摘要： PROBLEM TO BE SOLVED: To detect a portable radio equipment even in a waiting state by detecting a radio wave radiated from a portable radio equipment whose power is turned on, and detecting the existence of the portable equipment. SOLUTION: A portable radio equipment 1 such as a portable telephone set radiates an unnecessary weak radio wave even in a waiting state when the power is turned on. Also, at the time of receiving a response request signal, the radio wave is automatically transmitted. This transmitted radio wave is received by a receiving antenna 2, and the frequency and level are detected by a wide band receiver 3. The frequency and level detected by the wide band receiver 3 are referred to by a computer 4 with a data base 5 in which the information of the portable radio equipment 1 such as each kind of portable telephone set is stored. When it is judged that the radio equipment 1 such as the portable telephone set whose power is turned on is present according to the frequency and level of the received radio wave, the owner or the manager of the building or room is let know the existence by a warning device 6.

摘要： PURPOSE:To measure static electric charge distribution and electric field distribution conditions inside an object of two dimensions having recessed/projected portions and an object of a three-dimensional shape, by moving in revolution a probe of a surface potential measuring meter circumferentially around an electrically charged object to be measured, and moving the probe linearly at an arbitrary point on the circumference to conduct the measurement of potential distribution. CONSTITUTION:An x-y coordinate system which has an arbitrary point as the origin is set on the same plane with respect to the section 7 of an electrically charged object 6. The rotary axis of a probe rotary movement device 4 is made to coincide with this axis, and the circle for the movement of a probe 2 is positioned on the x-y coordinates plane. On a straight line which is separated from the coordinates origin by a distance (h), potential distribution is measured with a space (d) while the probe 2 is being moved by means of a probe linear movement device 3. The device 4 is rotated in order, and measurement is made until potential differences on respective lines which are symmetrical with respect to the origin, are obtained at all of the peripheral of the object 6, and potential data are sent to a processor 5. The processor 5 estimates the electric field distribution of the section 7 of the charged object 6 by processing electric field distribution data from a potential measuring meter 1.

摘要： PURPOSE:To attain the application of an accurate calling record including the dates, the addresses and the charge of calls, by storing the call charge or the number of a calling subscriber under the control of a signal control circuit into a memory and reading out the storage contents of the memory by a switch to display them on a display device. CONSTITUTION:The call charge signals sent from a network in a busy mode are sent to a signal control circuit 5 via a terminal 1, a power separation/ balance/unbalance converting circuit 2 and a network interface circuit 4. The circuit 5 transfers the call charge signals to a display driving circuit 15 to start this circuit. Thus the call charge is displayed on a display device 14 in a different area since the telephone number of the remote side is already displayed on the device 14 in an originating mode in the form of the dial monitor. The call charge signals delivered in a ring-off mode are also displayed on the device 14 in the same way. Then the ring-off mode is discriminated. If no ring- off mode is decided, a call charge waiting state is set again for the next input of the call charge signals. While a storage processing is started when the ring- off state is decided.

摘要： PURPOSE:To mount a shield structure with an automatic winding machine by providing another winding between the windings of a transformer having a plurality of windings, grounding the one end of the windings and opening the other ends thereof. CONSTITUTION:In a shield structure, a shield winding 6 is wound between the primary winding 1 and the secondary winding 2, with the one end of shield winding 6 grounded and the other end opened. The shield winding 6 mush be wound with less number of turnings and without any gap using a thick lead wire from the point of view of the property of inducing a voltage on such coil. Otherwise, a number of turns is reduced by forming a shield winding 6 using two lead wires wound in parallel. In this case, gap is eliminated in actual. Thereby, windings can be formed with the automatic winding machine including the shield structure and accordingly an economical transformer can be realized while keeping the desired shield effect.

摘要： PURPOSE:To facilitate the generation of an optimum identification clock signal which has less jitters without the influence of pattern jitters by detecting phase synchronization after the phase of an input waveform is synchronized, and then using the output of an identifier thereafter for phase synchronization. CONSTITUTION:The clock signal is extracted while phase-synchronized with the rising of an initially rectified reception signal, and a detector 17 detects the point of time when the phase is synchronized. Then, the phase synchronization is controlled thereafter by using only the rising phase at a change point from 0 to 1 with identification information outputted from the identifier 6.

摘要： PURPOSE:To easily specify the cause of the electromagnetic hindrance by measuring the inner and surrounding electromagnetic environment of an electronic device, and recording the data regarding electromagnetic hindrance waves together with the detection time in buffer memories as appropriate. CONSTITUTION:A sensor 3 detects electromagnetic hindrance waves propagated in the space, conducting hindrance waves propagated on the communication line and power line of an electronic device 1 and the noise voltage induced in the internal circuit of the device 1 and send them to a measurement section 4. Measured data regarding the electromagnetic hindrance waves are formed in the measurement section 4 and sent to buffer memories 8-n together with detection time data. A hindrance detecting device 9 detects the hindrance generated in the device 1 and sends an alarm signal to an analyzing device section 10. The device section 10 selects only the portions with the preset level or above among the data in the memories 8-n and sends them to a nonvolatile memory 11 after compression.

摘要： PURPOSE:To correctly measure a communication line terminal disturbing wave voltage of a communication equipment having 4 communication line terminals or above by measuring the communication line terminal disturbing wave voltage between an electric neutral point of a duplex line and ground. CONSTITUTION:An attachment 17 composed of a couple of impedance elements 15 is fitted between the dummy communication terminal 55 of each of 2-wire using dummy communication circuit networks 53 and a communication line terminal disturbing wave voltage measuring device 56. When a voltage generated between an interconnecting point of the impedance element 15 being an electric neutral point of the duplex line and ground is measured by the disturbing wave voltage measuring device 56, a current resulting from a current flowing to the duplex line does not flow to the disturbing wave voltage measuring device 56. Thus, even when plural number of two-wire using dummy communication circuit networks are connected for the measurement, no measuring error is generated and the accurate communication line terminal disturbing wave voltage is measured for 4-wire communication line terminals or above.
