Filed: 1991-04-12
Abstract: PURPOSE:To prevent the formation of solder balls caused by cream solder bleeding in a method for soldering various electronic components to a printed circuit board, for example, chip components, using cream solder and thereby prevent the degradation caused by solder balls.

IPC: B04B1/02
Filed: 1980-06-12
Abstract: PURPOSE: To recover a concentrate effectively without interruption by providing scraping members in the concentrating space or in the concentrate discharging space allowing rotation in a body with a cylindrical body, and adding a damping mechanism to these members.  
     CONSTITUTION: Scraping members 9, 10 that scrape a concentrate on the inner wall face side of a rotating cylindrical body 1 are installed in at least one of the concentrating space S 1  or the concentrate discharging space S 2  in a state that they can rotate in a body with the rotating cylindrical body 1 by the pressing force of the concentrate. A damping mechanism 11 is provided to make the members 9, 10 rotate differentially against the rotating cylindrical body 1. By this way, the concentrate flows into a passage R without causing disturbance in the concentrating space, rotates the members 9, 10 in a body with the rotating cylindrical body 1 by its pushing force, and activates the damping mechanism 11 to cause differential rotation. Thus, the concentrate is recovered effectively.

Abstract: PURPOSE:To let a forward base current and a backward base current flow corresponding to a base potential by using a bipolar transistor controlling a voltage between a collector and an emitter so as to change the polarity of the base current with the increase of a voltage between a base and the emitter. CONSTITUTION:The bipolar transistor is used while setting a voltage VCE between the collector and the emitter corresponding to the base potential under the condition of IB<IC when defining the forward base current between the base and the emitter and the backward base current between the collector and the base as IB and IC respectively. A switching element is connected to this bipolar transistor and a word line and a bit line are fitted. Therefore, by setting the voltage VCE between the collector and the emitter to a high voltage, the backward base current IC between the collector and the base larger than the forward base current IB between the base and the emitter can flow in respect to the change of a voltage VBE between the base and the emitter. Thus, the forward base current and the backward base current can flow corresponding to the base potential.

Abstract: PURPOSE: To release oxygen over a long period and to keep the oxygen concentration in water to a level above a prescribed level over a long period at a low cost without causing the pollution of water by a carrier or a binder by using a solid oxygen-generation agent composed of four specific kinds of compounds.

Abstract: PURPOSE:To prevent an Al layer from corroding for improving the moisture resistance, by making a two-layer pad electrode comprising the Al layer and a barrier metal layer. CONSTITUTION:An Al layer 3 and a barrier metal layer 4 are accumulated in this order on an insulating film 2 formed on a semiconductor substrate 1 and selectively etched by turns to form a pad electrode comprising the Al layer 3 and the barrier metal layer 4 accumulated thereon. A layer insulating film 5 is accumulated on the surface including the pad electrode and an opening is made at the center of the layer insulating film 5 on the pad electrode. An Au ball formed by shaping the end of an Au wire in spherical form is stuck by thermocompression bonding on the barrier metal layer 4 of the opening and the Au wire on the Au ball is cut off by vibrating a capillary to form a bump electrode 6. This prevents the Al layer 3 from being corroded by water intruding into the surface of the Al layer 3 and the Au ball from coming off because of a brittle alloy produced on the boundary surface between the Al layer 3 and the Au ball.
