摘要： A method of processing a photosensitive glass includes exposing. Photosensitive glass by radiation from a laser whose oscillation wavelength lies within the range of wavelengths of exposing light to which the glass responds. Then, the exposed portions 1c are thermally developed and etched. Since a laser beam propagates with a high rectilinearity, the front and rear surfaces of thick photosensitive glass can be exposed without producing dimensional errors. Therefore, the etching accuracy is improved. Especially, where the front and rear surfaces of photosensitive glass are etched, both surfaces can be processed so as to form the same shape in them accurately. In addition, because almost all the energy of the laser radiation is used for exposure of the photosensitive glass, the energy is not wasted and so the efficiency is high.

摘要： A structure for an ink jet head comprising: an ink passage adapted to be supplied with ink; a nozzle communicating with the ink passage and positioned to have exit deep from the end face of the ink jet head; a hollow portion formed in the head end face to communicate with the nozzle exit and to have a larger diameter than the nozzle; and ink ejecting means disposed to correspond to the ink passage and energized electrically to eject the ink in the ink passage out of the nozzle end face through the hollow portion. As a result, the ink droplets can always be ejected in a correct direction by suppressing the fluctuation of their flowing direction, which might otherwise be caused by the breakage in the periphery of the opening in the head end face or by the ooze of the ink. Thus, the ejection characteristics are uniformed by absorbing the errors due to the cutting or grinding step.
