IPC: F02B1/04
Filed: 1982-06-07
Abstract: PURPOSE:To improve firing capability and stain resistance of a plug and reduce its radio noise, by mounting a metal fitting of the spark plug to be electrically insulated to a combustion chamber of an internal-combustion engine. CONSTITUTION:A heat resistant and electrically insulated cylindrical bush 8 is screwed to a mounting threaded part (p) of a mounting metal fitting (d) of a plug 4, and electrodes (e), (f) are electrically insulated from a body of a vehicle. Further a heat resistant and electrically insulated plug cap 7 is mounted to an insulator (b) of the plug. When ignition is performed, plus voltage is applied to a center electrode of the spark plug 4 while minus voltage of reverse polarity is applied to the side electrode (e), in this way, as voltage at an electric discharge is decreased to a half level, required insulation breakdown voltage of parts can be reduced, while consumption of the plug due to overheat is decreased and a sufficient thermal value is ensured, accordingly firing capability can be improved and a raido noise can be reduced.

Abstract: PURPOSE:To improve the testing efficiency and allow the operating ratio of a robot to be improved simultaneously by providing the tester with both two fitting tables for a printed circuit base board and two magazines so as to have the robot feed the printed circuit board for testing one after the other. CONSTITUTION:A robot takes a printed circuit base board 1-1 out of a magazine 6 allowing it to move to a fitting table 8 of a tester 4 and to be fitted. While the printed circuit board 1-1 is being tested, the robot is allowed to take the printed circuit board 2-1 out of a magazine 7 allowing it to be fitted on another fitting table 9. After the test for the printed circuit board 1-1 has been completed, the test for the printed circuit board 2-1 which has already been fitted on the fitting table 9, is started. Simultaneously, the printed circuit board 1-1 which has been tested already, is taken back to the previous place of the magazine 6 by the robot. Subsequently, the robot takes another printed circuit board 1-2 out of the magazine 6 allowing it to be fitted on the fitting table 8. Thus, this configuration allows the printed circuit board to be fitted on the fitting table while the other printed circuit board is being tested on another fitting table permitting the printed circuit board to be ready for test at all times so as to improve the testing efficiency.

Abstract: PURPOSE:To simultaneously determine arsenic and antimony and to shorten the time for an analysis by simultaneously generating the hydrides of the arsenic and antimony by a prescribed procedure and subjecting the same to a fluorescent X-ray analysis. CONSTITUTION:A copper base metal is decomposed by nitric acid and aq. ammonia and nitric are added to this soln. The concn. of the nitric acid is then adjusted and a potassium permanganate soln. is added to the soln. This soln. is heated to co-deposit the arsenic and antimony which are recovered by using filter paper. Sodium hydrogen sulfite is added as a sulfuric acid type soln. thereto to reduce As<5+> and Sb<5+> respectively to As<3+> and Sb<3+>, to which sandy zinc is added to simultaneously generate the hydrides of the arsenic and antimony. These hydrides are captured by filter paper impregnated with silver nitrate and are subjected to the fluorescent X-ray analysis. The quantities of the arsenic and antimony are simultaneously determined and analyzed when the results of the analysis are referred to a previously formed calibration curve. The time for the analysis is greatly shortened as compared to the case in which the arsenic and antimony are separately generated.
