Patent number: 12099868Abstract: An output management device, an output management method, and a program are provided that manages output of input data to a processing module. The processing module is associated with first metadata indicating a condition of the input data. The input data is associated with second metadata indicating an attribute of the input data. The input data is temporarily stored in the data buffer. Output of the input data from the data buffer to the processing module is controlled by an output control unit. In the output management apparatus, a first acquisition unit acquires the first metadata. A second acquisition unit acquires the second metadata. A notification unit notifies the output control unit of whether or not the input data is allowed to be output to the processing module based on the first and second metadata.Type: GrantFiled: November 29, 2018Date of Patent: September 24, 2024Assignee: OMRON CorporationInventors: Tetsuji Yamato, Taiji Yoshikawa

Patent number: 8482180Abstract: An inner rotor type brushless motor includes a stator. The stator is made of a plurality of stator sections. Each one of the stator sections has a plurality of core members, an insulator, and a winding wound on the core members via the insulator. The core member includes a yoke portion and a tooth portion. The insulator includes a ring portion to connect the core members. Since each stator section can provide sufficient distance and space between two core members on the same stator section, it is easy to wind the winding on the tooth portions. The stator sections can be assembled along an axial direction to form the stator. The yoke portions are circumferentially arranged to connect each other to form a magnetic path.Type: GrantFiled: September 7, 2011Date of Patent: July 9, 2013Assignee: ASMO Co., Ltd.Inventors: Akihiko Seki, Tetsuji Yoshikawa, Masato Kamimura

Patent number: 5043035Abstract: In a method of disassembling resin-molded equipment, a gap is formed in the boundary portion between a metal body and a resin layer disposed around the metal body in order to separate the metal body is separated from the resin layer. To form the gap, either the metal body or the resin layer may be heated, so that the gap is formed by the difference in thermal expansion between the metal body and the resin layer. Alternatively, a microorganism such as ray fungus of Nocardia is attached to the boundary portion between the metal body and the resin layer, and decomposes the resin to form the gap. Since the gap reduces the bonding strength between the metal body and the resin layer and in some cases the metal body may even separate from the resin layer, the metal body may be pulled out with ease.Type: GrantFiled: January 11, 1991Date of Patent: August 27, 1991Assignee: Kabushiki Kaisha ToshibaInventor: Tetsuji Yoshikawa
