Filed: 1988-06-17
Abstract: PURPOSE:To prevent an air bent section from being clogged with a filler by forming tapers or curved surfaces on upper and lower opposite edges of an inside cross section of the air bent section, and mounting an electric parts element on the same and molding the same with resin. CONSTITUTION:Upper and lower edges of an air bent section 1e positioned inside the same are tapered, the air bent section 1e being located between dotted lines 21, 22 and constituting part of a lead frame 1 fraction provided along a side of a resin-sealed section 20 of the lead frame 1, the side being located opposite to the resin injection side.

Title: Method for manufacturing square chip resistor
Inventor: HASHIMOTO MASATO
IPC: H01C7/00
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To prevent rear surface electrode layers of a square chip resistor from sticking together in an electrolytic plating process, by allowing an end surface electrode layer to infiltrate into the rear surface electrode layer side for forming the rear surface electrode layer at the same time when an end surface electrode layer is formed. SOLUTION: A square chip resistor comprises a substrate 1, an upper surface electrode layer 2, a rear surface electrode layer 8, an end surface electrode layer 3, a resistor layer 4, and an over-coat glass layer 5 which covers the resistor layer 4. When the chip is manufactured, a thick-film silver paste is coated so as to overlap with a part of the upper surface electrode 2 and a part of the rear surface electrode layer 8 on an end surface of a strip-like substrate, so that an electrode layer on a rear surface side may be thick. Then the chip is sintered to simultaneously form the end surface electrode 3 and the rear surface electrode layer 8.  Then the strip-like alumina substrate is divided into solid pieces, and an Ni plating layer 6 and an Sn-Pb plating layer 7 are formed on exposed upper surface electrode layer 2, end surface electrode layer 3, and rear surface electrode layer 8 by electrolytic plating. Thus, a sticking-defect rate in electrolytic plating process is decreased.

Title: Infiltration treatment of borocarbide -, boron- and boride-reactive metal thermet
Inventor: DANII SHII HARUBUAASON
IPC: C04B41/88
Filed: 1987-06-17
Abstract: A chemical pretreatment method is used to produce boron carbide-, boron-, and boride-reactive metal composites by an infiltration process. The boron carbide or other starting constituents, in powder form, are immersed in various alcohols, or other chemical agents, to change the surface chemistry of the starting constituents. The chemically treated starting constituents are consolidated into a porous ceramic precursor which is then infiltrated by molten aluminum or other metal by heating to wetting conditions. Chemical treatment of the starting constituents allows infiltration to full density. The infiltrated precursor is further heat treated to produce a tailorable microstructure. The process at low cost produces composites with improved characteristics, including increased toughness and strength.
