  • Publication number: 20190235586
    Abstract: The electronic device includes a case, an antenna element, a heat source, a heat dissipation member, a heat conduction member, a cooling fan, an exhaust port, and an exhaust duct. The case has a pair of main surfaces and side surfaces. The antenna element is used to perform wireless communication. The heat dissipation member exchanges heat with a cooling wind. The heat conduction member conducts heat of the heat source to the heat dissipation member. The cooling fan generates the cooling wind to be blown to the heat dissipation member. The exhaust port is an exhaust port from which the cooling wind is discharged to the outside. The exhaust duct guides the cooling wind to the exhaust port. The exhaust port is disposed on one of the side surfaces, and the antenna element and the exhaust duct are disposed to overlap each other at least partially in the thickness direction.

  • Patent number: 10345442
    Abstract: A collision possibility determination device includes: a detection unit which detects at least one object which moves relatively with respect to a moving body; and a determination unit which determines a collision possibility of the moving body with the object. The determination unit defines a first factor and a second factor which are spaces between the body and the object in a travelling direction and in a width direction of the body respectively. The determination unit determines the possibility based on the two factors when the object is within a farther area from the body, and the possibility based on only the first factor when the object is within a nearer area from the body.

  • Patent number: 5756031
    Abstract: A process for the preparation of polybenzazole filaments which comprises (a) extruding a solution of polybenzazole polymer in a mineral acid through a spinneret having at least 100 holes, which are arranged to form a annular pattern around the center of the spinneret, the center and at least two radial sections of the spinneret having no holes and an average width which is at least about 3 times the minimum pitch of the holes, thereby forming filaments of the polymer solution; (b) drawing the filaments of the polymer solution through a quench chamber while providing a substantially radial gas flow therein across the spinneret from at least two different directions; and (c) washing and drying the filaments of the polymer solution under conditions sufficient to form polybenzazole filaments.

  • Patent number: 5585052
    Abstract: The invention is a process for the preparation of polybenzazole staple fibers which includes extruding a solution of polybenzazole polymer to form a dope filament, cutting the dope filament to a desired length, and washing and drying the cut filament. It has been discovered that the process of the invention provides a suitable means to prepare staple fibers which does not require the cutting of washed, rigid polybenzazole filaments.

  • Patent number: 5393478
    Abstract: Fibers spun from polybenzazole dopes can quickly be washed to remove polyphosphoric acid by a combination of initially washing with an acidic liquid and second washing with a hot leaching fluid at at least about 60. The process can reach acceptable residual phosphorous levels (1500-2000 ppm) in as little as about 2 or 3 minutes.

  • Patent number: 4963310
    Abstract: A process for the production of polyester polyurethane elastomeric fibers having improved humid aging resistance which comprises the steps of reacting a polyester diol with an excess molar amount of an organic diisocyanate to prepare a urethane prepolymer having terminal isocyanate group at both ends thereof; extending the chain of the prepolymer with a bifunctional active hydrogen compound and 0.5 to 10.0 mole % of a diaminosilyl compound based on the total amount of the bifunctional active hydrogen compound during or after preparation of the prepolymer to obtain a polyurethane; spinning the polyurethane into fiber; and crosslinking the polyurethane during or after spinning.

  • Patent number: 4105740
    Abstract: Stretching polyester tows at a speed greater than 150 m/min., wherein more than 85 mol percent of the recurring units are units of ethylene terephthalate, is carried out at a stretch ratio satisfying the formula-1.58log(.DELTA.n .times. 10.sup.3) + 4.18 .ltoreq. DR .ltoreq. -2.32log(.DELTA.n .times. 10.sup.3) + 5.93Wherein .DELTA. n represents the birefringence of the unstretched filaments and is a value of from 0.020 to 0.100, and DR is the stretch ratio in times.
