Provided is apparatus for fabricating materials, including: a first mold including a first forming unit pressing a first material, and a second forming mold arranged at a bottom surface of the first forming unit to have an opening exposing the first material and to form at least a part of the first material by being meshed at a part with the first forming unit; a second mold arranged at a bottom surface of the first mold to support a second material; and an interlocking mold including a fixing unit interposed between the first and second molds to fix the second material arranged at the second mold by pressing the second material, and an interlocking unit ascendably and descendibly coupled to the fixing unit to form the second material by pressing the second material in association with the forming of the first material.

In a plate-type optical member for a multi-panel display device in which a plurality of individual display devices are joined and which includes junction area in which non-active areas of the individual display devices are arranged, the plate-type optical member includes plural optical fibers that have input ends opened to the lower part of the plate-type optical member and output ends opened to the upper part of the plate-type optical member and a resin support that supports the optical fibers. It is possible to guarantee image continuity in panel junction areas by disposing the plate-type optical member on the front surface of the multi-panel display device.

Methods for making articles comprising crystalline material. Exemplary articles made by a method described herein include electronics enclosure (e.g., a watch case, cellular phone case, or a tablet case).

There are provided a lens forming mold, and a manufacturing method for a cylindrical lens, with which cylindrical lenses having good mass productivity can be manufactured. A lens forming mold for forming a molding on which a plurality of cylindrical surfaces are arranged in parallel includes: a first mold including a plurality of cylindrical surface forming portions that are arranged in parallel at equal intervals; and a first flat surface forming portion that is provided between adjacent cylindrical surface forming portions; and a second mold that sandwiches the glass material and faces the first mold when the molding is molded, in which the second mold includes a second flat surface forming portion that faces the plurality of cylindrical surface forming portions and the first flat surface forming portion.

Provided is a method that can manufacture a glass plate having a curved surface shape with high surface accuracy even without polishing the surface after forming and a glass plate manufactured by the method. The method of manufacturing a glass plate having a curved surface shape includes the steps of: preparing an original glass plate, a forming die (10) including a recess (11) corresponding to the curved surface shape, and a forming tool (20) operable to press the original glass plate (2); placing the original glass plate (2) on the recess (11) in the forming die (10); heating the original glass plate (2) and the forming die (10); maintaining a temperature of a surface of the recess (11) in the forming die at a temperature lower than a temperature of the original glass plate (2); and giving the original glass plate (2) the curved surface shape by pressing the heated original glass plate (2) with the forming tool (20) to deform the original glass plate (2) while bringing the original glass plate (2) into contact with the surface of the recess (11).

The present disclosure relates to a method for manufacturing a hollow glass item and, specifically, to a method for manufacturing an item made of hollow pressed glass. The method includes a step of depositing at least one drop of molten glass into a mold intended for modelling a predetermined outer shape of the glass item to be manufactured; a step of pressing the molten glass into the mold by a shaping punch in order to shape the hollow glass item by hollowing out an inside space; a step of marking the glass item with a marking tool which is independent from the shaping punch, in order to imprint at least one raised and/or recessed pattern in the inside space of the glass item; a step of cooling the marked, pressed glass item; and a step of removing the glass item from the mold.

A device for manufacturing SiO.sub.2TiO.sub.2 based glass by growing a glass ingot upon a target by a direct method. The device includes the target, comprising a thermal storage portion that accumulates heat by being preheated, and a heat insulating portion that suppresses conduction of heat from the thermal storage portion in a direction opposite to the glass ingot.

The present disclosure provides an improved production method for optical elements. In this case, it is desirable to achieve high contour accuracy and/or surface quality for optical elements or lenses or headlight lens. In addition, it is desirable to reduce the costs of a production process for objective lenses and/or headlights, microprojectors or vehicle headlights.
