The polishing apparatus includes a polishing table having a polishing pad, a top ring, and a substrate escape detection section for detecting escape of the substrate from the top ring. The detection section includes a light irradiation member for irradiating an area of the upper surface of the polishing pad with light, a controller for controlling the light irradiation of the light irradiation member, an image-taking member for taking an image of the area irradiated with the light, and an information processing member for processing information outputted from the image-taking member. The controller controls the light irradiation member in such a manner that it performs light irradiation at least for a period of time during which the substrate is regarded as being in contact with the polishing pad.

Abstract: A liquid filling nozzle plate is formed from a plate member provided with a plurality of through-holes. The liquid filling nozzle plate is attached to the lower end opening of a liquid filling tube of a liquid filling device. Liquid filling the liquid filling tube is prevented from flowing out of the tube and plate by surface tension in the through-holes of the liquid filling nozzle plate. The inner peripheral surface of each through-hole is provided with a circumferential projection projecting in a direction in which the inner diameter of the through-hole is reduced. The resulting cross-sectional configuration of the through-holes increases the surface tension of the through-holes to effectively prevent dripping of liquid from the through-holes. Dripping of liquid from the through-holes can also be prevented by providing through-holes having an elongated slit-shaped opening configuration.

Abstract: In an electrolyzer provided according to this invention, the polarity of electrodes is periodically inverted at very short intervals. This has the effect of allowing gases to be generated uniformly all over the surface of each electrode in the form of extremely small bubbles instead of being formed in specific positions in the form of large bubbles as is the case with a conventional electrolyzer in which a direct current is allowed to flow without changing the flow direction. Thus the surfaces of electrodes are prevented from being covered with bubbles, and the flow of liquids along the surfaces of electrodes is not disturbed by the bubbles any more.

Abstract: The present invention relates to the method of treating the salt bath liquid. In the surface treatment of the steel material by the use of the high-temperature salt bath mainly comprising sodium hydroxide and sodium nitrate, the salt ingredients contained in the washings generated are separated to be recovered and the metal salts contained are separated in the form of the insoluble salts. The salts contained in the nitrate radical-containing liquid system are recovered as the free acids again, the alkalies being recovered, and the reagents contained in the overflow from the salt-washing tank being recovered. The anode chamber liquid generated in the recoverying operation of the reagents is returned to the washing tank again to increase the concentration of the salts. The anode chamber liquid is poured into the pickling tank to reduce the oxidizing soluble metal salts contained in the washings by iron within the pickling tank, whereby the oxidizing soluble metal salts are insolubilized.

Abstract: The present invention relates to an electrolyzer for treating an object liquid. A cylindrical anode plate is formed as an outer wall of said electrolyzer and a cylindrical cathode plate is coaxially arranged at a position close to an inner surface of said anode plate. An ion exchange membrane is coaxially arranged between both electrodes to form an isolating chamber for a selective electrophoretic separation and removal and a concentration. A liquid, which has been subjected to an aimed treatment in said isolating chamber, is uniformly flown out from a whole circumference through a circumferential passage provided in an upper portion of an electrode portion. Thus, anions, which have acted upon metal cations, are dissociated in said isolating chamber to selectively separate merely cations.
