Title: Elliptical muffler
Inventor: IKEDA MASAHIRO
IPC: F01N1/00
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To reduce occurrence of emission noises caused by the vibration of an outer plate, and diminish air resistance. SOLUTION: The upper surface view of the muffler main body 11 of an elliptical muffler 10 is formed into a circular shape or an elliptical shape, and the cross sectional shape thereof is formed into the elliptical shape. Hereby, a flat surface part does not exist on the outer plate 15 of the muffler main body 11 and stiffness is enhanced therefore, occurrence of vibration can be reduced. Therefore, emission noises caused by the vibration of the outer plate 15 can be reduced. The height of the muffler main body 11 is low and ventilation resistance is few, thus a cooling air flow is smoothened and cooling efficiency can be improved.

Filed: 1989-12-28
Abstract: PURPOSE: To switch a current source for supplying a current by providing a switching circuit for setting a second current source to an inoperative state in a first mode and setting a second power supply to a current supply state 111 a second mode. CONSTITUTION: When logic signals S1 are low (first mode,) the current does not flow to a TR T20 . Since a differential pair (T1 , T2 ) is made unbalanced, the TR T1 is turned to a pseudo interruption state. The current I1 is passed through the TR T4 and thus, to flow through the TR T3 . Thus, an output terminal S behaves like the current source for supplying the current I1 . When the logic signals S1 are high (second mode), the current I2 is made to flow to the TR T20 , the different pair (T1 , T2 ) is balanced while generating the current (T1 +I2 )/2 and the output terminal S does not supply any current and is in the state of high impedance. Thus, the current source for supplying the current is switched by switching only an npn TR.
