Patent number: 11644325Abstract: Based on schedule information indicating one or more events to be occurred and information relating to a location associated with each of the one or more events, a navigation method estimates an area and time at which congestion may be likely to occur in the vicinity of the location. Furthermore, the navigation method presents to a moving body information which is based on the estimated result of the area and the time, and which is related to a movement plan when moving using the moving body.Type: GrantFiled: January 28, 2019Date of Patent: May 9, 2023Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Hiroyuki Uematsu, Hiroyuki Sasai, Takeshi Ando, Noriaki Imaoka, Duyhinh Nguyen

Publication number: 20220043461Abstract: A platoon travel system that allows a plurality of moving objects to perform a platoon travel includes a plurality of moving objects capable of performing a pivot turn and a control device that controls travels of the plurality of moving objects. When stopping a platoon of the plurality of moving objects, the control device stops each of the moving objects in a state where each of the plurality of moving objects has a predetermined inter-moving-object distance from an adjacent moving object among the plurality of moving objects. The predetermined inter-moving-object distance is a distance allowing the moving object to perform a pivot turn of 180 degrees.Type: ApplicationFiled: July 13, 2021Publication date: February 10, 2022Inventors: DUYHINH NGUYEN, HIROYUKI SASAI

Patent number: 10900832Abstract: An irradiation region 21 of a diffraction grating 2 includes a first irradiation region (21A) and a second irradiation region (21B). In the diffraction grating 2, a blaze wavelength of a groove 22 of the first irradiation region (21A) is different from a blaze wavelength of a groove 23 of the second irradiation region (21B). That is, the first irradiation region (21A) and the second irradiation region (21B) have different relationships between a wavelength of light to be spectrally dispersed and a diffraction efficiency. Therefore, in a spectral device, light on a short wavelength side of light reflected by the second irradiation region (21B) of the diffraction grating 2 is not diffracted and is not received by a detector. Then, in a spectral device 1, aberration on the short wavelength side is corrected.Type: GrantFiled: June 6, 2016Date of Patent: January 26, 2021Assignee: Shimadzu CorporationInventor: Hiroyuki Sasai

Patent number: 10338285Abstract: An object is to provide a blazed diffraction grating having a smaller blaze angle than an existing blaze angle, and a method for producing the same. A method for producing a blazed diffraction grating includes the steps of forming a resin layer on a support having a saw-tooth sectional shape and having a surface on which a basic blaze surface and a basic riser surface are arranged alternately and repeatedly in a direction, such that the thickness of the resin layer contacting with the surface monotonically changes in the direction, and forming a metal coating film covering the resin layer surface. The method for monotonically changes the thickness comes in a formation method by difference in volatilization volume after applying a solvent resin on the support, and a formation method by a centrifugal force.Type: GrantFiled: October 7, 2013Date of Patent: July 2, 2019Assignee: Shimadzu CorporationInventor: Hiroyuki Sasai
