Title: Quenched high silicon steel thin strip excellent in magnetic characteristics
Inventor: SHISHIDO HIROSHI
IPC: C22C38/00
Filed: 1982-08-11
Abstract: PURPOSE:To obtain the titled thin strip having excellent magnetic characteristics and especially remarkably reduced in iron loss, by specifying the plate thickness of the product of a quenched high silicon steel strip and the particle size thereof after annealing. CONSTITUTION:Molten steel containing 2.0-8.0wt% Si is directly formed into a plate by a continuous quenching method wherein molten steel is directly injected onto a rapidly moving cooled body from a nozzle to be rapidly solidified and the plate thickness at this time is adjusted to 40-180mum. In the next step, the surface of the high silicon steel strip is cleaned to be further coated with high m.p. oxide as a release agent and the treated steel strip is wound up in a coil shape which is, in turn, annealed at about 1,100-1,300 deg.C to adjust an average crystal particle size after annealing to 2-10mm.. By this method, a high silicon steel thin strip having an aggregation structure of which the (100) surface is aligned and excellent in magnetic characteristics is obtained.

Title: Formation measuring method and formation controlling method using said formation measuring method
Inventor: YAKABE MASAHIRO
IPC: G01N21/894
Filed: 1989-05-31
Abstract: PURPOSE:To perform accurate determination by dividing the image of transmitted light from a parallel light source wherein the amount of light can be changed into required number of windows, and computing the density for every window. CONSTITUTION:A parallel light source 2 is adjusted so that the amount of light which can be readily received by a camera 3 is obtained depending on the thickness of paper 1. The image which is inputted into the camera 3 is always displayed on a display device 7 as an image 9a of the actual transmitted light. The signal which is inputted into an operating device 5 for image memory 5 is displayed on a display device 6 as an image 9 that shows an area by which the quality of the entire paper 1 can be judged. The image is displayed so that the density of a void part is thinner than average and the density at an excessively heavy part where dust and the like are attached is denser than average. Windows W1 - Wn are set so that a region having the area about twice the minimum size of a flock inherent to the paper 1 is made to be the unit for distribution computation. Thus the formation of the paper can be determined accurately.

IPC: H04B1/707
Filed: 1989-05-31
Abstract: PURPOSE:To attain efficient information transmission by utilizing the correlation of an original signal with strong time correlation such as an analog audio signal and video signal and compressing the component of the original signal. CONSTITUTION:A modulator 3 at a transmission side applies spread modulation to digital code information by using a pseudo random signal generated from a pseudo noise generator 2, the output of the modulator 3 is subjected to arithmetic processing by a computing element 4, a D/A converter 5 converts the signal into an analog signal, an analog adder 7 adds the resultant to an audio signal to a video signal to form a transmission signal. Inverse spread modulators 10-12 at a reception side receive a predictive error signal and a pseudo random signal and demodulates the digital code information subjected to spread modulation included in the predictive error signal. Moreover, the computing element 4 at the transmission side applies inverse processing to the processing obtaining a predictive error signal from the reception signal at the reception side. That is, the digital code information in the reception signal is left as it is, but only the audio signal and the video signal are suppressed. Thus, the information is transmitted efficiently.

Title: Formation of metal wiring in semiconductor device
Inventor: NARA HAJIME
IPC: B05D7/00
Filed: 1994-06-21
Abstract: PURPOSE:To obtain a method for forming a metal wiring in a semiconductor device in which the coverage can be improved in the vicinity of a contact without sacrificing the characteristics of metal wiring. CONSTITUTION:A contact hole 11 is opened by selective etching above the impurity diffusion layers 4, 5 of an interlayer insulating film 6 of SiO2. A metal wiring layer 9 of Al-1%Si alloy is then deposited by sputtering from above a semiconductor substrate 1. An organic plasticizer 10 of tricresyl phosphate is stored, by spin coating, in a recess made in the metal wiring layer 9 closely to the contact hole 11. A high frequency voltage is then applied thereto under a pressure of 5atm in an inert gas atmosphere of N2 thus heating the organic plasticizer. The metal wiring layer 9 melts and flows slowly thus improving the coverage while preventing variation in the crystal structure or generation of pin hole. Subsequently, the atmospheric pressure is recovered and the organic plasticizer 10 is heated and evaporated.

Abstract: PURPOSE:To couple light beams returned from an optical transmission line for measurement by reflection with another transmission line for output without relying on polarization so as to realize highly reliable measurement on the light beams returned by reflection, by using plural double-refraction crystal plates. CONSTITUTION:Two wedge-shaped double-refraction crystal plates 11 and 12 are arranged along an optical axis line in such a way that the optical axes of the adjacent crystal plates can form an angle of 45 deg. in a plane perpendicular to the optical axis line.
