Title: Unusual sound prevention bellows used in exhaust system of engine
Inventor: YOKOTA TAKESHI
IPC: F01N1/12
Filed: 1994-10-26
Abstract: PURPOSE: To prevent the occurrence of resonance sound by forming a helical plate for revolving exhaust air in a whirlpool shape toward the inside of an entrance port for a bellows in such a way that its helical surface is formed into a specified direction. CONSTITUTION: A entrance side connecting pipe 3 is integrally formed with the bellows pipe section 1 of a bellows at its front end, and a helical plate 4 is fixed at the inside of the connecting pipe 3. The helical plate 4 has a helical surface of four pitches formed in the center axial direction of the bellows, and has the helical surface fixed on the inner wall of the connecting pipe 3 by an appropriate supporting means. When exhaust gas flows in from its upstream as indicated by a sign f1, and arrives at an entrance port P, it is turned out a revolving flow f2 flowing toward its downstream while being guided by the helical surface of the helical plate 4, and it is hit against each vertical wall 1a of the bellows pipe section 1 obliquely in the circumferential direction.  The flow of the exhaust gas does not cause air within the recessed space 1b of the bellows pipe section 1 to be resonant, but causes a great number of the vertical walls 1a of the bellows pipe section 1 to be unequally oscillated, so that the occurrence of resonance is thereby prevented. Thus as mentioned above, the occurrence of resonance sound can thereby be prevented.

A current, which is made to flow in the group A1 from the first voltage Vcc, is consumed by the group A1 and after that, it is used by the group A2. When the total load capacity of the first group A1 and the total load capacity of the second group A2 are distributed almost equally, the power consumption PD2 of the whole chip is equal with one in the case where the first voltage Vcc itself is reduced to 1/2XVss and the effect of a reduction in the consumption of power due to a reduction in an amplitude is increased. Thereby, a reduction in the consumption of power as seen from the whole chip is contrived.
