    Abstract: The present invention provides a holographic screen having high durability and high diffraction efficiency due to a modulated refractive index structure having a large refractive index change ”n. The holographic screen includes a diamond-like carbon (DLC) layer (22). The DLC layer has a modulated refractive index structure including a plurality of regions with a relatively high refractive index (n1) and a plurality of regions with a relatively low refractive index (n2) such that light projected from a projector onto the screen is deflected in the direction toward a observer and light coming from an object behind the screen is allowed to pass through the screen to travel toward the observer.

    Abstract: A polarization integrator comprising a polarization beam splitter (PBS)(51) for separating a light from a light source (1) into P-polarization and S- polarization, a first micro-lens (52), a 1/2 wavelength plate (53), and a second micro-lens (54), wherein the first micro-lens is disposed so as to condense P-polarization and S-polarization separated by the PBS to mutually different positions, the 1/2 wavelength plate is disposed at a position wher e the P-polarization is condensed to act to convert P-polarization into S- polarization, the second micro-lens acts to integrate S-polarization after passed through the 1/2 wavelength plate and polarization-converted with S- polarization not passed through the 1/2 wavelength plate, and at least one o f the PBS, first micro-lens, 1/2 wavelength plate and second micro-lens is formed by using a DLC film.

    Abstract: A bonded body of aluminum and silicon nitride firmly bonded to each other which is produced economically, and a light-weight component having an excellent lubrication characteristic as a mechanical component of an internal combustion engine of an automobile. The bonded body includes a base consisting of aluminum as its principal component and a member comprising a silicon nitride sintered body bonded substantially directly to the base. A base material (2) in a powder or bulk form containing aluminum as the principal component and a member (1) comprising a silicon nitride sintered body are put into a mold and are heated under pressure to mutually bond them.

    Abstract: A magnetism sensor comprises a substrate, a SQUID including a washer of an oxide superconductor thin film formed on a principal surface of the substrate, a hole shaped a similar figure to the washer at the center of the washer, a slit formed between one side of the washer and the hole and a Josephson junction by which portions of the washer at the both sides of the slit are connected across the slit. The magnetism sensor further comprises a superconducting flux transformer of an oxide superconductor thin film including an input coil arranged on the SQUID but isolated from the SQUID and a pickup coil arranged on the principal surface of the substrate far from the SQUID, which are connected in parallel and a magnetism shield which excludes flux penetrating into the Josephson junction of the SQUID.

    Abstract: There is disclosed a superconductor junction structure comprising: a first superconducting layer (1) of an oxide superconductor formed in a desired pattern on a substrate (10); a non-superconducting layer (3) of a non-superconductor formed on at least a part of the side faces of the first superconducting layer (1), a portion of the surface of the substrate (10) near the part, and a top face of the first superconducting layer (1); and a second superconducting layer (2) of the oxide superconductor formed on the non-superconducting layer (3), the non-superconducting layer being formed thin at the part, and forming a tunnel barrier. And further there is disclosed a process for fabricating a superconductor junction structure comprising: the first step of forming a first superconducting layer (1) of an oxide superconductor in a desired pattern on a substrate (10); the second step of forming a non-superconducting layer (3) of a non-superconductor formed on at least a part of the side faces of the first superconducting layer (1), a portion of the surface of the substrate (10) near the part, and a top face of the first superconducting layer (1) by depositing the non-superconductor from the above; and the third step of forming a second superconducting (2) layer of the oxide superconductor on the non-superconducting layer (2).
