Abstract: A color thermal printer a conveyor for conveying a color thermosensitive recording sheet along a conveying path. A thermal head thermally records a full-color image to the recording sheet being conveyed. A fixer lamp applies ultraviolet rays of a predetermined range of wavelength to the recording sheet being conveyed, for optically fixing the recording sheet. In the thermal printer, a printer casing has a small height, and includes a front panel oriented vertically. An insertion opening in the front panel is adapted to insertion of the recording sheet before the recording, and ejection of the recording sheet after the recording. An air inlet and an air outlet are formed in the front panel. The insertion opening is disposed between the air inlet and the air outlet. An air passageway is disposed in the printer casing, and communicates from the air inlet to the air outlet via at least a portion of the conveying path.

Abstract: A guide member is disposed between a thermal head and a conveyor roller pair. The guide member projects into a conveyance passage of a recording paper when a platen roller is separated from the thermal head. In this state, the guide member abuts on the recording paper having been forwarded by the conveyor roller pair. Further, the guide member guides the recording paper to feed it between the platen roller and the thermal head. When the platen roller is pressed against the thermal head, the guide member is pushed by support plates of the platen roller. The pushed guide member is lowered so that the guide member is evacuated from the conveyance passage of the recording paper.

Abstract: The present invention relates to a lean combustion gas engine which receives a drive output by means of supplying and combusting gas fuel in a main combustion chamber. The lean combustion engine of the present invention comprises: a main combustion chamber (1) which is surrounded by a piston (3), a cylinder (2) and a cylinder head (4); a precombustion chamber (30) equipped with a pilot fuel injection valve; and a spark plug (11) which serves as an ignition source for the fuel-air mixture within the main combustion chamber; wherein, the spark plug and pilot fuel injection valve-equipped precombustion chamber are provided in said cylinder head.

Abstract: In a one-pass multi-head type color thermal printer, a color recording material is transported by a plurality of feed roller pairs, each of which consists of a capstan roller and a pinch roller and is disposed behind one of a plurality of thermal heads. The pinch roller is movable relative to the capstan roller to nip the recording material, and the capstan roller is driven each individually to transport the recording material at an appropriate speed through each of the thermal heads. A platen roller is disposed in opposition to each of the thermal head so as to be movable to and from the opposed thermal head, whereas the thermal heads are mounted stationary.

Abstract: A lay down arc welding electrode with improved weld penetration is described. The welding electrode includes a core wire surrounded by flux, a portion of which has been longitudinally removed or has been otherwise made thinner than the flux surrounding the remainder of the arc wire. The direction of arc is adjusted by varying the shapes of core wire and flux. During welding the arc welding electrode rests on a tack weld. This causes directional angle (.alpha.) to the root of the weld to increase and the divergence angle (.beta.) to decrease, resulting in improved penetration of disposed metal. An apparatus is described for continuous lay down arc welding using the described arc welding electrode.
