at an end portion on the other side of the front frame portion 1, wherein the temple portion 5 is hooked to an ear while the abutting portion 10 is in a state in which it abuts a side surface of a face.

Abstract: The present invention provides a temple that has a sufficient elasticity and that can respond to twisting so as not to apply excessive force to a hinge portion or a bracket on the side of a lens portion, when a pair of eyeglasses is worn, and a pair of eyeglasses provided with the temple. In a temple (A) for a pair of eyeglasses including an elastic compression portion between a hinge portion (3) to a lens portion and an ear pad portion (2), the elastic compression portion (1) is provided with a plurality of linear arch portions (11) and the linear arch portions are arranged side by side.

Abstract: Disclosed are: a structural member for use in an eyeglass which has a super elastic property and shape memory property while retaining an excellent biocompatibility in addition to the fact that it is N-free, and which also has an excellent cold workability; an eyeglass frame containing the structural member; and a process for producing the structural member or eyeglass frame. A structural member for an eyeglass containing a Ti—Nb—Zr alloy which comprises (A) 40 to 75% by weight of Ti, (B) 18 to 30% by weight of Nb, (C) 10 to 30% by weight of Zr and (D) 0.2 to 3.7% by weight of at least one additive metal element selected from the group consisting of Al, In and Ga.

Abstract: A revolving structure for a glasses part for revolving a second member relative to a first member is provided with a rotational shaft provided on the first member and a cylindrical member with elasticity which is fitted on the rotational shaft externally, where the cylindrical member is fitted on the second member in a state that the cylindrical member is pressed by a pressing member and is not rotated, even if the rotational shaft of the first member is rotated. The second member has a groove portion a in which the cylindrical member is fitted and an arc face for contact with a circumferential face of the cylindrical member is formed on the groove portion. Accordingly, a revolving structure for a glasses part where when a rotational shaft is rotated, sufficient frictional resistant force is provided and entrance of dust or the like is prevented.

Abstract: A turning mechanism of a temple with respect to a bracket capable of always keeping the resistance force relative to the turning of the temple T with respect to the bracket and of regulating the resistance force. The turning mechanism comprises a shaft supporting portion provided on the bracket and having a hollow hole section therein, a shaft portion provided on the temple and having a hollow hole section therein, and an expansion member, wherein the expansion member is press-fitted in the hollow hole section of the shaft portion in a state where the shaft portion is fitted in the shaft supporting portion to produce a friction force due to a pressing force of the expansion member, thereby applying a resistance force against the turning of the temple.
