Abstract: PURPOSE: To prevent spark production between electrode plates and studs by so forming the stud through-holes to be drilled in the electrode plates that the longitudinal diameter becomes larger than the transverse diameter.  
     CONSTITUTION: In the two-stage type electric dust collector, the through-holes for the studs 3 connecting a dust collecting electrode 1 or the studs 5 connecting a charging high voltage electrode 2 to conduct the high voltage electrode or dust collecting electrode respectively are so drilled that they form a oval or polygonal shape of a larger longitudinal diameter than a transverse diameter. More specifically, the transverse diameter is so determined that the spacing between the electrode  plate and stud maintains the specified insulation distance, as against which the  longitudinal diameter is determined at such a ratio that it becomes 1.5 times in the  case of the oval shape and 1.8 times in the case of the polygonal shape. The fluid  smoke dust deposting on such electrode plates and flowing down the same goes to  the circumferential edges owing to water draining action at the top edges IHU of  the through-holes and even if it drops onto the studs, there is no possibility of  sparking.

Abstract: PURPOSE:To facilitate crystal growth on a substrate in one process by a method wherein a groove, which has a pigeon-tail-shaped cross section and extends in a stripe shape, is formed in the substrate and current-constricting layers are formed only on the parts of the substrate surface outside the groove by utilizing a surface tension of a growth solution for the current-constricting layer. CONSTITUTION:An etching mask is applied on a substrate surface 10a and a stripe shape window is formed in the mask and a groove 11 is formed in the substrate 10 by etching through the window. The cross section of the groove 1 taken perpendicular to the stripe direction has a pigeon tail shape. Then current-constricting layers 12 are formed by liquid phase epitaxial growth of N-type InP layers. In this process, the N-type InP growth solution 12a does not penetrate into the groove 11 and does not wet the inside of the groove 11. Therefore, the current-constricting layers 12 grow only on the parts of the substrate surface 10a outside the groove 11. Then buffer layers 13 are formed on the current-constricting layers 12 and inside the groove 11 and, successively, the first cladding layer 14, an activation layer 15, the second cladding layer 16 and a cap layer 17 are formed on them to obtain a wafer composition with the crescent activation layer 15.

The clay in the half-kneaded state is then discharged forcibly from a clay discharge port 13. A stylus sensor 13' detects the required amt. of the forcibly discharged clay. Hot air is at the same time blown from a port 18 for injecting the hot air for accelerating solidification. The force is exerted to the sensor 13' when the sensor arrives at the point to cut away. The spindle 10 is then turned over by the device 17 and the clay 3 is again cut away by the ball cutter 12.
