Abstract: Electrons are copiously emitted by a device comprising a loop-shaped filament made of lanthanum hexaboride. The filament is directly heated by an electrical current produced along the filament by a power supply connected to the terminal legs of the filament. To produce a filament, a diamond saw or the like is used to cut a slice from a bar made of lanthanum hexaboride. The diamond saw is then used to cut the slice into the shape of a loop which may be generally rectangular, U-shaped, hairpin-shaped, zigzag-shaped, or generally circular. The filaments provide high electron emission at a relatively low operating temperature, such as 1600.degree. C. To achieve uniform heating, the filament is formed with a cross section which is tapered between the opposite ends of the filament to compensate for non-uniform current distribution along the filament due to the emission of electrons from the filament.

Abstract: Disclosed is a tape cassette having a front cover urged in the direction for covering, by pivoting, a tape stretched along the front surface of a cassette case, and a cover-locking piece adapted to pivot within a plane thicknesswise of the tape cassette while being urged in the direction for holding the pivoting of the front cover when it is not in use. The tape cassette is further provided with an optical path aperture formed in a side surface portion thereof in order to form an optical path through the tape stretched inside the tape cassette when it is in use. The tape cassette is improved in its assembling efficiency while preventing disengagement of urging springs thereof in assembly. Moreover, it is possible to obtain satisfactory functions of the front cover and the cover-locking piece while preventing foreign matter such as dust from entering the inside of the tape cassette by covering the optical path aperture when the tape cassette is not in use. Furthermore, the tape cassette can be made microminiature by permitting the required widthwise dimension thereof to be extremely small.

Abstract: A one-piece, directly heated cathode is disclosed for use in a cathode ray tube electron gun. The cathode according to the invention has the configuration of a hollow cylinder with one closed end for receiving a thermionic electron-emissive coating. A pair of body portions extending axially in the same direction from diametrically opposed sides of the closed end define two legs which act as serial electrical conductors having inherent resistance for use in resistively heating the electron-emissive coating. The legs have an arcuate cross-section effective to structurally stabilize the cathode and suppress temperature-induced lateral displacement of the cathode which would otherwise degrade the performance of the electron gun.
