Title: Ink jet recorder
Inventor: NISHIKAWA MASAHARU
IPC: B41J2/14
Filed: 1985-01-14
Abstract: PURPOSE:To enable high-speed and super-fine recording to be performed by vaporizing and swelling the vaporization component of ink under the Joule effect and feeding the vaporized ink flying in an opening corresponding to a recording head. CONSTITUTION:An ink sheet 33 impregnated with conductive ink retained in an opening 34 is transported in such a manner that it overlaps a stylus electrode 35. A gap is formed between the sheet 33 and the electrode 35, and is filled with ink sticking to the lower surface of the sheet 33 and leaking from the opening 34. If a recording signal voltage is applied between the electrode 35 and the sheet 33, an electric current path is formed by the conductive ink between both. The conductive ink generates a Joule heat by the current because of its high resistance value, so that is vaporizes and inflates the vaporization component of ink solvent, etc. As a result, the vaporized ink in the opening 34 flies in the direction of recording paper 32, thus performing the recording. This enables high-speed and super-fine recording.

Abstract: PROBLEM TO BE SOLVED: To give an alarm even when no current is supplied from a battery for operating an equipment by permitting the current supply of a secondary battery to an alarm display section when the detecting voltage of the battery for operating the equipment is made lower than the threshold. SOLUTION: In a voltage-drop alarm device 1, a voltage detecting means is composed of a TFT(a thin-film transistor) 20, and a gate electrode 5 is kept at a HIGH level and a current is made to flow between a drain and a source in the TFT 20 under the state, in which there is sufficient battery capacity in a battery B for operating an equipment. Consequently, the current of a solar cell 8 is made to flow to the ground side through the TFT 20, and a voltage- drop alarm is not displayed in a liquid-crystal display section 21. When the battery capacity of the battery B for operating the equipment is used up and voltage reaches zero, the liquid-crystal display section 21 is supplied with the current of the solar cell 8 because the gate electrode 5 reaches a LOW level and no current flows between the drain and the source in the TFT 20.  Accordingly, the voltage-drop alarm can be displayed in spite the voltage of zero of the battery B for operating the equipment.
