Inventor: YAMADA MITSUO
IPC: E02D27/01
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To provide a foundation of a building requiring simple foundation work and excellent in earthquake resistance at a low cost. SOLUTION: Such a structure is employed that the upper face 1a of a foundation 1 is made flush and a groundsill 6 is fastened to the upper face of the foundation 1 without providing a buildup section (continuous footing section) arranged on a continuous footing or a solid foundation employed in the past. The ground may be dug only at the outer periphery section of the foundation for the foundation work, and rubbles 4 are merely installed on the inside. There is no continuous footing section on the inside, and the work quantity for digging a ditch and installing a form can be made very small. Ventilating holes essential to the continuous footing section reduce earthquake resistance due to stress concentration, however the ventilating holes are provided between groundsill packings 8 or the groundsill 6 and a floor in this case, and the problem of earthquake resistance is resolved.

Title: Method and device for providing criteria for extra-systole frequency and gravity
Inventor: BONNET JEAN LUC
IPC: A61N1/362
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To perform a process to judge the criterion for the generation frequency or the gravity of an extrasystole phenomenon, and control this kind of device by providing a means to increase an extrasystole counter in response to detected extrasystoles, and a means to decrease the extrasystole counter in response to an absence of the extrasystole. SOLUTION: At the initial stage of a system, an extrasystole counter ES is set at 0. Phenomena which occur in the atrial and ventricular chambers of a heart are monitored and detected by an active implantable medical device (stage (S) 10), and in addition, the existence of an extrasystole is detected (S20). When an independent extrasystole is judged (S30, no), the extrasystole counter increases by adding a proper dosage, and in the opposite case, becomes a dosage 1 (S40, no; S45). When the occurrence of the extrasystole is frequent (S40, yes), the extrasystole counter increases, e.g. by an arithmetical progression at 1, and is multiplied by the number of detected extrasystoles (S50). When there is no existence (S20, no), the extrasystole counter decreases by a dosage correlating the ES counter for each cycle, especially by 1 (S25).
