Abstract: An exhaust gas purification catalyst device includes a substrate and one or more catalyst coating layers on the substrate, wherein the one or more catalyst coating layers include copper ion-exchanged zeolite and alkali-containing zeolite containing one or more metals selected from among alkali metals and alkaline earth metals, the exhaust gas purification catalyst device satisfying either of the following conditions (A) and (B): (A) both the copper ion-exchanged zeolite and the alkali-containing zeolite are contained in one of the catalyst coating layers, and (B) the catalyst coating layer includes a first catalyst coating layer containing the copper ion-exchanged zeolite and a second catalyst coating layer containing the alkali-containing zeolite, with the first catalyst coating layer and second catalyst coating layer being layered together in direct contact.

Abstract: A microreactor which reduces workload of an operator without risk of contamination by foreign substances such as a temperature control liquid. The microreactor produces a product by mixing at least two types of raw material and includes plates which are stacked on each other. One of the plates includes an inlet (first and second raw material inlets) which allows the raw material to be introduced into the inlet, a product outlet which allows a solution containing the product to be discharged from the outlet, a temperature control liquid inlet which allows a heat medium for temperature control to be introduced into the inlet, and a temperature control liquid outlet which allows the heat medium to be discharged from the outlet. The inlet, the product outlet, the temperature control liquid inlet, and the temperature control liquid outlet are located on the same face of the one of the plates.

Abstract: A conveying device includes a sensor to read a sheet to be conveyed, a first conveyor arranged on an upstream side from the sensor in a sheet conveying direction of the sheet, a second conveyor arranged on a downstream side from the sensor in the sheet conveying direction, and correcting circuitry to correct a distance of the sheet having an error detected when the sensor reads the sheet conveyed by the first conveyor and the second conveyor, to an actual distance. The correcting circuitry uses at least a first correction value correcting a distance read by the sensor when the first conveyor conveys the sheet and a second correction value correcting a distance read by the sensor when the second conveyor conveys the sheet.

Abstract: A device includes a head to perform an operation on a conveyed object; a head moving device to move the head in a width direction orthogonal to a conveyance direction of the conveyed object; a position detector to detect a position of the conveyed object in the width direction; a speed detector to detect a moving speed of the conveyed object in the width direction; a position predictor to obtain a predicted width position of the conveyed object after a predetermined period, based on a detected position of the conveyed object and a detected moving speed of the conveyed object; a speed calculator to calculate a travel speed of the head; and a head travel controller to control the head moving device to move the head at the calculated travel speed. With the calculated travel speed, the head arrives at the predicted width position after the predetermined period.
