Abstract: PURPOSE:To obtain the optical transmission body having a continuous refractive index distribution from the central part to the outer peripheral part by diffusing a monomer C which has the refractive index lower than the refractive index of a monomer A after polymn. into a mixture composed of the monomer A and a polymer B from the outer peripheral part to form the concn. distribution of the monomer A and the monomer C, then polymerizing the monomers. CONSTITUTION:The mixture 1 composed of the monomer A and the polymer B is inserted into a cylinder 3 and is extruded from a combination nozzle 4 by a piston 2. The monomer C which has the refractive index lower than the refractive index of the monomer A after polymn. is diffused from a porous part 5 into the mixture to form the concn. distribution of the monomer A and the monomer C in the fiber. The monomers are thereafter polymerized in a part 7 for irradiation with active rays and the fiber is passed through nip rollers 9, by which the optical transmisison body is continuously obtd. The optical transmission body 10 having the refractive index distribution continuous from the central part to the outer peripheral part is obtd. in this way.

Abstract: PURPOSE:To enable stable cutting of tab leads by keeping the cutting stress of a tab lead hung on the sealing resin, by a method wherein tab leads are cut by feeding a punch from the lead frame surface side with which the die having a resin casting gate of the upper and lower dies comes into contact. CONSTITUTION:Resin sealing is carried out by using the lead frame. Next, in the case of cutting tab leads 2 after leads 1 are bent, the semiconductor device is turned upside-down so that the leads 1 turn upward: that is, so that the gate part comes to the upper half of the sealing resin 3. Then, a tab lead 2 is supported with the lower half of the sealing resin 3 and the lead frame outer support 4, and the tab lead 2 is cut by lowering the punch 09 from above. This results in the application of tab lead cutting stress to the sealing resin at the part of no gate parts and can avoid voids at the gate part; therefore, stable tab lead cutting is enabled. Besides, a similar effect can be obtained by supporting the semiconductor device with leads downward, and by raising the punch 9 from below.
