Patent number: 9199826Abstract: An article transport facility in which reduction in the transport capacity can be prevented while simplifying the structure and making the facility less expensive is provided. The facility includes, as travel paths, a first travel path and a second travel path which straddles the first travel path from one side to the other side in a lateral direction of the first travel path. In a straddling portion, which is a part of the second travel path that straddles the first travel path, the second travel path is provided at a different height from the first travel path in a vertical direction, and is configured such that travel of the article transport vehicle along the first travel path and travel of the article transport vehicle along the second travel path are mutually allowed.Type: GrantFiled: June 17, 2011Date of Patent: December 1, 2015Assignee: Daifuku Co., Ltd.Inventors: Suguru Shibata, Daisuke Ogawa, Yoshitaka Inui

Patent number: 9097847Abstract: A Raman scattered light enhancement device including a waveguide provided in a photonic crystal (20) made of a semiconductor substrate in which holes (20a) are formed. The waveguide has resonant modes with respect to incident light at a plurality of frequencies. A difference in frequency between one resonant mode and another resonant mode is equal to a Raman shift frequency of the semiconductor substrate. A waveguide forming direction with respect to a crystal plane orientation of the semiconductor substrate is set so as to maximize a Raman transition probability which is represented by electromagnetic field distribution of the two resonant modes and a Raman tensor of the semiconductor substrate.Type: GrantFiled: March 8, 2013Date of Patent: August 4, 2015Assignee: Japan Science and Technology AgencyInventors: Yasushi Takahashi, Yoshitaka Inui, Takashi Asano, Susumu Noda, Masahiro Chihara
