The present invention relates to a process for comminuting glass fibers from waste glass-based fibrous materials.

A multicore fiber includes a plurality of unit multicore fibers each including: a plurality of core portions; and a clad portion which is formed in an outer circumference of the core portions and has a refractive index lower than a maximum refractive index of the core portions. The plurality of the core portions have substantially same refractive index profile and different group delays at same wavelength in same propagation mode. The core portions of the multicore fiber are configured so that the core portions of the plurality of the unit multicore fibers are connected in cascade, a maximum value of differential group delays between the core portions of the multicore fiber is smaller than a reduced value of a maximum value of differential group delays between the core portions of each unit multicore fiber as a value in terms of a length of the multicore fiber.

A portable computing device includes a processor, a memory, and a portable computing device case that encloses one or more integrated circuits, including at least the processor and the memory. The case includes a molded fiber-reinforced polymer (FRP) material that includes a polymer material and elongated fibers that adhere to the polymer material and that have a property that varies over a length of the fibers along an elongation axis of the fibers, wherein an adhesion strength between the fibers and the polymer is determined at least in part by a property of the fibers that varies over a length of the fibers along the elongation axis.

A vacuum heat insulator includes a core member that is a stack of fibrous sheets and a cover member enclosing the core member. Each of the fibrous sheets includes curved chopped fibers and curved fibers.

A method of making an alkali glass powder includes obtaining down chute waste fiberglass (DCWF) and post-consumer waste glass (PCWG), processing the DCWF into a DCWF particulate form, combining the DCWF and PCWG at a ratio of PCWG to DCWF, and co-grinding the combined DCWF particulate form and the PCWG into a DCWF-PCWG powder having an alkali content based on the ratio of PCWG to DCWF.
