A flash lamp irradiation apparatus comprises at least one flash lamp having a bulb made of translucent material, two or more trigger members disposed along a tube axis of the at least one flash lamp, wherein voltage is simultaneously impressed to the two or more trigger members at lighting in order to emit light from the at least one flash lamp.

Flash lamp irradiation apparatus

In a light heating apparatus having a flash lamp in which noble gas is enclosed, a casing surrounding the flash lamp, a stage where a silicon wafer on which light from the flash lamp is emitted is placed, and a power feeding apparatus for controlling light emission of the flash lamp, B/A is greater than 1.0 wherein integrated radiant intensity in a range from 220 to 370 nm wavelength is represented as A and integrated radiant intensity in a range from 370 to 800 nm wavelength.

Light heating apparatus and method therefor

The object of the invention to devise an electrical insertion body for a tube lamp in which sealing bodies of an electrically conductive inorganic material component and a dielectric inorganic material component and upholding parts of the electrodes are attached securely to one another by sintering, and in which neither leaks nor falling out of the upholding parts of the electrodes occur. The object is achieved as claimed in the invention, in an electrical insertion body for a tube lamp in which an upholding part of the electrode is inserted into the center opening of a respective sealing body of a functional gradient material for a tube lamp, in that in the boundary areas between the sealing bodies and the upholding parts of the electrodes one diffusion area at a time is formed, in which the electrically conductive inorganic material component of the sealing body, the metallic component of the upholding part of the electrode and a diffusion accelerator are present diffused into one another, which at the sintering temperature accelerates diffusion of the electrically conductive inorganic material component of the sealing body and of the metallic component of the upholding part of the electrode and that in this way the upholding part of the electrode and the electrically conductive inorganic material component of the sealing body are joined to one another.

Electricity lead-in body for bulb and method for manufacturing the same

An electricity introducing member for a tube lamp includes a closing member and an electrode upholding part formed integrally together; the closing member includes a plurality of layers each comprising a conductive component and silica, the volumetric proportion of the silica being n,, n,n,nx such that n,>n,n,nx, are successively laminated in the form of a cylinder, so that the closing member serves as a functional gradient material; where the diameter of the closing member is D in mm and the total thickness of the laminate of the layers each containing more than 80 volume % of silica is L in mm; L/D is not less than 2: the electrode upholding part is shrink-fitted from the surface on the side of the layer n,up to the layer containing at most 80 volume % of silica in the closing member. Preferably, where the diameter of the electrode upholding part is d in mm, the ratio of d/D is from 0.12 to 0.6.
