Abstract: A control device includes an inverter circuit having a plurality of switching elements forming three upper and lower arms corresponding one-to-one to the phases of a three-phase motor. The control device includes a shunt resistor, a control circuit that outputs a PWM drive signal to the inverter circuit, and an amplifier circuit. During a regular control, a motor control section changes a pulse signal that controls switching of the switching element. The motor control section sets the switching element included in the arm located on a potential line side to which the shunt resistor is connected to a state in which current does not flow by changing the pulse signal. In this state, the current value acquisition section acquires the offset voltage converted by the shunt resistor.

Abstract: A contact member comes into contact with a back surface of a recording material between a nip portion and a transfer portion in a conveyance direction of the recording material. The contact member is capable of being located at a first position, a second position, and a third position. A detection unit detects a position of the contact member so that the detection unit can detect the first position, the second position, and the third position. The contact member reaches the third position by being biased by the recording material from the second position.

Abstract: An image forming apparatus includes a belt rotating member forming, with the rotating member, a nip portion for fixing a toner image to the recording medium, first and second rollers rotatably supporting the belt rotating member, a stepping motor tilting the first roller, an output unit outputting an amount-of-rotation signal instructing an amount of rotation of a rotor in the stepping motor, an electric current control unit controlling electric current to be fed to a coil in the stepping motor based on the amount-of-rotation signal, and a notifying unit. The notifying unit provides a predetermined notification in a state that an image formation process can be executed based on an output from a detecting unit configured to detect a position of the first roller and a value counted by a measuring unit counting the amount of rotation instructed by the output unit.

Abstract: An image forming apparatus including a sheet storage portion in which a plurality of sheets is stored; a heater which heats air; a fan which sprays air on the sheet stored in the sheet storage portion; and a controller which controls the heat of the heater and controls the drive of the fan, in which the controller controls the heat of the heater at a first temperature before a drive time of the fan reaches a threshold value set in advance, the drive time being in which the fan sprays air heated by the heater on the sheet, and when the drive time of the fan reaches or exceeds the threshold value set in advance, controls the heat of the heater at a second temperature lower than the first temperature.

Abstract: According to one embodiment, a medical image diagnosis system includes a gantry, a rail, an absorbing member and a carrier unit. The rail is disposed on a floor. The rail cover covers the rail. The absorbing member is formed between the floor and the rail cover. The carrier unit is formed in a bottom of the gantry, and is moved along the rail through a space between the rail and the rail cover, and along with movement, attaches and detaches the rail cover with respect to the floor via the absorbing member.
