    摘要: An image forming apparatus includes a driving roller for transporting a medium; a follower roller disposed to face the driving roller for transporting the medium; a guide member for guiding the medium to change a transport direction thereof by an angle greater than 30°; and a rotational member disposed to be freely rotatable at a position corresponding to a side edge of the medium. Accordingly, after the driving roller and the follower roller transport the medium, when the medium contacts with the guide member, side edges of the medium contact with the guide member at an angle smaller than that of a center portion of the medium contacting with the guide member.

    摘要: A method or system for bringing a movable element of a stepper motor to its home position by mechanically blocking the movable element from further moving from the home position, wherein the movable element is moved in one direction by repeating an energization cycle in which windings for sequentially establishing different energization phases are energized in a predetermined sequence at a predetermined interval from one phase to another. After the movable element is mechanically blocked, a motor driver circuit energizes at least one of the windings which corresponds to at least one of the energization phases that precedes another of the energization phases which corresponds to the home position of the movable element. This energization of the winding or windings for each preceding phase continues for a time longer than the predetermined energization interval of the normal energization cycle. Then, the phase corresponding to the home position of the movable element is maintained to hold the motor stopped at the predetermined home position.

    摘要: The present invention provides an N phase/N+1 phase energization type stepper motor controller for alternately energizing an N number and an N+1 number of phases where N is an integer equal to or greater than one. The controller detects which phase(s) is(are) energized at a time when the stepper motor is paused, and sets a starting pulse width for N phase energization to be made shorter than that of N+1 phase energization, in response to the detected results. When the initial energization in starting is N+1 phase, a driving pulse having a width which is longer than that N phase for energization is outputted. The N+1 phase energization has stronger magnetism for rotating a rotor than N phase energization, thereby increasing the rotational speed for starting. When the initial energization is N phase, a driving pulse having a width which is shorter than that for N+1 phase energization is outputted. Thus the magnetism is made stronger so that the starting rotational speed is increased when performing either N+1 phase energization or N phase energization. The period for executing N phase energization is made shorter than that for N+1 phase energization, and the ratio of periods for N phase and N+1 phase energization is kept constant. By shortening the period for N phase energization and extending the period for N+1 phase energization, smooth and constant rotation is obtained.

    摘要: A crystalline semiconductor film in which the position and the size of crystal grains are controlled is provided, and a TFT that can operate at high speed is obtained by forming a channel formation region of the TFT from the crystalline semiconductor film. A heat retaining film is formed on an insulating surface, a semiconductor film is formed to cover the heat retaining film, and a reflective film is formed to partially cover the semiconductor film. The reflective films and the semiconductor film are irradiated with a laser beam. The reflective film creates a distribution in effective irradiation intensity of laser beam on the semiconductor film. The distribution, with the heat retaining effect provided by the heat retaining film, generates a temperature gradient in the semiconductor film. Utilizing these, the position where crystal nuclei are to be generated and the direction in which crystal growth should advance can be controlled and crystal grains having a large grain size can be obtained.
