The invention involves a childproof jar that suitable for medicinal items such as tablets, medication or other consumables that may be desirably restricted from children. The childproof mechanism that restricts access to the contents of the jar may employ a childproof cap comprising an outer cap and an inner cap that is operable by applying a force along the rotational axis of the capor by pressing down on the cap and twisting or rotating the cap. Typically, the jar is treated or coated with a uv-treatment or coating that limits or prevents light from reaching the contents of the jar.

Borosilicate glasses are disclosed having (in weight %) 66-76% SiO.sub.2, 0-8% Al.sub.2O.sub.3, 10-18% B.sub.2O.sub.3, 0-4% Li.sub.2O, 0-12% Na.sub.2O, 0-12% K.sub.2O, 1-1.5% Ag, 1.5-2.5% Cl.sup. and 0.01-0.06% of a summed amount of CuO and NiO, wherein the glass composition is bleachable upon exposure to ultraviolet irradiation from a stable state color or shade to a lighter color or shade. Such reverse photochromic borosilicate glass compositions may be thermally darkenable. The borosilicate glasses may be strengthened via ion-exchange strengthening treatment. The borosilicate glasses may retain their reverse photochromic and thermally darkenable properties even after ion-exchange strengthening treatment.

A sensitized, photo-structurable glasses and methods for producing are provided. The glasses includes Si.sup.4+, one or more crystal-agonist, one or more crystal-antagonist, and one or more pair of nucleating agents. The glasses are sensitized in that the glass reacts more sensitive to irradiation with UV-light and can be crystallized easier and with higher aspect ratios than a non-sensitized glass with equal composition. Furthermore, the sensitized glasses of this invention have smaller crystal sizes after irradiation and tempering than a non-sensitized glass with equal composition. The invention also relates to a structured glass product. Such product can be obtained by submitting the crystallized glass product to a subsequent etching step. The structured product can be used in components or as component for the application fields micro-technology, micro-reaction-technology, electronic packaging, micro-fluidics, FED spacer, bio-technology, interposer, and/or three-dimensional structured antennae.

A synthetic quartz glass substrate having a controlled hydrogen molecule concentration is prepared by (a) hot shaping a synthetic quartz glass ingot into a glass block, (b) slicing the glass block into a glass plate, (c) annealing the glass plate at 500-1,250 C. for 15-60 hours, (d) hydrogen doping treatment of the glass plate in a hydrogen gas atmosphere at 300-450 C. for 20-40 hours, and (e) dehydrogenation treatment of the glass plate at 200-400 C. for 5-10 hours.

A glass lining that has an excellent balance between a hydrophilic property and a hydrophobic property on its surface, that has less adhesion of dirt than a typical GL since having an excellent stain-proof property against both oily stains and aqueous stains, and that can maintain the stain-proof property and the self-cleaning performance for a long time after the glass lining is cleaned, leading to excellent cleaning performance and low dirt-adhesion. The glass lining includes a lining and a conductive inorganic compound contained in the lining. The glass lining is structured to have a plurality of hydrophilic concave portions and net-like hydrophobic convex portions connecting peripheries of the plurality of hydrophilic concave portions.

Methods for machining glass structures may be performed on fusion-drawn glass laminates having a core layer interposed between a first cladding layer and a second cladding layer. The core layer may be formed from a core glass composition having a core photosensitivity, the first cladding layer may be formed from a glass composition having a photosensitivity different from the core photosensitivity, and the second cladding layer may be formed from a glass composition having a photosensitivity different from the core photosensitivity. At least one of the core layer, the first cladding layer, and the second cladding layer is a photomachinable layer. The methods may include exposing a selected region of a photomachinable layer in the fusion-drawn laminate to ultraviolet radiation; heating the glass structure until the selected region crystallizes; and removing the crystallized material selectively from the photomachinable layer.

There is provided a production method of a resin composite module for a vehicle, which includes a resin module substrate, and a silicone-based polymer hard coat which is formed on the resin module substrate. The method includes forming the hard coat by coating a silicone-based polymer onto the resin module substrate, and radiating an ultraviolet ray onto at least a part of a surface of the hard coat such that a hardness thereof becomes 0.8 GPa or more as evaluated by a nanoindentation method. The radiating the ultraviolet ray uses a light source unit which includes a light source and emits an ultraviolet ray having a wavelength of 360 0nm or less from an emission surface thereof and radiates the ultraviolet ray onto the surface of the hard coat while a distance from the emission surface to the surface of the hard coat is 10 mm or less.
