Publication number: 20240143989Abstract: A reservoir calculation device according to an embodiment includes a reservoir circuit and an output circuit. The reservoir circuit receives input data and outputs intermediate signals, each undergoing a transient change when the input data changes. The output circuit outputs an output signal obtained by combining the intermediate signals. The reservoir circuit includes intermediate circuits, each including a neuron circuit and an intermediate output circuit. The neuron circuit generates an intermediate voltage undergoing a transient change corresponding to weight data and the input data when the input data changes. The intermediate output circuit outputs an intermediate signal representing a level of the intermediate voltage from the neuron circuit. The neuron circuit includes a time constant circuit capable of changing a time constant. The time constant circuit is connected between a reference potential and an intermediate terminal outputting the intermediate voltage.Type: ApplicationFiled: August 27, 2023Publication date: May 2, 2024Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Takao MARUKAME, Kumiko NOMURA, Koichi MIZUSHIMA, Yoshifumi NISHI

Patent number: 4646293Abstract: A multiaccess communications system for a communications network in which a plurality of nodes are connected to a head end by a common transmission path to perform wideband transmission of packets between the nodes, particularly a multiaccess communications system such as a carrier sensing multiaccess (CSMA) system or a collision sensing CSMA (CSMA/CD) system. A single transmission cable or a pair of transmission cables are efficiently shared by various channels. Each of the nodes is provided with a transceiver in association with the cable or the cables. All the channels are effectively utilized by means of a relatively simple system construction.Type: GrantFiled: November 19, 1984Date of Patent: February 24, 1987Assignee: Ricoh Company, Ltd.Inventors: Hiromi Okada, Yoshiro Nakanishi, Yoshifumi Nomura
