IPC: H04R9/02
Filed: 1991-09-27
Abstract: PURPOSE:To provide the electronic acoustic converter capable of driving two diaphragms with the same phase by utilizing a pair of magnetic circuits. CONSTITUTION:A conductor 27 on the surface of a magnet 25 is arranged on the position crossing the magnetic flux generated from the north pole to the south pole of a magnet 25. It is oscillated at right angles to the magnetic flux by the voice current flowing through this conductor 27. Thus the first diaphragm 26a on the surface is driven. The conductor 27 at the rear of the magnet 25 is arranged on the position crossing the magnetic flux generated from the north pole to the south pole of the magnet 25. It is oscillated at the right angles with the magnetic flux by the voice current flowing through this conductor 27, thus driving the second diaphragm at the rear in the same direction with the first diaphragm 26a. As this result, the first diaphragm 26a on the front and the second diaphragm at the rear are driven in the same phase, thus efficiently generating an acoustic signal using the same magnetic circuit.

Filed: 1987-11-04
Abstract: PURPOSE:To obtain a mark detection signal having no distortion by performing the reverse Fourier transformation of the output of a sensor array detector and finding the angle of incidence of a reflected signal to a detector, and correcting the phases of respective array sensors outputs. CONSTITUTION:An electron beam Bi illuminates a mark M added to a material 3. Consequently, the reflected signal Ri is radiated from the mark M. This signal Ri is inputted to the sensor array detector 11a. The detection signal of each detector 11a is added by adder 13. The output of the adder 13 is inputted to a reverse Fourier transformer 14 and processed by the reverse Fourier transformation to obtain each amplitude. An arithmetic circuit 15 finds the angle thetam of a signal (m) of an angle of incidence from the output of the transformer 14, and uses this nu to supply a correction quantity from the circuit 15 to a phase corrector 12. Consequently, signals passed through the corrector 12 are all uniform, so the output of the adder 13 has no distortion. For the purpose, the output of the adder 13 is supplied to a signal processing circuit. The other sensor array detector 11b, on the other hand, is also corrected similarly.
