Title: Method and apparatus for radio direction finding
Inventor: WATANABE MIKIO
IPC: G01S3/62
Filed: 1983-07-01
Abstract: PURPOSE:To enable judgment on the clear directivity even with respect to a fast and non-continuous radio wave by a method wherein the current demodulation signal is compared with the one preceded by fixed cycle to select the maximum signal and a combined output is detected and outputted. CONSTITUTION:An detection output demodulated with an orthogonal loop antenna 1, a goniometer 2, a detector 4 and the like is compared with a detection output via a delay circuit 10 by a signal combining circuit 11 to select the maximum signal value. Then, a combined signal by a detection output envelope is formed from the maximum signals at respective points and fed to a demodulation circuit 5 as detection output to indicate the incoming direction of a radio wave on a Braun tube display 8. With such an arrangement, a fast and discontinuous radio wave can be processed as the normal discontinuous radio wave is done thereby enabling a clear decision on the incoming direction with respect to the fast and discontinuous radio wave as well.

Title: Network control circuit
Inventor: NAKAYAMA NORIO
IPC: H04N1/00
Filed: 1990-05-12
Abstract: PURPOSE:To simplify the control of the detection of a DC loop and the detection of a call signal by providing a DC loop supervisory means, a dial pulse generation means, a call signal detection means, two delay circuits, a flip flop circuit and a gate. CONSTITUTION:The first delay circuit 10 which operates as the delay circuit only when the DC loop detection signal (a) transits from H to L, a second delay circuit 11 which operates the delay circuit only when it transits from L to L, the flip flop circuit 12 of a set/reset type and the gate circuit 13 are combined. Thus, the open of the DC loop within prescribed time when the DC loop is closed and the close of the DC loop within prescribed time when the DC loop is opened can be ignored and the call detection signal (b) is gated by the output signal of the flip flop circuit 12. Thus, influence for the call detection signal (b) at the time of a pulse dial can be neglected. Thus, the detection of the DC loop and the detection of the call signal are extremely simplified and the possibility of malfunction is excluded.

Title: Device and method for reducing ground voltage
Inventor: SILVERBERG MICHAEL H
IPC: H03L1/00
Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To reduce power line noise by lowering the voltage between a ground point and a neutral reference point by positioning the neutral reference point at a distance from the ground point and exciting the ground point according to the neutral reference voltage at the neutral reference point. SOLUTION: An input terminal 806 is a very-high-impedance terminal, so substantially no current flows between the input terminal 806 and ground point 610 and the voltage at the input terminal 806 becomes substantially equal to the voltage at the ground point 610. Consequently, voltage drop effect caused by an induction element 822 is substantially removed. A buffer amplifier 802 responds the signal of the frequency band of a power line signal transmitter receiver and when the voltages at input terminals 804 and 806 are different, an output terminal excites the ground point 610 through the induction element 820.  The output voltage range of the buffer amplifier 802 is normally larger than the voltage difference appearing between the ground point 610 and neutral reference point 328, so the buffer amplifier 802 excites the voltage at the ground point 610 and equalizes it to the voltage at the neutral reference point 328.

IPC: G06F12/16
Filed: 1987-05-18
Abstract: PURPOSE:To improve the data processing efficiency by testing an entire memory related to the data processing with a single detection of the memory abnormality for detection of an abnormal memory and storing the address of said abnormal memory. CONSTITUTION:A means to test the overall normal/abnormal states of a memory related to the data processing when the abnormality of a memory occurs during the normal data processing and a means to store the position of the abnormal memory are provided. When the memory abnormality occurs and the data processing proceeds to an interruption process, the reading/writing actions are given to the entire memory related to the data processing for the test of the normal/abnormal states of the memory. Then the position of the detected abnormal memory is stored. Based on this detection data, an operator corrects the abnormality of the memory. Thus the entire abnormality of a memory is detected in response to the data processing just with a single detecting action of the memory. As a result, the data processing efficiency is improved.

IPC: H01L27/00
Filed: 1990-05-11
Abstract: PURPOSE:To reduce the resistance of wiring and to prevent a discontinuity in a lower layer device and the damage to an element from being generated by a high-temperature heat treatment of an upper layer device by a method wherein a low-resistance and low-melting point metal is used for the wirings of the lower layer device and the wirings are surrounded with a high-melting point substance film. CONSTITUTION:A 1000-Angstrom  thick titanium nitride film 43 is formed by a reactive sputtering method and a 8000-Angstrom  thick tungsten film 45 is formed by a selective CVD method. For example, as the lower parts of low-melting point metal (660 deg.C.) A1 wiring are isolated from a silicon substrate by the film 43 of a melting point of 2950 deg.C. Therefore, the contact between the A1 wiring and the silicon substrate is protected from damage because the A1 wiring is not converted to silicide during a high-temperature heat treatment. Moreover, as the upper parts of the wirings A1 are covered with the film 45 of a melting point of 3377 deg.C, it is prevented that the A1 wirings are agglomerated at the time of solidification by the large surface tensions (a bed wetting) of a melted A1 wiring 44 and an oxide film 22 and a disconnection is generated in a lower layer device.
