Filed: 1993-07-22
Abstract: PURPOSE:To increase a bore to increase capacity of a storage tank, namely to perform the reliable increase of the diameter of a tank roof without increasing construction cost. CONSTITUTION:A roof structure 1 forms a hybrid type constituted such that two kinds of roof materials are combined together to increase the bore (increase of diameter) of a storage tank 2 for low temperature liquefied gas. Namely, a roof body part 4, being the central part of a roof, of an underground type tank 2 is constituted by using a material made of a steel, such as a roof beam and a roof plate, to hold an economical span (diameter) hereafter employed. Further, simultaneously, to increase the bore of the tank, an overhang roof part 3 built integrally with a side wall 2a is built to the top part of the side wall. The two roof materials for a roof body part 4 and an overhang roof part 3 form an integral roof structure at a point of time when construction is completed, and high capacity storage is practicable.

Title: Semiconductor device and manufacture thereof
Inventor: OTSUKA REI
IPC: H01L23/52
Filed: 1989-07-12
Abstract: PURPOSE:To manufacture a semiconductor device having a simple structure at a high yield through a small number of manufacturing processes by providing a plurality of silicon films of non-single crystals at specific positions and making the film on one side to contain more hydrogen elements. CONSTITUTION:After forming a Cr metal layer 2 by sputtering, the layer 2 is selectively etched. Then the layer 2 is successively coated with SiNx layer 3, a-Si layer 4 containing little impurities, snd SiNx layer 5 of specific concentrations. The layer 5 contains more hydrogen than the layer 3 does and the layer 3 is composed principally of a high-melting point metal containing a nonmetallic element between a silicon film of non-single crystals and wiring. In addition, the layer 5 is formed between the layer 3 and the above-mentioned silicon film of non-single crystals. When such structure is used, the problem of stripping off can be eliminated, since no n<+> a-Si film is formed, and the number of manufacturing processes can be reduced while the ohmic property is maintained in the connection between the layer 4 and metallic wiring. Therefore, the yield can be improved and wiring resistance can be reduced.
