Filed: 1988-06-06
Abstract: PURPOSE:To increase the breaking capacity by forming a flow passage to lead an insulating gas in the hollow of a driving rod to a buffer chamber, and a check valve to prevent the reverse flow at the flow passage. CONSTITUTION:When the gas flow is cut off, a movable arcing contact 7 is removed from a fixed arcing contact 4, and thereby, the pressure of the insulating gas in the hollow 5 of a driving rod 8 is raised by the heat of the arc generated between electrodes, and the insulating gas enters in a buffer chamber 9 through a thermal gas chamber 27. The insulating gas is added to the insulating gas in the buffer chaimber 9 to make the inside of the buffer chamber at a high pressure, the high pressure insulating gas is pressed by a piston 17 and sprayed to the arc, and the arc is extinguished. That is, the insulating gas pressurized at a high value by the arc energy is sprayed to the arc to extinguish the arc. Consequently, the arcing time is shortened and the arc extinguishing capacity is increased.

Abstract: PROBLEM TO BE SOLVED: To obtain a resin composition for surface mounting which is excellent in moldability and soldering resistance and reduced in void formation, by compounding an epoxy resin, a phenolic resin, a hardener, a curing accelerator, and a specific inorganic filler having a treated surface. SOLUTION: The composition comprises (A) an epoxy resin, (B) a phenolic resin hardener, (C) a curing accelerator, and (D) an inorganic filler whose surface has been treated with a surface treatment represented by the formula. The amount of the surface treatment is 0.02-5wt.% based on the whole resin composition, and at least 70% of the surface treatment has been reacted. The surface treatment is a modified silicone oil. The treated filler is produced beforehand by hydrophobizing the surface of a hydrophilic inorganic filler with the surface treatment so that at least 70% of the surface treatment reacts. Thus, the filler has improved compatibility with the resin and is evenly dispersed therein. As a result, the composition is reduced in void formation and has improved soldering resistance.

Title: Aluminum alloy plate for printing and its manufacture
Inventor: FUJIKURA CHIYOUZOU
IPC: B41N1/06
Filed: 1981-09-03
Abstract: PURPOSE:To obtain an Al alloy plate for printing giving a uniform rough surface by roughening and having superior fatigue resistance by adding specified amounts of Mg, Si and Fe to Al. CONSTITUTION:An ingot of an alloy consisting of 0.05-0.30% Mg, 0.05-0.30% Si, 0.15-0.30% Fe and the balance Al with ordinary impurities is soaked, hot rolled, cold rolled at >= about 70% reduction rate of area, and low temperature  annealed at about 150-250 deg.C for >= about 1hr. Mg is mostly solubilized in Al without exerting unfavorable influence on the roughening of the surface of the  resulting plate to enhance the strength and fatigue resistance, yet excess Mg  deteriorates the uniformity of the roughened surface in roughening. Si and Fe  form an intermetallic compound and make the crystal grains fine and uniform.  The intermetallic compound and elemental Si enhance the fatigue strength when  precipitated, yet excessive amounts of them deteriorate the uniformity of the roughened surface in roughening. Excess Si deteriorates the corrosion resistance.
