A connector for a flat cable comprises a housing including a rectangular-shaped base portion defined by opposite first and second sides and opposite third and fourth sides and first and second side walls provided on the third and fourth sides. A plurality of first contacts each has a first contact convex and a first lead terminal. First contacts laterally extend from the first side toward the second side. First lead terminals project outward from the first side. First contact convex portions face upward and are provided at inner and top end portions of the first contacts. A plurality of second contacts are provided, each of which has a second contact convex and a second lead terminal. Second contacts laterally extend from the second side toward the first side. Second lead terminals project outward from the second side. Second contact convex portions face upward and are provided at inner and top end portions of the second contacts. Second contacts are discontinuously aligned at a second pitch. Each of the second contact convex portions are positioned between adjacent two of the first contact convex portions so that the first and second contact convex portions alternate with each other. A lever is further pivotally attached to the side walls of the housing. The lever has an engaging portion which is spaced over the first and second contact convex portions for sandwiching a flat cable between the engaging portion and the first and second contact convex portions.

A connector comprises a socket portion which is subjected to surface treatment and a base portion which is not subjected to the surface treatment, or comprises a socket portion and a base portion subjected to different kinds of surface treatments. The socket and base portions are each provided with a coupling mechanism. The socket and base portions may be easily surface treated independently, after which they are coupled together, thereby forming a connector capable of preventing short circuit arising from surface treatments.

A mounting unit of a second flexible circuit board is arranged on a rear surface side of a liquid crystal display panel. A portion of a first flexible circuit board at which a connection terminal is formed is bonded to an end portion of a display surface side of the liquid crystal display panel, is pulled out from the end portion of the liquid crystal display panel, is bent and overlapped with the opposite surface to the surface where the light emission components of the mounting unit are mounted with a space, and an external terminal is arranged on the rear surface side. An extended portion is pulled out from the mounting unit, is bent so as to return to the direction of the mounting unit, and is overlapped with the first flexible circuit board on an outer surface of the first flexible circuit board.

A sheet material for a radio wave absorber and a radio wave absorber formed from the sheet material, where the sheet material is light weighted and has excellent form-retaining capability and workability for field assembling. A sheet material (1) for a radio wave absorber has a corrugated paperboard structure with an undulated corrugated medium (2) and a planar liner (3) that are layered over each other. The corrugated medium (2) and/or the liner (3) are constructed from a sheet including an electrical-loss material. A radio wave absorber (10) is characterized in that the sheet material (1) for a radio wave absorber is cut, folded, and assembled as a hollow three-dimensional structure body, which has a shape of wedge, polygonal pyramid, or polygonal cylinder.

A method of surface-mounting a connector on a circuit board using a rivet as a mounting member is provided. This method can provide an excellent assembling process by, if necessary, using the conventional solder dipping process or rivet caulking process. A rivet has a middle portion acting as a flange. In the rivet, one end is previously fixed to a connector side while the other end is inserted into a first hole formed in the surface of a circuit board, so that the flange can be closely attached to the circuit board. Particularly, since a soldering pad is formed adjacent to a hole formed in the circuit board, the rivet can be bonded to the circuit board while other electronic components are being surface-soldered on the circuit board.

Fuel vapor is prevented from leaking to the outside during refueling, and even when an air space is formed in an upper portion of a fuel filler pipe, a diagnosis of leakage of fuel vapor can be performed with good accuracy.During refueling, fuel vapor is guided from a fuel tank 1 to a canister 3, and is absorbed by the canister 3. A change in the internal pressure of a fuel vapor path including the fuel tank 1, a fuel vapor pipe 4, and the canister 3 is detected by a pressure sensor 8, thereby performing a diagnosis of leakage of fuel vapor. An upper space 16 in the fuel tank 1 and an upper space 17 in a fuel filler pipe 2 communicate with each other through an airflow resistance pipe 12, and in order to restrict flow of fuel vapor from the fuel tank 1 through the airflow resistance pipe 12 into the fuel filler pipe 2 during refueling, the airflow resistance pipe 12 includes an orifice 13.
