摘要： PURPOSE:To provide a semiconductor-laser excited solid laser device, in which oscillation efficiency is further made better than conventional devices. CONSTITUTION:In a semiconductor-laser excited solid laser device, a solid laser rod 4 is excited by projecting semiconductor laser beams 2 to said rod 4 and the output beams 9 of laser oscillation are acquired. The laser uses a elliptic mirror 11, in which the radius of curvature in the direction perpendicular to the joint surface 12 of a semiconductor laser 1 is different from that in the direction parallel to the joint surface 12, and the ratio of the former to the latter is equal to the ratio of a spreading angle in the vertical direction to one in the horizontal direction. The mirror has an elliptical cross section perpendicular to an optical axis.

摘要： PURPOSE:To enable easy reregulation of a burner into an ideal combustion state by a method wherein when the burner is previously in a given combustion state, a ratio of the area of a given section to the area of all sections is determined, and an air flow rate, a fuel flow rate, and a recirculating gas amount are controlled so as to maintain the same ratio during operation. CONSTITUTION:Temperatures at points at the side of flame obtained by measurement are divided at intervals of a proper temperature step, for example, 10 deg.C to prepare a constant temperature line distribution diagram ranging from 1500 deg.C to 1200 deg.C. The area of each temperature section is determined, the areas are S1, S2, S3, and S4. In the case S0=S1+S2+S3+S4, regards a ratio between R1=S1/S0 and R2=(S1+S2)/S0, a value in the combustion state of each burner in a normal combustion state is previously experimentally determined. An air flow rate control damper 11, a primary air flow rate regulating damper 13, and a secondary air flow rate regulating damper 14, and a fuel injection valve 08, a recirculating gas flow rate control damper 10, and a burner recirculating gas regulating damper 12 are operated so that R1 and R2 are adjusted to respective values. The combustion state of each burner can be easily maintained in an excellent state.

摘要： PURPOSE:To allow cutting of even a thick work with a single laser oscillator by providing a half mirror disposed in a laser light path and condenser lenses which are respectively disposed in the transmitted light path therefrom and a reflected light path. CONSTITUTION:The laser light outputted from the laser oscillator 21 is reflected by the half mirror 22 and is focused via the condenser lens 23 disposed in the reflected light path thereof to the focus of the lens matched on the work 24. Further, the laser light outputted from the laser oscillator 21 is reflected by the mirror 25 disposed in the transmitted light path of the half mirror 22 and is focused via the condenser lens 26 disposed in the reflected light path thereof to the focus thereof matched in the work 24. The work 24 can be cut by moving the work 24 in such a manner. The laser light is, therefore, focused to the different positions of the thick work by the condenser lenses of different focal distance. The cutting of even steel tires which are usually difficult to cut is consequently possible.

摘要： PURPOSE:To accurately detect the presence and position of an internal defect such as the flaw and separation of the internal thickness part or surface coating film of a cylindrical body by making a linear scan by an infrared camera in parallel to an axis and detecting the internal defect of the body to be tested from the abnormality of a display temperature distribution. CONSTITUTION:The body 1 to be tested is rotated by tested body rotatinonal motor 9 as shown by an arrow at the intervals of constant angle synchronously with the horizontal synchronizing signal 10 of the infrared camera 7 and the angle of its rotation is set and controlled by a motor controller 12 so that the body to be tested makes one turn in the one-image-plane display time of a monitor television 8. Camera scanning lines in a camera observation direction 17 therefore displayed as the display scanning lines 20 of respective image plane positions 19 on the monitor image plane 18 and the temperature distribution of the whole periphery of the body 1 to be tested is developed and displayed in one image plane 18 of the monitor television 8. Displayed temperature has a difference from the periphery at the point and the presence and position of the defect are detected.

摘要： PURPOSE:To make it possible to measure the concn. distribution or particle temp. distribution of particles distributed in a floating field in a non-uniform state, by taking-in intensity information of transmitted beam obtained by irradiating the floating field of particles with laser beam other than the intensity information of two-wavelength beam emitted from particles. CONSTITUTION:A part of Ar laser beam 27 emitted to the outside of a furnace passes through a laser beam selecting half mirror 29 and a lens 30 and beam intensity Ilambdaa is detected by a monochrometer 31 with a wavelength lambdaa, a detector 32 and a potentiometer 33. Next, an Ar laser transmitter 24 and the half mirror 29 are parallelly moved by DELTAgamma to a gamma-direction and the transmission intensity Ilambdaa of laser beam 27 is measured in the same way to calculate radiation intensity Fj which is, in turn, stored in the memory of a calculator 37. Next, by repeating this operation, Fj distribution in a theta0-direction is calculated. Subsequently, a pair of the Ar laser transmitter 24 and the half mirror 29 are rotated by DELTAtheta to a theta-direction and the above-mentioned operation is repeated to calculate Fi in all directions. These data are subjected to operational processing by the calculator 37 to make it possible to calculate the temp. distribution of particles.
