摘要： A coordinate position detection device according to the present invention includes: charging circuits having both the capability of charging a coupling capacitance in a capacitive-coupling touch panel with a position-detection resistive film whose potential periodically varies between a positive potential and a negative potential and the capability of restoring the charged coupling capacitance to its state prior to charging; current-to-voltage conversion circuits converting into a voltage the total amount of charging currents of the coupling capacitance after the charging circuits supply the charging current to the coupling capacitance a plurality of times; and a computation device detecting the coordinate position of a touched area based on the outputs of the current-to-voltage conversion circuits. The coordinate position detection device is characterized in that the number of charging operations performed when the potential at the position-detection resistive film is positive is substantially equal to the number of charging operations performed when the potential at the position-detection resistive film is negative. With this configuration, it is possible to improve the accuracy with which the coordinate position of a touched area is detected even when the potential at the position-detection resistive film periodically varies.
摘要翻译：根据本发明的坐标位置检测装置包括：充电电路具有将电容耦合触摸面板中的耦合电容充电的能力与其电位周期性地在正电位和负电位之间变化的位置检测电阻膜;以及在充电之前将充电耦合电容恢复到其状态的能力; 电流 - 电压转换电路将充电电路的充电电流多次提供给耦合电容，从而将耦合电容的充电电流的总量转换为电压; 以及计算装置，其基于所述电流 - 电压转换电路的输出来检测被触摸区域的坐标位置。坐标位置检测装置的特征在于，当位置检测电阻膜的电位为正时进行的充电操作的数量基本上等于当位置检测电阻膜的电位为负时执行的充电操作次数。利用这种配置，即使当位置检测电阻膜的电位周期性变化时，也可以提高检测到触摸区域的坐标位置的精度。

摘要： A bicycle pedal assembly has a cleat releasably coupled to a pedal by a cleat engagement mechanism formed on an upper surface of its pedal body. The pedal body has a front end configured and arranged to include a sole guide portion that assists the rider in rotating the pedal body about its pedal shaft. In one embodiment, the sole guide portion is formed by a first concaved sole receiving recess located in a tip surface of the pedal body and a second concaved sole receiving recess located on the upper surface of the pedal body adjacent to the tip surface. Alternatively, the concaved sole receiving recesses can be replaced with either a pair of laterally spaced projections located on at the front end of the pedal body, or a V-shaped tip surface.
