Abstract: PURPOSE:To give strength so as to prevent the deformation due to elapsed time by forming the lower half of an eaves trough into a double wall, and by bending a side wall on the exterior side in the direction of a building, in such a way that the width of the opening between the upper half on the exterior side and the building side satisfies a certain size. CONSTITUTION:A bottom plate A provided with four strings of slit cavities 3a, 3b, 3c, 3d, an exterior side wall B which is provided with a hollow lug edge 6 on the point of the upper half B2 and which is bent in the side of a building at a stage 4, a side wall C on the building side provided with a hollow lug edge 7 on the upper end as well as a hollow expanded piece D protruded on the lower end, are provided so as to form an eaves trough. In consideration of a roof grading and rainfall intensity, the upper half B2 of the side wall B on the exterior side, is bent in the direction of the building in such a way that W0<W1, and W0=120mm are satisfied where W0 is the width of an opening and W1 is a maximum width of the eaves trough. On the other hand, b0>b1, and b0<b1+15mm are satisfied where b0 is the width of the hollow expanded piece D and b1 is the width of the lug edge 7 on the building side, so as to give strength. The deformation due to elapsed time is thus prevented, and good appearance can be retained.

Abstract: PURPOSE:To exactly perform printing without back-spacing due to printing pressure as well as raise the quality of printing by fixing a platen retracting according to the thickness of a printing medium to be set into between a printing head and the platen during the printing period. CONSTITUTION:A printer consists of a platen 23 and a printing head 22 facing the platen 23 with a spacing. The platen 23 retracts according to the thickness of a printing medium (paper) to be set into the aperture and printing is made on the medium 19. During the printing period, the upper dead point of the cam 5 pushes a cam follower 4 and turns it in the direction of arrow L, the cam follower 4 separates from a stop ball Q, and the lower part of the stop ball 2 is held at the position of the plate 23 due to the fixing of a clutch shaft 3 with a pressure plate shaft 1a by the restoring force of a torsion spring 6. Thus, the instabilization of printing due to the retraction of the platen 23 by the printing pressure of the printing wire 22a can be prevented.

Abstract: PURPOSE:To eliminate a difference in level on a peripheral circuit by a method wherein a dummy pattern which is used to reduce a difference in level between the peripheral circuit part and a memory cell array part is formed in the peripheral circuit part. CONSTITUTION:Before an interconnection process, a phosphosilicate glass(PSG) film 14 is deposited by a thickness of the difference in a height between a RAM cell array part 11 and a peripheral circuit part 12. A photoresist 15 is coated, exposed to light and developed; after that, it is etched by buffer hydrofluoric acid. Since the etching rate of a PSG is larger than that of a boro- phosphosilicate glass(BPSG) at this time, a BPSG film 13 can be utilized as an etching stopper in the RAM cell array part. Then, the resist 15 is removed; after that, an SiO2 film 16 is deposited. Thereby, the boundary part to the peripheral circuit part is made smooth and metal wiring 17 having no difference in level can be formed.
