    Abstract: PROBLEM TO BE SOLVED: To obtain a system which is insensitive for a temp. change by sticking an optical member with a fused seal to a base body having almost zero or a negative coefft. of thermal expansion CTE to constitute an optical device and preparing the seal by adding and fusing a low melting point glass frit having a positive CTE and a glass ceramic material having a negative CTE in a mill. SOLUTION: A frit of low melting point glass having a positive coefft. of thermal expansion CTE is blended with a glass ceramic material having a positive CTE in a mill to prepare a sealing paste. The obtd. paste is applied on the surface of a base body 22, on which an optical member 26 is arranged. The paste is heated to the temp. to form a seal during the seal is formed between the member 26 and the base body 22. The base body 22 is preferably β-eucryptite, and at least most of the glass ceramic material added in a mill is a pyrophosphate glass ceramic material having a negative CTE.

    Abstract: A fusion sealing material containing a mill addition, a sealing tape cast from the material, and a method of producing the tape. The material is composed of a low temperature glass, a mill addition that lowers the effective coefficient of thermal expansion of the glass in a seal and an organic medium. The sealing tape is prepared by hot mixing the solids with a liquefied medium, such as a high melting alcohol, and casting the hot mix onto a cold sheet to immediately solidify the medium.

    Abstract: The invention relates to a method for controlling the conductance of heated structures used to initiate faster light-off in emission control systems such as used for automotive catalytic converters, diesel particulate filters and industrial stacks and other applications in which the exhaust gas stream temperature is too low to initiate fast light-off. The invention also relates to an exhaust gas apparatus useful for achieving early light-off of catalytic converters comprising a cellular substrate having a layer of conductive material formed thereon and means for activating the device by passing electric current or by exposing the device to an electromagnetic energy field.
