Title: Method for reducing volume of foamed polystyrene
Inventor: TANAKA SHINGO
IPC: B09B3/00
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To reduce the volume of recovered foamed polystyrene at a low cost by dissolving the foamed polystyrene in a binary organic solvent comprising a glycol ether compound and n-hexane. SOLUTION: The glycol ether compound is exemplified by ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monoisopropyl ether or diethylene glycol monomethyl ether. It is desirable that the rate of the n-hexane used in the organic solvent is 9-98 vol.% when ethylene glycol monomethyl ether is used, and it is 9-91 vol.% when diethylene glycol monomethyl ether is used. The reduction of volume of polystyrene can be effectively performed when the rate of the n-hexane used falls within this range. According to this method, waste foamed polystyrene can be reclaimed without deterioration in quality and can be treated at a low cost in both cases irrespectively of its amount.

Abstract: PROBLEM TO BE SOLVED: To make it possible to diagnose the state of the degradation of a laid cable by a method wherein a sheath material on the laid cable is irradiated with light, elastic waves which are propagated in the sheath material are detected and a detected result is analyzed. SOLUTION: A sheath material 8 on a cable 1 is irradiated with single or intermittent light 2 at a short cycle, its heating operation and its cooling operation are repeated locally, and elastic waves 3 are generated so as to be propagated in the sheath material 8. The elastic waves are detected by a sensor 4, their waveform is amplified and shaped by a detecting device 6, and the waveform is analyzed by an analytical device 7. Since the elastic waves 3 are changed due to the state of the degradation of the sheath material 8, the state of the sheath material is known by the state, and the degradation of the cable 1 is diagnosed. The degradation of the cable 1 is compared with the initial characteristic of the elastic waves at the sheath material 8 before its degradation, and the degradation can be diagnosed.  By this method, the state of the degradation of the cable 1 can be diagnosed nondestructively, and the method is useful for the maintenance and the inspection of the cable 1.
