Title: Method for decomposing methanol
Inventor: KIYOURA TADAMITSU
IPC: C01B3/32
Filed: 1990-06-25
Abstract: PURPOSE:To enable highly efficient decomposition of methanol without deteriorating catalyst activity by decomposing the methanol in the presence of a catalyst containing chromium oxide and zinc oxide as principal components with limited contents of iron and nickel and a specific compound added thereto. CONSTITUTION:Methanol or a mixture thereof with water is decomposed in the presence of a catalyst consisting essentially of chromium oxide and zinc oxide to produce a mixed gas of CO and H2. In the process, operation is performed as follows. That is the decomposition is carried out in the presence of the catalyst, having contents of iron and nickel therein respectively kept at <=0.5wt.% and containing a compound of one or more elements of alkali metals, alkaline earth metals and lanthanide group added thereto. The aforementioned decomposition reaction of the methanol is conducted by using the methanol of >=99% purity or the mixture of the methanol with water. The amount of the water fed together with the methanol to a reactor is normally regulated depending on the required ratio of H2 to CO.

Title: Semiconductor circuit and formation thereof
Inventor: YAMAGUCHI NAOAKI
IPC: H01L29/786
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To simplify the process by reforming at least a part of wiring into an anode oxide through an anodic oxidation process thereby insulating and breaking the wiring electrically through single anodic oxidation. SOLUTION: An anodic oxidation AO wire 201 is constricted partially to form a thin wire part 202. When anodic oxidation is started under that state, an oxide is deposited gradually on the surface touching a catalytic solution and the AO wire 201 becomes thinner as the thickness of the oxide increases. When the anodic oxidation is continued, the AO wire is entirely subjected to anodic oxidation at the thin wire part 202. More specifically, the thin wire part 202 is insulated to lose the electric conductivity and it is broken electrically. According to the method, the AO wire is broken automatically at the time of anodic oxidation without requiring any breaking process by simply making thin a part of the AO wire at the time of patterning a first wiring.

Abstract: PURPOSE:To obtain an opened angle which is greater than a stroke of an elastic pushing up member by interposing the elastic pushing up member and a rod to obtain the opening angle of a top unit between the top unit and a bottom unit. CONSTITUTION:A gas spring 4 and the rod 5 with one edge connected to the spring 4 are interposed between the top unit 2 and the bottom unit 1, the other end of the gas spring 4 is attached to the side of the top unit 2 and the other end of the rod 5 is pivotally attached to the side of the bottom unit 1 as a rotation supporting point 6. The gas spring 4 is used as a constituent of the elastic pushing up member and a force acting in the direction opposite that of a force acting to rotate the unit in a closing direction is generated due to gravity of the top unit 2. When the top unit 2 becomes in a state where it is inclined and opened at the maximum opening angle, the gas spring 4 becomes in an approximately vertical state and the rod 5 becomes in an inclined state. Therefore, the opening angle of the top unit 2 can be obtained which is greater than the stroke of the gas spring 4 approximately by the length of the rod 5.
