    摘要: Nitro-substituted heterocyclic compounds of the formula (I) ##STR1## wherein R is hydrogen or alkyl,Z is an optionally substituted aryl or optionally substituted heterocyclic groun containing at least one atom selected from N, O and S,A is optionally substituted ethylene or optionally substituted trimethylene, andB stands for 2 or 3 members of a heterocyclic ring which is formed, together with the adjacent C-atom and N-aom and at least one of said members may represent a hetero atom and may be optionally substituted, provided that when B stands for 3 members, two of which are carbon atoms and the other one is a nitrogen atom which is located in the middle of the three members, then at least one of said two carbon atoms must be substituted by a xeto group. Such compounds being useful as insecticides.

    摘要: A leaf panel bundling apparatus allows leaf paper to be bundled to be inserted into the apparatus from either the front or the top of the apparatus. The leaf paper bundling apparatus wraps a tape around many leafs of paper which have been stacked, uses a cutter to cut the wrapped tape and uses a thermo-adhesion head to adhere the ends of the tape to one another so as to bundle the leaf paper. A leaf paper insertion opening portion has a slit extending to a location above the front portion of the main apparatus unit and into which leaf paper can be inserted from the front or top of the apparatus. A leaf paper regulation device receives a leaf paper lower edge and a leading edge which is the edge to be located furthest from the front of the main apparatus unit after insertion. A tape supply device supplies tape to be wrapped around the periphery of the leaf paper, applies tension to and tightens the wrapped tape. A tape winding device has an arm which can hold an end of the tape fed from the tape supply device and can orbit from a standby position to wrap the tape around the leaf paper. A leaf paper holding device is also provided to facilitate the tightening of the wrapped tape and holds the leaf paper to both sides of the tape in the direction of the width of the wrapped tape.
