Title: Air conditioning system for railway rolling stock
Inventor: GOTOU MIKI
IPC: B60H1/00
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To provide an air-conditioning system for railway rolling stock which does not generate a draught and the like, and can carry out the air conditioning sufficiently while giving a comfortable feeling to passengers. SOLUTION: The air in a car room 2a is sucked from suction ports 24, 40, 52, 54, and the like existing almost at a ceiling 18 part, flows through exhaust passages 22 and exhaust pipes 62 and 64, and reaches to an air-conditioning device 60. After the air is temperature regulated in the air-conditioning device 60, it is delivered therefrom to a ventilation trunk 16 as a conditioned air, and blown off in the car room 2a from blowoff ports 15 and the like existing on the upper floor 4a.  Consequently, since the conditioned air is filled in the car room 2a from the lower side, while pushing up the air in the car room 2a, the passengers can be surrounded by the comfortable conditioned air rapidly, and since the conditioned air reaches to the passengers directly while existing no hindering air on the way, it is not necessary to blow off the air strongly from the blowoff ports 15 and the like, and no draught is generated.

Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To reduce operation current and to prolong the life of an element by reducing a waveguide loss due to the adsorption of light from an active layer by an etching stop layer. SOLUTION: In an embedded ridge type AlGaInP semiconductor laser where an etching stop layer being made of GaInP is introduced for forming a light waveguide, Zn is introduced in a p-type GaInP etching stop layer 7 as a p-type impurity, the impurity concentration of the p-type GaInP etching stop layer 7 is set, so that the band gap of the p-type GaInP etching stop layer 7 reaches a desired value by considering the increase effect of the band gap, due to the cancellation of the natural ultra lattice of GaInP due to the introduction of Zn and the decrease effect of the band gap due to the induction of a tail state at the band end of GaInP by introducing Zn. More specifically, by considering the off-angle of the p-type GaInP etching stop layer 7, the concentration of Zn to be introduced to the p-type GaInP etching stop layer 7 is set, so that the band gap of the p-type GaInP etching stop layer 7 can be made as large possible.
