Abstract: An ink set with which it is possible to effectively prevent bleeding of aqueous ink even in the case when printing takes place at high speed by means of an inkjet discharge recording method. This ink set includes a pretreatment ink and an aqueous ink and is used for a recording method in which the respective inks are discharged on a base material as an inkjet. The respective inks included in said ink set have static surface tensions that satisfy the following relation: static surface tension SP of the pretreatment ink<static surface tension SC of the aqueous ink.

Abstract: A remote control device includes, in one housing: a communication functional unit that communicates with a programmable controller; an input/output functional unit that outputs control-target-device control information for controlling an operation of a control target device to the control target device on the basis of remote-control-device control information, which is output from the programmable controller and is used for controlling the remote control device, and to which operation result information, which is output from the control target device and indicates an operation result of the control target device that operates on the basis of the remote-control-device control information, is input; a backup managing unit that creates backup data for internal data stored in the remote control device; and a nonvolatile memory that stores the backup data.

Abstract: An analog input unit configured to be included in a programmable controller and to sequentially convert analog values input from outside into digital values, the analog input unit includes: an analog-to-digital conversion unit that converts an analog value being a measurement value of a flow meter into a digital value; a flow computation unit that calculates an instantaneous flow and a total integrated flow that is obtained by integrating a flow per setting time set in advance, based on the digital value from the analog-to-digital conversion unit; and a storage unit that includes a flow storage area for storing therein the instantaneous flow and the total integrated flow calculated by the flow computation unit.
