Title: Production of spherical metal grain
Inventor: KATO YUTAKA
IPC: H01L21/60
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing fine spherical metal grains with superior economical efficiency because no satisfactory methods for economically producing spherical metal grains for bumps having 10 μm to 1 mm diameter have so far been provided yet. SOLUTION: Pieces of metal, obtained, e.g. by blanking a tape-shaped metal foil, rolled to prescribed thickness, with a die or cutting it into prescribed size or cutting an extra fine metal wire having <=0.1 mm diameter into prescribed size, are passed through an oxyhydrogen flame and melted in it. After being passed through the oxyhydrogen flame, the molten metal pieces are cooled and solidified, by which spherical grains having 10 μm to 1 mm diameter are obtained. A burner with a simple duplex-tube structure suffices for a burner for producing oxyhydrogen flame, and an oxyhydrogen flame is formed at the tip of the burner by supplying oxygen and the metal pieces through the inside tube and supplying hydrogen through the outside tube.  Moreover, a pressure slightly higher than atmospheric pressure suffices for the supply pressure of oxygen and hydrogen, and also the amount of oxygen and hydrogen to be supplied can be reduced to the minimam at which the burning of the oxyhydrogen flame can be continued with stability.

Title: Image sensor for radiation image
Inventor: KIRI MOTOSADA
IPC: G01T1/24
Filed: 1988-04-30
Abstract: PURPOSE:To cool down electronic circuits directly, strongly and uniformly, by providing cooling liquid flow-through conduits on the lower sides of electronic circuit parts of all radiation detecting units and by providing a porous pipe for supply of a cooling gas in a gap between the units. CONSTITUTION:Cooling water is made to flow through cooling liquid flow- through conduits 6, and a cooling gas such as air is sent under pressure into porous pies 7 for supply of the cooling gas and released into gaps from porous wall surfaces. Then a heat radiated from an electronic circuit chip 3 is transmitted excellently to a heat transfer plate 4 which the chip faces, and each electronic circuit chip 3 is cooled down uniformly substantially through the heat transfer plate 4. While the gas absorbs the heat from the electronic circuit chip 3 and gives this heat to the heat transfer plate 4, the gas itself is cooled down and supplied again for cooling down the electronic circuit chip 3. Repeating this circulation, the gas facilitates remarkably the transmission of the heat.
