Application No. 08/505,020
The appellant's invention relates to an ink jet apparatus
and a conductive ink mixture. An understanding of the
invention
can be derived from a reading of exemplary claims 10 and 16,
which are reproduced as follows:
10. An ink jet apparatus, comprising:
a storing section for storing an electrically conductive
ink containing an electrically conductive liquid and an
electrically conductive material having an electrical
conductivity higher than that of the conductive liquid, said
conductive material comprising a plurality of conductive
particles having at least conductive surfaces with electrical
conductivity to generate heat thereat;
electrode means located in the storing section for
applying an alternating current to said conductive ink stored
in the storing section, said conductive particles in said
conductive ink allowing the alternating current to flow
therethrough and generating heat thereat for forming bubbles
in the conductive liquid by a skin effect caused by
application of said alternating current; and
a nozzle attached to the storing section for ejecting the
conductive ink due to generation of said bubbles by
application of the alternating current.
16. A conductive ink comprising an electrically
conductive liquid and an electrically conductive material
dispersed in said conductive liquid, said conductive material
having an electrical conductivity higher than that of said
conductive liquid and comprising a plurality of conductive
particles to allow an alternating current to flow through the
