Publication number: 20230315673Abstract: 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: ApplicationFiled: June 11, 2020Publication date: October 5, 2023Applicant: Hitachi High-Tech CorporationInventors: Kazushi YAMASHINA, Takashi SAEGUSA, Yoshiro GUNJI, Tetsuji OHSAWA, Yutaka KASAI, Junichi KITAMURA, Naoya ISHIGAKI, Shusaku MAEDA, Yoshikuni YOKOSE

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

Patent number: 5337543Abstract: A lawn mower for use both as walking operator type and riding type, having a grass cutting unit, an engine located rearwardly thereof, a driver's seat located above the engine, a floor step located over the grass cutting unit to be movable between an open position and a closed position, and right and left rear wheels driven by the engine. The rear wheels have respective stepless transmissions operable independently of each other to transmit engine drive in different speeds to the rear wheels. These transmissions are operable by shift levers located on opposite sides of the driver's seat when the lawn mower is used as the riding type, and by control levers extending rearwardly of the driver's seat when the lawn mower is used as the walking operator type.Type: GrantFiled: April 27, 1992Date of Patent: August 16, 1994Assignee: Kubota CorporationInventors: Junichi Kitamura, Hirofumi Sadakane, Yoshio Tomiyama

Patent number: 5307612Abstract: A lawn mower for use in a walking mode and a riding mode, having a chassis frame, an engine mounted on a rearward position of the chassis frame, front wheels, driven rear wheels, transmissions for transmitting drive from the engine to the rear wheels after varying speed of the drive, a grass cutting unit suspended from the chassis frame, a driver's seat mounted on the chassis frame, and a handle post supporting control levers for controlling the transmissions. The handle post is pivotable between a first position for the walking mode in which the control levers are disposed rearwardly of the chassis frame, and a second position for the riding mode in which the control levers are disposed adjacent the driver's seat. The handle post includes a vertical post portion extending laterally of the lawn mower, and a horizontal post portion curved from the vertical post portion to extend transversely of the lawn mower. The control levers are provided on the horizontal post portion.Type: GrantFiled: March 12, 1993Date of Patent: May 3, 1994Assignee: Kubota CorporationInventors: Yoshio Tomiyama, Junichi Kitamura

Patent number: 5247784Abstract: A walking operator type lawn mower having stepless transmissions allocated to right and left rear wheels for changing speed of engine drive and outputting the drive to the right and left rear wheels, respectively, whereby the right and left rear wheels may be driven at different speeds. Right and left control members operable by a speed control lever frictionally fixable to a selected position are interlocked to change speed arms through springs, respectively. The change speed arms are pivotable, following operation of the shift levers, for controlling change speed rates of the stepless transmissions. The change speed arms are also operable by a pair of right and left auxiliary levers to move toward a backward drive position regardless of speed setting position of the speed control lever. A constant speed straight cruising run is obtained by retaining the speed control lever in a selected position to operate the change speed arms of the right and left transmissions substantially the same amount.Type: GrantFiled: April 8, 1992Date of Patent: September 28, 1993Assignee: Kubota CorporationInventors: Junichi Kitamura, Yoshio Tomiyama, Hiroshi Oshima
