Abstract: PURPOSE: To reduce burden of managing body fluid balance of a patient to an operator, by providing a volume measuring means for measuring intermittently filtrate flow volume on an exhausting side of a filtrate pump, and controlling rotating speed of the filtrate pump so that the obtained measured value of filtrate is matched with a set value. CONSTITUTION: Filtrate is flowed into a measuring container 7 when an opening/ closing valve 9 is opened and a filtrate clamp 8 is closed during rotating a filtrate pump 3. The filtrate clamp 8 is opened while the opening/closing valve 9 is opened thereby the filtrate in the measuring container 7 is flowed out when surface of liquid is beyond a lower filtrate level sensor 10a and reaches an upper level sensor 10b. These operations are repeated at a specified interval, and a time necessary for flowing into the measuring container 7 is measured as the time until the liquid surface is beyond the lower filtrate level sensor 10a and reaches the upper filtrate level sensor 10b, the flow volume of the filtrate pump 3 is calculated from this time and the volume of the measuring container 7. The rotating speed of the filtrate pump 3 is controlled so that this filtrate flow volume is matched with the set value.

Abstract: PURPOSE:To conduct the divided injection of RI solution with a precise radioactive amount by sucking the air corresponding to the tube internal capacity of a drain route and draining the tube internal solution with the air as a buffer to drain a solution remaining in the tube by a syringe. CONSTITUTION:A piston 8 is pulled out from the point (a) to the air sucking termination point (b) by a driving device 7 to suck the air corresponding to the tube 5 inner capacity into a syringe 2. The piston 8 is pulled out up to the solution sucking termination point (c) to sample a determined amount of RI original solution into the syringe 2 from a RI vial 1. The piston 8 is pushed in up to the point (a) of the syringe 2 with the air as a buffer material, and the determined amount of the RI original solution is injected into a diluting vial 4. According to the above constitution, the top end part 12 of the piston 8 is never made in contact with the RI original solution, and thus, by conducting sampling and injection by the same procedure on and after the following divided injection operation, the radioactive amounts of the RI solution injected in the diluting vial and the raveling vial are made precise.

Abstract: PURPOSE:To enable a reduction in the possibility of radiation exposure by introducing a determined amount of radioisotope(RI) solution direct into a diluting vial from a IR generator integrally combined into a device by on-line and measuring its radioactivity. CONSTITUTION:A determined amount of RI solution is sampled into a syringe 32 from a RI generator 30 by the opening and closing of opening and closing valves 36, 37 and the operation of the piston 35 of the syringe 32, then the determined amount of the RI solution is injected into a diluting vial 31. The radioactive strength of this RI solution is measured by a radiation detector. On the other hand, a determined amount of physiological salt solution from a physiological salt solution vessel is sampled into a syringe 40, and then the opening and closing valve 39 is opened to inject the determined amount of the physiological salt solution to the diluting vial 31. Hence, the specific radioactivity can be determined from the amount introduced into the vial 31 and the radioactive strength measured by the radiation detector. As a determined amount of the RI solution can be automatically obtained direct from the RI generator in this way, the possibility of radiation exposure of operators can be reduced.

Abstract: PURPOSE:To fractionate conveniently superconductive ceramic powder in a powder mixture from other impurities by holding a ceramic powder mixture at a specified critical temp. and applying a magnetic field to the powder mixture. CONSTITUTION:Superconductive ceramic powder is fed from a foot end of a pipe 1 while holding the powder at critical temp. (Tco), and then passed through a magnetic field (a) formed by a solenoid coil 3. In this stage, starting materials contained in the ceramic powder mixture, insulative impurities, and/or strongly diamagnetic superconductive ceramic having a critical temp. =Tco can not pass through the range of breadth of the magnetic field (a), and separated and left as liquid suspension in the pipe 1 below a position where the coil 3 is attached.

Abstract: PURPOSE:To automate the measurement of a specific surface area, by arranging sample cells filled with the sample at prescribed intervals and connecting a rotary valve to these sample cells and then, allowing to move a Dewar vessel. CONSTITUTION:For example, six samle cells b are arranged at regular intervals and rotary valves R, R' for supplying and discharging a carrier gas are connected to these cells b. It is constructed that a Dewar vessel cooling each cell b is made to be capable of moving up and down and also, is moved at the same pitch as the arranging intervals of the cell b. Accordingly, the measurement of the specific surface area of the sample is automated perfectly and is measured accurately.

Abstract: PURPOSE:To detect the change-over position from a low speed injection speed to a high speed injection speed always accurately by detecting the position of a plunger at the point of the time when the pressure during injection of a die casting machine rises abruptly as said change-over position. CONSTITUTION:Pressure sensors 11, 12 emitting signals by measuring changing pressures are provided on the head end side and rod end side of an injection cylinder 8, and the signals thereof are fed to an operator 14 through an amplifier 13. Since the pressure on the head end side and rod end side while the cylinder 8 is advancing at a low speed are relatively low and constant, the abrupt changes in the pressures are detected with the sensors 11, 12, and the injection stroke positions of that time are displayed on a display surface 21. Hence, it is possible to know the change-over position to a high speed injection speed always accurately.

Abstract: PURPOSE:To additionally improve the accuracy of decision of the presence or absence of a cerebral blood vessel trouble by forming the adhering part of a coupler and a diaphragm to a shape which is approximately analogous with the shape of the diaphragm, thereby reducing peak frequencies to a single frequency and decreasing the disturbance in the frequency characteristics thereof. CONSTITUTION:Unbalance arises in effective vibration length and, therefore, plural peaks appear in the frequency characteristics if the adhering surface of the coupler 3 for connecting the diaphragm 2 and a high-polymer piezoelectric film 5 and the diaphragm 2 is larger than the diameter of the diaphragm 2. The many resonance frequencies appear near the resonance frequency by a difference in the effective vibration distance of the diaphragm 2 and the characteristics having many peaks and dips are exhibited in the case of such adhesion state of the coupler 3 and the diaphragm 2 in which the lengths of b and c vary considerably. Then, the adhering part of the coupler 3 to the diaphragm 2 is formed to such a shape which is approximately analogous with the shape of the diaphragm 2 so as to nearly equal the lengths of b and c, by which the single peak frequency is obtd. and the converter having the good frequency characteristics free from the disturbance in the frequency characteristics is obtd.

Abstract: PURPOSE:To facilitate the finding of condition of an device generating an external sound, by converting the external sound into an electrical signal detecting it with a pickup to check an interval of generating the electric signal. CONSTITUTION:A pickup signal PS is amplified 2 to be supplied to a rectifier circuit 4 through a band pass filter 3. The rectification circuit 4 converts an input signal into a DC signal DS and the signal only above a reference voltage VR is supplied with a comparator 5 to a waveform shaping circuit 6. The circuit 6 shapes the waveform of an input signal to be supplied to a retrigger multivibrator 7 as trigger signal TS while controlling the flashing of a light emitter 8. As each trigger signal TS is inputted, the vibrator 7 generates an output signal SS of an L level for a set 7a time length T1. The signal SS maintains the L level while a time interval T2 of the signal TS inputted is shorter than the set time length T1 and rises to an H level with the passage of the set time length when the time interval is longer than the length. This enables detection of changes in the time interval of the input signal with the vibrator 7.
