Filed: 1984-10-23
Abstract: PURPOSE:To obtain the titled yarn having reduced hang-up and turbulence of single yarn, by extruding a spinning stock solution consisting of a high- molecular-weight-polyethylene from a nozzle to form yarn, and drying it in such a way that a solvent content is made into a specific ratio. CONSTITUTION:A polyethylene having >=800,000wt.-average molecular weight is dissolved in a solvent such as nonane, decane, etc. in such a way that the concentration of the polyethylene is 3-20wt%, to give a spinning stock solution. Then, the spinning stock solution is extruded from the spinning nozzle, cooled and solidified at <=20 times, preferably 1-15 times spinning draft and made into yarn. Further, before the prepared undrawn spun yarn is wound round a bobbin or continuously drawn, it is dried with 50-110 deg.C hot air at constant length or under <=20% contraction or under elongation in such a way that the content of the solvent is <=20wt% based on the polyethylene, to give the aimed undrawn yarn.

Title: Power circuit for lamp of electric apparatus
Inventor: TADA SHIGEO
IPC: H05B37/02
Filed: 1989-08-30
Abstract: PURPOSE:To reduce a notching phenomenon on the filament of incandescent lamps even in a DC lighting system and lighten the life of the lamps by providing a current direction switching part which reverses the current direction of the incandescent lamps based on a signal generated in an operation part at the operating time. CONSTITUTION:When key input operation is made at an operation part 2, a mute output signal M is outputted from a control part 3 to a regeneration circuit 4 and a JK flip-flop circuit 8 so as to reverse output of a terminals Q and Q of the JK flip-flop circuit 8. Consequently the direction of current flowed to lamps is reversed, whenever an operation part 2 is operated, that is the same as AC lighting in practice. It becomes few to cause electro-migration and controls notching phenomenon lengthening the life of the filament of lamps in this way.

Title: Superconducting fuse
Inventor: EBIHARA MASAAKI
IPC: H01H85/06
Filed: 1988-09-09
Abstract: PURPOSE:To rapidly and surely reduce or cut off a current therethrough when an excess current, an excess magnetic filed, an excess temperature rise or their combined type anomaly is generated by constructing the main body of a fuse from superconducting material and setting the critical value of the superconducting material in such a way that it is held in its superconducting state when its aimed load is normally operated, whereas in its normal conducting state when the anomaly is generated. CONSTITUTION:While in its normally operated condition where the value of a current passing through a superconducting fuse 6 is below its preset ceiling value, the superconducting wire 6b of the superconducting fuse 6 is in its superconducting state so that a current is supplied to a load 4. But, when a current the value of which exceeds the ceiling value is caused to flow through the load, then the superconducting wire 6b instantly shifts to its normal conducting state to generate electrical resistance. A Joule heat is therefore generated by both the electrical resistance and the current, so that the superconducting wire 6b is fused in quite a short time to cut off the circuit 2.
