摘要:
An aromatic polyester film, which comprises an aromatic polyester comprising 2,6-naphthalenedicarboxylic acid as the main dicarboxylic acid component and 1,3-propanediol as the main diol component and having a density of at least 1.310 g/cm3. A laminated film comprising another polyester layer can be formed from this aromatic polyester film. An aromatic polyester containing a small amount of a sulfonic acid phosphonium salt used as one of the aromatic polyesters forming this laminated film is excellent in electrostatic casting properties and resistance to the contamination of an electrostatic wire, and an aromatic polyester containing an inorganic anti-fungus agent is used for antifungal application.

In a method for winding a toroidal coil, a winding of a first layer is made by means of repeating the following three steps. At a first step, one end of a wire is inserted into a central aperture of a core from one side thereof to extend the wire along an axial direction of the core; the other end of the wire is abutted to one surface of the core such that the other end is radially extended; and a tension is applied to the wire and the core with the other end of the wire is then turned in a diametrical direction of the core perpendicular to the radial direction. At a second step, the one end of the wire is inserted into the central aperture of the core towards the other side; and the tension is applied to the wire and the core is then rotated at a desired angle in one direction on a central axis of the core. At a third step, the core is grasped again by core turning means to turn the core in the same direction; the one end of the wire is inserted into the central aperture of the core towards the one side thereof, the one end being extended and the tension being applied to the wire, and then the core is rotated using the core turning means to shift it back at the desired angle in the other direction opposite to the one direction.

摘要:
The etching selectivity is controlled by appropriately changing the dimension of the opening of each contact holes in forming simultaneously a plurality of contact holes of different depth by etching. By forming a dent in advance underlying the region where a contact hole is to be formed, the depth of the contact hole can be increased, whereby difference in the depths of the plurality of contact holes can be reduced. As a result, damage in the underlying layer or under etching in forming a plurality of contact holes of different depth simultaneously by etching can be solved.
摘要:
This invention is an apparatus for drying and burning high-hydrous combustible solids comprising: a hopper for containing high-hydrous combustible solids; a drier for drying said high-hydrous combustible solids when transported from said hopper to said drier 1; a combustion chamber for receiving and burning dried solid from a transportation tube; and a means to lead the waste gas from said combustion chamber to said drier to be used as drying gas. High-hydrous combustible solids are transported to furnace the combustion chamber immediately after being dried in the drier, and the waste gas from the combustion chamber is used as drying gas in the drier.
