A compound represented by a general formula (1) ABXn (where A is a carbon-containing group; B is at least one element selected from Si, Ge, Sn, Ti and Zr; X is a hydrolyzable group; and n is 1, 2 or 3), for example, a chlorosilane compound having a fluorocarbon group, is measured in an amount required for one time application, and dropped from a nozzle on a surface of a substrate having an active hydrogen on the surface, and simultaneously it is rubbed with a coater made of a sponge or a nonwoven fabric, etc. Furthermore, it is rubbed with a coater made of a sponge or a nonwoven fabric, etc. while blowing a dry warm air, and an elimination reaction is caused between the active hydrogen on the surface of the substrate and the hydrolyzable group of the compound. Thus, the compound is covalently bonded to the substrate. The molecules of the silane compound also are polymerized with one another to be fixed. Thus can be provided a coating film and a method and an apparatus for producing the same, in which: an amount of a liquid required for forming a film is decreased even when the substrate has an irregular shape and a large size; it is not necessary to be concerned for the pot life of a coating solution; the substrate is manipulated easily; and cost is low.

There is provided an extrusion head that is capable of largely increasing a production speed rather than a conventional head that extrudes supplies a high viscous melt-coating composition. In an extrusion head 12 that comprises a die ring 12 having an exit portion 122 and a nipple 13 arranged in vicinity of the exit portion 122, whereby a core wire passage 131 is provided to an inside of the nipple 13 in an axial direction, and a high viscous melt-coating composition is pressure-fed into a space, which is formed by the die ring 12 and the nipple 13, toward the exit portion 122 while drawing out a core wire W from the core wire passage to the exit portion, and thus a cord-like coated core wire is extruded from the exit portion 122 of the die ring while coating the core wire W with the high viscous melt-coating composition, a stagnation reservoir of the high viscous melt-coating composition is provided in vicinity of the exit portion by providing a wall surface 121 perpendicularly to a proceeding direction of the core wire W at the exit portion 122.

The invention provides a defect inspecting apparatus and a defect detecting method for specifying a position of a defect before polarization when the defect is included in a coaxial flexible piezoelectric member. Further, when a piezoelectric tube is moved in polarization, a friction force is produced between the coaxial flexible piezoelectric member and a block-like conductor and therefore, a large force is needed in moving the piezoelectric tube. The invention provides a polarizing apparatus and a polarizing method capable of moving the piezoelectric tube even by a small force.There are provided a defect detecting apparatus of a coaxial flexible piezoelectric member having a constitution of applying a direct current to a coaxial flexible piezoelectric member while moving a piezoelectric tube arranged at a hole of inspecting electrode means and a marking apparatus for marking a defect portion. Thereby, when a defect is present at a portion thereof arranged at the hole of the inspecting electrode means, electricity is discharged at the defect portion and therefore, the defect portion can be specified and the mark can be attached to the defect portion. Further, a conductive block provided with a path portion of the piezoelectric tube is divided. By dividing the block-like conductor by a plural number, a friction force between the block-like conductor per divided one and the piezoelectric tube is reduced. Further, the piezoelectric tube can be moved by a small force by a pulley arranged at a fold back portion of the piezoelectric tube.
