Title: Oxygen ion conductor
Inventor: UCHIKAWA HIDEFUSA
IPC: H01M8/12
Filed: 1989-01-13
Abstract: PURPOSE:To obtain a stable and highly-conductive oxygen ion conductor by forming the conductor from a sintered body the main components of which are rare earth elements ie. Ba, Cu and O burned in a nonoxidizing atmosphere. CONSTITUTION:An oxygen ion conductor is formed from a sintered body the main components of which are rare earth elements ie. Ba, Cu and O burned in a nonoxidizing atmosphere. In order to allow active oxygen holes to exist at high density and in a stable state, the burning is performed in the nonoxidizing atmosphere. As the nonoxidizing atmosphere, an inert gas atmosphere such as N and Ar, a reduction gas atmosphere such as H, or a vacuum of 10<-2>-10<-8>Torr or so are mentioned. This sintered body has stable and high oxygen conductivity, since in its crystal structure active oxygen holes exist at high density and in a stable state.

Title: Semiconductor laser
Inventor: UENO SHINSUKE
IPC: H01S5/00
Filed: 1986-01-16
Abstract: PURPOSE:To obtain a semiconductor laser with excellent controllability and reproducibility by a method wherein the carrier diffusion length in an active layer is made shorter than the difference between the width of a region along the protruded part of the active layer and the width of a current injection region and the active layer, 2nd cladding layer and a blocking layer are pro vided adjacent to a guide layer near both reflection end surfaces of a resonator. CONSTITUTION:In a protruded region, 1st cladding layer 13, an active layer 14, 2nd cladding layer 15 and a blocking layer 16 are successively formed with uniform film thicknesses along the protruded shape. The active layer 14, the 2nd cladding layer 15 and blocking layer 16 do not reach both reflection end surfaces of a resonator and are provided adjacent to a guide layer 17 near the two reflection end surfaces. The guide layer 17 is provided over the whole length of the resonator. A current is injected into the active layer 14 through a stripe-shape window formed in the blocking layer 16 and through the 2nd cladding layer 15. In this case, as the carrier diffusion length is shorter than a half of the difference between the width of a refractive index distribution and the width of a carrier injecting region which determines the width of the gain distribution, self-exciting oscillation is promoted.
