Title: Manufacture of welding shape steel
IPC: B23K9/127
Filed: 1992-03-13
Abstract: PURPOSE:To protect a non contacting sensor from spatter, arc heat and the like when welding is carried out and a welding head is always highly accurately guided to the welding part of a material to be welded by parting the non contacting sensor from the material to be welded. CONSTITUTION:Welding torches 30R and 30L are provided on a driving box 20 moving in a breadthwise direction of a steel plate for web S1 on portal travelling vehicle 10 by moving gears 21R and 21L in a freely vertically movable state by elevating/lowering gears 32R and 32L. Non contacting sensors 40R and 40L are provided on the driving box 20, in a same manner, in a freely vertically movable state by elevating/lowering gears 43R and 43L. After the welding torches 30R and 30L are positioned for the steel plate for web S1 and steel plates for flange SR and SL, the non contacting sensors 40R and 40L are parted from the steel plate for web S1 and steel plates for flange SR and SL. Since the non contacting sensors 40R and 40L are at their retreating positions when the welding is carried out, the contamination or breaking of the non contacting sensors 40R and 40L are not generated and the positions of the welding torches 30R and 30L are highly accurately detected and controlled for a long period.

Title: Receiving device
Inventor: KURATA HIROTAKA
IPC: H04B1/30
Filed: 1978-07-25
Abstract: PURPOSE:To prevent occurrence of the beat sound when the channels are selected. CONSTITUTION:DC component detection circuit 18 is provided to output TP2 of multiplication detector 10. On the other hand, switches S1a and S1b are provided on the way to the audio output circuit. These switches are controlled with the output of circuit 18 so that beat eliminating filters 19 and 20 can be connected by insertion on the way to the output circuit through operation of S1a and S1b. The DC component is contained in the output of multiplication detector 10 in the state under which the phase synchronous circuit is locked, and this output switches S1a and S1b. As a result, the audio output of phase comparator 6 and detector 10 are separated into the right and left channels through dematrix circuit 13 to be applied to speakers 16 and 17. With the phase synchronous circuit unlocked, no DC component emerges to the output of detector 10 and switches S1a and S1b are switched toward contact 1. Thus filters 19 and 20 are connected by insertion.

Filed: 1991-04-22
Abstract: PURPOSE: To obtain a method for bringing all print images to accurate positions by entirely inclining a sheet again straightly after passing printing units or a value obtained from an inclined position of the shet and an angular deviation of the print image of next printing unit. CONSTITUTION: In the case of adjusting a printing machine having four printing units, a sheet B is straightly supplied at the first unit. At a point I, the sheet occupies an inclined position, which is needed to correct an amount of a distance 2X. Thus, a sheet conveying drum 4 is moved upward at an amount of a distance (x). At point II, it must be corrected by a valu of the distance 2y to a reverse side, and hence an additional correction of the distance (y) is superposed, and the drum 4 is adjusted by total amount (z). At point III, i.e., at the third unit, the sheet is not adjusted to be inclined. Accordingly, the drum 4 is moved above by the distance (y). Thus, an online correction is executed.

Abstract: PURPOSE: To accelerate the sedimentation of solids as well as discharge separated solids and liquid with good efficiency by subjecting a solid-liquid mixed slurry to the vibrating dehydration in a tank equipped with a vibrator, having a drain port in its upper side and a discharge port in its lower or bottom side.  
     CONSTITUTION: The mixed slurry of a high specific gravity and a wide particle distribution is put in the tank 1 and then the vibrating motor 2 is actuated to vibrate the tank 1 to settle the solids present. Then, after discharging the liquid on the solid layer through the drain port 7 by opening a valve 8, a vibration is again applied to the tank, whereupon fine particles penetrate into among solid particles to cause the solid layer to closely packed, liquid content among coarser particles to sweat to the upper part on the solid layer, and enriched slurry containing fine particles to remain due to the wave motion of the liquid content. Again, a valve 8 is opened to discharge the enriched slurry with the aid of vibration as needed, and then a valve 4 is opened to discharge a dehydrated cake by means of vibration. Thus, the dehydration of slurry can be effectively performed by utilizing vibration in this way.

Abstract: PURPOSE:To thicken and thin a decorative material with a pattern corresponding to an uneven figure, by a method wherein simultaneously with figuring of an uneven form figure on the surface of a molding of a pottery basis material body by pressing a transfer mold on the surface of this powdery body is transferred for firing with the pattern corresponding to the uneven figure. CONSTITUTION:A transfer mold 22 on the surface of which a powdery body of a decorative material such as a pigment or glaze are stuck is pressed on the surface of a molding 20 of a pottery basis material body, simultaneously with performing of an uneven form figure on the surface of the molding 20 the powdery body is trans ferred with a pattern corresponding to the uneven figure and then fired. In other words, since pressing force on a protrusion of the transfer mold 22 becomes higher as compared with that of a hollow part when the transfer mold 22 is pressed on the surface of the basis material molding 20, the powdery body of the decorative material stuck to the protrusion is transferred to the surface of the basis material molding 20 in more large quantities and thicker. With this construction, thickness and thinness in the decorative material of the pattern corresponding to the uneven figure is generat ed on the surface of the molding 20 and the beautiful figure and decoration are obtained.
