Title: Reaction and dynamic multistage turbine downhaul motor
Inventor: EDOUARUDO BARUNETSUCHIEEGONZAR
IPC: F01D1/18
Filed: 1992-05-11
Abstract: PURPOSE: To provide a multi-stage turbine for a multi-stage turbine motor for downhaul, which operates with a fluid shear force to a turbine blade edge only or a combination of the shear force and an impact force. CONSTITUTION: A turbine comprises an external casing 3 and an internal shaft 5 disposed in the casing and rotated with respect to the longitudinal axis. A plurality of turbine assemblies 9 are provided. Each turbine assembly includes a rim 15 and a plurality of turbine blades 13 secured to the rim. A stator 11 is positioned between adjacent turbine stages. Each stator has a wall portion and a diverter portion. The wall portion is perpendicular to the axis of a shaft and the diverter portion is at an angle less than 90 deg.. In a space between the wall portions, the turbine blade and the diverter portion form a seal for obstructing the flow passing the turbine assembly. The flow between the wall portions of the stator exerts a reaction force to the turbine blade. The flow passing the diverter portion exerts dynamic force to the turbine blade.

Title: Fuel injection valve of engine and method thereof
Inventor: NOGI TOSHIJI
IPC: F02M61/18
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To improve the stability of combustion at the time of high speed by providing a fuel guide forming a plurality of fuel swirl passages having a different swirl strength, and forming the small swirl strength passage on the side of nozzle hole rather than the large one. SOLUTION: In a fuel injection valve, a fuel guide 23 is disposed around a spherical valve element 21 in a nozzle part, and a part between the element and a valve seat is opened when a movable core is pulled up at the time of energization. At this time the guide 23 forms a fuel swirl hole 33b and a fuel swirl groove 34a in parallel with virtual lines X-X, Y-Y. The offset quantity L1 of the groove 34a is made smaller than the offset quantity L2 of the hole 33b and an opening of the groove 34a is set at a lower position near the nozzle. Accordingly, the atomization of fuel with a small expanding angle formed by the groove 34a is jetted out at first, and then the atomization of fuel with a large expanding angle formed by the hole 33b is jetted out, thereby stabilizing the combustion.

Title: Reflection mirror and optical pickup
Inventor: KUME HIDEHIRO
IPC: G11B7/135
Filed: 1995-05-18
Abstract: PURPOSE: To make it possible to produce a reflection mirror in a small size at a low cost with a simple constitution and to accurately reflect light by forming reflection films and thin films having respectively the same structures on both surfaces of a nearly parallel flat plate, thereby forming the reflection mirror. CONSTITUTION: The reflection mirror 16 has the parallel flat plate 16a and the reflection film 16b for polarizing luminous fluxes formed at one surface of this flat plate and has a thin film 16c of nearly the same structure as the structure of the reflection film 16b formed on the other surface of the parallel flat plate 16a. Accordingly, the stresses on the flat plate 16a by the reflection film 16b are offset by the stresses on the flat plate 16a by the thin film 16c. Then, the stresses generated in the flat plate 16a by the change in temp. and humidity are eliminated and, therefore, the flatness on the surface of the reflection film 16b of the reflection mirror 16 is maintained in high accuracy.  Even if, therefore, the reflection mirror is constituted relatively thin, the flatness of the reflection surface is not impaired and the reflection mirror of the small size and light weight is produced at a low cost.

Title: Microwave processor
Inventor: FUJIMURA SHUZO
IPC: H01L21/205
Filed: 1987-06-10
Abstract: PURPOSE:To sufficiently excite a microwave on the surface of a workpiece and to accurately control temperature by preferable thermal conduction by composing a stage of dense alumina (aluminum oxide). CONSTITUTION:A workpiece 3 is placed in contact on a dense alumina stage 5 to irradiate it through the alumina 5 with a microwave 4 from above while controlling its temperature. That is, when a wafer 3 is irradiated with the wave 4, the wave 4 penetrates the alumina 5. Accordingly, the electric field intensity of the wave becomes large on the surface of the wafer 3. Thus, a heat treatment (or plasma treatment) is sufficiently conducted, and since the alumina 5 is relatively preferable thermal conductive, a precise temperature control (cooling) is achieved.

Title: Treatment of phosphate-contg. water
Inventor: JIYOUKOU ISAO
IPC: C02F1/58
Filed: 1981-09-14
Abstract: PURPOSE:To enable to effectively remove phosphate, by adding fluoric ion together with a Ca agent or an alkali agent to phosphate-contg. water in the presence of Mg ion. CONSTITUTION:After fluoric ion together with a Ca agent or an alkali agent is added to phosphate-contg water adjusted pH at 3-6 in the presence of Mg ion, the water is brought into contact with Ca phosphate-contg. crystal seeds (e.g. hydroxyappatite, fluoroappatite or trilime phosphate) to perform precipitation. Said fluoric ion is generally added as the aqueous solution of a water-soluble salt such as Na fluoride or K fluoride, but may be prepared by passing water through a layer packed with fluorite, cryolite or the like to dissolve fluoric ion. By the coexistence of Mg ion and fluoric ion in the phosphate-contg. water, the phosphate can be efficiently removed at a high speed while inhibiting the precipitation of impurities such as Ca carbonate even when the water exceeds a semistable zone in a case not-containing Mg ion and fluoric ion.

Title: Evaporation type heat exchanger
Inventor: MOCHIDA YOSHIO
IPC: F28D7/08

Abstract: PURPOSE:To maintain a decrease in an efficiency at a minimum limit and to prevent increases in a volume and a weight by spirally composing from all parts of a heat transfer tube in contact with medium to be cooled or a certain part thereof along cooling medium flowing direction to a part of a heat transfer tube outlet. CONSTITUTION:Cooling medium (b) fed from a cooling medium inlet 7 is fed into a straight part 11a, and the flowing mode of the medium (b) is sequentially changed via bubbling flow, slag flow and circulating flow while flowing via the part. Then, the medium (b) fed out of the part 11a is fed into a spiral tube 11b continued thereto. The flowing mode of the medium (b) flowing in the tube 11b becomes spray flow. Since droplets included in vapor flowing at the center of the tube are pressed to the inner wall face of the outer periphery of the tube 11b by the operation of a centrifugal force generated by the spiral, the droplets are directly heated through the wall of the heat transfer tube. Thus, the heat transfer characteristic of the cooling medium side of a spraying area is improved to reduce the heat transfer area of an evaporation type heat exchanger and to decrease the volume and the weight of the exchanger.
