    摘要: A manufacturing method for a magnetic recording medium is disclosed. By using the method, the anisotropic magnetic field (Hk) of an underlayer is improved, spike noise generated in the soft magnetic underlayer is suppressed, and the signal-to-noise ratio (SNR) is improved without employing a special layer configuration and without the need for complicated and expensive processing. A soft magnetic underlayer is formed by laminating a soft magnetic lower underlayer, a non-magnetic metal layer, and a soft magnetic upper underlayer in succession on a non-magnetic substrate. After forming the non-magnetic metal layer, its surface is exposed to a gas containing between 2 and 100 at % oxygen. A perpendicular magnetic recording layer is formed on the soft magnetic underlayer.

    摘要: A thermal transfer type image formation device employs a new regeneration method for reconditioning ink sheets employed in the thermal inking process. The ink sheet has a transparent base layer, which also serves as a dielectric layer, an ink layer and a transparent conductive layer, functioning also as an electrode, on a side of the base layer opposite the ink layer. A fixing device is provided for the transfer of photoconductive powder ink to bare areas of the ink sheet to be rejuvenated. A bias voltage is impressed on the photoconductive powder ink, and the photoconductive powder ink which comes in contact with bare areas becomes conductive when exposed with light through the transparent conductive layer and ink adheres to the base layer due to an established electrostatic force between the ink and the conductive layer electrode on the light exposing side of the ink sheet. After the powder ink has been selectively supplied to the bare areas, the ink sheet is then regenerated by heating the sheet melting and thereafter hardening the powder ink.

    摘要: When emitted light from LED 31 is incident on photodiodes 32 and 33 with luminance Pa and Pb, currents ia and ib are generated according to luminance Pa and Pb. When outside light is incident through the finger tissues on photodiodes 32 and 33 with luminance Pc, current ic is produced. The current i1 (=ia+ic) generated by photodiode 32, and the current i2 (=−ib−ic) generated by photodiode 33, are added at node X, and the current ic corresponding to outside light is thus cancelled. In addition, photodiodes 32 and 33 are disposed at different distances from LED 31. As a result, the current flowing to opamp 34 is current ia corresponding to luminance Pa because luminance Pb is extremely low. The opamp 34 then applies a current voltage conversion to generate pulse wave signal Vm.
