  • Publication number: 20160040751
    Abstract: An object of the present invention is to provide a silent chain transmission device which stabilizes chain behavior during chain travel to suppress an occurrence of tooth skipping and reduces a string vibration sound and a meshing noise with a simple configuration. In a silent chain transmission device 100 made up of a silent chain 110 and a sprocket 180, a pitch between rolling points I of locker pins 170 of front and rear pin holes 161 of a non-guide row 150 is set equal to a sprocket pitch S in a state where the silent chain 110 is wound around the sprocket 180 under a low load.

  • Publication number: 20160013012
    Abstract: A charged particle beam system has a charged particle beam source (110) for producing a charged particle beam (EB), a beam blanker (1) and a sample stage (130) on which a sample (S) is held. The sample (S) is irradiated with the beam (EB) passed through the beam blanker (1). The beam blanker (1) has a multistage deflector assembly (20) and a first apertured portion (30). Multiple stages of deflectors (20a, 20b, 20c) for deflecting the beam (EB) are arranged in the multistage deflector assembly (20). The first apertured portion (30) is disposed between the first stage of deflector (20a) and the second stage of deflector (20b) of the deflector assembly (20). The beam (EB) which has passed through the first aperture portion (30) after being deflected by the first stage of deflector (20a) is deflected back to an optical axis (OA) by the second and subsequent stages of deflectors (20a, 20b).

  • Patent number: 9051992
    Abstract: There is provided a silent chain that is reduced in weight and widthwise size by reducing the length of a short pin while preventing the occurrence of excessive stress concentration in the short pin of a rocker pin including a long pin and the short pin. The short pin of the rocker pin extends through all plates of the guide row and all plates of the non-guide row in the width direction. The short pin is provided with a first stopper, and a second stopper. A first end surface of the short pin is prevented from being positioned in a first adjacent pin hole by contact between the first stopper and the first contact portion, and a second end surface of the short pin is prevented from being positioned in a second adjacent pin hole by contact between the second stopper and the second contact portion.

  • Publication number: 20140367585
    Abstract: A method for axial alignment of a charged particle beam relative to at least three stages of multipole elements and a charged particle beam system capable of making the axial alignment. Some parts of the orbit of the beam or the distributions of three astigmatic fields, or both, are simultaneously translated in a direction perpendicular to the optical axis such that astigmatisms of the same order and same type due to axial deviations between successive ones of the astigmatic fields cancel.
