Abstract: In a first step, an input image constituted of a region of interest and a region of non-interest is transformed into plural frequency component images through plural wavelet transforms. In a second step, part of the plural frequency component image is selected as control target images and a region corresponding to the region of interest and a region corresponding to the region of non-interest are set in each of the control target images in a unit of a predetermined coding block. In a third step, among image data of the frequency component images, image data of the region corresponding to the region of non-interest in each control target image is changed to a zero value. In a fourth step, in the unit of the coding block, bit plane coding is applied to the image data changed in the third step without changing a bit plane structure, thereby generating coded data.

Abstract: In order to desirably prevent leakage of a working fluid from the tip clearance to reduce loss of a heat drop of the working fluid, a first corresponding blade of a second stationary blade row, which corresponds to a first reference blade of a first stationary blade row, is disposed in a position distant by 2L from the position of a lower end of a rotor blade in the direction of movement of the rotor blades when the rotor blade makes the closest approach to a lower end of the first reference blade. It should be noted that L is a value obtained by multiplying the average time T required for the high-pressure working fluid to pass through the rotor blade by the traveling speed U of the rotor blade. On the other hand, a second corresponding blade of the second stationary blade row, which corresponds to a second reference blade of the first stationary blade row, is disposed in a position of a lower end of a rotor blade when the rotor blade makes the closest approach to a lower end of the first reference blade.

Abstract: A solenoid-operated cutoff valve for use with fuel cells has a movable member disposed in a guide housing for displacement upon energization of a solenoid. When the movable member is displaced, a pilot valve is unseated from a pilot valve seat. A fluid in a communication chamber flows through a pilot passage into an output port. The communication chamber is divided into a first communication chamber and a second communication chamber by a diaphragm. Under a pressure difference developed between the first communication chamber and the second communication chamber, a main valve of a valve head is unseated from a valve seat of a valve housing, opening the solenoid-operated cutoff valve.

Abstract: A diaphragm is clamped between a solenoid unit disposed in a casing and a second valve body in which hydrogen is introduced. A filter comprising a bottomed cylindrical mesh member is mounted in a first passage defined in the first valve body. A restriction having an orifice for restricting the flow rate of hydrogen supplied to first and second communication chambers is mounted in a first port that is disposed upstream of the filter. The restriction and the filter are disposed coaxially in line with each other.

Abstract: This invention provides a single cascade multistage turbine that has a compact turbine structure having only a single cascade, and enables power to be extracted efficiently in the same way as a multistage turbine having multistage rotor vanes. The working fluid supplied through the supply duct 3 flows on one side of the single cascade of rotor vanes 2 to one part of the circumference direction of the rotor vanes 2, and after passing through the rotor vanes 2 it passes through the circulation ducts 4a and 4b and returns to the former side of the rotor vanes 2. The circulation ducts 4a and 4b consist of exhaust duct members 6a and 6b, return duct members 7a and 7b, and inflow duct members 8a and 8b. Using the circulation ducts 4a and 4b this circulation process is repeated at least once whereby the working fluid is again passed through the rotor vanes 2 at a slightly different position in the circumferential direction of the rotor vanes 2.
