Publication number: 20240404284Abstract: An acquisition unit (30) acquires, for a work including a plurality of steps, a material feature quantity representing each material used in the task, and a video feature quantity extracted from each clip, which is a video of each step in which the task is captured. An updating unit (40) identifies an action for a material included in the clip based on the video feature quantity of each clip, and updates the material feature quantity of the identified material in accordance with the identified action. A generation unit (50) generates a sentence explaining a task procedure for each of the steps based on the updated material feature quantity, the specified action, and the video feature quantity.Type: ApplicationFiled: September 21, 2022Publication date: December 5, 2024Applicants: OMRON Corporation, KYOTO UNIVERSITYInventors: Atsushi HASHIMOTO, Yoshitaka USHIKU, Shinsuke MORI, Hirotaka KAMEKO, Taichi NISHIMURA

Publication number: 20230013870Abstract: Accuracy of a model extracting a graph structure as an intermediate representation from input data is improved. An encoding unit (100) extracts a feature amount of each of a plurality of vertices included in a graph structure (Tr) from input data (10), and calculates a likelihood that an edge is connected to the vertex. A sampling unit (130) determines the graph structure (Tr) based on a conversion result of a Gumbel-Softmax function for the likelihood. A learning unit (150) optimizes a decoding unit (140) and the encoding unit (100) by back propagation using a loss function including an error (LP) between output data (20) generated from the graph structure (Tr) and correct data.Type: ApplicationFiled: February 19, 2021Publication date: January 19, 2023Applicants: OMRON CORPORATION, KYOTO UNIVERSITYInventors: Atsushi HASHIMOTO, Yoshitaka USHIKU, Shinsuke MORI, Taichi NISHIMURA

Publication number: 20220313002Abstract: Disclosed is a roaster/roasting machine for roasting an edible plant such as coffee beans. This roaster/roasting machine comprises a roasting chamber for containing a substance to be roasted, the roasting chamber being made of a carbon material (graphite, CC composite, etc.). Thus, the roaster/roasting machine can utilize far-infrared rays for roasting with a simple structure. A roaster comprising an open top container body and a closure member may be used for home roasting. A roasting machine comprising a drum-shaped roasting chamber may be a professional roasting machine. The present invention can be applied to any of a direct-, semi-hot air-, and hot air-heating type roaster/roasting machine. Also disclosed is a method for roasting beans such as coffee beans, the method comprising contacting beans with a heated graphite.Type: ApplicationFiled: December 8, 2020Publication date: October 6, 2022Applicant: ANAORI CARBON CO., LTD.Inventors: Ryuichi NISHIDA, Yoshimi NISHIDA, Eiichi ANAORI, Taichi NISHIMURA, Toshiaki SOGABE, Kenji INUKAI, Hironori KANZAKI, Shusuke HIROBE, Noriaki KATO, Chiho ANAORI

Publication number: 20130174811Abstract: A temperature reduction control for reducing the temperature of an injector is performed through first to third fuel supply control routines executed by an electronic control device. When the temperature of the injector is reduced by the execution of the temperature reduction control, heat transfer to the vicinity of the nozzle of the injector is reduced. Since the vicinity of the nozzle of the injector is less likely to be placed in a high-temperature environment by in accordance with reduction in heat transfer to the vicinity of the nozzle of the injector, the formation of deposit around the nozzle of the injector is suppressed.Type: ApplicationFiled: April 20, 2011Publication date: July 11, 2013Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Taichi Nishimura, Rihito Kaneko
