Title: Multilayer electrode wiring method
Inventor: IWAMATSU SEIICHI
IPC: H01L21/28
Filed: 1988-03-29
Abstract: PURPOSE:To form a wiring without any disconnection or step disconnection at a hole part by a method wherein a two-layer structure comprising a WSi film and an Al film is used to wire a lower layer electrode through a contact hole made in an insulating film and then the Al film is laser-annealed to be recrystallized. CONSTITUTION:A diffused wiring layer 2 to be a lower layer wiring and an SiO2 film to be an insulating film are formed on a semiconductor substrate 1. Next, a hole is made in the film 3 part above the layer 2 to form a WSi film 4 and then an Al film 5 is formed by sputtering process. The film 5 comprising polycrystal and subjected to inferior build-up properties in the contact hole part is formed into a recess. Thus, when the surface of the film 5 is photo- annealed 6 by laser beams, the film 5 is fused to be recrystallized into single crystal or in large size while the contact hole part is filled with Al to flatten the surface thereof. Through these procedures, an Al wiring can be formed without any disconnection due to migration or any step disconnection in the contact hole part.

Title: Paper money discriminating device
Inventor: ISHIDA TAKESHI
IPC: G07D7/20
Filed: 1989-03-30
Abstract: PURPOSE:To exactly discriminate a paper money even when a pattern is changed for each paper money due to the difference between a new and old paper money and the unevenness of print density by calculating a ratio between the whole integrated value of a whole integrating means and a block integrated value, which is stored to a storing means, and normalizing the size of the pattern to be formed in each block. CONSTITUTION:The paper money decomposed to the 32 blocks, for example, is passed through a detection part 11 to detect the bright and dark distribution of the paper money and an output signal to express the bright and dark distribution is obtained. Then, the output signal is divided into two, one signal is added to a block integrator 12 and the other signal is added to a whole integrator 13. Block information from the integrator 12 are stored to a storage part 14 and the output of the part 14 is made smooth by a smoothing part 15. Then, whole information from the integrator 13 are directly inputted to a normalization part 16. After that, the output of the smoothing part 15 is sent to the normalization part 16 and synthesized. Then, the output is inputted to a difference arithmetic part 18 together with a standard intensity distribution pattern, which is stored to a pattern storage part 17, and the obtained difference is integrated by a difference integrator 19. Thus, the quality of the paper money is discriminated in a discrimination part 20 by using the difference integrated value which is obtained by the difference integrator 19.

Title: Preparation of plasma cvd semiconductor device
Inventor: ABE MASAYASU
IPC: H01L21/205
Filed: 1982-05-10
Abstract: PURPOSE:To improve close contactness between the CVD film and base material by washing the coating surface of substrate with one or two or more kinds of ions selected from the ion seed of particular substance during the period from installation of substrate into the CVD apparatus to just before coating of the CVD film thereon. CONSTITUTION:After an aluminum wiring substrate is installed, for example, in the CVD apparatus kept at 400 deg.C, the CVD apparatus is once vacuumed and is purged using the nitrogen gas. Thereafter, the substrate is uniformly heated for 15-60min in view of equalizing thickness of the CVD film. Next, preprocessing of oxygen plasma is carried out. As the plasma seed used for plasma washing, one or two or more kinds of ions are selected in accordance with substrate material on which the ion is coated, plasma CVD film, and kind of contamination adhered or absorbed to the substrate. In case a silicon nitride film is to be coated on the substrate consisting of a silicon oxide film and aluminum wiring film, the capability of close contactness becomes higher in the sequence of N<O<Ar(He, Ne)<C<F. Particularly, since an organic substance often becomes a source of contamination, the oxygen ion or argon ion is desirable.

Title: Production of broken stone
Inventor: SATO TETSUJI
IPC: B02C19/18
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To efficiently produce broken stones by increasing strength of raw stone to easily suppress a generation of dust. SOLUTION: The raw stone quarried from the rock ground is adequately crushed in a size easy to handle, and then is made into a water-absorbed state by immersing in water, e.g. a water storage pool, for a specified hour. Next, the stone is taken out and the water absorbed raw stone is cooled and frozen by using various freezing equipments. Besides, the cooled and frozen raw stone is charged into a crusher in a frozen state as it is, and the raw stone is crushed up to a specified particle size. The raw stone cooled and frozen after absorption of water increases the strength, thus a generation of dust is easily suppressed.

Title: Pressure regulator
Inventor: MATSUMOTO TOMOHIDE
IPC: F16K17/30
Filed: 1982-05-08
Abstract: PURPOSE:To reduce the fluctuation of the outlet pressure to the inlet pressure, by constituting a pressure regulator by a rough pressure-regulating section and a fine pressure-regulating section. CONSTITUTION:A pressure regulator is constituted by disposing a rough pressure-regulating section 22 consisting of a first valve seat 13, a first valve body 14 and a first diaphragm 17 and a fine pressure-regulating section 31 consisting of a second valve seat 23, a second valve body 24 and a second diaphragm 25 at the portion of a fluid passage located between a fluid inlet port 11 and a fluid outlet port 12. With such an arrangement, pressure is regulated to a certain extent at the rough pressure-regulating section 22, and then the outlet pressure is set accurately at the fine pressure-regulating section 31, so that change of the outlet pressure to the inlet pressure can be reduced. Further, since both of the rough and fine pressure-regulating sections do not require especially high control characteristics, it is not necessary to use a large value as the ratio of the effective pressure receiving area of the valve body to that of the diaphragm. Therefore, it is enabled to reduce the size of the pressure regulator as a whole.
