In a photometry device, photopic vision luminance Lp is measured by a first luminance measuring unit including a first light filter 4 and a first photoelectric converter 5, and scotopic vision luminance Ls is measured by a second luminance measuring unit including a second light filter 6 and a second photoelectric converter 7. A calculation part 8 calculates mesopic vision luminance Lmes based on a measurement value (photopic vision luminance Lp) of the first luminance measuring unit and a ratio of a measurement value (scotopic vision luminance Ls) of the second luminance measuring unit to the measurement value (photopic vision luminance Lp) of the first luminance measuring unit. Consequently, the photometry device can improve measurement accuracy of the brightness (mesopic vision luminance) in mesopic vision.

A method of manufacturing a magnetoresistance element that can accurately sort out truely defective products from apparently defective products due to the manufacturing processes. Manufacturing processes for MR elements includes a MR element formation process, a magnetic field application process and an electric inspection process. In the magnetic field process, the magnetic field application is limited to a range within 75.degree. to the longitudinal direction of a MR element pattern. By performing the magnetic field application process before the electric inspection process, the anisotropic magnetic field due to a shape magnetic anisotropy of the MR element can be aligned almost in a fixed direction, defective products due to the manufacturing processes can exactly be sorted out from the apparently defective products in the electric inspection process, so that the yield rate can be improved.

This invention relates to a magnetoresistive element used for a magnetic sensor, etc. A ferromagnetic magnetoresistive element thin film is formed so as to be electrically connected to and so as to overlap the upper end portion of an aluminum wiring metal on a substrate. Through using a vacuum heat treatment with a temperature between 350.degree. and 450.degree. C., a Ni--Al-based alloy is formed at the overlapping portion. Therefore, even when a surface protection film of silicon nitride is subsequently formed by plasma CVD on the substrate, the alloy prevents the nitriding of the upper end portion of the aluminum wiring metal. Accordingly, the surface can be protected from moisture by the silicon nitride film without increasing the contact resistance between the magnetoresistive element thin film and the wiring metal. Instead of the Ni--Al-based alloy, other conductive metals such as TiW, TiN, Ti, Zr, or the like may be used. Also, the surface protection film may be a multi-layered film having a first film containing no nitrogen, such as a silicon oxide film, and a second film of silicon nitride film formed on the first film.

An air cleaner has a discharge electrode member, an intermediate electrode member, and a counter electrode member disposed opposed and spaced apart from each other. A voltage source is connected between the discharge member and the intermediate member for generating ionic wind. A further voltage source is connected between the intermediate member and the counter member for accelerating the ionic wind such that the gradient direction of the electric field between the discharge member and the intermediate member is identical to that between the intermediate member and the counter member.

A windshield wiper device including a blade rubber, a backing holding the blade rubber in place, a support metal fixture including support claws for supporting the backing, an arm supporting the metal fixture, a spring loading the arm such that the blade rubber is forced against the windshield of a vehicle, and drive means connected to the arm for moving the arm, the metal fixture, the backing and the blade rubber in oscillating movement. The spacing interval between the adjacent two support claws is maximized at opposite end portions of the blade rubber and becomes smaller in going toward the center thereof, and a higher load is applied to the support claws near the central portion of the blade rubber than to the support claws near the opposite ends thereof, to thereby effectively avoid separation of the blade rubber from the surface of the windshield.
