Title: Metal mask for solder paste printing
Inventor: NAKAHARA TERUMI
IPC: H05K3/34
Filed: 1988-07-01
Abstract: PURPOSE:To prevent the occurrence of drooping and a solder bridge after a solder paste is printed, by specifying diameters of ports on the injection side and the other side of a through hole so formed in a metal mask as to correspond to a wiring pattern position, and a diameter between the two ports. CONSTITUTION:In a part of a metal mask 1, openings 3 and 4 are formed at positions corresponding to wiring patterns 2 formed on a printed circuit board P. The diameters of ports 5 and 6 of the openings 3 and 4 on the squeeze side, i.e. on the side whereon a solder paste is injected, are formed to be (a) and (b) respectively, while the diameters of ports 7 and 8 thereof on the printed circuit board side are formed to be (c) and (d) respectively, and a construction is made so that the diameters (c) and (d) are about 1.5 times larger than the diameters (a) and (b) respectively. When the metal mask 1 thus constructed is superposed on the printed circuit board P and the solder paste is printed, solder pastes 9 are printed in the shape of a trapezoid. In the printed solder pastes 9, the occurrence of drooping and a solder bridge is reduced. On the occasion when the metal mask 1 is removed from the printed circuit board P after the solder paste is printed, in addition, the metal mask 1 can be detached excellently from the board.

Title: Burning method for furnace
Inventor: KATAYAMA YUKUO
IPC: F23C99/00
Filed: 1995-06-06
Abstract: PURPOSE: To efficiently desulfurize at a low cost by spraying a slurry-like desulfurizing agent containing an alkaline metal or alkaline earth metal to a combustion flame at a predetermined speed or more in a combustion furnace. CONSTITUTION: A slurry-like desulfurizing agent of mixing comminuted Ca(OH)2 corresponding to 40% of water weight with water corresponding to 20% of fuel oil weight is sprayed in combustion flame of fuel oil C of 3wt.% of sulfur content at the speed near a sound speed by utilizing the volumetric expansion upon evaporation of water due to quick heating immediately before a spray nozzle outlet. Then, when the spraying speed exceeds 350m/sec, the desulfurizing rate is raised, becomes the maximum at the sound speed of 450m/sec, and is then slightly lowered. This is because, when the agent is sprayed at the speed of 350m/sec or less, the ionization of the agent and the collision frequency of fine particles do not become high, and the desulfurizing effect is not sufficiently performed.  Thus, the efficiency can be improved at a low cost as compared with the system of spraying the desulfurizing agent into a combustion furnace.

Title: Production of polyolefin resin foamed pipe
Inventor: TERAMOTO KEIGO
IPC: B29C48/355
Filed: 1995-06-06
Abstract: PURPOSE: To produce a polyolefin resin foamed pipe of which the outer peripheral surface is not damaged without generating a harmful substance. CONSTITUTION: A polyolefinic resin compsn. compounded with a crosslinking agent and an org. foaming agent is used as the molding material of a foamed pipe. This polyolefinic resin compsn. is supplied to a tube extruder 1 and the non-crosslinked foamed tubular resin 6' extruded from the tube extruder 1 is fed through a crosslinking and foaming furnace 5 while floated by hot air blown up from below to be crosslinked and foamed by this hot air to obtain a foamed pipe 6. An azo type org. foaming agent generates no harmful substance.  Since the foaming temp. of the org. foaming agent is as high as about 200 deg.C, it is necessary to pass the non-crosslinked unfoamed tubular resin through the crosslinking and foaming furnace but, since the tubular resin is fed through the crosslinking and foaming furnace in a floated state, the tubular resin is not deformed like a case fed by a conveyor and can be uniformly foamed.

Title: Continuous hot dip metal coating method and continuous hot-dipping device
Inventor: GOMI SHUJI
IPC: C23C2/14
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To effectively execute the prevention of floating material on bath surface without damaging the workability and the productivity by plating while shifting the dipping position of a steel band into the base surface in a snout to the position near the outlet side of the steel band from the center position of the snout at the time of regular plating. SOLUTION: At the time of regular plating, the dipping position of the steel band 1 into the plating bath is shifted to the outlet side of the steel band 1 regarding the inner wall of the snout 4 from the center position 10 of the snout and it is plated. By this method, the sticking of dross to the steel band 1 in the snout 4 can be prevented by reducing the dross invaded in the snout 4 along a sink roll 6. The larger the shifting quantity of the dipping position of the steel band 1 is, the less the dross invaded in the snout 4 is.  Therefore, this position is desirable to shift by the bath surface width (the inlet and outlet side direction distance) from the center on the plating bath surface in the snout, i.e., by >=1/4 of the snout thickness, but in the case the steel band 1 approaches too near the inner wall of the snout, since it is fear to develop scratched flaw with the piled dross on the bath surface, the interval with the inner wall of the snout is desirable to be >=30 mm.
