Patent number: 10360315Abstract: The object is to enable easy acquisition of an element that is not design data. The technique is characterized in that when generating construction field management information used to manage a construction field, a construction field management device acquires measurement data that is three-dimensional shape data measured by a measurement device, and compares design data created by a designer with the acquired measurement data, thus extracting non-design data that is not the design data, from the measurement data.

Publication number: 20180128716Abstract: Minute particles in a gas generated in a particle generating unit are charged by a charging unit. A concentrating unit concentrates charged particles in an introduced gas, and a collecting unit absorbs and collects the concentrated charged particles on a sample plate by an electrostatic force. In the concentrating unit, the charged particles are concentrated by decreasing a flow rate of a gas (carrier gas) in which particles are dispersed while maintaining the number of introduced charged particles. When the flow rate of the gas decreases, and spatial density of the particles increases, it is possible to efficiently collect charged particles on the small sample plate in the collecting unit, and to shorten a collection time.Type: ApplicationFiled: November 9, 2017Publication date: May 10, 2018Applicant: Shimadzu CorporationInventors: Hiroshi Seki, Yoshihiro Ueno, Hiroshi Okuda, Hiromu Sakurai

Publication number: 20180071750Abstract: A gas stream containing charged particles is introduced through a first gas inlet port into a first space, while another gas stream containing charged particles is introduced through a second gas inlet port into a second space located below and separated from the first space by a mesh-like filter. Voltages are respectively applied to an upper plate electrode, lower plate electrode 16 and filter to create a DC electric field within a housing. Due to this electric field, the charged particles contained in the gas stream flowing in the first space move toward the second space.
