IPC: B65H23/198
Filed: 1982-06-07
Abstract: PURPOSE:To make it possible to perform winding-up at a prescribed tension for a long period, by measuring previously as a pattern the mechanical loss corresponding to the rotational speed of a motor in a wind-up section, memorizing the pattern, and adding the current value of the mechanical loss to a set value of tension. CONSTITUTION:As a material 13 is wound up onto a wind-up section 1, the diameter of the winding changes. The change of the diameter is detected by a wind-up diameter detector 12, and a field current controller 10 is controlled via a wind-up diameter signal generator 11 so that the field current is increased for the decrease in the revolutional frequency of a direct current shunt motor 4 resulting from the increase in the winding diameter. The armature current of the motor 4 is controlled via a direct current power source generator 6 by an armature current controller 7 into which a tension setting signal of a tension setting apparatus 8 is inputted. Further, a compensation setting apparatus 9 is provided that contains a memory for memorizing a mechanical loss current pattern corresponding to the rotational speed of the motor 4, and the value of the output of the apparatus 9 plus the output of the setting apparatus 8 is applied to the controller 7.

Title: Method for winding bind around work
Inventor: MIURA MORIMICHI
IPC: H02K1/27
Filed: 1994-05-12
Abstract: PURPOSE:To wind a bind firmly around a work by previously heating or cooling the work or the bind so that the tension of the bind increases when the wound work is returned back to the working temperature as compared with the tension immediately after winding. CONSTITUTION:A bobbin 9 wound with a glass fiber 8 is fixed to the rotary shaft of a motor 13 and the glass fiber 8 is fixed to a work 2 through rollers 6,...,3. The glass fiber 8 is impregnated with a thermosetting resin 10 by means of the roller 5. The iron work 2 is immersed into liquid nitrogen in a vessel 1 at a working temperature of about 20 deg.C and cooled down to -19.6 deg.C thus shrinking the volume of the work 2. Subsequently, the liquid nitrogen is removed and the work 2 is returned back to the working temperature thus recovering the volume. When a bind having volume variation rate higher than that of the work 2 at the normal temperature or above is used, the bind is heated and wound around the work and then they are returned back to the normal temperature. In either case, the bind is wound firmly around the work.

Title: Photomask
Inventor: ENDO HIDEAKI
IPC: G03F1/00
Filed: 1985-05-13
Abstract: PURPOSE:To prevent the degradation of the precision of an autoalignment mark by providing an index part having distinct edges and a shielding part extended surrounding the index part. CONSTITUTION:When the auto-alignment mark is scanned with a laser beam, diffracted lights b2-b4 are generated. The diffracted light b1 in a shielding part 22 has the intensity changed with time because it interferes with a reflected light b2 from a wafer. The intensity of the diffracted light b3 of an index part 21 is not changed because it does not interfere with the reflected light from the wafer. Consequently, intensities of photoelectric converted signals S2, S4, and S6 are not changed with time and are stable though those of photoelectric converted signals S1, S3, S5, and S7 are changed with time. Only edge signals S2, S4 and S6 which are not affected by the interference due to the reflected light from the wafer and have stable intensities are used to measure intervals of marks, and precise auto-alignment is performed. Thus, the precision of auto- alignment is improved.
