Title: Production of fancy yarn
Inventor: MIYAZAKI TAKAO
IPC: D02J1/00
Filed: 1991-10-18
Abstract: PURPOSE:To stably obtain fancy yarn having clear and tightened stub parts by temporarily applying resistance to running multifilament yarn, wholly interlacing the stored formed yarn and then subjecting the interlaced yarn to fluid jetting texturing and bundling heat treatment. CONSTITUTION:Multifilament yarn (Y1) is subjected to fluid jet texturing with a fluid jet nozzle 4 while being fed at a constant overfeeding ratio between feed rollers 1 and take-off rollers 5. In the process, an intermittently acting resistor 3 is installed between the fluid jet nozzle 4 and the feed rollers. The yarn slacked between the resistor 3 and the feed rollers 1 in applying the resistance is sucked under a negative pressure to form resident yarn. Compressed air is simultaneously blown on the base of the resident yarn to interlace the resident yarn over nearly the whole length. The yarn is then subjected to fluid jet texturing with the fluid jet nozzle to intermittently form triple parts in the longitudinal direction of the yarn. The resultant yarn is subsequently heat- treated while being turned with an air swirling nozzle 7. Thereby, the objective fancy yarn is obtained.

Title: Numerical controller
Inventor: FUJIO MIKIO
IPC: G05B19/414
Filed: 1989-11-22
Abstract: PURPOSE:To avoid the repetition of the same operation by converting an operating signal to a program and storing it, and switching a signal sent out of a file decoding part or an operation history file generating part by a command from the outside. CONSTITUTION:An operation history file generating part 18 converts an operating signal and an action signal sent from a keyboard 3 and an input interface 13 to a symbol or a numerical value and sends them out, and also, generates an operation file by converting them to a program. A file control part 19 executes editing of the operation file generated by the generating part 18, and stores it in an operation file memory 16. This stored operation file is read out and decoded by an operation file decoding part 21 by a working program instruction. In this case, an input control part 22 switches and sends out a signal sent out of the decoding part 21 or the generating part 18 by a command from the outside. As a result, since the contents of the operation file of the memory 16 are decoded and transferred when necessary, it becomes unnecessary to execute the operation by the previous operation history, and the operability is improved.
