Title: Reciprocal pump suitable for use in artificial heart
Inventor: SUTEITSUGU RUNDOBETSUKU
IPC: A61M60/882
Filed: 1985-03-28
Abstract: A double pump adapted for use as an artificial heart includes two ventricle-simulating chambers that are provided with respective inlets and outlets having valves incorporated therein and that are separated by a common partitioning wall structure. The wall structure has sections that are driven away from each other to reduce the volumes of respective ventricle chambers and expel liquid from the chambers through the outlets. The wall structure can also move laterally in response to differences in pressure between the chambers and hence change the volumetric ratio between them. This ensures a balanced action between the two halves of the heart- simulating pump during a systole phase and a diastole phase. The link mechanism is actuated by a cord through a motor, although only in one direction in the pressure phase, and hence the aforementioned changed volumes are readjusted primarily through the pressure exerted by the inflowing fluid. The pump may also include a variable volume atrium-simulating chamber communicating with the inlet to each ventricle-simulating chamber and having volume that is controlled in part by an externally acting gas pressure that varies in accordance with changes in the volumes of the ventricle chambers.

Title: Protective circuit of inverter power ic and hybrid integrated circuit integrating this protective circuit
Inventor: MAEHARA EIJU
IPC: H01L21/822
Filed: 1988-03-16
Abstract: PURPOSE:To detect a stable large electric current by a method wherein an inverter power IC and a protective means having a detection resistance formed by a low- resistance metal are formed on the same substrate. CONSTITUTION:When a signal at an 'H' level is output from a comparator 6, a transistor Tr116 turns on, a photocoupler Dc117 turns on and a transistor Tr218 turns off. When the transistor Tr218 turns off, a large electric current is shut off and a power semiconductor element 8 is protected. One part of a conductive route 9 is utilized as a detection resistance R0; a section between a point (a) and a point (b) near the power semiconductor element 6 is used as the detection resistance R0. A bridge circuit for current detection use is formed near the detection resistance R0; a key-shaped protruding part 10 is formed at an end part of the detection resistance R0. A total resistance of the detection resistance R0 is the sum of an internal resistance from an arbitrary point lx of the protruding part 10 l1 to the point (a) and an internal resistance from the arbitrary point lx to the point (b). Accordingly, when the arbitrary point lx is changed, a resistance of the detection resistance R0 can be adjusted. By this setup, even when the detection resistance is heated by the large electric current, it is possible to detect a stable large electric current irrespective of a change in a temperature thanks to a protective means.

Title: Electrolytic cell for hydrogen peroxide preparation and electrolytic preparation of hydrogen peroxide
Inventor: NAKAMATSU HIDEJI
IPC: C25B9/19
Filed: 1993-02-26
Abstract: PURPOSE: To make a gas electrode which is heretofore unusable for electrolytic production of hydrogen peroxide as this gas cathode does not have the resistance to a corrosive catholyte usable in the electrolytic production of the hydrogen peroxide.  
     CONSTITUTION: The cathode chamber 4 of an electrolytic cell 1 for hydrogen peroxide production segmented from an anode chamber 3 by a cation exchange membrane 2 is segmented to a soln. chamber 7 where the corrosive catholyte exists and a gas chamber 10 where the gas cathode 8 is housed by an anion exchange membrane 6 in tight contact with the gas cathode 8. The gas cathode 8 is prevented from coming into direct contact with the catholyte by the presence of the anion exchange membrane 6. Further, the longer life of the gas cathode may be achieved by the intrinsic absence of the corrosive material in the gas chamber and in addition by the prohibition of the leakage of the catholyte into the gas chamber 10 by the anion exchange membrane 6 and the elimination of indirect contact thereof. Further, the leakage described above may be prevented even if the electrolytic cell is formed to a larger size and, therefore, this process is applicable also to the electrolysis in an industrial scale which cannot be heretofore achieved with the conventional gas electrode.

Filed: 1983-04-11
Abstract: PURPOSE:To obtain a multi-value Walsh spectrum close to a Fourier spectrum by using only an adder/subtractor or a shifter and the adder/subtractor. CONSTITUTION:A time series data of a complex number is inputted to a buffer memory section 1 and stored temporarily. Since the operation of a 8-value Walsh conversion is an operation of multiplication of (+ or -i, + or -j), only the addition/subtraction is executionable. The calculation is advanced from the 1st stage to the n-th stage by a control signal of a control section 3. The data is read from a buffer memory section 1 for processing each state, a butterfly operation, i.e., yi=xi+xj.ak; yj=xi-xj.ak is executed and the result is written again in the buffer memory section 1. The butterfly operation is obtained by a multi-value (8- value) Walsh operating section 2. In the butterfly operation, the xi.xj is read at first, and each real part and imaginary part are stored in registers 201-204. Multiplication of complex number xj.ak is obtained by the equation. The addition and subtraction are executed for the real part and the imaginary part respectively at adders 231, 232 and subtractors 233, 234.
