A hydrogen permeable structure includes a base material (1) including porous ceramic, and a hydrogen permeable film (2) formed on the base material (1), including palladium (Pd) and at least one element other than palladium and having an amount of hydrogen dissolution at a prescribed temperature smaller than that of palladium alone. The hydrogen permeable film (2) is formed on the surface of the porous ceramic base by a physical vapor deposition technique after any pin holes in the surface of the base have been filled with a porous oxide material.

Surfaces of diamond crystals are examined by coating the surfaces with thin metal films, launching laser beams to the diamond surfaces in a slanting angle, detecting defects and particles on the diamond surfaces by the scattering of beams and counting the defects and particles by a laser scanning surface defect detection apparatus. Diamond SAW devices should be made on the diamond films or bulks with the defect density less than 300 particles cm−2. Preferably, the diamond surfaces should have roughness less than Ra20 nm. Diamond SAW filters can be produced by depositing a piezoelectric film and making interdigital transducers on the low-defect density diamond crystals.

There is provided a double walled pipe having an inner pipe and an outer pipe which is movable relative to the inner pipe in a longitudinal direction of the inner pipe. Acting on only the outer pipe with a pipe jacking power makes it possible to bury the double walled pipe, without damaging the rear end of the inner pipe and also generating an internal stress on the inner pipe. Consequently, it is avoided such a situation that even in use pinholes, cracks, etc. occur on the inner pipe, and thus it is possible to expect an execution with higher reliability.

A gear pump rotor is provided including a combination of an inner rotor and an outer rotor whose numbers of teeth are different by one, and the discharge amount of the pump is increased by an increase of the tooth depth. At least one of an addendum curve and a dedendum curve of an inner rotor is formed by a locus of one point on formation circles that satisfy moving conditions that the formation circles move from moving start points to moving end points while changing the distances from an inner rotor center to the centers of the formation circles. The centers of the formation circles move by a distance in the radial direction of a base circle, and the formation circles rotate by an angle at a constant angular velocity in the same directions of the moving directions of the formation circles.

Provided are a Li-ion battery (nonaqueous-electrolyte battery) 100 that includes a positive-electrode active-material layer 12, a negative-electrode active-material layer 22, and a sulfide-solid-electrolyte layer 40 disposed between the active-material layers 12 and 22. The sulfide-solid-electrolyte layer 40 includes a sulfur-added layer 43 in an intermediate portion in the thickness direction of the sulfide-solid-electrolyte layer 40. The sulfur-added layer 43 has a higher content of elemental sulfur than any other portion of the sulfide-solid-electrolyte layer 40. The sulfur-added layer 43 substantially does not have any pin holes. The sulfur-added layer 43 is formed by laminating a positive-electrode body 1 and a negative-electrode body 2 that are individually prepared and subjecting the electrode bodies 1 and 2 to a heat treatment so that a positive-electrode-side sulfur-added layer 14 of the positive-electrode body 1 and a negative-electrode-side sulfur-added layer 24 of the negative-electrode body 2 are softened and integrated.

The solid-electrolyte battery includes a positive-electrode layer, a negative-electrode layer, and a solid-electrolyte layer that conducts lithium ions between the electrode layers, wherein a buffer layer that is a LiNbO3 film is disposed between a positive-electrode active material and a solid electrolyte, and a composition ratio (Li/Nb) of Li to Nb in the LiNbO3 film satisfies 0.93≦Li/Nb≦0.98. The buffer layer may be disposed between the positive-electrode layer and the solid-electrolyte layer or on the surface of a particle of the positive-electrode active material. The buffer layer may have a thickness of 2 nm to 1 μm.

摘要:
In a previous experiment of a deposition work of depositing a film with a uniform thickness on a long strip base material in the longitudinal direction thereof, an elapsed time from the start of the deposition work and an output of a power supply at the elapsed time are measured. The resulting relation between the elapsed time and the output is stored in a storage device. Subsequent deposition on a long strip base material is performed by a method in which first, the output of the power supply is controlled to be stabilized at a desired value using a crystal oscillator thickness gauge in a pre-heating step before the start of the deposition work, and then, a base material transport device is driven to start the deposition work on the long strip base material after a desired deposition rate is obtained. After the start of the deposition work, the output of the power supply is controlled to coincide with the output at the elapsed time stored in the storage device.
