Abstract: PROBLEM TO BE SOLVED: To improve the solubility of Al ions and Ca ions in water by composing an inorganic powder of (A) a powder prepared by mixing an Al compound with a Ca compound respectively having water of crystallization in a specific proportion and pulverizing the resultant mixture and (B) a powder composed of the Ca compound having the water of crystallization. SOLUTION: This inorganic powder is composed of (A) a powder prepared by applying a mechanical energy to a mixture comprising an Al compound having water of crystallization and a Ca compound having the water of crystallization and (B) a powder comprising the Ca compound having the water of crystallization. Aluminum hydroxide is used as the preferred Al compound of the powder A and calcium hydroxide is used as the preferred Ca compound. The mixing molar ratio of both the compounds is 10-0.05 expressed in terms of Ca/Al. The mixture is pulverized with a usually used puvlerizer, e.g. a ball mill. The mechanical energy applied thereto at this time is 0.5-30kWH/kg. On the other hand, the Ca compound of the powder B is preferably calcium hydroxide.  Thereby, the solubility of Al and Ca ions in water can be improved and the inorganic powder can be added to a cement to sufficiently promote both the setting rate and hardening rate.

Title: Digital processing ghost elimination device
Inventor: MATSUE HIROSHI
IPC: H03H15/00
Filed: 1991-02-28
Abstract: PURPOSE:To obtain the digital processing ghost elimination device brought into practical use through the reduction of a circuit scale. CONSTITUTION:An output of a subtractor 29 is given to equalization units connected in cascade. Each equalization unit delays an inputted signal by a variable delay circuit in a delay quantity in response to the ghost delay time and gives the result to a next stage equalization unit. The output of a transversal filter of each equalization unit is added to an output from other equalization unit and the output of an adder of a first stage is given to the subtractor 29 as a ghost cancel signal. The subtractor 29 subtracts the ghost cancel signal from a television signal to output an output from which ghost is eliminated. Thus, the ghost in the delay time of a wide range is eliminated with less number of taps.

Title: A/d converter for analysis device
Inventor: KODAMA YOSHITAKA
IPC: H03M1/12
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To eliminate the cyclic generation of noise in the case of inputting DC signals and to eliminate the errors of analysis data by adding sawtooth- shaped waves or triangular waves to input signals and inputting the output to a Δ-Σ type A/D converter. SOLUTION: By making clocks be in common, the cycle of superimposing waveforms and the timing of fetching data are synchronized. Since this Δ-Σ type A/D converter 3 is provided with characteristics incapable of following up rapid change, the stable time of the Δ-Σ A/D converter 3 is waited for after the fall of the sawtooth-shaped waves and the next sawtooth-shaped waves are superimposed. Converted results for one cycle of the sawtooth-shaped waves are integrated. by subtracting the part of the superimposed sawtooth-shaped waves from an integrated value by using a microcomputer, the input signals are obtained. Also, by making a difference between the respective samplings of the superimposing waveform be smaller than the resolution of the A/D converter 3, the converted results are integrated and a higher resolution is made possible.

Abstract: PURPOSE:To perform regulation of a dynamic injection amount and to prevent the occurrence of a trouble, such as the change of an injection amount owing to corrosion and an external force, by arranging a regulating mechanism for a spring to the interior of the spring containing part of a core. CONSTITUTION:A core 3 forms solid structure, the upper end part thereof is covered with plastic, and a regulation bobbin 26 is arranged to the containing part 27 of a spring 9 for regulating a dynamic injection amount. One means for regulating a dynamic injection amount is coupled integrally with a plunger 5 and is slid over the interior of the core 3, and guides a moving valve body 6 which contains a plunger. Further, the height of the guide ring 19 which supports the spring 9 by means of the end surface thereof is regulated by the one means. Besides, a different means inserts a spacer between the spring 9 and the core 3 to effect regulation. This constitution reduces the number of parts and decreases the size of an injection valve itself. Further, since the core 3 is covered with plastic, a trouble, such as the change of an injection amount owing to corrosion and an external force, is prevented from occurring.

Title: Method and device for removing carbonaceous impurity on surface of silicon substrate
Inventor: HIROSE FUMIHIKO
IPC: H01L21/3065
Filed: 1995-02-23
Abstract: PURPOSE: To provide a method and device for removing impurities remaining on the surface of a silicon substrate without performing any high-temperature heat treatment before forming a film on the surface of the substrate by epitaxial growth. CONSTITUTION: After a silicon substrate 1, from the surface of which carbonaceous impurities are to be removed, is set in a vacuum vessel 2 incorporated with a filament 4 while maintaining in room-temperature, the vessel 2 is evacuated to <=1×10<-8> Torr with a vacuum pump 3. After evacuation, an H2 gas 6 is introduced to the vessel 2 until the pressure in the vessel 2 becomes 1×10<-4> Torr and the temperature of the filament 4 is raised to about 1,800 deg.C by conducting the filament 4. As a result, the H2 gas 6 filling the vessel 2 dissociates to atomic hydrogen when the gas 6 collides with the filament 4 and a silicon hydroxide is produced when the hydrogen collides with the substrate 1 and reacts to the silicon on the surface of the substrate 1. When the silicon hydroxide leaves the substrate 1, the hydroxide carries the carbonaceous impurities.
