Autor: Yuuma TAMARU, Hiroki SHIMIZU
Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 83, Iss 854, Pp 17-00278-17-00278 (2017)
Non-contact supports involving air or magnetic forces are used as guide supports for linear motion mechanisms. In the present study, non-contact supports are generated using the effect of the static pressure force produced by a squeezed air film. The

Correction of positioning and angular errors for ball screw feed unit
Autor: Yuuma TAMARU, Hiroki SHIMIZU, Hiroshi KAMODA
Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 80, Iss 816, Pp DR0240-DR0240 (2014)
In the present study, we developed a new feed correction mechanism which corrected not only a positioning error (i.e., feed deviation) but also an angular error (i.e., yaw of a table). A correction mechanism including two piezoelectric actuators was

Square Layout Four-Point Method for Two-Dimensional Profile Measurement and Self-Calibration Method of Zero-Adjustment Error
Autor: Ryousuke Yamashita, Takuya Hashiguchi, Tasuku Miyata, Yuuma Tamaru, Hiroki Shimizu
Publikováno v: International Journal of Automation Technology. 12:707-713
An on-machine measurement method, called the square-layout four-point (SLFP) method with angle compensation, for evaluating two-dimensional (2-D) profiles of flat machined surfaces is proposed. In this method, four displacement sensors are arranged i

A Novel MEMS Device for Scanning Profile Measurement with Three Cantilever Displacement Sensors
Autor: Shinya Yanagihara, Yuuma Tamaru, Hiroki Shimizu, Takahiro Akiyoshi, Akiyoshi Baba
Publikováno v: Applied Mechanics and Materials. 870:237-242
A novel Micro Electro Mechanical System (MEMS) measurement device for straightness measurement with a three point method has been proposed. This device integrates three cantilever displacement sensors with a narrow pitch on a silicon chip. The author

Property Evaluation of Eccentric Astigmatic Method to Apply Micro Tactile Probe
Autor: Yoshinori Sasaki, Atsuo Ogawa, Hiroki Shimizu, Yuuma Tamaru
Publikováno v: International Journal of Automation Technology. 9:551-557
Displacement detection of a small sphere with high sensitivity is required for realizing the micro tactile probe used in micro-coordinate-measuring machines (CMMs). Therefore, the authors have proposed a new technique for detecting the three-dimensio

Development of a Compact Deformable Mirror Using Push-Pull Actuators
Autor: Hiroki Shimizu, Yuuma Tamaru, Keitaro Tanaka
Publikováno v: Key Engineering Materials. 613:200-203
A small deformable mirror which realizes concave shape as well as convex shape has been developed. In addition, this deformable mirror was developed to realize long term stability. For this purpose, a new push-pull actuator using two multilayered pie
