Title: Air electrode for liquid fuel cell and liquid fuel cell using it
Inventor: UCHIDA MAKOTO
IPC: H01M4/86
Filed: 1990-04-11
Abstract: PURPOSE:To suppress the characteristic reduction of an air electrode due to the methanol permeated from a fuel electrode and obtain the air electrode for a high-performance liquid fuel cell by adding a solid polymer electrolyte in the air electrode. CONSTITUTION:An air electrode has a two-layer structure of a water-repellent layer 22 and a catalyst layer 21. The water-repellent layer 22 is made of carbon fine powder water repellence-processed with polytetrafluoroethylene (PTFE) 25, it is a completely water-repellent porous body, thus it blocks an electrolyte 28 from an electrolyte chamber 24, and air is fed into the catalyst layer 21 from an air chamber 23. The catalyst layer 21 is made of the carbon fine powder 26 water repellence-processed with the PTFE 25 and the carbon fine powder carrying a platinum catalyst 27, it has a less PTFE quantity than the water-repellent layer 22, it is quasi-water repellent, thus the electrolyte 28 from the positive electrode electrolyte chamber 24 infiltrates into the catalyst layer 21. When a solid polymer electrolyte 10-50wt.% is added into the catalyst layer 21 of the air electrode, the diffusion of the methanol in the sulfuric acid electrolyte 28 into catalyst grains is blocked, and the methanol-resistant characteristic of the air electrode is improved.

Title: Method for decreasing non-metallic inclusion in continuously cast slab
Inventor: TANMACHI KENICHI
IPC: B22D11/10
Filed: 1985-05-08
Abstract: PURPOSE:To decrease the integration of the fine inclusions in a molten steel stagnating zone by using an electromagnetic stirrer provided to a support roll zone right under a mold to induce the ascending flow of the molten steel above a prescribed speed. CONSTITUTION:A static magnetic field and electromagnetic brake device 1 is provided in the mold to attenuate the flow rate of the molten steel discharging and flowing out of an immersion nozzle 2 in the stage of casting continuously a slab of an aluminum killed steel, etc. The electromagnetic stirrer 4 is disposed in the position of the casting mold 5 corresponding to support rolls 3 right under the mold 3. The ascending flow 8 of the molten metal toward the molten metal surface at least at >=0.3m/min is induced by the stirrer 4. The stagnating region of the flow is thus eliminated by the quick rise of the dispersing flow 7'. The integration of the inclusions in the molten steel stagnating zone right under the mold is thereby considerably decreased.

Title: Register control system
Inventor: ITO MIKIO
IPC: G06F9/38
Filed: 1985-05-07
Abstract: PURPOSE:To study easily the factor of a designing mistake or a hardware trouble by checking simultaneously the number of a register which is replaced through an instruction executing part and the number of another register whose registration for inhibition of use is erased in response to said replacement of the register number. CONSTITUTION:A register erasing means 30 erases the registers registered to a storage means 10 every time a register waiting for replacement is replaced in the same order of the registration mode. A comparison means 41-48 check the coincidence between a register where an instruction supply part tried to perform a reading action by the subsequent instruction word and each register stored in the means 10 and waiting for replacement. A control means 50 for waiting of register replacement controls the instruction supply part when the coincidence is obtained from said comparison so that no reading action is carried out until the register waiting for replacement is erased. A detecting means 80 checks the discordance between a register to be replaced by the instruction executing part and the register designated by the means 30 for erasion corresponding to the replacement. Then an error is displayed when said discordance is detected. In such a way, a registration mistake or a replacement mistake is detected and the factors of these mistakes can be studied easily.

Title: Vacuum heat insulating material and manufacture thereof
Inventor: HAYASHI CHIE
IPC: F16L59/06
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To improve heat insulating performance without increase in solid heat conductivity by mixing powder with a grain size within one specific range and powder with a grain size within another specific range together for using the mixture as a core material for a vacuum heat insulating material. SOLUTION: A vacuum heat insulating material 1 consists of a core material using powder with grain sizes showing volume frequency peaks at 100-400 μm and at 1-50 μm in a histogram representing a volume frequency to a grain size and a coating material covering the core material. Because these kinds of powder 4 is applied to the core material for the vacuum heat insulating material 1, a void in the powder is reduced and gas heat conductivity is reduced, while increase in conduction points between the powder is lowered and solid heat conductivity is not also increased, and consequently a heat insulating material with excellent heat insulating performance can be provided.  As the grain sizes of the powder 4 are limited within a range of 100-400 μm and within a range of 1-50 μm, the vacuum heat insulating material 1 excellent in both of gas heat conductivity and solid heat conductivity can be provided.
