Filed: 1985-11-06
Abstract: PURPOSE:To prevent failure of communication or the like in a railway power transformer composed of a power rectifier and a power inverter by, when the voltage of the power inverter is less than a predetermined voltage for regeneration from the constant-current control, by shifting the firing phase so that it becomes higher than the output voltage of the power rectifier. CONSTITUTION:There is provided a phase lead priority circuit 14 which gives priority to any circuit of lead priority in a constant current control circuit 11, a constant excess angle control circuit 17 and a phase lag priority circuit 18, and a phase control circuit 19 is controlled by the output of the phase lead priority circuit 14, and there is further provided a phase shift circuit 21 to shift the phase by the output of a level detector 9, when the output voltage of the power inverter 4 becomes below the regeneration starting voltage, so that it may be higher than the output voltage of the power rectifier 3. Thus, the output current of the power inverter 4 is zero in the fixed phase condition at max. less than the regeneration starting voltage. And, when the zero output current is detected by a level detector 22, an AND circuit 23 generates an output to lock the output signal of a pulse amplifier 20.

Title: Pump driving method
Inventor: MIYATA SHINICHI
IPC: A61M1/10
Filed: 1987-09-30
Abstract: PURPOSE:To prevent the delayed diastolic action of a second pump and simultaneous ejection of a first and second pumps in a blood pump apparatus for an oxygenator by switching the chamber of the second pump to systolic action within a prescribed period after the start of dilation of the chamber of the first on the second pump. CONSTITUTION:The action of a slave pump is switched over to a systolic action as shown by a solid line at a time after the elapse of a predetermined set period t1 after the diastolic action of the slave pump chamber is started. As the result, the slave pump is made into a systolic mode during the diastolic period of a master pump, and the diastolic action of the slave pump is started in synchronism with the next systolic period of the master pump. The deviation speed in the diastolic period of the slave pump is measured, and the action is witched over at time point t1' or t2' even in the midway of diastolic action period when the speed is determined slower than a reference speed. After the start of the diastolic action of the master pump, at the selected time point t1' or t2' the slave pump is switched over to the systolic action. Because of the above-mentioned procedures, the delay in the diastolic action of the slave pump is prevented, thereby preventing the damaging on lungs caused by the simultaneous ejection action of the both pumps.

Title: Fluid pump
Inventor: NONAKA TAKESHI
IPC: F04B9/02
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To improve utility of a space in which a fluid pump is to be attached with its compact outer shape, by providing a pulsation smoothing pressure deformation member having flexibility and able to change the capacity in a valve housing member by pressure of fluid discharged from a valve. SOLUTION: Since a first plunger 31 repeats the reciprocating motion in a first cylinder block 30, pulsating flow is generated on fluid to be fed from a second valve body 34 into a discharge fluid housing part 45 of a first valve housing member 40. When pressure of the fluid is increased, a pulsation smoothing pressure deformation part 40c is made elastically flex in a direction to be separated from a first spring presser 39 to increase the capacity of the discharge fluid housing part 45, on the other hand, when pressure of the fluid is decreased, the pulsation smoothing pressure deformation part 40c is elastically restored in a direction to approach the first spring presser 39, and the operation is repeatedly performed in synchronism with the reciprocating motion of the first plunger 31.  Therefore, pulsation of fluid to be fed to first and second guide-out passages 6g, 6s through an orifice 40a1 is considerably decreased.
