Title: Soldering device for printed circuit board
Inventor: SAITOU TAKATSUGU
IPC: B23K1/08
Filed: 1983-09-27
Abstract: PURPOSE:To solder uniformly electrical parts on a circuit board and to solder satisfactorily long-leg electrical parts as well with a titled device which generates foam in molten solder by providing a transverse oscillating net plate which allows passage of the foam to said device. CONSTITUTION:Gaseous N2 or the like is ejected from a nozzle 5 in the bottom of a solder tank 3 into the molten solder 4 in the tank 3 to generate foam 6. The foam 6 tries to move upward to the surface of the solder 4 but a net plate 7 which oscillates transversely in the solder 4 above the nozzle 5 is installed and therefore the foam passes through the plate. The foam 6 in this stage is cut transversely by the plate 7 and is segmented to foam 8 which ascends. Even if the foam 8 sticks to each other before the foam 8 arrives at the surface of the solder 4, a fairly long distance is required for the foam to grow to the size of the foam 6 and therefore even if the distance between the plate 7 and the surface of the solder 4 is taken at the height necessary for soldering of long-leg electrical parts, the foam is smaller than the foam 6. The build-up by the foam 8 on the surface of the solder 4 is thus approximately uniform and satisfactorily soldering is accomplished with a printed circuit board 1 and leadless electrical parts 2.

Title: Manufacture of hollow inorganic molding
Inventor: MIURA KENJI
IPC: B28B3/02
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To prevent a rupture of a base material from generating due to steam in a drying process by surface pressing a hollow inorganic molding so that a hollow part remains at least in a specific sectional area. SOLUTION: After a hollow mineral molding 1 having a hollow part 2 therein is molded, the molding 1 is surface pressed to form a pattern. In this case, the molding 1 is surface pressed so that the part 2 collapsed at the time of surface pressing remains open in a sectional area of at least 0.2 mm2. Here, a flowability is imparted to the molding 1 by alleviating a depth of the pattern such as a joint part or the like formed by altering a pressing amount at the time of surface pressing or vibrating a general material using a material having flowability, thereby regulating it by surface pressing or the like. A material, its mixing, moisture amount and the like to form the part 2 by molding are suitably selected.  Thus, the part 2 is not closed even by forming the pattern after molding, a pressure rise of the part 2 according to the steam generated at the time of heating to dry is suppressed to a base material strength or less, thereby preventing the occurrence of a rupture of the base material.
