Title: Melt spinning
Inventor: NAKATSUKA HAJIME
IPC: D01F6/62
Filed: 1983-04-08
Abstract: PURPOSE:When the high-speed melt-spinning of polyester is effected, the cooling air is blown to the yarn from the air-flow straighteners opposing to each other on both sides of the yarn path to effect uniform cooling of the yarn and prevent yarn breakage. CONSTITUTION:When polyester is melt-spun at a taking-up speed over 5,000m/ min, a couple of air-straighteners are set on both sides of the yarn path so that they oppose to each other and the surface from which the cooling air comes out becomes parallel with the rows of the nozzle holes to effect uniform blowing of the cooling air. If the nozzles are in two or more rows, their arragement is preferably zigzag in even-number rows.

IPC: H02K15/04
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To obtain a winder, in which the winding start part of an element wire can be securely retained by a winding frame. SOLUTION: A 1st main shaft 24 and a 2nd main shaft 26, which rotate synchronously on the same axial line, support a winding frame 28 and a gripper 60. On the way of the winding start part on the winding frame 28, a wedge opening 52 is formed as a gripping gap. The gripper 60 is pushed into the gripping gap. Wedge planes are provided on both the sides of the gripper 60 and the winding frame 28. The gripper 60 firmly presses the element wire to the winding frame through wedge action. The element wire can be surely retained by the winding frame and hence the slippage of the element wire and defective forms and film damages which are caused by the slippage can be avoided, so that productivity is improved.

Abstract: PURPOSE:To enable to reduce an Ag-plating layer in a leadframe in which Ag- plating is performed on the surface to improve soldering by sequentially laminating an Ni-primary plating layer, an Sn-Ni-Co alloy plating layer and a plating layer of metal including Ag. CONSTITUTION:After a substrate 1 made of phosphorus bronze is punched, pretreated such as degreased, pickled, an Ni-primary plating layer 2, an Sn- Ni-Co alloy plating layer 3 and an Ag-plating layer 4 are sequentially laminated on a semiconductor element stationary portion 5 and an internal lead terminal 6 by an electrolytic plating method. The Sn-Ni-Co alloy is required that the total of the content rates of Sn and Co is 20-90% and the content rate of the Co is 0.5-15% as well as the residue is Ni. Thus, the bondability of the Ag-plating layer is not decreased even by the high temperature heating in the packaging step such as plastic, and the decrease in the characteristics such as the discolor to the Ag-plating layer can be suppressed, and the reduction in the thickness of the Ag-plating layer can be accordingly performed.
