Abstract: An image forming apparatus includes a photosensitive member, an intermediate transfer member, a moving member, a driving motor, a stepper motor, a detector, a phase determiner, and a controller. The stepper motor drives the moving member to move between a first position at which the photosensitive member contacts the intermediate transfer member and a second position at which the photosensitive member contacts the intermediate transfer member are separated. The controller includes a first control mode to control a motor based on a predetermined current magnitude and a second control mode to control a motor by vector control. The controller starts driving the driving motor in the first control mode, and then switches from the first control mode to the second control mode. The controller controls the stepper motor in the first control mode during a period from when the stepper motor is activated to when the stepper motor is stopped.

Abstract: An image forming apparatus includes an image forming unit to form an image on a sheet, a conveyance roller, a motor, a gear train, a detection unit to detect motor driving current, a phase determination unit to determine a motor rotor rotation phase, and a control unit having first and second control modes. The control unit rotates the rotor to rotate the conveyance roller in a predetermined direction, and rotates the conveyance roller in a direction opposite to the predetermined direction. The control unit controls the driving current in the second control mode, and then switches, in response to a value corresponding to a rotor rotation speed having reached a target speed, from the second control mode to the first control mode to control the driving current. The target speed is a speed which corresponds to a speed when the conveyance roller conveys the sheet and is a constant value.

Abstract: An image forming apparatus includes a power source, a motor, a motor control device, a first switching element, a controller, a detector, a discriminator, and a first setting unit configured to set a control value. The motor control device includes a phase determiner configured to determine a rotational phase by using the control value, and a second setting unit. The motor control device includes a first mode and a second mode. The discriminator discriminates a type of the motor in the first mode. The motor control device executes the first mode if the controller controls the first switching element in response to supplying of the power. The motor control device does not execute the first mode even if the power is supplied to a driving circuit, when the controller controls the first switching element in response to inputting of a trigger signal.

Abstract: A motor control apparatus operable to control a motor includes a phase determiner for determining a rotational phase of a rotor of the motor, and a controller having a first control mode for controlling a driving current flowing through a winding of the motor based on a current of a predetermined magnitude, and a second control mode for controlling a driving current flowing through the winding so that a deviation between a command phase representing a target phase of the rotor and a rotational phase determined by the phase determiner is reduced. The controller executes the first control mode without executing the second control mode in a case of rotating the motor in a first direction, and executes the second control mode in a case of rotating the motor in a second direction which is a reverse direction to the first direction.

Abstract: When field strengthening is constantly performed during driving by a drive motor to inhibit a rotating speed of the drive motor from suddenly fluctuating, power consumption is increased. The field strengthening is performed only during a period during which the field strengthening is required to be performed. Thus, it is possible to reduce a period during which a current value is set to a d-axis current command value (the field strengthening is performed) while the motor is driven. This can prevent increased power consumption.

Abstract: An image forming apparatus having below arrangements. A plurality of image forming units form a plurality of images which are transferred onto a transfer belt. A detection unit detects a position of the transfer belt in a belt width direction. A position adjusting unit adjusts the position of the transfer belt in the belt width direction according to a detected position. A calibration unit calibrates an adjustment amount for adjusting color registration based on a detected position of patterns formed onto the transfer belt.

Abstract: An image forming apparatus comprising image forming units, an image bearing member for bearing images, a table indicative of a correspondence relationship between temperature and an amount of a color misregistration. A pattern detection unit detects color registration patterns on the image bearing member. A calculation unit calculates the amount of the color misregistration based on the detection result of the patterns. A color registration adjustment unit has a first mode in which color registration adjustment is performed based on the amount of the color misregistration, and a second mode in which the amount of the color misregistration is predicted based on temperature using the table and the color registration adjustment is performed based on the predicted amount. An updating unit makes the image forming units form the color registration patterns when the temperature reaches a predetermined temperature, and updates the table based on the amount of the color misregistration.

Abstract: It is intended to provide a diagnosis method and diagnostics for cancers such as human glioma and a therapeutic method and remedies for cancers such as human glioma by identifying tumor suppressive genes or cancer genes useful in diagnosing or treating cancers such as human glioma. Tumor suppressive genes such as RFX1 gene and BGT-1 gene and cancer genes such as HOXD9 gene are screened by comparing a human glioma- or human glioma cell line-origin genomic DNA with a normal tissue-origin genomic DNA in the degree of methylation in CpG island cytosine residues.
