Title: Intraocular lens
Inventor: FUJINO TOKUYA
IPC: A61L27/00
Filed: 1998-12-02
Abstract: PROBLEM TO BE SOLVED: To provide an foldable intraocular lens with good resolution in an esterification treatment method by heating an intraocular lens base material using a composition containing monomer having a carboxyl group until an internal recess disappears, and then by softening the base material by esterification treatment. SOLUTION: In manufacturing an intraocular lens at first an intraocular lens base material using a composition containing monomer having a carboxyl group is heated until an internal recess disappears. Next, heat generated in the base material by heat-treatment is gradually cooled. Subsequently, the base material is fixed to a cutting jig for an in-eye lens in a method that does not cause any recess in the base material. After the base material is cut in the in-eye lens shape, this base material is esterificated and softened. At this time, the base material is the composition containing monomer represented by a formula (where, R1 is hydrogen or an alkyl group until carbon number 1-6, R2 is hydrogen or an alkyl group until carbon number 1-6, and R3 is hydrogen or an methyl group).

Title: Jumping of needle rod and device therefor
Inventor: TAJIMA IKUO
IPC: D05B55/16
Filed: 1989-12-29
Abstract: PURPOSE:To reduce the generation of noise in jumping by transmitting the movement of the first lever to the second lever for jumping when receiving a jumping signal and turning a needle rod driving member to a jumping position by the movement of the second lever. CONSTITUTION:When a solenoid 73 is turned ON by a jumping signal supplied from a control system, the top edge of a plunger 75b projects from the edge surface of a supporting cylinder 77, and the first lever 80 and the second lever 82 turn, having the supporting cylinder 77 as fulcrum. In this case, the pressing surface 45 of a needle rod driving member 42 is pressed by the roller 83 of the lever 82, and the driving member 42 turns in the direction of arrow, and the engaging projection pieces 43 and 44 are released from the projection pin 22 of a needle rod embracing member 20. Accordingly, the transmission of the rising/lowering operation from the driving member 42 to the needle rod 18 is cut off, and a jumping state is generated. As for the needle rod 18, since the projection pin 22 is restrained by the engaging projection pieces 43 and 44 to the top dead center, a top dead center stopper 26 is struck to the undersurface of the lateral frame 14a of the needle rod case 14, and the generation of noise can be obviated.
