摘要： A tilt sensor includes a photodetector having a photosensitive plane and detecting a light beam in multiple areas and outputting detection signals representing its intensities and a tilt detector for generating a tilt error signal, including information about the tilt of a disk, based on the detection signals. The light beam forms a beam spot on the photosensitive plane. The beam spot includes a +first-order light area in which zero-order and +first-order light rays, diffracted by a track on the disk, are superposed, −first-order light area in which zero-order and −first-order light rays are superposed, and a zero-order light area which is sandwiched between the +first-order and −first-order light areas, includes neither the +first-order nor −first-order light ray, but includes a zero-order light ray. The photodetector generates the detection signals except for light entering an opaque area provided for at least part of the zero-order light area.

摘要： A Czerny-Turner spectroscope according to the present invention includes: a collimator mirror having a toroidal surface for reflecting a beam of light passing through an entrance slit to a plane diffraction grating; and a telemeter mirror having a cylindrical surface for reflecting and converging the beam of light reflected and separated by the plane diffraction grating to an exit. When a slit is placed at the exit, the straight generatrix is set substantially parallel to the exit slit. When a linear object (such as the separation channel of the capillary electrophoresis microchip) to receive a part of the spectrum of light reflected by the telemeter is placed at the exit, the linear object is set parallel to the straight generatrix. By this construction and configuration, the curving of monochromatic spectrum component at the exit is minimized, and the monochromatic light produced by the inventive Czerny-Turner spectroscope can pass the exit slit in full. Thus, when used, as the detector of a capillary electrophoresis microchip, stability and reproducibility of capillary electrophoresis measurements are achieved.

摘要： When a microchip is set on a tray and operation of an apparatus is begun, the microchip moves to feed position in order to be filled up with a buffer solution, where upon a sample is injected into this microchip. Thereafter the tray is located on a detecting position, so that a sample introduction voltage is applied between a sample reservoir and a sample waste reservoir for introducing the sample into a separation passage. Subsequently, the operation is switched to application of a separation voltage between a buffer reservoir and a drain reservoir, for beginning analysis. When the analysis has begun, a detector detects a migration pattern in the separation passage, so that a signal processing board data-processes the detected pattern.

摘要： A camera equipped with a focal point correction apparatus has a camera body including a film loading portion, a position detecting mechanism, an optical system including a picture taking lens, a shutter, a lens driving mechanism, a pressure plate, a light measuring device, a distance measuring device, a memory, a shutter driving mechanism, a release switch, and a control unit. The position detecting mechanism has a light projecting unit and a light receiving unit and is used to measure the position of the light-sensitive surface of the film in the direction of the optical axis. The focal point correction apparatus includes the position detecting mechanism, the optical system, the memory and the control unit. When a photograph is taken, focal point correction is carried out by determining a correction value for correcting the extension setting of the picture taking lens based on measurements of the position of the film carried out by the position detecting mechanism.

摘要： A shutter mechanism, employed in a camera, is provided having a pair of blade members pivoted about a point. The blade members are moved between a position where the light path is completely shielded and another position where light is allowed to pass through. Each of the blade members has a gear portion, and gear members transmit a driving force from a pulse motor to the gear portions to move the blade members toward and away from each other. Further, the width of the pulses to be applied to the motor is varied corresponding to the revolution of the motor, and the phase of the pulse is temporarily reversed corresponding to certain aperture values. Furthermore, a reverse rotation pulse is applied to the motor at the end of the revolution of the motor for preventing the motor from overrunning. When the blade members are moved to form the opening corresponding to a predetermined aperture value, another pulse is applied to the motor for the period of time corresponding to exposure time in order to hold the opening for the period of time.
