PURPOSE:To separate a pilot signal securely from an audio signal without influencing the audio signal, by recording the single pilot signal on more than one audio track in an inphase or out-of-phase state in accordance with the kind of a multiple audio signal. CONSTITUTION:A signal obtained by demodulating a multiple audio signal is recorded on more than one audio track, and in accordance with the kind of the multiple audio signal, a single pilot signal is recorded on more than one audio track in an inphase or out-of-phase state. For example, the recording system 10A of a VTR superposes on encoded single-frequency pilot signals Pb and Pc, generated by a generating circuit 20 from the output Pw of a detecting circuit 15 for the multiple control signal, corresponding to the multiple control signal on demodulated audio signals Sb and Sc to record them on audio tracks of a magnetic tape 5. A reproduction system 10B supplies a reproduced control signal Pw' to a generating circuit 40 for the multiple control signal CS, which is generated corresponding to the pilot signals Pb and Pc.

Abstract:
PROBLEM TO BE SOLVED: To provide a micro resonator which secures frequency characteristics, by controlling the fluctuations in the center frequencies among each resonator element. SOLUTION: A micro resonator structural body 10 is constituted so as to be simultaneously provided with a resonator element structural body 11, having a plurality of resonator elements F and contributing to a resonance operation and with a non-resonator element structural body 12, arranged at a periphery of the resonator element structural body 11 having a plurality of non-resonator elements N and giving no contribution to the resonance operation. Even though the micro resonator structural body 10 is influenced by a reflective light at processing a photolithography in its manufacturing process, a forming accuracy of the resonator elements F is secured; while the forming accuracy of the non-resonator elements N is reduced since the influence of the reflected light is easily brought to the forming accuracy of the eternal non-resonator elements N, while it is less likely to affect the forming accuracy of the central resonator elements F. Since the formed dimension of each resonator element F will thereby not easily fluctuate, the center frequency among each resonator element F will not easily fluctuate. COPYRIGHT: (C)2006,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a manufacturing method of a micro machine, forming a movable part with good pattern accuracy without a special manufacturing apparatus. SOLUTION: In the state of covering a sacrificial layer 8 formed in a pattern on a substrate 8, an insulating structure film 11 and a conductive film 13 are formed in order. With a first resist pattern 201 used as a mask, a conductive film 13 part on a sacrificial layer 9 is etched according to the shape of the movable part. After the first resist pattern 201 is removed and the surface of the conductive film 13 is subjected to corrosive processing, with the conductive film 13 used as a mask, the structure film 11 part on the sacrificial layer 9 is etched according to the shape of the movable part to expose part of the sacrificial layer 9. With a second resist pattern 203 for covering the upper side of the sacrificial layer 9 as a mask, the conductive film 13 part on the structure film 11 is etched according to the shape of a wiring pattern 13a. After the second resist pattern 203 is removed, the sacrificial layer 9 is selectively removed to form a space part (a) below the movable part 15. COPYRIGHT: (C)2005,JPO&NCIPI
