IPC: F01N1/08
Filed: 1988-04-26
Abstract: PURPOSE:To especially reduce the exhaust sound of a low frequency component by arranging a control valve of an exhaust main pipe and branch pipe and closing the downstream side of the branch part of the exhaust main pipe by the control valve at the time when the number of engine revolutions is lower than the specified value. CONSTITUTION:A control valve 7 is arranged at the branch part 5 of an exhaust main pipe 1 and a branch pipe 4. The control valve 7 is connected to an actuator 9 via a wire cable 8. The actuator 9 is connected to the control circuit 10 in which the rotary pulse signal of an engine is input. Namely the control valve 7 controls via the actuator 9 by the control circuit 10 according to the number of the engine revolutions. In this case, at the time when the number of the engine revolutions is lower, for instance, than the specified value, the downstream part 1B of the branch part 5 of the exhaust main pipe 1 is closed by the control valve 7. One muffler system is thus formed by the upstream part 1A of the branch part 5 of the exhaust main pipe 1 and branch pipe 4 and the exhaust sound of a low frequency component is especially reduced.

IPC: B24B49/00
Filed: 1979-08-16
Abstract: PURPOSE: To measure relative change of residual stress in a short time by observing change in the figure of cutting marks on a work under continuous processing by frequency analysis.  
     CONSTITUTION: When laser beam 10 is applied to cutting marks on a work 12, the reflected beams produce a Fraunhofer diffraction pattern 10. This pattern 10 is a product of the Fourier conversion of microstructure on the surface of the work 12, and measuring the intensity distribution on the pattern 10 implies frequency analysis of this microstructure. The residual stress can be determined by analyzing the pattern 10 with the aid of a known relation between the microstructure on a cut surface and the residual stress due to surface processing. The diffraction pattern 10 is fed in a subtractor 16 through photoelectric transducers 13A, 13B amplifiers 14, 15 to obtain the relation of the residual stress to the amount of processing.
