Abstract: An optical system for an optical head of an optical disc drive is capable of using first and second discs, protective layer of the second disc being thicker than that of the first disc, a data density of the second disc being lower than that of the first disc. A light source selectively emits first and second laser beams having first and second wavelengths, respectively. An objective lens converges the first and second beams on the first and second discs, respectively. The second beam is incident on the objective lens as diverging light, and the first beam is incident on the objective lens as a beam of which degree of divergence is smaller. A diffraction lens structure is formed in the high NA exclusive area, which compensates for aberrations of a portion of the first laser beam, and causes aberrations to a portion of the second laser beam passed therethrough.

Abstract: 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.

Abstract: 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.

Abstract: Disclosed is an objective lens of an optical pick-up that converges light beams of two different wavelengths onto recording layers of optical discs of two different recording densities, respectively. The objective lens includes a refractive lens whose one surface is divided into a common area through which a light beam of a low NA, which is necessary and sufficient for an optical disc having low recording density, passes and a high NA exclusive area through which a light beam of a high NA, which is necessary only for an optical disc having high recording density, passes. A diffractive lens structure is formed in both the areas. The diffractive lens structure in the common area maximizes the diffraction efficiency of the first order and that in the high NA exclusive area maximizes the diffraction efficiency of the second or third order at the wavelength corresponding to the optical disc having high recording density.

Abstract: An optical system of an optical pick-up includes a light source portion that selectively emits a first laser beam (shorter wavelength) and a second laser beam (longer wavelength), and an objective lens for converging the first laser beam onto a first optical disc and for converging the second laser beam onto a second optical disc. The second optical disc has lower recording density and a thicker cover layer than the first optical disc. The divergence of the second laser beam incident on the objective lens is larger than that of the first laser beam, correcting one part of spherical aberration caused by a difference in thickness of the cover layer. A diffractive lens structure is formed on a surface of the refractive lens so that the residual part of the spherical aberration is corrected by switching the wavelength of the laser beam.

Abstract: 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.
