Abstract: The present invention relates to a piercing apparatus and a piercing method which drive a punch. The piercing apparatus includes a local heating device for heating part of the workpiece in a temperature range less than a melting point of the workpiece and a punch driving device for driving the punch toward the part of the workpiece which was heated by the local heating device. The piercing method includes a local heating step for heating part of the workpiece in a temperature range less than a melting point of the workpiece and a stamping step for driving the punch toward the part of the workpiece which was heated in the local heating step.

Abstract: A punching apparatus includes a holding part for holding a workpiece, a punch having a punching portion at an axial end thereof, the punching portion being configured to be inserted into the workpiece for punching the workpiece. The punching apparatus further includes a guide part supporting the punch so as to be movable in an axial direction of the punch, and a rotating part for rotating the punch around the axial direction of the punch while the punch is away from the workpiece.

Abstract: In one aspect, the disclosure features an article, including a fiber waveguide extending along a waveguide axis, the fiber waveguide including a core extending along the waveguide axis and a confinement region surrounding the core. The confinement region is configured to guide radiation at a first wavelength, ?1, along the waveguide axis and is configured to transmit at least some of the radiation at a second wavelength, ?2, incident on the confinement region along a path, where ?1 and ?2 are different. The core includes a core material selected to interact with radiation at ?1 to produce radiation at ?2.

Abstract: Disclosed herein is a camera lens comprising a thermoplastic composition comprising a poly(aliphatic ester)-polycarbonate copolymer comprising soft block ester units derived from an alpha, omega C6-20 aliphatic dicarboxylic acid or derivative thereof, a dihydroxyaromatic compound, and a carbonate source, wherein the thermoplastic composition has a melt volume rate of 13 to 25 cc/10 min at 250° C. and under a load of 1.2 Kg and a dwell time of 6 minutes, according to ASTM D1238-04, and wherein the camera lens has an effective lens area of 0.5 to 100 mm2. A method of making the camera lens, and a camera lens comprising a thermoplastic composition comprising a redistribution product of a poly(aliphatic ester)-polycarbonate, are also disclosed.
