An electric machine system includes an electric machine, an electric power converter, and a control unit. The electric machine includes a stator that includes coils, and a rotator that includes a magnet and is rotatable with respect to the stator. The electric power converter inputs electric power with respect to the coils of the electric machine. The control unit controls the electric power converter. The control unit includes an output unit and a correction unit. The output unit outputs a control signal for operating the electric power converter to the electric power converter. The correction unit corrects a phase of the control signal that determines input timing of the electric power with respect to the coils of the electric machine. The correction unit corrects the phase so that the magnitude of the electric power approaches an extreme value.

An image forming apparatus includes, an image forming portion configured to form a toner image on a sheet using printing toner and apply powder adhesive on the sheet, a fixing portion configured to heat the toner image formed on the sheet and the powder adhesive applied on the sheet by the image forming portion and fix the toner image and the powder adhesive to the sheet, and a bonding portion configured to bond the sheet with the powder adhesive by reheating the sheet having been heated by the fixing portion. The bonding portion is arranged above the image forming portion.

Image forming apparatus

An air-conditioning system includes: an outdoor unit including an outdoor-side control device; indoor units each including an indoor-side control device controlling a device in response to an instruction; communication lines connecting the outdoor unit and the indoor units for communication between them; and a remote control unit including a remote-control controlling device and wirelessly communicating with each indoor unit. Each indoor unit includes an indoor-side setting device that determines an identification number identifying the indoor unit. When receiving, from the remote control unit, a signal including the instruction, the indoor-side control device determines whether or not to control the device based on an identification signal, and sends the signal to the outdoor unit via a communication line. The outdoor-side control device determines which indoor unit is an instruction target based on the identification signal and sends the signal to the instruction target indoor unit, via a communication line.
