摘要： PURPOSE:To reduce the cost of coenzyme, by adsorbing the coenzyme with an adsorbent, and desorbing and reusing the recovered coenzyme. CONSTITUTION:The reaction vessel 1 is packed with an immobilized enzyme composed of two kinds of enzymes for the main reaction and the regeneration of coenzyme, and an adsorbent 5 is filled in the coenzyme-recovery columns 3, 4. Two kinds of substrate solutions 6, 7 having pH and metallic ion concentration controlled to the desorption condition of the coenzyme are mixed together in the substrate mixing tank 8, and the mixture is supplied to one of the columns 3, 4 to effect the desorption and dissolution of the coenzyme. The effluent from the column 3 is stored in the tank 13, optionally subjected to pH-adjustment, and sent to the reaction vessel 1. Thereafter, it is transferred to the tank 16, adjusted to the adsorption condition of the coenzyme by the addition of a pH-controlling liquid 17 and the metallic salt solution 18 and is supplied to the other column 4 of the coenzyme-recovery columns 3, 4 to effect the recovery of the coenzyme.

摘要： PURPOSE:To produce a resin-sealed type electronic part with excellent reliability especially under high temperature and high humidity by a method wherein antimony and/or bismuth base inorganic ion echanger is blended with an incombustible resin composition blended with diantimony trioxide sealing an electronic part. CONSTITUTION:An electronic part is sealed with an incombustible resin composition containing antimony and/or bismuth base inorganic ion exchanger blended with biantimony trioxide as a flame retarder. Said resin compositon is provided with excellent electric characteristics under high temperature or humidity as well as the least corrosive action on metallic raw materials under high temperature and high humidity. As for antimony and/or bismuth base inorganic ion exchanger, e.g. hydroxide of antimony and bismuth, hydroxide-containing compound, phosphoantimonate, zirconium antimonate etc. are applicable. The finer the particle diameter of said inorganic ion exchanger, the faster the ion absorbing speed and the better the corrosion protective effect when blended with a resin composition.

摘要： PURPOSE:To obtain an electrode excellent in mass productivity, by alternately laminating insulating layers and conductor layers and utilizing the cross-sectional area of the laminate to use the conductor layers as a resistance measuring electrode for a sensor. CONSTITUTION:A large number of conductor layers 5 and insulating layers 4 are alternately stacked. This process can be performed by utilizing a green sheet and thick film printing technique. Because the gaps between electrodes are determined by the thickness of each insulating layer 4, each gap can be reduced to about 10mum. Thereafter, right and left parts are cut and the cross-sectional area exposed by cutting is metallized to connect the conductor layers and a pair of comb shaped electrodes are formed while leads are attached to the metallized parts 6. Because of a structure only cutting the laminate of conductors and insulators as mentioned above, mass productivity is excellent.
摘要翻译：目的：为了获得优异的批量生产率的电极，通过交替层叠绝缘层和导体层并利用层压体的横截面积来使用导体层作为传感器的电阻测量电极。构成：大量导体层5和绝缘层4交替堆叠。该方法可以通过使用生片和厚膜印刷技术来进行。由于电极之间的间隙由每个绝缘层4的厚度确定，所以每个间隙可以减小到大约10微米。此后，切割右部分和左部分，并且通过切割暴露的横截面区域被金属化以连接导体层，并且形成一对梳状电极，同时引线附着到金属化部分6上。由于仅将切割如上所述的导体和绝缘体的层叠体，批量生产率极好。
