Light condensing device, photovoltaic device, light condensing sheet, photovoltaic sheet, and method for manufacturing light condensing device or photovoltaic device

To provide a photovoltaic device and a light condensing device having a high condensing rate which can be manufactured easily and at low cost. This light condensing device is provided with: a light-guiding subtract for causing light to propagate between a rear-side surface and a front-side surface for receiving light from a light source; a reflective layer for light guiding, in which a reflection-type hologram is formed for reflecting light incident at a first incidence angle less than the critical angle of the light-guiding substrate at a reflection angle greater than the critical angle, the reflective layer being provided to the rear-side surface; and an emission window for causing light incident at a second incidence angle equal to or greater than the critical angle to be emitted from the light-guiding substrate, the emission window being provided to the front-side surface and/or the rear-side surface.. ...

Tubular fabric, method of knitting tubular fabric, and sock

A bent part of a sock has (i) a bulging part having a first bulging region which includes a region in which the number of wales decreases, and a second bulging region which includes a region in which the number of wales increases and (ii) an extended part having a first extended region in which the number of wales increases, and a second extended region in which the number of wales decreases. The extended part is located so as to be closer to a bend direction side than the bulging part. ... Okamoto Corporation

Composition for optical stereolithography and method for producing stereolithographic object using the same

Provided is a water-soluble composition for optical three-dimensional modeling having little burden on the environment, which enables the production of a three-dimensional model that has both little warping deformation and excellent mechanical characteristics, while exhibiting good adhesion between cured film layers during the production process of the three-dimensional model; and a method for producing a three-dimensional model, which uses this composition for optical three-dimensional modeling. Specifically provided is a water-soluble composition for optical three-dimensional modeling, which contains (a) 10-70% by mass of a water-soluble cationically polymerizable compound that is an ether derivative compound of a sorbitol having a glycidyl ether structure, (b) 1-30% by mass of a water-soluble radically polymerizable compound having a methacryl group and/or an acryl group, (c) 0.1-20% by mass of an antimony-free cationic polymerization initiator that is a sulfonium compound or a bis(alkylphenyl)iodonium compound, and (d) 0.1-20% by mass of a radical polymerization initiator.. ...

Pressure-resistant glass sphere

In a pressure-resistant glass sphere used for exploration of deep sea, ocean floor or the like, it is an important issue to reduce weight and increase a floating force while keeping pressure resistance capable of withstanding high water pressure of deep sea or the like and being used repeatedly. A pressure-resistant glass sphere of the present invention is composed of a pair of glass-made hollow hemispherical bodies, wherein the glass-made hollow hemispherical bodies are joined with each other at ground joint surfaces located on an equatorial plane of the pressure-resistant glass sphere so that the ground joint surfaces serve as a joining surface, and characterized in that a thickness of a spherical shell of the glass-made hollow hemispherical bodies is thicker at an equatorial plane portion than the portion other than the equatorial plane portion having a predetermined width from the ground joint surfaces.. ...
