Abstract: PROBLEM TO BE SOLVED: To execute a reproduction operation strong to crosstalks without the need for an initializing magnet of a magneto-optical recording medium which reads information by forming double mask within the beam spot of a reproducing laser beam. SOLUTION: A ground surface layer 2 (SiN film), a first magnetic layer 3 (GdFeCo film), a second magnetic layer 4 (GdFe film), a third magnetic layer 5 (TbFeCo film) and a protective layer 6 (SiN film) are laminated in this order on a substrate 1.

Title: Inspecting apparatus of projecting length of lead wire
Inventor: TSUCHIYA KUNIHIRO
IPC: H01L21/66
Filed: 1991-03-06
Abstract: PURPOSE:To determine whether the projecting length of a lead wire is proper or improper on an automatic assembly line by detecting the difference in the horizontal position between a slide gauge butting against the lead wire and the other gauge by the amount of the length of the lead wire as the agreement or disagreement of an optical axis. CONSTITUTION:A heater wire 1 to which a lead wire 2 is pressure-welded is transferred to a projecting length inspecting process by an assembly line transferring system. Guide blocks 14a, 14b are moved to the heater wire 1 by air cylinders 15a, 15b, so that the lead wire 2 is accommodated in an arch- shaped groove of slide gauges 20, 21. The interval between the gauges 20 and 21 is adjusted at 16 to be slightly larger than the diameter of the lead wire 2. Then, as an assembly line main mechanism moves the heater wire 1 to the right, if the lead wire 2 is at the upper side, the gauge 20 butting against the lead wire 2 is moved, resulting in the difference in the horizontal position of the gauges 20, 21 by the projecting length of the lead wire 2. If the difference is within a set value, the optical axes of a light emitting part 26a and that of a photodetecting part, 26b of a transmission-type photoelectric switch 26 agree with each other, and the lead wire is judged as good.

Abstract: PURPOSE:To perform cutting length control with high accuracy by obtaining the ratio of the traveling distance of a material while being restrained by a final rolling mill to the traveling distance when released therefrom to carry out the position correction and tracking correction of cutting timing. CONSTITUTION:A cutting-timing arithmetic circuit operates the moving distance of a material from the point of time when the end of the material arrived at a reference point till when a starting command is given to a shear, based on a material speed, a set cutting length, and the lead speed ratio of the shear to the material. At this time, the pulses from a pulse oscillator between the detections of the front end or rear end of the material by each of a plurality of material detectors on the outlet side of a final rolling mill are counted, and the moving distances of the material per pulse while being restricted by the final rolling mill and after released therefrom are obtained by first and second operating means while further obtaining the ratio thereof by a cutting timing correcting means, to correct the traveling distance of the material. Also, the lead speed ratio is switched over depending on whether the material is restrained by the final rolling mill or released therefrom. Thereby, the cutting length control with high accuracy can be performed.
