Title: Liquids jet type recording head
Inventor: FUNADA RYUICHI
IPC: B41J2/045
Filed: 1986-08-22
Abstract: PURPOSE:To properly perform the transmission of an electric signal and to obtain good printing, by molding a pressure chamber for transmitting high frequency to a liquid to inject said liquid in a finely pulverized state from a single material and forming at least one plane part for bonding an electromechanical tranceducer having a rectangular flat surface to said pressure chamber. CONSTITUTION:An emitting orifice part 1 and a pressure chamber 3 are formed from an inorg. single material or a composite material like ceramic and an electromechanical 5 having a rectangular flat surface is adhered to the plane part 3a of the pressure chamber 3 by an org. or inorg. adhesive and electrically continues to the transducer 5 on the adhesive surface side thereof by an electrode plate 4. When high frequency voltage is applied to the transducer 5, ink is emitted from the emitting orifice 1a of the pressure chamber 3 in a finely pulverized state to perform printing. Since the ink is not directly contacted with the electrode of the transducer 5, there is no restriction due to a liquid kind. Since the thickness of the bonding layer for bonding the transducer 5 and the pressure chamber 3 can be made uniformly thin and the generation of air bubbles in the bonding layer can be suppressed, the transmission of high frequency is properly performed and, even when a plurality of recording heads are provided, the same emitting characteristic can be secured.

Title: Magneto-optical recording medium
Inventor: NAKAMURA HITOSHI
IPC: G11B11/10
Filed: 1989-07-28
Abstract: PURPOSE:To obtain a magneto-optical recording medium suitable for high-speed high- density recording by incorporating a larger amt. of Co into the surface layer of reproducing side of an amorphous magnetic film which consists of rare earth-transition metal alloy containing Co. CONSTITUTION:By irradiating the magneto-optical recording medium such as TbFeCo with laser light, three-dimensionally isotropic temp. distribution is formed, in which the maximum temp. appears at the center of the light spot and temp. is highest on the surface of the magnetic film (reproducing side) and decreases with distance from the surface. Temp. is lowest on the upper protective layer side of the magnetic film, and when magnetization of this part where temp. is lowest is zero, temp. of the surface of the reproducing side must be as high as >=70 deg.C. This phenomenon is the reason why the total sensitivity of the medium can not be degraded even if the Curie temp. Tc of the surface of reproducing side is made higher. By realizing lower Curie temp. as a whole by incorporating a larger amt. of Co only into the surface layer of the reproducing side and reducing the amt. of Co in other parts of the magnetic film, the recording sensitivity can be enhanced as well as the reproducing C/N is increased because of the larger amt. of Co in the surface layer of the reproducing side. Thereby, the obtd. medium is suitable for high-speed, high-density recording.

Filed: 1982-11-08
Abstract: PURPOSE:To achieve an air fuel ratio appropriate to the operating condition of an engine, by connecting a fuel passage through an auxiliary fuel passage to a passage between nozzles coupled in series with each other and by controlling the cross-sectional area of the auxiliary fuel passage depending on the operating condition. CONSTITUTION:When the negative pressure in an intake pipe has become weaker than a prescribed value, a control valve 48 is closed and the flow rate QA of fuel is determined by a first and a second measuring sections 62, 63 made of a first and a second nozzles 36, 38 and a jet needle 61. When the control valve 48 is open, the flow rate QB of fuel is determined only the first measuring section 62 and is about 1.2 time as much as that through only the second measuring section 63. Since a thin air-fuel mixture for stressing the economy is required in the case of the strong negative pressure in the intake pipe and an air fuel ratio for stressing the output is required in the weak negative pressure in the intake pipe, the negative pressure is detected by a negative pressure switch mechanism 52 to turn on or off a solenoid 51 through a switch 59 to open or close the control valve 48.

Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To decide the cell-controlling timing in such a manner as to restrict the change of amount of evaporation to a minimum against the requirement of a large load change in a fluidized-bed boiler in thermal power generation using a split cell method and, moreover, restrict overs and shorts of the amount of evaporation required at the time of change of the load to the minimum and make the deviation of the amount of evaporation small so as to smoothen the change of the amount of evaporation at the time of change of the load. SOLUTION: This boiler accompanies starting and stopping of cells in processes of change of load. In this instance on the basis of a heat input index SV which is an index of change of quantity of heat and which a fluidized-bed boiler should have and on the basis of the quantity of heat H in possession in each of cells the timing for the starting and stopping of cells is so set as to have the deviation A between the change of heat input and heat input index, caused by the increase and decrease of cells in number, smaller. Especially it is desirable to use as a timing for the starting and stopping of a cell the time at which the heat quantity deviation A, when it is about to move or stop, has become about half the heat quantity H in possession of a singular number of or plurality of cells.

IPC: G21D1/00
Filed: 1988-08-09
Abstract: PURPOSE:To effectively inject a corrosion inhibitor by maintaining concentration and holding a hot state stop condition after the pressurizing and pressure reducing operation of water feeding are performed in a condition in which the shell side of a steam generator is filled with water with corrosion inhibitor when a pressurized water reactor is started. CONSTITUTION:The shell side of a steam generator, namely, in a secondary system is filled with boric acid water of 500ppm in a cold state stop condition to start a nuclear reactor. In the halfway, the coolant temperature of a primary system and a secondary system is held approximately 130 deg.C to perform pressurizing and pressure reducing operation of the secondary side of the steam generator. The boric acid water can sufficiently be permeated in a clevis part of the steam generator by the above operation. Thereafter boric acid concentration remains held at 500ppm and the temperature thereof is increased to be in the hot state stop condition. After this condition is maintained for about 10 hours, the boric acid concentration is lowered down to 50ppm to continue the operation. Thereby the temperature and the boric acid concentration for forming a sufficient anticorrosion membrane on a heat exchange surface of the clevis part can be satisfied.
