Publication number: 20240126952Abstract: In an arithmetic operation system, an evaluation unit calculates a difference amount between a teaching signal and an estimated signal. The teaching signal is a spatial distribution signal observed with respect to a spatial structure on a path of an emission wave in a target space (i.e., a teaching space) by using the emission wave. In addition, the estimated signal is a signal for comparing with the teaching signal, and is an estimated spatial distribution signal. The estimated signal is formed based on estimated density associated to each sample point acquired from a spatial estimation model, by a sampling unit inputting information about a position of each of a plurality of sample points on the path to the spatial estimation model. An updating unit updates the spatial estimation model, based on the difference amount.Type: ApplicationFiled: October 2, 2023Publication date: April 18, 2024Applicant: NEC CorporationInventors: Tsubasa NAKAMURA, Jiro ABE

Patent number: 8084003Abstract: A vessel (102) containing a detector solution (101) is prepared. The detector solution (101) is an aqueous solution prepared by dissolving a detector component containing a dye which changes its color when reacting with ozone gas, a humectant, and an ultraviolet absorber having a hydrophilic group. A prepared sheet-like carrier (103) is dipped in the detector solution (101) for, e.g., 30 sec, thereby forming an impregnated sheet (104) by impregnating the sheet-like carrier (103) with the detector solution (101). The impregnated sheet (104) is then dried by evaporating the solvent (medium) such as water contained in the impregnated sheet (104), thereby forming a sheet-like ozone detecting device (105).Type: GrantFiled: October 17, 2007Date of Patent: December 27, 2011Assignee: Nippon Telegraph and Telephone CorporationInventors: Takashi Miwa, Yasuko Maruo, Jiro Nakamura, Tatsuya Kunioka, Seizo Sakata

Patent number: 7976781Abstract: An aqueous solution is formed by dissolving a dye made of alizarin and a humectant made of glycerin, and alkalized by dissolving a base (alkaline substance), thereby preparing a detector solution (101) in which the content of the humectant is about 20 wt %. An impregnated carrier (104) impregnated with the detector solution (101) is formed by dipping for 30 sec a sheet-like carrier (103) made of cellulose filter paper in the detector solution (101) so that the carrier (103) is impregnated with the detector solution (101). The impregnated carrier (104) is pulled up from the detector solution (101), and dried in dry nitrogen by evaporating a solvent such as water contained in the impregnated carrier (104), thereby forming an ozone detecting device (105).Type: GrantFiled: October 2, 2007Date of Patent: July 12, 2011Assignee: Nippon Telegraph and Telephone CorporationInventors: Yasuko Maruo, Takashi Miwa, Jiro Nakamura, Tatsuya Kunioka

Patent number: 7484616Abstract: A transportation facility in which an object transported while being suspended from a hanger such as a trolley conveyor is transferred on to a carriage of a carriage-type transportation device for a certain section of a route. At the start point, there is an object receiving means at the under side of a traveling route of a traveling body. An object support device is lifted relative to the hanger of the traveling body and the object receiving means is caused to receive the object (W) from the hanger. At the end of the transportation, an object return means is provided for lowering the object support device relative to the hanger to transfer the object to the hanger. In the transportation route, the traveling body is switched to a state in which drive is released and a hanger engagement means is engaged with the hanger so that the traveling body can be pulled and moved by the carriage.Type: GrantFiled: December 18, 2007Date of Patent: February 3, 2009Assignee: Daifuku Co., Ltd.Inventor: Jiro Nakamura

Patent number: 5966923Abstract: A conventional chain capable of reserving lubricating oil is complex in shape and expensive since each chain plate is formed with countersunk recesses and through-openings. Since the recesses are formed in an overlap region, the chain tends to rattle, producing noise. In the present invention according to which lubricating oil is fed toward a connecting pin, the lubricating oil is transferred to the connecting pin to effect intended lubrication. Part of the lubricating oil thus fed adheres to the recessed surfaces of the recesses and is prevented from immediately flowing down by viscous friction resistance and surface tension in the recessed surfaces. Thus, the oil is held in its adhering state. The lubricating oil gradually flows down to be used for lubrication as the chain moves. Thereby, after the chain has passed by an oil feeder, the connecting pin of the chain stays in such a state that oil is fed continuously for a long time.Type: GrantFiled: February 16, 1999Date of Patent: October 19, 1999Assignee: Daifuku Co., Ltd.Inventor: Jiro Nakamura
