Abstract: PURPOSE: To accomplish handy and accurate measurement of the fluidity of suspension by connecting a pressure air tank and a pressure gauge to the U-shaped tube.  
     CONSTITUTION: A U-shaped tube 3 filled with a suspension is arranged in the thermostatic oven with a pressure gauge 4 connected to one end thereof while a pressure air tank 1 having a pressure gauge 2 connected thereto is connected to the other end through a pressure gas conduit 5. Pressure gas is fed into one end of the U-shaped tube 3 from the pressure gas conduit 5 through the pressure gas tank 1 to pressurize the suspension, and thus, the pressure given by the pressure gauges 2 and 4 are read increasing the pressure gradually. The pressure on the pressure gauge 2 is determined as the fluidizing pressure when the pressure given by the pressure gauge 4 increases suddenly to approximate the pressure of the gauge 2. Then, the suspension is allowed to stand for a predetermined period once the pressure is released. Thereafter, the fluidizing pressure is obtained by repeating the  same procedure. Accordingly, it is possible to measure the fluidity of the suspension  in handy manner and accurately with a limited sample.

Title: Write pen detecting system
Inventor: SAKURAI KUNIHIKO
IPC: G06F3/037
Filed: 1980-05-01
Abstract: PURPOSE:To make the touch position of a write pen detectable despite the use of a display device using a CRT of long afterglow characteristics by changing the display state only when the write pen is touched in a write pen detecting system. CONSTITUTION:When an operator touches a write pen 4 in the character and symbol position of the display image plane of a CRT display device 7, a switch 2 operates and a control circuit 5 causes a display signal generating part 6 to output the signal periodically inhibiting displaying of the whole or part of the image plane. Thereby, the signal by the sufficient change in the quantity of light is sent from the photodetecting part of the write pen to the control part 5, whereby the touch position is detected. Upon completion of the detection, the output of the inhibit signal is stopped to return the image plane to the original one. Since this obviates the infeasibility of the detection of the touch position owing to afterglow, the CRT of long afterglow characteristics is used as a CRT for display device and no uncomfortable feel is given to the operator.
