Abstract: PROBLEM TO BE SOLVED: To produce a polypropylene-based resin foamed product containing conductive carbon and having a high compression strength and a low surface resistivity. SOLUTION: This conductive polypropylene-based resin foamed molded article is produced by charging polypropylene-based preliminarily foamed grains containing conductive carbon in an amount of 5-20 wt.% into a mold, and then heating the charged grains with steam at a steam temperature which is not lower than a low temperature melting peak temperature and not higher than a boundary temperature between the two melting peaks. The polypropylene- based preliminarily foamed grains satisfy the inequality: 0.25<=α/(β+α)<=0.60. Therein, β [J/g] is the heat of fusion of the first endothermic peak based on the original crystal state of the base resin in a DSC curve obtained by the use of a differential scanning calorimeter, when heated from 40 to 220 deg.C at a heating rate of 10 deg.C/min, and α[J/g] is the heat of fusion of the second endothermic peak appearing on the higher temperature side of the first peak.

IPC: H01H50/08
Filed: 1992-12-25
Abstract: PURPOSE:To provide a method capable of easily judging contact consumption regardless of the operating state of an electromagnetic contactor in a contact consumption display device for electromagnetic contactor.

Abstract: PROBLEM TO BE SOLVED: To warm a potentially dangerous road surface by warning a driver that the road surface has a different frictional characteristic when an absolute value exceeds a prescribed value in comparison of the difference in a difference between present speed ratios and a difference between previously stored speed rations. SOLUTION: Four wheel speed values S1-S4 representing instantaneous speeds of respective wheels are fed into an arithmetic process unit 1.

After that, a total process is repeated where a wheel speed is sampled, the speed ratios of right and left wheels are calculated, a difference between the right and left speed ratios is derived, and this new differential valve is stored. The newest differential value is compared with the previously stored differential value, and when absolute size of any differential value of these differential values exceeds a prescribed value, a system commands an alarm unit 2 to generate an alarm.
