Title: Correlation type ultrasonic flow velocity measurement device
Inventor: ISHIZUKA YOSHIZOU
IPC: G01P5/22
Filed: 1990-09-29
Abstract: PURPOSE:To minimize an attenuation effect due to a biotissue, and accurately obtain a flow velocity on a real time basis by calculating the flow velocity on the basis of a time difference in a ultrasonic echo intensity reflected from two or more zones. CONSTITUTION:The initial value of a time difference Td in wave transmission between oscillators 40 and 41, is rest at a maximum level HD in a sample hold circuit 68. A trigger generation circuit 46 outputs a transmission trigger pulse for the time difference Td. The oscillators 40 and 41 transmit signals on the basis of a time difference and receives an echo for detection with detection circuits 56 and 58. On the other hand, counters 30 and 34 respectively output sampling pulses SP1 and SP2, when the values of t1=N1CLK and t2=N2CLK become zero. A computing element 64 outputs a subtraction SD for the intensity of echo signals at t1 and t2, and a comparator circuit 70 compares a signal AD with another signal HD. A latch circuit 30 stores a wave transmission time difference Tmax for the time when the correlation of echo intensity becomes maximum between the oscillators 40 and 41. CPU 24 calculates a flow velocity V12=L12/DELTA tmax and sends the value of the velocity to a display 72. According to the aforesaid construction, the velocity of a fluid in a subject to be examined can accurately be measured, even if a complicate organ exists as in the case of a living body.

Title: Wet start clutch
Inventor: SHIMAMOTO MASAO
IPC: F16H61/30
Filed: 1985-11-19
Abstract: PURPOSE:To enable a smooth start to be realized, by regulating clutch oil pressure by centrifugal force of a mass body so as to have the clutch engaging force generated in proportion to the square of rotational speed. CONSTITUTION:Whenever the rotational speed of an input shaft is gradually increased, in the condition that the master pressure is led to an oil pressure chamber 6 a valve inlet 16a is closed by centrifugal force in proportion to the square of the rotational speed.
