Abstract: PURPOSE:To enable it to absorb all the vibrations over the extensive frequency by installing a limiting means, limiting a flow of liquid, in at least either of an elastic body equipped with plural small liquid chambers and a limiting passage interconnecting these small liquid chambers. CONSTITUTION:When a vehicle runs at high speed, there is produced a shake vibration. If a control means 60 is so judged that it is at time of shake vibration occurrence by a car speed sensor 62 and an engine speed sensor 64, it operates a stepping motor 48, making a shaft 50 move toward an inner cylinder 12. Consequently, a blocking valve 52 canes into contact with a bottom surface of an orifice member 20, blocking a hollow part 21. In addition, qhwn an engine is idling as well as when car speed is less than 5km/h, there is produced an idling vibration. If the control means 60 judges that it is at time of generating this idling vibration, this control means 60 will not operate the stepping motor 48. Accordingly, the shaft 50 is in a state of being left stopped intact, so that the blocking valve 52 is in no case blocked the hollow part 21.

Filed: 1990-05-21
Abstract: PURPOSE:To enable the obtaining of an image low in artifact with high resolutions by compensating for a DC offset voltage on the output side of an orthogonal detection circuit to eliminate effect of the DC offset. CONSTITUTION:When a DC voltage contained in an ultrasonic signal of an output of an orthogonal detection circuit 14 is detected, it is a so-called DC offset voltage. Therefore, by adding polarity of the voltage inverted to an output of the orthogonal detection circuit 14, the DC offset voltage is corrected. By performing this series of operation for individual channels of an array probe 1, the DC offset voltage of the channels is compensated for. This can eliminate effect of the DC offset thereby obtaining an image low in artifact and with high resolutions.
