Abstract: A center-channel protector for a vehicle sash door is arranged between a main sash and a center channel. A body of the protector has an H-shaped upper-end surface which is compatible to cover the upper end of the center channel. The body integrally includes a pair of branch covering portions corresponding to a pair of branch portions constituting the center channel and a middle covering portion disposed between the branch covering portions so as to connect the both branch covering portions therewith. An engaging portion is provided with the body and is mechanically engaged, in a direction intersecting a vertical direction, with an engaged portion which is provided with a center channel side. In collaboration with the engaged portion, the engaging portion constitutes a fastening mechanism by which the protector is fastened on the center channel.

Abstract: The invention has for its object the provision of a cleaner capable of removing particles and metal impurities present on the surface of a wafer without corrosion of wirings, gates or the like yet at normal temperature in a short period of time and with a one-pack type solution. To accomplish the above object, the invention provides a cleaner that is an aqueous solution containing phosphoric acid, hydrofluoric acid, and ammonia and/or amine, and having a pH ranging from 2 to 12, wherein the aqueous solution comprises 0.5 to 25 mass % of phosphoric acid, 0.1 to 10 mass % of ammonia and/or amine, and 5×10?3 to 5.0 mass % of hydrofluoric acid.
