  • Patent number: 11119121
    Abstract: Provided is a probe pin alignment device that can readily correct a positional deviation between a probe pin and an electrode pad in real time and can prevent damage to the probe pin or an electronic device. The probe pin alignment device includes a mirror to reflect a mirror image of the electrode pad while the probe pin is approaching a crystal oscillator, a camera to take a picture containing an image of the probe pin and the mirror image reflected on the mirror, a deviation measurer to measure a deviation between the position of the probe pin and the position of the electrode pad in the taken picture, a displacer to relatively displace a carrier and the probe pin, and a controller to cause the displacer to relatively displace the carrier and the probe pin such that the deviation is substantially zero.

  • Patent number: 7806985
    Abstract: An improvement has been made in contact states between a rotating electrode arranged inside a vacuum chamber and a power supply mechanism which touches the rotating electrode to supply electric power thereto. A vacuum device is provided with a vacuum chamber, a rotating electrode arranged inside and electrically insulated from the vacuum chamber, and a power supply mechanism which touches the rotating electrode to supply electric power thereto, wherein the rotating electrode has an annular shape and horizontally rotates with respect to the center axis of the annular shape, and the power supply mechanism is composed of electrode members, and the electrode member and the rotating electrode come into contact with each other at at least one contact surface.

  • Patent number: 7626180
    Abstract: An ion gun 11 supplies an Ar gas into a main body 111 from a gas inlet 114, causes DC hot cathode discharge between a filament 113 and an anode 112 to generate Ar plasma. Next, a voltage gradient is applied to separated accelerator grids 116a, 116b having a bi-separated configuration in an ion ejecting direction. The each potential of the separated accelerator grids 116a, 116b is independently controlled by independently setting accelerator control switches 121a, 121b on or off to change the potential of that of the separated accelerator grids 116a, 116b which corresponds to an ion beam to be disabled.

  • Patent number: 6773557
    Abstract: System for frequency adjustment of piezoelectric resonators by ion etching in vacuum, based on arranging the resonators in rows and columns on a tray that can be moved to simultaneously expose two rows of resonators to the two straight-track portions of an ion gun having a race-track-shaped beam pattern whose straight tracks are spaced at an integer multiple of the inter-row spacing d. As the tray is moved in steps of d, two rows can be etched simultaneously, and each row can be sequentially exposed to a “pre-etch” and “final-etch” stage, with time between the two stages for the resonators to cool down after the “pre-etch” stage.
