    • The electrical connector in accordance with the present invention may be used for signal transmission/reception between a card and a circuit of a machine concerned, for example. The electrical connector has a frame to which attached are a rear structure having a card inserting/pulling port and a connector body having a contact group. Also attached to the frame are a longitudinally movable slider and a shaft having a swing fulcrum. The slider has engagement pawls adapted to be engaged with a card, and the shaft has an operating knob having a card holding portion. When the slider advances with the insertion of a card, the shaft is swung so that the operating knob is pushed out and the holding portion comes in contact with the rear end surface of the card, thereby to prevent the card from being erroneously pulled out.
    • 例如,根据本发明的电连接器可以用于卡和所涉及的机器的电路之间的信号发送/接收。 电连接器具有附接的框架,后框架具有卡插入/拉出端口和具有接触组的连接器主体。 另外还附着在框架上的是可纵向移动的滑块和具有摆动支点的轴。 滑块具有适于与卡接合的接合爪,并且轴具有具有卡保持部的操作旋钮。 当滑块随着卡的插入而前进时,轴被摆动,使得操作旋钮被推出并且保持部分与卡的后端表面接触,从而防止卡被错误地拉​​出。

    • A torque wrench having ease of operation compatible with improved accuracy of measurement. The torque wrench includes a tightening portion, a housing having a front side cover part and a back side grip part and a shaft-like strain body that is contained inside the housing. First distortion sensors and second distortion sensors are arranged on the strain body at spaced points in the axial direction of the strain body for measuring an amount of distortion of the strain body. A microprocessor chip has functions including computation of a tightening torque which is corrected for errors due to changes in a point of effort where a tightening force is applied by a user. The correction is based on the detection result of the first distortion sensors and the second distortion sensors. An output portion outputs the corrected tightening torque measurement value.
