    摘要: A photo-electric converter principally constructed with a photo-electric conversion unit wherein m.times.n photo-electric conversion elements, each having a light receiving window to form a pel and constructed with a layer of light receiving body and two electrodes provided on both sides thereof, are arranged two-dimensionally in an array of m ranks and n files, and wherein the light receiving windows of the photo-electric conversion elements constituting a rank are arranged at an equally spaced pitch of an integral multiple of that of pels. A signal processing circuit processes and produces as an output a signal which has been subjected to the photo-electric conversion in the photo-electric conversion unit.

    摘要: A recording apparatus for recording an image sensed by a photosensor comprises an inlet for accepting a liquid to be delivered to an outlet orifice through a liquid flow path. Liquid is supplied to the inlet for flow through the liquid flow path to a heating element, which heats liquid in the liquid flow path in response to signals received by the photosensor. Heating is sufficient to cause a change of state of the liquid (that is, to generate a bubble) and produce a force acting on the liquid which overcomes the surface tension of liquid at the orifice and thereby projects a droplet of liquid from the orifice. The temperature of the heating element is raised at each actuation to a temperature above the maximum temperature at which the liquid in the liquid flow path is subjected only to nucleate boiling so as to promote substantially instantaneous transfer of heat to the liquid proximate to the heating element and to retard the transfer of heat from the heating element to liquid at other locations in the liquid flow path.
