Title: Semiconductor optical element structure and its etching method
Inventor: SENDA HIROAKI
IPC: H01L21/302
Filed: 1994-12-22
Abstract: PURPOSE: To obtain a clear end point detection signal when etching is to be ended, by making the thickness of an etching end point detection layer be expressed by a specified formula. CONSTITUTION: A first clad layer 52, a guide layer 53, a second clad layer 54, an etching end point detection layer 55, and a third clad layer 56 are laminated in order on a semiconductor substrate 51. The refractive index of the etching end point detection layer 55 is higher than that of the second clad layer 54 and that of the third clad layer 56. A part of the third clad layer 56 and a part of the etching end point detection layer 55 are eliminated, and a rib type waveguide is formed. The thickness of an etching end point detection layer 55 is m.λ/(2n.cosθ) where (m) is a natural number, λ is the laser wavelength for etching end point detection, (n) is the refractive index of the etching end point detection layer, and θ is the travelling angle of laser light for etching end point detection in the etching end point detection layer.  Thereby a clear end point signal can be obtained when the light whose wavelength is shorter than the absorption end wavelength of the semiconductor is used for monitoring the end point.

Title: Heat exchanger for air conditioner
Inventor: ZEN HEISAN
IPC: F24F1/0067
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To enable gathering of water totally to a receptacle of condensed water by arranging one of surfaces made up of a wave shape forming a valley part parallel with a corner to let the condensed water flow. SOLUTION: Condensed water P is formed on the surfaces of a flat fin 60 and a heat exchanger tube 22 because of a difference between the temperature of room air and the temperature of a refrigerant in the heat exchange process. The condensed water P flows down along the surface of the flat fin 60 and is gathered to a condensed water pan 40 installed at a specified distance at a lower part of the heat exchanger 20 to be drained outside. In this process, as a wave-shaped part 62 is formed in the direction of air flows on the lower end side of the flat fin 60 adjacent to a cross fan 30, when passing through the wave-shaped part 62, the condensed water P flowing down along the surface of the flat fin 60 will not be sucked in toward a cross fan 30 even by a strong air force blown from the cross fan 30 and can flow downward intact through the valley part of the wave shaped-part 62.

Abstract: PURPOSE:To prevent oxidation of molten steel caused by passing the remaining slag layer by providing weirs partitioning a molten steel receiving part from a ladle and molten steel pouring parts into molds and molten steel communicating holes at lower parts of the weirs and arranging slag communicating holes above the molten steel communicating holes. CONSTITUTION:The molten steel 12 is poured into the molten steel receiving part 16 in the weirs 4 through a short nozzle 14. The molten steel 12 is passed through the molten steel communicating holes 6 at lower part and stored into the molten steel pouring parts 18 for A strand and B strand and poured into the molds 24A, 24B through each nozzle. If the molten steel is continuously poured into the molds 24, the molten steel in the molten steel receiving part 16 and the molten steel pouring parts 18 are lowered to the same level, because there are communicated through the molten steel communicating holes 6 and the slag communicating holes 10. Further, by lowering the molten steel level, the slag 8 is caused to flow out into the molten steel pouring part 18 through the slag communicating holes 10. By this method, as the slag layer in the weirs becomes extremely thick, even if the molten metal in the second and third ladles is received this is not oxidized, and the cast slab having the target components is easily produce, and multiple sequential continuous castings can be executed.
