Title: Method for removing dissolved carbon dioxide in pure water producing apparatus
Inventor: USHIGOE KENICHI
IPC: C02F1/20
Filed: 1986-07-21
Abstract: PURPOSE:To remove a dissolved carbon dioxide in water at a high rate by dividing a reverse osmosis device to two stages, permitting the permeation of the carbon dioxide in a 1st stage, converting the dissolved carbon dioxide to anion form by pH adjustment in a 2nd stage and removing said gas by executing a reverse osmosis treatment. CONSTITUTION:After raw water 1 contg. the free carbon dioxide is subjected to reverse osmosis, said water is subjected to an ion exchange treatment by which pure water is produced. The treatment is executed by using the reverse osmosis device 6 which removes the hardness component in the raw water at a high rate for the 1st stage of said reverse osmosis treatment. The pH of the permeated water is adjusted to an alkali side by adding an alkali agent to waid water and if necessary, an extremely slight amt. of a scale preventive agent (e.g., polyphosphate) is added thereto. The treatment to remove the carbon dioxide component converted to bicarbonate ions and carbonate ions in the above-mentioned manner is executed by using the 2nd stage of the reverse osmosis device 20. As a result, the dissolved carbon dioxide in the water is removed at a high rate prior to the execution of the ion exchange treatment.

Abstract: PROBLEM TO BE SOLVED: To suppress increase in resistivity of an electrode by forming a region for blocking intrusion of ions into a semiconductor layer at the time of ion implantation on the semiconductor layer side of the electrode. SOLUTION: An oxide 11 is deposited on a silicon semiconductor layer 10 and a crystalline silicon 12 is deposited thereon. The deposition temperature is set low, at first, to bring about amorphous state 12a and then it is set at a high level to cause polycrystallization 12b. The amorphous part 12a is then polycrystallized by annealing to produce a polycrystallized part 12c. More specifically, a region 12c having large crystal grain size is formed on the surface side of a polycrystalline gate electrode 14 while a region 12b having small crystal grain size is formed in a region on the semiconductor layer 10 side in order to block intrusion of implanted ions into the semiconductor layer.

Abstract: PURPOSE:To easily remove dirt, etc., sticking on the external end surface of a lens by forming cuts part in a ferrule so that at least part of the external end surface of the lens is open to the outside in its in-surface direction. CONSTITUTION:The tip part of the ferrule 1 is removed nearly equally at three parts of the ferrule outer periphery to the external and surface 56a of the lens 56 to form the three cut parts 2 - 4, which have three surfaces 2a - 4a in level with the external end surface 56a of the lens. The exposed part of the external end surface 56a of the lens 56 becomes large to make the dirt on the lens surface easy to remove, and the lens external lens surface 56a is open to the outside at the cut parts 2 - 4 in the in-surface direction, so cleaning liquid or gas which is jetted strongly from the front surface side of the ferrule 1 for lens surface cleaning is discharged smoothly in the in-surface direction. Consequently, the dirt is removed reasonably even from the corner parts 1a where dirt is easy to stay and hard to removed and the efficiency of the cleaning operation for the lens external end surface 56a is improved.
