Title: Blooming method for steel ingot
Inventor: YAMAMOTO AKIO
IPC: B21B45/02
Filed: 1978-02-08
Abstract: PURPOSE:To improve the yield of the blooming, by water cooling the top and bottom portions of the steel ingot after taking away from the soaking pit, so as to give a specified temperature dfference between the surface and interior, and further, by performing the rolling on the bottom at a limited draft percentage under a strong rolling load in the latter half of the rolling pass schedule. CONSTITUTION:The steel ingot 1 taken away from the soaking pit 3 is placed on the carrying table 5 of the blooming mill 4; and then, the top portion T and the bottom portion B of the steel ingot 1 are water cooled by the ring type sprays 61 and 62 so as to make 150 deg.C or more lower the surface temperature of the steel ingot than the internal temperature. After that, in the case of the blooming, the rolling is carried out under a strong rolling reduction taking the ratio of draft percentages between the bottom rolling and the top rolling as above two, at the latter half of the pass schedule. Hereby, the molten steel at the axial center portion relatively satisfactorily stretches being spread as far as the end portions, so that the folding defect and the segregation at the top and bottom portins are extremely reduced.

Abstract: PURPOSE:To obtain a delay line with less area than a conventional line and having the same delay time as a conventional line by combining a 90 deg. direction switch turning the propagation direction of a surface acoustic wave by 90 deg. with a converter and mounting the combined component on a piezoelectric substrate. CONSTITUTION:A converter 2 converting an electric signal and a surface acoustic wave and a 90 deg. direction switch 8 switching the propagation direction of a surface acoustic wave by 90 deg. are provided on the piezoelectric substrate 1. The converter 2 and the switch 8 are formed by etching the metallic film made of aluminum, etc. Dotted lines with an arrow represents the propagating direction of a surface acoustic wave.

In case of the line number NT, the surface acoustic wave made incident on the terminal 11 is completely transferred to a terminal 14 and does not appear at a terminal 12. Thus, the propagating direction of the surface acoustic wave is switched by 90 deg..

Abstract: PURPOSE:To reduce the number of means to be operated and enable the secure feed and cutting of recording paper to be performed without error through easily memorized and simple operation by shutting off the operation of cutting means and only feeding recording paper. CONSTITUTION:A central control 8 judges whether or not a unit is in 'standby' condition.

When the key 9b has been operated, the control 8 monitors the status of an output from a sensor 11 and judges if a cover 4c of recording paper is opened. When the cover 4c is not open, the control 8 drives a cutter 12 and cuts the paper 4b to a prearranged size. Then the control 8 drives a feed roller 13 to feed a prearranged amount of recording paper and ejects only a cut recording paper sheet. In addition, when the cover 4c is open, the control 8 only feeds recording paper by feed roller 13, 14, and finishes processing without cutting.

When the resin binder in the sheet is water soluble, an adhesive agent for this purpose, which is easily soluble into a organic solvent, is employed as the adhesive agent but when the resin binder is easily soluble into organic solvent, water soluble adhesive agent is employed for the adhesive agent of this purpose. When the sheet is adhered to the substrate in the shape of dots or reticulated shape and the substrate is thrown into a furnace to burn it in such a manner, the fine powder of glass in the sheet is molten and a molten glass layer is formed on the surface of the substrate whereby foreign materials in the atmosphere in the furnace are adhered to the substrate and are removed.

Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a production method of circuit board in which adhesion between an insulating basic material and an underlying plating film can be enhanced without roughening the surface of the insulating basic material. SOLUTION: An insulating basic material 1 is made of a resin composition of a polymer compound having an amide group in molecule. An underlying plating film 2 is formed on the surface of the insulating basic material 1. At least the boundary region of a circuit part 3 and a non-circuit part 4 on the insulating basic material 1 is then irradiated with electromagnetic wave, e.g. laser, according to a pattern at the non-circuit part 4 thus removing the underlying plating film 2 from the irradiated part and leaving the underlying plating film 2 in the unirradiated part. Since the insulating basic material 1 contains a polymer compound having an amide group in molecule, adhesion to the underlying plating film 2 is enhanced and the underlying plating film 2 can be formed using an insulating basic material 1 not subjected to surface roughening.
