Granted: 2003-07-01
Abstract: The machine tool (5) includes a fixed worktable (11), with a given work area, two crosspieces (12) movable with respect to the table (11) along an axis (Y), independently of each other. Each crosspiece (12) bears two carriages (14) movable along an axis (X), also independently of each other, each of which is equipped with an operating head (13), movable with respect to the carriage (14) along a third axis (Z). Both the crosspieces (12) and the carriages (14) are able to position themselves in a corresponding rest position (18, 19) and move across the whole work area, so the processing can be carried out in the whole work area, even if a head (13) or a crosspiece (12) are temporarily unusable. The movements of the crosspieces (12) and of the carriages (14) are carried out by corresponding linear motors (24, 43) under the control of corresponding position indicators (27, 44). The stators (28, 29; 46, 47) of the linear motors (24, 43) are common to two motors, and the scales (37, 51) of the position indicators (27, 44) are common to two position indicators (27, 44). The shifting of each head along a third axis (Z) is operated by another linear motor (57) under the control of another position indicator (58). Both the crosspieces (12) and the heads (13) mirror each other, to enable them to position themselves at a minimum mutual distance.

Title: Laser driving method and device thereof
Inventor: INAMI TOSHIO
IPC: H01S3/09
Filed: 2003-03-13
Granted: 2004-10-11
Abstract: The invention relates to laser driving method and device thereof. In the method for oscillating laser in every period of time, due to the speed variation of irradiated object, it's not able to irradiate on equal period. Moreover, if the platform is moving and once the irradiated object stops, the laser oscillation device will be stopped by the method which uses a fixed distance and position to oscillate laser. Therefore, the heating temperature and the temperature of component irradiating laser beam accompanying with laser oscillation device will also change, so the stability of irradiation energy of laser beam will also be affected. Provide setup means 26 for the position-priority mode of oscillated signal I outputted from pulse laser 4 of moving platform in every specified period; and setup means 28 for fixed frequency mode of oscillated signal G with fixed frequency outputted from the fixed frequency pulse laser 4. When the irradiated object 5 is located at the position possibly irradiated by the pulse laser 4, connect the setup means 26 for position-priority mode to the laser oscillation device 1; when the irradiated object 5 is not at the position possibly irradiated by the pulse laser 4, connect the setup means 28 for fixed frequency mode to the laser oscillation device 1.

Title: An optical head which can provide a sub-wavelength-scale light beam
Inventor: LEE CHIH-KUNG
IPC: G11B7/135
Filed: 2003-06-26
Granted: 2006-11-11
Abstract: Diffraction limit was first proposed by Ernst Abbe in 1884, which imposed a physical limit on how small a light beam can be focused. This limit is the underlying reason that line width of photolithography, density of optical storage technology, and resolution of optical microscopy or optical sensors, etc. cannot be improved beyond a fraction of the light beam wavelength used. This application disclosed an optical head to provide a single or multiple sub-wavelength light beams, which can be used in area such as photolithography, optical storage, optical microscopy, to name a few. The newly disclosed design includes a transparent substrate, a thin film, and a surface structure with sub-wavelength surface profile. The incident light transmits through the transparent substrate, forms a surface plasma wave along the sub-wavelength aperture located within the thin film, and finally re-emits through spatial coupling with the sub-wavelength profile of the surface structure. As the coupled re-emitting light beam or light beams can maintain the waist less than that of the diffraction limit for a few micrometers out of the surface with sub-wavelength profile in many cases, this invention can have applications ranging from micro or nano manufacturing, metrology, and manipulation by using light beams with waist smaller than the diffraction limit.
