  • Publication number: 20200282101
    Abstract: The purpose of the invention is to provide a tumor sealant to be used for therapy that enables curative treatment, by improving an extremely simple, minimally-invasive therapy consisting of starving tumor cells without radiation exposure or causing serious side effects by drugs. The invention provides a tumor sealant that utilizes the EPR effect specific to tumor cells, that covers the tumor cells of each tissue by particles that permeate only tumor blood vessels and accumulate and settle in the tumor, that does not release angiogenesis-inducing factors, that does not separate tumor cells having improved mobility in a hypoxic state and move them to another location, that permeates gaps of from 50 nm to 500 nm of the tumor vascular endothelial cells, and that biodegrades after adhering to the tumor cells and extracellular matrix near the gaps.

  • Patent number: 5646824
    Abstract: A flat shaped header having a heat receiving side is attached to a semiconductor element mounted on a circuit board. The header having the heat receiving side is connected to another header having a heat receiving side attached to a plurality of heat radiating fins so as to form a heat exchanging radiator which heat radiating fins are installed at a peripheral portion of a body of electronic equipment. The heat generated by the semiconductor element is transmitted by liquid moving between the headers via flexible tubes and then to the heat radiating fins, which heat is discharged outside of the body of equipment. Since the flat shaped header and the flexible tubes are employed, a high heat generating semiconductor element and the heat radiating fins are thermally connected with ease without being influenced by the configurational condition in the equipment even when many semiconductor elements are mounted inside a small space.

  • Patent number: 5360060
    Abstract: A fin-tube type heat exchanger has parallel heat transfer tubes and a stack of a plurality of plate fins mounted on the tubes. Heat exchange is conducted between a first fluid flowing through the tubes and a second fluid flowing through the stack across each of the fins. Each fin has flat tube-mounting portions spaced in the longitudinal direction of the fin and formed with tube-mounting holes and a louver section disposed between each adjacent pair of tube-mounting portions. The louver section has elongated slats extending longitudinally of the fin and having side edges each spaced from an adjacent side edge of an adjacent slat. The slats are classified into two groups in respect of the cross-sectional shape. The slats of one group have generally flat cross-sections to reduce the resistance of the fin to the flow of the second fluid through the stack and are disposed in planes offset from the plane of the tube-mounting portions.
