Title: Apparatus for magnetic flaw detection of thin steel plate
Inventor: TAKENAKA MASAKI
IPC: G01N27/83
Filed: 1990-09-25
Abstract: PURPOSE:To enhance the detection accuracy of a flaw by receiving a magnetizer for forming a magnetic path and each magnetic sensor for detecting leakage flux in separate hollow rolls. CONSTITUTION:When a thin steel strip is allowed to run in the direction shown by an arrow at constant speed, a lower hollow roll 14b is rotated in the direction shown by an arrow. Since an upper hollow roll 14a is energized downwardly by a spring, it is rotated in the direction by an arrow. When a magnetizing power supply apparatus 17 is started to supply an exciting current to an exciting coil 28, a closed magnetic path is formed by a magnetized iron core 26 and the steel strip 12 during running. When a flaw is present in the steel strip 12 or on the surface thereof, the magnetic path in the steel strip 12 is disturbed and leakage flux is generated. This leakage flux is detected by each magnetic sensor and outputted as a magnetic flux detection signal to be inputted to a signal processing circuit 18. The signal level of the inputted magnetic flux detection signal is compared with the reference signal level predetermined by each comparing circuit and the signal equal to or more than the reference signal level is judged as a flaw and outputted as a flaw signal through an alarm circuit 19 to be sent to a flaw counter 20.

Title: Tungsten wire
Inventor: INOUE HIROSHI
IPC: B41J2/25
Filed: 1984-12-04
Abstract: PURPOSE:To prevent the oxidation and embrittlement of a tungsten wire by high-temp. heating and the deterioration of the mechanical characteristics thereof by forming a blue tungsten oxide layer on the polished surface of the drawn tungsten wire and subjecting the surface thereof to nickel plating to a specified thickness or above. CONSTITUTION:The drawn tungsten wire of which the surface is polished is put into an electric furnace in which an oxidation atmosphere of about 450-900 deg.C is maintained to form the blue oxide layer composed of W18O49+W20O58 on the surface thereof. The surface is then subjected to the nickel plating to >=0.1mu thickness. NiWO4 is formed between the layers when the tungsten wire is heated. The inter-diffusion is thus prevented and the oxidation and embrittlement are provided. The deterioration of the mechanical characteristics is prevented as well. The blue oxide is exposed and NiWO4 is not formed if the thickness of the nickel plating layer is <=0.1mu. Then there is the possibility of disconnection owing to oxidation.

Abstract: PURPOSE:To stabilize a light reception level in the operation of a movable member even if a source voltage varies by opening the optical path from a light emission part to a light reception part before the movable member begins to operate, and increasing the driving current of the light emission part so that the light reception level is a stationary level. CONSTITUTION:The optical path from the light emitting diode 2a of the projection part to the phototransistor 2b of the photodetection part is opened and closed with a slit provided associatively to the shutter blade 1 of the movable member and a signal level V1 obtained by the photodetection part is compared with a reference level V0 to detect the position of the blade 1 with the obtained pulse. At this time, the optical path from the light emission part to the light reception part is normally opened with the blade 1 and the voltage V1 generated by a resistance 3 is applied to the opposite-phase input of a comparator 4. Further, the reference voltage V0 generated by a resistance 6 is applied to the in-phase input of the comparator 4 by a constant current source 5. Then, those are compared to increase the driving current i0 of the diode 2a until the voltage V1 exceeds the voltage V0, and the current i0 is fixed at the point of time when the voltage V1 exceeds the V0.
