    摘要: An image recording apparatus includes a rotating photosensitive drum, a developing unit, a neutralizing device, and a transferring device. An electrostatic latent image is formed on a charged surface of the rotating photosensitive drum, the electrostatic latent image being developed by a developing unit and subsequently transferred by a transferring device to a print medium. The neutralizing device neutralizes the charged surface of the photosensitive drum at the point on the surface disposed downstream of the developing unit and upstream of the transferring device with respect to rotation of the photosensitive drum. A controller controls the neutralizing device according to characteristics of the print medium such as size, material, insulation, and transparency. The neutralizing device may be operated in different modes. For example, the neutralizing device may neutralize an entirety of the charged surface of the photosensitive drum only if the print medium is of a predetermined characteristic, i.e., an insulating sheet such as a transparent OHP sheet or may neutralize only selected parts of the charged surface of the photosensitive drum according to a width of the print medium.

    摘要: In a semiconductor device in which a source/drain and a wiring layer are connected to each other through an associated buried conductive layer on an upper portion of a gate electrode is made small to manufacture a highly reliable and fine MOS transistor. After a silicon oxide film has been formed on a first polycrystalline film to be aligned with a width of a gate electrode, a second polycrystalline silicon film formed on the whole surface of a substrate is selectively etched away so as to be left only on both side faces of a pattern of the silicon oxide film. Thereafter, the first polycrystalline silicon film is selectively etched away with both the silicon oxide film and the second polycrystalline silicon film as an etching mask so that the first polycrystalline film is separated with a width which is smaller than that of the gate electrode by a width of a pattern of the second polycrystalline silicon film. As a result, the buried conductive layer including the first and second polycrystalline silicon film is formed.

    摘要: A recovery mechanism is provided with an elastic blade for wiping the formation surface of ink discharge ports of a recording head by allowing the leading end of its wiping surface to slide on the formation surface of ink discharge ports of the head, and an ink jet recording apparatus is provided with such recovery mechanism. For this recovery mechanism, a guide wall unit, which is extended to the vicinity of the formation surface of ink discharge ports, is arranged along the wiping surface of the blade in a state that the blade is in a wiping operation, and then, ink adhering to the leading end of the wiping surface of the blade is guided to a gap between the guide wall unit and the blade. In this way, the flying splash of ink at the time of wiping can be suppressed for the assurance of a stabilized wiping operation, thus making it possible for the recovery mechanism and the ink jet apparatus provided therewith to perform a high-quality recording.

    摘要: A device for controlling the power supplied to windings of a stepping motor includes a pulse generator for splitting one step drive period of the motor into a plurality of sections, the number of sections and increasing or decreasing depending upon the drive frequency. The pulse generator, also sets the duty cycle of a pulse applied to the motor. The device also includes a stepping motor drive circuit for exciting each phase of the motor with a current determined by the duty cycle of pulse, and a duty changing device for changing the duty cycle for each of plural sections in one excitation phase of the stepping motor, wherein a current wave input into the motor can be maintained as a sinusoidal wave from low-speed rotation to high-speed rotation of the motor by changing the number of sections in excitation depending upon serial drive operations, thereby achieving motor control with less rotation inconsistencies and less noise.
