    摘要： A self-biasing magnetostrictive element (10) for use in a magnetomechanical EAS marker is a strip of amorphous alloy material distributed throughout the bulk of the amorphous alloy strip. The crystalline particles (12) are magnetized to bias the amorphous alloy strip (14) to resonate in response to an interrogation signal. The crystalline particles (12) are formed by heat-treating the amorphous alloy strip (14) at a temperature above the Curie temperature of the amorphous alloy in the presence of a longitudinal magnetic field. The alloy strip (14) is then cross-field annealed at a temperature below the Curie temperature of the amorphous alloy to form a transverse anisotropy in the amorphous bulk of the alloy strip (14). A preferred alloy composition includes iron, cobalt, niobium, copper, boron and silicon.

    摘要： A returning light beam emitted by a light source (101) and reflected by an optical disk (106) is separated by a half mirror (102), and partitioned and deflected at a hologram (109) into a light beam passing a first region and a light beam passing a second region. The light beam passing the first region is received by a plurality of photo-detectors (107), and the aberration is detected by comparing the resulting signals. Based on the aberration detection, the aberration of an optical system can be reduced by driving an aberration correction element (104) in real-time.

    摘要： A back electrode (6), linear hot cathodes (7) as electron beam sources, and an electrode unit (8) are placed on and fixed to a rear case (4). On the other hand, wire electrodes (9) fixed to a grid frame (10) are positioned relative to stripes of a phosphor screen (2) and are then placed on and fixed to a supporting frame (11) placed in a front case (3) using stud pins (21). According to such a configuration, when the front case and the rear case are bonded and are thus fixed, the position shift between the phosphor screen (2) and the wire electrodes (9) can be suppressed within a tolerance. As a result, a flat-type display apparatus that can display excellent images can be provided.

    摘要： A position detecting element that enables a position to be detected at high speed and high precision, and a range sensor using the same. The position detecting element is provided with a PIN photodiode array (1) having n segments and a parallel arithmetic processing portion (2) that calculates the segment having maximum intensity by comparing n outputs from the segments of the PIN photodiode array (1). The range sensor includes a light source by which the object to be measured is irradiated by optical beam, a lens that gathers rays of the reflected light from the surface of the object to be measured and the position detecting element mentioned above that detects the position of the light gathered by the lens.
