Title: Formation of reverse trapezoid pattern
Inventor: YANAGI YUJI
IPC: G03F7/20
Filed: 1985-03-04
Abstract: PURPOSE:To obtain a reverse trapezoid pattern of positive type photoresist with good reproducibility and steadily by a method wherein the exposure of the positive type photoresist formed on a substrate is operated by multiple exposure consisting of contact exposure and proximity exposure. CONSTITUTION:A positive type photoresist 2 is formed uniformly on a substrate 1 and dried in a furnace at about 100 deg.C. Then the substrate 1 is immersed in liquid which has an effect of curing the positive type photoresist 2, for instance monochlorbenzene, for several minutes to cure the surface of the positive type photoresist 2 to a predetermined depth. A photomask 4 is tightly contacted and ultraviolet rays are applied as shown by arrows L1. Then the photomask 4 and the cured positive type photoresist 3 are separated by a space (d) and subjected to proximity application of ultraviolet rays as shown by arrows L2. With the proximity exposure, diffractive light 5 is produced and the positive type photoresist 2 and 3 are exposed with a required angle. By development process, a reverse trapezoid pattern can be obtained.

Abstract: PURPOSE:To make it very easy to manufacture a thin window, by forming a window material in a thin membrane at a surface of a protective plate, and then processing the protective plate into a specific form of a protective frame through the etching process. CONSTITUTION:At first, a window material is pasted or vacuum evaporated on a protective plate 20 to form a thin membrane 22. Then, a photoresist layer 24 is spread and formed at the other side of the protective plate 20. After that, a masking plate 26 with cuttings responding to the radioactive beam permeable holes of the thin membrane protective frame is arranged opposite to the layer 24, and the light is radiated over the masking plate 26. When it is washed in such a condition, only exposed portions of the layer 24 remain as solid membranes 24a and the unexposed portions are removed, to expose the protective plate 20. Then, by processing the protective plate 20 in an acid solution, only the portions of the protective plate 20 covered by the solid membranes 24a remain, and the exposed portions are solved and removed. As a result, the remaining portions 20a of the protective plate 20 make the protective frame of the thin membrane 22. Thus, a thin window 30 incorporating the protective frame and the thin membranes can be easily manufactured.

In this regard, a timing circuit 15 outputs a timing signal at a designated phase point in synchronism with an output from the circuit 14. Signals corresponding to the surface profile of the sample 12 at respective bias voltages are sampled 2 by the circuit 31. The unit 26 then obtains different types of scanning tunnel microscopic image under different bias voltages substantially concurrently.

Title: Tig penetration welding method in all positions

IPC: B23K9/167
Filed: 1982-03-24
Abstract: PURPOSE:To enable penetration wleding of steel pipes of thick-walled materials easily in all butt positions, by using a high S filler wire contg. S in a specific range in automatic TIG welding. CONSTITUTION:Steel pipes of >=3mm. wall thickness are automatically TIG- welded in all butt positions by using a filler wire regulated to 0.015-0.030% S, and the content of S in weld metal is controlled to 0.012-0.025%, whereby  the permissible range of the current value at which a penetration bead of a projecting shape is formed, and the selection of welding conditions is made extremely easy. The use of the high S wire results in the decreased temp. at which the solidification of molten steel is completed, the difficulty in the flow of the molten steel in a molten pool on account of an increased viscosity of the molten steel prior to solidifying, and the possibility of formation of the penetration bead having a projecting shape in a wide current range. If the content of S is <0.012%, the effect of forming penetration is not accomplished, and if said content is excessive, the formation of a fish eye, the decrease in notch toughness, etc. arise; therefore 0.025% is an upper limit.
