Title: Light focus spot coaxiality measuring device
Inventor: OKAWA KATSUHISA
IPC: G01B11/00
Filed: 1992-04-22
Abstract: PURPOSE:To accurately measure the outer diameter of a cylinder shape work and the coaxiality of the light focus spot for the light emitted from the cylinder shape work. CONSTITUTION:The object lens 21 attached to a microscope 8 is to have high magnification and high NA, and by observing the light focus spot of a cylinder shape work 17 with high magnification, the position of the light focus spot is accurately detected. The displacement of the X-Y stage 2 for sight field movement which is required because of narrowing of the sight field of the microscope 8 due to the high magnification is read with a high accuracy scale placed at the same elevation as the upper surface of the cylinder shape work 17 and the interference between the axes is corrected so that more than three points on the outer diameter of the cylinder shape work 17 are accurately measured by moving the X-Y stage 2. A controller (a) 16 calculates the coaxiality of the outer diameter of the light focus spot from the position of the light focus spot and the position on the outer diameter of the cylinder shape work 17.

Filed: 1990-04-17
Abstract: PURPOSE:To improve working efficiency by continuing the work with safety control separating a torch by the prescribed distance from a base material at the time of detecting powering of voltage at between the base material and the torch and detecting the generation of double arcs. CONSTITUTION:At the time of inputting the deviation signal between the aimed stand-off signal calculated in the aimed stand-off signal computing element 9 and the actual stand-off signal to the stand-off correcting signal generator 15, the stand-off correcting signal, by which the deviation signal becomes zero, is outputted to a robot driving control signal generator 13. At the same time, the cutting velocity is controlled so as to become the aimed cutting velocity. When the double arcs generate, nozzle voltage is lowered to near zero volt and at the time of lowering to lower than the set voltage, the double arc signal from a double arc deciding instrument 14, is inputted to the computing element 9 and a control signal generator 13, and the aimed stand-off signal is corrected to the value, at which the double arc disappears. In the control signal generator 13, the cutting velocity is controlled so as to lower this by lowered current density of plasma arc with the correction.

IPC: H04B10/00
Filed: 1984-05-23
Abstract: PURPOSE:To obtain the same effect as the arrangement of the length of optical fibers from a star coupler to each communication equipment by giving a prescribed waiting time from a point of time detecting the end of signal transmission of other station to a point of time when the signal transmission of the own station is started. CONSTITUTION:After a transmission data is stored once in a transmission buffer 31, a transmission request signal is transmitted to a transmission control circuit 30. The circuit 30 starts transmission when both transmission waiting control signals 19, 37 are logical ''0'', and after a prescribed length of redundancy bit is generated from a redundancy bit generator 18, a transmission data is changed into an optical signal at a transmitter 2 from the buffer 31 and transmitted to the other communication station via an optical fiber 5a and the star coupler 4. When an output exists in a reception detecting circuit 27 within a time set by a timer circuit 25, the circuit 30 stops immediately the transmission. When the other station finishes the transmission and after an output signal 37 of the circuit 27 is logical ''0'', the result is delayed at a delay circuit 29 by a delay time TD so as to await the transmission of the own station. When the signal 37 reaches logical ''0'' after the time TD, the circuit 30 starts the transmissioi succeedingly. The time TD is decided depending on the distance from the coupler 4.
