Abstract: PURPOSE:To increase production yield, by forming a recording layer by masking both end parts of a magnetic tape in the width direction of a film base material and vapor-depositing a magnetic material so as to produce a blank part and then cutting the blank part to eliminate the uneven roll-up of the magnetic tape. CONSTITUTION:A base material 7 of polyethylene terephthalate film, etc. for magnetic tape is shifted along the outer circumference surface of a cooling rotary drum 12 by a supply reel 8 via a free roller 9 and an expansion roller 11. Then the current of magnetic metallic steam 15 given from an evaporation container 14 is vapor-deposited by a mask 13 and in a prescribed range of incident angle. In this case, a mask 16 close to the curved surface of the drum 12 is set across the drum 12 so as to cover the both end surfaces of the material 7 to prevent the vapor deposition of the vapor current on the both end surfaces. The material 7 with which the vapor deposition is cover is fed to a cutting mechanism part 17 via the rollers 11 and 9 to be cut at its both ends. Then both the magnetic film formed part and unformed part are rolled up to reels 19 and 18 via the roller 9. Then the vapor-desposited film is formed at both ends of the material 7 to prevent the uneven roll-up of the magnetic tape which is caused by the complicated flow of the steam current.

Filed: 1987-03-25
Abstract: PURPOSE:To measure an angle with high accuracy by a simple mechanism, by extracting the characteristics of the interference patterns of two lights in order to arrange the equiphase surfaces of two luminous fluxes on a photodetector. CONSTITUTION:In order to measure the relative angular change between a fixed object and a moving object, a light source is mounted on one object and a receiving system is mounted on the other object. In the receiving system, the lights 6', 6' from light sources are received by condensing lens 8, 8' to set two systems of light paths and mutually overlapped on a light receiving element 12 through a reflecting mirror 10, a light synthesizer 11 and a slit 13 to be allowed to interfere with each other. Since the equiphases of the components of the lights 6', 6' do not perfectly coincide with the interference pattern on the element 12 at that time, concentric circular bright parts (or dark parts) 14', 14 and a dark part (or bright part) 15 appear. When the angle (incident angle) theta of a reference axis 5' and the axes of the lights 6', 6' changes, the brightness of the bright part 14' changes to cosphi times (phi is formula phi=2pidsintheta/lambda-2piN and N is a number of interference amplitude max. points) and the same amplitude change as that when equiphases are arranged is obtained.
