Patent number: 6739894Abstract: A socket for an IC package avoids deformation or damage of an IC package body. The socket includes a socket body having a receptacle portion of the IC package and a plurality of contacts arranged on a bottom surface of the receptacle portion and resiliently displaceable in up and down directions. Latches are pivotably provided in the socket body and being biased toward the receptacle portion by springs. The socket further includes connecting metals provided for relative motion with respect to the socket body and for moving the latches away from the receptacle portion against the springs, slots and projections restricting motion magnitude toward the bottom surface of the receptacle portion at a predetermined value.Type: GrantFiled: May 24, 2002Date of Patent: May 25, 2004Assignee: Yamaichi Electronics Co., Ltd.Inventor: Shigeru Ogura

Patent number: 6379425Abstract: Desulfurization is carried out by blowing CaO into molten iron, and a gas mixture of an inert gas and a hydrocarbon gas is used as a carrier. The ratio of the hydrocarbon gas to the desulfurizing agent is maintained in the range of from about 2.0 to about 50 Nl/kg. This desulfurizing method improves the desulfurization efficiency of the desulfurizing agent, increases the productivity of the desulfurizing process, and reduces the amount of slag generated in the desulfurizing process. Alternatively, a desulfurizing flux is blown into the molten iron together with a carrier gas comprising a gas mixture of an inert gas and a hydrocarbon gas or an inert gas alone at the start of desulfurization. The hydrocarbon gas in the carrier gas is increased, is added, or the unit gas is replaced by the hydrocarbon gas at adequate timing, whereby the desulfurization efficiency is improved.Type: GrantFiled: June 6, 2000Date of Patent: April 30, 2002Assignee: Kawasaki Steel CoporationInventors: Naoki Kikuchi, Shuji Takeuchi, Akiharu Takao, Mototatsu Sugizawa, Shigeru Ogura

Patent number: 6328784Abstract: A process for desulfurizing a molten iron alloy in which a desulfurizing agent is applied to the molten iron alloy under agitation. Concurrently, a gas containing a hydrocarbon gas is blown onto the bath surface of the molten iron alloy, or a substance generating a hydrocarbon gas is added to the bath surface.Type: GrantFiled: June 29, 2000Date of Patent: December 11, 2001Assignee: Kawasaki CorporationInventors: Naoki Kikuchi, Shuji Takeuchi, Mototatsu Sugizawa, Shigeru Ogura

Patent number: 5429655Abstract: An apparatus for removing non-metallic foreign matter in a molten steel includes a tundish and a coil device. The tundish is an intermediate container receiving the molten steel from a ladle and feeding a purified molten steel by removing the non-metallic foreign matter in the molten steel. For removing the non-metallic foreign matter, the tundish has a swirl flow bath and a floatation bath. In the circumference of the swirl flow bath of the tundish, a coil device is arranged for flowing the molten steel in the swirl flow bath in swirl fashion. The tundish and the coil device are formed separately and constructed for relative movement to each other. The molten steel in the swirl flow bath of the tundish is flown in swirl fashion in the horizontal direction by a magnetic field generated by the coil device. At this time, the molten steel forms a parabolic concaved surface.Type: GrantFiled: November 20, 1992Date of Patent: July 4, 1995Assignee: Kawasaki Steel CorporationInventors: Shigeru Ogura, Masayuki Onishi, Hidenari Kitaoka, Mitsuru Sakurai, Toshikazu Sakuraya, Yozo Tanino, Tsukasa Terashima, Yoshiro Tomiyama, Yuki Nabeshima, Yuji Miki, Saburo Moriwaki, Noboru Yasukawa

Patent number: 5028033Abstract: A method is disclosed for accurately detecting an outflow of a slag into a stream of a molten steel when the molten steel is poured from a first vessel such as a refining furnace or a ladle into an intermediate vessel such as a ladle or a tundish through a melt-discharging hole or a nozzle. At that time, an inert gas is fed into the stream of the molten steel in the nozzle through a side portion of the melt-discharging hole or the nozzle, and the detection is made based on a change in a flow rate of the inert gas sucked into the stream of the molten steel and/or in a back pressure.Type: GrantFiled: September 7, 1989Date of Patent: July 2, 1991Assignee: Kawasaki Steel CorporationInventors: Nobuhiko Morioka, Kazuhisa Hamagami, Shigeru Ogura

Patent number: 4955126Abstract: A process for fusing a steel slab in a longitudinal direction thereof is disclosed, wherein when the steel slab is fused in the longitudinal direction at more than 500.degree. C. and at a speed of more than 300 mm/min., a surface portion of the slab including at least a lower portion of a longitudinally fused surface portion thereof is mechanically removed by cutting or grinding.Type: GrantFiled: April 20, 1989Date of Patent: September 11, 1990Assignee: Kawasaki Steel CorporationInventors: Masaru Shibata, Masayuki Onishi, Hitoshi Ohsugi, Shigeru Ogura, Masaru Washio, Hideo Kuguminato, Yoshiaki Hara

Patent number: 4432533Abstract: A method of repairing a refractory lining of a vessel lined with refractory by flame gunning process, in which a patching material consisting of refractory particles and carbonaceous fuel powder is flame-gunned together with an oxygen containing gas to fuse or semi-fuse the refractory particles in a region surrounded by high-temperature flame and struck against the surface of the refractory lining to produce a deposit layer of the refractory particles, is disclosed. In this method, a patching material having a higher mixing ratio of the fuel powder or only the fuel powder is flame-gunned at an initial stage of the repairing and subsequently patching materials, in which the mixing ratio of the fuel powder is lowered stepwise, are flame-gunned in order with the progress of the repairing, during which a blow rate of the oxygen containing gas is controlled in accordance with the change of the mixing ratio of the fuel powder in the patching material.Type: GrantFiled: April 1, 1982Date of Patent: February 21, 1984Assignee: Kawasaki Steel CorporationInventors: Masuto Shimizu, Tadashi Morimoto, Motoyasu Yaji, Masaaki Tsukamoto, Takao Suzuki, Shigeru Ogura
