我们引入了一种自主的信息热机（即没有任何时间相关参数），但具有独立的测量和反馈过程。该模型是受麦克斯韦妖启发的不同类型信息热机之间的桥梁；从最初的西拉德引擎型系统到自主恶魔装置。通过根据我们之前的论文（Shiraishi and Sakawa 2015 Phys. Rev. E 91 012130）中介绍的总体框架分析我们的模型，我们阐明了积分涨落定理中测量和反馈分离的作用。
We introduce an information heat engine that is autonomous (i.e., without any time-dependent parameter) but has separated measurement and feedback processes. This model serves as a bridge between different types of information heat engines inspired by Maxwell's demon; from the original Szilard-engine type systems to the autonomous demonic setups. By analyzing our model on the basis of a general framework introduced in our previous paper (Shiraishi and Sagawa 2015 Phys. Rev. E 91 012130), we clarify the role of the separation of measurement and feedback in the integral fluctuation theorems.
