摘要： The present invention provides a touch panel having pluralities of projections, each of the projections having a predetermined shape, formed on inner surfaces of a lower substrate and an upper substrate, respectively. The projections being formed in at least two directions with a substantially periodical pitch that is shorter than any wavelength of visible light. The touch panel can also include a lower transparent electrode and an upper transparent electrode formed over the inner surfaces of the lower substrate and the upper substrate having the pluralities of projections, respectively. The cross-sectional area of each of the projections parallel to the outer surface of the lower substrate is configured to decrease continuously from bottom to top of the projection. The same applies to the combination of each of the projections, the bottom and a top thereof, and the upper substrate. Accordingly, this structure reduces the light reflection and diffraction at the boundary between an air space and the transparent electrode, thereby providing a resistive contact-type touch panel or a electrostatic capacitive coupling-type touch panel having high light transmittance.

摘要： A coordinate input device is associated with a liquid crystal display to detect a touch or contact thereon. A transparent board is arranged on the screen of the display to provide a coordinate input surface having a substantially rectangular shape. At least one vibration detector (e.g., a microphone or piezoelectric element) is attached onto the board to detect vibration or sound that occurs when a position input member is brought into contact with the coordinate input surface at an arbitrary input position. The input position is represented as one-dimensional coordinate based on outputs of two vibration detectors, or it is represented as two-dimensional coordinates based on outputs of three vibration detectors. Thus, the manually designated input position is detected and is electronically displayed on the screen of the display. As the position input member, it is possible to use a pen, a fingernail, etc.

摘要： A small and inexpensive optical head for detecting a recorded signal, a focusing error signal and a tracking error signal, and an optical memory device utilizing the optical head. A diffraction device (103) is provided having two chirped grating regions (103A, 103B) for dividing a light beam from an optical recording medium (105) and directing the divided beams toward four band-shaped photoelectric transducers (106) and an astigmatism generator formed by the diffraction device (103) and a positive lens (102). The four photoelectric transducers are positioned in a plane inclined with respect to the optical axis of zero-order diffraction light, and the longitudinal axes of each of the band-shaped photoelectric transducers are radially arranged relative to the optical axis.
