Title: Production of combined material by welding lining granular body onto base material
Inventor: KUROKI TAKANORI
IPC: C23C24/08
Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To rapidly heat a granular body in the method for producing a combined metallic material such as a wear-resistant liner by generating an electromagnetically induced current in the metallic granular body placed on a base material to heat the granular body and welding the granular body onto the base material. SOLUTION: A part of a granular body is transformed into the flaky, wiry, bent, looped or coiled small piece long in one direction to make the induced current easy to flow. Consequently, the granular body is rapidly heated by a high-frequency induction coil, and a dense lining layer is formed with high efficiency. This method can be applied to any substance capable of being heated by an electromagnetically induced current. Since the cooling rate is increased, quenching is conducted simultaneously with the shaping, and a high-hardness lining layer is easily obtained. Further, turnings, chips, scraps, etc., are effectively utilized, and a relatively inexpensive product is obtained.

Abstract: PURPOSE:To distinguish an ultrasonic test (UT) signal and a noise signal easily and positively by determining the positions, of a signal from a part to be tested obtained by a probe, in the moving direction of said probe and in the rotating direction on two-dimensional coordinates. CONSTITUTION:As a probe 8 is moved while rotating in a boiler tube 1 to pass through a part 15 to be tested of a welding part 4, signals S are obtained from detecting parts (a), (b) and transmitted to an ultrasonic flaw detector 9. For example, the number of signals S within an area A is set beforehand in a personal computer 13. The signal S sent from the detector 9 is analyzed by the personal computer 13 thereby to obtain the position of the signal on the XY coordinates and at the same time, the number of the signals S in the area A is calculated. By comparing the calculated number (n) with a set number (n'), the signal S is determined to be a noise signal N if n<n', whereas the signal S is judged to be a UT signal U if n>=n'. In the case where the signal S is determined to be a UT signal, the signal S is indicated by a CRT 14 along with the position (coordinates XY) thereof. Accordingly, the UT signal and noise signal can be easily distinguished from each other positively.

Filed: 1982-12-17
Abstract: PURPOSE:To elevate measuring accuracy by providing two optical sensors at a specified interval along the running direction of a filamentous body to output a pair of pulse detection signals positive and negative in the direction each time marks pass. CONSTITUTION:A fishing line 2 is fitted with optically detectable marks 2a as formed by applying a white paint larger in the reflectance than the surface of the body by a specified length (l) at a fixed interval and a measuring device 1 is provided with a sensor head 3 to optically detect these optical marks 2a passing.

Since a fluctuation component won't appear as output voltage Vc as inputted into a differential amplifier as identical phase component even when the levels of the detection voltage Va and Vb fluctuate with the vibration of the line in a guide hole 4a. Thus, the signal-to-noise ratio of the detection signal can be elevated.

Filed: 1983-11-21
Abstract: PURPOSE:To prevent shifting and sand loss of sand molds and to transfer the sand molds in a way as to obtain products having high precision by disposing movable liners supported ascendably to a moving frame utilizing the principle of roller into the spaces between the many stationary liners juxtaposed to the sand molds on top of a base frame. CONSTITUTION:Molded sand molds are moved by each piece while the molds are successively and continuously joined and are placed in this state atop stationary liners 2 and movable liners 2'. Lifting pressure is acted to the sand mold array 6 on top of the liners 2 and the mold is allowed to stand by while 4/5 of the load of the array 6 is held supported by the liners 2' and 1/5 by the liners 2 in the case of ejecting one sand mold 6' formed by a molding machine. The mold 6' is then joined to the front face of the array 6 and pressing force is acted thereto to move the liners 2' together with a moving frame 3 supported via rolling rollers without driving power by as much as the width for one mold 6'. Therefore, even if the may arrays 6 are placed atop the liners 6', the liners 2' are easily moved with the light pressure by the pattern board of the molding machine owing to the effect of the rolling friction force between the frame 3 and the rolling wheels, by which the contact friction force between the liners 2 and the array 6 is decreased considerably and is absorbed into the rolling friction force.
