The present invention relates to a fuel cell structure incorporated in a fuel cell device and a fuel cell device including such a fuel cell structure. The fuel cell structure (4) according to the present invention incorporated in a fuel cell device comprises a tubular fuel cell (6) and a support plate (12) through which an end (6a) of the fuel cell extends and to which it is fixed. The fuel cell (6) has an inner electrode layer (16), an outer electrode layer (20), and an electrolyte layer (18) disposed therebetween. The fuel cell (6) also has, on an outer peripheral surface at the one end (6a) thereof, an inner electrode exposed periphery (16a) where the inner electrode layer (16) is exposed. The one end (61) of the fuel cell (6) and the support plate (12) are sealingly fixed to each other with a conductive sealer (32). The sealer (32) extends onto the inner electrode exposed periphery (16a) and is spaced from the outer electrode layer (20).

A method for producing a thin layer device such as a superconductive device excellent in mechanical strength and useful as a submillimeter band receiver is provided. The thin layer device is produced by forming a multilayer structure substance comprising an NbN/MgO/NbN-SIS junction on an MgO temporary substrate, then forming SiO2, as a substrate, on said multilayer structure substance, and subsequently removing the MgO temporary substrate by etching. A superconductive device (a thin layer device) produced by a method of the present invention has excellent performance and high mechanical strength, and therefore introduction to a waveguide for a submillimeter band is also easy.

摘要:
A laser beam is focused at positions on an optical axis of the optical pickup by a focusing device, corresponding to kinds of the discs which are different in thickness. The focusing device is moved along the optical axis. A photodetector is provided for receiving a laser beam reflected from the disc and for producing a focus error signal. A detector is provided for detecting the difference between the focus error signals, caused by the difference in thickness of the discs and the difference in focal point of the laser beam, thereby discriminating the kind of the disc.

A bias material for magnetic markers is produced by plastic working to provide a strip form, which has a metal structure consisting of the iron-base matrix and a non-magnetic copper group metal phase in an amount of not less than a solubility limit thereof in an equilibrium state at a room temperature. The non-magnetic copper group metal phase is dispersed in the matrix so as to form a microstructural rod pattern. The bias material comprises preferably 3 to 35% wt % of a copper group metal. The magnetic marker is produced by combining the bias material and a magnetostriction element.

摘要:
After a principal current through an SCR has been decreased to zero by inverting the polarity of the voltage between the main terminals of the SCR(anode voltage,) its gate is reversely biased with a gate bias pulse including a time point where the anode voltage passes through a zero point toward the positive direction. Also, the gate is reversely biased with a gate bias signal in the form of a direct current less in amplitude than the bias pulse. The bias signal may be in the form of a pulse consecutive to the bias pulse and terminating not earlier than the termination of the OFF-state voltage.
