Title: Water injection line
Inventor: HORI MICHIO
IPC: F02C3/30
Filed: 1980-04-18
Abstract: PURPOSE: To increase the output power of a gas turbine and raise its efficiency, by cooling at air the inlet side to a compressor with injecting cool water in a water injection line to a gas turbine combustor.  
     CONSTITUTION: Water stored in a water storage tank 1 passes through a feed water piping 2 and strainer 3 to reach a pump 4, and is increased its pressure to pass through a water control valve 5 and reach an evaporative cooler 6 provided in an inlet housing 7. Here the water performs heat exchanging operation with air sucked from both sides of the inlet housing 7, then the suction air is cooled by the water. The water, which has completed the heat exchanging operation with the air, is collected to a collector in a lower part of the evaporative cooler 6 then boosted to required pressure by a water injection pump 9 to pass through a filter 11 and 14, flowmeter 12, shut-off valve 13, flow control valve 15, feed stop valve 16 and the like, thus reach a nozzle 19 finally injected into a combustor 20.

Title: Device for recording/reproducing optical recording medium
Inventor: TSUJIOKA TSUYOSHI
IPC: G11B7/125
Filed: 1992-03-09
Abstract: PURPOSE:To provide the wavelength recording/reproducing with high density by adjusting the divergent angles of a recording/reproducing beams as to a beam utilized for a focusing servo and providing each beam so as to be converged in the same spot on a medium. CONSTITUTION:When the respective beams with wavelengths lambda1, lambda2, lambda3 of the beam 2 with the same divergent angles are incident onto an objective lens 1 (i.e., correctly collimated), respective beams 6-8 converge on the mutually different spots by means of the objective lens. Since the distance between the objective lens and the position of the laser spot is changed by adjusting the divergent angle of the beam incident on the objective lens, on the course of making the respective beams 6-8 with wavelengths lambda1, lambda2 and lambda3 incident on the objective lens from a light source, the divergent angles are adjusted and the spot 9 is coincident with each other for each wavelength. Consequently, e.g. when the focusing servo is carried out using the beam with the wavelength lambda1, beams with wavelengths lambda2 and lambda3 are correctly focused on the recording film and the reduction of the recording density is prevented.

Filed: 1985-03-16
Abstract: PURPOSE:To enable to provide a desired capacitance ratio even in case of small area and to make the semiconductor device miniature and of high integration, by forming at least one of more than two insulating layers for a gate electrode with material having a dielectric constant different from those of the other insulating layers. CONSTITUTION:On a semiconductor substrate 1, a source region 3, drain region 4 and gate electrode G are formed. The gate electrode G is composed of two conductive layers 6, 7 of gate electrode material and two insulating layers 5, 9, one insulating layer 9 being put between the conductive layers 6, 7. The insulating layer 9 is made of material with a higher dielectric constant than that of the insulating layer 5; for example, the insulating layer 5 is made of SiO2 and the insulating layer 9 is made of Si3N4. Since Si3N4 with a dielectric constant of 8 (about two times SiO2) may be utilized as the insulating layer 9, the capacitance per unit area can be increased and the gate electrode G can be made small so that overlapping between the conductive layer 7 of the gate electrode G and field oxide film 2 can be reduced and thus the memory cell area can be reduced.

Abstract: PURPOSE:To attain efficient motion compensation reduced at its predictive error even when an object having different motion is included in a block by compensating the motion of one block by two motion vectors. CONSTITUTION:Block matching between a current frame 11 and a frame 12 at preceding time is executed to detect a motion vector. Then an outline detecting part 22 judges whether a block in the frame 12 includes an outline or not, and at the time of judging the inclusion of an outline, whether an outline is included or not also in a block of the frame 11 is judged. At the time of judging that both the blocks of the frames 11, 12 include outlines, a motion vector is recalculated based upon the two extracted outlines through a matching error calculating part 30 and a motion vector 43 is outputted. The vector 43 is inputted to a compensating circuit as a motion vector 53 and motion is compensated by using the motion vectors of blocks neighbored each other in a direction divided by the outline.

Abstract: PURPOSE:To prevent an excessive etching of Si3N4 and the short-circuit between a gate electrode and a substrate by forming a thin SiO2 film on an Si3N4 when forming a two-layer gate insulation film of SiO2 and Si3N4. CONSTITUTION:A superthin SiO2 film 14 is formed by laminating an SiO2 12 and an Si3N4 13 to be used for gate on an n-type Si substrate 11, and an Mo 15 is covered on it. A resist mask is provided and CF4 plasma is etched. At this time, the etching speed of the Si3N4 film 14 is reduced by presence of SiO2 14 and does not have a peaked portion. If the SiO2 film 14 is too thick, the Mo film 15 is etched excessively and if it is too thin, it will become of no used and therefore several 10Angstrom  is ideal. Then the etching of SiO2 12 is removed by fluoric acid using the Si3N4 film 13 as a mask, and a p-type source and drain 17 and 18 are provided, excepting the resist 16. With this method, a peaked section is not produced at the gate electrode and also no concentration of electric field is resulted. Accordingly, there happens no short-circuit between the gate electrode and the substrate, and the yield rate and the reliability will be improved.
