  • Publication number: 20250108426
    Abstract: To provide a trimming device with which it is possible to suppress the deterioration of shape quality after trimming a cylindrical workpiece. When trimming is performed by means of a core metal cutting edge 33f and a tool cutting edge 31f upon moving at least one of a core metal punch 33 and a trimming tool 31A, gaps H1, H2 are formed between the core metal punch 33 and a workpiece W. Damper mechanisms 100A, 100B are arranged in the gaps H1, H2. The damper mechanisms 100A, 100B are arranged so as to abut on the workpiece W when trimming is performed by the core metal cutting edge 33f and the tool cutting edge 31f, and are constituted so as to elastically deform when a force acts in a direction in which the trimming tool 31A moves forward and backward.

  • Patent number: 7005634
    Abstract: An ionization apparatus according to the present invention has a mechanism for causing metal ions emitted from an ion emitter to attach to an introduced target gas so as to generate ions of the sample gas and emits the ions of the sample gas to a mass spectrometer. The mass spectrometer has a zone in which one or both of an electric field and magnetic field are formed. As the electrode for causing the generation of cleaning plasma in the ionization zone generating the ions of the sample gas, the ion emitter is used. The ion emitter causes the generation of plasma in connection with a hollow vessel and removes deposits on components facing the ionization zone by the plasma. The plasma cleaning process is performed consecutively at a suitable timing after the ionization process. Due to the above configuration, deteriorated performance in ionization can be restored in a short time, a memory effect can be prevented, and accurate mass spectrometry becomes possible.
