A heat dissipation fin 14 of the present invention is a heat exchange promotion member that exchanges heat with a flowing fluid. The heat dissipation fin 14 includes a planar part 12 which is a surface substantially parallel to the fluid flowing direction and a raised part 13 that protrudes from the planar part 12 toward the fluid. The raised part 13 has a portion slanted relative to the direction in which the fluid flows, and there are a plurality of the raised parts 13 formed spaced apart from one another in the fluid flowing direction.

Abstract: Arithmetic operation circuits and a verification circuit are formed by loading configuration information into a configuration memory in an FPGA. Arithmetic operation circuits have the same arithmetic operation function, but are different from each other in combination of the circuit blocks. The arithmetic operation circuits are formed by combining the circuit blocks to make the maximum use of the DSP block, while the arithmetic operation circuit is formed by combining the circuit blocks other than DSP block. The arithmetic operation circuits each are configured to use a block RAM as the data hold memory, while the arithmetic operation circuit is configured to use a distributed RAM as the data hold memory. Each of the arithmetic operation circuits receives the input data, and outputs arithmetic operation result data (V1 to V3). A verification circuit compares the arithmetic operation result data to verify whether errors occur.

Abstract: A control arithmetic device controls so that an approval-receiving device displays a content of a new control program that the control arithmetic device received from the editing device. The approval-receiving device receives input of approval information that indicates whether a change of a control program is approved or not from an manager. The control arithmetic device changes the control program to the new control program in the case where the approval information received from the approval-receiving device indicates approval of the control program.

Abstract: A safety device includes a first computation unit, a second computation unit, an output control unit, and a first central processing device. The first computation unit is configured to perform a first computation on a detected value detected from a subject to be controlled, thus obtaining a first result value. The second computation unit is configured to perform a second computation on the detected value, thus obtaining a second result value which is to be determined if equal to the first result value. The output control unit is configured to output the first result value in a case that the second computation unit determines that the first result value is equal to the second result value, and not to output the first result value in a case that the second computation unit determines that the first result value is not equal to the second result value.
