Title: Ball-forming torch of bonder
Inventor: YOSHIDA KOICHI
IPC: H01L21/60
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To bring about an initially stable sparking state taking no ageing step at all, by a method, wherein a front end face of a torch is cut off making a vertical or almost vertical angle with respect to a torch axle core so as to provide a circular edge part on the front edge. SOLUTION: A torch 1 made of a round axle member is cut off at the front end thereof with an almost vertical cutting off face 1a with respect to the torch axle core, so as to form a circular edge part 2 on the front end outer periphery. Thus, since sparks are emitted from the nearest and apt to emit from position in terms of the shape thereof, thereby making feasible stable emission from a position nearer to a gold wire 4 out of the edge parts 2 on the front end of the torch 1. Accordingly, since the spark emission state is initially stabilized from the beginning the spark ageing can be dispersed with stabilizing the shape of the ball 6 also making feasible the formation of high quality stud bumps.

Title: Overlaying method
Inventor: MITSUHATA KOICHI
IPC: B23K9/04
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To provide an overlaying method which can decrease possibility that crack generated at a hard overlaying part reaches base metal fracture and can reduce progress of cracks to the base metal. SOLUTION: In this method, a high hardness metal (high carbon, high chromium) is overlaid on the surface of a base metal 3 composed of a high cracking sensitive material (high chrome cast iron). For forming a first layer covering the surface of the base metal 3, welding beads 12-15 are parallely formed on the base metal 3 surface in a manner that the adjacent beads are separated, and then welding beads 16-17 are formed between the adjacent beads in a manner to overlap both sides of the welding beads, using a welding condition which generates fine cracks to a welding bead of each pass by restraining heat input of each pass at lower than a given value. Thereby, fine and irregular cracks occur at the overlaying part, and a welding residual stress is released immediately after welding so as to prevent cracks from proceeding deeply inside the base metal.

The alloy contains approximately 58.3% gold (Au), between about 10% to about 14% silver (Ag), between about 2.5% to about 3.0% zinc (Zn), between about 0.2% to about 1.0% cobalt (Co) and the balance of the alloy being copper (Cu) with the special provision that the ratio of the weight percent amounts of copper to, the sum of the silver and two (2) times the zinc amount, ÄCu/(Ag+2Zn)Ü, has a value of between about 1.3 to about 2.5. The copper to silver weight percent ratio ÄCu/AgÜ of between about 2.0 to about 3.8, in combination with the ratio of copper to, silver + 2 x zinc, ÄCu/(Ag+2Zn)Ü results in a gold alloy with a heretofor unachievable combination of a most desirable yellow color and an exceptional degree of reversible hardness. The alloy may also contain a weight percent amount of between about 0.003 to about 0.03 iridium (Ir) which results in a gold alloy with the above characteristics but also provides for an alloy having a very fine grained structure.

Title: High speed multiplier
Inventor: NGUYEN THI N
IPC: G06F7/544
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To reduce the repeat of multiplication and also execute accelerated multiplication by comparing the cache look-up bit of a multiplicand with a preceding multiplicand. SOLUTION: A multiplier circuit 306 performs an operation about a multiplicand 302 and a multiplier 304. The multiplier 304 is designated as a constant and an output is supplied onto a line 308. When required number repeat takes place, a data effective line 310, for instance, shows a clear value such as true and when the value is detected, a result on the line 308 becomes a final product. The multiplicand is divided into a cache look-up bit(CLB) part and a table look-up bit(TLB) part. For sequential multiplicands, values are close to each other, the CLB part does not change, what is more important is that the CLB part of the product does not change and this fact enables the number of repeats which is needed to reach a final product to be reduced.
