IPC: A61N1/362
Filed: 1991-02-15
Abstract: PURPOSE: To provide a pacemaker used for cardiac pulse conversion and clearing ventricular fibrillation having an ability to sense and respond to hemodynamic compromise. CONSTITUTION: A filtered peak, the peak amplitude or a peak pressure function is obtained by detecting ventricular pressure and electrical activity of heart 4 using a device and based on right heart and left heart ventricular pressure waveforms. The ventricular pressure and the electrical activity of the heart are sensed and processed continuously and the VFPPA or the VPPF are continuously derived. Using the VFPPA or the VPPF and electrocardiogram, regulation of bradycardia pacing or antitachycardia pacing as well as cardiac pulse conversion/defibrillation therapies are performed. The ventricular pressure and the electrical activity of the heart are continuously sensed and processed to determine whether or not some irregularity exists. When an irregularity exists, VPPF or VFPPA is derived and used to decide which of the therapies are necessary.  VPPF or VFPPA is derived periodically to ensure the most suitable hemodynamic function. The hemodynamic compromise is determined by comparing the derived VFPPA or VPPF with programmed value. The algorithm is so determined as the make the best effect of the pacing regulation.

Filed: 1982-03-17
Abstract: PURPOSE:To check progress of discharge reaction of an active substance up to an interface of the active substance of a grid and suppress generation of inert PbSO4 on the grid surface by making a quantity of the positive pole active substance, which is to be filled into a blank of the positive pole grid, and theoretical capacity of the positive pole in the specific range. CONSTITUTION:A quantity of the positive pole active substance to be filled into a blank of the positive pole grid is controlled to not more than 60% of the whole positive pole active substance and the theoretical capacity of the positive pole is made out less than 2.5 times of the theoretical capacity of an electrolyte. Thereby PbSO4 is made to be generated by priority in a position far from the vicinity of the grid, that is to say, on the pole plate surface part so as to make the active substance near the grid to remain in the condition of PbO2 and consequently the electrolyte becomes hard to diffuse near the grid when discharge is let alone, while, even when diffused, SO4 is consumed by PbO2 as the active substance remaining in the pole plate thus to suppress a change of a corrosive layer (PbO2 layer) of the grid surface into a nonwave-form PbSO4 layer.

Title: Dynamic load distribution method for parallel computer
Inventor: MIYAZAWA MINORU
IPC: G06F9/48
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To reduce the quantity of load to be required for dynamic load distribution and to improve the efficiency of processing by executing dynamic load distribution so as to request task allocation to another processor after judging that a certain processor can not process a request task newly generated in the processor itself. SOLUTION: When a task generation request is generated in a certain processor, the processor executes practicability/impracticability judgement for the task based upon load information and task information (1). At the time of judging impracticability, the processor acts as a sender, the sender selects a processor having a processor number next to that of the sender itself as a receiver candidate (3) and transmits the task information to the receiver candidate. When the candidate has a margin, i.e., quali-fiction (6), for processing the task at the time of receiving a qualification judgement result from the candidate, the candidate is determined as a receiver (7) and task allocation is requested to the receiver (8).
