摘要： PURPOSE:To measure the degree of packing in a mold nondestructively by pressing and placing positive and negative electrode terminals on the surface of facing sand after the manufacture of the mold and measuring the electric resistance value of the facing sand. CONSTITUTION:The pattern surface of a mold is formed of facing sand 3 prepd. by mulling beforehand a suitable amt. of powder consisting of a conductive material. Positive and negative electrode terminals 6 are pressed at constant intervals on the surface of the facing sand 3 of the mold after hardening. If electricity is conducted thereto with a measuring device 8, electric current flows in the surface or in the inside of the facing sand between the terminals 6, and the electric resistance value corresponding to said parts is indicated by the deflection of the meter of the device 8. When the degree of packing increases in the case of the mold, the electric resistance value decreases and when said degree decreases, the electric resistance value increases and therefore, it is possible to measure the degree packing by measuring the electric resistance value.

摘要： PURPOSE:To enable installation of a conveyor even with sharp grade and in the flowing water by means of preventing conveyed objects from falling off in such a way that bulkheads are provided on a belt at the determined intervals, and both sides of the belt are reshaped along both sides of the bulkheads on the way to conveye them. CONSTITUTION:A belt 1 made of rubber, plastic or steel provides bulkheads 2 which are shorter than the width of the belt in their length at their determined intervals, and arcuate at their both ends. And when the conveyed objects are loaded and delivered, the belt 1 is flatly maintained, and the belt 1 is gradually reshaped starting at their end parts on the way to convey them so that the belt 1 is brought to come alongside the side lines of the bulkheads. In consequence, when the belt 1 is to be flattened, a horizontal roll 4 is arranged under the belt 1, and when the belt 1 is reshaped, a tilting roll 5 is arranged on the both sides of the belt 1. Thus, the conveyed objects can be not alone simplified in their loading and delivery, but also prevented from falling off.

摘要： PURPOSE:To enable the easy manufacture of a smooth circumferential joint by directing the frame, which is mounted with one pressure roll in precedence to a welding torch and each one on the right and left and the torch, to the weld line direction by a rotation-driving means. CONSTITUTION:Three rolls 5, 6, 6 are provided on the bottom surface of the frame 19 suspended to a pipe making device frame 18 by way of a hydraulic cylinder 10, rotary frame 11 and support rod 29, and a welding torch 7 is fixed on the centerline of the triangular spacing formed by said rolls 5, 6, 6. When a steel strip 2' being coiled in the state having camber comes, oil pressure is exerted to the top of the rod of the cylinder 10 to lower the frame 19 and let the rolls 5, 6, 6 contact the steel plate 2'. Further, oil pressure is applied to hydraulic cylinders 29, 23, 23 to press the rolls 5, 6, 6 onto the steel plate 2' to eliminate camber and allow the steel plate make sufficiently close contact with the underlayer, after which welding is started, whereby the steel plate 2' being subsequently coiled in spiral form is continuously automatically welded.

摘要： PURPOSE:A cylinder made of elastic film, with its both ends sealed with covers, is filled with powder so that it is shaped into a barrel form. By applying pressure to the above-described film in its radial direction and to the covers in their axial direction, a cylindrical powder molding free from any constriction can be produced. CONSTITUTION:Elastic film 1 is inserted into cylinder 5 fitted with seal plate 2b, ring 3b and stopper cover 4b only on its lower end. Ring-shaped stopper 8b is inserted into the end part of cylinder 5 to support it. Then the cylinder is filled with powder 10 through the opening. This operation is continued until the elastic film expands so as to assume a barrel form in contact with the inner wall of barrel- shaped cylinder 5. After this, the open end of elastic film is covered in a similar manner. After inserting ring-shaped stopper 8a, the entire body is placed into the pressure tank, and static pressure is applied, by means of a flowing body, from the axial and radial directions of cylinder 5 so that elastic film 1 assumes gradually a cylindrical form, and thereby the desired powder molding is obtained.

摘要： PURPOSE:To make a single crystal unidirectional solidifying material having large diameter and long length without convection current to stable and good quality and to reduce the production cost, by adding a static magnetic field on an interface of the solidifying phase in the unidirectional forced-cooling solidification of molten raw material in a solidifying vessel. CONSTITUTION:The molten metal 1 in the solidifying vessel consisting of a refractory 3 is uniformly cooled from the bottom part by a cooling Cu box 9 and resistance wires 5 for circumferential heating, to make the unidirectional solidifying material 2. Then, by adding the static magnetic field caused by the unidirectional DC coil 7 at the circumference, the convection current at the interface is prevented and the large diameter and long single crystal unidirectional solidification is made to stable state. Therefore, the unidirectional solidification is stably generated, and the quality is become to good and production cost is reduced.

摘要： PURPOSE:To raise the efficiency of dredging work by providing a fixed wheel fixed to the fixing shaft at the tip of a ladder, having a sludge discharge hole, side plates to insert the fixed wheel, plural blades fixed between the side plates at a fixed pitch, and a rotary drive means. CONSTITUTION:The ladder 2 of a dredger (not illustrated), a fixing shaft 17, and a fixed wheel 16 are mutually fixed, and an oil-pressure motor shaft 18, side plates 12, and blades 13 are fixed rotatably by an oil-pressure motor 14. When the side plates 12 are turned in the direction of arrow, soil and sand are excavated by the lower blade 13 in contact with the soil of the seabed and continuously scooped up to the space formed by the side plates 12 and the wheel 16. Since the left-handed lower part of the wheel 16 is connected to the sludge discharge port 15, soil and sand are mixed with the sea water and discharged through a sludge discharge tube 3. Since the bucket wheel has no corners to be adhered with soil and sand and the direction of discharging soil is matched with the flow of the sea water, even cohesive soil can easily be transported with the flow of the sea water.
