Title: Fluidized-bed boiler
Inventor: TAKAGAWA HIROHITO
IPC: F22B1/02
Filed: 1988-10-04
Abstract: PURPOSE:To prevent the formation of clinker and supply steam under a stabilized steaming condition (in temperature, pressure, and amount of vaporization) by providing a device for ejecting air or exhaust gas to level down heaps overlying a resting fluidized bed and scatter them over a heat exchanger tube and at a level below the height of a stationary bed of fluidization medium. CONSTITUTION:Since inert gas, such as air or discharged combustion gas, is intermittently ejected from tubular diffusers 7, a layer of heaps is leveled down with part of the heaps displaced into a fluidized bed 4 so that the bed in the furnace as a whole is leveled out with an effect to prevent the fluidized bed 4 from falling in height. The formation of clinker is also prevented, since the formation of hot spots due to stationary combustion of fragments of coal 8 scattered on a fixed bed 5 can be prevented. Furthermore, since tubular diffusers 7 are disposed above a heat exchanger tube 3, the layer of heaps can be leveled down without fluidizing the medium in the layer around the heat exchanger tube 3. Therefore, even when the layer of heaps 9 is leveled down by blowing air from the tubular diffusers 7 into the layer of heaps 9, heat absorption by the heat exchanger tube inside the fixed bed 5 does not take place so that even at a time of partial loading, steam can be supplied under stabilized conditions of temperature, pressure, and amount of vaporization.

Title: Equipment for heating and evaporating slurry
Inventor: TSUJINO TOSHIO
IPC: C10L1/32
Filed: 1990-09-20
Abstract: PURPOSE:To prevent the deposition of dried slurry on the wall of a heat transfer tube to thereby make it possible to heat and evaporate slurry efficiently by a constitution wherein carrier gas flows into the heat transfer tube through a space between the outside of a supply tube and the inside of a heat transfer tube. CONSTITUTION:In equipment for heating and evaporating slurry, the slurry is fed through an introduction port 15 into a slurry introduction chamber 3, passes through a slurry supply tube 26, and flows into a heat transfer tube 20. On the other hand, carrier gas is introduced from an introduction port 11 into a carrier gas introduction chamber 2 and flows into the heat transfer tube 20. Because of a constitution wherein the carrier gas flows into the tube 20 through a space between the inside of the tube 20 and the outside of the tube 26, a carrier gas layer is formed along the inside of the tube 20 so that the slurry will be heated and evaporated without direct contact with the inside thereof by the heat of high temperature fluid transferred through the wall of the tube 20. The generated steam and granules go into a steam withdrawal chamber 4 and are then withdrawn from a withdrawal port 18. Because the slurry does not come into direct contact with the inside of the tube 20, the dried slurry will not deposit thereon, so that efficient heating and evaporation can be accomplished.

Title: Reduced projection-exposure device
Inventor: MATSUKAWA HISAHIRO
IPC: H01L21/30
Filed: 1987-10-05
Abstract: PURPOSE:To conduct a reduced projection-exposure operation with which a pattern can be transferred in a highly precise manner by a method wherein the local inclination of the surface of a wafer is accurately detected without narrowing the width of a laser beam narrower than the width of a scribe line. CONSTITUTION:After a wafer 6 has been moved to the prescribed position by an ordinary positioning mechanism, the inclination of the exposing region such as the wafer surface of one-chip component is detected by a detecting part 8. Then, at least either of a reticle 4 and a wafer stage is inclined so that the above-mentioned inclination can be corrected. In this case, when the wafer stage only is inclined, the wafer stage is inclined by a stage fine adjust ment part 7 in the amount same as the detected inclination. Also, when the reticle only is inclined, the reticle 4 is inclined five times of the wafer surface detected by the reticle fine adjusting part 5 in the case of 1/5 contraction, for example. Accordingly, a transfer operation can be conducted on the wafer surface in a highly precise manner by performing the correction of inclination on the exposing region in advance.

Abstract: PURPOSE:To realize the suitable directional solidification and to manufacture a casting product of uniform quality by repeating casting while selectively supplying the cooling water or the pressurized air into a through hole arranged at the lower part of a metallic mold to form the optimum temp. gradient in the metallic mold. CONSTITUTION:By allowing the cooling water to flow in the penetrated hole 4 formed at the lower part of metallic mold 1, the lower part is forcedly cooled, and while suitably holding the directivity of solidification of the molten metal in the cavity 2, the casting is executed. In this constitution, at the time of taking out a solidified work, when the temp. of the metallic mold 1 falls to the prescribed temp. or lower, by closing a valve 9 with control unit 10, supply of the cooling water is stopped. At the same time, by opening a valve 7, the pressurized air is blown into the penetrated hole 4 from a compressor 12 to quickly discharge the remaining cooling water in the penetrated hole 4. When the detected value with a thermometer 5 in the metallic mold 5 comes to the prescribed value, the molten metal is again poured into the cavity 2, and at the same time, supply of the cooling water into the penetrated hole 9 is restarted. By this method, the metallic mold can be kept to the desirable temp. condition and the product having uniform quality can be continuously cast.
