A mesh sheet of the present invention is a mesh sheet in which a metal mesh comprising fine bands is laminated on a surface of a base substrate, the mesh sheet being used and adhered along a surface of an arbitrary member having a curved surface portion. The metal mesh has a part in which the fine band positioned between connection points of the fine bands which are adjacent to each other is a curved line so as to absorb stress relative to deformation to be placed along the curved surface portion with a large curvature without destructing the metal mesh.

An apparatus for measuring angular velocity is provided with a microwave oscillator, closed-loop waveguide and a microwave-detector. The microwave oscillator generates microwaves and the waveguide which may employ a magic tee as a part thereof separates the microwaves to propagate one and the other of separated microwaves clockwise and counterclockwise therethrough, respectively. The microwave detector mixes and microwave-detects one and the other of the separated microwaves propagated through said waveguide. When the waveguide is in rotary motion, frequencies or phases between the separated microwaves differ from each other in dependence upon the angular velocity and the microwave detector produces an output signal corresponding to the difference in frequencies or in phases between the separated microwaves. The angular velocity of the waveguide is measured by the use of output alternating signal component corresponding to the frequency difference between the separated microwaves or by the use of output direct current signal component corresponding to the phase difference between the separated microwaves.

A radiation-hardened semiconductor device including a bipolar transistor is disclosed in which a highly-doped layer equal in conductivity type to and larger in impurity concentration than the base region of the transistor is formed in that portion of the surface of the base region which exists beneath an insulating film, to prevent minority carriers injected into the base region, from reaching the above-mentioned surface portion. Thus, the injected minority carriers can reach a collector region without being extinguished by the recombination at the surface of the base region.
