Abstract: A sheet manufacturing apparatus is an apparatus that heats a material containing fibers to form a sheet, and includes a heating portion that heats the material, and a control portion that controls a temperature at which the heating portion heats the material. The control portion sets a temperature of the heating portion to a first temperature in a first state where the sheet manufacturing apparatus manufactures the sheet, and sets the temperature of the heating portion to a second temperature lower than the first temperature at a predetermined timing in a second state where the sheet is not manufactured, or at a predetermined timing when a state of the sheet manufacturing apparatus is shifted to the state where the sheet is not manufactured.

Abstract: A point management system manages points on the basis of an index related to a financial product, the points being held by a user in a loyalty points program with which accumulated points can be exchanged for a product or the like. The point management system includes a point management unit that, on the basis of a target value and/or a withdrawal value of a point balance in management set on the basis of a tiered unit of exchange in exchanging points for a product or the like, calculates information related to prediction of whether or not the point balance reaches each of the target value and/or the withdrawal value by a term, or selects a financial product with which the point balance is highly likely to reach the target value.

Abstract: A sheet is configured to have a first complex having a fiber and a fiber aggregation inhibitor integrally, a second complex having a fiber and a fiber aggregation inhibitor integrally, and a binding material which combines the first complex and the second complex and contains a resin.

Abstract: Provided is technology improving the efficiency (productivity) of a sheet manufacturing apparatus. A sheet manufacturing apparatus 100 manufactures sheets S by heating with heaters 81 and 82 a mixture (second web W2) of resin and fiber produced by defibrating feedstock MA. The heaters 81 and 82 each have a first roller 171, a second roller 172 that holds the second web W2 with the first roller 171, and a moving mechanism 190. The moving mechanism 190 can switch the first roller 171 and second roller 172 to a position holding the second web W2, and a first roller 171 and second roller 172 are separated and do not hold the second web W2. The heaters 81 and 82 are configured as units that can removably installed to the sheet manufacturing apparatus 100.

Abstract: An airline ticket sales system having a stock recording unit retaining a stock of flights, and a destination candidate extraction unit including: receiving an input of at least one condition from a user via an information processing terminal, information about a destination airport being excluded from the condition; acquiring, from the stock recording unit, information about outbound candidate flights and inbound candidate flights satisfying the condition; extracting, as candidate airports, a predetermined number from airports common to arrival airports of the outbound candidate flights and departure airports of the inbound candidate flights; selecting, based on a predetermined criterion, one from round-trip candidate flights composed of combinations of the outbound candidate flights and the inbound candidate flights among the departure airports of the outbound candidate flights specified by the condition and the respective candidate airports; and regarding the selected one as a to-be-sold round-trip flight.

Abstract: An image forming apparatus includes one or plural forming devices that form respective images on a recording medium that is being transported, a fixing device provided on a downstream side with respect to at least one of the forming devices in a direction of transport of the recording medium and that fixes the images formed on the recording medium, a delivering device that receives the recording medium transported in a first direction and discharges the recording medium in a second direction that is different from the first direction, and a supplying device that supplies the recording medium to any of the forming devices or to the delivering device. The forming devices, the fixing device, the delivering device, and the supplying device have respective housings and are each joinable to any of the other devices.
