IPC: H05K3/34
Filed: 1989-04-05
Abstract: PURPOSE:To prevent the oxidation of a solder melt by forming through-holes through which the solder melt in a receiving/preserving tank flows from the bottom of the receiving/preserving tank down onto the liquid surface of the solder melt after the jet solder and overflow solder from a 2nd gushing tank is received and preserved in the receiving/preserving tank. CONSTITUTION:A 1st gushing tank 13 and 2nd gushing tank 14 which pressurize the solder melt 12 by pressurizing means and forcibly eject the melt are arrayed in a solder tank 11. The solder melt is ejected backward from the traveling direction of a printed circuit board 1 to the gushing port 21 of the 2nd gushing tank to form the jet solder. A tray 24 to form the overflow solder 12c formed by allowing the solder melt 12 to flow over an adjustable weir plate 26 to the traveling direction of the printed circuit board mentioned above is provided. The receiving/preserving tank 27 which receives and preserves the jet solder and the overflow solder is provided below the gushing port edge 21a on the jet solder side of the 2nd gushing tank and the tray 24 side.

Inventor: KONDO KAZUMITSU
IPC: B22C3/00
Filed: 1993-04-12
Abstract: PURPOSE:To form the uniform releasing film which is not repelled even when the oil remains on the surface of a mold by consisting of strong basic amine and higher fatty acid and/or ethylene glycol as essential components, diluting the stock solution with water to an appropriate viscosity and using it in the form of aqueous solution. CONSTITUTION:The stock solution of the releasant constitutes of strong basic amine such as morpholine and higher fatty acid such as oleic acid and/or ethylene glycol or the like as essential components and is regulated through mixing and adding. When the stock solution is coated on the surface of a model for molding the green sand mold, it is diluted to an appropriate viscosity to be used as the releasant. Because the stuck solution of the releasant can be diluted with water, it is not bulky in storing or carrying, and the storage and carriage is facilitated. In the composition of the releasant when it is coated, no oil of hydrocarbon based is used, and the resouries saving and fire safety are improoved. A uniform releasing film can be formed on the surface of the mold, and the releasant can be coated in the form of the aqueous solution. The leakage resistance for the mold when used as the releasant can be improved.

Title: Dc power supply circuit with trolley wire
Inventor: WATARI TATSU
IPC: H02J1/00
Filed: 1993-04-13
Abstract: PURPOSE:To supply power with high reliability to supply power from trolley wires to a load by connecting a unit having charging/dicharging functions at a voltage extremely near to a power source voltage in parallel with the load. CONSTITUTION:DC power is supplied to a load 4 by connecting brushes 2-1, 2-2 to a load 4 and bringing the brushes 2-1, 2-2 into contact with trolley wires 1-1, 1-2. When a battery 5 which can be charged is connected in parallel with the load between the brushes 2-1 and 2-2, a voltage of the battery 5 is so set as to be charged to a slightly lower voltage than the voltage applied between the wires 1-1 and 1-2. Accordingly, since the voltage to be applied to an impedance of the load 4 is substantially equal to the voltage of the battery 5, the voltage to be applied to the impedance of a loose contact part at the time of loose contact becomes substantially zero to be scarcely discharged. As a result, even if the loose contact occurs, the discharge is scarcely generated to supply power with high reliability.
