Abstract: Provided are a method of full body cutting a brittle material without via the bend-breaking step, an apparatus of cutting a brittle material, a method of manufacturing a brittle material, and a cut brittle material. A method of cutting a brittle material, the method comprising: a conveyance cutting step of converging and irradiating an infrared ray to the brittle material linearly along a line using an infrared line heater while moving the infrared line heater relative to the brittle material in a direction along the line, thereby cutting the brittle material along the line.

Abstract: A search extend setting unit that identifies a layer made to correspond to an asset specified by referencing a first database for recording assets made to correspond to each of users by relating each of the assets to a first layer that is a layer related to a virtual system individually used by each of the users, or to a second layer that is a layer related to hardware and software, and to set an extent for extracting information about other assets having a relationship with the specified asset according to a layer of the specified asset, and an extracting unit that extract other assets that have a relationship with the specified asset and are present in the extent set by referencing the first database and a second database for recording information indicating a relationship among the assets, and the first database based on the first asset.

Abstract: The invention relates to a method for putting color to glass. This method includes the steps of (a) introducing a laser beam into an interferometer such that the laser beam is split into at least first and second laser beams in the interferometer and that the at least first and second laser beams come out of the interferometer; and (b) irradiating a glass with the at least first and second laser beams to write a plurality of lines simultaneously on a surface of the glass and/or in an inside of the glass.

Abstract: The invention relates to a method for putting color to glass by irradiating a silicate glass, containing a non-bridging oxygen in its structure, with a laser light, thereby forming a non-bridging oxygen hole center therein to put a color to the glass. The invention further relates to a method for putting color to glass by irradiating a silver-ion-containing glass with a high-energy light, thereby forming silver particles in the glass through aggregation of silver ions to put a color to the glass. The invention further relates to a method for erasing color from colored glass by irradiating a colored portion of a glass with a laser light to selectively heat the colored portion by using a laser irradiation apparatus comprising (a) a laser oscillator, (b) a light modulator, (c) a condenser lens mounted on a linear translator, (d) an objective lens, and (e) a galvanometer mirror.

Abstract: The invention relates to a head-up display system including a transparent plate; a liquid crystal display for generating a display light of information; and a laminate of first and second &lgr;/4 films. This laminate is placed on a display panel of the liquid crystal display such that the display light is changed into S-polarized light or P-polarized light and that the S-polarized light or the P-polarized light is incident on the transparent plate. The laminate of first and second &lgr;/4 films may be replaced with a single &lgr;/2 film.
