Information is stored in an optical element in the form of a glass or plastic body embodied as spectacles lens, spectacles lens blank or spectacles lens semi-finished product. The information in the form of data is stored on or in the glass or plastic body by creating at least one marking with a marking system. The marking can be read by a reading apparatus. The marking system has an interface for reading information individualizing the optical element. The marking is created permanently by the marking system on or in the optical element at a definition point of a local body-specific coordinate system set by two points on or in the optical element. In this body coordinate system, the manufacturer specifies the position of the lens horizontal and/or the far and/or the near and/or the prism reference point.

An object is to provide a composite pre-bonding treatment method that stabilizes quality of a bonded part. The present disclosure provides a composite pre-bonding treatment method performed when bonding a composite material to a member. The method includes: (S2) attaching an absorber adapted to absorb a contaminant to a surface of a prepreg laminate that is a precursor of the composite material; (S3) covering the prepreg laminate with a packaging material from above the absorber; (S4) vacuuming the packaging material and heating the prepreg laminate at a temperature lower than a curing temperature of a prepreg; (S5) then removing the packaging material; (S6) peeling off the absorber; (S7) attaching, to a surface of the prepreg laminate with the absorber peeled off, a release member that does not transfer silicone or fluorine to a resin, and then (S9) curing the prepreg laminate to mold the composite material; and (S11) peeling off the release member from the composite material before bonding the member.

An embossing die is provided to an embossing apparatus. The embossing die is heated by a heating unit which is provided to the embossing apparatus. The embossing die includes a convex shaped mold portion. The mold portion corresponds to one concave portion formed on a front face of a base material. The mold portion is an aggregate of a plurality of protrusions which are divided by a slit. The slit is provided to an outer surface of the mold portion which contacts the front face of the base material. In the slit, a cutting direction corresponds to a height direction of the mold portion. The plurality of protrusions are adjacent to each other through the slit.

The present disclosure is directed to a film formulation that resulted in a substantially non-migratory cold seal release film with improved blocking resistance. Specifically, the multilayered biaxially oriented polypropylene film can include a core layer of polypropylene homopolymer; a first outer layer on one side of the core layer that can be suitable for sealing, printing, or coating; and a second outer layer on the opposite side of the core layer that is a blocking resistant layer comprising thermoplastic polymers which reduce blocking tendency.

A method of the invention produces a composite material conjugate in which a first composite material and a second composite material are adhered without using an adhesive, wherein a first prepreg laminate to which a release member is attached is cured to form the first composite material, the release member being made of a material that does not transfer silicone and fluorine to the first prepreg laminate, after detaching the release member from the first composite material, surface treatment that imparts polar functional groups to the surface of the first composite material to which the release member was bonded is carried out to activate the surface, a second prepreg laminate is placed directly on the activated surface of the first composite material, and the second prepreg laminate is cured to form a second composite material adhered to the first composite material.
