Title: Oxygen-mixing etching method and spray-type etching device used therefor
Inventor: SAGARA HIDEJI
IPC: C23F1/08
Filed: 1988-10-21
Abstract: PURPOSE:To smoothly and stably perform etching by quantitatively sending gaseous oxygen into a cupric chloride-based etchant immediately before the etchant is sprayed on a member to be etched. CONSTITUTION:Since gaseous oxygen is quantitatively supplied to the etchant 2, an anionic complex, etc., are not formed, and cuprous oxide scales can be smoothly dissolved as cupric ion. As a result, etching is smoothly and stably carried out, and a clear etched surface is obtained. The gaseous oxygen is supplied to the etchant 2 immediately before the etchant 2 is sprayed. Accordingly, the gas unneeded by the dissolution reaction in etching is discharged into the atmosphere simultaneously with the spraying of the etchant. As a result, the unneeded gas is not mixed into the etchant 2 to be circulated and used, the function of a pump is not deteriorated, and the etchant 2 can be stably circulated and sprayed.

Inventor: YAMAMOTO TETSUICHIRO
IPC: B41J2/27
Filed: 1986-11-07
Abstract: PURPOSE:To reduce noise, by utilizing displacements generated by a shape memory alloy, controlling energization time for heat generating resistors, and using a cooling effect based on Le Chaterlier's law. CONSTITUTION:The temperature inside a radiating container 7 is detected by a temperature sensor 9, energization time for electrodes 4 is controlled according to a signal from electrodes 8, and a heat generating resistor 3 is caused to generate heat, thereby heating a shape memory alloy at a wire-driving part 3. When the temperature of the alloy reaches or exceeds a displacement temperature, a wire part is caused to strike an ink ribbon 11, thereby printing on a recording paper 12. At this time, a valve 6 is in an opened state, so that an internal gas 10 and an external gas can be freely circulated, thereby preventing the temperature inside the container 7 from rising. Next, the energization of the electrode 4 is stopped, the valve 6 is closed, the container 7 is hermetically sealed, and a valve 5 is simultaneously opened to instantaneously perform forced decompression of the internal gas 10, whereby the gas 10 is cooled. Then, a shape memory alloy at a wire-driving part 1 is cooled, and when the temperature of the alloy is lowered to or below the displacement temperature, the wire part 2 is separated from the ink ribbon 11, and is returned to a non-printing condition. The valve 6 is then opened to be returned to a stand-by state. With this system, noise and power consumption can be reduced.
