The free end part of a fixed member 14 is inserted inside the cylinder part 13, while a magnet detector 8 is fitted to a side of said free end part. Since the magnet 7 is fitted in a position on the inner periphery of the cylinder part 13 formed in one body with the rotary shaft 6, even if big centrifugal force works on said magnet 7 due to high-speed rotation of the rotary shaft 6, said magnet 7 is pressed against the inner periphery of the cylinder part 13. Accordingly, centrifugal force working on a transmitter is received by the cylinder part itself, therefore, destruction and dispersion due to deterioration of the fitting part can be prevented beforehand.

Title: Spectrum analyzing method and spectrum analyzing device
Inventor: ODA HITOSHI
IPC: G01R23/16
Filed: 1986-11-27
Abstract: PURPOSE:To easily detect a high frequency component with high accuracy by detecting the radial variation of a cyclotron motion at the time when a microwave obtained from a signal to be measured has been radiated to an electron which is executing a cyclotron motion in a magnetic field. CONSTITUTION:An electron beam 21 emitted from a one-dimensional electron beam generating device 20 executes a cyclotron motion by an external magnetic field H, and reaches an electron beam detector 22. A pole piece of a magnet 25 is cut obliquely and the external magnetic field H has a prescribed gradient, therefore, frequencies of each beam 21-i are different. When a microwave 31 oscillated by a signal for analyzing a frequency is applied to a motion space of the beam 21, the prescribed beam 21 causes a resonance phenomenon, and the radius of the beam becomes large and the beam does not reach the detector 22. Accordingly, by detecting an output of each target of the detector 22, a frequency component of the microwave can be obtained.
