The light emission mode of the soln. changes as shown in (a)-(g) by the wavelength of measuring light when the instrument is irradiated with the measuring light from one direction. The easy measurement of the wavelength of the near UV rays is, therefore, possible, by utilizing the change in the light emission mode of the soln. in the vessel by the wavelength of the irradiating light. The setting of the wavelength at which the light is emitted over the entire area of the vessel is possible by changing the concn. of the soln. Further, the org. metal complex compd. may be incorporated into the transparent resin which allows the transmission of the near UV rays.

IPC: B23K9/095
Filed: 1987-08-10
Abstract: PURPOSE:To enable welding by high-quality straight beads by changing the progression speed of a welding torch in such a manner that the speed is lower as the mutual gap between materials to be welded is wider and is higher as the gap is narrower in accordance with the data on said gap. CONSTITUTION:Teaching (programming) of a computer is executed by operating a remote operation board. The mutual gap G2 of the 1st and 2nd materials W1, W2 to be welded near the end point of welding is determined and the change in the mutual gap is computed by this gap and the mutual gap G1 near the start point of welding. Welding is then executed by the straight beads from the start point P2 of welding toward the end point P3 of welding while the progression speed of the welding torch is changed so as to decrease the speed with an increase in the size of the mutual gap and to increase the speed with a decrease in the size of said gap on the basis of the welding speed assigned by the welding conditions. The welding speed is changed according to the nonuniformity of the mutual gap in such a manner, by which the mutual gap is filled at a uniform height and high-quality automatic welding is executed.

Abstract: PURPOSE:To prevent air-fuel mixture from becoming too rich, by prohibiting asynchronous injection of fuel when the engine speed is not within a prescribed range in an internal combustion engine in which lack of fuel at the time of accelerating the engine is supplemented by effecting fuel injection asynchronously with roatation of the crank shaft. CONSTITUTION:In operation of an engine, a fuel injection control circuit 19 at first detects a datum injection quantity of fuel from the output signals of an air- flow meter 3 and a crank angle sensor 14, and then the datum injection quantity is corrected appropriately on the basis of the output signals of a water- temperature sensor 15, and an O2-sensor 16, etc. According to the corrected injection quantity, an injector 8 is opened in synchronism with rotation of the crank angle. At the time when acceleration oaf engine is detected, on the other hand, the injector 8 is made to cause asynchronous injection of fuel so as to supplement lack of fuel supplied by the above synchronous injection. However, when the engine speed is not within a prescribed range, the above synchronous injection of fuel is inhibited so as to prevent the air-fuel ratio from becoming too rich.
