A solar cell includes a silicon substrate, an aluminum electrode that collects electricity from the rear surface of the silicon substrate, and a silver electrode that extracts output from the aluminum electrode. The aluminum electrode includes an opening formed on the rear surface of the silicon substrate. On a side of the opening is formed a notch that recesses parallel to the direction in which principal stress acts in a plane of the silicon substrate. The silver electrode covers at least the opening and the notch of the aluminum electrode.

A method of repairing a bearing of a wind turbine generator is provided which is able to more permanently repair a gap which occurred between a constituent member of the wind turbine generator and a bearing ring of the bearing. For example, in the case of repairing the gapbetween the main shaft outer cylinderof the wind turbine generatorand the outer ringA of the main bearing, the plateis inserted between the main shaft outer cylinderand the outer ringA, and also the plateis fixed to an inner circumferential surface of the main shaft outer cylinderby the adhesive agent. On the other hand, slip is permitted between the plateand the outer ringA of the main bearing

Cathode ray tube

A light intensity measurement unit can sample the light intensity of scattered light at time intervals of a certain length corresponding to two times the length of each of small equal length sections, into which a measurement area in an optical fiber is divided. A computation unit can then compute the strain and/or temperature of each of the small sections of the measurement area in the optical fiber, based on the light intensity of the scattered light measured by the light intensity measurement unit from the scattering gain coefficient of the scattered light associated with each of the small sections.

A thin flat cathode-ray tube can optimize stress which is generated in each part also when its screen size is increased and maintains high reliability particularly in connection strength in a joint portion between a front glass vessel and a back metal vessel, without deteriorating the joint portion in reliability also in working for mounting electric signal input terminals and an exhaust pipe on the back metal vessel. In the flat cathode-ray tube which is formed by joining side surface portions of the front glass vessel and the back metal vessel with each other, the back metal vessel has the side surface portion of a prescribed width extending along that of the front glass vessel and a bottom surface portion opposed to a fluorescent screen of the front glass vessel, while the bottom surface portion is depressed by a prescribed amount toward the fluorescent portion and a corner portion connecting the side surface portion with the bottom surface portion is at a prescribed radius of curvature.
