Title: Driving method of liquid crystal maker
Inventor: ICHIHARA MASASHI
IPC: B23K26/00
Filed: 1994-02-08
Abstract: PURPOSE:To heat up a liquid crystal and to shorten image rising time by this heating up by irradiating the light non-transmissive surface of a liquid crystal mask with a laser beam before completion of image rising. CONSTITUTION:A controller 17 drives a scan mirror of a first polarizer in such a manner that a heating target line is irradiated with the laser beam. Next, the laser heating target line is irradiated with the laser beam while the laser beam is moved back and forth in this target line in an X direction by rotation of a polygon mirror when a laser oscillator l is pulse oscillated by a Q switch. This irradiation is executed before voltage for image display is applied after the laser beam is set at the irradiation position to the heating target line by driving of an optical system. The liquid crystal electrode generates heat by absorbing part of the laser beam when the liquid crystal mask is irradiated with the laser beam. The generated heat transfers the liquid crystal electrode and diffuses to the liquid crystal mask 8, thereby heating up the liquid crystal. The voltage for display of the image 82 is applied to the liquid crystal mask 8 at this time. (Namely, the rise of the image is started). The mask is raster irradiated with a first polarizer and the image (a) is marked when the rising of the image (a) is completed.

IPC: G21F9/08
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To stably and easily dispose of a radioactive waste liquid generated from a radioactive substance handling facilities over a long period. SOLUTION: Ozone is supplied to a radioactive waste liquid containing organic substances generated from a unclear power plant. The organic substances are decomposed into carbon dioxide and water through the effect of the ozone H2 SO4 is added to the radioactive waste liquid containing the carbon dioxide and the water generated by the decomposition to control the pH of the radioactive waste liquid to 7. The carbon dioxide is separated as an exhaust gas from the radioactive waste liquid by such a pH controlling. The carbon dioxide contains C-14. After the radioactive waste liquid clear of C-14 is concentrated it is poured into a drum and is solidified by cement. As the radioactive waste liquid does not contain C-14 any more, it can be stored stably and easily in burial facilities.
