摘要： An objective lens for two or more types of optical discs of different standards is provided. A surface of the objective lens is formed with a diffracting structure, and has an inner area including an optical axis and an outer area. The outer area is configured such that part of a first beam (having a first wavelength for a first optical disc of relatively lower data density) passed through the zones will be substantially in phase (within a prescribed phase difference) with part of the first beam that passed through the inner area. A convergence angle θ of part of the first beam incident on the outermost part of the inner area measured after emerging from the objective lens and a design numerical aperture NAref for the first optical disc satisfy: 0.9

摘要： A phase shift element having a central area (for transmitting part of an incident laser beam in the vicinity of the beam central axis) and a first area (giving the laser beam incident thereon a phase difference π relative to a beam passing through the central area) is placed on an optical path between a laser light source and a polygon mirror of a scanning optical system. The scanning optical system including such a phase shift element is installed in a printer. By the effect of the phase shift element, the intensity of side lobes (several rings of light accompanying the main beam) is prevented from exceeding a threshold value even when optical surfaces of an imaging optical system of the scanning optical system have certain microscopic undulations, by which black stripes occurring in halftone printing can be eliminated.

摘要： A pain inferring device for designing a shape giving a subject as little pain as possible when the subject touches the shape. The pain inferring device includes an input unit, an output unit, a main control unit, a learning storage unit, and a neural network. The neural network learns the relationship between the input value of shape data and the output value of the data on the degree of pain when a subject touches a shape. By the learning, an input/output function (namely, the coefficient of coupling of neurons in layers) representing the relationship between the input and output values is defined and stored in the learning storage unit. When the shape data is inputted through the input unit, the neural network infers the degree of pain by using the function stored in the learning storage unit.

摘要： A relative rotational angle of a rotary body is measured with respect to a reference angle. First openings are arranged about the circumference of a disk, which rotates integrally with the rotary body, at predetermined pitches. A first detecting element detects the first openings and generates a first binary code. The relative rotational angle of the rotary body is computed in accordance with the first binary code. A second detecting element detects the second openings and generates a second binary code. The reference angle of the rotary body is computed and reset in accordance with the second binary code. Third openings are concentrical with the first and second openings. A third detecting element detects the third openings and generates a third binary code. The reference angle is determined based on the combination of the first and third binary codes.

摘要： A rotor is fixed to a steering shaft to rotate with the steering shaft, and outer and inner slits are formed along different circles on the rotor. Outer and inner sensors, which detect the presence or absence of the slits, generate reflective codes and are located next to the rotor. Stored pattern data that matches the reflective code is used to determine the rotational angle. Alternatively, if the pattern data does not match the reflective codes, the rotational angle of the steering shaft is computed on the basis of the reflective codes.

摘要： A scanning optical system is provided with a semiconductor laser, a polygonal mirror, which deflects a beam emitted from the semiconductor laser, an f&thgr; lens for converging the beam deflected by the deflector onto a surface to be scanned, and a diffractive surface between the polygonal mirror and the surface to be scanned. The diffractive surface compensates for a lateral chromatic aberration caused by the f&thgr; lens. Further, the diffraction efficiency of the diffractive surface on an optical axis of the f&thgr; lens is smaller than that of a peripheral portion to cancel a power variation due to a variation of the light quantity transmitted through the scanning lens.
