  • Publication number: 20090029598
    Abstract: A board connector has a plurality of contacts, an insulator holding the plurality of contacts, and a shell covering at least a part of the insulator. Each contact has an SMT terminal to be connected to a wiring pattern on a board. The insulator has a first insulator portion extending in an X-direction and two second insulator portions each extending in a Y-direction perpendicular to the X-direction. The first insulator portion has a bottom surface and first ends in the X-direction. Each second insulator portion has second ends. Each second insulator portion extends from the first ends to the second ends, respectively. The second ends are positioned on an imaginary straight line. The first insulator portion, the second insulator portions, and the imaginary straight line define a predetermined area. The SMT terminals are held by the insulator so that the SMT terminals are positioned within the predetermined area.

  • Publication number: 20090011623
    Abstract: An electrical connector mountable to a circuit board is disclosed. The disclosed connector includes a shell which comprises a first plate-like portion, a second plate-like portion and connection portions. The first plate-like portion extends in a predetermined direction and is provided with fixed portions at opposite ends thereof in the predetermined direction. The fixed portion is to be fixed to the circuit board. The second plate-like portion extends in the predetermined direction. Each of the connection portions connects the first and the second plate-like portion. The second plate-like portion is provided with force resist portions at opposite ends thereof in the predetermined direction. The force resist portions are configured so that, when a force is applied to the electrical connector along a direction from the first plate-like portion towards the second plate-like portion, the force resist portions resist the force.

  • Patent number: 6374209
    Abstract: A text input section (1) divides an inputted text into sentences and attaches a number to each of the sentences, which is stored in a text data base together with the number. An important word recognizing section (2) generates a list of important words for each sentence to store it in a storing section (8). An important word weighting section (3) weights each important word. A relation degree computing section (4) computes a relation degree between an attention sentence and a precedent sentence. An important degree computing section (5) computes an importance degree of each attention sentence. A tree structure determining section (6) determines a parent sentence of the attention sentence and determines a tree structure of the inputted text.
