Title: Manufacture of carbon monoxide
Inventor: SANO KOUZOU
IPC: C01B32/40
Filed: 1979-08-17
Abstract: PURPOSE: To obtain methanol and high purity CO by thermally decomposing methyl formate alone in a methyl formate-methanol mixture in the presence of a specified alkali metal compound to improve the selecting rate and decomposing rate.  
     CONSTITUTION: Methyl formate alone in a methyl formate-methanol mixture is thermally decomposed in the presence of an alkali metal compound such as potassium hydroxide or sodium sulfate as catalyst other than alkali metal alcoholates to obtain methanol and CO. The amount of the catalyst used depends on the utilization form, and for example, in case of a fixed bed type continuous method the catalyst amount is not especially restricted. When the catalyst is mixed into the starting material mixture or the catalyst and mixture are fed to a reactor separately and simultaneously to perform the reaction batchwise or continuously, the amount of the catalyst used is 0.1W400mg atom as alkali metal atom per mol of methyl formate.

Abstract: PURPOSE:To smoothly control the speed of a DC motor at low speed rotating time by providing an oscillator generating higher frequency than the AC power source when driven by the outputs of a full-wave rectifier circuit and determining the sampling period of the speed detection with the output of the oscillator. CONSTITUTION:An oscillator having an integrated circuit Q21, resistors R23, R24, and a capacitor C21 is provided in a speed controlling circuit connected in series with a feeding controlling transistor Q6 and a DC motor M1 at the output side of a full- wave rectifier DB21 to obtain a higher frequency output signal than the power source frequency.

Title: Annealing apparatus
Inventor: KATOU MAMORU
IPC: C21D1/00
Filed: 1978-08-29
Abstract: PURPOSE:To anneal the material to be treated in a small construction area and with a relatively small quantity of heat consumption, by installing an endless conveyor in a cylindrical furnace lined with refractory material, and by heating the material to be treated while being conveyed by trays mounted on the endless conveyor. CONSTITUTION:An endless conveyor 3 is installed in a tower 1 lined with refractory material 2 at the top and the periphery thereof. The conveyor 3 has many trays 4 mounted at the outer side thereof and is circulated by sprockets 9, 10, 11. The material to be treated, e.g., coil springs, tips, are dropped through an inlet 7 made in the lower part of the tower 1 to the trays 4 of the conveyor 3. The materials ride on one sides 6 of the trary 4, rise to the top of the tower, where the trays are turned over, so that the materials ride on the other sides of the trays 4. Hereby, the materials are heated and annealed while being conveyed by the conveyor 3, and discharged through an outlet 8. Because this apparatus is a vertical tower, it manges without a large construction area, with a small amount of heat loss caused through the inlet and the outlet for the material to be treated, and makes the annealing possible with a small amount of heat consumption.

Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To discriminate whether to perform a processing by saving processing time or to perform the processing by improving image quality and to perform the processing by selecting which one of a low order interpolation method and a high order interpolation method is to be used for reconstituting three-dimensional images based on a view point and a line-of- sight direction. SOLUTION: The three-dimensional images are reconstituted while arbitrarily moving a view point position and the line-of-sight direction on the three-dimensional images while observing the three-dimensional images displayed on a display screen and an 'updating' button displayed on the display screen 3 is clicked by a mouse 4 for instance. In such a manner, the three-dimensional images are reconstituted by the low order interpolation method. Then, the view point position and the line-of-sight direction are moved and updated on the three-dimensional images 6 displayed on the display screen 3. In such a manner, the three- dimensional images are reconstituted by the low order interpolation method while moving the view point position and the line-of-sight direction.  Also, in the case of performing the processing by improving the image quality of reconstitution images even though long time is required, in the state of obtaining a view point coordinate and the line-of-sight direction accompanying value updating by interpolation, the three-dimensional images are reconstituted by high order interpolation.

IPC: H01M50/531
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To manufacture an electrode structure having a required nickel density by coating a plated porous base material with metallic powder slurry. SOLUTION: A slurry made of nickel powder is applied to a specific area of a porous structure before sintering. The nickel powder is specially effective when its particle diameter is 1 micrometer or less, and its apparent density is about 1g/cc or more. After sintering under conditions necessary for removing organic base material and softening deposits, the overcoat becomes a fine- grained metallic layer. By changing the slurry density or application sequence, density and conductivity may be made maximum in a tab area and gradually smaller toward other areas, as the amount of the metal added may be changed.
