Abstract: An image recording apparatus according to this invention includes a frequency divider 22 for generating a reference signal of a frequency higher than that of a dot clock signal, a pulse exposure control circuit 31 for causing a laser beam emitted from a laser diode 27 to irradiate a recording medium when both an image signal and the reference signal are ON, and a switching device 25 for switching between a first recording mode for causing the laser beam emitted from the laser diode 27 to irradiate the recording medium when the image signal is ON, and a second recording mode for causing the laser beam emitted from the laser diode 27 to irradiate the recording medium when both the image signal and reference signal are ON.

Abstract: A laser light source has a plurality of semiconductor lasers arranged in a direction intersecting a primary scanning direction X. The semiconductor lasers are arranged in such a positional relationship that each semiconductor laser is located upstream, in the primary scanning direction X, of a different semiconductor laser located adjacent thereto and downstream thereof in a direction in which air is blown from an air blowoff pipe.

Abstract: When rotating a recording drum at low speed, air is jetted from air jet ports toward a point of irradiation, in a direction to diffuse a gas generating from an image recording medium upstream with respect to a direction of rotation of a recording drum. An air curtain approximately semicircular about the point of irradiation is formed upstream thereof with respect to the direction of rotation of the recording drum. As a result, the gas can hardly diffuse from the point of irradiation upstream with respect to the direction of rotation of the recording drum. The gas is collected from a gas suction opening. Thus, the gas is reliably prevented from contacting the image recording medium having an image recorded thereon.

Abstract: An image recording apparatus (1) causes a recording head (20) to move through a distance corresponding to one half of the recording width of the recording head (20) in a sub-scanning direction each time a recording drum (10) makes one rotation. This, light emitting devices (23, 24) record two line data in advance, and thereafter following light emitting devices (21, 22) record the same line data repeatedly at the same position. This increases the energy of laser light beams given to a recording position on a printing plate (P) to accomplish the recording of an image with reliability. The recording speed is not extremely decreased because not all light emitting devices (21 to 24) are used to make the repeated recordings at the same position on the printing plate (P). Further, the construction of optical systems and driving systems in the image recording apparatus is not complicated.

Abstract: In a semiconductor device having SiC vertical trench MOSFETs, it is aimed to prevent the generation of large scattering in the channel resistance without largely increasing the average value of channel resistance. A 4H-SiC substrate having a major face thereof that is generally a {0001} face and having an off angle ?. The trench is formed with the standard deviation ? in scattering of the angle formed by a trench side wall face and a substrate major face within a wafer face. By setting the designed value of the angle formed by the trench side wall face and the substrate major face at an any angle ranging from [(60 degrees)+2?] to [(90 degrees)?tan?1 (0.87×tan ?)?2?] in forming the trench in the SiC substrate, a semiconductor device in which the angle formed by the trench side wall face and the substrate major face is 60 degrees or more but not more than [(90 degrees)?tan?1 (0.87×tan ?)] can be obtained.

Abstract: In a separator for separating a stripping sheet from a composite film formed by a base sheet and the stripping sheet which are superposed with each other, the composite film is first so carried and arranged that its forward end portion extends over a separating clearance formed in a support, and then a blade is pushed into the separating clearance for thrusting the composite film into the separating clearance in a bent state. Thus, the forward end portion of the composite film is separated (i.e., delaminated). Thereafter the base sheet and the stripping sheet are independently sucked/held on the delaminated forward end portion, and the stripping sheet is completely separated from the base sheet while widening the space between the held positions of these sheets. Due to the aforementioned structure and operation, the composite film can be separated in a simple structure with minimum force, and the separator can be reduced in size and power.

Abstract: An image recording apparatus comprises a temporary storing magazine for temporarily retaining a recorded photosensitive material sheet. The temporary storing magazine stocks the recorded photosensitive sheet received therein from an image recording section while discharging the recorded photosensitive material sheet into an automatic developing machine. Hence, image recording is executed without interruption and parallel to discharge of the recorded photosensitive material sheet into the developing machine, enhancing the capability of the image recording apparatus.

Abstract: In a printing apparatus, a supply pallet storing an original and a photosensitive film is located above a printer. The films are carried onto a transparent plate of the printer in this order by a carrier. Then, light from a light source of the printer is directed toward the transparent plate, whereby an image provided on the original film is printed onto the photosensitive film. Thus, the printing apparatus is small in plane size.
