Title: Magnetic head
Inventor: UENO NOBORU
IPC: G11B5/23
Filed: 1987-10-30
Abstract: PURPOSE:To reduce the damage of a magnetic film and to improve the yield by forming one end part of a gap as a thin film where a track control groove is formed and making a thin film which has a curved surface part left at the time of thin film formation face the other end part. CONSTITUTION:A couple of substrates 1 which have magnetic films 4 formed previously from track formation grooves 2 to gap facing surfaces 3 are made to abut on each other so that the magnetic films 4 face each other; and the substrates are joined together with fused glass 7 to constitute the gap (g). The track control groove 6 is in the trapezoidal shape consisting of a linear part 6a crossing the gap (g) at right angles and a slanting surface 6b which slants to the gap (g) at both end parts of the linear part and reaches the flank of a magnetic head, but the shape, size, depth, etc., of the groove are freely determined. Further, the shape of the track formation groove 2 on the other side from the gap (g) is not specified. Thus, gap end sides which are sectioned by the track control groove are arranged on a reference surface side for writing, the polishing of the magnetic film is minimized, and the damage of the magnetic film is reduced.

IPC: B65H75/14
Filed: 1994-11-08
Abstract: PURPOSE: To remarkably improve the quality of a coil by eliminating a snarl due to scratches, dents, or linear displacement produced by friction or collision between the inner drum of a bobbin and the inner surface of the coil at the time when the bobbin is assembled. CONSTITUTION: An elastic body 8 provided between a bobbin-inner drum 2 with upper flange and a sleeve 3 is expanded when a bobbin is assembled, and when the bobbin is disassembled, the elastic body is contracted to contract the bobbin-inner drum 2 with upper flange diametrically inwardly. In order to disassemble the bobbin, fixing of the bobbin-inner drum 2 with upper flange to a bobbin-lower flange 1 is released. When the sleeve 3 is lifted up to raise the bobbin-inner drum 2 with upper flange along with it, engagement of upper and lower projections 9, 11 of the bobbin-inner drum 2 with upper flange with grooves 10, 12 is released. At this time, the elastic body 8 functions to contract the bobbin-inner drum 2 with upper flange which is cylindrically assembled, diametrically inwardly, and thus a gap is produced between the inner surface of a coil 5 and the bobbin-inner drum 2.

Title: Polyester film for magnetic recording medium and manufacture thereof
Inventor: UCHIUMI SHIGEO
IPC: G11B5/73
Filed: 1984-12-28
Abstract: PURPOSE:To obtain polyester film, having few rough protuberance, prominent in flatness and slidability, and good in light shielding property, by a method wherein the value F5 of degree of orientation of the surface of the film in the lateral direction thereof, the average refractive index and the light absorption rate of the film are specified within a specified range. CONSTITUTION:The light absorption rate of the film, before coating magnetic layer and having total thickness of 15mu, is specified so as to be 25% or more, in order to increase the light shielding property of the polyester film. In case the average refractive rate (n') is lower than 1.600, size change due to contraction caused upon the working process of the magnetic layer as well as using of magnetic tape is caused, however, the mechanical strength of the film is reduced in case it exceeds 1.610. The relation of the degree of surface orientation DELTAP, the average refractive index (n') and the F5-value should satisfy the formula; 0.002XF5+1.43Xn'-2.15>=DELTAP>=0.002XF5+1.43X-n'-2.17...(1). When comparison is effected in the same F5-value and the same material, the film, whose DELTAP satisfies above-described formula, is prominent in flatness and slidability while the rough protuberances on the surface of the film may be reduced remarkably.

Title: System for compressing amount of information of character pattern
Inventor: NISHIKAWA KATSUHIKO
IPC: G09G5/26
Filed: 1989-10-23
Abstract: PURPOSE:To prevent the quality of a character pattern from being deteriorated because deformation having a specified shape occurs when an enlarged inflection point train is formed on the basis of an inflection point generated by applying the character pattern of a comparatively small size by extracting the specified shape from the extracted inflection point and correcting the shape of the extracted inflection point.
