摘要:
A magnetic resonance imaging apparatus includes a movement unit which moves a subject placed in a static magnetic field, a collector which collects data corresponding to a magnetic resonance signal emitted from the subject, a detector which detects a position of a particular section of the subject in the static magnetic field, a reconstruction unit which reconstructs an image, based on the collected data, when the detected position falls within an allowable area, and a controller which controls the movement unit to compensate for a deviation of the detected position from a reference position.

According to a Magnetic Resonance Imaging (MRI) apparatus, a scanning-parameter limit calculating unit creates examination information that represents scanning conditions for collection of magnetic resonance signal data based on scanning parameters set by an operator; a scanning-condition edit/scan positioning unit creates a time chart that indicates the type and a sequential execution order of an event to be executed when collecting magnetic resonance signal data based on the examination information created by the scanning-parameter limit calculating unit, and causes a time-chart display unit to display the created time chart.

A display device includes: a display element for showing information as a screen image; and an ornamental member disposed on a display surface of the display element and having a shape corresponding to the screen image. The ornamental member includes a light transparent element and a light nontransparent element. The screen image includes a designed image on a position of the display surface corresponding to the light transparent element. The display element outputs a screen image light from the display surface. The screen image light corresponding to the designed image passes through the light transparent element so that the screen image light is outputted from the ornamental member to the display side.

A lens array is arranged in front of the screen of an image display at a distance of S1. The lens array consists of lenses having focal lengths f1 and f2. The focal length f1 and f2 and the distance S1 determine the forming positions of first and second imaging planes. The first imaging plane is formed at a position of distance S3 from the lens array and the second imaging plane is formed at a position of distance S2. More specifically, a pixel on the screen is imaged as a first imaging element of the first imaging plane at a position of S1+S3 form the screen and a pixel on the screen is imaged as a second imaging element of the second imaging plane at a position S1+S2 from the screen. A viewer can attain stereoscopic feeling when viewing them.

An information processing system has a plurality of information processing units. Each information processing unit has a system console interface control unit (SCI) connected to an information processing unit body (COM) and a service processor (SVP). The plurality of system console interface control units (SCI) are connected each other in a ring fashion. Each system console interface control unit (SCI) has a processing devcice for processing an interface between the self-service processor (SVP0) and the other-information processing unit body (COM1).

An optical pickup is used to optically read recorded information on an optical information storage medium such as a compact disk in a compact disk player, for example. The optical pickup has a beam splitter having a first facet for reflecting a laser beam from a semiconductor laser toward the optical information storage medium. The right beam reflected from the optical information storage medium passes through an is diffracted by the first facet of the beam splitter. The laser beam then passes through a second facet of the beam splitter, and is then divided by a diffraction grating into a transmitted beam and a diffracted beam that is then guided through an optical waveguide. The beam splitter is simple in structure and can easily be manufactured, and hence the optical pickup is relatively small in size. Another optical pickup includes a phase layer, a polarizer layer, and a diffraction grating in a semiconductor substrate. A laser beam reflected by an optical information storage medium is caused to change the phase by the phase layer, and passes through the polarizer layer to the diffraction grating, which divides the laser beam into a transmitted beam and a diffracted beam. The phase layer and the polarizer layer are fabricated at the same time that the semiconductor substrate is manufactured.
摘要:
An optical information reading apparatus comprises an optical integration circuit type pickup in which an optical waveguide for guiding light and a condensing coupler for condensing the guided light propagating within the optical waveguide are formed on an optical integration circuit substrate, sub-couplers for radiating a part of the injected light upon the information recording surface in the vicinity of a light spot formed by the optical pickup and subsidiary light detection elements for receiving reflection light of the light radiated from the sub-couplers reflected from the information recording surface. The sub-couplers and the subsidiary light detection elements are formed integrally with the optical pickup on the optical integration circuit substrate. Thereby the detection error can be reduced, it is not necessary to use attachment parts and therefore the apparatus can be integrated to thereby make it possible to minimize the size.
