  • Patent number: 11412607
    Abstract: An atomic beam generator includes a cathode constituted as a housing having an emission surface provided with an irradiation port through which an atomic beam is emissive; an anode disposed inside the cathode to generate plasma between the cathode and the anode; and a magnetic field generating unit including a first magnetic field generating unit that generates a first magnetic field and a second magnetic field generating unit that generates a second magnetic field, and guiding positive ions produced in the cathode to the emission surface by generating, in the cathode, the first magnetic field and the second magnetic field both parallel to the emission surface such that a magnetic field direction is leftward in the first magnetic field and is rightward in the second magnetic field when viewed from an emission surface side on condition of the first magnetic field being positioned above the second magnetic field.

  • Patent number: 9619007
    Abstract: An integrated circuit device includes first and second integrated circuits and a power supply line. The first integrated circuit includes a first power supply circuit, a timing generation circuit generating a synchronization signal, and a first power supply control section. The second integrated circuit includes a second power supply circuit and a second power supply control section. The power supply line electrically connects the outputs of the first and second power supply circuit. The first and second power supply control sections are each configured to start the operations of the first and second power supply circuits, respectively, in response to a start of a supply of the synchronization signal after a sleep-out command is supplied thereto. The timing generation circuit starts supplying the synchronization signal after a predetermined waiting time elapses after the sleep-out command is supplied to the first integrated circuit.
