Provided is a nitride semiconductor having a larger low-defective region on a surface thereof, a semiconductor device using the nitride semiconductor, a method of manufacturing a nitride semiconductor capable of easily reducing surface defects in a step of forming a layer through lateral growth, and a method of manufacturing a semiconductor device manufactured by the use of the nitride semiconductor. A seed crystal portion is formed into stripes on a substrate with a buffer layer sandwiched therebetween. Then, a crystal is grown from the seed crystal portion in two steps of growth conditions to form a nitride semiconductor layer. In a first step, a low temperature growth portion having a trapezoidal-shaped cross section in a layer thickness direction is formed at a growth temperature of 1030° C., and in a second step, lateral growth predominantly takes place at a growth temperature of 1070° C. Then, a high temperature growth potion is formed between the low temperature growth portions. Thereby, hillocks and lattice defects can be reduced in a region of the surface of the nitride semiconductor layer above the low temperature growth portion.

A resin-coated Al—Zn alloy coated steel sheet is excellent in formability, resistance to chromium dissolution, corrosion resistance, alkali resistance, and paintability, and produced by the following method. That is, a silane coupling agent having amino group, chromium ion and at least one alcohol selected from the group consisting of trihydric alcohol and dihydric alcohol having the number of carbon of 2 to 3 are compounded into an acrylic polymer resin emulsion including carboxyl group and glycidyl group, and having an acid value of 10 to 60. A pH of the resultant mixture is adjusted within a range of 7 to 9 to obtain a chromate containing resin composition. The chromate containing resin composition is applied on an Al—Zn alloy coated steel sheet as a substrate, and then dried to obtain a resin film on the substrate. A compounding amount of the silane coupling agent is within a range of 0.5 to 3.0 wt % with respect to a resin solid component of the acrylic polymer resin emulsion. A compounding amount of the alcohol is within a range of 25 to 150 wt % with respect to the chromium ion. An amount of the resin film is within a range of 0.5 to 3.0 g/m2, and a content of chromium ion in the resin film is within a range of 5 to 50 mg/m2.

摘要:
The present invention relates to a heat dissipation unit for cross flow type cooling tower with which it is possible to prevent the emission of white vapor without lowering the cooling power of the cooling tower, and also without requiring troublesome routine operation. In order to accomplish the above object, the heat dissipation unit of the present invention comprises filling plates arranged vertically and parallel with each other so as to form spaces therebetween, each of the filling plates having uneven surfaces down which water to be cooled flows when water to be cooled is supplied onto the filling plates, and cowl members disposed between neighboring filling plates, each of the cowl members including a pair of side plate portions having upper ends and a roof portion connecting the upper ends of the side plate portions. The side plate portions of the cowl members are arranged substantially parallel with the filling plates so as to form gaps between the filling plates and the side plate portions of the cowl members.
摘要:
Hot water is sprayed to fillers arranged immediately under a hot water vessel through spray ports opened on a lower surface of the hot water vessel. The hot water flowing down along the fillers is cooled through direct contact with ambient air. The cooling tower includes fillers partitioned alternately into permanent wet and wet-dry changeover regions which are mutually isolated for flow passages of the ambient air and spray pipes provided on the lower surface of the hot water vessel exclusively for the wet-dry changeover regions such that the hot water can be sprayed to the wet-dry changeover regions separately from the permanent wet regions. The hot water vessel is supported by the spray pipes. The spray ports of the hot water vessel is communicated only with the permanent wet regions.
