Abstract:
A hydrogen separator comprising a porous substrate composed mainly of a ceramic having a large number of pores connecting from one surface of the substrate to other surface, and a hydrogen-separating layer made of a hydrogen permselective metal formed on the porous substrate via an intermediate layer made of an electron-conductive ceramic. The hydrogen separator hardly generates defects such as peeling, cracks or the like in the hydrogen-separating layer and is suitable for use even when the hydrogen separator is exposed to a heat cycle, used under high temperature conditions or/and used for long-term.

Abstract:
A hydrogen separator is provided, including a porous substrate having a large number of pores communicating from a first surface to a second surface thereof, and having a hydrogen-separating layer disposed on the first surface so that the hydrogen-separating layer has a penetrated portion extending through the pores from the first surface to a particular depth. An average pore diameter at the first surface of the porous substrate is 0.02 to 0.5 μm, a thickness of the hydrogen-separating layer is 1 to 5 μm, and a penetration depth of the penetrated portion is 0.05 to 1 μm, is at least equal to the average pore diameter at the one surface of the porous substrate, and is not larger than one half of the thickness of the hydrogen-separating layer. The hydrogen separator hardly generates defects such as cracks, peeling and the like in the hydrogen-separating layer, is superior in durability, and provides both good hydrogen-separating ability and good hydrogen permeability.

Abstract:
An object of the present invention is to prevent the fluctuation of output power of converted light oscillated from a wavelength converting device using a non-linear optical crystal. Wavelength conversion devices 1A, 1B converting fundamental wave “A” to light “B” of the different wavelength are provided. The devices 1A or 1B has a wavelength converting layer 2 comprising a plate-shaped body of a non-linear optical crystal and a first main face 2a and a second main face 2b, and a supporting body 3 or 3A joined with the first main face 2a of the wavelength converting layer 2. An additional supporting body 3B may be joined with the second main face 2b of the wavelength converting layer 2.

Abstract:
A method for producing a bonded article composed of a first substrate, a second substrate, and a bonding layer through which the first and second substrates are bonded to one another includes the steps of interposing a water-based bonding agent between the first and second substrates, and forming the bonding layer by heating the water-based bonding agent. The water-based bonding agent contains an alkali metal element, and has a water-soluble compound dissolved therein. The water-soluble compound produces a composite oxide by heating.
Abstract:
A banner page outputting method, at a printer which is connected to a network and is used by plural users in common, in which in case that plural print jobs of a user are outputted in succession and after the plural print jobs a print job of another user is outputted, the banner pages of users are printed out every user, is provided. A printer used this method provides a central processing unit (CPU) for processing print jobs from clients, a user information memorizing means for memorizing user information sending from the CPU via a bus, a user information comparing means for comparing the user information memorized at printing of previous time in the user information memorizing means with user information at printing of this time, a banner page controlling means for outputting a control signal which instructs to print a banner page including a user name, in case that the comparing result of the user information is different at the user information comparing means, and a printer engine which prints the print job including the banner page by an instruction of said CPU. And in case that the comparing result of the user information is the same at the user information comparing means, the banner page is not printed at said printing of this time.
