Patent number: 7119514Abstract: An inverter has a measuring part that measures an operating time such as the time interval from when a command to start a specified operation by an associated system until a signal indicating the completion of the operation is received. A comparing part compares this measured operating time with a threshold value stored in a memory and an abnormal condition is reported to a host system, depending on the result of the comparison.Type: GrantFiled: January 18, 2006Date of Patent: October 10, 2006Assignee: Omron CorporationInventors: Hiroshi Shimizu, Junichi Ueno, Kimikazu Kubo, Takashi Asai, Masakazu Komatsu, Yasuyuki Tagano, Toshiyuki Ozaki

Publication number: 20060048977Abstract: A crawler tractor comprises steering mechanisms (44) (45) for rotating a machine body by causing right and left crawler belts (9) to move differentially. The tractor is characterized in that the steering mechanism (44) is connected to a drive system located behind a reverser mechanism (21) that moves the machine body forward and back. Even when the machine body movement direction is changed from forward to back, the direction of the steering wheel (18) and the direction of the rotation of the machine body are kept the same, so that a reversed steering phenomenon is prevented from occurring, and an appropriate operation in forward or back movement is enabled with a simple structure that does not require an additional mechanism such as a reverse-steering preventions mechanism.Type: ApplicationFiled: December 5, 2002Publication date: March 9, 2006Applicant: Yanmar Agricultural Equipment Co., Ltd.Inventors: Susumu Akashima, Masakazu Komatsu

Patent number: 6988571Abstract: The purpose of the invention is to enable a crawler tractor to brake and stop certainly without applying a load to an engine and a driving mechanism, and without complicated operation. An operation link links a conic linkage (53) which links a steering wheel (7) with a main speed change lever (55) of the crawler tractor, and with an operation mechanism of a brake pedal (54). A neutral return mechanism for the operation link is provided. The operation link neutral return mechanism comprises a hook-like cam lever (61). When the brake pedal is depressed, the main speed change lever is moved to its neutral position before braking force occurs, and then, the brake is actuated. Accordingly, engine brake is used effectively, and the brake can be miniaturized.Type: GrantFiled: April 3, 2002Date of Patent: January 24, 2006Inventors: Eiichi Okamoto, Masakazu Komatsu, Yukio Kubota, Susumu Nochi, Susumu Akashima, Takashi Uno, Gaku Higashiguchi, Shinsuke Tani, Kazuo Yamamoto

Publication number: 20050201408Abstract: A synchronous controller is formed with a cycle master module and one or more control modules doubly connected through a synchronous bus and an event bus. The event bus is used for transmitting data with a larger volume. The control modules each cyclically carry out execution of a user program for controlling an object apparatus to be controlled. The cycle master module exchanges data with the control modules through the event bus and the synchronous bus. Each of the control modules carries out one cycle of the execution of the user program by using reception of synchronous data transmitted from the cycle master module through the synchronous bus as a trigger.Type: ApplicationFiled: March 9, 2005Publication date: September 15, 2005Inventors: Shuji Otani, Masakazu Komatsu, Yasuhiro Mori
