Abstract: An object is to provide a sash coupling structure and a method for sash coupling that ensures omission of the process. The sash coupling structure is made such that on a door frame constituted of a column and an upper sash, a coupling cross-sectional surface of the column and a coupling cross-sectional surface of the upper sash are butted together. The column is constituted of a channel member and an inner member. The channel member and the inner member include adhering portions coupled one another along a longitudinal direction. The inner member is plated. A non-adhering portion, which faces a non-not-yet-adhering portion of the inner member, is formed on the channel member at a butted coupling portion.

Abstract: A vertical sash of a vehicular door frame includes a channel member defining a glass run accommodation space and an inboard-side member having a pocket portion disposed on the inboard side of the channel member. An inboard-side opening edge portion of the channel member and a pocket edge portion of the inboard-side member are joined together. At least one of the channel member and the inboard-side member is plated. A space is provided between the outer surface of the inboard-side opening edge portion of the channel member and the inner surface of the pocket edge portion of the inboard-side member. The space extends in a longitudinal direction and is open at the distal ends of the edge portions. Laser welding is performed along the space.

Abstract: Alkaline earth metal basic silicate particles having a silicate of an alkaline earth metal on the surfaces of the alkaline earth metal hydroxide particles, and having an SiO2/MO (M is an alkaline earth metal) molar ratio as a whole in a range of from 0.01 to 0.90. The particles are useful as a stabilizer for the chlorine-containing polymers.
