Abstract: An actuator capable of reducing vibrations of its output shaft is offered. The actuator (100) includes an electric motor (10), a ball spline (20) of finite stroke length, and a nut (32). The ball spline (20) has a shaft (22) provided with rolling grooves (23) which are formed along the axis of the spline and along which balls (24) can roll. An external thread (34) is formed on the shaft (22). The nut (32) has an internal thread (33) with which the external thread (34) threadedly mates, and operates to transmit the rotary force of the motor (10) into the shaft (22).

Abstract: There is provided a sample holder which is for use in a charged particle beam system and which can prevent damage to a sample stage during transportation of a cartridge. The sample holder includes: the cartridge having the sample stage for holding a sample therein; and a holder base having a mounting portion to which the cartridge can be mounted. The cartridge has: a tilt mechanism for tilting the sample stage; and a lock lever which, when the cartridge has been taken out from the mounting portion, makes contact with the sample stage and limits tilt of the stage.

Abstract: Provided is a charged particle beam system capable of reducing the force applied to a sample when a chuck device grips the sample. The charged particle beam system is typified by an electron microscope including a sample chamber, a sample exchange chamber connected to the sample chamber, a sample container capable of being removably attached in the sample exchange chamber, and a transport device for transporting the sample between the sample container and the sample exchange chamber. The transport device includes the chuck device for gripping the sample, a drive mechanism for moving the chuck device in a given direction, a mechanical driver for actuating the chuck device, and a power transmission mechanism for transmitting power of the mechanical driver to the chuck device. The power transmission mechanism includes a shaft and a resilient member that elastically deforms when a force in the given direction is applied to the shaft.

Abstract: There is provided a sample holder capable of reducing positional deviation of a cartridge in the heightwise direction of a sample. The sample holder includes the cartridge and a holder base having a mounting portion for the cartridge. The mounting portion includes a placement surface, a first tilted surface, and a rotary drive mechanism for imparting a rotary force to the cartridge. The cartridge includes an opposing first tilted surface opposite to the first tilted surface of the mounting portion. As the rotary drive mechanism imparts the rotary force to the cartridge, the first tilted surface of the cartridge is pressed against the first tilted surface of the mounting portion, whereby the cartridge is pressed against the placement surface.
