Abstract: An output system includes a terminal device, an image-forming apparatus, and a server device. The terminal device includes an acquirer that acquires content from the server device, a generator that generates job data including a setting for outputting the content based on the acquired content, a transmitter that transmits the job data to the image-forming apparatus, and a reception slip outputter that outputs a reception slip including a reception number corresponding to the generated job data. The image-forming apparatus includes a receiver that receives the job data from the terminal device, and an outputter that outputs the content after executing a job based on the job data corresponding to the reception number when the reception number is input.

Abstract: A nitrate solution which is a substance to be treated is heated and denitrated using microwaves, by introducing the substance directly into a cylindrical oven to which microwaves are applied, horizontally rotating the oven about a vertical axis, detecting the amount of reflected waves of the applied microwaves with time to observe the heating condition of the substance, and controlling microwave power to be applied according to the detected amount of the reflected waves and the change in the amount of reflected waves with time. The cylindrical oven preferably has a construction capable of being separated into a stationary upper part and a horizontally rotatable lower part constituting a closed-bottom vessel. These two parts are combined through a choke coupling mechanism to form the oven. According to the detected values of the reflected waves, the precise control of the microwave power applied to the substance to be treated can be conducted at a suitable time.
