Patent number: 12147374Abstract: A distributed control system includes a tree topology network or a daisy-chain network including a communication parent station, communication child stations, and a plurality of communication paths among the communication parent station and the communication child stations, in which the communication parent station and the communication child stations include a scheduling unit that controls a transfer cycle that is temporal intervals of data transfer. The scheduling unit sets the transfer cycle that is the fastest out of a plurality of the data as a reference cycle, counts the number of times each time the reference cycle elapses, and imparts a value of the number of times to the reference cycle as a cycle number. When the cycle number reaches an optional number, the number of times is returned to an initial value, which makes one cycle of transfer control, and the transfer control is repeatedly executed.Type: GrantFiled: June 11, 2020Date of Patent: November 19, 2024Assignee: Hitachi High-Tech CorporationInventors: Kazushi Yamashina, Takashi Saegusa, Yoshiro Gunji, Tetsuji Ohsawa, Yutaka Kasai, Junichi Kitamura, Naoya Ishigaki, Shusaku Maeda, Yoshikuni Yokose

Patent number: 12093807Abstract: A neural network not requiring massive changes in configuration when changing the number of stages (number of levels) of the neural network. This neural network is provided with at least one neuron core 10 performing an analog multiply-accumulate operation and a weight-value-supply control unit 30 supplying the weight value to the neuron core 10. This neural network is subjected to control processing by a control-processor unit 40 controlling the supply of the weight value from said weight-value-supply control unit 30 in synchronization with the timing of the analog multiply-accumulate operation of the neuron core 10, and processing the data output from the neuron core 10 at every analog multiply-accumulate operation performed by said neuron core as serial data and/or parallel data.Type: GrantFiled: June 3, 2020Date of Patent: September 17, 2024Assignees: Kabushikiki Kaisha Toshiba, Toshiba Information Systems (Japan) CorporationInventors: Takao Marukame, Kazuo Ishikawa, Junichi Sugino, Toshimitsu Kitamura, Yutaka Tamura, Koji Takahashi

Patent number: 6082086Abstract: A reel-type cutting unit including a reel blade for cutting grass in cooperation with a fixed blade. The reel blade is rotatable about a horizontal axis extending transversely of a vehicle body, to move from front to rear relative to the fixed blade with respect to a forward traveling direction of the vehicle body. The cutting unit has a main case surrounding the reel blade to define a space for carrying grass clippings in a rotating direction of the reel blade to a top level of the reel blade. A guide member is connected to the main case for receiving the grass clippings carried to the top level. The guide member defines a grass receiving space having a grass discharge opening. The grass discharge opening is connected to a grass catcher through a duct.Type: GrantFiled: April 17, 1998Date of Patent: July 4, 2000Assignee: Kubota CorporationInventors: Yoshikazu Togoshi, Yoshiyuki Esaki, Yoshihiro Kawahara, Teruo Shimamura, Junichi Kitamura, Osami Fujiwara, Hideya Umemoto, Koji Fujiwara
