Filed: 1982-07-14
Abstract: PURPOSE:To improve the corrosion resistance of a magnetic recording medium, by exposing a metallic ferromagnetic thin film formed on a polymer film substrate into an oxidative glow discharge atmosphere while keeping the thin film under a magnetized state in one direction and therefore producing a corrosion-resistant oxide evenly on the surface of a magnetic layer. CONSTITUTION:A substrate 1 containing a metallic ferromagnetic thin film of Co, etc. is fed out through a roll 6 onto a polymer film and then magnetized in one direction by an AC electromagnet of a commercial frequency or a high frequency or a DC electromagnet 8. The magnet 8 can substitute a permanent magnet if the characteristics, the coercive force in particular, is decided for a subject magnetic layer. Under such conditions, the substrate 1 is shifted along a rotary roll 2, and at the same time, rod-shaped glow processing electrodes 3 and 4 extending around the roll 2 and in the roll width direction are alternately insulated. Then the devices connected to each other to obtain the same potential are used to perform an oxidizing process with control carried out to obtain a fixed level of pressure with use of a discharging matter of O2, etc. Thus an oxide is formed evenly on the surface of a magnetic layer. This process improves the corrosion resistance and prevents the clogging of a magnetic head for a magnetic tape.

Title: Pressure fixing device
Inventor: NITANDA HIROSHI
IPC: G03G15/20
Filed: 1979-09-26
Abstract: PURPOSE: To make possible matte copying and improve the durability of fixing rollers by subjecting the surface of rollers in contact with toner images to roughening treatment and disposing part of back-up rollers nonparallel with these rollers.  
     CONSTITUTION: The toner images of recording paper P are pressure-fixed by a fixing roller 1 and pressure roller 2, at least one whereof is driven. The peripheral surface of this roller 1 is subjected to roughening treatment in such a manner that it assumes a rough surface of micro-unevenness of 5W500μ mean diameters and 2W 50μ mean depths, thus the smoothing of the recording paper P by the pressure contacting of the mirror-finished top surface and the production of gloss are prevented. On the other hand, the rollers 1, 2 and the back-up rollers 3 in contact with the roller 1 are installed mutually parallel, by which the abrasion of the unevenness of the roller 1 caused by the polishing action owing to the slips between the rollers is prevented and the durability is thus improved. Part of rollers 4, 5 of the back- up rollers are nonparallel to the rollers 1W3 to uniformalize the pressure between the rollers 1, 2. The similar results may also be obtained even by subjecting both rollers 1, 2 to surface roughening.

IPC: G11B11/105
Filed: 1991-05-28
Abstract: PURPOSE:To eliminate a need of accurate position adjustment and to eliminate an influence of secular change by dividing the polarization component of a reflected signal into two and separating this light in two directions and receiving it by two photodetectors to detect a tracking error signal. CONSTITUTION:Signal light reflected from an optical recording medium is branched into two by a polarizing beam splitter 1, and branched signal line is received by two-divided photodetectors 61 and 62 of a first light detecting means 6 to generate a focus error signal. The other polarization component reflected in two directions is reflected by a polarizing film and is received by two photodetectors 71 and 72 of a second light detecting means 7 to generate the tracking error signal. Therefore, it is unnecessary to accurately adjust the positions of two light detecting parts with respect to optical axes of light reflected in two directions, and an optical pickup is realized where the adjustment work is simplified and which is not effected by the secular change.

Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To improve a tool life not only in continuous cutting but also in discontinuous cutting by allowing steel to contain Al, B and N and forming depositions of AlN on a cutting tool face at the time of cutting. SOLUTION: As for the contents of Al, B and N in the steel, preferably, by weight, 0.01 to 0.15% Al, 0.0030 to 0.020% B and 0.0050 to 0.020% N are controlled. Al is needed for the deoxidation of the steel and is also needed for forming AlN depositions on a tool face at the time of high speed cutting. B and N are bonded in the steel to form into BN, which is brought to react with Al in the steel on the tool face at the time of high speed cutting to form into AlN and is deposited on the tool face. Moreover, though it generally says that Ca-contg. steel has tool wear suppressing effect at a high speed, Ca is bad in the yield in continuous casting, and there is not composite effect by the addition of Ca, and, therefore, Ca is not substantially contained. Concretely, Ca content is preferably controlled to <=0.0010 wt.%.
