Abstract: A control system includes multiple industrial devices each belonging to one or more communication domains of multiple communication domains set in the same industrial communication network such that industrial devices belonging to the same communication domain communicate with each other. One or more industrial devices of the industrial devices include processing circuitry that stores domain information indicating whether or not the one or more communication domains to which the one or more industrial devices belong is a secure domain in which secure communication is performed, performs security processing related to the secure communication when the domain information indicates the secure domain, and performs the secure communication based on the security processing.

Abstract: An industrial device communication system comprising: industrial devices that function as communication masters; industrial devices that function as communication slaves that receive control data from the industrial devices that function as communication masters; communication lines that communicably connect the industrial devices to one another; one or more switches for causing a communication group including the industrial devices that function as communication masters and the industrial devices that function as communication slaves to communicate independently from one or more other communication groups; and one or more switch controllers that control the one or more switches, causing the switches to switch between a state in which an inter-group communication line present between the communication group and the one or more other communication groups is disconnected, and a state in which the disconnected inter-group communication line is connected, according to the communication group that independently co

Abstract: An industrial network apparatus includes: a control data communicator configured to transmit control data in a priority transmission period that occurs periodically; and a message data communicator configured to determine whether or not to start transmission of message data in a non-priority transmission period depending on a required transmission time of message data and remaining time of the non-priority transmission period that is different from the priority transmission period, and to transmit the message data when determining to start transmission of the message data.

Abstract: A display device includes a display part made of a roll-up sheet-like direct-view display element; a take-up part attached on one end of the display part, the take-up part allowing the display part to be rolled up; a pulling part attached on the other end of the display part, the pulling part allowing the display part to be roll out; and a holding part for holding the display part from behind. The holding part is formed of linkage, which can be stored on the rear surface of the display part when the display part is rolled up, and can be stretched across the rear surface of the display part when the display part is rolled out. This enables the holding part to be stretched across the rear surface of the display part when the display part is spread out so as to prevent the display part from swaying, thereby maintaining excellent display.

Abstract: A radiator (3) is coupled by caulked joints with fitting plates (5, 15) fixed to the substrate (8) by soldering. By heat-conductively attaching the fitting plate (5, 15) to both sides of the radiator (3), apertures (7) for receiving a prying tool (6) are formed between the radiator (3) and the fitting plate (5, 15). The fitting plate (5, 15) is pried open by the typical tool, thereby the radiator (3) is easily separated from the substrate (8) in order to be used as recycling resources.

Abstract: In a chassis connection apparatus and a chassis formed by using it, a front operation block fixed to a housing by means of a claw-shaped lock mechanism is connected to a chassis frame with a main circuit installed thereon at the back of the front operation block. The chassis can be taken out of the housing by merely pulling the chassis frame backward and releasing a claw-shaped lock. In the construction described above, an engagement section is disposed in a section where the chassis connection apparatus is connected to the chassis frame, so that the chassis frame can be connected at a later time.

Abstract: A component with an unlock mechanism is unlockably locked with respect to another component by a resilient snap tooth engaging in a hole defined in the other component. To unlock the components from each other, the unlock mechanism is pulled between the components to force the snap tooth out of the hole against its resiliency. The unlock mechanism has a slant surface that slides against a slant surface of the snap tooth to displace the snap tooth out of the hole in response to the movement of the unlock mechanism.
