Title: Manufacture of semiconductor laser
Inventor: NARUI HIRONOBU
IPC: H01S5/12
Filed: 1990-08-30
Abstract: PURPOSE:To obtain a DFB laser which can oscillate a required single wavelength by a method wherein a layer is epitaxially grown sequentially on the main face of a semiconductor substrate on which a stripe-shaped mesa protrusion has been formed along a direction at a prescribed angle to the <011> crystal-axis direction and a diffraction grating is formed on the side face of the epitaxial growth layer. CONSTITUTION:A semiconductor substrate 1 on which a stripe-shaped mesa protrusion 2 has been formed along a direction at an angle theta (where 0 deg.<theta<45 deg.) to the <011> crystal-axis direction and which is provided with a (100) crystal plane is prepared. A stripe-shaped epitaxial growth layer 30 is formed sequentially on its main face 1A. At this time, when the stripe- shaped epitaxial growth layer 30 is formed by an ordinary MOCVD method, i.e. by an MOCVD method by using a methyl-based organic metal as a raw-material gas, a direction in which the stripe-shaped mesa protrusion 2 is extended is tilted at theta deg. from the <011> crystal-axis direction. As a result, when a (111) B crystal plane is produced almost spontaneously, a slope 10 composed of the (111) B crystal plane is formed to be a step shape or a sawtooth shape. Consequent by, an active layer 4 is provided with the side face in the step shape or the sawtooth shape; a diffraction grating 13 is formed; the pitch of the diffraction grating 13 is controlled by changing the angle theta from the <011> crystal-axis direction of the stripe- shaped mesa protrusion 2.

Title: Fluidized bed type combustion device
Inventor: KAWAMURA YOSHIO
IPC: F23C10/18
Filed: 1982-12-24
Abstract: PURPOSE:To improve the separation between agglomerate matters and a fluid medium while preventing discharge of the fluid medium associated with the discharge of the agglomerate matters on a fluidizing air passing through a clearance at a high speed by arranging a water cooling tube above an air feed tube to lengthen the distance of the clearance between the air feed tube to lengthen the distance of the clearance between the air feed tube and the water cooling tube. CONSTITUTION:A fluidized bed type combustion device 1 has a fluidizing unit comprising an air feed tube 2 and a water cooling tube 4 arranged thereabove 2. The air feed tube 2 has an air jetting port 3 so opened as to prevent infiltration of a fluid medium 5 thereinto 2 and a gas jetted from the air jetting port 3 passes through a clearance of the air feed tube 2 to fluidize the ambient fluid medium 5. But as air runs at a relatively fast flow velocity through the clearance of the air feed tube 2, easy to fluidize is pushed up to an upper layer so that hard to fluidize large particles alone can exist in the clearance. This allows the discharge of agglomerate particles by opening a discharge port 6 of the fluid medium when the accumulation of the agglomerate particles increases but minimizing the possibility of discharging the easy to fluidize medium simultaneously.
