摘要:
Disclosed herein is a structure for preventing current from leaking out of devices such as a valve, an intermediate reservoir, etc., which are employed in an electrostatic spray coating apparatus for applying a desired voltage to electrically conductive paint so as to electrostatically spray-coat a workpiece therewith. The current-leakage prevention structure basically comprises any one of the devices each made of an electrically-conductive material, a container made of an insulating material, which accommodates the device therein and has a paint passage defined therein capable of communicating with the device, and a cover for externally covering the container. A creepage distance defined by the container and the cover is set to reach a desired creepage length or more capable of preventing current leakage. It is therefore possible to reliably prevent current from leaking even when a high voltage is applied to the devices.

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-atom 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 keto group. Such compounds being useful as insecticides.
