Title: Frequency detection circuit
Inventor: URABE KENZO
IPC: H03D3/00
Filed: 1995-04-28
Abstract: PURPOSE: To provide a frequency detection circuit which has a small circuit scale to be suitable for an IC. CONSTITUTION: An orthogonal detection circuit 1 orthogonally detects a reception signal IN to send an in-phase component signal (i) and an orthogonal component signal (q). The circuit block of an analog polarity switching circuit 12 to which a clock signal CI is inputted, an analog polarity switching circuit 13 to which a clock signal CQ whose phase leads that of the clock signal CI by π/2 is inputted, an adder 14, a band pass filter 15, and a level comparator 16 digitizes the frequency conversion signal of the reception signal IN to a binary and sends it to exclusive OR gates 17 and 18. Exclusive OR gates 17 and 18 and running average circuits 19 and 20 obtain data I and Q indicating the phase differences between the digital signal and clock signals CI and CQ.  A difference circuit 21 obtains the change with time of data I, and a digital polarity switching circuit 22 switches the polarity of this change with time by the most significant bit value of data Q to send a detection output OUT.

Title: Storing method of cassette tape
Inventor: HATSUTORI KIWA
IPC: G11B5/008
Filed: 1982-07-23
Abstract: PURPOSE:To eliminate completely the hearing feeling problems when a sound record program is reproduced, by using two signals having a 180 deg. phase difference and the same frequency and same sound recording level to form a division discriminating signal, using one of these two signals as a detecting signal to control a tape winding machine and therefore raising up the recorded level of a Q signal. CONSTITUTION:As shown in the figure,a Q signal detecting mechanism of a tape winding machine divides magnetically the width of a track into two parts to record signals 14a and 14b having phases opposite to each other for each half track. A half track reproducing head 21 is used to detect one of the signals 14a and 14b. In such a way, a division discriminating signal is formed with two signals having a 180 deg. phase difference and the same frequency and same recording level. This discriminating is recorded by dividing magnetically a track of a tape into two parts. Therefore both signals negate with each other when a cassette tape is produced.

Title: Method for determining failed section of underground transmission line
Inventor: HARA MAKOTO
IPC: G01R31/08
Filed: 1988-05-27
Abstract: PURPOSE:To make it possible to determine a failed section instantaneously and accurately even for one circuit of three-core cable, by measuring the voltage drop in a sheath at a specified interval, detecting a sheath current, and determining the failed section by the comparison of the values at a plurality of points. CONSTITUTION:When any of conductors 4 and sheath 6 are shorted, a sheath current flows through the sheath 6. The voltage between terminals 7 and 7 at both ends of a connecting box is measured with a voltage detector 9. The voltage is amplified and transduced into a light signal with an electricity/light transducer 11. The signal is transmitted to a central judging device through optical fiber cable 12. In the central judging device, the transmitted light signal is regenerated into the current value and the current phase. These values are stored, compared and operated. The absolute value and the phase of the sheath current are changed before and after the grounded point. Based on this fact, the obtained sheath currents are compared at a plurality of points, and the changing point is obtained. The part corresponding to the changing point is judged to be the grounded section. Since a current feeding patter of the objective underground line is known, the level distribution and the phase of the sheath current in the longitudinal direction are detected, and the grounded point is determined.

Title: Electromagnetic induction equipment
Inventor: YONEDA MASATO
IPC: H01F38/28
Filed: 1992-05-22
Abstract: PURPOSE:To obtain electromagnetic induction equipment which is free of output error and waveform strain by starting the winding of a winding along a magnetic passage all over the circumferential surface of the magnetic passage and then rewinding the remaining turns of the winding along the same magnetic passage in the opposite and ending the winding at the same position at which the winding starts. CONSTITUTION:When a winding 2 to be wound in N turns is wound around a winding core 1 of a through type current transformer by one state, the winding is wound clockwise by N/2 turns from the side of k along a magnetic passage in such a fashion that the winding may be equally distributed up to a turn-around position. Next, the winding is wound by the remaining N/2 turns counter clockwise along the magnetic passage from the turn-around position in the same winding direction in such a fashion that the winding may be equally distributed up to the winding starting position (the side of 1), thereby rewinding equally the winding 2 whose turns total to N times by N/2 turns along the magnetic passage. This construction makes it possible to prevent the formation of a closed loop circuit with through magnetic flux.
