Title: Exhaust system supporting device for transversely placed v-engine
Inventor: SUZUKI MASAYUKI
IPC: F02B75/22
Filed: 1989-09-13
Abstract: PURPOSE:To surely suppress a resonance phenomenon of vibration of an exhaust pipe with that of an engine by rigidity-coupling the joined exhaust pipes to the side of the engine in a location where extension lengths of exhaust pipe are equal to each other from front and rear cylinder blocks. CONSTITUTION:In a V-engine 6, in a location where extension length of a front exhaust pipe 2 from a front part cylinder block 1 and that of a rear exhaust pipe 4 from a rear part cylinder block 3 are obtained equal, both the exhaust pipes 2, 4 are grasp-tightened by a clamp 9 which is mounted by a bolt 11 to a bracket 10 provided in a transaxle 7, and the exhaust pipes 2, 4 are rigidity-connected to an engine side in the above described location. During operation of the engine 6, the joined exhaust pipes 2, 4 tend to swivel in a longitudinal direction (right and left directions in the drawing) with a cylinder side mounting part serving as the center. However, this swivel action is suppressed by the bracket 10 through the clamp 9, and the swivel action is prevented from vibration-exciting a car body through an exhaust mount and from transmitting an internal noise to the inside of a car room, by a resonance phenomenon with the engine 6.

Filed: 1991-09-17
Abstract: PURPOSE:To provide a video signal with fidelity to picture information by obtaining a light signal and a dark signal from same optical sensor and using a difference between the signals as the video signal. CONSTITUTION:A switch S3a is closed and an optical sensor s1a is charged for a period t1. Sensors (s) of an odd number order are connected to a light output line and sensors (s) of an even number order are connected to a dark output line. A charge current of the s1a is produced on the light output line 8. Switches S3a, 3b are closed and the sensors s1a, s1b are charged for a period t2. The sensors (s) of an even number order are connected to the light output line and sensors (s) of an odd number order are connected to the dark output line. Since the charging time of the s1a is finished for the period t1, only the dark output flows to the dark output line 9 from the s1a, the charge current of the s1b flows to the light output line 8. Then the light signal is outputted to the line 8 and the dark signal is outputted to the line 9. Thus, a video signal with fidelity to picture information is obtained without dispersion in the dark signal and the double speed operation is attained.
