Abstract: A catalyst for methane synthesis is made up from layered double hydroxides represented by the following general formula (1). [M2+1-xM3+x(OH)2]x+[An?x/n·yH2O]??(1) In formula (1), M2+ is Ni2+ and M3+ is Al3+ or Cr3+. Further, An? is CO32?. Furthermore, the term x lies within a range of 0.19 to 0.34 (0.19?x?0.34), and y is 0 or a positive integer.

Abstract: An electrosynthesis system is equipped with an electrolysis device that carries out electrolysis on carbon dioxide gas and water vapor, a synthesizing device that synthesizes a hydrocarbon gas from hydrogen gas and carbon monoxide gas that are generated by the electrolysis, and a control device. The control device adjusts a flow rate of the water vapor supplied to the electrolysis device, in a manner so that a first concentration ratio, which is a concentration ratio between the hydrogen gas and the carbon monoxide gas in a mixed gas discharged from the electrolysis device and containing the hydrogen gas and the carbon monoxide gas, becomes a predetermined target concentration ratio.

Abstract: A superconducting magnet according to one embodiment includes: a coil including a superconducting layer having a first portion and a second portion, and a joining portion; and a cryostat in which the coil is stored. The first portion and the second portion are located in a termination portion. The superconducting layer forms a closed loop by superconducting joining of the first portion and the second portion at the joining portion. The superconducting layer is made of a high-temperature superconductor. A current flows through the joining portion in a superconducting state when a magnetic field equal to or greater than 1.0 tesla and equal to or less than 5.0 tesla is applied to the joining portion at 77 kelvin. The cryostat is configured such that a temperature inside the cryostat is equal to or greater than 2.0 kelvin and equal to or less than 77 kelvin.

Abstract: In a coin mechanism to which the present invention is applied, a coin of five hundred yen whose holding is released is distributed by a fifth distributing device to a return passage or a coin containing passage. The coin of five hundred yen distributed by the fifth distributing device is distributed by an eighth distributing device to a coin tube or a coin box. As mentioned above, the coin whose holding is released is distributed to a change outlet, the coin box, or the coin tube at a front stage of entering the coin containing part. Accordingly, it is unnecessary to provide another distributing device at a part of the coin tube like the prior art, and the number of coins to be contained in the coin tube is increased. Furthermore, it is possible to set the number of coins to be contained in the coin tube at a small number.

Abstract: In a coin pay-out device to which the present invention is applied, the rotary arm of the second change slide is extended to a space between adjacent first change slides and the rear end side of the rotary arm is used as a stopper for disabling the rotation of the rotary arm. Consequently, it is possible to dispose the solenoids of the second change slide and the solenoids of the first change slides side by side. As a result, the disposition space of each solenoid can be reduced both in the transverse direction, as well as in the front-rear direction, thereby the whole size of the coin pay-out device can be reduced. Furthermore, because the second change slide is the rotary arm that turns around the fixed supporting member having a movable supporting member at its tip, which is to be fit in the guide groove of the pay-out link, the second change slide is simplified in structure.
