A ratio of a length of resin flow-in to a radius of an optical component is not larger than 0.25, and gas is blown directly against a laser irradiated part radially and diagonally downward from an upside position corresponding to a center of the optical component. A laser line beam having longer sides extending in a direction along an inner wall is cast by a laser radiation device while being moved in the direction of the longer sides.

A plasma display (PDP) manufacturing method and display panel includes a display electrode forming step of forming a plurality of pairs of display electrodes in parallel lines on a main surface of a first plate, and a plate sealing step of aligning the main surface of the first plate with a main surface of a second plate, and sealing the first and second plates together. The display electrodes are formed by coating the main surface of the first plate with display electrode material, and performing laser ablation on parts of the display electrode material, while the remaining parts of the display electrode material form the display electrodes.

A machine tool of small scale, light weight, and low cost, yet accomplishing a high degree of precision in machining. A spindle (,) is encased in a body frame (,) and disposed preferably in such a manner that the spindle (,) is movable along an axial center thereof or Z-axis direction by means of a Z-axis moving means (,). Either Y-axis table (,) or an X-axis table (,), at least being capable of moving along X-axis or Y-axis direction, or both is provided at one end of the spindle (,) on one side of the body frame (,) and arranged to be vertical with respect to the axial center of the spindle (,).

A rectilinear motion apparatus includes two shafts arranged in parallel, a driving motor and a driving pulley coupled to one of the two shafts, an idler pulley coupled to the other of the two shafts, an endless toothed belt arranged between the driving pulley and idler pulley, and a slider disposed between the driving pulley and the idler pulley. The slider includes a first moving pulley and a second moving pulley of a diameter larger than a diameter of the first moving pulley. The first and second moving pulleys are integrally fixed to one another for rotation about the same axis so as to rotate simultaneously. A first pair of guide rollers are disposed on the slider adjacent the first moving pulley to guide a lower run of the toothed belt, and a second pair of guide rollers are disposed on the slider adjacent the second moving pulley to guide an upper run of the toothed belt. Regulating devices are provided for regulating shifting of the toothed belt in a disengaging direction of the toothed belt away from the first and second moving pulleys. Each regulating device is arranged on the slider and in a vicinity of an engaging part where the toothed belt is meshed with one of the first and second moving pulleys.
