Title: Large-capacity valve
Inventor: MATSUOKA TAKANORI
IPC: F16K7/17
Filed: 1981-12-15
Abstract: PURPOSE:To obtain a large-capacity valve having a large sectional area of fluid  passage and a relatively short response time, which is used as a valve for a  high-speed shutter or the like used in a neutron injecting apparatus for nuclear  fusion. CONSTITUTION:The upper side of a valve chamber 19 formed in a valve body 11 is covered with an annular, resilient diaphragm 22, and a valve cap 23 is fixed to the top of the valve body 11. When pilot valves 31 are de-energized and pilot pressure is not acted to a pilot pressure chamber 24, the diaphragm 22 is moved away from a valve seat 15, so that fluid is carried from a supply port 12 to an annular air supply passage 20, and passing through the valve chamber 19 above the valve seat 15, an annular exhaust passage 22 and an annular exhaust port 13, is then discharged to the outside from an outlet 14 while raising the diaphragm 22 upward. On the other hand, when pilot pressure is applied to the pilot pressure chamber 24 by energizing the pilot valve 31, the diaphragm 22 comes into tight contact with the valve seat 15, so that the fluid passage is closed.

Abstract: PURPOSE:To clearly display even the smooth and well connected image of the rapidly moving part of an internal organ by providing a scanning correlation circuit changing in the ratio of scanning correlation according to the difference of a signal level. CONSTITUTION:The scanning correlation circuit 4 provided to the front stage of an image memory 5 receives the output of the image memory and novel input to perform correlation with respect to the data before one time phase and the present data at the same place on a tomographic image. The value range of the data of the scanning correlation circuit 4 is set to 10-15 decimally and, when there is difference of 4 or more between the data before one time phase and the present time phase data and it is supposed that the movement of an internal organ is rapid, old data is fed back to new data in a definite ratio to be outputted. Since there is difference of 4 or more in the part of a region (a), the new data is outputted as it is supposing that the movement of the internal organ is rapid. By this method, an image easy to observe is obtained even with respect to a rapidly moving internal organ.

Title: Dc motor runaway detection method
Inventor: OTA YOSHIAKI
IPC: H02P7/06
Filed: 1989-08-02
Abstract: PURPOSE:To see that a motor is not damaged when a transistor has broken down in short conditions by detecting the speed of a motor based on the photosignal from a rotary encoder so as to detect it as runaway condition when the speed difference between instruction speed and detection speed has become over some value. CONSTITUTION:Upon runaway of a motor, the period of the photosignal from a rotary encorder is shortened. Thereupon, the value that a counter 4 counts within a certain time becomes large. This value is corresponding to the motor speed, and if this value and the value of instruction speed data are input into a speed arithmetic circuit 5, speed difference data can be obtained. The larger the value of the counter 4 (than the instruction speed data), the larger the speed difference data. At this time, if the speed difference exceeds over a set value, and arithmetic circuit 7 detects the runaway of the motor, and outputs an alarm signal.
