A method for bonding components to each other according to this invention bonds, to a plate-shaped member or a shaft, an ultraviolet-curable adhesive cured by irradiation with ultraviolet rays and a wavelength conversion element which emits ultraviolet rays by irradiation with X-rays. The plate-shaped member is brought into contact with the shaft through a bonding layer formed by the ultraviolet-curable adhesive and the wavelength conversion element. The X-rays are transmitted through the plate-shaped member or the shaft to the bonding layer located between the plate-shaped member and the shaft to cure the ultraviolet-curable adhesive.

Flat optical elements including a multi-level metasurface stack having two or more metasurface levels. Each metasurface level includes an arrangement of nanostructures, or protrusions, of one or more optically transmissive materials. A metasurface level may further include another optically transmissive material between the nanostructures, achieving a desired index contrast. Another metasurface level including additional nanostructures may be over a planar surface of this additional transmissive material. Another optically transmissive material may be between the additional nanostructures. This architecture may be followed for any number of levels, (e.g., a bi-layer, tri-layer, etc.). Each metasurface within the multi-level metasurface structure may be tuned to a particular optical wavelength. Such a multi-level metasurface may have greater bandwidth and/or achieve higher optical efficiency for a given band than a single metasurface. Molding techniques may be employed in metasurface fabrication to reduce the starting material cost and fabrication cost.

In addition, the invention relates to a cosmetic method for anti-aging skin treatment wherein the method comprises the steps of: subcutaneously administering of an effective amount a of a dermal filler or Botulinum toxin to an area of skin, preferably the face and/or neck area, wherein the administering is performed by a syringe and a hypodermic needle or cannula of the invention.

An automatic-darkening filter 10, 10 that comprises a first polarizer 14, a second polarizer 18, a first liquid-crystal cell 16, and a sensor 64. The first polarizer 14 has a first polarization direction, and the second polarizer 18 has a second polarization direction. The liquid crystal cell 16 is disposed between the first and second polarizers 14, 18 and contains first and second optically-transparent, flexible, glass layers 40 and 42 with the liquid crystal layer 48 being located between these layers. The sensor 64 detects incident light and causes a signal to be sent, which causes molecular rotation within the liquid crystal layer. The inventive automatic-darkening filter is beneficial in that overall product weight can be reduced and the view field can be increased.
