Abstract: PURPOSE:To prevent scattered matters from attaching to a wiring pattern by dividing a wiring board provided with a protective film on the wiring pattern into a plurality of pieces through laser scribe. CONSTITUTION:A wiring board provided with a protective layer is divided into a plurality of pieces through laser scribe, and the protective layer is removed from the divided wiring board. A material which can prevent matters which are scattered during laser scribe from attaching to the board and can be readily removed from the board after cutting through laser scribe is used for the protective layer. Thereby, a good wiring pattern can be acquired without attaching of the scattered matters to a fine wiring pattern on the board during laser scribe.

Abstract: PURPOSE:To improve the accuracy and to enable high speed machining by driving a reflecting mirror by a driving device translating through a translation- swing movement conversion mechanism and arranging an encorder in the driving device. CONSTITUTION:A step motor 15 is rotated at the prescribed rotating angle and this rotation is transferred to a ball screw 23 through a coupling 21, and a rod 25 is translated by the ball screw 23 at minute unit corresponding to the rotating angle of the motor. The translation of the rod 25 is converted to an angle variation of an arm 27 by a link mechanism composing of a ball pin 29 and a long groove 30 together with an axial point 31, while securing translation of the rod 25. This angle variation rotates the reflecting mirror 13, and spot of the laser beam 73 from a laser beam generator 11 can be scanned toward X-axis or Y-axis direction.

Abstract: PROBLEM TO BE SOLVED: To provide a luminous tube for a high-intensity discharge lamp which is suitable for mass production and accurate in dimension, and a method of manufacturing it. SOLUTION: First, silica powders with average particle diameter of 1 μm and 8 μm are blended (S1), then a binder and water are added to produce a clay (S1, S2). After an extrusion blow molding of the produced clay (S3) and a burning for 5 hr at a temperature of 500 deg.C (S4), the burned body is dipped in a slurry which is produced by the same blend as the silica powders of clay (S5). After the burning of the dipped burned body, a final firing is given at a maximum temperature of 1650 to 1750 deg.C.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of crack without an employment of accurate control of a sealing frit or method such as thickness increasing of capillary tube. SOLUTION: With respect to a trunk part 2 having a light emission space, a capillary tube 3 is formed by adding magnesium oxide of about twenty times and by calcining it at 1,200 deg.C, and is connected at the separatedly made trunk part 2. Thereafter, they are calcined at 1,200 deg.C and then is burned at 1,850 deg.C in hydrogen atmosphere for 3 hour, so that the average particle diameter of alumina in the trunk part 2, is 32 μm and that of the capillary tube 3 is 19 μm to increase the strength.
