  • Auxiliary artificial heart of an embedded type
    Patent number: 6336939
    Abstract: An artificial heart has a driving section, a nozzle section, a pump section for insertion into a ventricle of a human heart, and a sealing section forming a seal for a driving shaft extending from the driving section for driving the pump section. A sealing liquid chamber filled with a sealing liquid is formed around the driving shaft between the sealing mechanism and the driving section. The sealing liquid in the sealing liquid chamber maintains the sealing mechanism in a liquid-tight state and lubricates the sealing mechanism, whereby blood is prevented from entering the driving section. Even if blood happens to enter the driving section, the blood is mixed with the sealing liquid and does not coagulate. Thus, the operation of the artificial heart is not suppressed.

  • Magnetic disk controller for backing up cache memory
    Patent number: 5905994
    Abstract: A magnetic disk sub-system provides for sudden cutting off of a main power supply such as a power failure so that the backup by battery is effected to supply electric power to the cache memory from a battery upon cutting off of the main power supply in order to protect data in the cache memory and when the main power supply is cut off by operation of a main power supply switch the backup by battery is stopped to cut off supply of electric power to the cache memory from the battery after data in the cache memory is written into a magnetic disk unit and supply of electric power from the main power supply is then cut off. Further, the magnetic disk sub-system divides the cache memory into several portions so that the backup by battery can be controlled independently to thereby extend the backup period.

  • Purge solution circulating apparatus for artificial organ
    Patent number: 5810758
    Abstract: An apparatus for circulating a purge solution in an artificial organ has an ultrafiltration filter or reverse osmosis filter in a purge solution circulation route to inhibit passage of substances having molecular weights of 340,000 or more. A portion of the purge solution circulated by a purge solution circulation pump is passed through this filter to remove proteins that have mixed in the purge solution. The purge solution free from the proteins is supplied and circulated through the artificial organ. Proteins that have externally mixed in the purge solution can be prevented from coagulating and depositing on a seal mechanism and the like of the artificial organ.
