Title: Fabrication of semiconductor device
Inventor: KITAHARA KUNINORI
IPC: H01L27/12
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To increase the crystal grain size by irradiating a deposition layer on a substrate with laser light exhibiting higher absorbance to the deposition layer 11 than the substrate 1 while increasing or decreasing the intensity of light gradually and heating the deposition layer at higher temperature than the substrate thereby lowering the cooling rate of the crystal easily after extinction of the laser. SOLUTION: SiO2 2 is deposited on a substrate land a-Si 11 is deposited thereon. The a-Si 11 is then irradiated with laser light 4 and crystalized thus transforming the a-Si 11 into p-Si 12. Subsequently, the substrate is transferred to an lamp annealing chamber. In the lamp annealing chamber, linear halogen lamps 21 are arranged at constant interval with a reflector 22 being disposed on the back of each lamp and the irradiation is performed from the Si layer 12 side while feeding nitrogen gas. The deposition layer 11 is irradiated with a light exhibiting higher absorbance to the deposition layer 11 than the substrate 1 while increasing or decreasing the intensity of light gradually and then the deposition layer is heated at higher temperature than the substrate 1 thus crystalizing the deposition layer 11.

Title: Carrier for electrophotography
Inventor: IKEDA TAKESHI
IPC: G03G9/113
Filed: 1988-12-19
Abstract: PURPOSE:To decrease spenting of a toner and to prevent charge up by coating the carrier with an acrylic resin dispersed with graphite having 0.1 to 0.5mum grain size. CONSTITUTION:The carrier is coated with the acrylic resin dispersed with the graphite powder having 0.1 to 5.0mum grain size. Since the graphite is flaky, extremely slippery and highly conductive, the graphite acts effectively on spenting of the toner in the acrylic resin-coated carrier. Namely the flake graphite exists on the surface and, therefore, the adhesion of the toner is prevented by the slipperiness thereof. In addition, the graphite is the flaky state of high cleavage and, therefore, even if the toner is adhered and spent, the toner is easily peeled and always the fresh surface is exposed. The charge is hardly accumulated on the carrier surface because of the electrical conductivity and the peeling of the toner from the carrier is accelerated.

Title: Continuous annealing and continuous carburizing of metal strip
Inventor: NAKAGAWA FUTAHIKO
IPC: C21D1/26
Filed: 1992-11-27
Abstract: PURPOSE:To provide continuous annealing and carburizing method in which, like a high baking hardening type (low Al-high BH) steel plate, etc., having normal temp. slow aging, a carburizing concentration in a surface layer part increases larger as a carbon concentration in an inner layer part remains low and which is suitable for much distributing a solid solution C affecting BH in a crystal grain boundary while a solid solution C is little in a crystal grain related to Al in the surface layer carburizing part. CONSTITUTION:After subjecting to annealing under strip temp. condition above the recrystallization temp. for the strip consisting of a very low carbon steel, etc., passing to a continuous annealing and carburizing apparatus, carburization is applied at the strip temp. lower than the recrystallization temp. to reduce moving of a grain boundary, and diffusion of a solid solution C to an inner layer part is suppressed to increase the concentration of the solution C only in a surface layer part, and at the same time, taking in of the solid solution C into a grain is suppressed to make much the solid solution C exist in the grain. Also, the cooling rate after the annealing is suppressed to control a take-in quantity of the solid solution C into the grain, and cooling resulting temp. before carburization can be controlled and, as a result variance in a carburizing concentration on the strip width direction is suppressed.

Title: Heat emitting body of fe-cr-al series alloy with excellent electric insulation
Inventor: KAMIYA TSUYOSHI
IPC: C23C8/18
Filed: 1989-12-11
Abstract: PURPOSE:To ensure insulating property of an alloy of Fe-Cr-Al series without using any insulating material by forming alumina wiskers on the surface. CONSTITUTION:Alumina wisker is perfect oxide of Al and has a high dielectric resistance, exhibiting excellent insulativeness even at a high temp. Because of needle-shaped crystals stretching vertically from the surface of the parent material, it has a large apparent thickness and a high dielectric breakdown voltage, and further the growing velocity is high. Further, the alumina wisker provides tight attachment to the parent alloy and withstands severe heat shock, and its durability is excellent. The thickness of a wisker film to be formed over the surface of alloy of Fe-Cr-Al series is decided appropriately by setting the treatment time with the dielectric breakdown voltage as required. Heat emitting body consisting of this alloy with wiskers provided over the surface exhibits a high energy density and high heat emissive efficiency, and is favorable for use in a heat emitting apparatus small-sized and lightweight.
