Title: Control method of movable blade propeller water turbine
Inventor: HAYAKAWA KEIZOU
IPC: F03B15/04
Filed: 1983-05-25
Abstract: PURPOSE:To both efficiently discharge air in the periphery of a runner and prevent thrust from its rapid change so as to enable a water turbine to be smoothly operated, by controlling the attitude of a runner blade in consideration of a proper characteristic provided in the turbine when it is switched from condenser operation to generating operation. CONSTITUTION:When a water turbine is switched from condenser operation, in which its runner is rotated in air by depressing a water level 12 below a runner blade 7a by compressed air, to generating operation, first actuating the runner blade 7a to be opened, when its opening of 40% or more is detected by a runner blade attitude detector 9, an air discharge valve 10 is opened by a signal of the detector 9. In this way, the compressed air is discharged, and if the water level 12 rising to a preset level is detected by a water level position detector 11, the air discharge valve 10 is closed while the runner blade 7a also performs its closing action. Then if the runner blade 7a being fully closed is detected by the detector 9, a guide vane is actuated to be opened. And then a load of the water turbine is transferred to a prescribed level by oncome operation, thus performing the generating operation.

Abstract: PURPOSE:To produce an electro-optical element having remarkably improved mechanical strength of a glass substrate and high breakage resistance, by chemically strengthening the surface stress value of a soda-lime glass substrate sandwiching an electro-optical material. CONSTITUTION:An electro-optical material such as liquid crystal is sandwiched and sealed between a pair of substrates at least one of which is composed of a soda-lime glass.

The substrate is immersed in a molten liquid containing an alkali metal ion having larger ionic radius than the alkali metal ion existing in the substrate at 400-500 deg.C, especially 400-450 deg.C for about 1-30min. K<+> can be used as the metal ion in the molten liquid, and any compound meltable at the heating temperature, e.g. KNO3 can be used as the ion source. The surface stress value of the substrate can be increased to 500-1,200kg/cm<2>, especially 700-1,000kg/cm<2> by this chemical strengthening method. The cracking and chipping defects of a soda-lime glass substrate of an electro-optical element can be decreased and the productivity of the element can be improved.

IPC: H04N1/40
Filed: 1993-04-19
Abstract: PURPOSE:To suppress image deterioration at the time of the binarization of an image by compensating miscorrection which is caused at the time of shading correction. CONSTITUTION:A signal in a normal state wherein a sticking matter such as dirt does not stick on a white reference plate is stored in a line memory 3 and a white reference data correction part 13 compares the output of a specific white reference level register 11 for the specific position of white reference data 9 just before a document image is read out with the output signal level of a white reference level register 12 for the same address position in the line memory to finely adjust a reference signal, document by document, by arithmetic. Then the white reference signal is prevented from being misdetected owing to the dirt or stain on the white reference plate during document conveyance and variation in the read level of the white reference due to temperature variation of a light source is corrected. Consequently, the miscorrection due to the shading correction is compensated to obtain gradation reproducibility of binarization without deterioration in picture quality.

Abstract: PURPOSE:To ensure automatically sealed condition by operating and controlling an air-feeding device in such a way that the presence in a closed crosssectional face is higher than the pressure in a sterilizer main body, pressing a seal member to the sterilizer main body side through a door lid plate and ensure a hermetic property of the sterilizer main body. CONSTITUTION:To improve sealed condition between a door lid plate 2B and a sterilizer main body 1, the door lid plate 2B is pressed on the sterilizer main body 1 at a pressure W0 which is a pressure W1 in the sterilizer main body 1 or larger and a relation of W1+H<W0 as the pressure condition in this case holds wherein H is a mechanically-clamping pressure of a packing etc. When a door is closed and the difference in pressure between the inside of the sterilizer main body and the inside of the closed crosssectional face of the door side is detected by means of a pressure difference detecting device 18, if the pressure in the closed crosssectional face of the door side does not satisfy the relation of the said equation, a signal for feeding air is output to an air-feeding device 19. Air is fed in the closed crosssectional face of the door side and the pressure in the closed crosssectional face is elevated. A door lid plate 10B1 forming one side of the wall faces of the closed crosssectional face is displaced to the side of the sterilizer main body 11 and a packing 16 is hermetically adhered on a flange 11A to suppress the leakage of a pressure medium from the side of the sterilizer main body 11 and to prevent the pressure from decreasing.

Filed: 1990-04-06
Abstract: PURPOSE:To provide the optical fiber amplifier having an excellent amplification characteristic by doping an active element near the boundary between the core and clad of an optical fiber and stretching the optical fiber in a prescribed part, thereby reducing the diameter thereof. CONSTITUTION:An optical multiplexer 2 and an optical demultiplexer 3 are provided on both sides of the optical fiber 1 and the stretched part tapered in the central part of the optical fiber 1 is formed by heating and stretching this part. The diameters of both the core and clad of the optical fiber 1 are thereby reduced. The active element ions are mainly doped near the boundary (hatching in Fig.) of the core and the clad. The greater part of exciting light and signal light propagates in the part (non-stretched part) where the diameter of the optical fiber 1 is not reduced and, therefore, the absorption by the active element ions is not a problem but a part of the exciting light and the signal light bleeds out to the clad in the part (stretched part) where the diameter is reduced. The optical amplification by the active element ions is thus executed. The amplification characteristic is improved in this way.
