Title: Receiving circuit for active sonar system
Inventor: KANDA KATSUMI
IPC: G01S7/529
Filed: 1986-06-06
Abstract: PURPOSE:To display even a continuous signal while improving the echo sound detecting ability of a target by providing a receiving circuit with a reception gain control, and detecting a continuous wave in a gain-controlled received signal and displaying it. CONSTITUTION:Received signals in respective directions are added together while delayed by a phase matching circuit 102, and then supplied to a receiving and amplifying circuit 103 with reception sensitivity. This circuit 103 is made low in gain to a large-level received signal reflected by the surface of the short- distance sea right after the signal is controlled by an automatic gain control circuit 104 and transmitted, and the dynamic range of the received signal is narrowed down according to the dynamic range of a display 107, so that the display is made easy to see. Further, part of the output of this circuit 103 is processed by a continuous wave detecting circuit 108 to obtain the continuous signal of the sailing tone, etc., of a ship after in-sea noises, etc., are removed, and the signal is supplied to the display device 107 through an adding circuit 105 together with the output of the circuit 103. Therefore, while the echo sound detecting ability of the target is improved, even the continuous sound signal is detected.

Title: Fault monitoring system for network element
Inventor: SUZUKI MARI
IPC: H04L12/28
Filed: 1997-05-02
Abstract: PROBLEM TO BE SOLVED: To check a communication state by reading the port state of adjacent network element(NE) before the periodical transmission of polling signal to the NE out of a data base saving data periodically collecting adjacent NE information and port information from the NE. SOLUTION: An NE 101 has an ID 102 of adjacent NE, port state 103 and its own ID 106 as memory data 105. At the time of initial setting, a network monitoring device 111 and a network information generating function 113 save the data collecting the ID 102 and port state 103 of adjacent NE from the NE 101 in a network configuration data base 116. A polling function 115 periodically transmits the polling signal to the NE 101 and before checking the state of NE, the port state 103 of adjacent NE is read out of the data base 116. Thus, a communication check function 117 can quickly recognize communication interruption without outputting the polling signal.

Title: Diffusion joining method of aluminum
Inventor: KIYOFUJI SHINICHIROU
IPC: B23K20/00
Filed: 1983-07-20
Abstract: PURPOSE:To join diffusively exposed clean joint surfaces to each other while suppressing plastic deformation by plating Zn to the clean surfaces while removing the Al oxide film on the Al (alloy) joint surfaces in an NaOH soln. then evaporating and removing Zn in a joining atmosphere. CONSTITUTION:The above-described Al oxide film is treated in a zinc-replacement plating liquid consisting essentially of NaOH and ZnO so that the clean surfaces are subjected to zinc-replacement plating B while the Al oxide film is removed therefrom. The Al (alloy) joining members A subjected to the plating B are spaced from each other at a slight distance and are charged into a joining device. The inside of the device is thereafter evacuated to a vaccum and is heated up to the joining temp. The degree of vacuum in the device in this stage is maintained under the degree higher than the vapor pressure of Zn at the joining temp. to expose the clean joint surfaces by evaporation of Zn on the joint surfaces. The joint surfaces in such a state are quickly pressurized to each other and are maintained at the joining temp. for a specified time to eliminate the joint surfaces so that the joining members A, B are united to one body by the diffusion joining with a small rate of plastic deformation.
