Camera calibration which is robust against noise factors such as variation in environmental lighting and obstructions is realized. Light-emitting markers, whose on/off states can be controlled, are arrayed in a matrix on a reference panel on which an object is placed. The light-emitting markers blink in accordance with respective switching patterns in synchronism with the frame of continuous imaging of a camera. A three-dimensional measuring instrument determines the time-varying bright-and-dark pattern of a blinking point from the image of each frame and identifies, on the basis of the pattern, to which light-emitting marker each point corresponds. By reference to the identification results, camera calibration is performed, and a coordinate transformation parameter is computed.

An object is to provide a light source unit that focuses a laser beam, having different divergence angles in longitudinal direction and lateral direction, so as not to allow longitudinally and laterally deviating from an incident end-face of an optical fiber. The light source unit herein provided is configured to form the laser beam 9 emitted from a laser element 7, having different divergence angles in longitudinal direction and lateral direction, into a parallel-ray laser beam by collimating laser beam rays in a plane in which the beam has a larger divergence angle using cylindrical lenses 10 and 11 in a first lens barrel 1 and also by collimating laser beam rays in a plane in which the beam has a smaller divergence angle using a cylindrical lens 12 therein, and to focus the parallel-ray laser beam onto the entrance of the optical fiber 3 using circular lenses 13 and 14 in a second lens barrel 2, whereby the first lens barrel 1 and the second lens barrel 2 are regularly positioned and directly coupled so that their optical axes coincide with each other.

A display device for projecting images of an imaging plate into a retina of an eye of a viewer has a light source, a scattering plate for scattering the light from the light source, an imaging plate transmitting the light scattered by the scattering plate, and an optical unit with a lens for focusing the light transmitted through the imaging plate into an eye of the viewer. The scattering plate can move between the light source and the imaging plate.

A process for making a polycrystalline silicon film includes forming, on a glass substrate, an amorphous silicon film having a first region and a second region that contacts the first region, forming a first polycrystalline portion by irradiating the first region of the amorphous silicon film with laser light having a wavelength not less than 390 nm and not more than 640 nm and forming a second polycrystalline portion that contacts the first polycrystalline portion by irradiating the second region and the portion of the region of the first polycrystalline portion that contacts the second region of the amorphous silicon film with the laser light.
摘要:
Into a raceway groove formed between outer and inner races, there are incorporated a plurality of rolling elements of which outside diameters serving as the rolling contact surfaces thereof each has a curvature in the axial direction as well and also each of which has a radius smaller than the radius of the raceway surfaces of the outer and inner races. The rolling elements are arranged in such a manner that the mutually adjoining rolling elements cross each other alternately and also that the outside diameters of the respective rolling elements are always contacted at two points with the raceway surfaces of one race and the raceway surfaces of the other race.

A telephone apparatus is disclosed which includes a communication circuit (10) including a microphone (15) and a speaker (14) for providing communication between an operator and a network and outputting sound data from the sound receiving unit and the network; a memory card receiving unit (13); a memory card detector (13a); a memory (4) for storing the sound data; a control circuit (2) responsive to the memory card detector and a recording command for storing the sound data in the memory and reading the sound data from the memory only when the memory card is received by the memory card receiving unit. The memory card stores an ID code and the control circuit registers the identification code on recording. When playing is commanded the control circuit inhibits Playing when the ID from the memory card disagrees with any of registered ID codes. When there is no space in the memory, the control circuit writes the sound data over the sound data only when the ID code from the memory card agrees with one of the registered ID codes. The telephone apparatus further includes a serial interface (23) for storing the sound data in the memory in the memory card.
