IPC: C22C38/58
Filed: 1987-07-13
Abstract: PURPOSE:To produce a nonmagnetic steel which has high strength and is less softened in weld heat-affected zone by subjecting a high-Mn steel added with a small amt. of Nb to hot rolling at a controlled heating temp. and rolling finish temp. and further controlling the accelerated cooling conditions after cooling. CONSTITUTION:A steel ingot or billet consisting, by wt.%, of 0.10-0.40% C, 0.05-2.50% Si, 18-30% Mn, 0.01-0.10% Nb, 0.005-0.200% N, and the balance Fe and unavoidable impurities is heated to >=1,000 deg.C and <=1,250 deg.C and is subjected to the hot rolling which is completed at >=800 deg.C. The rolled steel is then subjected to the accelerated cooling by water cooling at 1-50 deg.C/sec average cooling rate from 800 deg.C down to 500 deg.C. The high Mn nonmagnetic steel which is less softened in the weld heat-affected zone and has the high strength is thereby obtd. This steel is adequate for a nonmagnetic structural material to be used for nuclear fusion reactors and linear motor cars.

Title: Measuring device for delay time
Inventor: NAKATSUGAWA KENJI
IPC: G04F10/06
Filed: 1984-08-22
Abstract: PURPOSE:To easily measure the propagation delay time of a body to be measured by applying an input signal swept from an optional frequency F0 to specific frequencies (F1-F2) to the input terminal of the object body, detecting phases theta1, theta0, and theta2 corresponding to the frequencies F1, F0, and F2 and a phase rotation part from an output terminal, and calculating a mean delay time from a specific equation. CONSTITUTION:A sweep oscillator part 11 controls a frequency control part 12 so that a signal is swept to a specific frequency width F1-F2 including the optional frequency F0. The oscillator part 11 is divided into two so as to measure phase characteristics of the object body 13 having delay characteristics; one is connected directly to a phase difference detection part 14 and other is connected through the object body 13. A mean delay time arithmetic circuit 19 calculates the mean delay time with signals of a phase detecting circuit 17 and a phase rotational frequency detecting circuit 18. For example, when the phase at a frequency F0 is theta0, a delay time arithmetic circuit 23 calculates the delay time according to whether the input and output of the object body 13 are in phase or out of phase. Consequently, the delay time is measured by the simple measurement system at a high speed.

Title: Production of thick film pattern and dry film resist used for its production
Inventor: NAKAMURA RYUICHI
IPC: G03F7/40
Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to obtain uniform thick film patterns decreased in defective articles by constituting the resists laminated on a base film of plural layers of different color tones. SOLUTION: The dry film resist 50 is composed of the base film 40, a first layer resist 50, a second layer resist 60 and a cover film 70. The components of the photosensitive resins constituting the first layer resist 50 and the second layer resist 60 may be the same or not. These resins are, however, colored in such colors as yellow and blue, which are discriminable from each other by observation with naked eyes, etc. If the resists are formed in the two layers, the color tones of the respective layers vary like, for example, the first layer resist 50 is yellow and the second layer resist 60 is blue but in the case of >=3 layers, all the layers may be or may not be changed to the different color tones.  As a result, the second layer resist 60 of the color tone different from the color tone of the first layer resist 50 appears when the first layer resist 50 of a female mold is completely polished. Consequently, the easy checking of stock removed is made possible.
