A composition for manufacture of a light emitting particle-polymer composite, the composition including a light emitting particle, a first monomer including at least two thiol groups, each located at a terminal end of the first monomer, and a second monomer including at least two unsaturated carbon-carbon bonds, each located at a terminal end of the second monomer. The ratio of the inner diameter \u03a6dA before plastic deformation in the plastic deformation portion of the outer joint member and the inner diameter \u03a6dB after the plastic deformation is set in the range from 1. The forwarding implementation forwards its invocation to the implementation of that the virtual function in the implementing class. The negative electrode active material layer has a second region neighboring a surface thereof, and the second region contains artificial graphite in a weight ratio of equal to or greater than 80% of the graphite material. For a next instance of the method detected by the runtime machine, the runtime machine accesses the cached separate result of the method in lieu of executing the method again. When the cover is in its closed position, a retention force is provided by the strut system and is distributed about the cover.
