Title: Control method for water wheel operation
Inventor: KIMOTO YUTAKA
IPC: F03B15/02
Filed: 1985-06-05
Abstract: PURPOSE:To prevent the occurrence of cavitation easily and surely by reducing effective head through the generation of a water flow loss with the inlet valve of a hydraulic pressure pipe closed slightly, when water wheel operation is controlled in a large head and low flow volume area. CONSTITUTION:A hydraulic power plant is equipped with a water wheel 1, a hydraulic pipe 2 and an inlet valve 3. Effective head working on the water wheel of such a hydraulic power plant is given as H=UWL-TWL-DELTAHL, where H=effective head, UWL=upper water level, TWL=lower water level and DELTAHL=water flow loss. In this case, the water flow loss AHL increases in proportion to the square of a water flow. Consequently, DELTAHL decreases in a small flow volume area and the effective head H gives an increase. In order to cope therewith, a water flow loss is generated with the inlet valve 2 of the hydraulic pipe 3 closed slightly rather than wide opening for the operation of the plant in an area of small flow volume and large head, thereby causing the drop of the effective head. Therefore, the occurrence of cavitation can be prevented.

Abstract: PURPOSE:To efficiently transmit the heat generated by secondary combustion to a metal bath by burning a carbonaceous material by gaseous O2 so that ore is reduced by melting and splashing the formed metal as splashes to a secondary combustion zone by a gas contg. ore powder. CONSTITUTION:The carbonaceous material and ore are charged into the furnace 1 of the melt reduction furnace. On the other hand, the gaseous O2 is blown from bottom blowing tuyeres 6, etc., into the furnace to burn the above- mentioned carbonaceous material and to reduce the above-mentioned ore by melting, by which the metal bath 2 and slag 3 are formed. The gaseous CO formed by the combustion is secondarily burned by the gaseous O2 blown from tuyeres 4 and the metal bath 2 is heated by the heat generated by the combustion. The gaseous O2 contg. the ore powder is blown from tuyeres 5 to form splashes provided at the position at the height of the metal bath 2 in the above- mentioned operation. The metal of the metal bath 2 is easily splashed as splashes to the secondary combustion zone by the kinetic energy of the ore powder and the gas. The splashes of the metal efficiently absorb the heat generated by the secondary combustion and recover the same in the metal bath 2.

Title: Ink jet head
Inventor: MIYAZAWA YOSHINORI
IPC: B41J2/055
Filed: 1989-05-16
Abstract: PURPOSE:To improve an energy efficiency, simultaneously accomplish various characteristics, such as an ink drip delivery speed, a delivery amount, and a delivery response, and prevent a multiple delivery by a method wherein in a gap between a nozzle-forming substrate and a vibrator an area in the vicinity of a nozzle is formed larger than the other area. CONSTITUTION:The dimensional change of a Ni thin layer of a common electrode 26 is restricted because the layer has a high elasticity. When an electric field is applied to a piezoelectric element 24, the common electrode 26 generates a bending moment so as to bend toward a signal electrode 25 to be displaced by deformation. Therefore, a voltage previously applied during a standby time is selectively interrupted, whereby a free end of a vibrator 21 is displaced by deformation toward a nozzle-forming substrate 30 to allow an ink in the vicinity of a nozzle 31 to be discharged from the nozzle 31. At this time, the ink has a low viscosity of 5mPaS or less, a gap (a) between the vibrator 21 and the nozzle 31 is set to be suitable for ink drip delivery characteristics, and a gap (b) between the vibrator 21 and a part other than the vicinity of a nozzle inlet opening is set to be less than the gap (a) so that the vibrator 21 can be vibrated in an appropriate damped vibration range and an ink can be smoothly supplied.

Title: Method for preventing surface softening of aluminum alloy
Inventor: IMAMURA TSUGIO
IPC: C22F1/00
Filed: 1986-05-30
Abstract: PURPOSE:To prevent the surface softening of an Al alloy contg. Li during heat treatment by forming an oxidation inhibiting layer on the surface of the Al alloy before heat treatment. CONSTITUTION:An Al alloy contg. Li is heat treated by quenching from about 500-550 deg.C and age precipitation treatment at about 150-200 deg.C. By the heat treatment, an Li-Al compound is uniformly dispersed and precipitated, so the Al alloy can be strengthened. Before the Al alloy is heat treated, an oxidation inhibiting layer is formed on the surface of the Al alloy by anodically oxidizing the surface of the Al alloy or applying a carbon killer or the like. Thus, the surface softening of the Al alloy by the heat treatment is prevented and the Al alloy is effectively strengthened.
