Abstract: An information processing apparatus includes a processor. A first power-off state, which accompanies a reset of hardware and a restart of a program, and a second power-off state, which does not accompany the reset of the hardware and the restart of the program, are defined as states of a power supply of the information processing apparatus. The processor is configured to record, if an operation for turning off the information processing apparatus is performed and the power supply enters the second power-off state, a change in a state of the power supply to the second power-off state, and change the state of the power supply to the second power-off state if a change in the state of the power supply to the second power-off state is recorded after supply of power to the information processing apparatus is stopped and power is again supplied to the information processing apparatus.

Abstract: An image forming apparatus includes: a processor configured to: execute a linking application for a linkage with a specific service, to receive a linkage request from a user through the specific service; and perform an authenticating process that authenticates a user who uses the image forming apparatus, using user information on the user who uses the specific service linked as a result of an approval of the received linkage request.

Abstract: An information processing apparatus includes a processor configured to, in a case where a time specified processing instruction to execute a specified process at a specified time is set, in response to detecting presence of a user near the information processing apparatus upon restoration from an energy save mode to a normal operation mode, hold a time specified processing instruction scheduled for a past specified time that is time before the restoration, the time specified processing instruction being held not to be executed upon the restoration.

Abstract: To provide a method of sintering an optical fiber porous glass base material, capable of sufficient dehydration and reducing a transmission loss caused by residual moisture by efficiently transferring heat from the heater to the base material during a process in dehydration/sintering for an optical fiber porous glass base material, a porous glass base material having a heat shield plate installed in a vicinity of a lower end is vertically inserted into a furnace core tube provided with a heater along an outer circumference, and heating using the heater is performed. The heat shield plate has an outer diameter which is 70% or larger than a diameter of the porous glass base material and smaller than an inner diameter of the furnace core tube.
