    • PROBLEM TO BE SOLVED: To provide a laser processing machine useful for improving yields of industrialized production by effectively removing dust by making use of the gravity to avoid erroneous wiring.SOLUTION: The laser processing machine includes a chamber, a laser system, at least one processing platform, and at least one upper motion platform. The laser system is provided at a lower part inside the chamber, and used for outputting a laser beam whose traveling direction is opposite to the gravity direction. The processing platform is provided at an upper part inside the chamber, and includes a suction surface and a connection surface facing each other. The suction surface is located below the connection surface, and is used for sucking a workpiece. The upper motion platform is provided at the upper part inside the chamber, and is connected so as to correspond to the connection surface of the processing platform in order to cause the processing platform to move.

    • 1395261 Polypeptides C H LI 27 April 1972 [27 April 1971 15 July 1971] 19542/72 Heading C2C Polypeptides having growth promoting activity are prepared by (a) polypeptide chain linking one of the following unbridged chains-: (i) the polypeptide chain having the sequence of residues X to 190 (1#X#86) shown in Fig. 2, (ii) the polypeptide chain having the sequence of residues shown in Fig. 3, (b) generating in a manner known per se, sulphhydryl groups on the cysteine residues and (c) submitting the polypeptide chain of step (b) in solution or suspension to the action of an oxygen-containing gas thereby forming disulphide bridges between the cysteine residues, under the following conditions:- (i) in the presence of an oxidizable material different from the polypeptide, the concentration being not more than 200 mgs. of oxidizable material per 100 mgs. polypeptide; (ii) the concentration of polypeptide being at least 0À01 mg. per ml. of solution; (iii) at a pH of 4À5 to 9À0 and (iv) at a temperature of not less than 0‹ C.; thereby forming at least one intramolecular ring in the polypeptide chain. The products thus produced may be reacted (a) with 2-hydroxy-5-nitro-benzyl bromide or 2-nitrophenylsulphenyl chloride to give derivatives having a 2-hydroxy-5-nitrobenzyl or 2- nitrophenylsulphenyl radical substituted in the tryptophan residues or (b) with tetranitromethane to form a derivative with NO 2 groups substituted in those tyrosine residues which are nitratable with tetranitromethane. The products may also be reduced, thus converting the disulphide bridges to sulphhydryl groups, and the reduced polypeptide reacted with iodoacetamide to form a derivative having 5- carbamidomethyl radicals substituted in each cysteine residue. The polypepetides prepared as described above are claimed per se. Polypeptides shown in Fig. 1, which have been treated with 2-hydroxy-5-nitro-benzyl bromide, 2-nitrophenylsulphenyl chloride or tetranitromethane, or which have been reduced and then treated with iodoacetamide to form appropriate derivatives are prepared in a similar manner to that described above and are also claimed per se.

    • The presented invention is to provide a system of QS-CDMA with two-level spreading scheme and LS sequences, the said system comprising: means for designating a user in the system to a user group according to the cell or the sector it belongs to; means for spreading the information signals both by the FL and SL spreaders; one-level despreading means coupled to the said means to simplify the receiver structure of the two-level spreading system; means for communicating information signals between users in the same user-group without MAI; means for communicating information signals between users in different user-group with suppressed MAI; means for employing the LS sequences as the spreading sequences so as to suppress the MAI. The presented invention can obtain satisfactory system error performance and system capacity.
    • 本发明提供一种具有两级扩频方案和LS序列的QS-CDMA系统,所述系统包括:根据所属小区或其所属扇区将系统中的用户指定给用户组的装置; 用于通过FL和SL撒布机传播信息信号的手段; 耦合到所述装置的一级解扩装置,以简化两级扩展系统的接收机结构; 用于在没有MAI的同一用户组中的用户之间传递信息信号的装置; 用于在具有抑制的MAI的不同用户组中的用户之间传递信息信号的装置; 用于采用LS序列作为扩展序列以便抑制MAI的装置。 本发明可以获得令人满意的系统误差性能和系统容量。
