An object of the present invention is to provide a peptide vaccine for preventing and/or treating diseases caused by amyloid β-peptide, such as Alzheimer's disease. The present invention solves the above object by providing a peptide vaccine constructed by inserting a peptide having an amino acid sequence of a cell attachment motif of a cell adhesive molecule to a peptide which consists of a peptide having an amino acid sequence of multiagretope type T-cell epitope, which has been generated immunological memory, or a peptide including the same; an linker peptide; and a peptide having an amino acid sequence of a B cell epitope which is a specific region of amyloid β-peptide or a peptide including the same.

A magnetic recording medium based on the perpendicular magnetic recording system includes a substrate; a back layer which is formed on the substrate and which is formed of a soft magnetic material; an in-plane magnetized layer which is formed on the back layer and which has in-plane magnetization; and a recording layer which is formed on the in-plane magnetized layer and which has perpendicular magnetization, wherein the in-plane magnetized layer has a coercivity in an in-plane direction larger than a magnetic field generated by residual magnetization in a perpendicular direction of the recording layer. The influence on the reproduction output, caused by the mirror image effect of the soft magnetic back layer is reduced in wide range recording densities, thereby improving the resolution by decreasing the difference between the reproduction outputs of the magnetic recording medium at the low recording density and at the high recording density.

摘要:
A magnetic recording medium 100 comprises, on a substrate 1, a soft magnetic layer 3, a seed layer 5, and a recording layer 6 having an artificial lattice structure. The seed layer 5 is formed of Pd and one selected from the group consisting of Si, B, C, and Zr. Accordingly, the magnetic exchange coupling force of the recording layer 6 in the in-plane direction can be weakened. Minute recording magnetic domains can be formed in the recording layer 6, and the magnetization transition area is distinct as well. Thus, the medium noise is reduced. That is, reproduction can be performed with a low medium noise even when information is recorded at a high density. A magnetic storage apparatus, which is provided with the magnetic recording medium as described above, can achieve an areal recording density of 150 Gigabits/square inch.

A magnetic recording medium comprises, on a substrate, a soft magnetic layer, a first seed layer, a second seed layer, and a recording layer having an artificial lattice structure. The first seed layer contains oxide of Fe. The second seed layer contains one of Pd and Pt, Si, and N. The magnetic exchange coupling force in the in-plane direction of the recording layer is weakened by the first seed layer and the second seed layer. Accordingly, minute recording magnetic domains can be formed in the recording layer, and the magnetization transition area is distinct as well. Even when information is recorded at a high density, the information can be reproduced with low noise. A magnetic storage apparatus, which is provided with such a magnetic recording medium, makes it possible to achieve an areal recording density of 150 gigabits/square inch.
摘要:
An amorphous magnetic recording medium comprising a substrate and an amorphous magnetic layer, where a magnetic domain formation-controlling layer comprising a main phase and 1 to 3 kinds of discrete spherical isolating phases arranged horizontally in lines in the main phase or 1 to 3 kinds of discrete spherical phases vertically stacked one upon another in the main phase is formed on the top side or the bottom side directly or through at least one of other layers to bring the amorphous magnetic layer into a finer magnetic domain structure, can satisfy high density recording.
摘要:
A semiconductor integrated circuit that self-tests the skew margin of the clock and data signals in an LVDS. A clock signal CKB1 is held in flip-flop circuit 105 synchronously with checking clock signal A1. Checking pattern signal PAT_A is held in flip-flop circuit 104 synchronously with checking clock signal A2. When the skew margin of clock signal CKA_IN and data signal DA_IN are checked, the checking signal TCKA of flip-flop circuit 105 is input instead of clock signal CKA_IN, and the checking signal TDA of flip-flop circuit 104 is input instead of clock signal DA_IN. The timing relationship between clock signal CKB7 and checking timing signal A1 and the timing relationship between clock signal CKB7 and checking timing signal A2 are controlled independently by timing control circuit 109.
