Abstract: An intumescent firestop device having a layer of non-curing moldable two-stage intumescent composite and a restraining layer. When the firestop device is installed around a pipe near the wall opening through which the pipe runs, the intumescent composite exudes into the annular space between the pipe and the wall opening thereby forming a cold-gas seal. The composite is a two-stage intumescent composite that contains two different intumescent components that begin to intumesce at two different temperatures to form a hard char.

Abstract: An optical recording medium formed from a transparent substrate, an enhancement layer formed on the substrate, a guide layer, an interference layer, a recording layer, a protective layer, and a reflective layer. A recording region is formed on the guide layer by etching to a predetermined spiral or a coaxial circular pattern. Because the enhancement layer is formed from a compound of aluminum such as Al.sub.2 O.sub.3, it is not etched during plasma etching using a gas mixture of carbon tetrachloride and oxygen. Therefore, the recording region remains smooth and noise generated by roughness between layers can be prevented. By making the thickness of the guide layer 20 nm or more, light which passes through the guide layer and which generates multi-layer interference between the recording layer and the reflective layer is reduced and the amount of reflective light is increased, Therefore, fluctuations in the pushpull signal by the fluctuations in the thickness of the guide layer is reduced.

The label is attached to an object to prevent the object from being stolen or taken without permission. An object, such as food goods, having such an antitheft label can be thawed or heated in a high-frequency heater such as a microwave oven without developing spark discharge at edges of the soft magnetic metal strip of the label, thereby preventing the occurrence of fire damage to the food product.
