Title: Cream solder
Inventor: HARITA YASUHISA
IPC: B23K35/22
Filed: 1987-12-15
Abstract: PURPOSE:To control sagging in reflowing by using a flux contg. two kinds of rosins having different softening points. CONSTITUTION:From 40-60% low-softening point rosin having 75-105 deg.C softening point and 60-40% high-softening point rosin having 120-170 deg.C softening point are mixed to obtain a flux, and the flux is used for the cream solder. When the cream solder having such a composition is applied and reflown, the low-softening point rosin is firstly softened, however the solder powder does not flow out to the outside of the round because the amt. of the softened rosin is small. Moreover, the oxidation of the solder powder is prevented when the low-softening point rosin is softened. When the temp. is further raised, the high-temp. softening point rosin also softens, the solder powder also melts in a short time and agglomerates due to surface tension, hence the solder powder does not flow out to the outside of the round, and solder balls are not formed.

IPC: C21D9/56
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To surely prevent the meandering of a metallic sheet and to enable the improvement of quality and the high speed pass of the sheet by making liquid at the upper part of a sink roll for the metallic sheet at the inlet side into negative pressure at a liquid inner part in passing the metallic sheet through the liquid. SOLUTION: For example, a liquid flow straightening plate 6 adjoined to the metallic sheet 3 at the inlet side, is arranged and after treating by passing the metallic sheet 3 at the inlet side into the liquid 1, the sheet passing is continued as the metallic sheet 3a at the outlet side. By this method, the liquid 1 stream is formed as the arrow mark and flowed down along the straightening plate 6 between the straightening plate 6 and the metallic sheet 3 at the inlet side. By this method, the liquid at the upper part of the sink roll 5 near the metallic sheet 3 at the inlet side is made to be the negative pressure and the shaking of the metallic sheet 3 can be restrained. Further, accompanied liquid flow near the sink roll 5 by the metallic sheet 3 at the inlet side, and the rotating force of the sink roll is separated from the metallic sheet 3 at the inlet side while moving and flowing down to the liquid stream flowed down along the straightening plate 6 as the above-mentioned state, thereby the drawing of the liquid 1 into a gap between the metallic sheet 3 at the inlet side and the sink roll 5 is restrained to prevent the meandering of the metallic sheet 3.

Inventor: IWASE TERUHIKO
IPC: G09F7/00
Filed: 1993-12-16
Abstract: PURPOSE:To provide a display board which is easily producible, has an excellent design characteristic and is inexpensive. CONSTITUTION:A first colors layer 13 of a display part 20 is a continuous gradation color image formed by laminating four color separated images of yellow, magenta, cyan and black and is formed by gravure printing. A white ground layer 14 is a layer of the white ground as a concealment of the ground surface and a background of the first colored layer 13. A second colored layer 15 is the same continuous gradation image layer as the continuous gradation color image layer of the first colored layer 13. The first colored layer 13 and the second color layer 15 are matched with a deviation of <=0.3mm in image positions across the white ground layer 14. Pattern layers 16 for concealing transmitted light are pattern layers having the light shieldability for segmenting the parts to allow the passage of the light to the display part 20 and the parts which do not allow the transmission. These layers are formed by, for example, screen printing of black ink. The continuous gradation color expression with the good design characteristic, light shieldability sand definition is made possible by such constitution and the simple production stages.

Filed: 1994-12-20
Abstract: PURPOSE: To analyze a shape of filming in a contact hole with high precision in a short time by using a method which calculates only the sectional shape of the contact hole by using a two-dimensional string model. CONSTITUTION: String data are generated by connecting respective coordinate points of an outward shape line 102 obtained by cutting with a center line of the contact hole 101. Then a coordinate point 103 is extracted and a flow velocity vector 105 from a vaporization source 104 is calculated. Then the intersection 107 (Xcr, Yk, Zcr) of the straight line connecting the vaporization source 104 and coordinate point 103, and the top surface 106 (Y=Yk) of the contact hole is found and when Xcr<2> +Zcr<2> >RO<2> (RO<2> : radius of contact hole), it is considered that no flow velocity is made incident because of shadow effect. When the shadow effect is not generated movement quantity of the coordinate point is found. After calculations are made as to respective flow velocities, a coordinate point 108 after movement is selected and a calculation is repeated. After the calculations of all coordinate points end, calculations are performed in a next time step.
