Title: Handle member for bag, and its manufacture
Inventor: OGATA KO
IPC: A45C13/26
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To simplify the attaching structure for a bag by a method wherein, at both ends of a band, an attaching rod being formed into a bar-shape, which protrudes from the center of the width of the band in the extending direction, are provided, and the attaching rods are bonded on the side wall of a bag under a state being pinched. SOLUTION: At the rear end on the right side, an engaging part 13 is formed by a protruding-recessed die 15. When a handle member P is discharged to the left side, an attaching shaft 3 at the rear end is held under a state wherein the attaching shaft 3 is fitted in an opening part 16 of a metal die 8 for injection molding, under a state being held by a holding die 17. Under such a partially remaining state, the protruding- recessed die 15 returns, and when an injection is performed again, a material flows into the engaging part 13 of the remaining attaching shaft 3, and is integrally connected to it, and a new hand member P is formed. By repeating this process in order, the handle member P is continuously formed, and taken up by a drum. The handle member P can be conveniently used by a length being required, by cutting it at a specified location while unwinding it.  On the internal surfaces of both side walls of a bag V, rear papers 7, 7, are affixed, and the attaching shafts 3, 3 are fixed by pressing. The attaching structure for a bag is simple, and the handle member P is suitable for a mass-production, and can be manufactured at a low cost.

Inventor: MAEZAWA KATSUHIKO
IPC: D01G1/08
Filed: 1978-12-22
Abstract: PURPOSE: Stretch-breaking roller in every position is made it possible to start and stop and as the stretch-breaking rollers in the stretch-breaking stage make slow- starting, the tow in the drawing stage is gradually nipped with nipping rollers, thus preventing the mass yarn breakage and making it possible to thread at every position.  
     CONSTITUTION: Tow 12 before threaded is hung down to drawing rollers 4 and 5 but the nipping rollers 2 and 5 are kept not pressed to rollers 1 and 4 respectively. Further, tow 12 is nipped with stretch-breaking roller 6 that is stopping. Then, the stretch-breaking roller 6 is made to slow start so that the spinning speed comes to the steady one within 1W5 seconds after the start and the tow 12 is nipped with rollers 1 and 4 at the drawing stage. When necessary, the nipping pressure at roller 6 is lowered than at the steady state for 1W5 seconds after the spinning start to loosen the hold of tow 12, thus preventing the mass breakage of tows.

Title: Aligning method of wafer
Inventor: KOMORIYA SUSUMU
IPC: G03F9/00
Filed: 1983-08-31
Abstract: PURPOSE:To obtain a method through which a wafer and a mask are fast stuck and separated easily by projecting the central section of the wafer to bring the wafer into contact with the mask and slowly flattening the wafer so that a closely adhesive surface with the mask spreads to a peripheral section from the central section of the wafer. CONSTITUTION:When the wafer and the mask are fast stuck, air is blown off from air blow-off ports 12 and air is sucked from air suction ports 13, the central section of the wafer 21 is projected upward, and the peripheral section is adsorbed onto a wafer base plate 11. Consequently, when the wafer 21 is projected and the mask 22 is placed on the wafer 21, both are in contact only in the central projecting section of the wafer 21, and air is not brought to a sealed state between both, thus easily positioning the mask 22 at a predetermined position on the wafer 21. When the blow-off of air and the suction of air are stopped and the projecting deformation of the wafer 21 is released, the wafer 21 and the mask 22 shift easily to the closely adhesive state to the peripheral section from the central section.
