Title: End face light emitting diode and manufacture thereof
Inventor: WATANABE HIDEAKI
IPC: H01L33/30
Filed: 1989-12-22
Abstract: PURPOSE:To enhance a light emitting diode in light emission power by a method wherein a part of a current blocking layer confronting a light emitting end face is cut out, a light emitting layer is formed partially penetrating into the cutout thus made, and a current path is formed in a part which confronts the light emitting end face. CONSTITUTION:When a forward bias is given to electrodes 7 and 8 of a light emitting diode, a current is injected only into a part of a current path 2A where a current blocking layer is not formed, as a result, only a part of an active layer 4 above the current path 2A serves as a light emitting section. Therefore, as shown by a chain line C, emitted light rays are projected outside from this end face. The lateral and the longitudinal shape of the emitted light are determined basing on the width of the current path 2A and the sum of the active layer 4 and clad layers 3 and 5 which sandwich the active layer 4 between them respectively, so that the emitted light becomes a fine slit light. As mentioned above, a current is concentrated on an end face and a part surrounding it, so that a low current region where no thermal saturation occurs is high in light emission power.

Title: Manufacture of titanium or titanium alloy welding pipe
Inventor: MIYAMOTO ATSUYUKI
IPC: B23K28/02
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To perform a high-speed pipe manufacturing while keeping a sound welding condition by melting a pipe to the pipe inner face with plasma arc at an electrode at the tip to form an inner face bead, and forming a molten pool which does not reach the pipe inner face with low energy arc at the following electrode to perform the shape correction of a surface bead. SOLUTION: When a plasma electrode with a high welding performance is used for a preceding electrode, a problem that an undercut A formed on a preceding bead surface becomes significant can not be avoided. Therefore, a molten pool P with a crown-like cross sectional shape is formed, and a degree of the undercut A becomes significant as the thickness of the pipe gets bigger. Then, a plasma arc is used as a following electrode for melting a bend outer face only, without penetrating to the inner face side, so as to smoothen the outer face bead by correcting the undercut A formed to the preceding bead. Thereby, the following correction welding or grinding become unnecessary. And even in case of a titanium or titanium alloy welding pipe, a pipe can be manufactured at high speed without generating micro cracks.

Abstract: PURPOSE:To prevent the deterioration of CO oxidation catalyst by a decrease in the concn. of CO by continuously analyzing the concn. of CO in an exhaust gas before the oxidation of CO and adjusting the grain sizes of powder coke in such a manner that the concn. of CO attains a prescribed value. CONSTITUTION:The exhaust gas from a sintering machine 1 in a sintering plant is desulfurized by a desulfurization reactor 2 and is preheated by a heat exchanger 3. The gas is further heated by a heater 5 and is denitrified in a denitrification reactor 6. The exhaust gas after the denitrification is introduced into CO oxidation catalyst device 7 where CO is oxidized. The exhaust gas increased in temp. is sent to the heat exchanger 3 and is used as a heat source for heating the exhaust gas after the desulfurization. The concn. of CO in the exhaust gas is continuously analyzed before the oxidation catalyst device 7 of this treating system for the sintering exhaust gas. The supply rate of coke to a granular coke crushing system is changed to lower the grain size thereof until the grain size of the power coke in the sintering ore raw materials attains a prescribed average grain size when the concn. of CO falls below the prescribed value. The charging quantity of the powder coke may be decreased without adjusting the grain size of the powder coke if the concn. of CO is higher than the prescribed value.
