A resin composition, including an aromatic polycarbonate resin, wherein when colorimetry is performed by using a molded body for optical characteristic measurement formed of the resin composition, the molded body including an entering portion from which light enters, an emitting portion from which the entered light is emitted, and a light-guiding portion configured to guide the light that has entered from the entering portion to the emitting portion, and the light-guiding portion including an optical path having such a curvature that the entered light is totally reflected, and by using a white light-emitting diode as a light source, a difference (Y2−Y1) between a y(Y1) of the molded body for optical characteristic measurement in a CIE 1931 color system at a position of a light-guiding path distant from the entering portion by 125 mm.

The present disclosure includes thin, high-stiffness laminates, portable electronic device housings including the same, and methods for making such laminates and portable electronic device housings. Some laminates include an inner section having one or more first laminae and one or more second laminae, and first and second outer sections disposed on opposing sides of the inner section, each having one or more third laminae The laminate has a width and a length that is perpendicular to the width. Each of the first lamina(e) can have fibers aligned in a direction parallel to the length, each of the second lamina(e) can have fibers aligned in a direction parallel to the width, and each of the third lamina(e) can have fibers aligned in a direction angnlarly disposed at an angle of at least 10 degrees to each of the length and the width.

A cooling plate for an injection molding machine includes a plate body, a plurality of sockets in the plate body for receiving respective spigot portions of a plurality of cooling tubes, and a cooling fluid conduit system in the plate body for cooling the cooling tubes. The cooling plate further includes an air conduit system in the plate body for providing air flow communication with the cooling tubes. Each socket forms a blockable flow passage between the cooling fluid conduit system and the air conduit system.
