Abstract: PROBLEM TO BE SOLVED: To enable simultaneous discrimination of a plurality of frequency signals without being affected by cross modulation, by detecting an electric field generated in a conductor element by an electric signal, with a plurality of probes, converting the detected values into data containing amplitudes and phases, and analyzing the data. SOLUTION: An input signal containing a plurality of frequency components is inputted in a conductor element 4 of linear conductor, and a current distribution is constructed in the element 4. The distribution is picked up with a plurality of probes 5 which are arranged along the element 4 at fine intervals. The phase/amplitude information of the signal is detected with an I/O detector, and sent to a signal analyzer 7. In the case of high frequency measurement, the interval between the probes 5 is reduced, and the element 4 having an electric length corresponding to the range of frequency is used. The analyzer 7 converts the information from a signal detector 3 into digital data with an A/D converter 8, and analyzes the frequency component and the amplitude, with an operating equipment 9. Thereby cross modulation due to frequency conversion is prevented, and a plurality of frequencies which are simultaneously inputted can be analyzed.

Abstract: PROBLEM TO BE SOLVED: To improve adhesion by forming a land having a height not less than that of a wiring pattern at a slightly wide area from a mounting region to block adhesives from extruding at the time of compression bonding of a chip. SOLUTION: A land 4D forming a part of the wiring pattern on a board 4A is formed in an area, slightly larger than the projection area of a chip on the board 4A. When the chip 5A is compressively bonded through an anisotropically conductive adhesive 6A on a wiring pattern 4C, the adhesive 6A extrudes from the periphery of the mounting area due to the heat and pressure applied to the chip 5A, but is blocked by the land 4D having a thickness not less than that of wiring patterns 4a, 42 on the board 4A, resulting in the deposit of the adhesive to the outer wall of the chip 5A. This increases the adhesion area of the anisotropically conductive adhesive 6A and improves the adhesion.

Abstract: PURPOSE:To prevent the generation of unstable condition by slowing down the moving speed of a plunger and vibrating it at center position by providing the guide pipe made of non-magnetic and conductive material on the periphery of the plunger. CONSTITUTION:When the excitation of a coil 1c is released, the magnetic flux flowing in a plunger 3 declines rapidly from the magnetic flux (phi2+phi3) which is compounded by those of the coil 1c and a permanent magnet 8 to the magnetic flux phi2 only of the permanent magnet 8 and the return force of a right-side return spring 5 is applied to the plunger 3 intensively. Then the static condition in a neutral position becomes unstable. However, by the help of the conductive guide pipe 2 provided on the periphery of the plunger 3, the induced current generated in the direction for preventing the change of the magnetic flux, and the magnetic flux phi2 of the coil 1c does not rapidly decrease, but decreases at a certain time constant. Accordingly, the right-side return spring 5 does not apply an intensive force to the plunger 3 and moves the plunger to the neutral position smoothly.
