Title: Iron or iron alloy coated with corrosion resistant layer and manufacture thereof
Inventor: NEMOTO KEIJI
IPC: C23C10/30
Filed: 1978-01-28
Abstract: PURPOSE:To form a coating layer with superior corrosion resistance on the surface of a substrate of iron or its alloy by applying a viscous coating liquid contg. Ti and Ni-contg. powder and a binder, followed by heating. CONSTITUTION:Ti or Ti cpd. powder such as Ti hydride and Ni or Ni alloy powder such as carbonyl nickel are blended in a predetermined ratio and suspended in an aq. soln. of a binder such as CMC. The resulting coating liquid is applied on the surface of a substrate of iron or its alloy, dried, and heated at 900-1200 deg.C for about 10min-2hr to form a Ti-Ni alloy layer contg. 4-45 wt% of Ni on the surface as well as to volatilize the binder. By this method the substrate surface and the layer are fused to form intermetallic bonds of iron-Ti and iron-Ni on the boundary, resulting in a coating layer with superior corrosion resistance.

Title: Method for extracting contour and storage medium
Inventor: KONDO TOSHIAKI
IPC: G06T5/00
Filed: 1999-01-18
Abstract: PROBLEM TO BE SOLVED: To accurately extract a contour of a thin and long object by detecting an edge strength from a received image, correcting the edge strength in response to a magnitude of a predetermined weight coefficient, setting a first target point of tracing the contour and selecting a vicinity pixel with a largest value of the corrected edge strength for a succeeding contour point. SOLUTION: First image data being a processing object are loaded to an image memory or the like, and an edge component is detected from the image data loaded in this image memory. Then pixels to start and to complete contour tracing are designated. The tracing start pixel is a first target pixel. A homogeneity coefficient decided depending on the distribution of a direction θ of the edge is multiplied with the edge strength E to calculated a corrected edge strength E'. After calculating the corrected strength E', a pixel whose corrected edge strength E' is maximum is retrieved for pixels in the vicinity of the target pixel. The retrieval can efficiently be conducted by employing a mask to limit the retrieval range.

Abstract: PURPOSE:To provide a zinc-plated product having flat and uniform appearance, by, in hot Zn dipping in a box having nonoxidizing or reducing atmosphere, soldifying the molten Zn adhered to the steel sheet in the air instead of in the box described above after wiping for controlling plated quantity. CONSTITUTION:A cold rolled coil 1 is surface-cleaned through reducing annealing in a mixed gas 2 of a composition, e.g., 10% H2-N2, then molten Zn is adhered to one side of the coil by an electromagentic pump 3. Excess molten Zn, which is, e.g., at 440 deg.C and which is adhered to the surface of the coil 1, is wiped off with a hot wiping gas 4 which is at 450 deg.C, and the coil 1 is pulled out to the air with the Zn adhered to the surface unsolidified, and the molten Zn is solidified in the air. This method forms plated surface of good quality, having no irregularity because of the increase in flowability (decrease in viscosity) of the molten Zn caused by the oxidation of the hot dipped surface.

Title: Control circuit for rectifying device
Inventor: WASHIO TOSHIFUMI
IPC: G05F1/56
Filed: 1986-01-20
Abstract: PURPOSE:To keep the load voltage at a fixed level with no sudden change by using a control circuit which detects the load voltage and controls the voltage of a load voltage control transistor. CONSTITUTION:This device consists of a constant voltage rectifier 1, a power supply accumulator 2, a load voltage control transistor TrQ1, and a control circuit 3 which controls the TrQ1 after detection of the load voltage. A comparator 3 of a control circuit 3 compares the voltage of a reference voltage source VF with the voltage obtained by dividing the load voltage by resistances R4 and R5. In a normal mode, the output of a comparator CP is set at a high level against the voltage of the VF by said divided voltage and then set at a low level when the load voltage is set at a high level. The output of the CP controls the current flowing to the base of the TrQ1 which controls the load voltage via the TrQ2 and Q3. Thus the collector-emitter resistance of the TrQ1 is varied to raise and fall the output voltage level.
