Abstract: Provided is a flexible substrate wherein a connection portion between the flexible substrate and an electric circuit board meets requirements of narrow wiring pitch and low resistance at the connection portion. An electric circuit structure, which has the flexible substrate and the electric circuit board to which the flexible substrate is connected, is also provided. A wiring pattern (22) is formed on a flexible base film (21), a connection terminal (25) connected electrically to an electrode terminal of another electric circuit board is arranged at an end portion of the wiring pattern (22), and the connection terminal (25) includes wide connection terminals (25b, 25c) having a terminal width extending across plural lines of the wiring pattern (22).

Abstract: In order to reduce an erroneous operation and electrostatic breakdown resulting from external static electricity, a liquid crystal display device includes: a first pad (341) that is connected to ground wiring provided in a flexible substrate (3) and that is in contact with a rear case (4); and a second pad (342) that is connected to the ground wiring and that is in contact with a front case (5). Here, the first pad (341) and the second pad (342) are provided in a protrusion portion (34) that is sandwiched between a side wall (42) and an external wall (52).

Abstract: A method of isolating and recovering an aromatic carbonate, in which a solvent having a solubility parameter of 7 to 10 is added to a solution of the aromatic carbonate in an aromatic hydroxy compound to precipitate the aromatic carbonate in the form of a crystal and the aromatic carbonate is isolated and recovered.

Abstract: A process for producing a hydrogenation product of a ring-containing unsaturated hydrocarbon polymer, which product is low in the content of the heterogeneous catalyst used.

Abstract: A viscous liquid stirring device comprising a first rotary shaft and a second rotary shaft which are arranged in parallel to each other in the horizontal plane in the vessel. The rotary shafts have a plurality of rotors thereon and are rotated at the same speed and in the same direction that the upper face of the first rotary shaft moves away from the second rotary shaft. A viscous liquid inlet portion is formed on the top portion of the inner wall of the end plate of the vessel.

Abstract: A direct-current motor that facilitates the assembly and mounting of components of the motor, including a front bracket made of synthetic resin and defining recesses. A plurality of metallic brushholders are located in the recesses. The protection of the motor is improved by the waterproofing construction of the motor, including motor cords, and has a sturdy construction.
