    摘要: The present invention comprises a compound cavity in which a vertical-cavity surface-emitting laser and external mirror are combined, and the change in intensity of a laser beam or in mirror loss is detected by the detection unit. The detection unit includes a photodetector for directly detecting a variation in intensity of a laser beam, and PN junction potential difference detecting device for detecting a variation in mirror loss created due to a relative displacement between the external mirror and the vertical-cavity surface-emitting laser, based on a change in carrier density within the surface-emitting laser. The phase of the laser beam returning from the external mirror is determined by a relative displacement between the external mirror and the vertical-cavity surface-emitting laser, and the laser beam output varies at a period of a displacement amount corresponding to 1/2 of the wavelength of the laser beam. Such a displacement amount is calculated by the counting device and the operation device.

    摘要: An object of the present invention is to provide a three-dimensional CAD-system for adding data about a drafting direction of a die to three-dimensional data about the part to be formed by that die, and a cost calculation system for calculating the cost of the part based on that drafting direction data. A three-dimensional model generation unit of a CAD system generates: a three-dimensional shaped model of a given part based on information coming from an input operation unit. A drafting direction data setting unit establishes drafting direction data when the input operation unit is operated to designate the drafting direction of the die for press molding, injection molding or the like of the part in question. A projected area calculation unit calculates a projected area S of the part on a plane perpendicular to the drafting direction of the applicable die on the basis of the three-dimensional model of that part and the drafting direction data involved. A depth calculation unit calculates a depth D of the part in the relevant drafting direction.

The rear-mounted in-vehicle equipment can be denied access to overwriting information related to music data in the front-mounted in-vehicle equipment.

    摘要: An optical displacement sensor comprises a surface emitting laser light source, a scale and a photosensor. The surface emitting laser light source emits a light beam having a predetermined shape. The scale is displaceable in such a manner as to cross the light beam emitted from the surface emitting laser light source and has a diffraction grating of a predetermined period formed thereon for forming a diffraction interference pattern from the light beam. The photosensor receives a predetermined portion of the diffraction interference pattern. The photosensor includes light intensity detecting means comprised of a plurality of light receiving areas arranged apart from one another in a pitch direction of the diffraction interference pattern on a light receiving surface at intervals of np1 (z1 +z2)/z1 where z1 is a distance between a light-beam emitting surface of the surface emitting laser light source and a surface on which the diffraction grating is formed, z2 is a distance between the surface on which the diffraction grating is formed and the light receiving surface of the photosensor, p1 is the pitch of the diffraction grating on the scale, and n is a natural number.
