Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a substrate for correcting unbalance and to simplify the constitution by providing a rotary head drum device with terminal members holding plural metallic terminals and adding unbalance collecting weights to these terminal members. SOLUTION: Plural kinds of the unbalance correcting weights 23 formed by sticking tacky adhesive tapes 22 to metallic pieces or resin pieces 21 are formed for every mass and the unbalance correcting weights 23 of the suitable mass are stuck atop the terminal members 9 to make the unbalance possible to be corrected atop the terminal members 9. The external line parts of the front surfaces of the terminal members 9 are provided with splashing preventive step parts 24. The unbalance correcting weights 23 are stuck to the terminal members along the inner side of these splashing preventive step parts 24. Thereby, not only the splashing of the unbalance correcting weights 23 by centrifugal force is prevented but also the variations in the sticking positions in the radial direction of the unbalance correcting weights 23 are absorbed.

Abstract: PURPOSE:To provide additionally a circuit responding to an incoming call signal to an existing telephone set with ease by detecting only the incoming call signal from a signal passing through a telephone line so as to drive an informing device in response to the call signal. CONSTITUTION:A signal obtained from a signal detecting winding 7 of a current transformer 1 is inputted to an amplifier circuit 3, where it is amplified and inputted to a band pass filter passing a prescribed frequency band width using 16Hz as the center frequency. The filter circuit 4 stops the passing of the talking signal and the dial signal passing through a telephone line 8 and only the incoming call signal passes through the band pass filter circuit 4. An output signal of the band pass filter circuit 4 is inputted to a time constant circuit having a time constant of nearly 3sec and when the output level of the time constant circuit reaches a threshold of a level detection circuit 5 being a Schmitt trigger circuit, the output level of the circuit 5 goes to H to drive a driver circuit 6.
