Title: Thermally decomposing method for water
Inventor: SUMIYOSHI YOSHIMITSU
IPC: C01B3/06
Filed: 1980-08-13
Abstract: PURPOSE: To simply obtain hydrogen for fuel by thermally decomposing water with a metal to produce hydrogen and reducing the by-product metallic oxide to the original metal using CO obtd. in a process for producing hydrogen by the reaction of carbon with steam.  
     CONSTITUTION: By a water feeding means 1, 1mol fine carbon particles are mixed with 2mol water. The mixture is reacted at ≥750°C in the 1st reaction region 2 according to equation I, and excess water and the reaction products are introduced into the 2nd reaction region 3. In the region 3 a metal such as iron or a lower metallic oxide is reacted with hot steam introduced from the region 2 at about 150W 550°C to generate hydrogen according to equation II (where M is the metal), and the hydrogen is led out of the reaction system together with the hydrogen produced in the region 2. The by-product metallic oxide in the region 3 is reduced to the original metal by the reaction of equation II using CO from the region 2, and it is reacted with water again.

Filed: 1987-05-07
Abstract: PURPOSE:To transfer charge in high speed by a method wherein a impurity layer which has a concentration gradient that serves so as to tilt the base of a potential well controlling the transfer of charge is formed on a silicon substrate. CONSTITUTION:P-type impurity in a p-type impurity layer 2 has a concentration gradient under each gate electrode 4, therefore the base of a potential well 5 has a tilt. Two-phase clock pulses phi1 and phi2 are applied onto the gate electrode 5 transferring charge. The potential well 5 is rendered to be into such a state that charge 10 is accumulated at the base of the potential well 5 under the gate electrode 4 applied with voltage V, where phi1=V and phi2=0. Next, when phi1=0 and phi2=V, the charge 10 starts to move in the direction of an arrow toward the potential well 5 under the gate electrode applied with voltage V. In the manner as mentioned above, the charge 10 is drifted so as to move fast as the base of the potential well 5 has a tilt.

Title: Manufacture of flattened permalloy fine powder
Inventor: MUROSHIGE MASASHI
IPC: B22F1/00
Filed: 1990-04-27
Abstract: PURPOSE:To efficiently obtain flattened permalloy fine powder having required shape by executing annealing on the way of pulverizing process for manufacture. CONSTITUTION:On the way of the pulverizing process for manufacturing the flattened permalloy fine powder, one or more times of annealings are executed. By this method, it can be prevented that flattening is not progressed becaused of work hardening by developing strain in the powder at the time of progressing the flattening of fine powder in some degree in the pulverizing process. As a result, the flattened permalloy fine powder having 5 - 40mu average particle diameter, <=2mu thickness and >=10 aspect ratio, is efficiently obtd. In order to prevent sintering of the powder, the annealing temp. must be drastically lowered from the temp. near 1,100 deg.C in the case of bulky material, but by executing the annealing while vibrating or fluidizing with mechanical means, this is executed while preventing the sintering at the comparatively high temp. (400 - 800 deg.C).
