Abstract: The present invention provides an apparatus and method for controlled release of a fumigant into a wooden structure to prevent decay of that structure. According to the present invention, a fumigant in an ampule or container is inserted into the wooden structure. The ampule or container is made of a polymeric material that does not react with the fumigant, but having walls which are permeable to the fumigant such that, when inserted into the wooden structure, the rate of release of the fumigant through the walls of the ampule is slow enough to continuously treat and arrest decay of the wooden structure, particularly decay caused by fungi, over extended periods of time (i.e., 1, 5, 7, 10, 15, 20 or 30 years). The rate of release of the fumigant can be controlled by the type of fumigant, the shape of the container, the specific polymer used to make the container, and by the thickness of the container wall.

Abstract: A packaging tape includes a carrier tape and a top tape. The carrier tape is provided with device-accommodating recesses. The top tape is attached to the carrier tape by heat-sealing to close the device-accommodating recesses. The carrier tape includes a resin layer made by impregnation and drying of a water-dispersible resin or a water-soluble resin or both. The top tape is attached to the resin layer of the carrier tape. This prevents the generation of static electricity on the top tape as the top tape is peeled off the carrier tape. Accordingly, the unscheduled removal of electronic devices from the device-accommodating recesses by the static electricity is avoided.
