Title: Soldering method and apparatus
Inventor: ITOH TAKAHIRO
IPC: B23K1/00
Filed: 1998-06-09
Abstract: Method and apparatus by which relative displacement between molten solder and a terminal pin is caused and a coating formed on an end portion of a coil on the terminal is removed by the molten solder, and thus the terminal portion is firmly soldered to the terminal pin after removal of the coating.  In contrast, in conventional soldering methods, when a terminal pin, which is provided on a terminal base and has an end portion of a coil wound therearound, is dipped in molten solder contained in a solder bath, there is no relative displacement between the pin and the molten solder.  Thus, sometimes the coating formed on the coil still remains, so that a complete soldering connection between the terminal pin and the coil is not sufficiently achieved.  In accordance with the method and apparatus of the present invention, a full connection therebetween is achieved, and the reliability thereof is enhanced.

Filed: 1997-05-30
Abstract: In a device for producing sponge iron from lumps of iron oxide in a reduction shaft (1), a hot, dust-containing and carbon monoxide-rich reduction gas is used. The reduction gas is generated in a gas generator by partial oxidation of solid carbon-containing materials and is in part supplied to the reduction shaft through several lateral reduction inlets (3) arranged at the same height around the circumference of the reduction shaft at the lower end of the reduction zone. The lumps of iron oxide are introduced into the reduction shaft through its top area and discharged as sponge iron at its bottom end. Additional reduction gas inlets (15) shaped as downwardly open channels (11) which extend from the outside to the inside of the reduction shaft and/or shaped as ducts which extend obliquely downwards from the outside to the inside of the reduction shaft and have open inner ends are arranged below the plane of the lateral reduction gas inlets. Reduction gas may thus be also supplied to the radial inner area of the reduction shaft, so that the introduction of dust by the reduction gas is not limited to the outer area of the bulk material in the reduction shaft.

Patent CA-2260883-A1 (CA)
Inventor: COOPER ALBERT B
IPC: H03M7/46
Filed: 1997-07-23
Abstract: A dictionary based data compression and decompression system where, in the compressor (10), when a partial string W and a character C are matched in the dictionary (13), a new string is entered into the dictionary with C as an extension character on the string PW where P is the string corresponding to the last output compressed code signal. An update string is entered (113) into the compression dictionary for each input character that is read and matched.  The updating is immediate and interleaved with the character-by-character matching of the current string. The update process continues until the longest match is found in the dictionary. The code of the longest matched string is output (106) in a string matching cycle. If a single character or multi-character string "A" exists in the dictionary, the string AAA...A is encoded in two compressed code signals regardless of the string length. This encoding results in an unrecognized code signal at the decompressor. The decompressor (40), in response to an unrecognized code signal, enters (Fig. 8) update strings into the decompressor dictionary (43) in accordance with the recovered string (161) corresponding to the previously received code signal, the unrecognized code signal, the extant code of the decompressor and the number (135) of characters in the previously recovered string.
