摘要： PROBLEM TO BE SOLVED: To provide a method and a device which achieve both of high cracking speed and high cracking position precision without generating thermal damage on a workpiece by the heating of a material in high quality thermal stress cracking for a brittle material which does not generate cullets and microcracks which have been inevitable in the conventional mechanical scribing method. SOLUTION: In a region wide as much as possible on a workpiece, a non-uniform heating temperature distribution of relatively low temperature which is slowly distributed is provided so as to reduce heating temperature for generating stress, and the thermal damage of the workpiece is prevented. Besides, heating energy concentrated on a relatively micro region as a cracking position decision factor is superimposed on the heating temperature distribution, also, the position is off-set, or negative feedback control is performed, and further, if required, positive feedback control is performed so as to improve cracking position precision. As the heating laser, a CO 2 laser, an Er:YAG laser capable of achieving full-cuts or an Fe +2 :ZnSe laser capable of selectively achieving full-cuts and extremely deep scribes at various sheet thicknesses is used.

摘要： A solid-state laser oscillating device which is inexpensive and capable of obtaining a high power. A plurality of laser crystals (YAG laser crystals, etc.) (1a, 1b, 1c) are arranged along the optical axis of an optical resonator so as to maintain optical contact with one another. Adjacent ones of the laser crystals have surfaces facing each other with an adhesive layer (10, 20) interposed therebetween, to form an array in a straight-line as a whole. An adhesive having a low light absorbance with respect to a laser beam of oscillation wavelength or an excitation light is used for forming the adhesive layers (10, 20). If the refractive index of the adhesive is substantially equal to that of the laser crystals, optical matching is achieved. The adhesive layers (10, 20) may be replaced by some other transparent material. The adjacent laser crystals may be arranged with a narrow gap therebetween or held in surface contact with each other.

摘要： A turbo blower for a laser device, including a shaft having an impeller on one end thereof, a pair of bearings, having inside grease spaces and supporting the shaft Non-contact seal portions are provided for preventing an outflow of grease, whereby other spaces for retaining the grease are formed on either side of the bearings. Although the grease in the inside spaces of the bearings is urged to escape from the bearings by the centrifugal force of the rotation of the shaft, the grease is prevented from flowing out of the spaces on either side of the bearing by the non-contact seal portions.

摘要： This invention enables the full-body (throughout the entire thickness) scribing of a plate made of fragile material such as glass by irradiating the work with the laser beam for heating with or without cooling and thereby generating the tensile thermal stress in the work which exceeds the cleavage toughness of the material, dispensing with the mechanical breaking. In this invention, the absorption of the beam in the work is so controlled that the beam, while being absorbed in it, is either transmitted through it or reaches the adequate thickness of the work and the entire thickness scribing is realized. This absorption control is done by selecting the laser beam wavelength so as to achieve the proper absorption in the absorption spectra of the material either due to the electronic transition or the lattice vibration. The doping of the material, in which the commercially available high power laser beam can be absorbed properly and either of the absorption or emission in the visible light spectral range does not exist, can also be utilized for this absorption control. In this case, the quenching of the fluorescence which may arise after the beam absorption is useful. This invention enables the profile scribing of work or the selective scribing of piled work consisting of plural number of plates.

摘要： A piercing method using a laser, in which the processing time is made shorter; a thermal runaway is prevented; and dispersion of the processing time is made smaller. According to this method, piercing operation is started with an initial pulse frequency P.sub.0 and an initial pulse duty ratio Q.sub.0, and the pulse frequency and the pulse duty ratio are increased by increments P and Q, respectively, with every passage of a predetermined time T. The pulse frequency and the pulse duty ratio are increased by stages. After this increase is repeated a predetermined number of times, or after the passage of a predetermined time from the start of processing, processing is continued to the end maintaining the increased values. This piercing method enables the processing time to be reduced to 1/3 to 1/5, as compared with the conventional method. In addition, this method prevents a thermal runaway, and reduces the dispersion of the processing time.

The electrode units include electrodes and dielectric layers, respectively, and each of the electrodes is formed by depositing silver as an electric conductor on the outside periphery of the tube wall by metalizing. The dielectric layers are formed to cover the electrodes, respectively, and are disposed on the outside periphery of the tube wall by depositing a dielectric material such as a ceramic material, glass, resin or the like by spray coating, coating, baking or the like or by bonding independently formed dielectric materials to the electrodes. The dielectric layers have a thickness of about 0.1 mm-5 mm.

摘要： A laser beam machining method for cutting a workpiece in accordance with a machining program composed of a succession of move commands and laser output commands. An angle of a machining path is calculated on the basis of a move command under execution and a subsequent read out move command (S2, S3). The angle of the machining path is compared with a preset angle (S4), and when the angle of the machining path is more acute than the preset angle, the movement for machining based on the move command under execution is decelerated and stopped (S5). In this case, the laser output command is changed from a cutting condition to a piercing condition, to carry out a piercing operation, and when the piercing operation is completed, the movement for machining is restarted in accordance with the subsequent move command. When the movement for machining is restarted, the laser output command is changed from the piercing condition to the cutting condition in accordance with the movement for machining. Accordingly, a clean-cut acute-angle portion can be obtained by this machining.

摘要： A turbo blower is used in combination with a gas laser oscillation device for machining, e.g., cutting off, workpieces. The turbo blower comprises a shaft (2) having an impeller (1) on one end thereof, a pair of bearings (5, 6) on which the shaft (2) is supported, and a motor (3, 4) for rotating the shaft. Heat radiating fins (11) are mounted on the shaft (2) for radiating the heat which is generated by a rotor (3) of the motor, thus preventing the heat from being transmitted to the bearings (5, 6). The heat radiating fins are forcibly cooled by a portion of a laser gas for thereby greatly increasing the heat radiation efficiency. The service life of the grease in the bearings and the bearings themselves is increased, thus reducing an expenditure of labor for grease replenishment and bearing replacement. The bearings are also increased in reliability.
