A cable clamp which is capable of preventing even a very fine cable to be treated from coming off or extending off therefrom, without any fear of the cable being damaged or broken, and is easy to carry out a clamping treatment and an extra length-bunching treatment on cables, with enhanced workability. According to the present invention, the alignment and probing techniques to improve the accuracy of component placement in assembly are described. The pager of the preferred embodiments is operative to convert the inputted symbols into a text message and transmit the text message to a paging network. Object database stores object records in a search range. A second capacitor is coupled to an inverting input terminal of the first amplifying stage.
