Title: Butt welding method for plate and equipment therefor
Inventor: ISHIZAKA YUJI
IPC: B23K13/00
Filed: 1986-04-04
Abstract: PURPOSE:To operate continuously a hot rolling mill by providing induction heating coils to the upper and lower surfaces of plates arranged in opposition and pressing the abutting surfaces mutually while induction-heating the abutting surfaces of the plates. CONSTITUTION:The thick plates 1 to be joined mutually are opposed via a gap of about 2-3mm and the orthogonal magnetic flux type induction heating coils 2 are provided with the abutting surfaces in-between. Moreover, clamps 4 are provided to the thick plates 1 in opposition and the abutting surfaces can be pressed mutually. When the electric power such as high frequency, etc., is supplied from a power unit to the coils 2, the magnetic flux phi generates induced currents iw1, and iw2 collectively in the neighborhood of the abutting surfaces of the thick plates 1 and the part is heated. On this occasion, since the thick plates 1 are pressed mutually by the clamps 4, the thick plates 1 are joined with the welding in a very short time. Accordingly, the continuous rolling of the hot rolling mill is performed.

IPC: H04N9/093
Filed: 1981-05-23
Abstract: PURPOSE:To make a special lens, a microcomputer, etc. unnecessary and to simplify the constitution of the titled device, by detecting the phase difference of the sampling signals between a reference channel and a channel to be compared and compensating automatically the vertical shift of the registration by the detection output. CONSTITUTION:The light given from a subject is separated by a spectral element and then converted into the video signals by the G and R channel image pickup tubes G1 and R1 respectively to receive the clamping, a nonlinear process, etc. through a preprocessing circuits G2 and R2. The outputs of the circuits G2 and R2 are binary coded by the binary coding circuits G3 and R3. The information of the place corresponding to the vertical axis draw-out line is sampled by the sampling circuits G7 and R7 respectively and then extracted. The sampling values are stored once into the RAMG8 and R8. These stored signals are simultaneously called to a phase comparator 9 in order of the correspondence to the vertical axis draw-out line. The shift of the centering is detected and applied to an R channel registration compensating circuit R0 via a post-processing circuit 6. Thus the compensating is carried out automatically by the output of the circuit R0.

Title: Production of dual-phase stainless steel sheet excellent in formability
Inventor: MAEHARA YASUHIRO
IPC: C21D8/02
Filed: 1981-05-22
Abstract: PURPOSE:To obtain a dual-phase stainless steel sheet excellent in the formability such that loping is not generated on the surface of a formed product, by hot- working and annealing a stainless steel sheet material in a dual-phase temperature range below the point that the stainless steel turns into a single ferritic phase. CONSTITUTION:In the production of a dual-phase stainless steel sheet, a heating temperature during hot-working and an annealing temperature are controlled in a dual-phase temperature range, in a manner such that they do not rise up to a high level to convert the stainless steel into a single ferritic phase. As a result, an austenitic (gamma) phase can be insularly analyzed and precipitated in a ferrite matrix. The growth of ferritic crystal grains is inhibited by the presence of the phase gamma. The insular distribution of the phase gamma in the ferrite matrix can be maintained as such, even after the stainless steel sheet is annealed and then cooled. Moreover, the phase gamma can prevent the generation of an elongated cylindrical grain band comprising the ferritic crystal grains as a unit during press- working. Consequently, the generation of loping on the surface of a product can be inhibited.

Title: Automatic return tester
Inventor: TERUI KOUKI
IPC: H04B17/00
Filed: 1983-05-04
Abstract: PURPOSE:To suppress the time of circuit disconnection as much as possible and to improve the reliability of a circuit by conducting a return test only when an abnormal state continues for a specific time after abnormality of a receiver is detected. CONSTITUTION:An automatic return tester 2 is set normally in a stand-by state. When the receiver 1 becomes abnromal and its detection signal is applied to a logical circuit 3, the circuit 3 drives an oscillator 4 when the detection signal is in the same state continuously for longer than the specific time. A shifter 6 generates a signal of the same frequency with a receiving signal by a signal from the side of a transmitter 5 and a signal from the oscillator 4 and sends out the signal to the receiver 1 through a BPF7 and a coupler 8. When this signal is outputted to the output terminal of the receiver 1, the circuit 3 decides that the receiver 1 is normal, and when no, it is decided that the receiver 1 is faulty. The circuit 3 does not conduct the return test when the abnromality detection signal is ceased within the specific time.

IPC: B62D55/253
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent a wheel from being disconnected and provide selfreturning property by forming a crawler main body internal circumferential face or a rolling wheel traveling face in such a state as becoming lower from the central side to the outside and forming the outer circumferential shape of the rolling wheel into a shape matched with the shape of the rolling wheel traveling face. SOLUTION: Base parts of a lot of core bars 2 are embedded in parallel to each other perpendicularly to the longitudinal direction of a crawler main body which is formed of rubber and two guide projections projecting to the inner part than the internal circumferential face of the crawler main body are formed respectively in the core bars 2. A rolling wheel 3 of a machine body travels on the inner circumferential face of the crawler main body in both sides of the guide projections. When the rolling wheel 3 is about to be disconnected, the outer circumferential face of the rolling wheel 3 is inclined just like the rolling wheel traveling face 6 so that it is hard to be disconnected and return to its original position. The formation of rolling wheel 3 and the rolling traveling face 6 having such inclination makes the wheel hard to disconnect and provides with the self-returning property.
