Title: Method and device for forming gradient magnetic field and magnetic resonance image pickup device
Inventor: MIURA NOBUYUKI
IPC: G01R33/385
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To prevent an artifact due to a magnetic field outside an effective image pickup range by taking a side where the end whose distance from the center of space is shorter exists as the side for applying a gradient magnetic field in the same direction as the magnetostatic field among the end parts of an object to be image-picked up on one and the other sides related to the center of space. SOLUTION: An object to be image-picked up is loaded on an image pickup table, and carried in the internal space of a magnetostatic field generating part. At this time, when the waist of the object 8 to be image-picked up exists in the peripheral area (d), a magnetic resonance signal produced in that part causes an artifact. Then, by a switching device in the gradient driving part, the polarity of the gradient driving signal is switched. That is, the side where the end whose distance from the center O of space is shorter exists is taken as the side for applying a gradient magnetic field (d) in the same direction as the static magnetic field (a). In this condition, the peripheral area (d) is positioned at the tip of the head of the object 8 to be image- picked up.  Therefore, the image pickup object 8 does not exist in the peripheral area (d), so that a magnetic resonance signal causes the artifact is not produced.

Title: X-ray diffraction apparatus
Inventor: HASHIMOTO SEIJI
IPC: G01N23/207
Filed: 1983-06-30
Abstract: PURPOSE:To shorten a measuring time by stopping the masuring repetition when the measured value of diffracted X-ray peak exceeds a prescribed value or the measured value at a position where diffracted X-ray is not present exceeds another prescribed value in repeating the measurement due to fixed time method and adding every time measured results. CONSTITUTION:X-ray counted values at the same angular position of an X-ray detector are added at every angular position. If the added result of measured values at a position where a diffracted X-ray peak exists and a point B expected previously exceeds a prescribed level Vp, the measuring repetition is stopped at the measurement of said time. In case the diffracted X-ray peak is not presented at the position expected from the sample, the added result of the measured value at the point B can not attain to the VP. Even in such a case, the measurement is stopped at the time when the added result of measured values at the position A where the diffracted X-ray peak is not present has attained to another prescribed level Vl. Therefore, the meaningless measurement repetition for an infinite time is prevented.

Abstract: PURPOSE:To track the tail end of a high temperature material to be rolled highly reliably, by detecting the passing of the front-end position of a zone through the point just under a detector of the material, and outputting the detecting result of other tail-end tracking circuit corresponding to the presence or absence of the change of the detecting signal. CONSTITUTION:An existing zone of the tail end of a hot rolled steel sheet 6 is set by using a setter 100. When the rolling at a finishing mill 4 is finished, an output signal of a load cell 16 changes to off, and then the 1st tail-end tracking circuit 40 begins to track and, at the same time, a zone tracking circuit 60 begins to track the front end position of the zone. Even when an output signal of a hot-block detector 20 changes to off caused by the attachment of waterdrops onto the sheet 6, etc., the 1st discrimination circuit 70 discriminates whether the zone front-end reaches the position of a detector 20 or not, because the 2nd tail-end tracking circuit 50 tracks it. The output is inputted to the 2nd discrimination circuit 80 to output the tracked result of the circuit 50 by the circuit 80, and the tracked result of the circuit 40 is outputted when a signal change is not obtained from the detector 20. The output is inputted to a stopping circuit 90 of a coiler.
