  • OPTICAL FILM TRANSPORT METHOD, AND APPARATUS USING THE SAME
    Publication number: 20140041497
    Abstract: In a process of transporting a strip-shaped optical film F, the optical film F is cut to a predetermined length. Thereafter, the sheet-like optical films F divided by the cutting are intermittently transported while the strip-shaped optical film F is fed by the predetermined length such that a portion to be cut next reaches a cutting action position. Further, a leading one of the sheet-like optical films F in the intermittent transport process is transported to a continuous transport process such that a rear end thereof passes the intermittent transport process in a subsequent intermittent transport operation. Herein, the sheet-like optical film F is transported to the downstream-side continuous transport process following the intermittent transport process to continuously transport the optical film F.

  • Disk brake device
    Patent number: 8573370
    Abstract: A cam housing assembly oscillates in association with rotation of an eccentric cam which is attached to a camshaft and is allowed to press a clutch by cam pins of the cam housing assembly. A pair of piston assemblies are provided of which each includes a piston which can slide within a sleeve, a spindle and a nut which screws on to the spindle and are supported in hole portions in a caliper body so as to oscillate therein, whereby a brake pad is pressed against by a plug after the spindle, the nut and the piston are sequentially pressed by pressing a clutch by the cam pins. Since the spindle and the nut are screwed on to each other through a reversible screw, a gap is adjusted automatically as the pad wears.

  • Optical film cutting method and apparatus using the same
    Patent number: 8524536
    Abstract: Nip rollers 11 and 12 each including a pair of upper and lower rollers are disposed on an upstream side and a downstream side with a portion to be cut of an optical film F located therebetween. In the nip roller 12, a center axis C of the upper roller 12b is displaced relative to a center axis L of the drive roller 12a in a direction away from the portion to be cut. Upon cutting of the polarizing film F, the upper rollers 11b and 12b are simultaneously moved downward, so that a timing at which the downstream nip roller 12 nips the polarizing film F is delayed. Further, the nip roller 12 pulls the polarizing film F in the direction away from the portion to be cut, so that tension is applied to the polarizing film F. In this state, the polarizing film F is cut by a laser device 10.
