Patent number: 11640895Abstract: 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.Type: GrantFiled: January 7, 2022Date of Patent: May 2, 2023Assignee: JEOL Ltd.Inventors: Shuichi Yuasa, Takahisa Kawamura

Patent number: 11631569Abstract: 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.Type: GrantFiled: January 7, 2022Date of Patent: April 18, 2023Assignee: JEOL Ltd.Inventor: Shuichi Yuasa

Publication number: 20210156457Abstract: An actuator has: a motor section; a ball spline having a finite stroke and equipped with a shaft capable of moving along its axis; an external screw thread formed on the shaft; a nut section having an internal screw thread engaging the external screw thread and operating to transmit the rotary force of the motor section to the shaft; and a case housing the motor section and the ball spline. The shaft has a contact section at its front end, the contact section being designed to make contact with the driven object. The contact section is lower than the shaft in thermal conductivity. Due to heat generated by the motor section, the shaft elongates along the axis of the shaft in a first direction, and the case elongates along the axis of the shaft in a second direction opposite to the first direction.Type: ApplicationFiled: November 23, 2020Publication date: May 27, 2021Inventors: Shuichi Yuasa, Masaaki Kobayashi, Yuta Ikeda
