  • Patent number: 5526601
    Abstract: A generally tubular flexure sensor is constituted by winding a piezoelectric element including a polymeric piezoelectric strip provided with oppositely disposed surface electrode layers on both surfaces around a central axis (helical axis) so that the surface electrode layers are disposed substantially in parallel with an extension direction of the helical axis, and combining the helically wound piezoelectric element with a detection circuit for detecting a flexural deformation of the piezoelectric element in a direction perpendicular to the helical axis. The flexure sensor allows a large degree of flexural deformation in any direction to provides a good sensitivity and can be suitably used as a fish catch signal sensor for a fishing rod.

  • Patent number: 5168880
    Abstract: A method of heating a tract organ of the living body with high-frequency electric current, includes the step of controlling a flow volume of a coolant supplied into a first electrode so as to be substantially equal to that of a blood which flows in a living body tissue at a portion where the first electrode is disposed while controlling a temperature of the coolant to a temperature range of the living body tissue at the portion, the coolant being an aqueous solution of salts at a predetermined concentration.The method makes it possible to effect safely a hyperthermic treatment.An apparatus for carrying out the method is also disclosed.

  • Patent number: 5086786
    Abstract: An electrode device for heating a tumor in an endotract organ by high frequency convergent electric current has a container of a flexible polymeric material provided with thick side wall, a thick bottom wall connected to one end of the side wall and an opening defined by the other end of the side wall. The device further has a deformable electrode member disposed near an inner surface of the thick bottom wall, and a flexible polymeric film fluid-tightly attached to the other end of the thick side wall. A mesh-like member of a flexible polymeric material is disposed between the electrode member and the flexible polymeric film, and has a plurality of first passages leading to a top surface thereof and a bottom surface thereof, and a plurality of second passages each communicating the first passages with each other.

  • Patent number: 5006111
    Abstract: A medical pump device is constructed so that a pulsation force is applied to the blood in the vicinity of an artery, which is reconstructed after a bypassing operation has been completed, so as to compensate for a deviation of an actual wave form of a blood flow in the vicinity of the reconstructed artery from a normal wave form thereof. The medical pump device is capable of minimizing the possibility of occurrence of a late obturation in an artery which is reconstructed after a reconstruction operation has been completed, and improving a rate of keeping open the reconstructed artery.

  • Patent number: 4961435
    Abstract: A high-frequency capacitive heating electrode device comprises a cap-shaped electrode, a flexible support for supporting the electrode with one end thereof capped with the electrode, a flexible polymer film which surrounds the electrode and forms a gastight space between the support and the flexible polymer film, and passages for respectively introducing and discharging a cooling medium to and from the gastight space. The high-frequency capacitive heating electrode device is disposed in the vicinity of the target portion of a living body to be heated and is useful for the hyperthermia therapy for a cancer of the uterine cervix.

  • Patent number: 4039290
    Abstract: A fluidized bed type spent activated carbon regenerator with an upper drying chamber and a lower reactivating chamber within a column through which spent activated carbon particles are treated in a fluidized state. The regenerator has a distributor at the lower end of a spent carbon feed pipe which opens into the upper chamber to distribute the feed of spent activated carbon uniformly on all sides of the feed pipe and over a larger area in the upper chamber. A hood is mounted around an upper end of a first overflow pipe which provides a passage to the lower chamber for carbon particles devolatilized in the upper chamber to block shortpasses of incompletely devolatilized carbon particles to the lower chamber. The regenerator is further provided with a louver strainer at the ceiling of the upper chamber to block fine carbon powder which tends to leave the regenerator entrained in upward streams of a regeneration gas flowing through the upper chamber toward a gas outlet at the top of the regenerator.
