Patent number: 10400820Abstract: In a linear motion guide unit, in order to prevent direct collision of a roller, or a rolling element, with an end portion of a carriage, an extending portion of a spacer of an end cap is disposed at the end portion of the carriage for absorbing impact resulting from collision of the roller. The spacer has the extending portion which protrudes from the spacer at a position adjacent to an inner circumferential surface of a turnaround passage and which has a wall surface continuous from the inner circumferential surface of the turnaround passage. The wall surface of the extending portion serves as a collision receiving surface for receiving a colliding roller. The carriage has a housing recess which is formed at an end of a raceway groove thereof and to which the extending portion is fitted.Type: GrantFiled: October 12, 2017Date of Patent: September 3, 2019Assignee: NIPPON THOMPSON CO., LTD.Inventor: Masaharu Yoshida

Patent number: 10294991Abstract: A linear motion guide unit prevents damage to a corner portion of an end surface of a carriage resulting from high-speed rolling of the rolling elements, and eliminates the need for strict dimensional management of facing end surfaces of the carriage and a spacer. A crowning is formed at an end portion of the carriage, and an R chamfered portion is formed at a corner of an end surface of the carriage. An R chamfered portion is formed at a corner of the end surface of the spacer. The R chamfered portions define a valley portion between the facing surfaces of the carriage and the spacer. The rolling elements roll above the valley portion while striding it to thereby be prevented from colliding against the corner portion of the end surface of the carriage, whereby damage to the corner portion of the end surface of the carriage can be prevented.Type: GrantFiled: February 23, 2018Date of Patent: May 21, 2019Assignee: NIPPON THOMPSON CO., LTD.Inventors: Kunihiko Kito, Kentaro Narita, Masaharu Yoshida

Patent number: 5774207Abstract: The present invention offers a light scanner which is compact and highly precise during high-speed operation, has a long lifespan, and is resistant to influence by external acceleration. Specifically, a light beam emitted from an optical source 20 is separated into two light beams by means of a light beam separation means 30, and these light beams are deflected by a mirror 43 on the scanner 40. On of the light beams is used for the object of usage, while the other light beam is made incident on a photo detector 50 which outputs a signal based on the incident position of the light beam, in order to determine the deflection angle of the light beam based on vibrations of the mirror 43.Type: GrantFiled: June 27, 1996Date of Patent: June 30, 1998Assignee: Nippon Telegraph and Telephone CorporationInventors: Masaharu Yoshida, Ken'ichi Arakawa, Kazuyoshi Tateishi
