  • Patent number: 5794603
    Abstract: An ignition coil device is provided in which a damaged portion can be exchanged and which requires no connector for connecting a power switch with a wiring harness. Since an ignition coil device 2 is constructed such that a primary coil portion 21 and a power switch 22 are secured by fitting the primary coil portion 21 into a hollow core of a secondary coil portion 23 mounted in advance on an engine 30, the primary and secondary coil portions 21, 23 can be detachably connected via an iron core 21c as a magnetic core. Accordingly, only the secondary coil portion 23 having a relatively short life due to the generation of varying high voltage can be easily exchanged. Further, since the power switch 22 and the primary coil portion 21 are integrally or unitarily connected with a wiring harness 40, the construction can be made inexpensive and simple by the deletion of a connector provided in a prior art ignition coil device, thereby enhancing electrical reliability.

  • Patent number: 4695724
    Abstract: A quadrupole mass spectrometer generates a stream of ionized particles which are modulated by an AC voltage and transmitted through a quadrupole analyzer to a detection unit. The detection unit detects at a collector electrode thereof a modulated ion current which is fed to a phase detector. The phase detector synchronizes the modulated ion current with a signal of known frequency to produce a DC voltage representative of the level of the modulated ion current. By modulating the ionized particles with the AC voltage, the S/N ratio is improved and adverse effects of external noise are diminished.
