A contact element (4) comprises a fixed section (5) inserted into the slot (2) along the first minor side of the slot, a flexible section (6) extending from the fixed section toward the second minor side of the slot in a plane and being flexible in the plane, and contact portions (7A, 7B) extending from the flexible section so as to project from the major faces of a housing (1). The fixed section, the flexible section, and the contact portions are in the plane parallel to the major faces of the slot. A conductive layer or sheet (3) is provided on the major sides of the slot. A sliding contact (8A, 8B) are provided near the contact portions are brought into sliding contact with the conductive layer or sheet.

A transmission board (10) comprises a frame body (30) and a surface board (20) supported by the frame body (30) and having a transmission circuit. The frame body (30) has plugging edges (33, 34) that project from the edges of the surface board (20) for guiding the terminals of mating connectors to connection pads on the surface board (20). The plugging edges have guiding slopes 33A and 33B, and 34A and 34B. At least the plugging edges of the frame body (30) are made of a metal or resin molding.

In a transmission circuit board, ground terminal portions (10) are disposed at every other two rows in both end columns. Each of signal circuit layers (20) includes at least a pair of adjacent signal connecting portions electrically connected to a pair of the wiring portions (21, 22) arranged in parallel in a row direction and the column direction different from those on an adjacent signal circuit layer. Each of the ground layers is electrically connected to at least one of the ground terminal portions (10) in the both end columns.

A game where in a plan view, the view point and the view direction are set so that both of the player character and the boss character are included within a horizontal visual field and that the virtual camera observes the boss character from behind the player character. In the elevation view, the view point and the view direction of the virtual camera are set so that they are moved into below the player character when the boss character enters over the horizontal line in the area of vertical visual field angle. Therefore, the operation of fighting against the boss character is simplified without different feeling from the fighting against the trivial characters, with securing the dynamics and interest as a game.

An electrical connector for connecting to a mother board a daughter board having a plurality of pads on a front edge thereof includes a plurality of contact terminals made by stamping and bending a resilient conductive sheet so as to provide first and second retaining sections which are fixed to the insulating housing. The daughter board is inserted between upper and lower contact portions of the contact terminals with a zero-insertion force and then rotated to bring the pads into contact with the contact portions with a predetermined contact force.

The present invention involves connectors for reducing Far-End Crosstalk (FEXT) through the use of novel polarity swapping to negate the cumulative effect of FEXT. Skew adjustment is used to improve the FEXT cancellation from polarity swapping. The polarity reversal location or locations among FEXT sources are optimized to achieve maximum FEXT cancellation. The novelty polarity swapping technique can be applied to a wide variety of connectors, such as mezzanine connectors, backplane connectors, and any other connectors that can benefit from FEXT reduction.

An electrical connector (10) has ground planes (13). Each ground plane (13) crosses counter ground planes (36) of the counter connector (30) so as to make a lattice structure when the counter connector (30) is fitted to the connector (10). The contact section (12C) of a signal terminal (12) of the connector (10) has a plane surface perpendicular to the surface of the corresponding counter contact section (34A) of the counter signal terminal (34), and formed at a flexible elastic arm (12B) in the plane surface. The ground plane (13) has pressure-welding sections (18B) and (20B), which individually elastically contact with the facing inner surfaces of each slit, at a portion to be put into each slit of the counter ground plane (36).
