Abstract:
A pressure tank includes a liner separated into a cap and a main body. A shell covers the outer surface of the liner. The shell is formed of a fiber reinforced plastic. A heat exchanger is arranged in the liner. A header is connected to the heat exchanger. The heat exchanger is supported on the liner by fastening the header to the cap or the main body.
Abstract:
A hydrogen storage tank includes a tank main body, partition sections, and a hydrogen flow pipe. The hydrogen flow pipe prevents MH powder from passing through and permits hydrogen to pass through. The tank main body includes a hollow body portion having openings on opposite ends. Dome portions are joined to opening ends of the body portion. Partition sections are provided in the body portion so that first retaining chambers, which retain the MH powder, are defined in the body portion. Extended portions, which serve as second partition members, are provided in the dome portions to divide the space in the dome portions into second retaining chambers, which retain the MH powder.
Abstract:
A processing object 2 is sucked and fixed by a sucker 11 and rotated by a rotator 12. In that state, a processing liquid supplied from a processing liquid supply 22 is applied through a processing liquid application tube 21 onto a surface of the processing object 2. Thermal electrons emitted from a thermionic source 33 are accelerated by an acceleration electrode 34 and pass through a Be film 32 to impinge upon the processing liquid on the surface of the processing object 2. When the processing liquid on the surface of the processing object is irradiated with the electron beam, the processing liquid is ionized or radicalized to become active, thereby effectively processing the surface of the processing object 2.

Abstract:
A manufacturing method of a hydrogen storage tank stored with a hydrogen gas by including built-in hydrogen-occlusion alloys, has a stacking step of stacking plate members building up heat transfer fins, an arranging step of disposing the hydrogen-occlusion alloys between the neighboring plate members so as to form an area in which to dispose the hydrogen-occlusion alloys and an area in which to dispose none of the hydrogen-occlusion alloys, and a pressurizing step of forming air spaces sectioned by the plate members building up the heat transfer fins and containing the previously built-in hydrogen-occlusion alloys in a way that gets a part of the plate members deformed by pressurizing the plate members in a stacking direction thereof so as to restrict migrations of the hydrogen-occlusion alloys disposed in the arranging step.
Abstract:
Methods for making hydrogen storage tanks may include disposing a substantially solid block of hydrogen-absorbing alloy within an activation vessel. Hydrogen gas may then be introduced into the activation vessel under conditions that will cause the hydrogen-absorbing alloy to absorb hydrogen and crack or break apart. Preferably, a substantially powdered hydrogen-absorbing alloy is formed thereby. Thereafter, the substantially powdered hydrogen-absorbing alloy can be transferred from the activation vessel to a hydrogen storage tank without substantially exposing the powered hydrogen-absorbing alloy to oxygen. The hydrogen-absorbing alloy is preferably ingot-shaped when introduced into the activation vessel. Further, the substantially powdered hydrogen-absorbing alloy is preferably produced by continuously breaking the ingot-shaped hydrogen-absorbing alloy within the activation vessel due to volume expansion caused by the hydrogen-absorbing alloy having absorbed hydrogen. The hydrogen gas preferably contacts the hydrogen-absorbing alloy under relatively high-pressure and low temperature conditions.
Abstract:
A realtime monitor of an astronomical object such as a double star using speckle interferometry comprises a TV camera for picking up an image of a star which is formed by a telescope, first means for producing an incoherent still picture of the star on the basis of an output from the TV camea, second means for producing a power spectrum of the star by converting the incoherent still picture to a coherent image and then optically Fourier-transforming it, third means for adding the consecutively produced power spectra to obtain an average power spectrum, and fourth means for controlling first, second and third means and calculating a normalized average power spectrum of an object star through dividing the average power spectrum of the object star by that of a reference star.
Abstract:
An MH tank module 2 has a hollow outer shell portion 12 formed of metal. The outer shell portion 12 has a plurality of MH powder retaining chambers 22 defined by a plurality of fins 20. A plurality of MH tank modules 2 are bound together by a first tank holder 10 and a second tank holder 11. The tank holders 10, 11 are each configured by fastening and fixing first, second, third, and fourth holder components 28-31, which are separate from one another. The first to fourth holder components 28-31 each have a heat medium passage 28f-31f. The first to fourth holder components 28-31 each have recessed portions 33 each corresponding to the shape of a side portion of each MH tank module 2. The MH tank modules 2 are held individually by the corresponding recessed portions 33.
