Publication number: 20220067528Abstract: It is possible to construct an agent that can deal with even a complicated task. For a value function for obtaining a policy for an action of an agent that solves an overall task represented by a weighting sum of a plurality of part tasks, an overall value function is obtained, which is a weighting sum of a plurality of part value functions learned in advance to obtain a policy for an action of a part agent that solves the part tasks for each of the plurality of part tasks using a weight for each of the plurality of part tasks. The action of the agent corresponding to the overall task is determined using a policy obtained from the overall value function and the agent is caused to act.Type: ApplicationFiled: January 7, 2020Publication date: March 3, 2022Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Masahiro KOJIMA, Tatsushi MATSUBAYASHI, Hiroyuki TODA

Publication number: 20210107340Abstract: A protrusion is formed on a first part of an inner-cabin side wall of an installation base member of a protector with a sensor. The first part is closer to a connecting wall than a second part opposite the first part. The protrusion is on a virtual line in cross section. The virtual line is where convex substances, keys for example, hanging on passengers' clothes conceivably pass through. The virtual line extends toward a connecting point from a rear part of an automobile body closer to an interior of the automobile body than a reference line. The reference line is parallel with a direction in which a flange protrudes and extends from the connecting point. The connecting point is a part of an inner-cabin side end of a hollow part closest to an interior of the automobile body. The inner-cabin side end is connected with the installation base member.Type: ApplicationFiled: September 23, 2020Publication date: April 15, 2021Applicants: NISHIKAWA RUBBER CO., LTD., AISIN SEIKI KABUSHIKI KAISHAInventors: Hiroshi ISHIBASHI, Masahiro KOJIMA, Michihiko MATSUMOTO, Wataru HATTORI

Publication number: 20190234913Abstract: A main controller 201 of a main substrate 20 performs serial communications with a sub controller 214 of each flowrate control substrate 21. The flowrate of the carrier gas is controlled with the flowrate control circuit 213 under the control performed by each sub controller 214. Thus, the main controller 201 only needs to execute the processing of performing the serial communications with each sub controller 214. As a result, the processing executed by the main controller 201 can be reduced, and the processing executed by the main controller 201 is less likely to overwhelm its processing capability even when the number of flowrate control substrates 21 is increased. In addition, a signal line 40 between the main controller 201 and each sub controller 214 can be made long. Thus, the distance between the main substrate 20 and each of the flowrate control substrates 21 can be made long.Type: ApplicationFiled: September 8, 2016Publication date: August 1, 2019Applicant: SHIMADZU CORPORATIONInventor: Masahiro KOJIMA
