Title: Injector control method for engine
Inventor: WATANABE YUKIHIRO
IPC: F02D41/20
Filed: 1985-03-18
Abstract: PURPOSE:To effectively spread a dynamic range of an injector, by detecting magnetic flux at a point of time of its almost maximum change when a valve is fully opened and switching an excitation current in an electromagnetic coil to a small current corresponding to a level holding a fully opened condition. CONSTITUTION:A fuel supply quantity pulse from a microcomputer IC11 supplies a large electric current to an electromagnetic coil 3 through ICs 6-8 in an FF circuit and a driver circuit 34. This magnetic flux change quantity is detected by a magnetic flux sensor coil 8, and if the quantity reaches voltage or a magnetic flux change quantity necessary for attracting an armature, a comparator 33, generating an output H exceeding reference voltage V1, cut off an electric current to the electromagnetic coil 3 through the FF circuit. And if the voltage, decreasing flux change quantity necessary for holding the armature to be attracted, the microcomputer, comparing the voltage with reference voltage V2H in a comparator 32, supplies a small electric current to the electromagnetic coil 3 in accordance with on-off operation. In this way, a dynamic range of an injector can be effectively spread.

Title: Ink-jet head
Inventor: FUKUSHIMA TOSHIO
IPC: B41J2/175
Filed: 1983-03-30
Abstract: PURPOSE:To facilitate a multiple-nozzle construction and the like by a method wherein a long rectangular shape electrostriction element is provided to one side of a three-sided three-apex shape ink chamber and a nozzle is provided to the apex which is not adjacent to the side mentioned above and an ink supplying inlet is provided to the bottom end of that side. CONSTITUTION:When a signal voltage is applied to an electrostriction element 18 and the electrostriction element 18 is deformed and vibrates as shown by chain lines, a pressure wave of the vibration is transmitted to the ink in an ink chamber 16 through a plate 17 and transmitted toward the sides (b) and (c). Because the ink chamber 16 has a three-apex shape and the distance between the sides (b) and (c) becomes smaller as those sides come closer to a nozzle 19 provided to the tip from the electrostriction element 18, the pressure wave is amplified as it is transmitted close to the nozzle 19. Therefore, flying energy of the ink becomes very large. The ink chambers 16 have flat shape and can be placed facing each other in parallel with a small distance (t) so that a large number of ink chambers 17 can easily be provided closely.

The agent effectively shields harmful UV-A radiation to protect the skin and is stable to light and heat over a long period. Since the agent is insoluble in water, organic solvents, oily substances, sebum, etc., it is hardly absorbed through the skin. The effect lasts long because of the resistance of the agent to water and sweat. Accordingly, the agent is useful in the fields of cosmetics and pharmaceuticals, especially cosmetic field as an ultraviolet absorber and a cosmetic base.

Then, a gate oxide film 102, a gate electrode 101, diffused layers in source and drain regions and a MOS transistor consisting of an SiO2 film 41 are formed. Moreover, an interlayer insulating film 4 is formed on the film 41 and a film 5, through which an etching can be performed on the material constituting the film 4 in a high selective manner, on which a metal is hardly deposited and which does not contain Si oxide or Si nitride, is deposited on the film 4. Then, connecting holes 6 are formed in the films 4 and 5. Then, a W film 7 is selectively deposited in the holes 6. In this case, W nuclei 8 are recognized on the film 5. However, if this sample is exposed to oxygen plasma, the nuclei 8 are removed along with the film 5. Accordingly, the W film can be buried only in the interiors of the holes 6.
