Title: Combined filament yarn of different shrinkage having change in heat shrinkage in longitudinal direction
Inventor: FUJIWARA TSUGUO
IPC: D03D15/567
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To obtain the subject combined filament yarn of different shrinkages which is a polyester multifilament yarn, having thick and thin parts on the high heat shrinkage side in the yarn and capable of forming the slub- or neplike unevenness of' thickness by heat treatment by increasing the heat shrinkage percentage of the thick parts of the yarn from that of the thin parts. SOLUTION: This combined filament yarn comprises a yarn A' on the high shrinkage side, constituting the combined filament yarn and capable of more shrinking than a yarn B' on the low shrinkage side by an extent corresponding to the difference between both the yarns A' and B' in heat shrinkage. The yarn B' is kept in a state of slackened constituent filaments as compared with the yarn A'. When the yarn A' on the high shrinkage side is shrunk, a thick part 1' of the yarn is more shrunk than a thin part 2' of the yarn. Thereby, the slackness of the yarn B' on the low shrinkage side in the thick part 1' is increased from that of the yarn B' on the low shrinkage side in the thin part 2'.  As a result, the thickness of the combined filament yarn in the thick part 1' appears to be greater than that of the thin part 2' and effects of appearance in a slublike part S or a neplike part N are expressed.

IPC: G05F1/10
Filed: 1986-02-17
Abstract: PURPOSE:To prevent a large current from flowing in a switching means and the damage to said means by opening the switching means at the time of generating a short circuit. CONSTITUTION:When a connection part (a) is shorted at the time of conducting a solenoid 1 as broken lines show, the voltage of a connection part (b), which is impressed on part of an exclusive OR circuit 12, approximately comes to a zero level. Accordingly a signal H is impressed on the other end of the exclusive OR circuit 12, and its output becomes H. When said output at a level H continues in the prescribed time, a short decision circuit 15 decides that the continuity is a short, and opens a relay 14. Thus the conduction of a transistor 2 is stopped to open the transistor 2, whereby a large current flowing to the transistor 2 can be prevented and its damage can be also prevented even if a short occurs.
