Title: Method of starting polyurethane-polycapramide conjugate fiber spinning
Inventor: TSUCHIMOTO AKIHARU
IPC: D01F8/12
Filed: 1979-03-12
Abstract: PURPOSE: When conjugate spinning of polyurethane and polycapramide is started, the polyurethane is passed through the paths at a low temperature to surpress the decomposition, thus producing conjugate fiber with high stretching property by stable operations.  
     CONSTITUTION: (A) a thermoplastic polyurethane is flowed from melting zone 1 through path 3 without setting spinneret 5 at a temperature 3W15°C lower than the normal spinning temperature. Then, the temperature is raised to the normal one and (B) polycapramide is passed from melting zone 2 through path 4. Finally, spinneret is mounted and the conjugate spinning is started.

Title: Method for regenerative control of electric rolling stock
Inventor: TOYA IKUYA
IPC: B60L7/00
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To provide a method for regenerative control of a electric rolling stock by which the service life of the contact of a circuit contactor can be prolonged by controlling detaching timing of the contactor as the basis. SOLUTION: A method for regenerative control is used for controlling the regeneration of an electric rolling stock which is provided with a running circuit capable of making both power running and regeneration. In the method, regeneration/power running discriminating conduction is performed for conducting a main switching section plural number of times with a small pulse having a narrow turn-on width in a state, where a regeneration contactor is closed, and either a forward contactor or a reverse contactor is closed in accordance with the instruction from a direction indicator. After the regeneration/power running discriminating conduction is made, the armature current Ia of the plugging current Ip of a DC motor is detected and propriety-of-regeneration discrimination is performed for discriminating the propriety of regeneration, based on the detected value of the current Ia or Ip and a preset regenerable reference current value Id. When it is determined that the rolling stock is regeneratable as a result of the propriety-of-generation discrimination, regeneration contactor delaying and detaching processing is performed for opening the regeneration contactor, when an extremely short time t1 elapses and the armature current becomes a sufficiently small value after the regeneration/power running discriminating conduction.
