    Abstract: PROBLEM TO BE SOLVED: To realize long-period driving reliability by suppressing a sticking phenomenon in long-period driving caused by structural asymmetry of flank parts of an inter-pixel groove. SOLUTION: A 1st obliquely vapor-deposited alignment film 43A is formed by vapor deposition on the 1st flank of the inter-pixel groove in a thickness-directional section of a pixel electrode substrate 40 and a 2nd obliquely vapor-deposited alignment film 43B is vapor-deposited on the 2nd flank facing the 1st flank. Consequently, the film structure of both the flanks of the inter-pixel groove 50 in the section becomes symmetrical to suppress the sticking phenomenon in long-period driving caused by structural asymmetry of the flank parts of the inter-pixel groove.

    Abstract: PROBLEM TO BE SOLVED: To provide a projection optical system and a projection display system, which maintain a sufficiently low black level and realize a high contrast even with a high-luminance optical system with a small F number by using a quick-response reflection type liquid crystal display element, which has saturation of liquid crystal transmissivity with a low voltage even when a liquid crystal layer is thin and can be manufactured even to a small pixel size through a normal pressure-proof process, for a vertical alignment liquid crystal display device. SOLUTION: The reflection type liquid crystal display device 23 is so adjusted that the thickness (d) of the vertical alignment liquid crystal layer is ≤2 μm and the refractive index anisotropy Δn of a vertical alignment liquid crystal material is ≥0.1. Then the transmissivity of the liquid crystal is easily saturated with a voltage of 5 to 6 V to enable low-voltage driving and greatly improve the transmissivity and further the black level which is considered to be proportional to the square of the liquid crystal layer thickness is suppressed low to realize a high contrast and high luminance with a small F number even when the F number of an optical system is ≤3, or small.

    Abstract: PROBLEM TO BE SOLVED: To provide an electrophoresis display device capable of displaying an information by an electric signal inputting with handwritten input and maintaining a sample on a display. SOLUTION: An electrophoresis display device E1 comprises a microcapsule 3 sealing a dispersion system of electrophoresis particles and a dispersion medium.

Written input and erasure are carried out by a potential difference charged between a common electrode 4 forming an electric field and an input pen 7. Further a paper sheet 29 is held between the display portion and the carrier 28 by force generated from magnetism between the carriers 28 consisting of the ferromagnetic material or the paramagnetic material and the magnetic layer 6.

    Abstract: PURPOSE:To obtain a magnetic field detecting element which is suitable for high-density recording and reproduction by forming extremely thin magnetic wires at specific intervals and by placing non-magnetic layers between the magnetic wires. CONSTITUTION:Magnetic wires 2 made of Co, Fe, Ni and an alloy of these are formed in very small dimensions, 0.5-100nm wide (d), 1-100nm thick (t) and 1-10,000nm long (1). The magnetic wire 2 are located in a plane with non- magnetic layers 3 made of Cu, V, Ru and Cr put between. The width D of the non-magnetic layer 3 is so set at 0.5-100nm as to generate antiferromagnetic bonding between the magnetic fine lines and the non-magnetic layers. By this method, a magnetic field detecting element can be obtained which is very small in size but which is very much suitable for high-density recording and reproduction and has such a characteristic that an electric resistance may change effectively to an outside magnetic field. With this element, a high-density magnetic reproducing system and a very small magnetism observation equipment can be obtained.

    Abstract: PURPOSE:To inexpensively improve magneto-optical characteristics by forming artificial lattice films formed by alternately laminating Co layers and Pt layers and/or Pd layers on a substrate in a gaseous Kr and/or gaseous Xe atmosphere of a specific gaseous partial pressure. CONSTITUTION:The artificial lattice films alternately laminated with the Co layers and the Pt layers or the Co layers and the Pd layers of the three; the Co layers, the Pt layers and the Pd layers are formed on the substrate. These artificial lattice films are formed by sputtering in the gaseous Kr and/or gaseous Xe atmosphere having 2X10 to 3X10 Torr gaseous partial pressure. The total thickness of such artificial lattice films is specified in a 50 to 800Angstrom range. The thickness of the Co layers is specified to 2 to 8Angstrom , the thickness of the Pt layers to 3 to 40Angstrom and the total thickness to 50 to 400Angstrom particularly in the case of the Co-Pt layers. The thickness of the Co layers is specified to 1 to 9Angstrom , the thickness of the Pd layers to 2 to 40Angstrom and the total thickness to 50 to 800Angstrom in the case of the Co-Pd layers. The film quality is improved in this way and the squareness ratio and coercive force are improved.

    Abstract: PURPOSE:To make the Kerr angle of rotation large and to ensure a good squareness ratio by a method wherein a plurality of atrificial lattice magnetic films in which Co layers and Pt layers have been formed alternately are formed via transparent dielectric layers. CONSTITUTION:A recording layer 4 which has been sandwiched between dielectric layers 2, 3 for enhancement use is formed on a transparent substrate 1; in addition, a reflecting layer 5 composed of a metal is formed. For the recording layer 4, a plurality of Co-Pt artificial lattice magnetic films 6 and transparent dielectric layers 7 are formed alternately, and its whole film is made large. The Co-Pt artificial lattice magnetic films 6 are not formed as one continuous thick film, but have a structure which has been divided into a plurality of layers between which the transparent dielectric layers 7 are laid. Thereby, while the total sum of the whole thickness of the Co-Pt artificial lattice magnetic films 6 is made large, the squareness of a magnetization curve can be kept in a good state.
