Title: Board inspecting device
Inventor: TOKUTANI TERUYOSHI
IPC: G01N23/04
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To extract the mounting image of electronic parts and easily discriminate whether a connection state is conforming or not by picking up an image when X rays are transmitted before and after mounting electronic parts on a board. SOLUTION: A raw board 20 before an IC 21 is mounted is mounted on an inspection stage, and an X-ray transmission image is picked up by a CCD camera. When X rays are transmitted through the board 20, they are attenuated by the thickness of the board 20. The board 20 where the IC 21 with a ball- shaped terminal is mounted on the lower surface of a package as a sample, the image of X rays is picked up by a camera, and the X rays are attenuated by the thickness of the board 20 and the IC 21. By subtracting the image of the ray board 20 from the image of the board 20 where the IC 21 is mounted, the solder image of the IC 21 can be obtained, and the amount of attenuation of X rays of only the IC 21 can be obtained.  The X-ray transmission image of the board 20 before and after the IC 21 is mounted is obtained and the solder image of the IC 21 can be obtained according to the difference in both of them, thus relatively easily discriminating the conformity or non-conformity of the packaging of the IC 21.

Title: Echo canceler
Inventor: NISHIIKE RIKA
IPC: H04B3/20
Filed: 1994-07-22
Abstract: PURPOSE:To correctly evaluate the degree of convergence of an adaptive filter and to optimally control a control factor by correcting a deviation between a residual echo component inputted to 1st and 2nd power calculation sections and a reception signal due to a delay time corresponding to the number of taps of an adaptive filter. CONSTITUTION:A tap factor control section 4 of an adaptive filter 5 obtains a tap factor by the learning identification method based on an output signal of each tap of a delay circuit 1 and a residual echo component. The tap factor and the output signal of each tap of the delay circuit 1 are multiplied by a factor device 2 and output signals of each factor device 2 are added to generate a pseudo echo component and to cancel the echo component in the transmission signal. Then a 1st power calculation section 6 calculates the power of the residual echo component and a 2nd power calculation section 7 calculates the power of the reception signal. A convergence discrimination section 8 discriminates the convergence of the adaptive filter 5 based on the ratio of the power to control the control factor for tap coefficient calculation. Then a correction means 9 corrects timewise deviation in the residual echo component with respect to the reception signal to discriminate the convergence correctly.

Abstract: PROBLEM TO BE SOLVED: To provide an injector capable of controlling rates of fuel injection at multiple stages by sealing a volume part comprising a part of a pressure control chamber with an open/close valve, which opens and closes a fuel delivery passage, with the opening area of the fuel delivery passage of the pressure control chamber kept constant. SOLUTION: A valve element 67 of an open/close valve 65 opens a communicating hole 58 between a first volume part 60 and a second volume part 61 that comprise a pressure control chamber 30 to discharge fuel within he second volume part 61 through the communicating hole 58, and when the valve element 67 of the open/close valve 65 closes the communicating hole 58 with a needle valve 31 lifted to a half (see the drawing), the needle valve 31 is stopped lifting further, and the fuel is injected at a low rate of fuel injection. When the open/ close valve 65 opens the communicating hole 58 again, the fuel is discharged within the second volume part 61 through the communicating hole 58, thus increasing the lift amount of the needle valve 31, so that fuel injection can be carried out at a high rate of fuel injection.

Title: Loopback control system for loop transmission equipment
Inventor: NAKATANI TOSHIO
Filed: 1985-08-05
Abstract: PURPOSE:To prevent the whole system from breaking down even if disturbance is generated in a transmission line and to improve the working ratio of the system by storing loopback state in a loop back storing means. CONSTITUTION:Remote stations 2-6 are connected to a synchronizing station 1 through circular transmission lines 7, 8 which are circulated in the reverse directions to each other to transmit signals. When the lines 7, 8 are disconnected at points 9A, 9B, no input is applied to the station 1 and a supervisory control part 10 outputs a loopback command. Receiving the loopback command, the remote stations 3, 4 adjacent to the defective points form the loopback state and memories in the stations 3, 4 store the loopback state. When the lines 7, 8 in both the systems are restored, the supervisory control part 10 outputs a loopback release command and the remote stations 3, 4 release the loopback state. Consequently, the whole system can be prevented from malfunction due to disturbance at the restoration of the single system.
