Title: Multiplexer
Inventor: LAUDE JEAN-PIERRE
IPC: G02B6/34
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To obtain a small-sized multiplexer having better characteristics and lower crosstalks by providing an optical coupling means with a reflection means which enables a large Littrow angle and assures the turn back of an optical axis. SOLUTION: An incident fiber 2 and exit fiber 3 are arranged at their respective ends at the focus of a spherical mirror 4. Then, the luminous flux radiated by the incident fiber 2 is converted to parallel luminous fluxes by this mirror 4. These parallel luminous fluxes are reflected by a mirror 8 inclined at an angle a with a luminous flux incident-exit axis 10. The parallel beams are thus reflected as the parallel secondary beams having an axis 12 by the mirror 8. A diffraction grating 7 disposed at a grating supporting body 9 is applied to one of the plane flanks 13 of a branching filter and the normal of the grating plane is included in the plane formed by the incident-exit axis 10 and the normal of the mirror 8. The secondary beam 12 forms an angle β (Littrow angle) with the normal of the grating.  The relatively large angle β is obtd. by turning back the parallel light beams.

Abstract: PURPOSE:To insert a pseudo vertical synchronizing signal into a reproducing video signal without annihilating a pulse of a 1/2 horizontal period by separating the pulse contained by the pseudo vertical synchronizing signal from the signal and making a clamp means in a non-operating condition in the period of the pulse. CONSTITUTION:When a pseudo vertical synchronizing signal PVS is supplied to a terminal 22, a switch circuit 8 is switched to a terminal B side and a pulse 600' of a 1/2 H is supplied from a waveform shaping circuit 17. While this pulse 600' is generated, a comparator 11 is in the non-operating condition and during the neighboring pulse 600', the comparator 11 is in an operating condition. As a result. the pulse 600' of the 1/2 H is inserted into a pseudo vertical synchronizing signal part in the reproducing video signal and the voltage of the part except the pulse 600' is clamped to a reference voltage VC. Consequently, the horizontal AFC circuit of a television receiver 21 can executes a horizontal AFC action even in a pseudo vertical synchronizing period.

Abstract: PURPOSE:To detect the abnormal vibration of a turbine shaft and to enable an alarm to be produced for informing of cracks by a method wherein a rotary synchronizing vibration and a rotary synchronizing double vibraion component are extracted from the vibration of the turbine shaft and compared to each other, and the compared value is further compared with a total amplitude. CONSTITUTION:A vibration sensor 11 transduces the sensed vibration of a turbine shaft 8 to an electrical signal. A full amplitude calculater 13 calculates a full amplitude value of vibration. A synchronized vibration calculater 14 separates the vibration value of a rotating synchronizing vibration component as VOMEGA. The synchronizing double vibration calculater 15 separates a vibration value of the rotating synchronizing double vibration component as Z2OMEGA. A comparater calculater 17 compares all the amplitudes from the full amplitude calculater 13 with a value of V2OMEGA/VOMEGA from the divider 16, and when both values exceed the prescribed relation, an alarm signal is produced. In this way, some cracks in the turbine shaft 8 can properly be detected.
