Title: Polarization modulation semiconductor laser and its fabrication
Inventor: MIZUTANI NATSUHIKO
IPC: H01S5/00
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To simplify the fabrication process of a polarization modulation semiconductor laser having such structure as the spatial fluctuation of refractive index in a resonator due to hole burning effect is canceled in the axial direction. SOLUTION: An active layer 104 and an optical guide layer 105 are grown epitaxially on a substrate 101 and stripe grooves g1 are made therein at a predetermined period. The parallel stripe grooves are then covered with a photoresist 110 only in a partial region and the substrate is etched using the photoresist as a mask thus inverting the phase of protrusion/recess of parallel stripe grooves. The phase noninverted part is not covered with the photoresist thus etching an optical guide layer 105 thin at that part. Alternatively, the phase noninverted part may covered with the photoresist and a fourth material so that the optical guide layer 105 is not etched at that part thus making the guide layer in phase noninverted region relatively thin.

The above-mentioned masking material W has the resistance to acids and alkalis and can form the masking which is stable and sure without being dislodged from the pipe material 1 by the acid and alkalis when the pipe material is subjected to a pretreatment for plating. The binder is carbonized at 440-550 deg.C zinc hot dipping temp. The above-mentioned masking material is like soft charcoal after the end of the plating and is easily removed by a motor- operated wire brush, etc.

Title: Formation of pattern
Inventor: YAMAGISHI FUMIO
IPC: H01F41/34
Filed: 1980-02-22
Abstract: PURPOSE:To obtain a desired pattern, by lifting off two times the adjacent A and B layers by means of the third C layer. CONSTITUTION:In a bubble substrate 11 a resist pattern 13 having a thickness more than four times an A layer (SiO2)12 is formed and the A layer 12 is evaporated and a C layer (Cu, Ag etc.) 14 of lower melting point is formed thicklier than  the A layer. After the resist 13 is solved and removed, a B layer (Al etc.) 15 is  evaporated with an approximately same thickness as the A layer. With the C layer etched away, a planer structure with the A layer and the B layer closely attached  can be obtained. With such an arrangement, two kinds of planer structure can be  obtained by two times of lift-off using resist that is weaker against dry etching but  is sufficiently resistive against lift-off, and because an active ion etching is not applied to the B layer, the peel-off of the resist pattern or the reattachment of the  ions do not occur, resulting in an economical preparation.

Title: Combustor/processor for exhaust gas containing dust
Inventor: SUZUKI MINORU
IPC: F23G5/16
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To ensure long term stabilized operation while reducing the facility cost by providing a heating means for elevating the inner surface temperature of an exhaust gas duct to a melting point or above thereby avoiding trouble due to solidification of dust. SOLUTION: Exhaust gas is introduced from a duct 3 into a combustion furnace 2. Upstream part of the exhaust gas exists in an inner pipe 24 and heated by heating gas from a heating gas supply pipe 29 through the inner pipe 24. Downstream part of the exhaust gas reaches an outer pipe 23 while being melted thence reaches a molten dust discharge opening 25 at the downstream end before being dropped and taken out from a molten dust take-out opening 26. Periphery of the molten dust discharge opening 25 and the molten dust take-out opening 26 are heated by the flame of heating burner 27 and molten dust is not cooled down to be solidified. Molten dust flowing down on the inner wall of the outer pipe 23 is blocked by a dam part 28 and it is not fed to the combustion furnace 2 but introduced to the molten dust discharge opening 25.  Consequently, exhaust gas is introduced into the combustion furnace 2 under a state where dust is melted and removed substantially entirely.
