The sheet-like rubber forming device has a die body which has an opening having a predetermined cross sectional shape, and a variable die lip which is arranged in a front side of the die body and can change the height of the opening. The variable die lip is constructed by a first movable body and a second movable body. The die lip control unit controls the variable die lip so as to drive the first movable body in an opening direction from a state in which the first movable body and the second movable body are closed when the forming is started, hold the positions of the first movable body and the second movable body after reaching a predetermined height, and drive the second movable body in a closing direction when the forming is finished.

Device and method for forming sheet-like rubber

A method for forming a cylindrical rubber member includes bringing a dieclose to a forming drum, forming a winding start portion Sby extruding a rubber S and simultaneously starting to rotate the forming drumto gradually increase an extruding amount to an amount Qand gradually increase a distance between the dieand the forming drumto a distance Dcorresponding to a desired thickness of the cylindrical rubber member, winding the rubber S by maintaining the extruding amount at the amount Q, and maintaining the distance between the dieand the forming drumat the distance D, and forming a winding end portion Son the winding start portion Sby maintaining the distance between the dieand the forming drumat the distance Dand gradually reducing the extruding amount from the amount Q

The present invention provides an image pickup lens with a large focal depth from the center to the outer part of an image plane formed on an image sensor and capable of maintaining its focal depth within a practical range and thus suppressing a decline in the resolution. An image pickup lensincludes, in order from the object side to the image plane side, an aperture stop, a first lensthat is a biconvex lens having positive power, a second lensthat is a meniscus lens having negative power and whose lens surface facing the object side is convex, a third lensthat is a meniscus lens having positive power and whose lens surface facing the object side is concave, and a fourth lensthat is a biconcave lens having negative power. The image pickup lensincludes a multifocal lens on the lens surface of the first lensfacing the object side. D and Ymax satisfy the following conditional expression ():0max&#x2266;0.1&#x2003;&#x2003;(1)where D is an absolute value of the distance between the multifocal lens surface and a surface of the aperture stop on the optical axis, and Ymax is the absolute value of the maximum image height on an image plane formed on the image sensor.
