摘要： According to the present invention, an upper electrode and a lower electrode are integrally assembled with insoluble electrodes and diaphragmn in diaphragm electrode structure. Small holes are furnished on the upper electrode, and the diaphragm of the upper electrode is installed obliquely with degassing means. By simply carrying the objects to be plated in horizontal direction, uniform and high quality electroplating can be continuously performed with extensive increase in productivity, while enjoying all of the benefits such as shorter interpolar distance between two electrodes, compact design of the apparatus, saving of expensive additives, etc. Further, the inspection of the diaphragm and the like can be rapidly and easily accomplished, and perfect protection of the diaphragm is assured, thus providing a horizontal carrying type electroplating apparatus suitable for practical use.

摘要： A subirrigation system 10 includes a water-impervious member 16, and keeps water content in soil of a cultivated land 200 in a proper state for growing a plant. The water-impervious member 16 is formed into an upper opening vessel shape, and has a water reserving function. Water is fed to an inner portion of the water-impervious member 16 from a water tank 12 via a feed water pipe 14, whereby a soil portion 26 in a gravitational water state is formed. A water level 28 of the gravitational water within the water-impervious member 16 is properly controlled to a desired water level by a water level controller 18 provided in the feed water pipe 14. The gravitational water within the water-impervious member 16 controlled to the desired water level is appropriately sucked up to the soil in an upper layer in accordance with a capillary phenomenon. Accordingly, a soil portion 30 in a capillary water state having proper water content is formed in the cultivated land 200.

摘要： An electrode comprising a substrate of a conducting metal, a coat of an electrode active substrate, and a layer interposed between the substrate and the coat to serve as a protective barrier for the substrate acquires improved durability by using, as the intermediate layer, a layer having platinum dispersed in a mixed oxide consisting of an oxide of at least one metal selected from the group consisting of titanium and tin, each having a valence of 4, and an oxide of at least one metal selected from the group consisting of tantalum and niobium, each having a valence of 5. The electrode of improved durability is produced by a process which comprises the steps of preparing a substrate of a conducting metal, depositing a solution containing salts of Ti and/or Sn, Ta and/or Nb, and Pt on the substrate, heating the resultant coated substrate under the blanket of an oxidizing gas thereby forming an intermediate layer on the substrate, and subsequently coating the intermediate layer with a layer of an electrode active substance.
