Patent EP-0507006-A1 (EP)
Inventor: ISHIBASHI TADAYA
IPC: C23G1/32
Filed: 1991-12-23
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. The mixture liquid of the overflows from the respective tanks and the washing water for removing the foreign matters in the salt bath is mixed with the nitric acid-containing liquid for pickling the steel material and then sodium hydroxide is supplied to alkalize. Thus, the dissolved metal compounds in the liquids, which have been used for the treatment, are separated into the insoluble solid metal hydroxides and the liquid of the soluble salts without mixing the insoluble alkalies.

Abstract: An East-West switching transistor (Q1) is coupled between a flyback transformer primary winding (W1) and a horizontal deflection output transistor circuit (100) to control retrace energy to obtain an East-West modulation of the deflection current amplitude (i3) as required for East-West pincushion raster correction. The East-West switching transistor isolates a retrace resonant circuit (100) that includes a horizontal deflection winding (LH) from a flyback resonant circuit (251) that includes the flyback transformer (W1) during a portion of retrace. The deflection winding (LH) is coupled to a common conductor (GROUND) to permit the use of a retrace voltage sample (V4a) developed in the deflection winding as a feedback signal to synchronize the deflection current to the video signal (H s ). The arrangement reduces phase modulation of the deflection current as a function of beam current (i BEAM ) variations, that could be visible as a beam current dependent horizontal picture shift or a raster bending in a horizontal direction.

Abstract: The invention relates to a time division multiplex transfer system and a coupling element for an asynchronous time division multiplex transfer system, which transmits cells supplied by feeding lines (14a to 14d) and destined for a serving line (10), which contains cell filters (11a to 11d) which are coupled in each case with one feeding line and which, when the route identifier contained in the cells is assigned to the serving line, allow the cells to pass through to be stored in intersection buffers (12a to 12d) which are coupled with each cell filter, and which contains an allocation circuit (9) to control the process of reading out the cells from the intersection buffers to the serving line. The allocation circuit contains a chain of hierarchically structured allocation elements (13a to 13d) assigned to each intersection buffer, in each case having one control buffer (17a to 17d). When a cell is stored in the assigned intersection buffer, each allocation element stores a first state in the assigned control buffer and the hierarchically lower allocation elements store a second state in the assigned control buffers. In reverse hierarchical order, each allocation element evaluates the assigned control buffer and, if a first state is present, releases the assigned intersection buffer for read-out of a cell. …<IMAGE>…

Abstract: 5 n7 A process for the preparation of hydrocarbons comprises feeding a mixture of hydrogen and carbon monoxide into a reaction zone in a reactor at an elevated temperature and pressure and allowing the hydrogen and carbon monoxide to react in the presence of a catalyst retained in the reaction zone, and is characterized in that a reservoir of a hydrogen-rich gas is maintained at a pressure above that of the pressure of the feed mixture the reservoir and the reaction zone being connected in such a way that hydrogen-rich gas can flow from the reservoir into the reaction zone. A reactor in use in the process is shutdown by interrupting the feed of the mixture of hydrogen and carbon monoxide, thereby allowing hydrogen-rich gas to flow from the reservoir and quench the reactions occurring in the reaction zone. Apparatus for use in the process comprises a reactor having a reaction zone in which catalyst can be retained; an inlet for introducing at elevated pressure a feed gas from a feed gas supply into the reaction zone; means for interrupting the flow of feed gas to the reaction zone from the feed gas supply; storage means for maintaining a reservoir of hydrogen-rich gas at a pressure above that of the feed gas; connection means extending between the storage means and the reaction zone by which hydrogen-rich gas can flow from the reservoir into the reaction zone whilst the flow of feed gas is uninterrupted.

Abstract: A semiconductor light amplifier (12) is driven by a drive device (14), and is arranged selectively to amplify a TM mode component or a TE mode component of input light. For example, TE mode light is selectively amplified by making the thickness of the active layer of the semiconductor light amplifier not more than 0.05 µm, or by tilting at least one of the entrance and exit faces of the amplifier by 10 to 16 degrees or the Brewster angle. As another type of light amplifying polarizer, input signal light and excitation light are combined by a half mirror (50) or an optical coupler (54), and combined light is input to a rare-earth element doped, polarization maintaining optical fiber (46).

Abstract: A method of moving the nozzle of a CNC laser beam machine, which performs three-dimensional working, with respect to a surface to be worked. A hand coordinates system comprising a plane extending along the nozzle axis and that perpendicular to the nozzle axis is provided and a command of movement in said system is outputted with the use of a machine operating board (31). Matrix forming means (38) generates a conversion matrix for converting the hand coordinates system to a basic coordinate system from information (39a, 39b) on rotational positions of the axes α and β indicating an attitude of the nozzle. Coordinates converting means (37), while using said conversion matrix, converts movement commands (Δxh, Δyh, and Δzh) into movement amounts (Δx, Δy, and Δz) in the basic coordinates system for moving the nozzle. Thus the nozzle can easily be moved without changing the distance between the nozzle and the surface to be worked. The distance between the nozzle and the work can be adjusted with the nozzle moved perpendicularly to the surface to be worked.
