摘要： Motor-control device for an image forming apparatus includes a motor, an encoder, a microcomputer, and a driving circuit. The encoder generates a pulse signal in response to rotation of the motor. The microcomputer includes a CPU, a RAM and a ROM. The CPU detects actual rotational speed of the motor based upon the pulse signal generated by the encoder. The CPU cyclically provides a driving signal by comparing the actual rotational speed with a predetermined target rotational speed of the motor. An operating cycle is proportional to a cycle of the pulse signal generated by the encoder. The driving circuit drives the motor based upon the driving signal provided by the CPU. The CPU determines the operating cycle based upon the predetermined target rotational speed. The CPU also determines whether the motor condition is normal or abnormal by comparing the driving signal with a predetermined reference driving signal.

摘要： An image recording apparatus for recording an image on a photosensitive recording medium employs an elongated continuous form photosensitive recording medium capable of receiving a latent image of an output image to be formed, and a cut sheet type of a developer recording medium which produces an output image upon reaction with the latent image on the photosensitive recording medium. The apparatus comprises an exposing unit having an exposure position at which the elongated continuous form photosensitive recording medium fed along a photosensitive recording medium feeding path is exposed to a light image to form a latent image thereon, a developing unit disposed downstream of the exposing unit with respect to the photosensitive recording medium path which develops the exposed photosensitive recording medium superposed with the developer medium, and a separating unit disposed downstream of the developing unit with respect to the photosensitive recording medium feeding path which separates the exposed photosensitive recording medium from the developer recording medium. The image recording apparatus further comprises a starting unit for starting a recording operation upon user operation thereof, a photosensitive recording medium feeding unit that feeds the photosensitive recording medium from a position downstream of the separation unit to the exposure position through the developing unit, and a prohibiting unit which prohibits the starting of a recording operation when the starting unit is actuated during a time at which the photosensitive recording medium is being fed from the position downstream of the separation unit to the exposure position. The present invention is also applicable to image recording machines which employ a single sheet type of recording medium.

摘要： An overhead projector in which a light from a light source is transmitted through an original, and a resulting original image is projected on a screen by means of a projection optical system including a projection lens and a half-mirror. At the same time, the original image is transmitted through the half-mirror, and delivered to a record medium by means of an exposure optical system. The exposure optical system includes a shutter member which can be shifted between a shielding mode and a copying mode. In the shielding mode, the optical path of the exposure optical system is closed to permit projection on the screen. In the copying mode, the optical path is opened so that the original image, to which the record medium is exposed, is visualized on the record medium by a developing process. At the end of the copying mode, the record medium is discharged into a tray.

摘要： An engine exhaust system for a vehicle is provided in which it is possible to obtain necessary vibration damping performance even when there are layout restrictions. For instance, a spherical joint on a front side of the vehicle and a spherical joint on a rear side of the vehicle, are positioned before and after two catalysts, and the components positioned between the front and rear spherical joints is unsupported by a vehicle body. Hence, a dynamic damper is formed. The resonant frequency of the dynamic damper, i.e. a frequency at which vibrations are absorbed can be adjusted by altering the modulus of elasticity and weight of the dynamic damper. Therefore, the necessary vibration damping performance can be obtained despite layout restrictions.

摘要： A plurality of pattern electrodes which are disposed in correspondence with the printing dots are provided on one surface of a substrate biased in one direction. An anisotropic electroconductive element is supported to enable its release on the substrate which has a first turn-on surface contacting the pattern electrodes on its substrate, and a second turn-on surface contacting the electroconductive transfer sheet and exhibiting excellent conductivity between only its first and second turn-on surfaces. In the printing action, electric conduction is achieved on a transfer sheet depending on the printing pattern from the pattern electrodes through the anisotropic element, so that the resistance layer of the sheet may emit heat, thereby the ink contained within the ink layer of the sheet is melted for printing.

摘要： A drive control system for controlling a drive motor in response to external command signals. The system comprises a first control arrangement for obtaining numerical values corresponding to amounts of successive intermittent operations of the drive motor responsive to respective external command signals, summing the obtained numerical values, and subtracting from a current sum of the numerical values a numerical value corresponding to a non-operation time period during which the drive motor is held at rest between the successive intermittent operations. The system further comprises a second control arrangement for inhibiting the operation of the drive motor responsive to the next command signal, for a length of time corresponding to the current sum after the drive motor has completed each of the intermittent operations, whereby the temperature of the drive motor is kept below an upper limit.
